The Audi A4 allroad quattro: A car that knows no
A car that knows no boundaries: Audi is launching the A4 allroad quattro.
With its quattro permanent all-wheel drive and increased ground clearance,
this vehicle can handle any road or trail. Starting in early summer, the Audi
A4 allroad quattro will be available with one of three powerful and energy-
efficient engines, the high-tech S tronic transmission, and a broad range of
assistance and communication systems. Its basic price will be 37,100 euros.
A relative of the A4 Avant, the A4 allroad quattro is a clever companion during
everyday driving as well as for sports and leisure. The luggage compartment
has a capacity of 490 liters (17.3 cubic feet), which extends up to 1,430 liters
(50.5 cubic feet) when the split folding rear seat backs are fully folded down.
A light touch triggers the standard load-area cover to retract upward. And the
reversible loadliner’s underside has been designed as a dirt-resistant tray. Audi
offers optional extras such as a load-securing set and an electromechanical
assembly for the tailgate.
The Audi A4 allroad quattro is somewhat larger than the A4 Avant. It measures
4.72 meters in length (15.49 ft) and 1.84 meters in width (6.04 ft). At a height of
1.50 meters (4.92 ft), it is taller than its A4 Avant sibling: ground clearance has
risen to 180 millimeters (7.09 inches). A series of design flourishes underscores
the vehicle’s expressive nature and superiority on any road or trail. The fenders
have become more flared; the wheel arches and the side sills bear vigorous insert
strips; and underneath the front end and tail end, the vehicle has a solid stainless-
steel underbody guard. 17-inch lightweight alloy wheels in 7-arm design are
standard, and the roof is capped off by an offset rail.
Audi will initially offer three different powerful and highly efficient engines for
the A4 allroad quattro: a gasoline engine and two diesel units. All three combine
the technologies of direct fuel injection and turbocharging. The 2.0 TFSI delivers
155 kW (211 hp) and 350 Nm (258.15 lb-ft) of torque. The 3.0 TDI produces
176 kW (240 hp), which enables a sprint to 100 km/h (62.14 mph) in 6.4 seconds.
The 2.0 TDI with manual shifting provides 125 kW (170 hp), yet requires just
6.4 liters of fuel per 100 km (36.75 U.S. mpg). This is partially due to the
synergetic impact of new efficiency technologies by Audi: an energy-recovery
system, a start-stop system, and an on-board computer with efficiency program –
all standard as of summer 2009.
Whereas the 2.0 TDI links to a six-speed manual transmission, the 2.0 TFSI
and the 3.0 TDI can transmit power to Audi’s optional, innovative dual-clutch
transmission. The S tronic operates very efficiently, switching extremely
smoothly among its seven gears at lightning speed. The driver can shift manually
or allow this transmission to shift automatically.
Standard: The quattro permanent all-wheel drive system
The quattro permanent all-wheel drive system is also standard equipment in
Audi’s latest model. It slightly favors the rear, distributing power for sporty
handling similar to that of the A4 Avant. The finely balanced distribution of
the axle loads and the high-tech chassis play key roles in this regard.
In rough terrain, the Audi A4 allroad quattro relies on a cutting-edge feature:
Offroad Detection technology identifies the type of driving surface and
accordingly adjusts the control parameters of the electronic stabilization program
(ESP). The optional vehicle-dynamics control system known as Audi drive select
enables dynamic road handling. The system is paired with Audi dynamic steering,
which varies the steering ratio in a continuously variable manner – more directly
at low speeds and more indirectly at high speeds.
A wide range of optional assistance systems straight from the luxury class will
appeal to customers who set great store by convenience. Audi lane assist helps the
driver to remain in a given lane and Audi side assist makes it safer to change
lanes. Adaptive cruise control is a radar-assisted cruise-control system which
detects vehicles ahead and maintains the proper following distance by accelerating
and braking automatically. In dangerous situations, this system alerts the driver
via one of two alarms.
There are also appealing multimedia options for this vehicle, from the innovative,
high-tech MMI navigation plus system to the Bang & Olufsen sound system. The
Audi A4 allroad quattro will be available at dealerships early this summer at a
basic price of 37,100 euros.

