2009 Audi A4 Press Release Bookmark


Audi announces 2009 MY pricing for the all-new A4 sedan and Avant models

HERNDON, Va. – Audi of America today released pricing for two of its newest entries, the 2009 model year Audi A4 sedan and A4 Avant.  Manufacturer’s Suggested Retail Price for the A4 sedan will start at $32,700, while MSRP for the A4 Avant will start at $34,500.

“The combination of efficiency, power, performance and design make the A4 the new segment standard,” said Johan de Nysschen, executive vice president, Audi of America.  “These are all-new models with added standard features versus the previous generation.  And the A4, when equipped with the all-new 2.0TFSI engine and quattro all-wheel-drive system, delivers better fuel economy and acceleration than the key competitors in this segment.”

Audi will begin delivery of customer orders in September 2008, but de Nysschen said that some dealers will have vehicles available for consumer test drives as early as the week of August 10th.

Blake Strong, dealer principal of Strong Audi in Salt Lake City and Audi dealer council chairman, noted that dealers have seen considerable interest in the coming A4 launch.

“I started getting calls early this year,” said Strong, “especially after the A4 hit the auto show circuit and photos started to appear.  Consumer interest increased as fuel prices rose.  The new 2.0 TFSI is a great engine.  Add the new engine to the beautiful design and incredible vehicle technology and I feel that this is the perfect car for the time.”


The Audi A4 sedan can be equipped with either the all-new 2.0 TFSI 4-cylinder engine or the 3.2 FSI V6 engine.  The 2.0 TFSI engine can be configured for front-wheel drive or with Audi’s quattro all-wheel-drive system.  The 3.2 FSI is offered exclusively in the sedan and with the quattro all-wheel-drive system and a 6-speed Tiptronic transmission.  The A4 Avant will be equipped with the 2.0 TFSI engine and the quattro all-wheel-drive system.


New for 2009, the 2.0 TFSI engine features more horsepower (211 hp) and significantly more torque (258 lb.-ft.) than the engine it replaces.  Rated at 21 miles per gallon city and 27 mpg highway, the 2.0 TFSI engine delivers better fuel economy, and when compared to the all-wheel-drive versions, better 0-to-60 miles per hour acceleration than the key German and Asian competitors in the segment.


Audi of America offers a full line of German-engineered luxury vehicles, including the Audi A4. This eighth-generation A4 made its global debut at the Frankfurt Motor Show in September 2007 and its North American debut at the North American International Auto Show (Detroit) in January 2008.  During 2007, Audi sold 322,517 A4 models globally, and 45,411 in the United States (nearly 50 percent of all Audi vehicles sold in the U.S.).

THE NEW AUDI A4
 
 
Sporty and superlative, progressive and emotive – the A4 takes Audi into a new
dimension in the midsize car segment.  The two FSI direct injection gasoline
engines provide supreme performance with fuel consumption that is more than 10
percent lower than the previous model.  The highly efficient engines are clear
evidence of Audi’s outstanding technical expertise. The dynamic suspension and
many other technologies have been adopted directly from the large luxury class. 
The Audi A4 reaches the U.S. market in Fall 2008.
 
A new language: The design 
 
Compared to its predecessor, the designers tweaked the proportions into a new
sporty ratio. The front overhang was shortened, and the hood and the wheelbase
were extended visibly. The new A4 measures 4.70 meters (15.42 feet), nearly 12
centimeters (4.6 inches) more than its predecessor. The body also documents the
advances: It is significantly stiffer and safer than its predecessor, while, at the
same time, dropping about 10 percent of its weight thanks to intelligent light-
weight steel construction. 
 
With a base size of 480 liters (16.95 cubic feet), and in the sedan 490 liters (17.30
cubic feet), the new Audi A4 has a larger trunk than any of its immediate
competitors. With the Avant, when the rear seat backs are folded down, the cargo

space reaches up to 1,430 liters (50.50 cubic feet). The rear backrest is split at a
ratio of 40:60, with an optional separate ski and snowboard bag. The A4 rolls off
the line with sophisticated solutions such as a reversible cargo floor and a
convenient cargo cover. Audi provides a number of optional luxury features, like
an electro-mechanical tailgate drive and a luggage retainer set. 
 
Light and spacious: The interior
 
The ambience inside the new A4 is light and spacious. Compared with its
predecessor, knee room has been increased by 36 mm. The same goes for the
headroom of up to 971 millimeters (38.23 inches) in the Avant. The interior
reflects Audi’s traditional strengths – a noble impression, uncompromising quality
of workmanship with attention to every detail, and logical, intuitive operation. 
 
The cockpit is driver-oriented, with the center console tilted by eight degrees to
the left. In the design of a great many details, the A4 has taken cues from the
larger A8. The instruments bear the classic Audi look, but with further
developments.
 
Thanks to the new electro-mechanical parking brake, the manual parking brake
lever is no longer necessary. Even the standard climate control system is a
completely redesigned component. It supplies 10 percent more cooling capacity,
yet operates 20 percent more efficiently than the previous system.
 
Slipping into the ergonomic perfection of the seats of the new A4 provides yet
another typical Audi effect – you feel at home from the first moment on. Also,
when it comes to safety, Audi has raised the bar: The adaptive airbags and two-
stage belt force limiters have been even more finely tuned, providing better
protection for passengers. The backs of the front seats and the head restraints
support the upper body in case of a rear impact. This integral headrest system has
received high praise in independent tests.
 
The engines: More performance, greater fuel efficiency
 
The new Audi A4 will be launched with two powerful and smooth-running
gasoline engines, which cover a range of 211 hp to 265 hp. All the powerplants
have direct fuel injection, and the four-cylinder gasoline engine utilizes
turbocharger technology which provides high torque.
3/34
The 2.0 TFSI is a new development, operating with the innovative Audi valvelift
system (AVS), which varies the lift of the exhaust valves. In a slightly different
form, this technology also benefits the 3.2 FSI by providing a further performance
increase combined with greater fuel efficiency. All in all, fuel consumption by the
gasoline engines has dropped by more than 10 percent, a convincing testimony for
Audi’s efficiency strategy.
 
Both gasoline FSI engines are available with the quattro permanent all-wheel
drive, which is optional on 2.0 TFSI or standard on 3.2 FSI.  Under normal
driving conditions, this distributes the forces at a ratio of 40:60 between the front
and rear axle. This emphasis on the rear end perfectly harmonizes with the overall
dynamic character of the new A4.  If needed, the self-locking center differential
transfers the majority of the torque to the axle with the better traction.  As in the
past with all North American models, all A4 Avant models always have quattro as
standard equipment.  
 
In the driveline of the new A4, the differential has moved directly behind the
engine. It has switched places with the clutch or the torque converter, making it
possible to move the front axle 154 millimeters (6.06 inches) forward. This
solution provides for a longer wheelbase, a shorter front overhang and a balanced
distribution of the axle loads, thus improving handling in particular.
 
Completely new: The dynamic suspension 
 
The dynamic suspension of the new Audi A4 was redesigned from top to bottom. 
The pivot bearings and the five links per wheel that make up the front axle are
made of aluminum, just like the front cross member, which gives the front end of
the body more rigidity. The steering box is located far to the front and deep down
so that the steering impulse can be led directly to the wheels via the tie-rods. The
rack-and-pinion steering provides an immediate feel for the road, and its highly
efficient servo pump improves fuel consumption.
 
For the rear axle, Audi applied the track-controlled trapezoidal link principle of
the larger A6 and A8 series. For the most part, the suspension is made of
aluminum; the separate layout of the springs and shock absorbers produces subtle
responsiveness. Starting with the 211 hp engine, the new A4 will roll off the 
4/34
production line on 17-inch alloy wheels. Behind these wheels are powerful
brakes; the front disks are ventilated. The electronic stabilization program (ESP)
can be partially disabled when driving below 100 km/h (62.14 mph).
 
