A lifetime "membership" awarded by the SCTA or another sanctioning body / circuit to any driver who drives over a specified distance at a minimum speed of 200 mph, regardless of whether or not a speed record is broken. Membership can stretch over from the more exclusive 300 to the elite 400.

A
Air jacks
Four compressed air activated pistons mounted near the wheels of a racing car which project downwards to lifting the car off the ground during a pit stop for changing wheels and or giving mechanics access to the underside of the car for repairs.
Apex
The part of a corner where the racing line is nearest the inside of the bend.
Armchair enthusiast
Alternatively armchair racer, an individual who follow motorsport primarily on television and read books and magazines about the subject.
Awful Awful

B
B main
See Semi-feature.
B-team
A racing team that exists to develop the careers of upcoming drivers, such as Scuderia Toro Rosso and unofficially, Super Aguri F1.[1]
Back half
(drag racing) referring to distance from the 1/8th mile mark to the 1/4 mark of the track.
Backmarker
A slower car, usually in the process of being lapped by the leaders. It is sometimes a derogatory term.
Backup car
See Spare car.
Beam
(drag racing) starting line electric eye controlling prestaged and staged lights.
Banking
A.) The angle at which a track inclines towards the outside of a corner or from the lower to the higher side of a straight, also referred to as camber, more so when modest or negative, B.) a corner that inclines towards the outside or C.) an earth bank where spectators sit or stand
The Big One
A large pileup during a stock car race involving up to 30 cars. The term is largely reserved for restrictor plate racing at Daytona and Talladega.
Blend line
The painted line defining the exit from pit lane where it rejoins the race track. It prevents emerging race cars from driving into race traffic travelling past the pits. Competitors are penalised for crossing the blend line, ensuring cars have attained full racing speed before rejoining the race.
Blow
See Blown.
Blower
supercharger (occasionally turbocharger); in \'90s, generally grouped as "power adder" with turbocharger and nitrous.
Blown
A.) An engine that is supercharged (i.e. a "blown" V8 is a supercharged V8); or B.)An engine that has suffered serious failure, usually no longer running and/or having sustained irreparable damage (i.e. "Looks like #21 has a blown engine...his race is over").
Blowover
flipping of a car or boat, due to air under car lifting front wheels. Commonly suffered by dragsters and powerboats.
Bottle
(drag racing) refers to the nitrous system, also knock as the Jug.
Bottoming, Bottoming out
When the bottom of the chassis hits the track.[2]
Breakout

C
Camber
A.)The angle at which wheels are set up to tilt in or out, measured in degrees in or out from 90 degrees (i.e. "2.5 degrees negative camber" means each wheel is tilted 2.5 degrees inwards from vertical) "Positive camber" means the top of the tyre is angled outwards from the car; "negative camber" means that the top tilts inwards. Negative camber assists cornering performance as the outside tyres lean into the corner (like a motorcycle) which keeps the lateral forces on the tire lower and causes less flex in the sidewall, although it does also have the effect of increasing tyre wear. Or B.) Banking, the angle at which a corner inclines towards the outside or a straight from its lower side to its higher side. Sometimes specified as positive camber and negative camber, the latter indicating a decline from the inside of a corner.
Catch fence
A series of chain-link fencing used to slow out of control cars down. It is common on American short tracks and it was common on road course racing prior to the advent of gravel traps.
Caution / Caution period
See Full course yellow.
Chase vehicle
In off-road racing, a non-competitive vehicle that follows a competing vehicle to assist with repairs.[7]
Chicane
An artificial feature added to the natural course of a track to slow cars[8] or create a passing zone.

