9ff style this twin-turbo 3,824cc six-cylinder explodes into an aggressive rumbling roar within 9ff's cavernous hangar style, settling down to a burbling idle through those RSR-style exhaust outlets. The man behind the car is far more serious about the speedster nameplate he has taken a Porsche 911 Carrera S Cabriolet and turned it into a turbocharged 650-horsepower monster essentially a topless version of the Porsche 911 GT2. Called the Speed 9, this car has become a 9ff model in its own right, and Fatthauer (te man behind the car) can make this concept even more elaborate, up to a 1200hp version of the 911 Turbo Cabriolet. This engine makes 650 hp at 6500 rpm and 656 pound feet of torque at 5600 rpm. This means the 2010 9ff Speed 9 is brutally fast and Fatthauer claims it'll make 100 km/h (62 mph) in 3.3 seconds and won't quit until you hit 205 mph (if you can stand the wind blast). This car is limited to 205 mph because of concerns about the topless chassis' rigidity. The prototype of the 2010 9ff Speed 9, and the production car will prove different, as it will have to accommodate a soft top to protect that interior from the rain.
