The Audi A8
Audi has launched the next generation of the A8 - the sportiest
sedan of the luxury class sets new standards. Its elegantly styled body
with the Audi Space Frame (ASF) is aluminum, the engines are powerful
and highly efficient, and the power transmission and running gear
combine dynamics with convenience. The new flagship’s generously
designed interior captivates with its luxurious equipment, newly
developed control system MMI and the excellent quality of its
workmanship. Innovative assistance systems lend even more confidence to
driving.
Design
Audi design is always fascinating in its complex intelligence. The
outer skin of the new A8 conveys homogeneity, as if modeled from a full
volume. A coupé-like roof line lets the silhouette flow; sculptured
surfaces conveying calmness and prestige contrast with sharp lines. The
new A8 underscores the leading position maintained by Audi in the field
of automotive design. Representing the cutting edge in many innovative
technologies, the A8 indicates this role through new and progressive
design elements.
5137 mm (16.85 ft) in length, with a 2992 mm (9.82 ft) wheelbase,
1949 mm (6.39 ft) in width and 1460 mm (4.79 ft) in height – the new
luxury sedan is generously proportioned. The Audi A8 significantly
exceeds in length and width both its predecessor and its competitors.
Its height, however, remains below that of its immediate rivals in
Germany – the proportions follow the dynamic line.
The A8 displays its single-frame radiator grille like a proud
coat of arms. Framed by a chrome edge, the grille presents a new design
– sculptured, three- dimensional and rich in details. With angular
upper corners, it is neatly integrated in the front section, while the
prominent, horizontal chrome braces emphasize the vehicle width.
The Audi A8 looks out on the world through newly designed
headlights – with xenon plus units and the innovative full LED
headlights, a technology Audi was the first to introduce worldwide in
the R8 high-performance sports car. The adaptive light system augments
the xenon plus units – it controls the swiveling modules so that they
always provide the perfect lighting for intersections, the city,
country roads and highways. The new all-weather light integrated into
the headlights replaces the fog lights. Their traditional location in
the air intakes is now occupied by the radar sensors of the optional
adaptive cruise control with stop & go function.
A technological breakthrough from Audi is the networking of the
headlight control unit with the optional MMI navigation plus. The
navigation system analyzes the route ahead and relays the data to the
light computer to activate highway lighting with its extended range
while still on the ramp to the highway, for example. Before entering an
intersection, the system activates the cornering light, which provides
wider-angle illumination and thus enhances safety.
High-end technology: the full LED headlights
The high-end solution on board the new A8 is the full LED
headlights. They give the big sedan an unmistakable appearance even in
daylight and even more so after the fall of darkness. Their
revolutionary optics mean a departure from the large, tubular light
modules commonly used today.
The low beams comprise ten individual modules forming an arc
situated below the wing-shaped chrome contour known as the “wing.” Just
below this is another arc of 22 white and 22 yellow LEDs for the
daytime running lights and the turn signals. Their thick wall
technology makes them appear from the outside as homogenous, continuous
strips of light.
Located above the wing are the high beams, whose light is
generated by two powerful four-chip LEDs and a free surface reflector
system. An assistant switches between the high and low beams, and
additional high-power LEDs generate the highway light and cornering
light. A separate fan and heat sink moderate the system’s temperature.
The full LED headlights offer a number of functional advantages in
everyday situations. With a color temperature of 5,500 Kelvin, their
light resembles daylight and thus is much less tiring to the eyes. They
also offer efficiency advantages. The low beams, for example, consume
only 40 watts per unit, a bit less than the already highly efficient
xenon plus headlights.
The side view of the new Audi A8 also gives the image of
concentrated and forward-thrusting power. Typically for the Audi line,
the vehicle line makes up two-thirds of the height, with the remaining
third falling to the greenhouse. From the single-frame grill Audi's
characteristic Tornado line runs as a light edge just beneath the
window sill. The line continues close above the wheel arches, giving
the A8 a powerful appearance on the road.