In connection with Audi drive select, there are two additional modular
components. One of them is an adaptive controller for the shock absorbers that is
linked to a sports suspension which lowers the body by about 20 millimeters (0.79
inches). The second component is Audi dynamic steering, which operates using a
superposition gear. Depending on the driving speed, it varies the steering ratio
continuously. In the limit range, it works with ESP to stabilize the new A4 Avant
with small lightning-quick steering interventions. The system is also extremely
useful when understeer occurs and when braking if traction is only available on
one side. The leading-edge Audi dynamic steering system far surpasses solutions
offered by the competition. 
 
Even greater supremacy: The assistance systems 
 
Upon request, Audi equips the new A4 with a wide range of high-tech systems
that are derived from the luxury class and make driving an even more supreme
and relaxed experience. These include the Audi parking system and available rear-
view camera and the lane change assist system Audi side assist, which warns of
hazardous lane changes. By way of automatic acceleration and deceleration,
adaptive cruise control maintains the pre-selected speed, taking the distance to the
vehicle in front into account. 
 
The Audi A4 also sets new standards in one of the most fascinating technical
fields of the future – multimedia. The Audi Music Interface (AMI) is available for
the audio systems concert and symphony and fully integrates an iPod with all its
functions. 
 
As additional upgrades, customers can order the navigation system with DVD and
MMI. These allow the integration of a cell phone in the form of a Bluetooth car
phone, and they are combined with the market-leading MMI operating system.
The epitome of hi-fi enjoyment is the sound system by the luxury Danish brand
Bang & Olufsen: 505 watts of sound power, controlled through 10 active channels,
supplying 14 speakers.

The exterior design
 
The new Audi A4 exudes dynamism and athleticism. Its architecture of new
proportions is charged with strength and emotion and underlines the leading
position Audi occupies in the area of automotive design. 
 
With its length of 4,703 millimeters (185.16 inches), and a width of 1,826 mm
(71.89 inches), the new Audi A4 clearly surpasses its most important competitors,
while it stays below them in height (only 1,436 mm (56.53 inches)). These sporty
proportions follow the premise of elevated dynamics. Compared to the
predecessor, the new A4 has been extended nearly 12 cm (4.6 inches) in length
and 6 cm (2.36 inches) in width, while, at the same time, the front overhang was
shortened and the hood and wheelbase were extended. The new A4 not only
provides a higher degree of stature but also more power than its predecessor.
 
The body: Sculpted in one piece
 
In the new A4, the Audi designers have reinterpreted classic themes from the
range of shapes used by Audi. The result is a focused, taut design – a personality
with self-assured carriage. The coupe-like, early sloping roof line turns the entire
silhouette into a flow of elegance, while dynamic lines frame and emphasize
curved sculpted surfaces. In its precision, the design conveys the objective of
uncompromising quality to which Audi is committed. 
 
The front end of the new Audi A4 underscores the image of self-confidence.
Compared to its predecessor, the single frame is wider and lower. The grille is
finished in stone gray; on the most powerful engine model – the 3.2 FSI – it
comes in high gloss black. 
 
Depending on the version, headlights differ by a few details. Especially eye-
catching are the chrome finished “wings,” which differ between the halogen and
the xenon plus headlights. On the halogen lights, the wing shapes a second, short
wing, while the xenon plus units are embedded in a single curved wing. 
 
7/34
Both versions feature the daytime running lights. With the halogen lights, it is
generated by incandescent bulbs, while the xenon plus headlights each have 14
integrated white LEDs, with a total power consumption of only nine watts. The
daytime running lights, which were pioneered by Audi, not only represent a
significant safety technology, but a consistent styling characteristic; they give the
face of the new Audi A4 its unmistakable expression. All engine versions share
halogen fog lights integrated into the air intakes in the lower front end.
 
Poised power: The side profile 
 
The profile of the new Audi A4 also conveys the impression of forward-urging
power. The long, powerful hood and the correspondingly set-back passenger cell
paint the picture of dynamic energy. 
 
In the side view, a sophisticated interplay of ascending and descending lines
produces a dynamic feel without interfering with the overall balance. The sill area
is the foundation, with the dynamic line above it extending all the way to the rear
of the car. It rises toward the rear in a sweeping curve, thus shifting the visual
center of gravity to the middle of the new Audi A4. 
 
The tornado line, on the other hand, located just below the windows, descends
toward the back. Accented by a distinct seam, it projects beyond the front and the
rear wheel wells like a line drawn by a steady hand. The “feature line,” a slightly
slanted edge of the roof contour, gives the window area a flat and elongated
impression. 
 
The body 
 
The body of the new Audi A4 employs new high-tech materials and processes,
and it is stiffer and safer than its predecessor, while its weight has been reduced
considerably even though it is longer and wider. With a drag coefficient of 0.27
for the sedan and 0.31 for the Avant, it glides lightly through the wind. 
 
The new Audi A4 is unusually sizeable and spacious. With it long wheelbase of
2,808 mm (110.55 inches) it clearly beats the competition. The generous interior
space, the high degree of stability, and the supreme straight-line stability all
benefit from this long wheelbase.
 
8/34
Moving the front axle forward was what made this long wheelbase possible. This
was facilitated by moving the differential 154 millimeters (6.06 inches) forward
directly behind the engine – in fact, it switched places with the clutch (or the
torque converter). This solution also allowed for the subtly balanced distribution
of the axle loads – thus providing for the driving excellence that captivates in the
new Audi A4. For the same reason, the battery was moved into the cargo area.
 
Lightweight steel construction
 
One of the great strengths of the new A4 is its low weight – benefiting both sporty
driving qualities as well as low fuel consumption. The sedan and Avant are both
extremely lightweight, although much larger than their predecessor.  The sedan is
10 percent lighter, while the Avant is nine percent lighter. 
 
A prime example of the new technologies applied by Audi to the A4 are found in
the body structure, where hot-formed ultra-high-strength steel materials are
utilized. On the new A4, they are utilized principally in those areas where only
minor deformation is permitted – for example reinforcement of the center tunnel,
the inner sills, the B posts and the firewall transverse beams in the engine
compartment. In hot forming, boron alloyed steel plate blanks are heated in an
oven to about 950 °C (1,742 °F) and then formed in cooled presses while being
quenched. The molecular structure created in this way features a tensile strength
of up to 1,600 Megapascal.
 
As well as conventional resistance spot welding, Audi relies on a sophisticated
structural bonding agent in many areas. This bonding agent increases the stability
of the connection and thus improves the rigidity and crash characteristics of the
body structure. 
 
In addition, Audi employs two further sophisticated joining technologies. Laser-
beam welding is used for the sill area and the doors. In the visible area of the
tailgate rain duct, as well as the zero-gap joint between side element and roof, the
relevant components are joined by plasmatron brazing. Here, Audi’s high-tech
character and quality approach are evident, complemented by close joins
throughout the body.   Further proof of this high standard has been provided for
many years by the fully galvanized bodyshell, which enables a 12-year warranty
against body penetration by rust to be offered.
 
9/34
The highest standard possible: Occupant protection 
 
Occupant protection also reaches the highest possible standard in the new Audi
A4. For this development, the brand makes use of the broad knowledge base
acquired from its own research: All over the world, the AARU (Audi Accident
Research Unit) looks into actual accident situations and evaluates relevant data. 
In the United States, this research has paid off, as the last generation A4 achieved
IIHS (Insurance Institute for Highway Safety) “top safety pick” results, earning
top frontal, side, and rear crash safety scores for the past few years.
 
