Reacting more quickly to the Christmas Tree starting lights in order to win against a quicker opponent

A procedure in which the series ruling body confirms that a car (or other piece of equipment, they also approves things like helmets) meets those technical requirements they have issued. A car is thereafter deemed homologated and can be used in racing. There are modifications that do not need a new homologation, but in case of more extensive modifications, manufacturers create a new evolution of the car and homologate it.

A unit for measuring the amount of power an engine generates. NASCAR engines typically output 750 hp, while CART engines typically output 850 hp

When a cylinder fills with too much fuel, prohibiting compression and causing a mechanical malfunction (usually explosive)

The expected performance for vehicles in a given class, as assigned by NHRA. It allows various classes of cars in the same category to race against each other competitively

Officials' process to approve cars for racing, qualifying and practicing. Areas inspected include: weight, height, body profile and engine

Tracks measuring more than one mile in length, excluding superspeedways

Specific type of racing tires. A "halfway-house" between grooved slicks, which are used in dry weather, and full wet pattern tires. Intermediates are useful in damp to drying conditions where there are not significant amounts of standing water on the track surface

This pit crew member lifts the car off the ground by placing a floor jack under a specific spot on each side of the car for the tire changers

If driver leaves his starting position before the race has started he is deemed to have jumped the start and penalized

A differential fitted with a mechanism that limits the speed and torque differences between its two outputs. Limited slip ensures that some torque is always distributed to both wheels, even when one is on very slippery pavement.

These cars are not on the lead lap and are usually far slower than the leaders

Each part of the rally, separated by fixed minimum stopping time. In practice, each day of rally is different leg

The most ideal trajectory on straights and through corners for the fastest lap time. After rain, cars will sweep "the line" dry though the rest of the track remains damp

Used by some crews in notes to remind them to keep line in preparation to approaching corner

A pit crew member who holds a long-handled fluorescent board in front of a driver during a pit stop. The board is not withdrawn until refuelling and tire changes have been completed

A car is termed loose when a driver goes through a turn and the rear of the car starts to swing toward the outside wall, making the driver feel as if he's losing control of the car and about to spin. The rear tires aren't sticking well to the track and providing enough traction. This is also called oversteer.

Pieces of tire and debris that collect at the top or outside of a track during the race. If a driver runs over them, he will lose control of the car because it feels like it is on "marbles."

National Association for Stock Car Auto Racing, sanctioning and oversight body for NASCAR racing founded in 1948

Produced specifically as a fuel for drag racing, it is the result of a chemical reaction between nitric acid and propane

Set of codes that co-driver calls out to driver so that latter knows what is coming up ahead. Each crew has their own way of doing notes even though many are very similar. These codes normally consist some way of measuring distance (usually numbers like "5" for 50 meters) and another way to measure severity of the corner (like "K" for 90 degree turn). Notes also contain various extra words to caution, remind or control the driver (like "keep line" or "stone in")

These are strategic positions placed around a Grand Prix circuit where FIA observers watch for driving infringements, the actions of corner and safety crews and the recovery of stranded vehicles

Driver is accelerating ie. applying power

The race track has a single line where cars stick to the track and handle well. If the driver gets off-line the car could lose grip because there is not enough traction to keep the car stable outside of the groove. When tracks have more than one groove -- a high groove and a low groove -- cars can drive side-by-side around the track.

The situation that results when a car has more grip at the front than the rear. In mild form, this sort of chassis imbalance can result in dramatic "tail-out" slides. Extreme oversteer can result in the car going into a spin.

The area at the racetrack that includes the garages, inspection areas, hospitality areas, media center and drivers’ and officials’ motor homes

VIPs and Special Guest area only, usually with direct access to designated grandstand seating

Area where competitors are required to park cars for example during over-night halts

Designated with yellow or white lines, these are the specific areas for the race cars to use during pit stops

The crew allowed to go over pit wall and service a car. The maximum members allowed over the wall in NASCAR races is seven people and six people in CART races

Usually parallel to the track's frontstretch, a separate road where cars go when they need gas, tires, or repairs

Separated from the pit box by the pit wall, this is where teams watch the race and keep their equipment.

Routine breaks from the race, when the driver pulls into the pit and the crew services the car. Service includes refueling, tire changes, chassis adjustment and/or drinks for the driver

The cement wall that separates the pit box from the pit stalls

The driver who records the quickest qualifying lap is awarded the pole position -- the position on the inside of the first row. The second quickest driver is positioned on the outside of the front row - the outside pole

A driver is pre-staged when he or she is approximately seven inches behind the starting line and the small yellow light atop his/her side of the Christmas Tree is glowing

The one company that pays a majority of a team's sponsorship for a season and in return has its name and/or logo on the car in the most valuable areas. Corporate identification is also prominent on team and driver uniforms

All three large amber lights on the Christmas Tree flash simultaneously, followed four-tenths of a second later by the green starting light. A perfect reaction time on the Pro Tree is .400. This is used in races which feature heads-up competition, such as Top Fuel, Funny Car, Pro Stock, Pro Stock Bike, Alcohol Dragster, Alcohol Funny Car, Super Comp, Super Gas and Super Street

A tire gone flat

A special practice session that takes place between 1:00 and 2:00 p.m. on the Saturday preceding a Formula One race. Qualifying practice allows each driver a maximum 12 laps. His best time establishes his position on the race grid: the fastest drivers at the front and the slowest at the rear. Should a driver exceed 12 laps, all of his lap times are cancelled. The fastest driver starts from pole position

Cars in qualifying trim usually have the least downforce and drag possible, a light fuel load, a special set of tires and special engines. The cars are set up not for reliability but to reach maximum speed for a lap or two

The sheet metal immediately behind and in front of the tires of a stock car. Prime sponsor space because they are highly visible on TV. Open-wheel equivalent is the sidepod, where the primary sponsor’s name usually is displayed

Each Formula One car is required to carry the number published by the FIA at the start of each season. This number appears on the side and nose of the car and is at least 25 mm in height, so as to be clearly visible. Unlucky number 13 is excluded from the list
