The land speed record (or absolute land speed record) is the highest speed achieved by a wheeled vehicle on land. There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used, officiated by regional or national organizations under the auspices of the Fédération Internationale de l 'Automobile. The record is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes"). Two runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by one percent to be validated. There are numerous other class records for cars; motorcycles fall into a separate class.
What is the fastest speed at which anyone has ever travelled on Earth?
The Thrust SSC (Super Sonic Car) is a British jet-propelled car developed by Richard Noble, Glynne Bowsher, Ron Ayers and Jeremy Bliss and it is also the fastest vehicle to ever travel on land. The Thrust SSC holds the World Land Speed Record, set on 15 October 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first car to officially break the sound barrier at Mach 1.02. The speed of sound is estimated to be roughly around 740 MPH, but varies depending on temperature and elevation.
The car was driven by Royal Air Force fighter pilot Wing Commander Andy Green in the Black Rock Desert in Nevada, United States. It was powered by two afterburning Rolls-Royce Spey turbofan engines, as used in the British version of the F-4 Phantom II jet fighter. The car was 16.5 m (54 ft) long, 3.7 m (12 ft) wide and weighed 10.5 tons (10.7 t), and the twin engines developed a net thrust of 223 kN (50,000 lbf), a power output of 110,000 bhp (82MW), burning around 18 litres per second (4.0 Imperial gallons/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