In a frontal collision, the new A4 protects its occupants with an exactly planned
sequence of measures. At the onset of the crash, two acceleration sensors located
below the headlights are activated. The front cross-member distributes the forces
to the side members, which, thanks to their carefully designed deformation,
absorb this energy. The aluminum subframe diverts the forces and momentum in a
controlled manner into the floor and tunnel structure of the occupant cell. The
steering column can be deformed backwards by up to eight centimeters (3.15
inches), while the main elements of the pedal assembly can be released from their
mountings. 
 
In a head-on crash, small people are still at considerably greater risk than tall
occupants. Audi therefore has networked the occupant restraint systems more
closely together than on any midsize car produced so far.
 
Sensors on the seat rails check the front seat position; this way, the computer can
calculate how far the seat occupant is from the airbag and can ensure that the
amount of forward movement – during which the seat belt and airbag can restrain
the body – is optimally utilized. 
 
The airbags in the new Audi A4 are adaptive and operate based on a new strategy:
they always inflate fully. If the control unit assesses the situation as relatively
harmless – that is if the impact is not too violent and the seat occupant is sitting
close to the cockpit – part of the gas from the airbag is discharged again through
valves, so that the head and chest of the occupant are restrained relatively gently.
If the crash is severe, the airbags remain fully inflated for longer. The same
procedure occurs if the impact is not very strong, but if the passenger is sitting so
far back that her or his torso would whip forward with great force. 
 
10/34
Even more safety: Adaptive belt force limiters 
 
The seat-belt force limiters also use an adaptive operating principle, with two
integral torsion bars linked by gear wheels. In a less critical situation, the torsion
bars are separated at an early stage in the accident. This gives the belt a greater
range of movement – the torso plunges relatively deeply into the airbag and the
load on the chest is reduced. In a more severe crash situation, however, the torsion
bars are either disconnected later or not at all – the seat belt restrains the passenger
more firmly. 
 
Inside the car, occupants are protected by seat-integrated sidebags with a volume
of 13 liters (793.31 cubic inches) for the front seats (sidebags with a volume of 12
liters (732.28 cubic inches) are an option for the rear seats) and large side curtain
airbags (25.5 liters – or 1,556.10 cubic inches). 
 
Furthermore, driver and front passenger in the new Audi A4 are effectively
protected by variable-height seat belts, not available among some of its
competitors, head restraints with a generous amount of vertical adjustment, and
anti-submarining ramps in the seats. A sensor recognizes if the passenger seat is
occupied. 
 
Rear-end collisions also lose much of their injury potential in the new A4. The
side members and the rear subframe absorb the kinetic energy by deforming,
while the rear wheels make contact with the body sills if necessary. The seats and
head restraints are designed to protect the upper body of front seat occupants
against a whiplash impact from the rear. This integral head restraint system
already has been highly praised in independent tests. In case of severe rear-end
collision, the seat-belt tensioners are triggered to firmly hold the occupants in the
best position in their seats. 
 
Rigidity: Basis for comfort and dynamic handling
 
The rigidity of the new Audi A4’s body is the basis for the peaceful ride, with
virtually no unpleasant noise or vibration. At the same time, the rigid body shell is
the key to the car’s outstanding road behavior – ensuring smooth running and
sporty precision in its handling.
 
11/34
One challenge for the development engineers was to offer the customer the same
high levels of vibrational and noise insulation and comfort if a panoramic sunroof
is selected in the A4 Avant. In its basic version, the panoramic roof would lead to
reduction of body rigidity and a deterioration in the qualities named above. In the
A4 Avant, for example, the panoramic sunroof is fixed rigidly to the body by
means of a reinforcing frame. This not only secures the roof module compactly, it
also considerably improves acoustic comfort.
A great degree of focus was placed by the engineers on local rigidity as well. All
locations where driving operations produce interference and vibrations have been
targeted for reinforcement, such as the connection of the front suspension
crossmember to the wheel suspension and the body. The front crossmember, for
example, distributes the frequency impulses from the wheels into a multi-element
structure consisting of the side members and tunnel elements – thus greatly
reducing the tire roll noises in significant body areas.
 
Perfect peace: The aeroacoustics
 
The new Audi A4 is a very quiet car. With intensive detail work, wind roar – the
biggest source of noise above 120 km/h (74.56 mph) – was significantly reduced
below the level on the previous model. An important development tool in this
work was Audi’s extremely quiet aero-acoustic wind tunnel. 
 
In the basic version, the new Audi A4 achieves an exemplary drag coefficient of
0.27 for the sedan and 0.31 for the Avant.  This is significantly less than the
previous model (sedan 0.31 and 0.33 for previous Avant). Even though the wider
body increases the frontal area from 2.14 m2 (23.03 square feet) to 2.20 m2, (23.68
square feet), overall drag has been reduced by more than three percent on the
sedan. 
 
The cargo area (Avant)
 
Beautiful wagons are called Avant – intelligent and practical wagons as well. The
new Audi A4 Avant once more offers a meticulously thought-out cargo area
concept. The basic measurements alone impress with their generosity. The length
of the loading space is 1.03 meters (40.55 inches), and the load-through width is
exactly one meter (39.37 inches). Two golf bags can be stored across. The volume
is 490 liters (17.30 cubic feet) – unmatched in its field of direct competitors.
 
12/34
A characteristic Audi feature is the elaborate design of the cargo area. It is lined in
its entirety with high-quality velour carpeting. Four strong lashing eyes in the
floor are standard. The two hooks in the upper sides are made of chrome-plated
metal. The precision with which they can be adjusted exemplifies the
uncompromising quality standard of the brand with the four rings, which extends
to even the smallest of details. 
 
Luxury special: Electromechanically operated tailgate (Avant)
 
Life with the new A4 Avant is made even more comfortable by new luxury
technologies available upon request. Opening and closing of the
electromechanically operated tailgate is performed by electric motors in the
hinges; they are controlled by the remote control car key, the electric handle in the
tailgate itself, or by a button in the driver’s door. To close it, a switch on the
tailgate underside is activated. 
 
The required opening angle is infinitely programmable, which avoids collision
with low garage ceilings and accommodates smaller persons as well. 
 
The interior
 
More space, comfort and sporty elegance – the ambience on board the new 
A4 is bright and spacious. It meets you with distinguished visual details; as usual
in an Audi, no compromises are made in the quality of workmanship, and the
controls can be understood and operated intuitively. Once you take a seat inside
the new A4, you experience a typical Audi effect – a feeling of being absolutely at
home from the very first moment.
 
The front seats also are equipped with many pleasant features. In addition to the
bottle holders in the large door pockets, there are two more cup holders on the
center tunnel, a holder for sunglasses, a parking claim ticket clip and a large glove
box. 
 
For the front seats there is a center armrest that can be moved forward and back
and varied in height, and it includes a storage compartment and two 12V power
sockets. The thickly padded armrest element is of particularly generous
dimensions because the new electromechanical parking brake eliminates the need
for the conventional handbrake lever. 
13/34
Perfect integration: The front seats
 
Audi offers standard electrically operated front seats, including adjustment for
seat height, forward/back movement, and seat-back angle. The four-way driver
lumbar support is operated electrically as well. There is also a memory function
available, along with seat heating that can be controlled in six stages – a typical
Audi feature. The sports seats have boldly contoured side sections for firm
support. The angle of the seat cushions can be adjusted and extended forward. 
 
Driver orientation: Centered around the person at the wheel
 
The cockpit has a definite bias toward the driver, so that all functions are turned
toward the person behind the wheel. The center console is inclined by eight
degrees toward the driver. Complex graphics and the clear layout of the various
zones communicate the athletic power and lightness that can be felt in every
aspect of the new A4’s character.
 
