"We want to show that we can deliver a high-powered naturally aspirated engine,’ Audi engine boss, Wolfgang Hatz, told Autocar’s German sister publication auto motor und sport."

 

Newest rumors indicate a normally aspirated 420-HP 4.2L V8.

 

Yes, no more turbo in the RS-series.

 

Assuming they also keep the S4 for the next generation, it seems pretty stupid to have a 4.2 N/A in both that and the RS4, even with ~ 80 hp difference. I would be happy with the RS6 motor in a new RS4. But then RS6 numbers would have to be ridiculous, well more ridiculous than the 500hp E60 M5 of course

 

The next RS6 is supposed to have a V10 (which it really would have to, to compete with the M5). Audi can easily get a V10 from the Gallardo.

I do agree with you about the NA V8 - seems silly to me, too.

iF IT HAPPENS THAT CAR WILL BE AWESOME!

AND MOSTLY LIKELY IT WILL.

 

Cosworth built the 4.2 in the B6 S4. I'm pretty sure they're the ones who are making the engine for the RS4.