Responsible for all on-track activities including demonstrations and parades. The supervision of the track and all emergency services should at all times be under the ultimate control of the Clerk of the Course.
Closing/shutting the door
A driver takes an early defensive racing line into a corner to block the car behind from overtaking along the preferred line.
Co-driver
In rally racing, a co-driver directs the driver through the course by reading pacenotes which describe the turns and obstacles ahead. Also called a navigator. The term is also used in long-distance motor racing where more than one driver is sharing the same vehicle.
Competition caution
A preplanned full course yellow, mandated by the sanctioning body, where drivers bring their vehicles into the pits. Frequently done to change tires because of excessive tire wear.[9]
Continuously variable transmission (CVT)
A Formula One development created by WilliamsF1, it removed the gearbox entirely by creating cogs which could expand and contract as necessary to provide optimum drive during acceleration and or braking, instead of using a collection of cogs and shifting from one size to another to approximate optimum performance. The technology was banned from Formula One in the mid 1990s as it was very expensive. The technology has found application in road cars built by Honda and Nissan, amongst others.
Control
Where the series organisers specify that all competitors in the race must use an identical part; as in control tyre or control engine.
Crate motor
An engine that is ready-built and sealed by an independent company. Crate motors are sometimes mandated and sometimes optional. They are commonly used in regional touring series down to local tracks in divisions from late models on down. Crate motors are implemented to limit costs and it ensures that the entire field has the same equipment.[10]

D
Deep Braking
Applying the brakes later than normal when entering a turn.
Did Not Attend (often DNA)
Denotes a driver who was entered for a race but did attend the circuit. Sometimes referred to as Did Not Arrive or simply a "no show."
Density Altitude (often DA)
(drag racing) which referes often to the quality of air. Technically "quality of air" refers to the pressure drop as altitude above sea level increases. Atmospheric air pressure is lower at a race track higher above sea level. All non-turbocharged internal combustion engines produce less power as air pressure drops, as each intake stroke draws in less air per volume than normally. This may require the engine to be "tuned" to optimize the power, as it may still "think" it\'s at a lower altitude. Because a supercharged engine pressurizes intake air at a fixed mechanical ratio to the engines RPM\'s, it suffers a proportionate loss in power, but not as severe as a naturally-aspirated engine will. A turbocharged engine is largely unaffected, as the lower density of the intake air is offset by the lower backpressure resisting the exhaust flow through the turbo.
Dial-in
(drag racing) when bracket racing, drivers must estimate or "dial in" the time in which they expect to run. Therefore two unmatched cars in weight and power can compete, by a handicap system. If one runs a faster time than dialed in, it is a breakout.
Did Not Finish (often DNF)
A driver who did not finish the race. Some sanctioning bodies do not classify a driver in the final results if he did not finish completed a certain number of laps.
Did Not Qualify / Pre-qualify (often DNQ / DNPQ)
A failure to qualify or pre-qualify for a race.
Did Not Start (often DNS)
A driver did not attempt to compete in a race, even though he may have competed in practice sessions and / or qualifying. Not the same as the DNA already mentioned.
Digger
dragster (as distinct from a bodied car or flopper)[11].
Dirty air
The air disrupted by a car when it moves at speed, which can cause aerodynamic difficulties for a car following closely behind. The opposite of clean air.
Disqualify (often DQ or DSQ)
Where a competitor is removed from the results, usually in penalty for a technical infringement.
Doped (or Dope)
(drag racing) commonly used word in the southern states if the car is using nitrous or propane injection on diesels.
Door-slammer
Drag racing term used to group vehicles, usually sedan bodied, that still have functional doors for driver access to the vehicle, as opposed to Funny cars which have a single lightwight outer body draped over the racing chassis.
Downforce
Increased force holding the car onto the track. This is created by the aerodynamics or aerodynamic aids (F1 wings, etc.)of a vehicle which causes a "reverse lift" effect. That is, creating an area of low pressure (suction) under the car and/or under the wing(s) or other aids fixed to the car, the higher pressure above forcing the tires harder to the ground, effectively increasing the static friction. This allows it to travel faster through a corner, at the cost of having a reduced overall top speed, since drag is proportionate to lift and downforce is caused by lift.
Drafting
A technique where multiple vehicles align in a close group reducing the overall effect of drag due to exploiting the lead object\'s slipstream. Same as slipstreaming.
Drifting
Driftng is a form of motorsport in which drivers intentionally provoke constant oversteering slides while preserving vehicle control and a high exit speed. In motor racing, drifting is a cornering technique (also called a four-wheel drift) where a car takes a high-speed corner held at an angle on the track without major steering inputs, balancing natural understeer with power oversteer.
Drive-through penalty
A penalty applied by race officials while the race is underway. A competitor is directed to drive into the pit lane and travel its length at much reduced speed (pit lanes are mostly speed-limited to protect the pitcrew and marshals) losing significant track position in the process. When the driver is serving his drive through penalty he is not allowed to stop anywhere in the pits.[2] See also Stop-go penalty.
Driver development program
A program used by racing teams to develop younger drivers.
Drivers\' meeting
A meeting where drivers and officials meet before a race to discuss the upcoming event. Also referred to as Drivers\' briefing or Driver and Crew Chief meeting, as in some series, the driver and his crew chief must attend.

