NEW POWER GENERATION

Under the giant tail sits an enhanced version of the 3.8-litre twin turbo lat-six already busy in the Turbo and Turbo S. The turbos themselves are the same but maximum boost is increased, a water spray for the charge cooler kicks in at high temperatures and an extra lightweight titanium exhaust means bigger sounds and saves 7kg over the standard item. All that gives 991 GT2 RS a 37lb ft and 79bhp advantage over the last one.
