Drag racing

Drag racing is a type of motor racing in which automobiles or motorcycles (usually specially prepared for the purpose) compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly ¼ mile (1,320 ft (402 m)), with a shorter 3/16 mile 10 feet (1,000 ft (305 m)) used by nitromethane powered Top Fuel dragsters and funny cars along with some bracket races, while 660 ft (201 m) (1/8 mi) is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.

Drag racing has existed in both street racing and regulated motorsport forms since automobiles and motorcycles were developed. The street racing form, which is usually illegal, is covered elsewhere; this article covers the legal sport.

Basics of drag racing

Before each race (commonly known as a pass), each driver is allowed to perform a burnout, which heats the driving tires and lays rubber down at the beginning of the track, improving traction. Each driver then lines up (or stages) at the starting line.
