A dragster is a specialized competition automobile used in drag racing. Dragsters, also commonly called "diggers", can be broadly placed in three categories, based on the fuel they use: gasoline, methanol, and nitromethane. They are most commonly single-engined, though twin-engined and quad-engined designs did race in the 1950s and 1960s.
The 25-foot-long Top Fuel dragster can cover the quarter-mile in 4.4 seconds at up to 540 kmph, mostly using a 4130 chrome molly chassis constructed in the USA.
