Thrust SSC (SuperSonic Car) is a British designed and built jet-propelled car developed by Richard Noble, Glynne Bowsher, Ron Ayers and Jeremy Bliss, which holds the world land speed record, set on October 15, 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier, not considering the earlier but unofficial claim of the Budweiser Rocket.
The car was driven by Wing Commander Andy Green in the Black Rock Desert in Nevada United States. It was powered by two afterburning Rolls-Royce Spey engines as used in British F-4 Phantom II jet fighters. It is 16.5 m (54 ft) long, 3.7 m (12 ft) wide and weighs 10.5 tons (10.7 t). The twin engines developed a thrust of 223 kN (50,000 lbf) and burned around 4 Imperial gallons per second (18.2 l/s or 4.8 US gallons/s). Transformed into the usual terms for car mileages based on its maximum speed, the fuel consumption was about 5,500 l/100 km or 0.04 mpg U.S.
