New Audi RS6 to get 572bhp V8

The 2013 Audi RS6 looks set to swap its V10 for the new Audi V8 with the wick turned up to 572bhp – the same as the old V10.

Carbon fiber's cost is falling dramatically, thanks to production advances that let suppliers speed the material's finicky, and costly, curing process. One technological breakthrough that makes carbon-fiber auto parts more affordable may come from a process used to make carbon-fiber golf clubs.
