Last night I saw this Porsche 911 Turbo S Cabriolet in Tampa. This is from the 991.2 series, which has been in production since 2015. The engine is a 3.8 liter twin turbo flat-6 that produces 572 horsepower and 516 pound-feet of torque. The transmission is a 7-speed PDK. This car does 0-60 mph in 3 seconds and has a top speed of 205 mph.