A car that knows no boundaries
The Audi A4 allroad quattro
The Audi A4 allroad quattro is right at home on any road or trail. With its
permanent all-wheel drive and increased ground clearance, it offers driving
pleasure even on unpaved surfaces. The Audi A4 allroad quattro also
features all the technologies which impart superiority to the A4 model line:
powerful and highly efficient engines, the vehicle-dynamics control system
known as Audi drive select, the high-tech S tronic transmission, and
innovative communication and assistance systems. Sales will begin in early
summer, starting at 37,100 euros.
The Audi A4 allroad quattro’s design recalls the A4 Avant, the most attractive
standard-size station wagon. Its outer skin appears taut and eager. Crisp lines
enclose tastefully curved surfaces; the starkly sloped coupé-like roof line, with its
boldly slanted D-posts, brings out the dynamic contours. A nearly invisible zero-
gap joint unites the side panels with the roof. This joint created via plasma brazing
illustrates the great precision with which Audi designs and manufactures its
Striking details re-interpret this model line’s sporty vigor. Underneath the engine
compartment, the A4 allroad quattro has a solid stainless-steel underbody guard.
This protrudes slightly upward at the front end and serves as an air inlet. The
single-frame grille has a Luna Gray paint finish, and its vertical bars are in
chrome. A new, striking bumper with pronounced air inlets underscores the
vehicle’s unique identity; chrome rings encircle the standard halogen front fog
The headlights provide an aesthetically pleasing stage for sophisticated Audi
technology. The headlights’ wings (chromed plastic contours) have become one
of the brand’s calling cards, and are shaped differently depending on the headlight
version. Whereas incandescent bulbs comprise the halogen daytime running
lights, the xenon plus version features sweeping slivers of light, each consisting of
14 white light-emitting diodes. These consume just nine watts of power, and thus
play an admirable role in reducing CO2 emissions.
The A4 allroad quattro’s front fenders and rear side panels have a new and
muscular look. Circumferential plastic trim protects the wheel arches and the side
sills against contact; it is matt Platinum Gray or Black, depending on the vehicle’s
paint finish. The roof is capped off by an offset rail with two high crosspieces.
Viewed from the side, the 17-inch wheels in 7-arm V design exude enormity and
strength with their overall diameter of 690 millimeters (27.17 inches). Audi also
offers 18-inch wheels fitted with 245/45 tires.
Expressive: The rear view
The rear of the Audi A4 allroad quattro is also full of character. In the version
featuring xenon plus headlights, light-emitting diodes lend sparkle to the taillights
and comprise a continuous sliver of light. The lights taper inward, emphasizing
the horizontal lines and consequently the vehicle’s width. Narrow reflectors in the
redesigned bumper and the tailgate’s prominently three-dimensional contouring
enhance this effect.
The stainless-steel rear underbody guard’s ribbed structure visually mirrors the
theme of the front air inlet, and also integrates the exhaust system’s tailpipes.
On the 2.0 TDI, the tailpipes appear side by side on the left; on the 2.0 TFSI
and 3.0 TDI, they terminate to the left and to the right.
Two exterior packages impart an individual look to the A4 allroad quattro. The
aluminum look features window frames and roof rails made of aluminum as well
as supplementary moldings in the sill extensions made of stainless steel. A full
paint finish builds on this version: the circumferential inlay is painted the same
color as the body.
A full paint finish is available in eight colors: Ibis White, Ice Silver, Condor Gray,
Meteor Gray, Phantom Black, Deep Sea Blue, Teak Brown, and Dakar Beige.
Audi also offers four additional options: Stratos Blue (exclusively for the
A4 allroad quattro), Sphere Blue, Garnet Red, Lava Gray, and Brilliant Black.
