Shelby has released some official video of its new supercar, the Tuatara. 

One of the most famous names in American performance cars, Shelby is a former holder of the world's fastest production car title - that was with its 1,183HP SCC Ultimate Aero TT that recorded a top speed of 257 mph. The 258mph Bugatti Veyron Super Sport topped that, but now Shelby is back for revenge

Styled by Saab's current design boss, Jason Castriota, the Tuatara will use a 1,331bhp twin-turbo 7.0-litre V8, sending power to the rear wheels through a seven-speed manual or a seven-speed robotised manual gearbox. Performance figures are yet to be released but the aim is clear - to surpass the Super Sport's 258mph top speed.

The name Tuatara actually refers to a type of reptile, native to New Zealand. It supposedly has the fastest evolving molecular structure in nature, something that the company's owner, Jarod Shelby, feels it shares with his carbon-fibre-bodied supercar.
