(from Audi Press
Release) Aggressive power and Audi ultra – the Audi R8 GT
limited-production, top-of-the-line version of the
high-performance sports car
• 85 kilograms lighter, body parts in carbon
• V10 FSI with 412 kW (560 hp), 0 – 100 km/h in 3.8 seconds
Even lighter, even more
powerful, even more captivating: The Audi R8 GT Spyder delivers
breathtaking performance. The open-top flagship version of the
high-performance sports car develops 412 kW (560 hp) and – thanks to
Audi ultra – has trimmed a full 85 kilograms (187.39 lb) from an
already low weight. The R8 GT Spyder accelerates from zero to 100
km/h (62.14 mph) in 3.8 seconds and reaches a top speed of 317 km/h
One year ago, Audi unveiled the R8 GT in coupe form as the new
flagship model of the R8 model line. It wasn’t long before all 333
units in the limited series were sold out. Now the open-top version
of the high-performance sports car is being launched, with
production again capped at 333 units. Each car sports a tag with its
individual number on the gear lever knob.
The Audi ultra lightweight technology is the key to the R8 GT
Spyder’s weight of just 1,640 kilograms (3,615.58 lb). That’s 85
kilograms (187.39 lb) less than its technical basis, the R8 Spyder
5.2 FSI quattro. The Audi Space Frame (ASF) body, consisting of cast
nodes, extruded sections and aluminum panels, accounts for just 214
kilograms (471.79 lb) of the total weight. The body is assembled
predominantly by hand in the R8 workshop at the Neckarsulm plant.
Final assembly of the car takes place in the same way.
The engine frame is made of ultra-light magnesium; the long cover
over the soft-top compartment and the large side panels at the rear
are made of carbon fiber-reinforced polymer (CFRP). CFRP is also
used for the modified front spoiler, the fixed rear spoiler and the
new rear bumper. Together, these components provide a weight saving
of 5.5 kilograms (12.13 lb).
Visual modifications accentuate the styling of the R8 GT Spyder.
These include add-on parts in contrasting titanium gray, a front
splitter with a dual lip, flics at the sides of the front bumper,
red GT badges, round exhaust tailpipes, an enlarged diffuser and
dark LED tail lights in a clear-glass design. Audi offers an
optional windshield frame in matt CFRP.
Audi engineers also trimmed weight from the technical components in
the area of the transmission, wheels and brakes. In the interior,
the bucket seats alone, with their chassis of glass fiber-reinforced
polymer (GFRP), saved 31.5 kilograms (69.45 lb) of weight.
In classic Audi fashion, the R8 GT Spyder features a lightweight
fabric soft top that is extremely quiet and fully suitable for
highway cruising. Its electrohydraulic drive brings it up or down in
19 seconds, even at speeds up to 50 km/h (31.07 mph). The extendible
glass rear window is nestled in the bulkhead, separate from the soft
top. Integrated in the bulkhead is a rollover protection system
comprising two pretensioned plates.
Prodigious power: the drivetrain
The performance offered
by the new top-of-the-line model in the R8 family is formidable. The
5.2-liter V10 with an aluminum crankcase draws its fuel from an FSI
direct injection system. Dry-sump lubrication ensures a reliable
supply of oil even under maximum lateral or straight-line
With its modified electronic management, the long-stroke engine
produces 540 Nm (398.28 lb-ft) of torque at 6,500 rpm, and its peak
output is 412 kW (560 hp). Each unit of horsepower has only 2.93
kilograms (6.46 lb) to move.
The R8 GT Spyder catapults from zero to 100 km/h (62.14 mph) in 3.8
seconds and reaches a top speed of 317 km/h (196.97 mph). In every
situation, the engine impresses with its thrust and bite – and that
unmistakable sound of an Audi ten-cylinder.
The R8 GT Spyder comes standard with an automated six-speed R tronic
transmission with two fully automatic modes. In the additional
manual mode, the driver can shift gears using the paddles on the
steering wheel or by flicking the joystick. At high load and revs,
gear changes take only one-tenth of a second. The launch control
program manages the starting sprint with high engine speed and
precision-control of the tire slip.
The quattro permanent all-wheel drive has a strong rear-wheel bias,
granted by the axle load distribution. If the situation calls for
it, the system sends additional torque to the front axle. In tandem
with the limited slip differential at the rear, it provides an added
measure of traction, stability and cornering speed, giving it a
strong lead over the rear-wheel-drive competition.
The suspension, too, is unrivaled in its performance. Aluminum
double wishbones locate the wheels, and the rack-and-pinion power
steering provides intimate contact with the road. Taut tuning lowers
the body by approximately 10 millimeters (0.39 in). The open
high-performance sports car has 19-inch wheels, with 235/35 tires up
front and 295/30 tires at the rear. The large, lightweight
carbon-fiber ceramic brake discs decelerate the car with supreme
ease. The ESP stabilization program has a sport mode and can also be
Pure comfort: the interior and
Great attention to
detail is evident in the materials and workmanship inside the car.
The salient aspect of the controls is their logically structured
design. The open two-seater offers a roomy interior, and its front
end can accommodate up to 100 liters (3.53 cu. ft) of cargo. The
rear bulkhead houses three storage compartments.
The interior is black and can be adorned with stitching in a choice
of titanium gray or crimson for added refinement. Alcantara
upholstery comes standard – on the sport steering wheel and
windshield frame, too.
Audi also offers leather in Fine Nappa quality. Numerous details –
including white dials and R8 GT logos – provide classy accents. The
distinctive R8 “monoposto,” a large arch encircling the driver’s
cockpit, is made of matt CFRP.
Audi ultra requires no sacrifice on the part of R8 GT Spyder owners.
The standard equipment includes LED headlights, LED tail lights, an
automatic air conditioning system, the navigation system plus, an
alarm system and the driver information system with a built-in
Audi also offers a sophisticated sound system from Bang & Olufsen
and a Bluetooth interface including a seatbelt microphone for
carrying on a phone conversation conveniently. Options specific to
the R8 GT include bucket seats with a carbon-fiber composite
chassis, matt CFRP applications and embroidered logos on the seat
The R8 GT Spyder will have a base price in Germany of 207,800 euros.