The Audi A4 allroad quattro’s measurements are as follows: 4.72 meters in length
(15.49 ft), a wheelbase of 2.81 meters (9.22 ft), 1.84 meters in width (6.04 ft), and
1.50 meters (4.92 ft) in height. When the vehicle is unloaded, its ground clearance
is 180 millimeters (7.09 inches), which is 37 millimeters (1.46 inches) more than
the Audi A4 Avant. The basic version’s frontal area is 2.24 m2 (24.11 ft2) and the
drag coefficient is just 0.34 thanks to extensive fine-tuning and a fully clad
The body integrates a number of high-strength and ultra-high-strength steel panels
which – in turn – reduce the car’s weight while enhancing its rigidity, vibrational
comfort, and impact safety. At the body’s heart, however, are the hot-formed steel
units – at the center tunnel, B-posts, inner sills, and bulkhead transverse member.
These steel units provide exceptional tensile strength, yet comprise just 11 percent
of the bodyshell’s weight.
High-tech solutions: Assembly
In addition to resistance spot welding, Audi uses a high-quality structural adhesive
while assembling the vehicle’s body to further bolster the strength of joints. In the
doors and near the sills, an additional high-precision technology is used to reduce
the vehicle’s weight: remote laser welding.
An array of precisely arranged metal sections protects Audi A4 allroad quattro
passengers in the event of an accident. Both front airbags acknowledge the precise
positions of the driver and front-seat passenger; in conjunction with the adaptive
seatbelt tensioners, passengers of all sizes enjoy excellent protection. In addition,
there are side airbags in the front and, optionally, in the rear, as well. Last but not
least, a head-protection airbag system also stands at the ready.
In the event of a rear-end collision, a standard, integral head-restraint system for
front-seat passengers diminishes the risk of whiplash by supporting the upper
parts of their bodies. And the seatbelt tensioners ensure that passengers remain
safely seated during a severe rear-end collision. An optional ISOFIX child-seat
anchor can be integrated in the front passenger seat; an on/off switch for the
airbag is also available.
The Audi A4 allroad quattro’s luggage compartment features a load-through hatch
one meter in width (3.28 feet) and can hold cargo 1.03 meters (3.38 feet) in length;
its base capacity is 490 liters (17.3 cubic feet). It is lined with high-quality carpet.
And thanks to the ingenious design and low loading sill covered by a stainless-
steel protective molding, the luggage compartment is extremely handy. The rear
seatbacks, split 40:60, can be folded down with two flicks of the wrist to increase
the luggage compartment’s capacity to a length of 1.78 meters (5.84 feet) and a
volume of 1,430 liters (50.5 cubic feet).
Befitting its versatile nature, the A4 allroad quattro boasts a wealth of intelligent
touches. The load guard and the deluxe load-area cover are stored in separate
compartments for the sake of simplicity. A mere tap of the hand actuates a spring,
causing the cover to automatically retract upward between two guideways. Pulling
the cover down also could not be easier. When the tailgate is fully open, people
1.89 meters (6.2 feet) in height can stand underneath it!
Intelligent touch: The reversible loadliner
Like the roof rails, the reversible loadliner is convenient standard equipment.
Located in the rear of the luggage compartment, its underside has been designed
as a water-resistant and dirt-resistant tray, making it the ideal place to store wet
ski equipment and the like. Two handles allow you to grip and carry the loadliner
like a tray. Additional standard equipment includes four sturdy fastening rings,
two elegant bag hooks, a 12-volt outlet, and a shelf to the side with a horizontally
A series of optional features makes the Audi A4 allroad quattro even more
practical. There is a reversible mat with a fold-out cover for the bumper, an
electromechanical assembly for the tailgate, and a load-securing set, which
includes a telescopic rod and a spring-loaded tensioning strap. Latched to rails in
the floor, the load-securing set allows the customer to divide the luggage
compartment as they wish. The rear seats optionally feature a load-through hatch
with a ski bag. Additional optional equipment includes a trailer hitch and special
roof rack for bicycles, skis, and kayaks.
Plenty of room, uncompromising quality, and flawless functionality: the interior
of the Audi A4 allroad quattro embodies all the strengths Audi is famous for. It is
tailored like a sleek-fitting suit: bright, elegant, clear. The shapes, the materials
chosen and used, the haptic charm of the surfaces: the interior offers sensory bliss.
