A rocket dragster is a rocket car used for competing in drag racing, and this type holds the unofficial world record for the 1/4 mile. 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.

High Quality Content by WIKIPEDIA articles! A rocket car is a land rocket vehicle powered by a rocket engine. A rocket dragster is a rocket car used for competing in drag racing, and this type holds the unofficial world record for the 1/4 mile. 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 relatively short 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 very high and high speeds are fairly easily achieved. Kitty O'Neil in 1977 recorded the quickest quarter mile elapsed time of 3.22 seconds at 396 mph using hydrogen peroxide powered engines and made a quarter mile run with a top speed of 412 mph. This is in excess of the performance of more familiar piston engined dragsters.
