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.
