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.
