THE AUDI R8 V10 is powered by a Lamborghini-sourced V10, the
latest R8 sends 525 horsepower to all four wheels thanks to a sophisticated
quattro all-wheel-drive system. The car was introduced to the public at
the 2009 North American International Auto Show in Detroit.
Though sporting two more cylinders and a little more grunt mid-ship, V10-powered
R8 doesn't feature too many visual differences from its V8 sibling. More
air is fed to the ten-cylinder through larger side scoops, which jut out
sharply from the body-side, adding a more aggressive stance to go with
its increased power. The lower side sill also get an extra flare which
runs along the wheelbase, adding further visual cues that this is the
true uber-Audi. The changes are subtle enough to be obvious only to those
in-the-know, thus keeping the R8's clean lines as uncluttered as possible.
However, some subtle changes from the standard R8 will include dual oval
exhaust outlets, bigger side air intakes, a revised front and rear fascias
and larger brakes. The V10 version also sports unique LED headlights and
a rear diffuser.
The Audi
R8 was initially equipped with a 4.2 litre V8 internal combustion engine.
Specific detail: it is an all-aluminium alloy 32-valve (four valves per
cylinder) petrol engine, utilizing Fuel Stratified Injection (FSI), and
has a displacement of 4,163 cubic centimetres (254.0 cu in.) It develops
a motive power output of 309 kilowatts (420 PS; 414 bhp) and generates
430 newton metres (317 ft·lbf) of torque on 98 Super Unleaded petrol.
It is basically the same engine used in the Audi B7 RS4, but is modified
to use dry sump lubrication system. This V8 is a highly reworked, high-revving
variant from the existing 4.2 litre V8, but includes cylinder-direct fuel
injection (Fuel Stratified Injection), and four valves per cylinder, instead
of five (as used on the previous non-FSI variants). It also uses two chain-driven
double overhead camshafts (DOHC) per cylinder bank, and utilises variable
valve timing for both inlet and exhaust camshafts.
A new additional variant with a 5.2 litre Fuel Stratified Injection (FSI)
V10 engine was added on the 9th of December 2008, which produces 518 bhp.
The transmission options are either a Lamborghini sourced six-speed manual
gearbox with metal gate for the shift lever, or an Audi-developed R-tronic
gearbox - which is a single-clutch semi-automatic electrohydraulic manual
transmission, without a traditional clutch pedal.[6] These options are
the same as those available on the Lamborghini Gallardo.
Audi R8 with a V10 engine at the 2009 North American International Auto
Show. AUDI AG unveiled the Audi R8 V10 on 9 December 2008. It uses a 5.2
litre FSI internal combustion engine, based on the unit in the Lamborghini
Gallardo LP560-4 (which in turn was based on the 5.2 FSI V10 as used in
the Audi C6 S6 and Audi D3 S8), but is re-tuned to produce a power output
of 386 kilowatts (525 PS; 518 bhp), and generate 530 newton metres (391
ft·lbf) of torque. Compared to the V8 variant, the R8 V10's performance
numbers are enhanced. Audi states the new 0 to 100 kilometres per hour
(0.0 to 62.1 mph) time as only 3.9 seconds, 60 to 124 miles per hour (97
to 200 km/h) in 8.1 seconds, and a top speed of 317 kilometres per hour
(197.0 mph). Other changes to the V10 version of the R8 include some aesthetic
differences - such as all-LED headlights (a world-first), interior enhancements
such as Bang & Olufsen 465 watt sound system, and a more aggressive
body styling, larger rear brakes and unique roadwheels.