The surfaces below the Tornado line interpret the interplay of
light and shadow, of convexity and concavity, and are statement of
seriousness and timeless elegance. Proceeding downwards, the surfaces
are framed by the rising dynamic line running above the side sills.
Large wheels – from 17 to 21 inches in diameter – fill the wheel arches
pulled out wide.
At the rear the separation edge gives an impression of sleekness,
which further reinforces the impressively sculptured surfaces. A chrome
strip underlines the width of the sedan, terminating in a diffuser.
The tail lights also produce an appearance both three-dimensional
and striking – and typically Audi. They, too, use LED technology with
72 light-emitting diodes per unit. Chip-on-board LEDs, which can be
packed tightly together with high precision, are used in many areas due
to the limited amount of space available.
The tail lights, which consume only 9 watts per unit, form a
trapezoidal contour that appears as an even, homogenous strip. Its
upper segment is a light guide – a plastic tube; the lower section is a
reflective, textured free-form surface. It is thicker than the upper
segment to optically lower the center of gravity of the A8's back end.
The turn signal is a horizontal line. The five-segment brake light is
located inside the trapezoid.
Body
Big, strong, safe and yet amazingly lightweight – the aluminum
body once again sets new standards. Its low weight is a key factor for
the outstanding driving dynamics, exemplary efficiency and very good
comfort of the new A8. Audi, the lightweight design pioneer of the
automotive industry, again demonstrates its leadership role.
Fifteen years ago the four rings brand introduced the technology
of the Audi Space Frame (ASF) into production – with the first A8
generation. ASF has proven its merit outstandingly; and now Audi is
again using it in a much more advanced form. In its basic design the
ASF body brings a latticed framework to mind. Its skeleton comprises
extruded sections and pressure diecast parts of aluminum. The aluminum
panels – such as the roof panels and the side panels – are joined by
friction connections.
Depending on their tasks, the components of the ASF body fully
differ in shape and cross-sectional area. For example, the A-pillar
nodes of the new A8 – one of 25 castings in the body – interconnect the
longitudinal member, the sill, the omega cross-member, the windshield
crossmember, the roof frame and the suspension strut mount. The lateral
roof frame, on the other hand, is formed by a single extruded section;
its cross-section changes flexibly from the A-pillar to the C-pillar.
Audi has substantially increased the strength of the
higher-strength body components in the new A8, thereby significantly
reducing both material thickness and weight.
One of the keys for this is a novel composite material for the
aluminum panels. The use of this new, high-strength aluminum alloy
alone enabled a weight saving of 6.5 kilograms (14.33 lb).
High stiffness, low vibrations
Besides the low weight, the ASF body of the A8 has many other
strengths. The static torsional stiffness has increased by 25 percent
compared with the predecessor, already a leader in the field; it forms
the basis for the precise, dynamic handling. In terms of lightweight
quality — the relationship between weight, torsional stiffness and size
— the body achieved an improvement of 20 percent. The ASF principle
ensures comfortably low levels of vibrations and impressive quietness
on board for that typical Audi feeling.
The new A8 glides calmly, sleekly and quietly through the wind.
The 4.2 FSI version has a drag coefficient of only 0.26, with the
frontal area measuring 2.41 m2 (25.94 square ft). Low lift coefficients
at the front and rear axles ensure confident stability at highway
speeds. The luxury sedan also once again leads its class in wind noise
comfort.
Audi regards the development of a new vehicle as a holistic
mission. The overall energy balance sheet covering the entire vehicle
life reveals the new A8 achieves better results than its predecessor
with respect to all important environmental criteria, including CO2
emissions. The crucial factor is the phase of use, where in particular
the new, highly efficient engines play a positive role. Aluminum is
also superior to steel as a body material with respect to CO2 thanks to
its excellent recycling properties.
