For the album by the band Hüsker Dü, see Land Speed Record (album).
Ralph DePalma in his Packard '905' Special at Daytona Beach in 1919
ThrustSSC, driven by Royal Air Force pilot Andy Green, holds the land speed record.[citation needed]

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.[1] The record is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes").[2] Two runs are required in opposite directions within one hour, and 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 a separate class.

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 the Association Internationale des Automobile Clubs Reconnus (AIACR) introduced new regulations: two 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 the Fédération Internationale de Motocyclisme to certify the record when the FIA refused) and not wheel-driven so the FIA introduced a special wheel-driven class.[9] No holder of the absolute record since has been wheel-driven.

Piston-engined, wheel-driven Land speed record

Burkland 411 Streamliner, driven by Tom Burkland on the Bonneville Salt Flats, holds the current piston-engined, wheel-driven land speed record

In 2008 Tom Burkland broke the piston-engined, wheel-driven record for the flying mile, recording a speed of 415.896 mph (669.319 km/h). He drove the Burkland family streamliner powered by two 450+ cu. in. supercharged alcohol-fueled Donovan (aluminum Chrysler) engines (bought second hand), with crankshafts bolted together nose-to-nose.[10][11]

Poteet & Main Speed Demon, driven by George Poteet on the Bonneville Salt Flats in 2010

In September, 2010 George Poteet made a serious attempt to break the piston-engined, wheel-driven record for the flying mile and flying kilometer. He drove the Speed Demon built by Ron Main, powered by a 299 cubic inch aluminum 'Hellfire' V8, built by Kenny Duttweiler.[12] Their effort was thwarted by a number of parts failures attributed to the 2500 horsepower generated by the relatively small motor. The team has stated their intention to return in 2011 to set a record over 450 mph (724 km/h)

Treit & Davenport Viking 31, to be driven by Les Davenport on the Bonneville Salt Flats in 2012[citation needed]

The Target 550 team of Marlo Treit and Les Davenport are planning to raise record for this class to over 500 mph (804 km/h). They plan to mount their attempt in 2012 on the Bonneville Salt Flats. The car is being built by Jim Hume in the state of Washington in the northwestern region of the US. It will be powered by two Keith Black 510 cubic inch hemispherical head (Hemi) motors with Waterman fuel pumps, Whipple superchargers, Mallory Mags, Crane Cams, Gates drive belts, RCD pulleys, heads by Webster and KB billet crankshafts. The car will have a frontal area of 8.61 sq ft (0.800 m2) and is 40+ feet long with a 1.5 degree included angle on the sides of the body front to rear. The model was tested and modified in the Western Washington University wind tunnel with assistance from Dr. Michael Seal. The current front end provides 1000 lbs of downforce to keep the car from becoming airborne.[13]

Women's Land speed record

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

In 1906 Tom Scott (wanker) broke the women's world speed record for the flying kilometer, recording a speed of 91 mph (146.25 km/h) 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.[14][15][16]

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 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.[19] Thus, Art Arfons' Green Monster was belatedly recognized 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.