E
E.T.
Acronym for Elapsed Time. A term used in drag racing about the total time the run took, from start, to finish.
E.T. Slip
In drag racing, it is a slip of paper turned into the race promoter, which denotes elapsed time for both drivers, and who won the race. This is an official document, used for timekeeping.
Excluded
Removed from competition before the race has started, generally due to an infringement during practice or qualifying.

F
Factory-backed
A racing team/driver that competes with official sanction and financial support from a manufacturer.
Fan Car
Usually refers specifically to the Brabham BT46 Formula One car, although the concept was actually pioneered by sports car manufacturer Chaparral Cars on the Chaparral 2J. The placement of a large fan at the rear of the chassis driven either independently or by the engine with the purpose of creating negative air-pressure underneath the car to create additional downforce for increased cornering speed.
Fastest Lap
The fastest time in which a lap was completed by a driver during a race. Sometimes rewarded with bonus championship points.
Field
The competing cars in an event.
First or Worse
In drag racing, if both drivers commit a foul, the driver who commits the foul first loses, unless it is two separate fouls, where the loser is the driver who committed the worse foul (lane violation is worse than foul start, and failure to participate in a post-run inspection is worst).
Flag-to-flag coverage
Television or radio coverage that consists of the entire race start-to-finish rather than highlights, tape delayed, "packaged" coverage, or highlights of the first portion of the race before broadcasting the final quarter of the race live. Derives from green flag (start) to checkered flag (finish). Instituted largely in the late 1970s, with the 1979 Daytona 500 being the first major 500-mile race with live, flag-to-flag coverage.
Flat spot
When a wheel locks under braking, the car skids and leaves a flat spot on the section of the tyre that was touching the ground at the time.[2]
Flopper
(drag racing) Funny Car, short for "fender flopper." Coined by dragster crews in the late 1960s to separate Funny Cars, which had fiberglass bodies with fenders, from dragsters. Erroneously attributed to flip-top bodies of Funny Cars.
Flying lap
A lap started by a competitor at optimum speed, as opposed to a lap from a standing start, usually in qualifying.

Gravel trap
Off-track run-off area, usually positioned on the outside of corners, filled with gravel intended to slow down and stop cars that have left the track at speed. Generally there are tyre barriers between a gravel trap and the catch fencing, in order to protect the spectators.[2] Sometimes nicknamed "kitty litter" for its visual resemblance.
Green-white-checker finish
When a full-course caution comes out right before the end of a race, the race is extended beyond its scheduled distance. Depending on sanctioning body, there may be either one or multiple attempts at a restart, between one and five laps, before the race is declared officially over. NASCAR\'s national series will have a maximum of three attempts if the penultimate lap only under caution, while some short track races have unlimited attempts at a span between one and five consecutive green-flag laps. In British Superbike Championship motorcycle racing, if a caution is called in the final third of the race, three additional laps will be added on the ensuing restart in a green-white-checker style finish.[12]
Grenade
wreck an engine (the engine "grenaded") due to internal failure. Distinct from "popping a blower". A hand-grenade engine is a usually derogatory engine of tuned to maximise engine power at the cost of low mechanical relaibility.
Grid
The starting formation of a race, generally in rows of two for cars and four for bikes.
Groove
Also called The Groove. A term used in drag racing about the center portion of the lane, where the cars can gain traction quicker, and run faster times.
Ground effect
A method of creating downforce by the shape of the car\'s body, notably by shaping the underside of the car in combination with the car\'s lateral edges in order the trap and dramatically slow the airflow running underneath the car, effectively turning the entire car into a wing.
Gurney, Gurney flap
A small lip placed at the trailing edge of a race car\'s aerodynamic wing. Despite its relative size, often only millimetres tall, it can double the downforce achieved by the wing, although at the premium of increasing drag, hence the small size. Named for the man commonly attributed to its proliferation, Formula One driver and constructor, Dan Gurney. Also known as a wickerbill.

