A rocket car is a land vehicle powered by a rocket engine. Rocket cars are capable of very high speeds, and at one time held the land speed record (now held by a jet car). Rocket cars differ from jet powered cars in that they carry both fuel and oxidizer on board, eliminating the need for an air inlet and compressor which add weight and increase drag. Rocket cars run their engines for very brief periods of time, usually less than 20 seconds, but the acceleration levels that rocket cars can reach due to their high thrust-to-weight ratio are such that supersonic speeds can be reached. Rocket cars have been used as rocket dragsters, and hold the unofficial world record for the 1/4 mile. [edit] History
