While boasting high levels of performance and luxury, the 2+2 Turbo Cabriolet also impresses with its average fuel consumption of 12.9 litres/100 kms – exemplary fuel economy for a car in this segment and one that also has a top speed of 310 km/h. This is achieved through the Turbo Cabriolet’s intelligent design, outstanding aerodynamics and advanced engine technology.

As with the 911 Turbo Coupe launched in Australia in mid-2006, the Cabriolet features the same 3.6-litre twin-turbocharged boxer engine with Variable Turbine Geometry (VTG). Maximum power is 353 kW and maximum torque is 620 Nm from a low 1,950 rpm. With optional ‘Sport Chrono’ package, which includes a temporary overboost function, torque is raised to 680 Nm.

The 911 Turbo Cabriolet with six-speed manual accelerates from 0 - 100 km/h in 4.0 seconds – with Tiptronic S the sprint time is cut to 3.8 seconds, just 0.1 sec adrift of the Turbo Coupe.

Porsche engineers have kept the Cabriolet’s weight increase in check at just 70 kg over the Coupe, a result of the additional reinforcement of the chassis and inclusion of the rollover protection system behind the rear seats.

A light, three-layer soft top roof which opens or closes in 20 seconds reduces the Cabriolet’s centre of gravity to allow maximum handling potential.

The Porsche 911 Turbo Cabriolet comes standard with all of Porsche’s acclaimed chassis systems, albeit specifically tuned for the needs of the cabriolet.

Porsche Active Suspension Management (PASM) gives the Turbo Cabriolet diverse driving modes while offering an extremely high level of driving safety. Porsche Stability Management (PSM) and the all-wheel drive Porsche Traction Management (PTM) systems also optimise grip and performance.

The PTM system, with its electronically controlled multi-plate clutch, shifts the drive output from the engine between the front and rear axles. Depending on the driving conditions and grip levels, up to 100 per cent of the drive can be transferred to either the front or rear wheels.

With a CD 0.31 the drag coefficient is identical to the 911 Turbo Coupe and the Cabriolet matches the same 310 km/h top speed as its hard top sibling.

The rear spoiler raises automatically at 120 km/h – extending 30 mm further than the Coupe – with the Cabriolet the only vehicle in its class that generates negative lift at the rear axle.

The Turbo Cabriolet’s standard list of passive safety systems includes six airbags and comprehensive rollover protection system (with steel tubing integrated into the windshield frame and rollover hoops behind the rear seats).

Furthermore, it is equipped with one of the most high-performance brake systems. The six-piston front calipers are from the Porsche Carrera GT. Available as an option is the lightweight Porsche Ceramic Composite Brake (PCCB) system.

Also included in the extensive range of standard features are full leather interior, bi-xenon headlamps, 19-inch forged alloy wheels, climate control air conditioning, wind-deflector, Porsche Communication Management (PCM) with satellite navigation and 5.8-inch colour monitor and Bose Surround Sound System.
