porsche 911 turbo cabriolet

Following the reveal of the Porsche 911 Turbo and Turbo S back in May are their cabriolet counterparts, which step out of the shadows ahead of their LA show debut in November. The cars get a fabric roof with a magnesium frame that opens and closes in around 13 seconds, at speeds of up to 50 km/h. Additionally, Porsche says the roof maintains a coupe-like arch when closed.

The cars otherwise remain the same as their fixed-roof brethren – the turbocharged 3.8 litre flat-six develops 520 hp in the Turbo Cab and 560 hp in the Turbo S Cab, accelerating them to 100 km/h from rest in 3.5 and 3.2 seconds respectively before hitting a top speed of up to 315 km/h.

Fuel consumption (NEDC) is quoted at 9.9 litres per 100 km; CO2 emissions at 231 grams per km. So that means they’re 30 hp up, 0.2 seconds quicker to 100 km/h and up to 15% more efficient than their 997-series predecessors. Learn more about the 991-series Porsche 911 Turbo and Turbo S here.
