POWER FOR THE SPEEDING BULLET
The exceptional blend of the Allroad vehicle concept-featuring four-level air
suspension, Quattro permanent all-wheel drive, and Tiptronic automatic
transmission with Dynamic Shift Program-is further enhanced by the addition of
the 4.2-liter V8 engine. The Allroad Quattro V8 now accelerates from 0 to
60 mph in just 6.9 seconds, with an electronically governed top speed of 130
mph.
The potent, 4.2-liter, 40-valve, all-aluminum alloy, DOHC V8 engine makes 300
horsepower
at 6,200 rpm, and 280 pounds feet of torque between 2,700-4,600 rpm. To incorporate
the 4.2 liter V8 into the Allroad Quattro's engine bay, the toothed belt
previously found at the engine's front end has been replaced by a chain drive
at the rear, and two controllable electric cooler fans that take the place of
the large viscous fan at the front of the vehicle. Compared with the
toothed-belt engine, the length of the already unusually compact Audi V8 engine
has thus been reduced further by 2.05 inches. The rear chain of the Allroad
Quattro 4.2-liter V8 drives the water pump, oil pump, hydraulic pump and AC
compressor. The transfer of the drive movements to these ancillary devices
take place via drive axle shafts. The four camshafts are driven
maintenance-free by chains.
Through the use of magnesium components,
engine weight have been reduced some 11lbs. compared to the other Audi V8
engines. A two-stage variable intake manifold made from magnesium
guarantees maximum engine output at higher speeds and ample low-end torque.
Continuous camshaft control also contributes toward impressive dynamism across
an extremely wide range of engine speeds. The Audi Allroad Quattro 4.2 V8
has one variable camshaft system per band of cylinders to vary the valve timing
of the inlet camshafts according to the engine speed range. An ample
torque curve across the entire speed band and quiet running in combination with
low exhaust emissions are the result.
The Motronic system integrates the
power take-offs of the Audi Allroad Quattro 4.2 into the engine management
concept in keeping with the level of torque. Its lambda control
permanently establishes the operating conditions and continually optimizes the
relationship between torque and fuel consumption, as well as the exhaust
emission values. Accelerator movements are translated directly into
propulsion by means of electrical pulses without any delay, (drive-by-wire).
Four knock sensors assure ultra-precise knock control. Cylinder-specific
ignition timing moreover assures exemplary engine smoothness and excellent idle
running.
The potent 4.2-liter V8 engine is mated to Audi's proven Quattro all-wheel
drive system and Tiptronic five-speed automatic transmission with an easy to operate auto/manual shift-gate.
By moving the leather topped shifter to the right
'auto/manual' notch, you can go up or down the five forward gears by just
pushing up or pulling back, for more heartbeat-quickening excitement on the
road.
Key to the versatility of the Allroad is its height-adjustable electronically
controlled pneumatic suspension. This innovation provides four-ground
clearance levels and automatic load leveling to adjust to a range of passenger
and cargo weights, including trailer tongue and towing weight. The
suspension can be raised or lowered on demand by simply pushing corresponding
buttons on a control panel at the top of the center console. The
suspension also automatically lowers at predetermined vehicle speeds, while a
delay circuit allows for frequently varying road speeds, such as temporary speed
reductions for construction zones.
The benefit of maximum ground clearance
is only realized if a vehicle can effectively navigate through varying terrain.
For this, the Allroad takes full advantage of its Quattro permanent
all-wheel-drive system. With both front and rear axles constantly engaged,
each tire exerts more force on the road-both in cornering and straight-line
driving. A Torsen self-locking center differential delivers up to
two-thirds of the engine's power to either axle, as needed, while Electronic
Differential Locks (EDL) engage at road speeds up to 58mph to maintain progress
even if only one tires has traction.
Adding to the Allroad Quattro's stability is the latest generation of the Audi
four-link front suspension with a built-in self-centering effect that is
especially critical on rugged terrain. In the rear, the double-wishbone
suspension is designed for directional stability and maximum ride comfort.
