Porshe 911 GT2 new

Ultimate 690bhp Porsche 911 GT2 RS arrives at Goodwood after making surprise debut in Los Angeles

Porsche has pulled the sheets off the most powerful 911 ever – the eagerly anticipated 911 GT2 RS. It makes its full debut at the Goodwood Festival of Speed, after a brief cameo earlier this month at the E3 gaming expo in Los Angeles.

The headline figure is the 911 GT2 RS’s enormous power output – Porsche claims that the 3.8-litre biturbo flat-six in the back produces 690bhp. It ups the ante considerably on the last generation 911 GT2 RS – previously Porsche’s most potent 911 – by making 79bhp more with its larger engine, borrowed from the 911 Turbo S and tweaked.

690bhp and 750Nm of torque is achieved through a modified turbocharging system, pushing an increased volume of air into the combustion chambers. The turbos are aided by a new and additional water-cooling system which sprays water into the charge-air cooler – this ensures air entering the combustion chambers is at an optimal temperature, even when the car is being driven hard.
