Each car is equipped with a sensor unit which monitors and records data relevant to accidents and/or incidents

A driver is deep staged when, after staging, he or she rolls a few inches farther, causing the pre-stage light to go out. In that position, the driver is closer to the finish line, but dangerously close to a foul start.

Dialing under allows drivers in Super Stock and Stock, which are handicap categories, to select an elapsed time quicker than the national index. As with a dial-in, a driver selects a dial-under that he or she thinks the car will run, based on qualifying performance. The breakout rule is in effect.

The mechanism, usually found inside the gearbox casing, that drives and regulates both driveshafts, allowing them to rotate at different speeds.

 The turbulence created by the passing of a car. Another car following closely in this air finds its aerodynamics disrupted. With downforce cut drastically, the car behind has less effective steering, less grip and may spin off.

The size of an engine measured in cubic inches or centimeters

The air pressure flowing over the car creates a downward force that pushes a car onto the track, causing it to stick to the racing surface. It keeps cars from losing traction at high speeds, especially going through the turns.

Drivers race in single file and share air flow among them. The first car creates a vaccum that actually pulls the car behind it. Together the cars cut through the air much faster than they do separately.

Caused by air flowing around the car. Drag hinders a race car as it cuts through air. A streamlined car can accelerate faster with less drag because the car needs less horsepower.

An electronic system that involves the elimination of a direct mechanical link between the throttle pedal and engine. Throttle input is electronically fed to an on-board engine control unit (ECU) that then manages the behaviour of the engine accordingly. The system is also known as Fly-By-Wire

The spark plugs in a cylinder will not fire because the fuel mixture is too rich (i.e. too much fuel in the air-to-fuel mixture)