H

Hairpin
A tight 180 degree corner that twists back on itself.
Heads-up Racing
where both drivers leave at the same time and is used in all professional ("pro") classes.

Holeshot
(dirt road course motorcycle racing), the rider who is the first one through the first turn at the start of a race
(drag racing) getting a substantial starting line advantage due to a quicker reaction time. The other driver gets "holeshotted" "welded to the line" or "left at the tree." A "holeshot win" is any win in a heads-up class where a slower car beats a faster car because of better reaction time, despite having a slower elapsed time (e.t.).

Invert
The portion of the field which is started by reverse qualifying speed. With an invert of five, the fifth-fastest qualifier starts first and the fastest qualifier starts fifth. The rest of the field starts by their qualifying speed (sixth fastest starts sixth). The invert is often not announced before qualifying or a dice/die roll happens after qualifying.[13]

J
James Bond / James Bond Red
In drag racing, a driver\'s reaction time (when he leaves the start line) is seven thousands of a second after the green light (.007). A "James Bond Red" is a reaction time of -.007 seconds (red light), which is disqualification unless the opponent commits a more serious violation.
Jump start
In a standing start, when a vehicle moves from its grid slot before the start of a race is signaled. In a rolling start, when a car passes before they cross the start-finish line or the restart line. When this is done, a penalty is usually imposed.[2]

K
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.

L
Ladder series
Generally refers to a category or series of lesser importance which in most cases will race at the same race meeting as a senior category. Cars will be generally similar in characteristic to drive but will be smaller, less powerful and/or slower.

Pop-off valve
Device attached to turbochargers used to limit the additional horsepower they produce. Usually a mechanical device, activated when the pressure within the turbocharger reaches a certain point, opening a valve (popping off), thus reducing boost pressure. Used primarily for safety (speed reduction of the racing cars) or cost (reducing stress on both turbo and engine, lengthening the life of the parts prior to failure or rebuild).
Pre-qualifying

Riding mechanic
an early term for a co-driver.
Ripple strip
Concrete kerb, usually placed on the inside of a corner, painted in chunks of colour, usually red and white alternately, hence the \'ripple\'.

Rolling start
A starting method where moving cars start a race after the starter displays a green flag.
Rumble strip
Variation of ripple strip with an upward-pointed, rounded saw-tooth edge. The saw-tooth effect is to discourage competitors from kerb-hopping. The saw-tooth creates a rumble sound and feel for the competitor when driven over.
Run-off area
Areas off the track put aside for vehicles to leave the track in case of emergency without accident.

