Porsche 911 Turbo Cabriolet price and specs

The all-new Porsche 911 Turbo Cabriolet and 911 Turbo S Cabriolet have been revealed. Both models join the recently unveiled coupe versions and will go on sale in December – straight after their public debut at the Los Angeles Motor Show.

Prices for the coupe start at £118,349 for the Turbo and £140,852 for the Turbo S, while the Cabriolet costs £126,766 and £149,511 respectively. This means the drop-top version carries a premium of around £8,500.

A six-cylinder 3.8-litre engine with two turbochargers powers both the 911 Turbo and Turbo S. In the Turbo the engine develops 514bhp, while the Turbo S engine has 553bhp.

All cars feature a seven-speed PDK automatic gearbox and a economical stop-start system, resulting in both cars claiming an impressive 29.1mpg. The Cabriolet version will do 28.5mpg – meaning the coupe and convertible models are up to 16 per cent more fuel-efficient than the cars they replace.

Despite the economy measures, performance has remained impressive. When fitted with the Sport Chrono Package Plus, the Turbo is capable of completing the benchmark 0-62mph sprint in 3.2 seconds, while the Turbo S can hit 62mph from rest in 3.1 seconds. The Cabriolet is only slightly slower, posting times of 3.5 seconds in the standard Turbo, and 3.2 seconds in the Turbo S. All variants can hit a top speed of 197mph.

Each model uses a newly developed four-wheel drive system that can send the engine's power from the front wheels to the back wheels, and vice versa, very quickly and smoothly for optimum grip.

The Turbo also features a clever rear-wheel steering system for extra stability. At speeds below 31mph, the rear wheels turn in the opposite direction to the front, giving a tighter turning circle, while above 50mph, the rear wheels turn in the same direction as the fronts to improve high-speed stability. All models get 20-inch alloy wheels, while the Turbo S has full LED headlights.

The Turbo S also benefits from Porsche's advanced chassis control, the extra performance of the Sport Chrono Package Plus, and Porsche's lightweight ceramic brakes.

Order books for the 911 Turbo and Turbo S coupe are open now, while the Cabriolet version will go on sale from December.
