Nascar Glossary of Terms |
| |
|
| |
|
| |
Nextel Cup racing, as does any
other professional sport, has a language all its own. The meaning and usage
of the terms specific to the sport pop up through any explanation of its
racing action. The following is a comprehensive list of 200 terms you might
hear around a Nextel Cup garage, or during a race: |
| |
|
| P |
|
A-PILLAR |
| |
The two furthest forward pillars
(one on each side of the car) that extends from the roof of a car to base of
the windshield. |
| |
|
| P |
|
AERO PUSH |
| |
When following another vehicle
closely, the airflow off the lead vehicle does not travel across the
following one(s) in a normal manner. Therefore, downforce on the front of the
trailing vehicle(s) is decreased and it does not turn in the corners as well,
resulting in an "aero push." This condition is more apparent on the
exit of the turns. |
| |
|
| P |
|
AERO WARS |
| |
In
late 1969, after Ford domination with its Torino Talladegas, Chrysler
responded late in the season with the Dodge Daytona and, in 1970, with the
Plymouth SuperBird. Marked by their controversial elongated noses and tall
wings in the rear, these cars pushed the aerodynamic envelope to the maximum
in a quest for all-out supremacy. After the 1970 season, engine size
restrictions imposed on the winged wonders ended their brief but massively
successful campaign. |
| |
|
| P |
|
AERODYNAMICS |
| |
the scientific discipline that
concerns itself with the principles of airflow over and around solid objects.
Aerodynamics helps engineers determine the shape the car so that it creates
maximum downforce while minimizing aerodynamic drag. |
| |
|
| P |
|
AERODYNAMIC DRAG |
| |
A number that is a coefficient
of several factors that indicates how well a race vehicle will travel through
the air and how much resistance it offers. Crewmen work to get the best
"drag horsepower" rating they can, determining how much horsepower
it will take to move a vehicle through the air at a certain mile-per-hour
rate. At faster speedways teams strive to get the lowest drag number possible
for higher straightaway speeds. |
| |
|
| P |
|
AIR DAM |
| |
A strip that hangs under the
front grill, very close to the ground. It helps provide downforce at the
front of the car. |
| |
|
| P |
|
AIR PRESSURE |
| |
With the advent of radial tires
with stiffer sidewalls, changing air pressure in the tires is used as another
setup tool that is akin to adjusting spring rates in the vehicle's
suspension. An increase in air pressure raises the "spring rate" in
the tire itself and changes the vehicle's handling characteristics. If his
race vehicle was "tight" coming off a corner, a driver might
request a slight air pressure increase in the right rear tire to "loosen
it up." |
| |
|
| P |
|
ALABAMA GANG |
| |
The nickname for Red Farmer,
brothers Bobby and Donny Allison, Bobby's late son Davey, and the late Neil
Bonnett. |
| |
|
| P |
|
ANTI-ROLL BAR |
| |
(Also
known as a Sway Bar) An metal bar approximately 1-inch diameter that connects
the outer ends of the suspension with the frame of the car. It's purpose is
to reduce the amount of side-to-side body roll during cornering. |
| |
|
| P |
|
APRON |
| |
The flat part of the racetrack
below the banking. The apron is not part of the racetrack and using it during
a race usually has one of two consequences. It either brings a penalty from
NASCAR race control or it'll likely cause a driver to spin if he or she is at
speed. |
| |
|
| P |
|
ASPHALT |
| |
One
of two different paving surfaces that NASCAR's top series race on (the other
being concrete). Basic asphalt is comprised of tar, asphalt, rock and
sand. |
| |
|
| P |
|
B-PILLAR |
| |
The
middle pillar that connects the roof to the body of the car. They are located
on both sides of the car, just behind the head of the driver. |
| |
|
| P |
|
BACK MARKER |
| |
A car running off the pace near
the rear of the field. |
| |
|
| P |
|
BACKSTRETCH |
| |
The
straightaway opposite of the start/finish line. On an oval, it usually
connects Turn Two with Turn Three. |
| |
|
| P |
|
BALANCE |
| |
When a car doesn't tend to
oversteer or understeer, but goes around the racetrack as if its on rails,
it's said to be in balance. |
| |
|
| P |
|
BANKING |
| |
The sloping of a racetrack,
particularly at a curve or a corner, from the apron to the outside wall.
Degree of banking refers to the height of a racetrack's slope at the outside
edge. |
| |
|
| P |
|
BIAS-PLY TIRES |
| |
Before radial tires were
sanctioned by NASCAR, bias-ply tires ruled the day. Bias-ply tires are
constructed with overlapping cords (or inner layers). Today, radial tires are
used by NASCAR teams because of their reduced rolling resistance and stronger
construction. |
| |
|
| P |
|
BLACK FLAG |
| |
The last thing a driver wants to
see, the black flag means that, for whatever reason, race officials say you
must pull into the pits immediately for a consultation. A driver can get the
black flag for many reasons, none of them good. |
| |
|
| P |
|
BLACK FLAG W/WHITE X |
| |
This flag means that a driver is
no longer being scored by race officials and must come into the pits
immediately. It's usually displayed because a driver has not acknowledged the
solid black flag displayed earlier |
| |
|
| P |
|
BUMP-DRAFT |
| |
A controversial technique often
employed by drivers at restrictor-plate races that has one car bumping
(ramming, really) the car immediately ahead. The goal of bump drafting is to
speed up the car ahead of you so you do not lose ground. |
| |
|
| P |
|
BUMP AND RUN |
| |
A controversial passing
technique most often used at short-tracks. The idea is that the driver behind
purposely brakes late going into a turn and allows his car to
"gently" bump the car in front just as they enter the turn. This
tap causes the car in front to slide up the track, clearing the way for the
car behind to pass below. |
| |
|
| P |
|
BUSCHWHACKER |
| |
A
Nextel Cup Series driver who races in a Busch Series race. |
| |
|
| P |
|
C-PILLAR |
| |
The rear-most pillars on both
sides of the car that extend from the roofline to the base of the rear
windshield. |
| |
|
| P |
|
CALIPER |
| |
The
part of a disk brake system that wraps around the disk and holds the
hydraulic mechanisms and brake pads in place. |
| |
|
| P |
|
CAMBER |
| |
Camber addresses the angle at
which a tire makes contact with the track surface. "Positive
camber" indicates the angle of the tire is tilted away from the
vehicle's centerline while "negative camber" indicates the tire is
tilted toward the centerline. A typical oval track setup would have positive
camber in the left front and negative camber in the right front to help the
vehicle make left-hand turns. |
| |
|
| P |
|
CAMSHAFT |
| |
A rotating shaft within the
engine that opens and closes the intake and exhaust valves in the engine. |
| |
|
| P |
|
CAR CHIEF |
| |
The title of the person on a
race team who is responsible for a car's preparation. The Car Chief is the
keeper of the checklist and is the man in charge when the car is in the
garage. When the car rolls out of the garage, he hands the reins over to the
Crew Chief. |
| |
|
| P |
|
CASTER |
| |
The
steering axis around which each front wheel rotates. This caster angle can be
perfectly vertical but is usually tilted rearward at the top for improved
handling. |