Interior
The interior of the new Audi A8 is a wellness lounge for the
senses. With its elegant styling and quality of workmanship on the
craftsman level, the interior is deeply rooted in the philosophy of the
four rings brand. In the cut it is much wider, more airy and spacious
than its predecessor. Its salient element is the “wrap- around” – a
circumferential curve forming an elegant beltline as on a yacht. The
large curve integrates the sleek and low instrument panel. Its neat
& tidy front is shaped like a gentle wave.
The Audi brand’s clear and intuitive operating philosophy reaches
new heights in the A8. The large, round instruments are clearly
delineated. The driver information system (DIS), which serves as a
fully fledged information and control center, has a new layout. Its
center display has increased to a 7-inch diagonal, showing all
functions according to an easily understandable concept. It is
operated at the equally improved multifunction steering wheel.
The center tunnel: perfect control console
The center tunnel in the new A8 is wide and evenly inclined. As an
ergonomically ideal control console, it contains the control panel for
the automatic air conditioning and the terminal of the MMI control and
multimedia system, now in a new version. It forms a clearly organized
touch & feel arrangement of three zones, one of which is reserved
for audio. Operation is totally stress-free: The driver’s wrist on the
selector lever of the 8-speed tiptronic, asymmetrically located on the
center tunnel, leaving the hand at ease to touch and turn switches.
In standby mode, the monitor of the MMI system is recessed in the
instrument panel. Switched on, it moves upwards in an elegant curve,
nicely setting the scene for the system start. The large monitor with
its 8-inch diagonal is extremely flat. Its display area is divided into
three information zones, while the menu control system follows a
further improved and intuitive logic. All topics are presented in
elegant, three-dimensional graphics.
The A8 also sets the bar at a new height in the quality of
workmanship, another big domain of Audi. The combination of
highest-quality materials and their precise implementation make the
interior a sensuous experience. The large controls and buttons are
optionally available with aluminum surfaces and click easily and
precisely like clockwork. Many switches gleam in high-gloss black, and
all frequently used parts are covered by a new kind of top coat making
them extremely scratch-resistant.
The large decorative inlays each consist of two parts – a highly
elegant solution. The bottom elements come in standard highly polished
black, the top ones in walnut brown, while the whole is accentuated by
fine chrome strips. Brushed aluminum and fine woods are optionally
available from Audi. All components feature uncompromisingly precise
workmanship and minimal gaps.
Audi offers five basic colors for the interior, and three shades
for the roof lining. The selection of coverings ranges to natural
leather, which is especially soft and breathable. Passionate
individualists can choose from two Audi design selections in special
colors that integrate many luxurious equipment features. Audi also
offers several leather packages, an Alcantara package and the extended
aluminum look in the interior.
Highly emotional: the orchestration of light
At dark another high-end feature comes into play – the new ambient
light. White LEDs add a few subtle highlights to the interior. The
ambient light package is an emotional overall orchestration, providing
effective illumination and making the center console seem to float.
Many LEDs here are two-colored or three-colored – the color schemes of
ivory, polar and ruby can be selected at the MMI. In other words, the
same LEDs can change between two and three colors.
The many sophisticated solutions in the new A8 include the
start-stop button, which allows the driver to start the engine while
leaving the key in his or her pocket.
The automatic air conditioning system regulates the interior
climate in two zones, and optionally in four. Three climate styles are
available – gentle, medium and strong – which also change the type of
air flow. For winter a fourth variant is available that heats the
footwell more intensively.
The standard front seats feature 12-way electric adjustment. The
comfort seats offer even more luxury with their 22-way adjustability,
also incorporating the sides of the seats. Audi also offers optional
seats with a sporty look and top-stitched diamond patterns.
Three-staged ventilation is offered in addition to the heating. Another
luxury extra is the pneumatic massage, in which twin air chambers
pulsate in the backrest – the driver and front passenger can regulate
them in five programs, with the intensity graduated in three stages.
As a large, luxurious touring sedan the A8 also treats its rear
passengers on a first-class level. On request, Audi even provides the
rear bench with versatile electric adjustment of the outside seats; a
memory feature is on board as is adjustability of the front passenger
seat from the rear. Seat heating, electric blinds and the four-zone
automatic air conditioning together with a separate rear control panel
round off the package. Ventilation and a massage function are also
available.
