Here we go, the Audi R8 taken to the next level, now powered by a V10 engine! Many an Audi R8 prototype cars have been sacrificed for this car to be finally unveiled today. Audi had experimented with the 580hp turbocharged V10 from the Audi RS6 in the R8’s snug engine bay and naturally the prototypes experienced overheating problems. A total of 3 prototypes have burned down to part car, part ash as of November last year.
So anyway clearly that did not work, despite Audi powertrain boss telling Autocar UK earlier this year that they’ve solved the overheating problems thanks to some innovations which also appeared on the Audi R8 V12 TDi Concept. But diesel engines usually run colder than petrol engines. Maybe it didn’t end up viable after all.
So this new more high powered you see here is powered by a normally aspirated V10. The Audi R8 5.2 FSI quattro’s engine is similiar if not the same as the 5.2 litre FSI V10 found in the Lamborghini Gallardo LP560-4. However it is detuned as it makes less power: 525hp at 8,000rpm and 530Nm at 6,500rpm compared to the LP560-4’s 560hp and 540Nm. But like the unit in the Gallardo, it sends power to all four wheels. 0 to 100km/h takes 3.9 seconds and the car goes on to a top speed of 316km/h.
The 5.2 litre FSI V10 long-stroke engine uses a dry sump lubrication system, which allows the engine to be mounted low in the engine bay, helping lower center of gravity. The engine itself has a low center of gravity thanks to the 90 degree cylinder angle. The crankcase is made of high-strengh aluminium alloy, the conrods of forged steel and the pistons of aluminium. The car’s weight distribution is what Audi calls an ideal 44:56. I wonder what has BMW and their 50:50 have to say about that.
Two transmissions are available, a 6-speed manual or a single clutch automated manual called the R-Tronic which I suspect is similiar to Lamborghini’s E-Gear automated manual. Both R-Tronic and the manual versions have a Launch Control feature which takes the car off the starting line as fast as possible with tire slip reined in to a minimum electronically. quattro all-wheel drive also helps out with this.
Brakes are large 380mm brakes at the front and 356mm brakes at the rear, which are all ventilated and are gripped by large 8-pot calipers at the front and 4-pot calipers at the rear. Optional is a ceramic brake system which is made of a composite material containing high-strength carbon fibers and abrasion-resistant silicon carbide. These brakes are 9kg lighter than the set of standard brakes, and cope better with racing requirements.
The Audi R8 5.2 FSI quattro suspension design uses double wishbones made of aluminium at both the front and rear. The shocks feature Audi magnetic ride as standard, which adapts the damping characteristics within milliseconds according to road conditions and driving style. Audi magnetic ride uses magnetic particles in the shock absorber’s oil which rearrange themselves to slow down the flow of oil through the valves when a voltage is applied.