The front seats are contoured and low-slung, perfectly integrating the driver and
passengers into the sporty ambience. Beyond the standard height-adjustable seats,
Audi also offers electrical adjustability and a seat-heating system – optionally for
the outside rear seats, as well.
The optional sports seats have pronounced side sections, pull-out thigh supports,
and four-way lumbar support. And the climate-controlled comfort seats offer the
utmost in luxury: not only can they be heated, they also deliver relief on hot days
thanks to an integrated cooling unit with small fans. And if the temperature could
become chilly, then an auxiliary heater automatically turns on.
The A4 allroad quattro’s long wheelbase ensures plenty of interior space in the
rear as well as in the front. Large cup holders and spacious storage compartments
hold bottles and other items. An optional storage package features additional
compartments and nets. A center armrest with storage box and two 12-volt outlets
are available for the front seats. The armrest can be moved toward the front or
rear, is height-adjustable, and features especially soft upholstery.
Focus on the driver: The cockpit
The cockpit is clearly aligned toward the driver. The center console is offset to the
left by eight degrees; the steering wheel is adjustable for height and reach. The
dashboard’s large and easy-to-read instruments constitute classic Audi styling
elements. The center display is standard; its screen is between the speedometer
and the tachometer.
The standard CD sound system “chorus” delivers 80 watts to eight speakers; its
switches and pushbuttons are easily accessible in the center console. Underneath
the sound system is the control panel for the standard automatic air conditioning
system: a cutting-edge unit which is extremely efficient, strong, quiet, and
luxurious. Audi also offers a deluxe automatic air conditioning system which
maintains the interior temperature in three separate zones.
Another particularly luxurious feature is the high-beam assistant. Aided by a small
light-sensitive detector, it automatically switches between high beams and low
beams. In the version featuring xenon plus headlights, their range is dynamically
adjusted. When the A4 allroad quattro reaches 120 km/h (74.56 mph), the
headlights are adjusted slightly upward for highway driving.
A large on-board monitor with a 6.5-inch screen is high up and in the center of the
cockpit. The screen is in color in conjunction with the concert and symphony
sound systems, or with the MMI Navigation system plus. The Multi Media
Interface’s control unit is housed in the center console. The large buttons around
the central rotary pushbutton encourage intuitive operation. The center console
also houses the button for the standard electromechanical parking brake; the
optional Audi hold assist enhances the brake’s functionality.
Sporty elegance: Color and trim
Sporty elegance also characterizes the interior’s colors and materials. Carpeting is
made of velour; the headlining is star silver, linen beige, or black (optional). The
air vents, the parking brake’s button, and the light switch gleam thanks to their
aluminum look. And the door sill trims bear special allroad logos. Standard inlays
are micrometallic platinum; options include aluminum trigon, open-pored and
dark fine-grain ash, laurel nutmeg, and walnut brown.
Customers can choose one of several different trim materials: an exclusive allroad
fabric, two types of leather (Milano or Valcona), or an Alcantara/leather
combination. The fabric designs are available in black or pale gray, and the leather
trim in seven colors – two of which feature sporty contrasting stitching. The Audi
exclusive program offers additional exquisite leather options for individualists.
Audi will initially offer three different engines for the A4 allroad quattro: a
gasoline unit and two diesel engines. All three are turbocharged with direct fuel-
injection as per the TFSI or TDI principle. They are impressive for their excellent
performance, impressive pulling power, smooth running, and high fuel efficiency.
The 2.0 TFSI – voted “Engine of the Year” on four consecutive occasions by an
international panel of experts – incorporates three high-end technologies in this
latest stage of its evolution: FSI direct gasoline injection, turbocharging, and the
Audi valvelift system, which boosts pulling power by variably controlling the
exhaust valves’ lift. Direct fuel injection and turbocharging have been a successful
combination at Audi for years, as the R8 racing car has demonstrated with its
triumphs at the Le Mans 24 Hours and many other events.
