How Will You Define Absolute Land Speed Record?

How Will You Define Absolute Land Speed Record?

The land speed record or the absolute land speed record is the highest speed achieved by a wheeled vehicle on land. Land speed record-in order to qualify as official holder of the world land speed record, a car must cover a measured distance (one mile or one kilometer) in both directions, with only a limited time allowed between runs.

The average speed achieved on the two runs is what counts. Over the years, the speed has risen from the 100 km/h (62 mph) of the earliest attempts, to the 690.9 km (429.7 mph) achieved by Donald Campbellā€™s Bluebird in 1964, which remains the highest speed by a wheel-driven car.

Since then, however, cars powered by pure jets and rockets have been allowed, and these have taken the record to over 1019 km/h (633 mph). Several organizations are now preparing to attempt to exceed the speed of sound, circa 1220 km/h (758 mph).

The current holder of the Outright World Land Speed Record is ThrustSSC, a twin turbofan jet-powered car which achieved 763.035 mph – 1227.985 km/h – over one mile in October 1997. This was the first supersonic record as it broke the sound barrier at Mach 1.016.