In many details, the new A4 has the sophistication of the A8 luxury sedan. All
switches, for example, have short travel and lock into place when a defined
amount of force is applied to them. The rotary knobs move as smoothly and
precisely as the mechanism of a fine watch, and their ‘click’ is the sound of pure
technical perfection. The instrument cluster, although it is a completely new
development, presents the classic Audi design elements. 
 
In every Audi A4, a 6.5-inch color monitor is standard; it is located in the upper
part of the center console and is therefore extremely easy to see. This large
display screen displays information from the audio and air conditioning systems
as well as from the CAR menu, where the customer can configure many functions
of the new A4. The large switches and pushbuttons of the standard audio system
“chorus” with CD drive and MMI operating logic are ideally accessible just above
the automatic climate control system – also standard – in the center console. 
 
With the optional DVD navigation system, a seven-inch color screen is provided,
and MMI controls are behind the shift knob.
 
14/34
Advanced comfort: The electromechanical parking brake
 
Close to the MMI buttons, there is another large switch that controls the new
electromechanical parking brake, which is another luxury-class solution that
simplifies the center console. Like the conventional handbrake, the parking
brake’s function is to prevent the car from rolling away. If the conventional brake
system should fail, there is also an emergency brake function integrated into the
electromechanical parking brake with a retardation rate of eight m/s2, scarcely less
than a full brake application. In addition, the integrated drive-off assistant
supports the driver when the car is set in motion.
 
The standard climate control system in the A4 is an entirely new development.
Compared to the previous version, it provides 10 percent more cooling power and
still yields 20 percent higher operating efficiency. As an option, a luxury version
is available, where the comfort climate control regulates the air temperature,
airflow volume and air distribution in three separate zones. 
 
The new remote entry key for the A4 has no projecting teeth. To start the engine,
it is pressed into the ignition lock. It stores service information and warning
messages that simplify and speed up the reception procedure when the A4 is
brought in for service. There is also the luxury option of the advanced key. This
key stays in the driver’s pocket, and the engine is started and stopped using a
start/stop knob on the center tunnel. The lock system releases the locks by a
sensor as soon as the driver touches a door handle, or the tailgate release button
locks again if the sensor in one of the four door handles is pressed. 
 
In the headlights as well, Audi offers various upgrades. The xenon plus headlights
are the high-tech solution, which includes dynamic range adjustment, raising the
beam at speeds above 120 km/h (74.56 mph) for highway driving. 
 
The engines
 
More power, lower fuel consumption – the new Audi A4 is being launched in
North America with a choice of two powerful yet refined engines. All
powerplants have direct fuel injection – the engines use FSI technology while the
four-cylinder gasoline engines are turbocharged – with a correspondingly
impressive torque. 
 
15/34
With their splendid flow of power, the powerplants in the new A4 deliver pure
driving pleasure. At the same time, compared to the corresponding predecessors,
their fuel consumption dropped by more than 10 percent – for Audi, power and
efficiency always belong together. 
 
FSI: The supreme gasoline technology
 
The new A4 is being launched with two gasoline engines. The 3.2 FSI is a V6
with 265 hp. The newly developed four-cylinder 2.0 TFSI is available with 211 hp.
 
With these engines, Audi is once again extending its lead in engine design – using
the gasoline direct injection technology known as FSI, which is superior to
anything offered by the competition. With this technology, fuel is injected under
high pressure into the combustion chambers and at the same time intensely
swirled. The evaporation achieved in this way withdraws heat from the
combustion chambers, thus allowing for a high compression ratio that contributes
significantly to a highly efficient combustion process. FSI engines develop more
power and are more dynamic than conventional engines with fuel injection into
the intake pipes, yet they also make more economical use of fuel. 
 
Gasoline direct injection from Audi first demonstrated its potential for superior
performance in June 2001, when an engine featuring gasoline direct injection took
the Audi R8 sports prototype to overall victory in the Le Mans 24 Hours. In the
years that followed, the car entered 80 races and won 64 of them – evidence not
only of the power of the engines but also of the uncompromising commitment to
reliability and quality that is typical of the Audi attitude to both motorsport and
production. 
 
In keeping with its efficiency strategy, Audi has improved its FSI technology
further. In the V6 and the new two-liter four-cylinder engine, it is combined with
the innovative valve control technology known as Audi valvelift system. The
turbocharger on the four-cylinder combines the free-revving nature with high
torque – an exemplary blend.
 
The old turbo engine problem – the high combustion chamber temperatures and
the resulting knocking tendency – is resolved by using direct injection. This
allows Audi to achieve a higher compression ratio in its TFSI engines, which in
turn leads to improved thermodynamic efficiency.

Top gasoline engine: The 3.2 FSI 
 
The reassuring hum of the magnificent 3.2 FSI introduces the top-of-the-line
gasoline engine in the new Audi A4; it has been enhanced extensively. It is a
member of the modern Audi family of V engines, and is characterized, like all
Audi V6 units, by a 90-degree cylinder angle, compact dimensions and a low
weight, with a crankcase made from an aluminum-silicon alloy. This contributes
to the low overall weight of the new Audi A4 and its excellent axle-load
distribution. 
 
From a displacement of 3,197 cc, the 3.2 FSI develops 265 hp and delivers its
maximum torque of 243.40 lb-ft all the way from 3,000 to 5,000 rpm. Compared
with the previous model, which had a power output of 255 hp, fuel consumption
has been reduced.  The 3.2 FSI is available with six-speed Tiptronic; quattro
permanent all-wheel drive is standard as well in North America.
 
About half of the improvement in fuel consumption in the 3.2 FSI is due to the
Audi valvelift system (AVS). This new technology, which controls valve lift in
two stages, ensures excellent combustion chamber filling in all situations. It
regulates the amount of combustion air drawn into the engine by varying inlet
valve lift; in most cases the throttle butterfly can therefore remain fully open,
which largely eliminates undesirable throttling losses. The engine breathes freely,
develops more power and torque, but consumes less fuel.  Depending on load and
engine speed, an intake-pipe valve switches between long aspiration pathways for
excellent acceleration and short ones for peak power. 
 
A further advance in the 3.2 FSI are the timing chains for the camshafts; typical
for the Audi V engines, they operate in the back of the engines and take up less
space. 
 
The idler wheels and the shaft drive gears have a larger number of teeth, resulting
in quieter operation and reduced forces exerted on the chains. A similar effect is
achieved by the tri-oval, i.e., slightly triangular shape of the gear wheels. The oil
pump delivery volume has been reduced by 30 percent, and it now operates by
varying the volumetric flow according to actual demand. The net result is that
frictional engine losses have been reduced greatly. 
 
17/34
Inherited from the multiple winner: The new 2.0 TFSI
 
The base engine in the new Audi A4 is the 2.0 TFSI. The turbocharged four-
cylinder unit is the successor of the highly successful two-liter engine, which,
since 2005, has been voted ‘Engine of the Year’ three times in succession by an
international jury of journalists.
 
The new 2.0 TFSI’s most significant characteristics are an inlet camshaft that
adjusts variably through up to 60 degrees of crankshaft rotation and two balancer
shafts rotating with double the speed of the crankshaft in the crankcase. They
compensate the free second-order inertial forces and lead to refined running with
very low vibrations. 
 
The injection in the 2.0 TFSI itself demonstrates the innovative status of Audi
technology. The newly developed six-hole injectors deliver the fuel into the
combustion chambers with a pressure of 150 bar (2175.1 psi).  The result is
efficient combustion, enhanced by valves for vortexing the injection. A water-
cooled turbocharger increases the filling of the cylinders with air; optimized
turbine and compressor wheels have improved its reaction. The intercooler is a
new development as well, combining a high degree of efficiency with low weight
and small dimensions. 
 
