Drag racing

Drag racing is a type of motor racing in which automobiles or motorcycles 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 1⁄4 mi, with a shorter, 1,000 ft distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The 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.
