Land speed record


Land speed record

The land speed record is the fastest speed achieved by any wheeled vehicle on land, as opposed to one on water or in the air or on rails. It is standardized as the speed over a course of fixed length, averaged over two runs in opposite directions. The current absolute (or unlimited) record holder is ThrustSSC, a twin turbofan jet-powered car which has achieved 763 mph (slightly under 1228 km/h) over one mile (1.6 km), breaking the sound barrier. There are also records for specific classes of vehicle, such as motorcycles (convert|350.884|mph|km/h|2|abbr=on|disp=s, currently held by Chris Carr), and steam-driven vehicles (Fred Marriott, convert|127.659|mph|km/h|2|abbr=on|disp=s), but this list only includes the absolute speed records for wheeled vehicles on ground, without rails. Early records predate standardisation and are sometimes controversial.

The ThrustSSC record was achieved by British RAF pilot Andy Green on 15 October 1997. It was set in the Black Rock Desert in Nevada, USA. Thrust Super Sonic Car's two jet engines produced a combined total of 100 thousand pounds-force (440 kN) of thrust force. During its record-breaking run, Thrust SSC accelerated to convert|600|mph|km/h|abbr=on|-1 in just 16 seconds and became the first car to break the sound barrier.
