More Power! Get the details on the potent Porsche 911 GT3 RS 4.0

Porsche has ramped up the already heady performance of the 911 GT3 RS through the adoption of a new, naturally aspirated 4.0-liter version of the company's sturdy, horizontally opposed flat six-cylinder engine. The unit kicks out 50 hp more than the 3.8-liter six-cylinder used in the existing 911 GT3 RS.

Not only does it offer economy that compares favourably with a diesel-engined car of a similar size, it suffers no performance penalty either.
