Porsche will celebrate the 50th anniversary at the 2013 Frankfurt Motor Show (IAA) in September and according to our sources, the German manufacturer will bring the all-new 911 (991) Turbo and Turbo S Cabriolet models. In terms of design, the new Porsche 911 Turbo and Turbo S Cabrio will not bring something different from the design seen on the coupe versions.
The only change will be the soft top. Under the hood, we will find the 3.8-liter six-cylinder engine with direct petrol injection that develops 520 hp on the Turbo and 560 hp on the Turbo S model. The open-top versions of the Turbo and Turbo S are expected to have the same fuel consumption like the coupes, just 9.7 l/100 km.
The Porsche 991 Turbo Cabriolet is expected to sprint from 0 to 100 km/h (62 mph) in just 3.2 seconds, while the 991 Turbo S Cabriolet will reach the same speed in 3.1 seconds. Both vehicles are expected to have a top speed limited at 318 km/h or 197.5 mph.
Both cabriolet models will also get the new rear axle steering that made its debut on the coupes. For those who don’t know, the steering angle of the rear wheels can be varied by up to 2.8 degrees, depending on vehicle speed. At speeds up to 50 km/h, when the front wheels are turned, the system steers the rear wheels in the opposite direction.
