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.[citation needed] 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.
Bleach box
(drag racing) Area where bleach is deposited for cars to perform burnouts (q.v).[citation needed] Gasoline (since discontinued for safety reasons), water, and TrackBite are also used.
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.[citation needed] Commonly suffered by dragsters and powerboats.
Bottle
(drag racing) refers to the nitrous system,[citation needed] also the jug.
Bottoming, Bottoming out

performed to heat the tires up for better traction.[citation needed]
Buschwhacker or Claim Jumper
(NASCAR) A term for drivers who regularly race in the first tier NASCAR series, the Sprint Cup Series, who make guest or semi-regular appearances racing in the second-tier NASCAR Nationwide Series. The term was named originally for then sponsor of the second-tier series Anheuser-Busch brewery. The newer term references insurance abuse (from the current sponsor).
Bye
Allows a driver to advance to the next stage or heat of an event, without competing, when there are uneven numbers entered. Commonly used in speedway, drag racing and drifting etc.

C

Catch fence at an American dirt track
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.[12]
Chicane

The "Christmas tree counting down at SIR
Chopping Down the Christmas Tree
See Wired to the tree.
Christmas tree (or tree)
The series of lights (in drag racing) that signal the approach and start of a race in addition to showing starting violations.
Clean air
Air that has not been affected by turbulence from other cars.[7] The opposite of dirty air.
Clerk of Course
Responsible for all on-track activities including demonstrations and parades.[citation needed] 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.[citation needed]
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 historically when the reading of maps played a larger part in rallies prior to the widespread adoption of pacenoting. The term is also used in long-distance sports car and touring car 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.[14]
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;[citation needed] 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.[15]
Customer car
When a racing team uses a car built for them, either by another team, or by a specialist racing chassis manufacturer. Primarily a Formula One term where the majority of teams build their own cars, and practice that is now banned from F1.[citation needed]

D

A drift competition in progress
Deep braking
Applying the brakes later than normal when entering a turn.

Delta Time (also Pit-Stop Delta)

The entire time it generally takes a driver to enter the pit lane, make a full pit stop, and exit the pit area back to the track to resume racing at optimum pace. For example, a Delta Time of 25 seconds means the entire pitting process (entering, stopping and exiting) cost the driver 25 seconds not driving at full race speed even though the car may have been stationary in the pit box for only 5 seconds.

Density Altitude (often DA)

(drag racing) which often refers 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 Attend (often DNA)

Denotes a driver who was entered for a race but did not attend the circuit. Sometimes referred to as Did Not Arrive or simply a "no show."

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 / Did Not 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).[16]
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. Sometimes, but not always, interchangeable with Excluded.
Dogleg
A gentle turn or kink on a racing circuit, usually associated with road courses, but also present on oval tracks. On road courses, a dogleg may be present on a long straightaway (e.g. Mid-Ohio), curving the straight slightly, but usually not enough to require drivers to slow down much for the turn. On an oval, a dogleg can be located on the frontstrech (e.g. Charlotte) or backstrech (e.g. Phoenix) creating an oblong shape, adding a challenge, increasing sightlines for fans, and again, usually not requiring drivers to slow down for the extra curve. A quad-oval is also referred to as a "double dogleg."
Doped (or Dope)
(drag racing) commonly used word in the southern states[citation needed] 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,[citation needed] 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.[7] See also Stop-go penalty.
Drivers' meeting before a motocross race
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.
Dry line
On a drying circuit, the racing line that becomes dry first as the cars displace water from it.

E

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. In Europe, known as a works team.
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
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;[citation needed] (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.[7]
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,[citation needed] as opposed to a lap from a standing start, usually in qualifying.
Formation lap
The lap cars make before forming up on the grid for the start.[7]
Formula racing

Fuel
(drag racing) mix of methanol and nitromethane ("pop," nitro); race class using it.
Fueler
(drag racing) any car running fuel or in Fuel class (most often, TFD or TF/FC).
Full course yellow
When yellow flags are deployed at every flag point around a race circuit and a Safety Car leads the field until a hazard is cleared.
Funny Car
(drag racing) a vehicle with a single-piece body draped over the chassis which is lifted off or rear-hinged to allow the driver access to the cabin; a race class for such a car

