Remember the Audi R8 prototype that burned to the ground? It was all part of the painful (for us to watch the R8 test cars burn down) engineering process that has let Audi finally announce this – the upcoming Audi RS8 will come with the RS6’s twin turbocharged V10.
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.
The 5.2 litre 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.