The new A8 provides 510 liters of large luggage space, cut very
wide. Four golf bags can be fitted crosswise; smaller objects are
accommodated in the side compartments. After unlocking, the gate
automatically swings up. The standard (in the U.S.) luggage compartment
includes a net, two hooks for bags, an umbrella holder and a 12 V
outlet. Load-through capability with ski bag and an electric tailgate
are also available.
Engines
Superior power and high efficiency – the new A8 makes its debut on
the market with a strong V8 engine. With 372 hp, they never fail to
impress with their superior power and mighty but discreet propulsion.
All engines feature direct fuel injection, and consume 15 percent less
fuel than their respective predecessors.
The engine in the A8 has intelligent elements from Audi’s modular
efficiency system on board. During deceleration the recuperation system
converts the kinetic energy to electric power, which is buffered in the
battery. In the innovative thermal management a computer monitors
numerous actuators for the ideal distribution of the heat flows between
the engine, transmission and interior in any situation. After the cold
start the engine is temporarily fully uncoupled from the cooling
circuit, considerably shortening the warm-up phase with its high loss
of friction.
The 4.2 FSI draws 273 kW (372 hp) of power from 4,163 cm3
displacement, generating its maximum of 445 Nm (328.22 lb-ft) torque at
3,500 rpm. It accelerates the A8 from zero to 100 km/h in 5.7 seconds,
with the propulsion ending (as in all engine variants) at the
electronically controlled speed of 250 km/h (155.34 mph).
The most important reason for this enhanced power is the reduction
of internal friction, especially in the chain drive for the camshafts
and auxiliaries. The controlled oil pump with changeover between two
pressure stages operates with high efficiency. Like all gasoline
engines from Audi, the V8 has FSI direct injection. It allows a high
compression of 12.5:1, for increased power and efficiency.
Drivetrain
The new Audi A8 offers the utmost superiority also in power
transmission. A new, electronically controlled 8-speed tiptronic system
and quattro permanent all- wheel drive from the production line. On
request, Audi also installs the dynamic sport differential.
The 8-speed tiptronic is a totally newly developed automatic
transmission. Its great strength lies in the high overall gear ratio of
7.0:1 between the shortest and longest gear ratio, reducing the fuel
consumption by about six percent. Starting off, the A8 accelerates
dynamically, rolling along highways with low, consumption-reducing
revs. All gear changes are nearly unnoticeably soft and smooth, very
fast and highly flexible.
The 8-speed tiptronic achieves a high level of efficiency. One of
the factors behind this is the highly efficient pump for supplying oil,
another the heating of the oil by the coolant following a cold start,
for lowering frictional loss.
The dynamic shift program (DSP) that controls the transmission
features the automatic operating modes D and S. A pioneering innovation
from Audi is its networking with the detailed route data supplied by
the optional MMI navigation plus system. By means of this data the DSP
incorporates upcoming curves in its gearshift strategy – it avoids
unnecessary gear changes on narrow roads, for example.
The new selector lever on the center tunnel is for selecting
driving modes – shaped like the thrust lever on a yacht, it forms a
highlight in the elegant interior of the sedan. The ergonomically
perfected lever communicates with the transmission electronically. Gear
changes are triggered by a brief tap of the lever, after which it
automatically returns to its center position. You can also change gears
using the rocker switches on the steering wheel.
The installation position of the new tiptronic follows a special
layout – as in many models from Audi: The differential lies in front of
the torque converter. The front axle is then moved forwards – the
advantages are a long wheelbase, a short front overhang and a finely
balanced weight distribution.
The quattro permanent all-wheel drive system equally contributes
to the new A8’s leading position. Its mechanical center differential
manages normal automotive operation: 60 percent to the differential of
the rear axle and 40 percent to the front – a sporty characteristic.