High compression ratio: Ensuring excellent efficiency
In the high-volume engine as well, this technological twosome is a perfect
solution. Injected at a pressure of 150 bar in the 2.0 TFSI and then swirled by
flaps, the gasoline vaporizes and thus removes heat from the combustion
chambers – this in turn solves the conventional turbocharging problem of engine
knock. This facilitates a compression ratio of 9.6:1 for excellent efficiency.
The 2.0 TFSI, which delivers power from a displacement of 1,984 cm3, provides
additional high-tech features. All components have been designed to minimize
friction and the oil pump works very efficiently. The crankcase weighs just over
30 kilograms (66 pounds). Two balance shafts contribute to excellent refinement,
and the intake camshaft can be adjusted by 60 degrees.
The turbocharger and its intercooler have been optimized for sporty
responsiveness and a high efficiency ratio. Between 1,500 and 4,200 rpm, the
four-cylinder engine delivers 350 Nm (258.15 lb-ft) of torque to the crankshaft.
Peak output is 155 kW (211 hp). In conjunction with the S tronic dual-clutch
transmission, the 2.0 TFSI propels the Audi A4 allroad quattro to 100 km/h
(62.14 mph) in just 6.9 seconds, and to a top speed of 230 km/h (142.92 mph).
On average, it consumes a mere 8.1 liters of fuel per 100 km (29.04 U.S. mpg).
TDI, the world’s most successful efficiency technology, also stands for modern
and smart sportiness: terrific torque, powerful performance, excellent refinement,
and outstanding fuel efficiency. It was back in 1989 that Audi introduced TDI.
And the brand with the four rings has been continuously consolidating its
technological superiority ever since. The R10 TDI racing car proved with its
victories at Le Mans just how muscular diesel can be.
Top of the engine range is the 3.0 TDI, featuring six cylinders in a 90-degree
V configuration. The cylinder block is made of vermicular-graphite cast iron, a
high-tech material which unites high rigidity with low weight. Intensive finishing
grinding reduces internal friction. The cylinder barrels, for example, are
illuminated by a laser beam, which reduces the tension forces at piston rings and
further increases service life.
A common-rail system providing injection pressure of 1,800 bar and lightning-
fast piezo injectors precisely prepare the mixture. A speedy electric motor adjusts
the turbocharger’s vanes and the intercooler attains especially high thermal
efficiency. The V6 diesel also excels via clean exhaust with a low proportion of
Robust crankshaft: 500 Nm of torque starting at 1,500 rpm
The 3.0 TDI, which delivers 176 kW (240 hp) from a displacement of 2,967 cm3,
transmits – at 1,500 to 3,000 rpm – 500 Nm (368.78 lb-ft) of torque to the
crankshaft, which remains unperturbed by such a blast of power. The Audi A4
allroad quattro 3.0 TDI, aided by the high-tech S tronic transmission, reaches
100 km/h (62.14 mph) in just 6.4 seconds, and tops out at 236 km/h (146.64 mph).
On average, the three-liter engine sips only 7.1 liters of fuel per 100 kilometers
(33.13 U.S. mpg). Like all engines in this portfolio, it already meets the Euro 5
emission standard; as in the case of the 2.0 TDI, a particulate filter is standard.
As for the 2.0 TDI, the successor to the world’s most-built diesel engine ever,
a common-rail system with four piezo injectors provides injection pressure of
1,800 bar and ensures excellent refinement. Up to five precisely modulated
injection processes take place during every power stroke. Two balance shafts
counteract the second-order inertial forces. Adjustable vanes in the turbocharger,
swirl flaps in the intake manifold, and specialized dimensional characteristics of
the pistons collectively optimize charging efficiency in the combustion chambers.
The four-cylinder engine can operate on a high proportion of cooled exhaust gas,
which removes a significant amount of nitrogen oxides from untreated emissions.
From a displacement of 1,968 cm3, the two-liter diesel engine delivers 350 Nm
(258.15 lb-ft) of torque to the crankshaft between 1,750 and 2,500 rpm. A
respectable 125 kW (170 hp) provides good output: the Audi A4 allroad quattro
2.0 TDI reaches 100 km/h (62.14 mph) in 8.9 seconds and a top speed of
213 km/h (132.35 mph). It nevertheless requires just 6.4 liters of fuel per 100 km
(36.75 U.S. mpg) on average.