The two-liter TFSI engine has the new Audi valvelift system. Unlike the 3.2 FSI,
here it facilitates variable control of the exhaust valves, which means that the
charge cycle can be drastically improved. The 2.0 TFSI in the Audi A4 thus
reaches its maximum torque of 258 lb-ft at an engine speed of just 1,500 rpm.
This technology continues to ensure an extremely quick and dynamic build-up of
torque, guaranteeing excellent agility and spontaneity.
 
The new Audi technology plays just as important a role in achieving high
efficiency as does the consistent improvement of all components to minimize
friction – with important advances made in the area of cylinders and connecting
rod bearing linings. The oil pump operates with volume-regulated delivery and
two-stage pressure control, which reduces fuel consumption.
 
The 2.0 TFSI delivers a sporty performance of 211 hp and a mighty 258 lb-ft of
torque, available from 1,500 to 4,200 rpm. This powerplant will be available in
North America with quattro drive and both manual and Tiptronic transmissions
18/34
for sedan (Tiptronic only in Avant).  Alternately, Audi delivers the A4 sedan 2.0
TFSI with front-wheel drive with the continuously variable multitronic.
 
In its fuel consumption, the new TFSI is amazingly frugal:  The high torque
allowed the developers to somewhat extend the transmission ratio – an important
factor in the efficiency concept.
 
The drivetrain
 
Intensive further development: Tiptronic 
 
The A4 3.2 FSI quattro and 2.0 TFSI quattro are optionally available with six-
speed Tiptronic. This classic automatic transmission, with the Sport program and
the additional manual-shift mode, has been thoroughly revised in design in the
transfer-case and torque-converter areas. 
 
The torque converter now is equipped with a novel form of two-stage torsional
damper that permits the lock-up clutch to remain engaged for long distances,
which boosts overall efficiency and reduces fuel consumption.
 
When the car is at a standstill, a controlled drive-off clutch disconnects the
transmission from the engine even if the selector lever remains in position D. As
soon as the driver releases the brakes, this clutch is engaged. 
 
In the new Audi A4, the Tiptronic transmission operates even more dynamically
than in the previous model; it reacts more rapidly and performs shifts much faster
without any penalties in terms of smoothness. The reasons for these improvements
are the improved layout of the oil passages used to fill the converter and more
powerful software for the Dynamic Shift Program (DSP).
 
For all the front-wheel-drive versions of the new A4 (Avant is quattro-only for
USA, Tiptronic only, 2.0 TFSI only with 211 hp), Audi offers the continuously
variable multitronic exclusively with the 2.0 TFSI powertrain. It combines the
advantages of manual transmission with those of torque-converter transmission
and, due to its both extremely comfortable and highly dynamic acceleration, it
provides sporty driving comfort. 
 
19/34
A great many improvements reduce its internal losses even further. By permitting
the engine to run continuously in its optimal operating range, multitronic allows
for an extremely frugal driving style.
 
The new variator also contributes to this high efficiency by allowing a wider
spread of transmission ratios – increased to 6.73 from the previous 6.25 between
the highest and lowest ratio. In the highest ratio the A4 accelerates powerfully,
whereas the lowest enables the engine’s fuel-saving potential to be fully utilized
by means of low engine speeds. Due to its reduced start-up ratio, the A4 moves
off powerfully from a standstill. With its adaptive control system, the transmission
varies its settings according to current driving style and road conditions.
 
The D mode provides classic, continuously variable transmission. The S sports
program operates with shorter ratios; when accelerating, the system shifts through
eight specific, pre-programmed ratios in succession – an impressively sporty
process. In one-touch mode, the third operating mode, the driver can actively shift
between the eight speeds, either using the selector lever or – optionally – using
shift paddles behind the steering wheel. 
 
Unsurpassed: quattro permanent all-wheel drive
 
The new Audi A4 2.0 TFSI and 3.2 FSI transmit their power to the road by way of
quattro permanent all-wheel drive; for the 2.0 TFSI, quattro technology is
standard for Avant and optional for the sedan for North America.  It delivers the
supreme capabilities that have become an Audi trademark – enhanced dynamics,
traction, safety, and directional stability.  The quattro versions of the new Audi A4
are supremely stable under all conditions. 
 
For the new Audi A4, the key element in the quattro driveline is a self-locking
center differential. It operates purely mechanically and reacts instantly to changes
in the driving situation, allowing the system to produce sporty and highly agile
driving dynamics. Under normal driving conditions, 40 percent of propulsion is
distributed to the front wheels and 60 percent to the rear wheels. Whenever
required, the self-locking center differential redirects most of the torque to the
axle with better traction. This means that when driving at the handling limits, the
new Audi A4 often does not require ESP or EDL to intervene, and there are also
significantly fewer brake ESP or EDL braking interventions.
 
20/34
The dynamic suspension 
 
The dynamic suspension on the new Audi A4 once again sets new standards,
combining precision and dynamism with a high level of stability and a supreme
sense of control. It has been entirely redesigned, with the suspension mounts,
steering, wheels and brakes developed for top performance and many aluminum
components used to reduce weight and thus keep unsprung mass to a minimum.
The innovative Audi drive select control system makes the driving experience
even more compelling. 
 
The new five-link front suspension greatly contributes to this technical advance.
By moving the differential to the front and the clutch back, the design engineers
were able to reposition the front axle 154 millimeters (6.06 inches) further
forward. Together with the relocation of the battery to the trunk, this solution
ensures an excellent front to rear axle-load balance. Even at a standstill, the new
Audi A4 displays its principal personality trait: the wide stance – 1,564 mm
(61.57 inches) at the front, 1,551 mm (61.06 inches) at the rear – and the large
wheels round off the picture of sporty dynamism. On the road, drivers will find
that the A4 is the sportiest of its competitors. It responds promptly and willingly
to steering movements, remains stable, and when the handling limits are reached
exhibits a slight understeering tendency which the driver can control easily. 
 
A solid base: The front suspension subframe
 
The largest chassis component of all is the subframe for engine and front
suspension. It is made of aluminum and rigidly bolted to the front end of the car.
Due to its high rigidity, steering forces are applied without lag. On the new Audi
A4, aluminum also is used for the bearing mount that links the upper suspension
control arms with the body and for the pivot bearing. 
 
The front suspension is made up of five links per wheel – a support link and a
control arm at the bottom and two control arms at the top. The fifth link – the
track rod – connects the steering box and the pivot bearing.  All these links are
made of forged aluminum, which ensures low unsprung weight, and provides
ultra-precise wheel control and a high level of crash safety. The tubular anti-roll
bar also helps to save weight.
 
21/34
The five-link suspension can handle longitudinal and lateral forces separately. In
the lateral direction, the bearings are rigid to promote sporty precision and high
cornering speeds. Longitudinally, however, they act with supple subtlety. In this
way, dynamism and ride comfort go hand in hand. 
 
Breakthrough: The low-mounted steering box
 
The steering system also has been thoroughly revised. The decisive step is the
repositioning of the steering box. It was high up and fairly far back on the
predecessor model – now it is far in front and placed low, on the subframe just
below the front axle. Since the steering impulse now is transmitted directly to the
wheels by the track rods, the steering response is very spontaneous. The steering
column is bolted to the cross-member below the windscreen and to the bearing
mount on the firewall, which further increases precision.
 
With an overall ratio of 16.1:1, the steering of the new A4 is sporty and direct. It
provides precise, well-differentiated feedback from the road, and the drive forces
and jolts are barely perceptible. The front suspension kinematics provide for
precise centering of the steering, which adds to the sense of steering accuracy
around the straight-ahead position.
 