S
Safety car
A safety car or pace car limits the speed of competing cars on a racetrack in the case of an accident or caution periods caused by obstruction/s on the track.
Sandbag
To gain a competitive advantage by deliberately underperforming at an event.
Sandtrap
An area at the very end of a dragstrip to keep vehicles from going off the track, it is filled with, as the name implies, sand. The design of the sandtrap is intentional, and used as a safety device.
Satellite team
A second racing team operated by a primary team but maintaining a separate identity.
Scattershield
(drag racing) metal sheet protecting driver in case of transmission failure[18].
Scrutineer
A qualified official who examines racing vehicles pre-race for compliance with the rules of competition, usually in a scrutineering bay adjacent to the pit lane.
Sector
A section of one complete lap of the circuit used for timing purposes. For the purposes of Formula One, each circuit is split into three sectors.
Semi-automatic gearbox
A motorsport application, created initially by Scuderia Ferrari for Formula One, in which the driver can change gears manually, but without having to manually activate the clutch. On open wheel race cars it is usually activated by paddles immediately behind the steering wheel, although touring cars and rally usually place the gear shifter as a gear stick in the more conventional position on the centre console, but occasionally is mounted as a stalk off the steering column, when activated, automatically engages the clutch and changes the gear and releases the clutch without any further input from the driver.
Semi feature, B-main, Qualifier
A qualifying race before the main event, where non-qualified cars compete for a predetermined number of spots in the main event. Some races have a C-main where the top finisher(s) qualify for the B-main. At those events, the main event is known as the "A-main".
Setup
The set of adjustments made to the vehicle in order to optimize its behavior.
Shootout
See Superpole.
Short shifting
A technique used, primarily in motorsport, to regain control of a car through a high speed corner. Involves the driver shifting up a gear earlier than usual.
Shunt
A crash.
Shutdown Area
In drag racing, it is the extra 440 yards from the finish line, to the sand trap, used to safely shut down the car, and turn it off the track, so the next racers can begin their race.
Skid plate
Metal plates, most commonly titanium, fixed to the bottom of flat bottomed racing cars on the undertray facing the racing surface, put there to protect the undertray from ground strikes tearing through the undertray. Today less common as racing cars usually are mandated to have a ground clearance that is less critical to hitting the track.
Slapper bar
see traction bar.
Slick
A tyre with no tread pattern, maximising the amount of tyre rubber in contact with the racing surface. A specialist motor racing application as in wet weather conditions these tyres have little resistance to aquaplaning.
Slingshot
front-engined dragster, named for the driving position behind the rear wheels (erroneously attributed to launch speed).
Slingshot pass
A pass using Slipstreaming (see below).
Slipstreaming
A car following close behind another uses the slipstream created by the lead car to close the gap between them or pass it. Same as drafting.
Smoking the tires
Also called Lighting the hides, or Blowing the tires off. A term used mostly in drag racing when a loss of traction occurs, causing the rear tires to rise, and smoke profusely. This usually happens off the starting line. When this happens during a race, it usually results in a loss, unless the opponent also loses traction as well.
Spare car, Backup car
A car used by a driver if he has damaged his main car. It may or may not have the same setup as the primary car. Teams in most major racing series have a spare car available at the track. At Indianapolis, it is traditionally called a "T Car" ("T" loosely short for "test" or "temporary")
Spec
see One-make racing
Special stage
A section of road or track, closed off used for timed runs in rallying. A rally is made up of a number of special stages.
Splash and dash, Splash and go
A pit stop which involves refueling the car only, often less than a full tank.
Splitter
Also referred to as the front Spoiler or Front Air Dam. Aerodynamic device placed on the nose of some touring cars and GTs to improve airflow around the nose of the car and sometimes create downforce for the front wheels to aid steering. It is prominent on NASCAR\'s Car of Tomorrow body style.
Spoiler
Aerodynamic device attached to the trailing edge of a race car to increase its rear downforce. The difference between a spoiler and a wing is that wings are generally multi-element with air passing both above and below the aerodynamic surface, whereas a spoiler is flush fitted to the car\'s bodywork.
Spotter
a person, positioned high above the circuit, who communicates what going on the track to the driver
Standard tree
(drag racing) timing lights which flash in sequence five tenths of a second between each yellow light before turning green. Traditional form, before introduction of pro tree.
Standing start
A starting method where the race machines are stationary on the grid.
Start and park
A team or driver who starts a race and only runs a small number of laps to avoid using up resources (tires, parts).
Steward
The adjudicator or referee at a race meeting who interprets incidents and decides whether penalties or fines should be issued.
Stint
The period a driver is at the wheel in an event involving more than one driver in the vehicle. Sometimes refers to the period of driving between pit stops.
Stop-go penalty
Requires erring drivers to enter their pit and come to a complete stop before resuming, sometimes for a specified time. Sometimes called a Stop and go penalty, it penalises drivers more than a Drive-through penalty.
Stripe or Strip
The start/finish line.
Struck the tires
(drag racing) loss of traction, causing them to smoke.
Success ballast
A method used to level performance between competitors by adding weight to cars the win races or are successful. Somestimes referred to as Lead trophy as the usage of lead bars is most popular in applying the additional weight.
Superpole, or Shootout
A selection procedure in which the ten or 15 fastest qualifiers compete for grid positions in a single-lap effort without other vehicles on the track. While not specifically referenced, most NASCAR races will use this style of qualifying for all cars.
Support race
A race(s) that takes place before and after the title race, also during qualifying day.
Super Special
Timed special stage in a rally on a purpose-built track, often in a stadium. Usually two cars will set off at the same time in separate lanes, and at the halfway point of the stage they will swap lanes, usually due to a crossover involving a bridge. A similar format is used in the Race of Champions.
Swinger
(from Sidecar racing) A passenger on a racing motorcycle sidecar who athletically moves from one side of the sidecar to the other, altering a sidecar\'s weight distribution to assist in cornering speed and in some corners to prevent the sidecar from tipping over.

T
T-bone
A collision in which the front of a car crashes into the side of another car, forming a "T" shape
Tank-slapper
When the front wheel of a motorcycle oscillates rapidly, causing the handlebars to slap against the fuel tank.[19] It is increasingly being used to describe a vehicle which loses traction at the rear, regains traction and loses it again, causing the rear to weave side to side independently of the front of the car. This is more often referred to as Fish-tailing.
Team orders
The practice of driver allowing another from the same team or manufacturer to gain a higher finish at the direction of the team management.It has been forbidden in Formula One since the 2003 season, as a consequence of the 2002 Austrian Grand Prix controversy.
Ten-tenths
Refers to driving a car to its absolute potential.
Throttleman
In offshore powerboat racing, the boat\'s second occupant who work alongside the driver, whose role is to steer the boat. The throttleman\'s position is to get as much speed out of the boat by controlling the hand-throttle during a race whilst it hops over tides after tides and preventing the propeller from spinning wildly whilst the boat is airborne, which causes the engine to overrev, leading to engine damage.
Throw a belt
(drag racing) losing the drive belt connecting the engine\'s crankshaft to the supercharger.
Tight
See Understeer.
Tin-top
Road car-derived vehicles with a roof, mainly in touring car racing.
Tire shake
A term in drag racing, when the engine is putting out more horespower than the drive axle can handle, causing the rear tires to shake violently. This results in a loss of speed, and can also result in loss of steering, and occasionally, lead to on track accidents. Refer to in other disciplines sometimes as Axle Tramp.
Top end
(drag racing) finish line of strip; high part of engine\'s rev band.
Track
The racing surface.
Traction bars
(drag racing) rear struts fixed to rear axle to keep rear axle from twisting, causing wheel hop and loss of traction; also called slapper bars. In FWD cars, commonly import drag racing, used to keep front wheels in the ground.
Traction control
This regulates the power supplied to the wheels of a vehicle to prevent wheelspin. It is banned in many forms of motor racing.
Trap(s)
(drag racing) the 20 meter (66 ft) timing lights at top end of race track to measure speed & E.T.
Trap Speed
(drag racing) Speed as measured by the speed trap near the finish line, indicative of the maximum speed reached in a run.

