Now even more powerful, lighter and more quickly: Audi R8 Audi presents the GT – a limited production version of the Audi R8 high-performance sports car. Output from the 5.2-liter V10 has been increased to 412 kW (560 hp), weight of vehicles has been reduced by approximately 100 kilograms (220.46 pounds). Audi R8 GT accelerates from zero to 100 km / h (62.14 mph) in 3.6 seconds and reaches a top speed of 320 km / h (198.84 mph).
The R8 high-performance sports car is a winner right from the beginning. This applies to both the production model, winner of the “World Performance Car” Award in 2008 (R8), and 2010 (R8 V10), and racing cars, LMS R8, which won 23 races in his first season and claimed three championships. The genes from the version now comes to road racing – the Audi R8 GT. Exclusive range is limited to 333 units. Every GT Audi R8 has a badge with a total production over the shifter lever.
The use of consistent lightweight 100 kg (220.46 pounds), trimmed

Production Audi R8 5.2 V10 FSI quattro has been a good example of Audi’s philosophy of lightweight construction. Its aluminum Audi Space Frame (ASF) body weighs just 210 kilograms (462.97 pounds). aluminum body panels are connected to the chassis with extruded
ASF body is mainly made by hand at the Neckarsulm plant in the complex manufacturing process. Very high body strength is the basis for precise manipulation of high-performance sports cars, and also provide comfort and crash safety chip good vibrations.
Glass front of the Audi R8 GT are made of thin glass, the partition between the cockpit and engine compartment, and a window on the tailgate is made from polycarbonate light. These three changes saved nine kilograms (19.84 pounds). Rear wing remains good for about an additional 1.2 kg (2.65 pounds) more smooth shave cutting plates and an additional 2.6 kg (5.73 pounds) of aluminum doors in the trunk of 100 liters Baggage (3.53 cubic feet) in front of the car.
Long rear hatch is made of plastic reinforced with carbon fiber (CFRP) – a gain of 6.6 kilograms (14.55 pounds). Rear bumper and sideblades from the same material and save some extra 1.5 5.2 kg (11.46 pounds and 3.31), respectively. With a very low weight and high strength, CFRP is an ideal material for high performance sports cars, and Audi has extensive expertise in its use.
Engineers are also striving to shave every gram of weight as possible from the technical components of R8. They shaved one kilogram (2.20 pounds) of electric braking system, four kilograms (8.82 pounds) of aluminum cap from the brake discs and 9.4 kilograms (20.72 pounds) batteries. The engineers also found 2.3 kilograms (£ 5.07) at the inlet module and 2.8 kg (£ 6.17) in isolation from the engine compartment.
interior also contains great potential for weight gain. The new, lightweight carpets account for 7.9 kg (17.42 lbs) bucket seat with a frame of reinforced plastic (GRP) account for 31.5 kilograms (69.45 pounds). Many detailed other steps inside, outside and technology, as a superior, mild steel for the exhaust pipes of the system.
Even stronger and more effective design
The design of the Audi R8 GT is an expression of concentrated power – a statue of a beautiful technique for measuring 4.43 meters (14.53 feet) long, 1.93 m (6.33 ft) wide and only a 24-meter (4.04 feet ) high. exterior has undergone many changes highlight the display. Many of them also reduce weight and improve aerodynamics. Audi R8 GT generate more support when driven faster than the production model – with no increase in the value of Cd (0.36) or frontal area (1.99 m2) (21.42 m²).
The lattice of a single image frame, legs and ribs on the ventilation is completed within the titanium matte gray, the grid is painted matte black. Separator under the bumper has a double lip and made of carbon. Sleek, curved at the corner of the police to increase downforce on the nose and front axle are also made of carbon fiber composites.
One of the strengths of Audi R8 GT LED lights are standard, using LEDs for all functions. They produce bright light and homogeneous, has a long life and low energy consumption. Lighting also has an attractive and distinctive appearance. Daytime running lights each including 24 LEDs and appear as a continuous band. The reflectors are reminded open clam shells.
