The the state land speed record (quantified over one-mile) is 1,227.985 km/h (763.035 mi/h) (Mach 1.020), set by Andy Green (United Kingdom) on 15 October 1997 in the Black Rock Desert, Nevada, United States, in Thrust SSC. It’s also one of the most expensive cars ever built.
Even though Thrust SSC is the primary car to break the sound barrier, it’s claimed that Budweiser Rocket Car, powered by Stan Barrett (United States), achieved a rate of 1,190.377 km/h (739.666 mi/h) at Edwards Air Force Base, California, United States, on 17 December 17 1979. On the other hand, the published rate of Mach 1.0106 had not been formally approved by the USAF, as the Digital Instrument Radar had not been adjusted or licensed. The information wasn’t created utilizing the car by an agent training a plate by means of a Television display although right.
The automobile is driven by two Rolls-Royce Spey 202 aircraft motors which create 222 kN (50,000 pounds) of thrust.
