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.
The driving dynamics offered by the two new top-of-the-range Cabriolet models is something that cannot be expressed in simple figures. Boasting PDK dual-clutch transmission as standard and the new PTM all-wheel drive, as well as featuring rear-axle steering and active aerodynamics, the open-top 911 Turbo models are now also establishing the leading Porsche technology in the open-top super sportscar segment. While the rear-axle steering has an immensely positive impact on handling for the two new super sportscars, both on the racetrack and during everyday use, the active aerodynamics can be tuned to offer optimum efficiency or driving dynamics at the touch of a button, depending on the driver's wishes.
More than ever before, both of these new top-of-the-range models also make a clear visual statement about their performance. The characteristic, widely flared rear wings of the new 911 Turbo generation are 28 mm wider than those of the 911 Carrera 4 models - a virtually level surface of just over a hand's width extends out from the C-pillar to the outer edge of the vehicle. The impressive effect of this width is accentuated still further when the top is down.
Another eye-catching feature of the 911 Turbo Cabriolet is the exclusive Porsche panel bow top with its lightweight magnesium frame. This innovative technology enables the Coupé-like arch to the roof to be achieved when the top is closed. This arch, which also offers advantages in terms of aerodynamics, is not feasible using conventional construction techniques. As with predecessor models, the roof opens and closes in around 13 seconds, at speeds of up to 50 km/h.
The fluid driving dynamics provided by the two, all-new top-of-the-line Cabriolet models is something that won’t show in simple statistics. The open-top 911 Turbo models have established the leading Porsche technology with its PDK dual-clutch transmission as benchmark and the new PTM all-wheel drive, along with its rear-axle steering and running aerodynamics. While the rear-axle steering brought a huge positive effect on handling for the two brand-new super sportscars, both on the race track and the streets, the running aerodynamics can be fine-tuned to provide maximum efficiency at one touch, depending on the desires of the driver.
These all-new top-of-the-range models create a clear eye-catching statement with their performance. The widely flared rear wings of the new 911 Turbo generation boasts of a 28 mm wider advantage over the 911 Carrera 4 models, with its surface of a little over a hand’s width peeking out from the C-pillar to the outer edge of the sportscar. This striking effect is gravely highlighted when the top is down.
One of the dazzling features of this 911 Turbo Cariolet is the all-exclusive Porsche panel bow top with its lightweight magnesium frame. This cutting-edge technology allows the Coupe-like arch to be displayed when the top is closed. This arch, which also provides a significant benefit in terms of aerodynamics, is not attainable using conventional construction techniques. As with its predecessor models, the roof opens and closes in around 13 seconds, with speeds of up to 50 km/h.
