The Audi S5’s 4.2 liter V8 engine that produces 354 horsepower is more than adequate to lead the coupe segment with BMW’s 335i coupe and Infiniti’s G37 following behind. But what does Audi have planned to rival the new 2008 BMW M3 coupe? Most would jump to the conclusion that the next Audi RS 4 with a rumored 450 horsepower engine would be the perfect competitor.

However, the RS 4 is a sedan and will be a great competitor for the M3 Sedan rather than the M3 Coupe. The answer to the 2008 BMW M3 Coupe will be Audi’s upcoming RS 5, which is expected to hit the market later next year.

While no official details have been confirmed it is rumored that Audi will most likely fit the RS 5 with the same 420 horsepower V8 engine from the RS 4. Even better, Road&Track sources are saying that Audi may even look to fellow Lamborghini for the 5.2 liter V10 engine that produces 500 horsepower in the Gallardo. That should definitely leave the M3 in the dust.

Whatever the case, Audi will fit the RS 5 with Quattro all-wheel-drive and most likely offer big arse Brembo brakes. The body will take on a much more aggressive look than the S5 along with a sportier interior.

We expect some word on the Audi RS 5 at the Geneva Motor Show, but wouldn’t be surprised if it’s pushed back until Frankfurt in September next year.
