Drifting is a driving technique where the driver intentionally oversteers, causing loss of traction in the rear wheels or all tires, while maintaining control from entry to exit of a corner. A car is drifting when the rear slip angle is greater than the front slip angle, to such an extent that often the front wheels are pointing in the opposite direction to the turn (e.g. car is turning left, wheels are pointed right or vice versa, also known as opposite lock or counter-steering).
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 and more importantly the turned wheels in a drift, speed is the speed entering a turn, the speed through a turn, and the speed exiting the turn; faster is better.