Should slip occur at a wheel, the differential sends the large part of
the torque to the axle with the better traction.
Customers with a particularly sporty driving style may decide on
the optional sport differential with its continuously variable
distribution of the drive forces between the rear wheels. With the
sport differential the A8 drives as if on the proverbial rails.
The sport differential’s controller is connected to the Audi drive
select vehicle dynamics system. The driver can switch between the
system’s three characteristics – auto, comfort and dynamic – at any
time.
Chassis
The new Audi A8 is the sportiest sedan in the luxury class. Its
chassis combines uncompromising precision with great dynamism, superior
stability and excellent comfort. Audi drive select is standard, with
optional dynamic steering. The large sedan impresses with its sprightly
agility. The A8 steers into the corners spontaneously and willingly,
driving through them almost neutrally and finding a strong grip on the
road at their exit thanks to quattro permanent all-wheel drive.
The subframe for the engine and the front axle forms the backbone
of the front suspension. The front axle is constructed from five
control arms per wheel; its aluminum forged parts provide low unsprung
mass and ultra-precise wheel guidance.
All A8 variants roll with the standard speed-dependent
servotronic. The steering gear is positioned low and well up front at
the subframe; the steering impulse is introduced directly into the
wheels through the track rods, with a very spontaneous response. With a
sporty and direct gear ratio of 16.1 : 1, the steering conveys a
precise and finely differentiated feedback from the road in any
situation. Its controlled vane-type pump operates with high efficiency.
The layout of the rear axle follows the track-controlled
trapezoidal link principle, which combines compact design with superior
driving and comfort qualities. Four steel tubes form the highly rigid
axle subframe. The two hollow-cast trapezoidal links, the wheel
carriers, the overhead transverse links and the track rods are made of
aluminum. Audi’s engineers have thoroughly overhauled the suspension.
The struts are supported directly by the wheel carrier, so that the
dampers respond with even greater sensitivity.
Audi drive select lends fascinating variety to the experience of
driving in the new A8 – from highly comfortable, gentle rolling to
sporty and exciting cornering. It integrates the adaptive air
suspension, the engine, the 8-speed tiptronic and the servotronic. With
the MMI the driver can change the characteristics of these systems
between the comfort, auto and dynamic modes. Moreover, the driver can
compose a fourth operating mode corresponding to his or her personal
ideal – the “individual” mode.
Always the right tuning: adaptive air suspension
The adaptive air suspension combines air suspension with
controlled damping. The struts are newly developed; an enlarged air
capacity now allows a soft characteristic even without an auxiliary
accumulator. The bellows and auxiliary air springs sensitively respond
even to a slight unevenness in the road surface. The shock absorbers
operate with high flexibility – their control unit constantly analyzes
the conditions and varies its mode of operation within thousandths of a
second.
The adaptive air suspension is a versatile technology. Depending
on the speed and the mode specified by Audi drive select, it lowers the
body by up to 25 mm, to increase stability and reduce drag and thereby
improve fuel consumption. One other operating mode is also available –
the “lift” mode slightly raises the body.
Audi drive select also has other components in store – the sport
differential and dynamic steering, which varies the steering ratio by
nearly 100 percent. At low vehicle speeds – during maneuvering, for
example – the steering system operates very directly; the power
assistance is also high. As the speed increases, directness and power
assistance continuously recede – on highways the A8 glides over the
asphalt with stoic calmness.
The dynamic steering cooperates closely with the ESP
stabilization system. If necessary, it slightly countersteers in the
handling limits when cornering – practically unnoticed by the driver,
it reduces understeer and oversteer in most situations.
The new A8 has a powerful brake system on board that is
consistently designed for maximum heat dissipation and low weight. All
four discs are internally ventilated; up front, stainless steel pins
connect the friction rings to the aluminum brake caps. This concept
from the sports car sector, new in the luxury class, saves up to 3.75
kg (8.27 lb) of weight per wheel. The ESP stabilization system can be
switched off and offers a sport mode.
