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).
