Porsche has revealed a new convertible version of its 911 Turbo set to go on sale in September. The open top 911 Turbo weighs 154lbs. more than the coupe, largely due to reinforcements in the chassis, convertible body and automatic extendable rollover protection behind the rear seats. The three-layer fully-automatic soft top contributes to a low center of gravity and can be raised or lowered in 20 seconds. The Cabriolet is powered by the same 3.6 liter twin turbocharged six-cylinder as hardtop variants, ca
pable of generating 480bhp and 457lb-ft of torque. Up to 501lb-ft of twist is available if the box labeled "Sport Chrono Turbo Package" is ticked off the options list. Contrary to traditional figures, the semi-automatic Tiptronic S propels the car to 62mph in 3.8 seconds, two-tenths quicker than its manual counterpart. A 193mph top speed is identical for both manual and Tiptronic-equipped cars.
The 911 Turbo Cabriolet is a highly aerodynamic car, with a drag coefficient of just 0.31Cd. The active rear spoiler - which extends 30mm further than that of the coupe - is automatically extended at speeds above 75mph to generate negative lift at the rear axle. The front wheels are fitted with high-performance brake calipers derived from those found on the range-topping Carrera GT.