The range of wheels underscores the strong character of the new
Audi A8. The sizes range from 17 to 21 inches. The tires have been
optimized with respect to comfort, aerodynamics and rolling resistance.
Safety
The new A8 is one of the safest cars on the market. It protects
its passengers with a high-stability body, adaptive restraint systems
and with the new Audi pre sense system. It’s available in a standard
version and in three expanded levels.
In the standard variant – Audi pre sense basic – the system
analyzes the information from the ESP sensors. When they signal maximum
brake application or skidding, the control unit intervenes. Depending
on the situation, it activates the hazard warning lights and closes the
side windows and the sunroof; it also tensions the front seat belts.
Electric motors trigger this process, which is reversible – if the
situation ends well, the belts are released again.
The expanded levels of the system are called Audi pre sense front,
Audi pre sense plus and Audi pre sense rear. They are integrated in the
optional assistance systems adaptive cruise control with stop & go
function and Audi side assist.
In interplay with ACC stop & go, Audi pre sense front
monitors the traffic in front of the new Audi A8 and supports the
driver in multiple stages. The first is a warning signal, and the
second a warning jerk in the form of a brief deceleration. If the
driver now depresses the pedal, the brake assist system initiates
precise braking relative to the preceding vehicle.
Even an avoidance maneuver – often the better solution – would
still be possible. Should the driver remain passive, the third stage
follows – autonomous partial braking that slows the A8 at a rate of 3
m/s2. Windows and the sunroof are closed, the hazard warning lights are
activated and the seat belts are tensioned.
If the full version of Audi pre sense plus is on board, a fourth
stage comes into play: braking with an initial deceleration of 5 m/s2
followed by maximum braking. This phase is initiated roughly one half
second before the collision. While a collision can no longer be avoided
in this case, its consequences are greatly ameliorated, for up to
impact the A8 has reduced the speed by about 40 km/h (24.85 mph).
The Audi pre sense rear system mitigates the consequences of a
rear end collision. Here, too, it closes the windows and sunroof and
tensions the seat belts. If the A8 has the optional front memory seats
on board, they move into a position that protects the passengers well.
The high-stability ASF body affords excellent protection in any
type of crash. In the interior the adaptive restraint system stands
guard. Particularly with smaller and lighter people it significantly
reduces the severity of injuries by intelligently managing the
interplay between the front airbags and the belt tension limiters. For
side collisions the A8 has side airbags in the backrests of the front
seats and the outside rear seats. The two head airbags extend from the
A-pillar to the C-pillar.
Assistance systems
The new A8 also demonstrates Audi’s concentrated innovative power
in its assistance systems, offering a wide, newly echeloned range of
high-tech systems. Compared with the competition, they are considerably
more efficient and intelligent, thanks to their pioneering new
networking.
The radar-aided automatic proximity control system, adaptive
cruise control with stop & go, has undergone intensive development.
Its two radar sensors are now located in the front end of the A8 in the
air inlets.
The system regulates the speed and the proximity to the preceding
vehicle in the range of 0 to 250 km/h (155.34 mph). In stop-and-go
traffic it decelerates the new A8 to a standstill. In short stops the
sedan automatically resumes moving when the preceding vehicle drives
off; after a longer stop the driver must tap the accelerator or the
cruise control lever.
Informed by the new navigation system, the ACC stop & go
function always knows where the A8 is located. It retrieves data from
up to 27 control units and operates closely together with the other
driver assistance systems, such as the rear radar of the Audi side
assist. Thanks to this high level of information the system can detect
complex scenarios and make anticipatory decisions in support of the
driver.
On the highway, if the car ahead puts on its right turn signal and
slows down because its driver wants to exit, the ACC stop & go
function recognizes this fact thanks to the camera image and because it
can read the exit from the route data supplied by the navigation
system. A conventional system would now brake analogously to the car
ahead; in many cases the A8 continues on almost without change.