The steering – a rack-and-pinion construction – was placed in an aluminum
housing. A controlled-output vane-type pump supplies the necessary hydraulic
energy. Unlike conventional power-steering pumps, which circulate a large
volume of oil internally, it delivers only as much fluid as needed at the time. This
reduction in energy consumption lowers the fuel consumption. 
 
For the V6 engine versions, Audi offers a further technology: They roll out of the
factory with speed-dependent servotronic steering, which adapts the amount of
steering support to the driving speed. When parking, this system provides for easy
steering, while at high speeds the support is decreased to ensure maximum
precision. 
 
Perfect ground contact: The rear suspension 
 
Guiding, self-steering action, cushioning – the rear suspension in the new Audi
A4 has many tasks to fulfill, and it does so magnificently. Its design is based on
the toe-controlled trapezoidal layout chosen for the larger model lines, combining
22/34
compact dimensions with excellent ride quality and comfort. The kinematics,
however, were newly developed from the ground up. This also led to the benefit
of greatly limited braking sway, thus further enhancing the impression of sporty
dynamism.
 
The backbone of the rear suspension is formed by a torsion-proof and non-flexing
subframe, welded together from two longitudinal and two lateral tubes of high-
strength steel. This subframe is attached to the bodyshell by four rubber mounts;
these are especially firm laterally for dynamic handling, but they are softer in the
vertical and longitudinal directions for better ride comfort. All suspension control
arms are acoustically decoupled from the axle subframe by means of elastomer
bushings. 
 
If sporty handling is to be combined with a high degree of comfort, the unsprung
masses must be kept as low as possible. The two trapezoidal links are cast in
warm-hardened aluminum, andthe wheel carriers are of chill-cast aluminum. The
upper control arms and the track rods are of forged aluminum. The tubular anti-
roll bar also combines low weight with high rigidity.
 
The compact design of the trapezoidal-link suspension has notable packaging
advantages: the cargo floor in the new Audi A4 Avant is low and flat, with a load-
through width of exactly one meter. There are only minor differences between the
axles in the front-wheel-drive and quattro models, such as the subframes, which
for the quattro models have an additional provision for rear-wheel drive. 
 
The suspension springs no longer act on the trapezoidal links as on the previous
model, but directly on the wheel arms. In this way they can react with more
subtlety while being able to extend the spring travel 20 mm (0.79 inches).
Separate spring and shock absorber mountings improve initial response. The
suspension bushings use special rubber mixtures that further enhance ride comfort. 
 
As an option, Audi also supplies the new A4 with sports suspension. It has firmer
springs and shock absorbers and reduces the body’s ride height by 20 mm (0.79
inches).

The joy of driving in a new dimension: Audi drive select 
 
Audi drive select represents a breakthrough in the midsize class, which propels
the A4 into new dimensions. The system integrates all technical components that
govern the driving experience; using a button in the cockpit, the driver can
determine how sportily or comfortably the system should operate.
 
Audi drive select will be available in one version in the U.S.A., integrating all
three systems of engine/transmission mapping, steering, and suspension controls.
The engine’s throttle response, the speed-dependent servotronic power assistance
and the Tiptronic shift points all can be programmed into three main fields. The
‘comfort’ mode is ideal for relaxed driving on long journeys or over poor road
surfaces; ‘auto’ is the most balanced setting and ‘dynamic’ is the tight, firm stage
where the chassis of the new A4 can demonstrate its package of power fully.
 
Changes between the modes are made using two arrow buttons on the center
console. All such changes are performed safely and smoothly. The driver can
clearly discern them but is not distracted. The driver has a fourth mode available,
known as ‘individual.’ Within practical limits, this personal profile can be
assembled from a wealth of possible settings. With Audi drive select, the new A4
is up to four cars in one. 
 
Continuous control: The CDC shock absorbers 
 
The Audi drive select is augmented by yet another innovative technology –
electronically governed shock absorbers. The central element is a new high-
performance control unit. The computer continuously analyzes the signals from
14 sensors, and it calculates the current for the electronically governed shock
absorbers at each individual wheel 1000 times per second. 
 
The so-called CDC (continuous damping control) shock absorbers are gas-filled
hydraulic shock absorbers whose operation can be varied continuously. An
electromagnetically triggered valve regulates the flow of hydraulic fluid between
the inner and outer shock-absorber tubes. A smaller flow cross-section makes the
damping characteristic firmer, while a larger one makes it softer. 
 
24/34
Within the mode the driver has selected via Audi drive select, the control unit
employs adaptive characteristics, i.e., it adapts to match the driver’s style and the
road conditions.
 
Every single driving situation requires a specific damping force. In order to keep
body movements as low as possible, for example, a high damping force is
required. When driving over ridges, low forces are needed, so that when
accelerating the jolts are felt as little as possible by the passengers. For good
ground contact and minimal wheel load fluctuations, a medium level of damping
force is required, as the wheel must not be damped too much or too little. The
control unit selects the optimal damping force for every driving situation. The
CDC shock absorbers are joined with sporty springs, which lower the body by 
20 mm (0.79 inches).
 
A new level of high-tech: Audi dynamic steering
 
Yet another innovative technology is available in Audi drive select: Audi dynamic
steering. With this feature, Audi is opening a new chapter in the history of the
automobile. At the heart of the system is a superposition gear that operates with
no play and modifies the steering ratio in response to vehicle speed. When
cornering at the handling limits, the dynamic steering system stabilizes the A4 by
intervening instantly with small steering maneuvers. 
 
The superposition gear consists of a wave gear (also referred to as a “harmonic
drive”) integrated into the steering column and powered by an electric motor.
Harmonic drives have been used with a great deal of success in the robotics and
aerospace industries. A harmonic drive was used for the first time in space in
1971 on Apollo 15. It was part of the single-wheel drive of the lunar rover that
explored the surface of the moon. In 1997 the drive traveled to Mars as part of the
Pathfinder mission, in which it was part of the “Sojourner” expedition vehicle.
The drive also had a role to play when the Hubble space telescope was launched
in 1990. 
 
Tested in the proving ground of outer space, the strengths of harmonic drive
technology extend to a number of important areas. The system is extremely
compact and lightweight with a high level of torsional rigidity. Its lack of play
allows it to operate with extremely high precision and very little friction, while
transmitting immense torque with a high degree of efficiency. Audi is the very
25/34
first manufacturer to take all of these brilliant characteristics – that together far
exceed the solutions offered by the competition – and apply them to automotive
technology. 
 
Audi dynamic steering can vary its steering ratio in response to both the vehicle
speed and the Audi drive select mode in use. Transitions are continuous and
imperceptible. System involvement is very direct when parking. Drivers can cover
the entire steering range in just two turns of the wheel – a maneuver made nearly
effortless, thanks to a high level of power assist. 
 
At moderate highway speeds, the system becomes less direct and provides less
power assist. At top speeds, an indirect steering ratio and low level of power assist
make it easy to keep the vehicle in its lane. 
 
Safety and driving pleasure: The countersteering effect of dynamic steering 
 
ESP and dynamic steering work together closely to improve handling
characteristics and vehicle safety. Dynamic steering supports the stability program,
because it can perform a countersteering maneuver in considerably less time than
the brake system needs to generate braking pressure. These rapid maneuvers
eliminate the need for frequent braking and generate extra smoothness and
dynamism. Despite their enormous effect, drivers generally do not notice the
corrections. 
 
Fishtailing – a classic critical situation – is triggered by counterforces produced in
response to sudden evasive action. Audi dynamic steering can correct for small to
medium fishtailing by countersteering. Braking is not required unless fishtailing is
severe, and even then it largely serves only to provide damping. 
 
Dynamic steering also provides assistance for understeering (when the car slides
toward the outside of a curve). Steering briefly becomes less direct, very likely
preventing the driver from steering beyond where the tires have adequate contact
with the road surface. This function is available exclusively from Audi. None of
our competitors offer it. 
 
