AUDI R8 Engine

Audi R8 Engine The figures illustrate the outstanding potential of the eight-cylinder unit. At 7,800 rpm the 4.2-liter engine delivers 420 bhp of power output. Peak torque is 317 lb-ft from 4,500 to 6,000 rpm. And no less than 90 per cent of this maximum torque is maintained consistently throughout a wide engine speed range from 3,500 all the way to 7,600 rpm.

As a result of these qualities, the eight-cylinder power unit provides maximum thrust in virtually any driving situation. The performance figures are equally impressive: the R8 accelerates from a standstill to 60 mph in 4.4 seconds and reaches a top speed of 187 mph.

The 5.2 liter twin turbocharged FSI direct injection V10 in the RS6 puts out a constant 580 horses between 6,250rpm and 6,700rpm, and a collosal 650Nm of torque from a very low 1,500rpm all the way up to 6,250rpm. This is a very very scary engine indeed.

Autocar UK confirms that the RS8 has been signed off and approved for production, and we will be able to see some form of glimpse of it by Q2 2009.

Cooling for the twin turbocharged engine will be via design modifications that will provide extra cooling to the engine bay, including NACA roof air ducts for the turbos. NACA ducts get their name from its developer, the National Advisory Committee for Aeronautics (which eventually ended up as NASA). This is not the first time Audi will be stuffing a turbocharged engine into the R8′s engine bay, as it has done it before with the Audi R8 V12 TDI, so there has been constant cooling know-how gained over time.
