Top Gear can exclusively reveal that Shelby SuperCars (SSC) North America has set a new production car top speed record, hitting a VMAX of 331mph and setting a two-way average of 316.11mph on a seven-mile stretch of closed road just outside of Las Vegas, Nevada. Climb on board for the outrageous 0-331mph run as Top Gear is granted exclusive footage from the guys that are making the full feature-length documentary of this epic endeavour, landing later in the year.
