Performance is the name of the game in the Porsche 911 Turbo Cabriolet. Here the 3.8-liter’s twin-turbochargers are tuned to produce 540 hp and 486 lb-ft of torque and this will send the car to 60 mph in an amazing 2.9-seconds. For the Porsche 911 Turbo Cabriolet attention was paid to the turbochargers and the tune and so the added S sees power rise to 580 hp with 533 lb-ft of torque, and through much electronic wizardry and magic, the car has been times to hit 60 mph in as little as 2.6-seconds. It can also run the quarter in less than 11-seconds and tops out at 205 mph. Porsche’s brilliant 7-speed PDK transmission and the all-wheel drive drivetrain is found in both models.