Braking on surfaces with different coefficients of friction (known as μ-split
braking) is another situation that can be difficult to manage. Higher braking forces
pull the vehicle toward the side with the greater coefficient of friction. Audi
26/34
dynamic steering in the new A4 resolves this problem – largely on its own. Just
about all the driver needs to do is turn the steering wheel in the desired direction
of travel. 
 
Uncompromising: The brakes 
 
A braking system designed for uncompromising performance was a point of
honor for the sportiest midsize wagon. The new Audi A4 comes with completely
redesigned brakes that have grown by an order of magnitude over its predecessor.
The deceleration potential and precision of these brakes are improved greatly. 
The driver senses a brake pedal whose response is both firm and precise, allowing
the perfect amount pressure with very little effort. 
 
The A4 leaves the factory with minimum17-inch wheels (or larger) in U.S.A. The
brake pads are around 20 percent larger; the new high-performance pads combine
high coefficients of friction with very little fading.
 
The internally ventilated front disks were trimmed down for maximum heat
dissipation – a feat accomplished by ideal integration of frictional surfaces and a
new design that manages without traditional cooling channels. The two halves of
the disc are joined by hundreds of small metal cubes that can disperse a great deal
of hot air quickly. 
 
The V6 versions of the new Audi A4 feature larger front brake disks (diameter:
320 mm/12.60 in). The brake calipers have a composite design based on the
floating-caliper concept. High-strength spheroidal graphite iron is used where a
high level of rigidity is required. The piston housing – bolted into place and made
of aluminum – conducts heat admirably. Taken together, these features yield
brake calipers that are both lightweight and extremely rigid. 
 
Other areas where Audi has saved weight include the brake disks (up to two
kilograms (4.41 lb) when installed) and aluminum cover plates (1 kg/2.20 lb).
These reductions further reduce the weight of unsprung components, improving
handling and comfort. An additional benefit for customers is the design of the
calipers and wheel rims. When a car is brought in for servicing, mechanics can
measure the strength remaining in the brake pads without even having to remove
the wheels. 
27/34
New design: ESP
 
ESP plays a major role in the agile, sporty impression made by the new Audi 
A4. This new generation of the drive stabilization system operates on the basis of
highly exact hydraulic valves that manage braking pressure with unusual precision,
regulating the brakes with no detectable vibrations and without the usual,
notorious shuddering. 
 
The operating concept also is new. ESP still can be completely switched off by
pressing and holding a button. In this case, ESP is deactivated in all operating
situations. The only systems that remain active are EDL and ABS, as well as
support of μ split steering stabilization by the optional dynamic steering system, to
make it easy for the driver to control the situation. In the instrument cluster, the
message “ESP switched off” appears. If the button is pressed a second time, ESP
is switched back on again.
 
Now, however, a second, lower level is available. Briefly pressing the ESP button
at speeds below 100 km/h (62.14 mph) allows the driver to deactivate anti-slip
control, which essentially switches off engine involvement and applies the brakes
at a slightly reduced level. The stabilizing steering maneuvers provided by the
dynamic steering system are not affected. A monitor light switches on in the
cockpit as a safety feature. 
 
“ASR-off” mode on the A4 with front-wheel drive is a huge advantage when
driving with snow chains. It allows the wheels to spin – which can often be
helpful – without having to switch ESP off completely. At speeds exceeding
70 km/h (43.50 mph), front-wheel-drive models automatically switch back to full
ESP mode. In quattro models, “ASR-off” mode remains activated at all speeds. In
the latter case, this mode works with the vehicle’s power distribution (which
favors the tail) to help experienced drivers when drifting on surfaces with low
coefficients of friction.
 
ESP in the new Audi A4 also has further capabilities. On wet surfaces, it wipes
the film of water off the brake discs with brief, imperceptible applications of the
brake pads. (Audi was the first to offer this feature within its segment on the
previous generation A4.)  ESP also compensates for the fading effect that can
arise during repeated emergency stops. 
 
28/34
Audi engineers designed ABS in close cooperation with the developers of the
brand of tires used in the original equipment. The brake control strategy was
finely tuned to allow the new A4 to take full advantage of the frictional potential
of its tires. 
 
The assistance systems 
 
Calmer, safer driving – the innovative assistance systems on board the new Audi
A4 help to make your trip more relaxed. Audi is the engine driving progress in
this area, equipping the Avant upon request with high-tech systems taken directly
from the luxury class. These systems regulate the distance to the preceding car,
help the driver change lanes, and assist with parking. 
 
Over the past decades, passive and active safety systems have significantly
reduced the number of accidents and lessened their effects. And Audi is taking
this progress to new levels. Its novel support technologies can, like human beings,
register aspects of a car’s surroundings and use that information to make correct
decisions and take appropriate action. Audi systems make for a relaxed, safe drive.
Although responsibility still rests with the driver, these systems support the
driver’s ability to concentrate by alleviating some of the stress. 
 
ACC maintains the distance
 
Another assistance system that comes from the luxury car class is radar-supported
automatic cruise control (ACC). It not only keeps the car traveling at any chosen
speed from 30 to 200 kilometers per hour (18.64 to 124.27 mph), but also
maintains a safe distance from the vehicle in front. The system reacts to vehicles
up to 180 meters (590.55 feet) away: its radar sensor detects any change in the
distance the car is maintaining from the vehicle ahead.
 
If the driver wants to overtake quickly, ACC is overridden by pressing the
accelerator down hard, but it stays active and returns to the previously chosen
road speed and distance from the vehicle in front. If the brake pedal is pressed
down, ACC is switched off completely, and then has to be selected again at the
control lever (Reset). The last speed setting before it was switched off is
recovered.
 
29/34
Doppler effect and signal transmission/reflection time: how ACC gets its
measurements
 
The radar sensor is in a casing with a plastic lens that is installed in the decorative
grill at the right of the single-frame radiator grill. The sensor scans an angle of
eight degrees each side of its centerline, and it has a range of about 180 meters
(590.55 feet). The four radar transceivers operate in the 76.5 Gigahertz frequency
band, which is licensed for radio transmissions. The transmission is of the
Frequency Modulated Continuous Wave type. The measured values that the
system needs are the frequency differences between the transmitted radar signal
and the one reflected back from the vehicle ahead. Using the Doppler effect and
the time it takes the signal to return, the speed of the vehicle in front and how far
away it is both can be calculated. The preceding vehicle’s angle from the sensor’s
center axis also can be determined by comparing the signals received at the four
antennas. But before the relevant vehicle can be isolated from the other objects
detected by the sensors, the car’s own path (the ‘tunnel’ within which it is
moving) has to be determined as well. 
 
This ‘tunnel’ is computed from signals received from the ESP yaw rate sensor and
the steering angle sensor and from radar information derived from road
boundaries (for instance crash barriers) and the movements of other vehicles. The
system is integrated into the CAN network that extends through the whole car; it
can, therefore, communicate with the other control units (for example engine
management, transmission or brakes) within a few thousandths of a second.
 
Controls and displays
 
The driver chooses a preferred speed according to the scale markings on the
speedometer – in 5 km/h (3.11 mph) steps from 30 to 80 km/h (18.64 to 
49.71 mph), or 10 km/h (6.21 mph) steps at higher speeds. The selected speed is
shown by light-emitting diodes on the speedometer scale; the system’s status
(on/off – vehicle detected) can be seen on the center display. You can select the
time lapse between the vehicle in front and your own car in four stages, between 1
and 2.3 seconds; the chosen value can be seen in the driver information system.
The system’s dynamic response can be varied by choosing one of three drive
programs at the MMI (dynamic/standard/comfort). The system then accelerates
30/34
the car or slows it down at the dynamic rate chosen by the driver. The ‘comfort’
setting is limited to a maximum speed reduction rate of 3 m/s2.
 