The brakes on the new V8 powered Allroad Quattro are big and powerful with 14-inch
vented rotors with a 4-piston caliper up front and 13-inch solid rotors clamped by
a single caliper in the rear. This powerful braking system is enhanced
with standard ABS and the Electronic Stabilization Program (ESP). By
constantly monitoring of wheel rotation speeds, steering angle, yaw rate and
lateral acceleration, ESP applies selective wheel braking to correct any
under-or-oversteer. ESP also intervenes if the vehicle begins to skid.
This new V8 powered Audi Quattro Allroad rides on unique 245/45R17
performance tires made with silicate formulas and a structure that easily adapts
to a full spectrum of surface conditions. These great all-season radial
tires wrap around rugged, 17 x 7.5-inch, 'twin-spoke' aluminum alloy wheels.
Guiding the new V8 powered Audi Allroad Quattro is Audi's proven Servotronic
speed sensitive rack & pinion steering system that is very responsive and
gives you excellent feedback from the road with a very good on-center feel.
The interior cabin is luxurious, comfortable, safe and very versatile in the
cargo area. All four doors open perpendicular to the body for real easy
entry and exit. A thick and wide beautiful dark wood strip runs around the
entire interior. Leather is found in each door's trim and the center
console comes with a padded leather top. All four door handles are made of
brushed aluminum. Only the finest materials are used inside for a real
luxury feel.
The 12-way power-adjustable and heated, front leather bucket seats were
developed exclusively for the Allroad and are very comfortable and supportive,
especially during rigorous off-road and demanding on-road maneuvers. The
power tilting/telescoping, leather wrapped steering wheel feels perfect in your
hands, and contain controls for the great audio system. The center stack
is within easy reach to use the dual-zone, electronic climate control system,
heated seat controls, four-level suspension settings, ESP traction control on/off
button, and the magnificent Audi Symphony audio system with powerful AM-FM
stereo radio, cassette deck and 6-CD player. This great system comes with
eight speakers.
The instrument panel is very easy to see and understand with a
big 160 mph speedometer, 8,000 rpm tachometer and smaller gauges for fuel, engine
coolant temperature, oil pressure and voltmeter. Bright LED readouts warn
of system or safety failure. In the middle of the instrument panel is a
screen displaying information such as current radio station, outside
temperature, instant mpg, etc. It also displays information to use when
you use the optional navigation system. No map, but directing you on the
screen when to turn right or left at designated streets, avenues or boulevards.
There is an audio help where the system tells you when to turn left or right.
At night the amber red lamps give a warm glow when traveling.
The center
console is also elegant with a full dark wood cover and brushed aluminum shift
gate. The leather topped shifter feels very comfortable in your hand.
A single cupholder pops out from the top of the center stack and it is next to a
pop-out draw to hold coins or other small and flat items. The
pull-down center console opens to reveal two cupholders for the rear passengers
to use. The unique cargo area has 60/40 split rear seating for
versatility, a manual sunshade for the rear hatch glass, a pull-up partition net
that attaches to the headliner stopping cargo from entering the passenger
compartment during spirited driving or during severe maneuvers, a full-length
cargo-net and many chrome tie-downs to arrange your cargo keeping it as secure
as possible. Maximum cargo capacity with the second-row seats down is 73
cubic feet.
Other standard features include heated rear seats, front and rear underbody
protection, front and rear power windows with one-touch down/up and pinch
protection, automatic door locks, remote keyless entry, pollen filter, remote
rear hatch opener, full-perimeter thick-pile carpeting, grab handles above each
door, electronic cruise control, locking glove box,18.5 gallon fuel tank, and a
powerful concealed headlight washer system. An electric sunroof is
optional.
Standard safety features include driver and front passenger 'next generation'
airbag supplemental restraint system, driver and front passenger seat-mounted
side airbag, SIDEGUARD inflatable curtain airbags, lower anchors and tethers for
children (LATCH), front and rear 3-point safety belts with automatic
pretensioning, front belts with load limiters, side impact protection, body
crumple zones, side-marker lights, and an anti-theft alarm system.
The new, more powerful Audi Allroad Quattro is a great alternative to the big
and bulky sport utility vehicles massing on the roads today. It gives you
the same multi-function versatility, but with better handling and
maneuverability. With a luxurious, quiet and safe cabin, plus the proven
Quattro all-wheel-drive system and four-level suspension height settings,
there's no stopping this silver bullet, no matter the task.