New efficiency technology: The start-stop system
This high fuel efficiency is largely due to the synergetic impact of new
technologies from Audi’s modular efficiency platform. The 2.0 TDI and the
2.0 TFSI will incorporate three such technologies as standard equipment starting
in summer 2009. First among them is a high-performance start-stop system. It
reduces fuel consumption by some 0.2 liters/100 km, which equates to 5 grams of
CO2/km (8.05 g/mile).
The start-stop system achieves especially impressive fuel savings regarding city
driving. As soon as the vehicle comes to a stop, the shift lever is in neutral, and
the driver removes their foot from the clutch pedal, the system turns the engine
off. It then turns the engine back on as soon as the clutch pedal is depressed.
The start-stop system functions quietly, conveniently, and quickly. When the
driver puts the vehicle in gear, the engine instantaneously returns to its idle speed.
A mighty battery ensures flawless operation even at low temperatures; it is
deactivated only during the engine’s warm-up period. The driver can turn the
system on or off at the touch of a button at any time.
The second of the three efficiency technologies is the energy-recovery system.
During a vehicle’s braking and coasting phases, it converts kinetic energy to
electrical energy, which is temporarily stored in the electrical system’s battery.
When the vehicle resumes acceleration, the battery supplies this stored energy to
the engine – thus reducing the load on the alternator.
The third new module from the modular efficiency platform is the new on-board
computer with efficiency program. Via the instrument panel’s display screen, it
portrays all data regarding fuel efficiency. The efficiency program continuously
monitors energy consumption by various components in the car and, if desired,
displays the key sources of consumption. In some cases, it provides advice to the
driver – to close the windows if the air conditioning is turned on, for example.
This new system makes driving even more fun, yet also reminds drivers of their
own responsibility. After all, some 30 percent of fuel consumption depends on the
Each of the transmissions for the A4 allroad quattro has been integrated into the
innovative basic layout of the A4 family. The differential is in front of the clutch
and immediately behind the engine. This technical stroke of genius made it
possible to reposition the front axle much closer to the vehicle’s front end, in turn
allowing for a longer wheelbase and an ideal distribution of the axle loads. This
modification was simplified by relocating the battery to the luggage compartment.
The benefits include excellent dynamism, steady straight-line stability, and superb
All the engines transmit their power to a six-speed manual transmission. Short
gearshift travel makes ultraprecise shifting child’s play and the intelligent
placement of the shift forks protects the shift lever against vibrations. The
manual transmission also excels thanks to its low weight and a high efficiency
ratio; a broad array of measures reduces internal friction. A redesigned gearshift
indicator – the on-board computer with efficiency program integrated in the driver
information system – unmistakably notifies the driver via different sizes and
colors as soon as it becomes sensible to shift gears to conserve fuel.
High-tech excellence from Audi: Seven-speed S tronic
Audi includes a high-tech transmission as optional equipment for the 3.0 TDI and
2.0 TFSI. The highly efficient, seven-speed S tronic distinguishes itself by precise
control management, a high efficiency ratio, and a broad spread of the gear ratios.
First gear is sporty, seventh fuel-sipping.
The seven-speed S tronic consists of two sub-transmissions, which are alternately
actuated by two clutches. This dual-clutch transmission can thus shift extremely
smoothly within a few hundredths of a second – cutting-edge technology in
motion! The electronic control management has a fully automatic mode at the
ready, with two types of operation: D (Drive) and S (Sport). The driver can use
the selector lever to shift whenever they wish, even via optional shift paddles on
the steering wheel.
Regardless of the engine type underneath an A4 allroad quattro’s hood, quattro
permanent all-wheel drive is standard. It ensures those superior properties which
long ago became bywords for the Audi brand: outstanding driving dynamics,
traction, driving safety, and straight-line stability all symbolize Audi’s renowned
Vorsprung durch Technik. Regardless of conditions, the Audi A4 allroad quattro
offers excellent stability and is an ideal towcar.