Factors that determine the side view is sideblades, which direct air to the engine in the Audi R8 GT also the carbon mast. The same materials used for small residential side mirrors, mounted on aluminum base. 19-inch wheels come with an exclusive design of the five fingers with an expression of the double Y-titanium. Sports front wings “GT” badges.
Changes to the rear of the car is very visible, starting with a fixed carbon wing mast. Holes on either side of the rear bumper and hatch CFRP incorporating the exhaust pipe of a large round vents and wheel arches have been redesigned. Largest broadcaster is the composite carbon fiber rear license plate and the blade width at the back of matte gray titanium. Rear lights, which also uses LED technology, the house with black glass window clear.
R8 GT offers a choice of four colors: Orange Metallic Samoa, Suzuka gunmetal, Ice Silver Metallic Phantom Black Pearl.
Liver Strength: 412 kilowatts (560 hp) 5.2 FSI
Changes in V10, the breech is painted red door, Audi R8 GT gives the performance of the heart. The R8 GT sprints from start up to freeway speed in 3.6 seconds and from zero to 200 km / h (124.27 mph) in 10.8 seconds. And the surge does not leave until the top speed of 320 km / h (198.84 mph) is reached.
Changes to persuade the 26-kilowatt engine electronic additional ten-cylinder, which now produces 412 kilowatts (560 hp) from a displacement of 5204 cc. Torque curve peaks at 540 Nm (398.28 pounds ft) at 6,500 rpm, 10 Nm (£ 7.38-ft) higher than the production version. This V10 has a specific output of 79.2 kilowatts (107.6 bhp) per liter displacement. Power to weight ratio is 3.70 kg (8.16 pounds) per kW, or 2.72 kg (6.00 pounds) per horsepower. RedLine 8700 engine rpm.
Long stroke engine (subject to x stroke 84.5 x 92.8 mm [3.33 x 3.65]), which is handmade in a factory in Gyor, Hungary, with an aluminum-silicon alloy casing is lightweight and very strong both . A bench trial – a framework for the crankshaft bearing bridge – which have further strengthened stiffness. Complete engine weighs just 258 kilograms (568.79 pounds). This is marked with 90-degree cylinder angle and even dry lubrication, using oil pump module is very efficient. The second option would be to lower the center of gravity and thus improve driving dynamics.
crankshaft is designed as a common pivot axis. Engage the piston rod against the public, so that alternating intervals of shooting 54 and 90 degrees. This provides a unique rhythm V10 sounds very interesting – a music, great technical resembles the race. Two components of a sewage system to adjust the volume and tone depending on load and engine speed.
Normally aspirated engine uses an average of 13.7 liters of fuel per 100 km (17.17 U.S. mpg) – fuel economy very good given great strength. FSI petrol injection system injects fuel directly into the combustion chamber pressures up to 120 bar. Turbulent mixing cool the cylinder walls, which allows the compression ratio to 12.5:1. A variable intake manifold and hold the chain driven camshafts are adjusted to ensure that the combustion room is filled. Flaps on the intake ports to facilitate formation of a mixture to produce a rocking motion of the air flow.
Powertrain: traction without compromises
Shifts in the Audi R8 GT managed by R Tronic sequential manual. Electro-hydraulic clutch and switching units to receive their orders electronically. Changed from a six-speed is much faster than an experienced driver can – in a tenth of a second high load and engine speed.
Electronic management system offers an automatic with sport and normal characteristics, and two manual level. This short shifter is controlled using a lever on the central tunnel and two paddles in the steering wheel. Maximum puncture start is ensured by the Launch Control – a program that is running at full speed with high engine speed and wheel spin at least at startup.
tech all-wheel quattro permanent-is ideal for high performance sports car. Viscous coupling center differential located ahead of sending 15 percent of power to the front axle and 85 percent to the rear wheels in normal driving. The division is aligned with the distribution of GT Audi R8 to 43:57 weight percent. clutch send as many as 30 percent of power to the front wheels in a few milliseconds, if any. A mechanical differential locking rear wheels to improve traction. This provides up to 25 percent closed during acceleration and up to 40 percent in the attack.
Chassis more tense and more precise
