It bested the early previously to fastest, the original 1001 bhp Bugatti Veyron's 408 km/h (254 mph) but lost the title back to the French marque last year when a 1200 bhp Bugatti Veyron Wonderful Sport ran 431 km/h (268 mph) .
SSC has only just disclosed the name of the car and some images, and no doubt intends to get as much value from the project as it can by staged releases of additional intelligence over time. Hence we don't yet know what the performance figures will be for the car, but it can reasonably be expected to eclipse the Bugatti Veyron Super Cavort's 268 mph.
Traditionally, new speed records are achieved in small increments unless your name is Bugatti. The McLaren F1 held the register at 386.4 km/h (240.1mph) for seven years, before it was marginally improved to 387.87 kmh (241.01 mph) by the Koennigsegg CCR . Then followed Bugatti's 408 km/h (254 mph), the Furthest Aero TT's 412.68 km/h (256.18 mph) and then the quantum leap by the Bugatti Veyron Super Sport to 431km/h (268 mph).