The classic heart of the quattro drivetrain is a self-locking center differential,
which operates by purely mechanical means and therefore instantaneously. Under
typical driving conditions, it distributes 40 percent of the torque input to the front
axle and 60 percent to the rear axle for sportiness. In the event of axle slippage,
the differential transfers a majority of the power to the other axle. Should a wheel
somehow nevertheless slip, then the electronic differential lock (EDL) brakes that
wheel to improve traction. EDL also promotes smooth starts.
The Audi A4 allroad quattro is a close relative of the A4 Avant, and its chassis
retains all the advantages which distinguish the A4 model line. The chassis
spontaneously adapts when the vehicle enters a curve; it is also superbly stable
and nearly neutral at the A4 allroad quattro’s impressive cornering limit. The
vehicle’s width lays the foundation for these remarkable attributes. The car’s track
is 1,583 mm (62.32 in.) at the front and 1,574 mm (61.97 in.) at the rear – some
20 mm (0.79 in.) wider, respectively, than the A4 Avant.
At a ratio of 16.1 : 1, steering is straightforward. The low-mounted steering gear
conveys the driver’s input directly to the wheels. Feedback from the road is
responsive: traction forces and disruptive forces are practically imperceptible.
Exact centering when driving in a straight line facilitates precise steering from the
central position. The steering box’s power-steering pump conveys just the
required amount of oil, conserving some 0.1 liters of fuel per 100 kilometers.
The 3.0 TDI and the 2.0 TFSI roll off the assembly line with servotronic, which
adjusts its power-steering assistance to the current speed of travel.
Key components of the front suspension are made of lightweight aluminum:
a support for the engine and axle, firmly bolted to the front end to boost rigidity;
a mounting bracket connecting the upper trailing arm with the body; a pivot
bearing; and five trailing arms per wheel. A tubular anti-roll bar also cuts down
on weight. A five-link suspension can handle longitudinal and lateral forces
separately. Their bearings are rigid when crosswise, fostering sporty precision;
on the other hand, the bearings are remarkably pliable when lengthwise.
The design of the rear axle on the A4 allroad quattro is based on Audi’s principle
of the self-tracking trapezoidal link, which unites compact construction with
top-notch comfort and drivability. A steel subframe connected to the body via
hydraulic bearings constitutes the ultrastrong backbone. The trapezoidal link, the
wheel carriers, the overhead control arms, and the tie rods are made of aluminum;
the anti-roll bar is a hollow tube. The springs are supported directly by the wheel
carriers, and are housed separately from the shock absorbers to facilitate ideal
The body is higher than that of the Audi A4 Avant by 37 millimeters (1.46 inches)
thanks to correspondingly modified shock absorbers. The Audi A4 allroad quattro
standard, 17-inch lightweight alloy wheels in 7-arm V design are fitted with
225/55 tires. 17-inch winter wheels are also optionally available. Audi also offers
18-inch wheels in 5-arm and 10-spoke designs, fitted with 245/45 tires.
A tire-pressure monitoring display for all wheels is standard.
Strong stopper: The wheel brakes
Like every Audi, the A4 allroad quattro boasts powerful brakes. The brake disks
have a diameter of 314 millimeters (12.36 inches) at the front (320 millimeters
(12.60 inches) for the 3.0 TDI) and 300 millimeters (11.81 inches) at the rear.
The high-performance brake pads generate a high coefficient of friction and are
practically impervious to brake fade. The ventilated front disks have been
designed to maximize heat dissipation. In lieu of conventional cooling ducts,
hundreds of tiny metal cubes connect the two disk halves – thus allowing a large
volume of air to escape. The wheel brakes are very low in weight. The 3.0 TDI
has floating calipers at the front; their composite construction consists of high-
strength nodular cast iron and aluminum.
The electronic stabilization program (ESP) provides precise and unobtrusive
assistance. In rough terrain, a cutting-edge standard feature is put into play:
Offroad Detection technology automatically identifies the type of driving surface
and accordingly adjusts the ESP’s control parameters. When the driver depresses
the gas pedal, ESP increases propulsive power by tolerating more wheel spin than
otherwise. If necessary, it will brake for a long time in the interest of safety.
