Land speed record

ThrustSSC, driven by Royal Air Force pilot Andy Green, holds the current land speed record

The land speed record (or absolute land speed record) is the fastest speed achieved by any wheeled vehicle on land. There is no single body for validation and regulation; what is used in practice is the Category C ("Special Vehicles") flying start regulations, officiated by regional or national organizations under the auspices of the Fédération Internationale de l'Automobile.^[1] The record is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes")^[2]. Previously, the two runs were required in opposite directions within one hour, however due to a fatal return-run accident at Bonneville Speed Week, the two runs are now conducted in the same direction, with the second run done the morning of the next day. A new record mark must exceed the previous one by one percent to be validated.^[3] There are numerous other class records for cars, and motorcycles fall into another, separate, class. The current absolute record holder is the British designed ThrustSSC, a twin turbofan-powered car which achieved 763 miles per hour (1,228 km/h) for the mile (1.6 km), breaking the sound barrier.

Until 1906, the rail speed record exceeded the auto speed record. However, the current unmanned record is held by a railed vehicle and stands at Mach 8.5.^[4]

History

The first regulators were the Automobile Club de France, who proclaimed themselves arbiters of the record around 1902.^[5]

Different clubs had different standards and did not always recognise the same world records^[6] until 1924, when Association International des Automobile Clubs Reconnus (AIACR) introduced new regulations: 2 passes averaged with a maximum 30min (later more) between runs, average gradient of the racing surface not over 1%, timing gear accurate within 0.01sec, and cars must be wheel-driven.^[7] National or regional auto clubs (such as AAA and SCTA) had to be AIACR members to ensure records would be recognized.^[8] The AIACR became the FIA in 1947. Controversy arose in 1963. Spirit of America failed on being a three-wheeler (leading Fédération Internationale de Motocyclisme to certify the record when FIA refused) and not wheel-driven, but the general public did not care^{[citation needed]}, so FIA introduced a special wheel-driven class.^[9] No holder of the absolute record since has been wheel-driven. Ben davies holds the land speed record

Women's Land speed record

Dorothy Levitt, in a 26hp Napier, at Brooklands, England in 1908

In 1906 Dorothy Levitt broke the women's world speed record for the flying kilometer, recording a speed of 90.88 mph (146.25 km/h) of 91 mph and receiving the soubriquet the "Fastest Girl on Earth". She drove a six-cylinder Napier motorcar, a 100 hp (74.6 kW) development of the K5, in a speed trial in Blackpool.^[10][11][12]

1963 – present (jet and rocket propulsion)

Craig Breedlove's mark of 408.312 miles per hour (657.114 km/h), set in Spirit of America in September 1963, was initially considered unofficial. The vehicle breached the FIA regulations on two grounds: it had only three wheels, and it was not wheel-driven, since its jet engine did not supply power to its axles. Some time later, the Fédération Internationale de Motocyclisme created a non-wheel-driven category, and ratified Spirit of America 's time for this mark.^[9] On July 27 1964, Donald Campbell's Bluebird CN7 posted a time of 403.10 miles per hour (648.73 km/h) on Lake Eyre, Australia. This became the official FIA LSR, although Campbell was disappointed not to have beaten Breedlove's time. In October, several four-wheel jet-cars surpassed the 1963 mark, but were eligible for neither the FIA nor FIM ratification. The confusion of having three different LSRs lasted until December 11, 1964, when the FIA and FIM met in Paris and agreed to recognize as an absolute LSR the higher speed recorded by either body, by any vehicles running on wheels, whether wheel-driven or not.^[15] Thus, Art Arfons' Green Monster was belatedly recognised as the absolute LSR holder, while Bluebird held the now-separate wheel-driven land speed record, and Spirit of America the tricycle record. Since then, no wheel-driven car has held the absolute record.
