2008 Porsche 911 Turbo Goes Topless
2008 Porsche 911 Turbo Cabriolet
Scheduled to go on sale in September, the new Porsche 911 Turbo Cabriolet will take its rightful place at the top of Porsche’s sports car hierarchy and will continue Porsche’s 20-year tradition of offering an open-top turbocharged 911 sports car for those who yearn for the ultimate open-air Porsche driving experience either on the track or on the boulevard.
The 911 Turbo Cabriolet features the same 3.6-liter, six-cylinder, twin-turbocharged boxer engine found in the 911 Turbo Coupe. Using Variable Turbine Geometry (VTG), the powerplant generates 480 horsepower and 460 lb-ft of torque at 1950 rpm.
The heart of the Variable Turbine Geometry technology is the turbocharger’s adjustable guide blades, which can vary in angle to most effectively guide engine exhaust flow onto the turbocharger’s impeller wheel. The result is a system that provides the advantages of both a small and large turbocharger, thus eliminating the turbo lag or old and, instead, offering unheard of flexibility and awesome acceleration, particularly at low engine speeds.
The optional Sport Chrono Package Turbo allows a 10-second, mid-rpm-range overboost, temporarily increasing turbo boost under full throttle and swelling peak torque to 505 lb-ft. The manual transmission version can accelerate from 0 to 60 mph in 3.8 seconds (0 to 100 km/h in 4.0 seconds), while the Tiptronic® S version covers the same distance in 3.5 seconds (0 to 100 km/h in 3.8 seconds). Both versions can reach a top test-track speed of 193 mph (310 km/h).