On paved roads, the optional Audi drive select system further enhances the joys of
driving. It is always paired with Audi dynamic steering in the A4 allroad quattro.
Consisting of a superposition gear system integrated in the steering column, Audi
drive select varies the steering ratio in a continuously variable manner by nearly
100 percent. It functions directly at low speeds and indirectly at high speeds; the
power steering adjusts correspondingly.
If the A4 allroad quattro is at the limits of handling – oversteering, understeering,
or during braking maneuvers where one side of the car could skid – Audi dynamic
steering keeps the car on course via minor split-second corrective actions. It thus
eliminates the necessity for extensive ESP intervention, making driving even safer
The Audi A4 allroad quattro will be available at dealerships early this summer at a
basic price of 37,100 euros. It is generously equipped with 17-inch lightweight
alloy wheels, front fog lights, a headlight washer system, roof rails, a deluxe load-
area cover, a reversible loadliner, an automatic air conditioning system, an
electromechanical parking brake, and a sound system with CD player.
Optional equipment also includes a multitude of attractive features. The two-part
panoramic glass roof with an electrically operated interior shade suffuses the
interior with sunlight and fresh air. The optional steering wheels bear three or
four spokes and multifunction pushbuttons. For the 2.0 TFSI and the 3.0 TDI,
shift paddles are available. The lights package provides small spotlights for the
interior. Complementary to the light and rain sensors, the high-beam assistant
automatically switches between high beams and low beams.
You never need to remove the advanced key from your pocket: it communicates
remotely with the car and you simply push a button on the center tunnel to start
the engine. Additional luxurious options include the electromechanical tailgate,
the deluxe automatic air conditioning plus, the xenon plus headlights with LED
daytime running lights and LED taillights, the cornering light system known as
adaptive light, climate-controlled comfort seats, sun shades for the rear side
windows, Audi drive select, both exterior packages, and the alarm system.
If a customer so desires, they can take delivery of an A4 allroad quattro with
innovative assistance systems straight from the luxury class. Audi lane assist helps
the driver to remain in a given lane via a small camera; Audi side assist employs
radar to help drivers change lanes more safely.
Adaptive cruise control is a radar-assisted cruise control system which detects
vehicles ahead and maintains the proper following distance by briefly decelerating
or accelerating on its own. Should the rate of deceleration not suffice, the system
alerts the driver via one of two alarms based on the extent of danger. The Audi
parking system advanced features a rear-view camera; its images are displayed
via the on-board monitor.
Multimedia by Audi: The very best in infotainment
Audi also offers an intelligent array of multimedia modules, and a navigation
system is available. The MMI navigation plus system belongs to Audi’s cutting-
edge generation of new high-tech devices. It integrates a color screen with three-
dimensional maps, a DVD player, a voice-activated unit facilitating whole-word
commands, and a large hard disk drive which stores data for navigation, music,
and phoning. A joystick-like cap on the MMI terminal makes it simple to use the
navigation plus system.
Various cell-phone solutions enable convenient phoning. The premium option is
the Bluetooth car phone with cordless handset, which uploads data from the
driver’s personal cell phone via the SIM Access Profile. Signals are processed
digitally and the vehicle’s sound system transmits the voices. A voice control
system is required for the Bluetooth car phone as well as the audio and navigation
Component concept: The sound systems
Audi also offers sophisticated audio-system packages, either as part of a
navigation system or individually. The concert sound system has a color screen
and a memory card reader; the symphony sound system adds to that a six-disk CD
changer. The Audi music interface seamlessly incorporates the customer’s iPod
into the system; the Audi sound system integrates a 180-watt six-channel
amplifier and ten speakers.
But the sound system by Danish hi-fi specialists Bang & Olufsen is the top-of-the-
range solution. Its ten-channel amplifier delivers 505 watts of breathtaking
surround sound via 14 high-performance speakers concealed behind aluminum-
inlay covers. Both sound systems can be rendered even more sophisticated by
means of tuner modules for digital TV/radio reception. Audi also offers a rear-seat
