Power from the 911 Turbo’s twin-turbocharged, 3.8-litre flat six engine has been increased in the Turbo S to 523bhp, up from 493bhp. Its torque output has also been increased by 37lb ft, to 516lb ft. Despite these increases, combined fuel economy remains at 24.8mpg.
Power is sent to all four wheels through a seven-speed PDK dual-clutch gearbox in conjunction with Porsche’s Traction Management system. Wheel-mounted paddle shifters are included as standard for the first time in a 911. Porsche’s Torque Vectoring system, which includes a mechanical limited-slip differential, is also standard.
