The era of the naturally aspirated V8 engine will soon come to an end. Sure, you may see them from time to time in something like a Wiesmann, but mainstream automakers are dropping them faster than they are manual transmissions. Audi, BMW, Mercedes...each one is replacing those old school V8s with twin-turbocharged engines all in the name of improved fuel economy.

But for now, there are still a few naturally aspirated V8 survivors, and two of them are the Audi RS5 and the Mercedes-Benz C63 507. With 957 hp between them, there several differences, such as the all-wheel-drive versus rear-wheel-drive. Watch as Motor Trend gets behind the wheel of each one for one hell of a blitzkrieg head to head.