G

Graining
When small grains of rubber start coming off a tyre.[7] See also marbles.
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.[7] Sometimes nicknamed "kitty litter" for its visual resemblance.
Grand marshal
Ceremonial marshaling role at a race meeting. Largely held by celebrities or retired notable drivers with no actual duties or responsibilities beyond the waving of a flag to commence activity or to announce the traditional start your engines prior to some races.
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.[17]
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 reliability.
Grid
The starting formation of a race,[citation needed] 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 turn on the Mont Ventoux in France
Hairpin
A tight 180 degree corner that twists back on itself.
Handicap
where cars start a race in the reverse order of qualifying, or perceived race pace, usually with timed gaps between cars starting a race. More common in racing's early days than today,[citation needed] the effect was the produce a race result in which all cars would arrive at the race finish together, regardless of the performance of the race vehicle.
Hang-out-to-dry
where, upon having gained track position after overtaking a rival car, the lead driver simply blocks, and slows their rival down slightly.[citation needed]
Heads-up Racing
where both drivers leave at the same time and is used in all professional ("pro") classes.
Heat
A shorter race which decides the participants of the main race and sometimes starting order as well, usually there are more heats in which only a part of the drivers from the entry list take part. Can also mean part of the main race, when it consists of two or more parts.
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.).
Homologation
Process by which a new vehicle or part of a vehicle is approved by organisers for usage in racing.
Hook up
(drag racing) Good traction between tires and track resulting in increased acceleration and reduced slipping or smoking of tires.

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.[18]

J

Jet dryer mounted on a pickup truck
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.
Jet dryer
An airplane engine mounted on a pickup truck or trailer. The exhaust from the engine is used to blow debris or evaporate moisture from the racing surface.[19]
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. In drag racing, a jump start is signalled by a red light in the offending driver's lane, and he loses unless a more serious foul (boundary line or failure to report to post-race inspection after a round win) occurs.[7]

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.
Kit
(drag racing) refers to a turbo kit or a nitrous kit.[citation needed] Using nitrous oxide in the professional categories in drag racing is illegal.
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.[citation needed]

L

                     Early apex                      Ideal Line                      Late apex
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. Competitors will generally be younger emerging drivers who are climbing an apprenticeship 'ladder' towards entry into the senior series.
Lambda reading
Fuel to air ratio readings, used to determine how much fuel is pushed through the fuel injectors into the cylinders for combustion.
Lap of honour
A non-competitive lap taken before or after the race by a driver in celebration.[citation needed] Also known as a lap of honor, or, if after the race, a victory lap.
Lap record
Fastest race lap recorded at a circuit for a category of race car. The circumstances allowed vary significantly, but practice laps are generally not considered official records. Laps recorded in qualifying may or may not contribute but are sometimes referred together with practice laps as Qualifying lap record. The outright lap record is the fastest race lap ever recorded at any particular circuit, regardless of category of vehicle being raced.
Lead trophy
See Success ballast.
Lid
Used to describe the top of something, either a crash helmet or the roof of a car.[citation needed]
Lit the tires
(drag racing) lost traction, producing smoke.[citation needed]

Marshal
A person responsible for signaling track conditions to drivers (through use of flags), extinguishing fires, removing damaged cars from the track and sometimes providing emergency first aid.
Meatball
A specific racing flag used in some countries to indicate to a competitor there is a defect with the car which has the potential to cause a safety risk to the competitor or to another competitor.[citation needed] Most usually applied to trailing smoke or loose bodywork. The flag is black with a large orange dot in the centre of the flag, looking vaguely like a meatball.
Meth
(drag racing) refers to methanol injection used in conjunction with racing gasoline[citation needed]
Missing man formation
The vehicle on the pole position drops back a row during a pace lap to salute a deceased motorsport personality.[20]
Mobile chicane

Monsoon wet
Increasingly common nickname[citation needed] for an extreme weather version of the wet weather tyre.
Motorsport Valley
A tag given to the mid-south of England by the Motorsport Industry Association where high concentration of activities within the motorsport industry on and off track occur.
Mountain motor
(mainly North American) term for large-displacement engines, often used in hot rods and drag racers. Named for their size (over 8,100 cubic centimetres, or 500 cubic inches, the limit in some sanctioning bodies), and for being constructed in the mountains of Tennessee and North Carolina.[22]

