The wheel-driven land speed record differs from the absolute land speed record in requiring that the vehicle be wheel-driven; thus, vehicles that use thrust from a jet engine or rocket are ineligible (although the use of such engines is permitted if they drive the wheels).

Until 1963, the absolute land speed record holder was always a wheel-driven car. The first jet-car to exceed the absolute record was Craig Breedlove's Spirit of America. Since then, no wheel-driven car has held the absolute record.[citation needed]

There is no "wheel-driven" category as such.[1] 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.[2]

Since 1963, holders of the wheel-driven land speed record have been:
