Land speed racing is a form of motorsport.

Land speed racing is best known for the efforts to break the absolute land speed record, but it is not limited to specialist vehicles.[1]

A record is defined as the speed over a course of fixed length, averaged over two runs (commonly called "passes").[2] Under current FIA rules, two runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by at least one percent to be validated.[3] Records are set in either the flying kilometre or flying mile.[4]

History[edit]

The sport's origins date to the 1930s in California, when the Southern California Timing Association first held meets for a variety of hot rodded vehicles.

Ever since, any vehicle – car, truck, or motorcycle – able to meet the safety regulations has been able to make an attempt to break the existing record. The record is set by averaging two runs (commonly called "passes"), one in either direction, within the space of two hours.[citation needed]

All vehicles are separated by classes based on displacement. Vintage engines, like the Ford Flathead, Buick Straight Eight, Stovebolt engine and others are raced in the vintage classes.[citation needed] These consist of:

  • XF: Ford Flathead
  • XO: Overhead valve engines and non Ford flatheads built up to 1959.
  • XXF: Ford flatheads with overhead valve head conversions.
  • XXO: Overhead valve engines with specialist cylinder heads.
  • V4: Vintage four cylinder engines made before 1935. Overhead valve/Overhead cam conversions permitted.
  • V4F: Vintage flathead four cylinder engines built before 1935, valvetrain must remain a valve in block.

Women's record[edit]

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 91 mph (146.25 km/h) and receiving the sobriquet 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.[5][6][7]

A subsequent record was set by Lee Breedlove, the wife of Craig Breedlove, who piloted her husband's Spirit of America - Sonic 1 to a record of 308.506 mph (496.492 km/h) in 1965.[8] According to author Rachel Kushner, Craig Breedlove had talked Lee into taking the car out for a record attempt in order to monopolize the salt flats for the day and block one of his competitors from making a record attempt.[9]

The current women's absolute record is held by Kitty O'Neil, in the jet-powered SMI Motivator, set at the Alvord Desert in 1976.[10] O'Neil reached 512.710 mph (825.127 km/h).[11][12]

Records by class[edit]

Motorcycle record[edit]

1960–present wheel driven cars[edit]

There is no "wheel-driven" category as such.[13] The Fédération Internationale de l'Automobile validates records in a variety of classes, of which the "wheel-driven" classes are in Category A (Special cars) and Category B (Production cars). The accepted record is fastest average speed recorded over any one-mile or one-kilometer distance, averaged over two runs in opposite directions (to factor out wind) within one hour of each other. The most recent wheel-driven record holders have been from a variety of different classes within Category A.[14]

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.[15][16]

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. His car, Speed Demon, built by Ron Main, is powered by a 299 cu in (4,900 cc) aluminum block 'Hellfire' V8, built by Kenny Duttweiler.[17] Their effort was thwarted by a number of parts failures. The team stated their intention to return in 2011 to set a record over 450 mph (724 km/h), and at the 2011 Bonneville Speed Week, Poteet achieved 426 mph (686 km/h)[18]

Treit & Davenport's Viking 31

In 2012, the Target 550 team of Marlo Treit and Les Davenport planned to raise the record for this class to more than 500 mph (800 km/h) in Viking 31, built by Jim Hume. Powered by two Dodge hemis with Whipple supercharger, it has a frontal area of 8.61 sq ft (0.800 m2) and is more than 40 ft (12 m) long. The model was tested in the Western Washington University wind tunnel, with assistance from Dr. Michael Seal.[19]