Out-brake
Gaining time or position by braking harder and deeper in a corner.[23]
Out-lap
The first lap to be completed after exiting the pit lane, either during a race or during practice or qualifying. Also known as a reconnaissance lap if it is not taken at race speed, e.g. when a car leaves the pit lane to take up its position on the grid prior to the race start.
Outright lap record
Fastest lap recorded at a circuit of any category of race car. Most often this does not include qualifying and practice laps but confusingly some sources[specify] occasionally include laps not recorded during races.
Overdrive
(drag racing) The ratio between the revolutions of the supercharger to the revolutions of the engine, controlling amount of boost; see underdrive.

While the practice has been superseded by modern electronic timing systems, the expression remains in regular use by commentators and others.
Pit board
A board that is held up from the pit wall to the side of the finishing straight when a driver goes past, to confirm their position in the race and the amount of laps remaining.[21] Before the introduction of radio communication, also used to instruct drivers to pit for fuel and/or tires, or to comply with rules violations.

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

Sled
In truck and tractor pulling, an implement pulled behind the machine which uses friction to stop the machine.[25]
Slick (clay oval)
A phenomenon caused on short-circuit clay ovals that dry out too much.[citation needed] Clay circuits that do not maintain a certain amount of moisture as a race meeting progresses will start to wear the rubber off the soft specialised clay surface tyres of clay surface race car tyres much in the same way asphalt or concrete paved circuits do, giving the track surface a noticeably black shade.
Formula One slick
Slick (tyre)
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.
Slidejob pass
Especially in dirt oval racing, a passing car dives low into a corner, deliberately oversteers in front of the vehicle being passed in an attempt to slow their momentum. The vehicle being passed often attempts to pass back by steering low coming out of the corner down the following straightaway.
Slingshot
front-engined dragster, named for the driving position behind the rear wheels (erroneously attributed to launch speed).[citation needed]
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")[citation needed]

Currently, in World Rally Championship, a driver will be given the time of the fastest driver of their class, plus a five-minute-penalty for each missed stage.[citation needed]
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.

T

T-bone
T-bone
A collision in which the front of a car crashes into the side of another car, forming a "T" shape. This is one of the more dangerous types of crash due to the relative vulnerability of side impacts where there is much less deformable structure on the side of a car to protect the driver. Also, to crash into another car in such a fashion; the victim is "T-boned".
T-car
Alternative term for spare/backup car[26]
Tank-slapper
When the front wheel of a motorcycle oscillates rapidly, causing the handlebars to slap against the fuel tank.[27] 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.
Tansō (単走 solo run?)
(drifting) Japanese term for individual passes where drivers drive whilst being observed in front of judges in an attempt to vy for the top spot.

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 adjust the trim tab whilst observing water conditions and extract as much speed out of the boat by controlling the hand-throttle during a race whilst it hops over tides after tides to prevent the propellers from spinning wildly whilst the boat is airborne, which causes the engine to overrev, leading to engine damage.[28]

Top end
(drag racing) finish line of strip; high part of engine's rev band.
Track
The racing surface.

Undertray
Flat or stepped flat surface on the bottom of open wheel and sports prototype racing cars.[citation needed] 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.[29]
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

Wallies
A slower car, usually found at the rear of the grid.[citation needed] It is sometimes a derogatory term.
Wear the shiny off
A term used, mostly within drag racing, when a brand new car either hits the wall, or, in the Pro Stock class, when a new car flips over into its top and continues down the track for a considerable length, peeling the paint off.
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.[30]
Wheel hop
(drag racing) violent shaking of the car as the tires lose and regain traction in quick succession.
Maynard Yingst performing a wheelie in his sprint car

The wheelie bar (foreground) and parachute (gray) on Kenny Bernstein's Top Fuel dragster.
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.[citation needed]
Wheelstander
In drag racing, an exhibition car designed to complete a pass in a wheelstand (wheels near vertical)
Wickerbill
See Gurney flap.

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.[citation needed] 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 already 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.[citation needed] 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.[citation needed] 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.
