Glossary of Motorsport Terms

• Kerb-hopping - To clip, or drive over completely, the concrete kerbs (curbs) on the inside of a corner. While often the fastest method of negotiating chicanes in particular, the practice is usually frowned upon by race officials for the damage it can do to the kerbs, tyres and vehicles. The practice also can drag debris or water from behind the kerb onto the racing line.
• KERS - Kinetic Energy Recovery System. A device which recovers energy created when brakes are applied and stores it until required to add power in the engine. In 2008 KERS systems started to appear in the World Rally Championship and Formula One followed soon after, where its application is limited to a push to pass system.
• Kitty litter - Informal term with two possible meanings. It is either a nickname for a gravel trap, or for a material applied to the track surface to clean up a leaking fluid.
