Some NASCAR Terminology Explained (A-L)
Posted on October 16, 2010
If you want to better understand NASCAR then a good place to start is with the terminology and lingo.
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. 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. 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.” BACK MARKER A car running off the pace near the rear of the field. BALANCE When a car doesn’t tend to oversteer or Some NASCAR Terminology Explained (A-L)