Audi side assist: safety when changing lanes
At speeds of 30 km/h (18.64 mph) and above, Audi side assist
operates with two radar sensors in the rear that observe events
occurring behind the car. Should another vehicle be moving in the
critical area, the yellow LED indicator in the housing of the outside
mirror first lights up. If the driver nevertheless activates the turn
signal to change lanes, the indicator becomes brighter and begins to
blink quickly – a signal that can hardly be overlooked.
At speeds above roughly 65 km/h (40.39 mph), Audi lane assist
intervenes when the driver is about to leave the lane inadvertently. A
camera above the interior mirror observes the road. Software processes
the images, analyzing the lane markings and the course of the sedan.
Should it drive onto a line without signaling, Audi lane assist induces
a vibration in the steering wheel. The image data is also used by the
ACC stop & go function and the continuous headlight range control.
A totally new assistance system also profits from the camera – the
speed limit indicator, to follow in mid-2010. It detects speed limit
signs along the side of the road and presents them as graphics in the
instrument cluster display.
Also debuting in the Audi A8 is the night vision assistant. The
heart of this system is a thermal imaging camera sitting behind the
four rings at the front of the car. A computer transforms the
information from the camera into images and displays them on the
display located between the instruments.
The so-called remote infrared technology used by Audi looks ahead
by up to 300 meters (984 ft), depending on the driven speed. Because
the system reacts to the heat emitted by objects, people and animals
are generally displayed conspicuously bright, while the cool road
remains dark. The image processing software specifically seeks human
contours – yellow markings in the display highlight detected people. If
the person’s movements lead the control unit to assume a hazard, the
person is marked red and a warning gong sounds.
Infotainment systems
Audi has also set the bar significantly higher with regard to
multimedia technology with the new A8. The optional MMI navigation plus
system provides its data to other technology modules. Its new operating
concept with the touchpad – known as MMI touch – is another pioneering
idea. The phone, audio and infotainment features are equally state of
the art.
The core of the new technologies is the new MMI navigation plus,
integrating a large-sized hard disk for navigation, phone and audio
data. A graphics processor generates the high-quality,
three-dimensional images, which appear in the form of a 3D terrain
model. Besides the classic arrows, a new and animated display serves
the route guidance.
The database of the new MMI navigation plus describes the road
network with countless details. The system analyzes these data
predictively, reading the current course of the sedan but always
thinking a bit ahead. The data are relayed to the control units
managing the ACC Stop & Go, adaptive light and the 8-speed
tiptronic so that these systems can precisely adapt their function to
conditions well in advance.
MMI touch: a revolution in operation
Audi has entered a revolutionary new path in the operation of MMI
navigation plus: it uses a touchpad. To enter the destination or phone
number you simply draw the letters or numbers on the control panel with
the index finger of your right hand. The system even recognizes
Cyrillic, Chinese, Cantonese, Japanese and Korean characters. MMI touch
can also be used to navigate on the map. An intelligent auxiliary
feature is the Black Panel technology: Here the pad becomes a control
panel containing six programmed radio stations.
The new input technology functions intuitively and spontaneously.
The driver’s right hand is ideally guided by the selector lever of the
8-speed tiptronic. His or her finger draws the lines as if
automatically – and the driver's attention remains focused on the road.
The system acknowledges the input after each character with an acoustic
feedback signal. In contrast to voice control, touchpad input is
possible even while conversing or listening to an audio source.
Along with MMI touch, the new A8 also offers conventional
operation with the MMI rotary pushbutton. Further improved voice
control is also available on request: Places and roads can now be
spoken as commands.
A long line of hi-fi elements ensures perfect musical listening
pleasure. The Audi music interface is equipped with a USB and an Aux-in
connection to form a convenient interface for the customer’s iPod or an
external video source. Standard in the U.S. is the Bose surround sound
system, with a digital amplifier operating 14 speakers through 12
channels with an output of over 600 watts.
