Information: - The land speed record (or absolute land speed record) is the highest speed achieved by a person using a 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 Federation Internationale de l'Automobile. The land speed record (LSR) is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes"). 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. There are numerous other class records for cars; motorcycles fall into a separate class. - The Federation Internationale de l'Automobile (FIA, English: International Automobile Federation) is an association established as the "Association Internationale des Automobile Clubs Reconnus" (AIACR, English: 'International Association of Recognized Automobile Clubs') on 20 June 1904 to represent the interests of motoring organisations and motor car users. To the general public, the FIA is mostly known as the governing body for many auto racing events. The FIA also promotes road safety around the world. - Charles Raymond Keech (born May 1, 1900 in Coatesville, Pennsylvania - June 15, 1929) was a board track and brick track racer in the 1920s. He is best remembered for winning the 1929 Indianapolis 500, and for setting a land speed record. - The White Triplex ( also known as Triplex Special and Spirit of Elkdom ) was a land speed record car built for J. H. White and driven by Ray Keech . It was powered by three 27 - litre Liberty aero - engines , for a total of 36 cylinders , 81 litre displacement and a claimed 1500 bhp . A wealthy American , J. H. White of Philadelphia ( unrelated to the White Motor Company ) , wanted to take the land speed record from the British , then shared in a duel between Henry Segrave and Malcolm Campbell . No suitable engines were available to give a sufficient advantage over the British Napier Lion , so the simplest possible chassis was constructed and three war - surplus Liberty aero engines were squeezed into it . The vehicle was so simple it had no clutch or gearbox and only a single fixed ratio . Once started by a push start , it had to keep rolling . Driver comforts were minimal : the forward engine was sheathed in a crude attempt at streamlining , the two side - by - side behind were bare , with the driver perched between them and the one in front . - Coatesville is a city in Chester County, Pennsylvania, United States.