Lane monitoring and collision warning – Audi braking guard
 
The Audi braking guard is an extra safety function that is part of ACC. If there is
a risk of colliding with the vehicle in front, the system warns the driver in two
stages: at first with an ‘early warning’ gong accompanied by a visual signal on the
instrument panel. At this point the ESP increases hydraulic pressure in the brake
system as a safety precaution, so that if the driver brakes, full stopping power is
available immediately.
 
If the driver fails to respond and the risk is still present, the system builds up
pressure rapidly in the brake circuits. This sudden braking action only slows the
car down slightly, but nonetheless causes it to suffer a noticeable jolt.
 
The aim of this jolt, which Audi has investigated in an extensive series of tests
and found to be very effective, is to draw the driver’s attention to the need for
urgent action. If the driver now applies the brakes, full braking power is available
without any delay, and even hesitant pressure on the brake pedal causes the
hydraulic brake assistant (HBA) to make a full brake application.
 
The Audi braking guard is still monitoring the situation when ACC is deactivated.
On the other hand, either the early warning signal or the complete Audi braking
guard function can be switched off at the MMI, to comply with the Audi policy of
always leaving the driver in control of the situation to the extent that they may
wish.
 
Looking back and to the side: Audi side assist 
 
Audi side assist also makes use of intelligent radar technology. The system was
designed to warn drivers of dangerous situations when changing lanes. Two radar
sensors located in the rear bumper operate at 24 GHz, monitoring a space of up to
50 meters (164.04 feet) in width to the side and rear of the new Audi A4. A high-
speed computer analyzes the data. 
 
31/34
Any time another vehicle going roughly the same speed moves into the blind spot
or a vehicle approaches rapidly from behind, a yellow LED display lights up in
the housing of either the left or right exterior mirror and remains lit. This warning
signal is designed to be unobtrusive so as not to disturb. Drivers do not see it
unless they are looking directly in the mirror. 
 
The LEDs brighten and begin flashing rapidly for roughly one second if, despite
the initial warning signal, the driver signals a lane change. A series of tests
conducted by Audi has shown that this flashing light is nearly impossible to
overlook, because the human eye is extremely sensitive to changes in contrast in
its peripheral vision.
 
This visual display is located on the inner surface of the mirror housing so that the
driver is virtually the only one who can see it. The brightness of the display adapts
to the surrounding light and can also be adjusted from the MMI operating terminal.
The system is activated at speeds greater than 60 km/h (37.28 mph) and can be
deactivated by pressing a button. 
 
The APS systems: parking made easy 
 
Audi has two available parking assistance systems for the new A4 that make
parking easy. The familiar, successful Audi parking system (APS) uses an audible
signal to indicate distance to the rear.   Audi parking system with camera
integrates a rearview camera display. Incorporated into the trunk lid and
extremely sensitive to light, this camera contains a fish-eye lens providing a
generous, 130-degree view of the area behind the car. The images generated by
this camera are equalized and displayed on the MMI operating system monitor. 
 
The system also guides the driver with a variety of suggested lines and fields.  In
addition to real-time mode, APS advanced also offers the classic features of a
visual/acoustic parking aid, aided by ultrasound sensing technology. 
 
Multimedia systems
 
The Audi A4 also is raising the bar in its class in one of the most exciting of
cutting-edge technologies – multimedia. It is being launched with an attractive
array of communication and entertainment technologies. 
 
32/34
The AMI (Audi Music Interface) makes it possible to hook up a fourth generation
iPod, while a separate adapter cable allows users to connect any audio player of
their choice having a USB 2.0 interface. The AMI software is modular in design,
with individually stored drivers responsible for communicating with players and
reading their protocols. New driver updates can be installed quickly and easily
anytime a new player comes onto the market. 
 
The concert and symphony radios operate with a dual tuner: two tuners process
signals before these proceed to a digital processor. One of the tuners processes
music while the other works in the background, scanning for stations that are clear
enough to receive. This technology can pull in even the weakest of stations,
because it can combine its receivers in such a way that the two antennas of the 
A4 operate like a beam antenna. 
 
MMI: Navigation system and luxury user interface 
 
North American customers have an optional navigation system that offers a dual
tuner and seven-inch color display. Navigation information is provided by a fast,
powerful DVD drive. An AMI (Audi music interface) interface for full iPod
integration within the MMI system is available. 
 
Audi offers two excellent sound systems for its concert and symphony radio
systems: 180 watts of system power and 10 speakers give the Audi sound system
impressive, well-balanced surround sound. In addition to the eight standard
speakers, this system also includes a center speaker in the instrument panel and a
260 mm (10.23 inch) subwoofer in the rear shelf. An extensive variety of settings
are available for customizing the systems. 
 
Pure delight: The Bang & Olufsen sound system 
 
The pinnacle of sound system technology and acoustics, Bang & Olufsen – once
available only in the A8 luxury sedan – now can bring pure listening pleasure to
A4 drivers. Brilliant sound quality, faithful resolution, precise staging and a broad,
finely differentiated frequency spectrum – the product of the Danish sound
specialists will meet every demand. 
 
33/34
Audi and Bang & Olufsen have come together as partners in pursuit of the same
objectives. Both companies place a premium on the most modern technology
available, intuitive operation and classic, technoid design. Furthermore, both
manufacturers are experts when it comes to materials, quality craftsmanship and
working with aluminum (which Bang & Olufsen uses in its speaker covers). 
 
The heart of the Bang & Olufsen sound system is a 505W amplifier that digitally
processes signals according to a proprietary surround-sound algorithm,
guaranteeing pure listening satisfaction for everyone in the car. The numerous
settings options include four different sound modes. Included in the system is a
microphone for analyzing the noise level within the A4; the system then changes
the frequency, adapting the signal output to ambient sound conditions. 
 
The Bang & Olufsen sound system includes 10 active channels with 14 speakers.
Two three-way systems are found in the front (each including one speaker in the
door, mirror triangle and instrument panel); two speakers are located in each rear
door. The acoustic choreography is rounded out by a center speaker in the
instrument panel, a 260 mm (10.23 inch) subwoofer in the spare wheel well and
two surround-sound speakers. 
 
Warranty
The Audi A4 will be backed by a new vehicle limited warranty that includes:
•       Four-year/50,000 mile limited new vehicle warranty
•       12-year limited warranty against corrosion perforation
•       24-hour Roadside Assistance for four years

Cylinder head Aluminum alloy
Valve train / intake Audi valvelift system 2-stage intake valve lift;  Variable valve timing
Cooling system Water-cooled, thermostatically controlled radiator fan
Lubrication system Gear pump, pressurized, full flow with oil cooler
Fuel injection: FSI Direct Injection -A common rail high-pressure injection system with a newly developed single-piston high-pressure pump operating on demand
ensures exactly the right amount of fuel, delivering precisely the volume required for building up operating pressure between
30 and 110 bar.
-The intake tract, also comprising the two-stage variable intake manifold, moving charge-movement flaps provide the necessary
tumble effect, swirling the induced air around depending on operating point.  In order to achieve the high specific power and
torque values, a new combustion process has been developed.  This has the potential for worldwide application and for operation
on the fuel grade RON 95/91.  Together with the optimum geometry of the combustion chambers and the dosage of fuel injected
with supreme accuracy down to the last millisecond, this allows a significant increase in compression:
-While conventional production engines generally have a compression ratio of now more than 10.5 : 1, the compression ratio on
Audi's 3.2 FSI power unit is 12.5 : 1 - a record on production cars and the essential prerequisite for the new engine's high standard
of efficiency.