The pinnacle of hi-fi listening pleasure: the Advanced Sound System
At the top of the line is the Bang & Olufsen Advanced Sound
System. It is impressive for its sparkling brilliance, detailed
resolution and broad, finely differentiated frequency range. With their
digital output stages, two amplifiers with an output of over 1,400
watts operate 19 aluminum-encased speakers through 19 channels. The two
acoustic lenses in the cockpit are recessed and extend when the system
is started.
The new Audi A8 also offers rear seat entertainment. The
backrests of the driver and front passenger seats contain two flat
displays with 10.2-inch diagonals. Their inclination is adjustable, and
they can separately display different content. The sound passes through
headphones. The rear seat entertainment system has its own DVD drive, a
20 GB hard disk, two memory card slots and an AMI interface; it has
also has full access to all other infotainment systems on board. A
control panel in the rear center armrest serves the operation of the
system – another instance of first-class convenience.
Equipment and trim
The A8 is Audi’s new technological spearhead – and its equipment
underscores this standing. A broad range of high-end features are
already standard on this luxury sedan.
In the case of the engines, there is the recuperation system. As
for power transmissions, the new flagship shines with its
electronically controlled 8-speed tiptronic, quattro permanent
all-wheel drive and the sport differential.
In the running gear sector the A8 secures an exceptional standing
with Audi drive select; the system integrates the adaptive air
suspension together with active shock absorber control. The xenon plus
headlights, the Audi pre sense basic system and the anti-theft alarm
system serve security. The adaptive restraint system and a tire
pressure monitoring system reinforce the sense of safety on board.
When it comes to convenience, the new A8 impresses with its
electrical fold-in exterior mirrors, the versatile and electrically
adjustable front seats, the two-zone automatic air conditioning system,
the electrical adjustment of the steering
column with easy exit
function, the ambient lighting, the electro-mechanical parking brake
and the start-stop button.
The MMI operating system and the driver information system with
the multifunction steering wheel underscore the Audi brand’s leadership
role in ergonomics.
The new A8 also moves to the head of its class when it comes to
optional extras. In the case of the running gear the dynamic steering
deserves special mention. The wheels are up to 21 inches in size, with
a sporty tuning of the adaptive air suspension available from Audi on
request. The xenon plus headlights are perfectly supplemented by the
continuous headlight range control and the adaptive light system, and
the innovative full LED headlights give the luxury sedan an especially
impressive look.
In matters of safety, advanced levels of the new Audi pre sense
technology are optionally available: Audi pre sense front, Audi pre
sense rear and Audi pre sense plus, integrated in the adaptive cruise
control with stop & go function and in Audi side assist. The night
vision assist with its marking of detected pedestrians, Audi lane
assist, the parking assistance systems and the speed limit display,
which is to follow a bit later, also serve the driver’s safety and
convenience.
Practical everyday features include the luggage compartment
package and the load-through hatch with ski bag, supplemented by the
electric tailgate. For the doors there is electric power-assisted
closing, for the side windows noise- insulating glass.
High end: the A8’s optional extras
The line of luxurious optional extras is especially attractive.
Deserving special mention are the deluxe front center armrest, the
convenience key for accessing the vehicle, the electric sun blinds for
the rear, the 230 V outlet on the tunnel, the four-zone automatic air
conditioning, the auxiliary heating and the ambient light package. The
comfort seats for the driver and front passenger can be adjusted 22
ways; heating, ventilation and a massage feature with five programs are
available on request.
The new A8 also occupies a leading position in navigation and
infotainment systems. The top version, MMI navigation plus, reads the
course of the route in advance. The MMI touch also serves operation –
another solution from Audi that sets new standards. Three sound
systems, including the top-notch system from Bang & Olufsen, are
truly music to the ears, while a fully integrated rear seat
entertainment system is available for the rear. The new A8 also has
intelligent technologies on board for utilizing internet services.
For the distinct individualists among its customers Audi has
developed a wide range of interior colors, upholstery and inlays. The
Audi design selection impresses with especially exclusive combinations,
and with various optional packages containing leather, Alcantara and
decorative applications.
