Porsche unveils range-topping 911 Cabriolets

Porsche has released the first images of the forthcoming Cabriolet versions of its 911 Turbo and Turbo S supercars.

Following closely behind the recently announced coupe variants, the Cabriolets will feature a high-quality collapsible fabric roof, chosen for its light weight and simplicity compared to a full metal item.

Drivers will be able to lift or retract it in just 13 seconds, at speeds of up to 34mph.

Both models are due to make their first public appearance at the Los Angeles motor show in November.

Sharing the same 3.8-litre twin-turbocharged six-cylinder engine, the Turbo Cabriolet develops 513bhp, with the range-topping S model developing 552bhp.

No matter which one your plump for, performance is crushing; the regular Turbo Cabriolet dispatching the 0-62mph sprint in 3.5 seconds, and the S taking just 3.2 seconds. Both cars will stop accelerating at 197mph.

Despite the power on tap, Porsche has worked hard to improve the efficiency of its flat-six motor. Fuel consumption has been reduced by 15 per cent, and both will return 28.5mpg on the combined cycle.

The cars' 231g/km CO2 emissions are also much less than similarly powerful convertible sports cars from rival manufacturers, such as the Ferrari 458 Italia and Jaguar F-Type.

Both cars are fitted with four-wheel-drive and Porsche's PDK twin-clutch automatic transmission as standard. A new magnesium roof frame also allows for similar aerodynamic properties as its fixed-roof sibling.

The Porsche 911 Turbo and Turbo S Cabriolets go on sale in December, priced from £126,766 and £149,511 respectively.
