Some 50 years after the 911 first made its debut and to coincide with the 40th anniversary of the 911 Turbo, the open-top versions of the 911 Turbo and 911 Turbo S are making their global debut. The vehicles will be unveiled for the first time at the Auto Show in Los Angeles on November 20. By adding the two new 911 models into the mix, Porsche is doubling its offering of the top-of-the-range models to four versions.
The turbocharged 3.8-litre six-cylinder engine delivers 520hp (383 kW) in the open-top 911 Turbo and 560hp (412 kW) in the S model. The cars accelerate from zero to 62mph in 3.5 and 3.2 seconds respectively, reaching a top speed of up to 198mph.
Porsche claims fuel consumption figures are below the ten-litre limit, with both new Cabriolet models achieving figures of 28.5mpg. When compared against the respective predecessor models, the new vehicles deliver 30hp more power and are 0.2 seconds faster in terms of their standard acceleration. They are also up to 15% more efficient, says Porsche.
Both models also feature PDK dual-clutch transmission as standard and the new PTM all-wheel drive, as well as rear-axle steering and active aerodynamics. While the rear-axle steering improves impact on handling, the active aerodynamics can be tuned to the the driver’s demands.
Styling-wise, the characteristic, widely flared rear wings of the new 911 Turbo generation are 28 mm wider than those of the existing 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 width is accentuated still further when the top is down.
Another feature of the 911 Turbo Cabriolet is the Porsche panel bow top with its lightweight magnesium frame. This enables the coupe-like arch to the roof to be achieved when the top is closed. This arch 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 31mph.
The new convertible models will be launched onto the market in December 2013.
