May 7, 2007 Porsche today continued its two decade tradition of soft top 911 turbos when it released details of a new 911 Turbo Cabriolet which will go on sale on September 8. The US$172,000 2+2 convertible is powered by a biturbo 3.6 liter engine with Variable Turbine Geometry (VTG) producing 480 bhp (353 kW). Porsche’s new optional “Sport Chrono Turbo Package” includes an overboost function, enabling the standard Cabriolet’s 620 Nm torque figure to be pushed to 680 Nm intermittently. 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.
While boasting the highest levels of performance and luxury, the stunning 2+2 Turbo Cabriolet also impresses with its average fuel consumption of 12.9 litres / 100 kms –exemplary fuel economy for a car with a top speed of 310 km/h. This is achieved through the Turbo Cabriolet’s intelligent design, outstanding aerodynamics and advanced engine technology.
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 911 Turbo Cabriolet comes standard with all of Porsche’s acclaimed chassis systems, albeit specifically tuned for the needs of the cabriolet. 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 head lamps, 19-inch forged alloy wheels, climate control air conditioning, wind-deflector, Porsche Communication Management (PCM) with satellite navigation and 5.8-inch color monitor and Bose Surround Sound System.
The basic price in euro for the Turbo Cabriolet is EUR 126,600 (US$172,000). In Germany the price is EUR 150,862 (US$205,000 including VAT and country-specific requirements).
