Drifting refers to a driving technique and to a
motorsport where the driver intentionally over steers, causing loss
of traction in the rear wheels through turns, while maintaining
vehicle control and a high exit speed. As a motor sport,
professional drifting competitions are held worldwide. Drift racing
challenges drivers to navigate a course in a sustained sideslip by
exploiting coupled nonlinearities in the tire force response.
Drifting competitions are judged
based on line, angle, speed, and show factor. Line involves taking
the correct line, which is usually announced beforehand by judges.
The show factor is based on multiple things, such as the amount of
smoke, how close the car is to the wall or designated clipping
point, and the crowd's reaction. Angle is the angle of a car in a
drift, speed is the speed entering a turn, the speed through a
turn, and the speed exiting the turn; faster is better.
