The SSC Tuatara /ˈtuətɑːrə/ is an upcoming American sports car to be produced by automobile manufacturer SSC North America(formerly Shelby SuperCars Inc.). The car is the successor to the SSC Aero and is the result of a design collaboration between Jason Castriota and SSC. Initially it was to be powered by a 6.9-liter twin-turbocharged V8 engine but eventually the capacity of the engine was reduced to 5.9-liters in order to allow the engine to have a higher redline of 8,800 rpm. SSC has stated that the power output would be at 1,350 hp (1,007 kW; 1,369 PS) (1,750 hp (1,305 kW; 1,774 PS) on E85 fuel) along with the top speed goal of 300 mph (482.8 km/h).
