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.