yellow flag waved by the flagman which tells the drivers they must slow down
immediately and that safe racing conditions no longer exist on the
track. |
| |
|
| P |
|
CHASE FOR THE NEXTEL CUP |
| |
The last 10 races of the Nextel
Cup season. Think of it as a playoff system by which the top 10 drivers -- or
all of those within 400 points of the leader -- in standings after the first
26 races are figuratively separated from the other racers and compete for the
Nextel Cup championship. |
| |
|
| P |

through the gearbox to facilitate gear shifts without damage. |
| |
|
| P |
|
CONCRETE |
| |
One of two different paving
surfaces that NASCAR's top series race on (the other being asphalt). Basic
concrete is comprised of cement, sand and gravel. Rain usually washes away
any rubber that accumulates during a race weekend, making the surface slippery
until more rubber can be rubbed in by cars circulating the track. |
| |
|
| P |
|
CONTACT PATCH |
| |
The part of the tire that's
actually touching the road. |
| |
|
| P |
|
CONTINGENCY AWARDS |
| |
See
those small stickers on the front fenders of the race cars? Those companies
whose stickers appear on a car will award the teams a little extra cash,
beyond the official race purse, if that team performs well on a race weekend.
A contingency award sponsor might pay for winning the pole position. Another
might pay for making "the move of the race" as determined by
journalists. |
| |
|
| P |
|
COOKIE-CUTTER TRACKS |
| |
The nickname for a common layout
of modern racetracks. Typically, they're tri- or quad-ovals, 1.5 miles in

side of one car made by the tire of another car. They're commonly found
during and after short track races. 2. The circular marks left on the
racetrack by a driver doing a celebratory burn out after winning a race. |
| |
|
| P |
|
DOWNFORCE |
| |
The air pressure traveling over
the surfaces of a race vehicle creates "downforce" or weight on
that area. In order to increase corner speeds teams strive to create
downforce that increases tire grip. The tradeoff for increased corner speeds
derived from greater downforce is increased drag that slows straightaway
speeds. |
| |
|
| P |
|
DRAFT |
| |
The aerodynamic effect that
allows two or more cars traveling nose-to-tail to run faster than a single
car. When one car follows closely, the one in front cuts through the air,
providing less resistance for the car in back. |
| |
|
| P |
|
DRAFTING |
| |
The practice of two or more
cars, while racing, to run nose-to-tail, almost touching. The lead car, by
displacing the air in front of it, creates a vacuum between its rear end and
the nose of the following car, actually pulling the second car along with it. |
| |
|
| P |
|
DRAG |
| |
The resistance a car experiences
when passing through air at high speeds. A resisting force exerted on a car
parallel to its air stream and opposite in direction to its motion. |

ROOF FLAPS |
| |
These flaps are sections at the
rear of a race vehicle's roof that are designed to activate, or flip up, if
the air pressure flowing across them decreases. In the case of a vehicle
turning backwards, the tendency for an uninterrupted flow of air is to create
lift. The roof flaps are designed to disrupt that airflow in attempt to keep
the vehicle on the ground. |