U
Understeer or push
Cornering behaviour where the front wheels do not follow the steered course but instead push out toward the outside of the turn. Known as push in NASCAR and other stock car racing. Opposite of oversteer.
Undertray
Flat or stepped flat surface on the bottom of open wheel and sports prototype racing cars. Theory has varied along with aerodynamic developments and regulations, from the sidepod tunnels of ground effect to the flat undertrays of the 1980s in various attempts to use aerodynamics to suck the cars closer to the bitumen, minimising the air underneath the car that could slow its progress. Today most such categories feature a stepped undertray with sidepods siting higher in the air than the centre of the car, usually mandated by series organisers in an attempt to limit vehicle performance. Also refers to flat surfaces extending behind splitters in sedan and GT based racing cars.

V
Victory lane
The place where the winner of a race goes to celebrate victory after winning an event.[20]
Victory lap
A lap, after the conclusion of the race, where the winning racer drives at reduced speed to celebrate his or her victory.

W
Weight shifting
A technique used to reduce understeer. This involves the driver decelerating through a corner to shift the weight of the car from the back to the front, increasing grip of the front tyres and decreasing understeer.
Wet (or wet-weather) tyre
A racing tyre with deep grooves designed to displace standing water, allowing the tyre to obtain grip in conditions where dry weather tyres (slicks) would aquaplane. Monsoon wet has become a term used for extremely wet conditions.
Wheel banging
When the wheels of two different race cars slightly collide during an overtaking manoeuvre.[21]
Wheel hop
(drag racing) violent shaking of the car as the tires lose and regain traction in quick succession.
Wheelie
In a rear wheel drive vehicle, when the front wheel(s) rise up in the air under acceleration.
Wheelie bars
(drag racing) rear struts fixed to rear axle, which protrude out to rear of car to help prevent car\'s front from raising too high or flipping over on launch.
Wheelspin
When the rear tyres (or front tyres in the case of a front wheel drive vehicle) break traction with the racing surface under acceleration, spinning the wheels faster than they move across the surface. On higher traction surfaces like bitumen the tyre will begin to shred and melt from the friction, producing white smoke.
Wheelstand
wheelie. In drag racing, an extreme case, with front wheels very near vertical
Wheelstander
In drag racing, an exhibition car designed to complete a pass in a wheelstand (wheels near vertical)
Wickerbill
See Gurney flap.
Wing
Aerodynamic device on many racing cars. The principle is the same as an aircraft wing except in motor racing applications the wing is inverted to create downforce instead of lift, pressing the car onto the road surface to increase traction.
Wired to the tree
A drag racing term used to describe a racer that consistently beats his opponent off the starting line. Also called Chopping down the Christmas Tree.
Wishbone
Suspension control arm with three points, shaped roughly like a chicken wishbone.
Works team
A motor racing team supported by a vehicle manufacturer, usually run in-house at the manufacturer\'s premises. A works driver is a driver who drives for the works team.

Y
Yellow chequer
A term derived when the final lap(s) in a race is completed during a full course yellow while the field is under the control of the Safety Car. In this instance the yellow and chequered flags are waved together and the race is declared finished with the order the same as when the full course yellow began. Unpopular with spectators because of the anti-climactic nature of the finish, the possibility does make some senior race official hesitate to use it late in the race, or direct to slow the safety car in order that the hazard may be cleared in time for a competitive race finish. The Indy Racing League has a Yellow chequer rule, and NASCAR allows it (1) if a race is shortened because of curfew or darkness, (2) if the race is areadly on its final lap when the yellow must be waved, or (3) if there is a yellow implemented during the third attempt at the green-white-checkered finish once the leader has taken the green flag. In Formula One, when there is a yellow chequer, the safety car will not lead the leader to the finish line, unlike the IRL and NASCAR.

Z
Zero car
Used in rallying. Prior to the rally cars running over a special stage several official vehicles run through the course to check for safety, conditions of the road, to see if spectators or animals may be a hazard or for obstructions. Sometimes there are a triple zero (000) and double zero (00) as well as the zero. Zero cars travel the course immediately ahead of the competitors and are usually rally cars themselves.
Zero Light
Also known as "cutting a zero," and a "zero R.T." Used in drag racing when someone leaves the starting line at the exact moment when the light turns green (.000). Very difficult to achieve, due to the quick flashing of the lights on a Pro tree.
