After months of spy shots, Porsche has finally lifted the veil on the 911 Turbo Cabriolet. As with the 911 Turbo Coupé, the Cabriolet will also be powered by a 3.6L six-cylinder ‘boxer’ engine with biturbo turbocharging and Variable Turbine Geometry (VTG). The powerplant already generates 480hp (353kW) and 620Nm of torque at a low 1950 rpm.

The manual transmission version can accelerate from 0 to 100 km/h in just four seconds, while tiptronic owners get to go a little faster at 3.8 seconds. Both versions can reach speeds of up to 310 km/h, making it one of the fastest cabrios in the world.

Despite the added chassis reinforcement rollover protection specifically for this model, the open version of the 911 Turbo only weighs 70 kilos more than the coupe. Porsche also claims the three-layer soft top allows the car to have a low c-of-g. Buyers will be able to transform the car to open mode in 20 seconds.

With a drag coefficient of 0.31, the 911 Turbo Cabriolet is aerodynamically similar to the coupe. Together with the rear spoiler, which automatically extends at speeds from 120 km/h the vehicle is the only standard series convertible that generates negative lift at the rear axle. The spoiler extends 30mm further than with the coupe.

Apart from this, the usual Porsche Turbo AWD system and the option of carbon ceramic brakes are also available. Porsche will be officially unveiling the model on September 8th, so buyers will still have to wait a little while to get their hands on it.
