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]
Dorothy Levitt, in a 19 kW (26 hp) Napier, at Brooklands, England, in 1908. The FIA does not recognize separate men's and women's land speed records, because the records are set using motorized vehicles, and not muscle-powered vehicles, so the gender of the driver does not matter; however, unofficial women's records have long been claimed, seemingly starting with Dorothy Levitt's 1906 record ...
In 1991, JUN attended the Bonneville Speed trials at the Bonneville Salt Flats (see also Bonneville Speedway) with a Z32 Nissan 300ZX that was extensively modified. [1] JUN was able to record a speed of 422 km/h (262 mph), [ 2 ] which was a world record for a “road”-going car.
Speed Demon is a land speed racing car built in 2010 by Ron Main for George Poteet. In September 2010, George Poteet made a serious attempt to break the flying mile and flying kilometer record for piston-engined wheel-driven cars. Speed Demon is powered by a 299 cu in (4,900 cc) aluminum block 'Hellfire' V8, built by Kenny Duttweiler. [1]
In 1983 Richard Noble had broken the world land speed record with his earlier car Thrust2, which reached a speed of 1,019 km/h (633 mph). The date of Andy Green's record came exactly a half century and one day after Chuck Yeager broke the sound barrier in Earth's atmosphere, with the Bell X-1 research rocket plane on 14 October 1947.
Arfons' path led almost inevitably to land speed record racing at Bonneville, first in 1960 with the "Anteater", a car modeled after John Cobb's "Railton Special" and powered by an Allison V-1710 aircraft engine. In 1961 he reached a top speed of 313.78 mph (504.98 km/h) before burning out the clutch. Arfons sold the car to Bob Motz.
On one of the requisite two-way runs, Cobb exceeded 400 mph (640 km/h). Cobb's record would stand for 16 years, and would mark the last time that a piston-engined car would hold the world land speed record. In 1951, hot rod and drag racing enthusiast Art Arfons began building a series of aero-engined racing cars each known as the Green Monster.
