Audi R8 5.2 FSI quattro

Audi is launching the next variant of its top-of-the-line model. With the R8, the brand has established itself at the forefront of high-end sports cars from the very start - and now comes the R8 V10. Its 5.2-liter, ten-cylinder engine churns out 386 kW (525 hp) and 530 Nm (390.91 lb-ft) of torque, which makes for breathtaking performance. With superior Audi technologies such as quattro all-wheel drive, the lightweight aluminum body, the innovative all-LED headlights, and its striking design, the R8 V10 takes pole position against the competition.

The R8 V10 is the result of cumulative know-how from Audi’s string of Le Mans victories. Its naturally aspirated engine combines racing technology such as dry sump lubrication with FSI gasoline direct injection. The ten-cylinder design is the perfect synthesis for impressive top performance, mighty pulling power, and low weight. Starting in 2009, this engine will also prove its potential on the world’s racetracks - in the new R8 racing car Audi is developing for customer teams in conformance with the GT3 rules.

The V10 engine in the production sports car will be almost identical in construction to the one in the racing version. Its displacement is 5,204 cc, at 6,500 rpm it delivers 530 Nm (390.91 lb-ft) of torque, at 8,000 rpm its power tops out at 386 kW (525 hp).

The specific power output is 100.9 hp per liter of displacement - and each hp has to propel only 3.09 kilograms (6.91 lb) of weight, because the Audi R8 V10 in the version with the six-speed manual gearshift weighs only 1,620 kilograms (3571 lb). The engine accounts for 258 of these kilograms (569 lb) - that’s only 31 kilos (68 lb) more than the V8.

The Audi R8 5.2 FSI quattro rockets from zero to 100 km/h (62.14 mph) in 3.9 seconds. In the version with the sequentially shifting R tronic it reaches 200 km/h (124.27 mph) in another 8.1 seconds. Even then its propulsive power hardly lessens: it’s sufficient to reach a top speed of 316 km/h (196.35 mph). The immense force, the spontaneity and the thrust of the acceleration, plus the sound of the engine - all these impressions coalesce into a breathtaking sports car experience. The V10 plays a concert with growling bass tones and powerful high notes, which grows into a grandiose fortissimo as the engine revs up. This sonorous acceleration doesn’t reach its limit until 8,700 rpm.

The 5.2-liter powerplant uses direct injection according to the FSI principle developed by Audi. A common rail system injects the fuel into the combustion chambers with up to 120 bar of pressure. Direct injection reduces the susceptibility to knocking and provides a certain amount of cooling through the evaporation of the fuel, which in turn supports a high compression ratio of 12.5:1. This in turn contributes to superior performance and improves fuel economy. The R8 V10 with R tronic gets by on an average of 13.7 liters per 100 km (17.17 US mpg).

Audi R8 GT3 Le Mans at Essen Motor Show

2008-11-29 / author : lmpcars

audi_r8_gt3_lm_002-1128-950x673Audi R8 GT3 Le Mans at Essen Motor Show
Audi’s motorsport division announced plans back in August to launch a 500hp-plus (373kW) version of the R8 for use in next year’s GT3 series, and today the car made its debut at the Essen Motor Show in Germany.

The new car has been designed for private customer teams and fully conforms to the production-based GT3 regulations, which means they will be allowable in numerous national and international competitions.

Because the GT3 regulations prohibit the use of AWD, the Audi R8 comes with a modified RWD powertrain and a newly developed six-speed sequential sports gearbox. The suspension is almost completely stock, with most of the modifications focusing on weight reduction and improving the car’s aerodynamics package. A modified front end and a large rear-wing generate the required downforce for the race track.
