Oval track racing
Oval track racing is a form of motorsport that is contested on an oval-shaped race track. An oval track differs from a road course in that the layout resembles an oval with turns in only one direction, and the direction of traffic is almost universally counter-clockwise. Oval tracks are dedicated motorsport circuits, used predominantly in the United States. They often have banked turns and some, despite the name, are not precisely oval, and the shape of the track can vary.
Major forms of oval track racing include stock car racing, open-wheel racing, sprint car racing, modified car racing, midget car racing and dirt track motorcycles.
Oval track racing is the predominant form of auto racing in the United States. According to the 2013 National Speedway Directory, the total number of oval tracks, drag strips and road courses in the United States is 1,262, with 901 of those being oval tracks and 683 of those being dirt tracks. Among the most famous oval tracks in North America are the Indianapolis Motor Speedway, Daytona International Speedway and Talladega Superspeedway.
While bicycle racing on oval-shaped tracks predates by several decades the automobile racing of this form, the earliest oval track auto racing may have taken place in the United States around the turn of the twentieth century, with distance endurance trials from oval tracks making news in 1905, documenting a 52-second mile for example, and with a 1911 news report in Grand Rapids, Michigan warning would-be spectators of the dangers of uncontrolled wrecks.
Pack racing is a phenomenon found on fast, high-banked superspeedways. It occurs when the vehicles racing are cornering at their limit of aerodynamic drag, but within their limit of traction. This allows drivers to race around the track constantly at wide open throttle. Since the vehicles are within their limit of traction, drafting through corners will not hinder a vehicle's performance. As cars running together are faster than cars running individually, all cars in the field will draft each other simultaneously in one large pack. In stock car racing this is often referred to as "restrictor plate racing" because NASCAR mandates that each car on its two longest high-banked ovals, Talladega and Daytona, use an air restrictor to reduce horsepower.
The results of pack racing may vary. As drivers are forced to race in a confined space, overtaking is very common as vehicles may travel two and three abreast. This forces drivers to use strong mental discipline in negotiating traffic. There are drawbacks, however. Should an accident occur at the front of the pack, the results could block the track in a short amount of time. This leaves drivers at the back of the pack with little time to react and little room to maneuver. The results are often catastrophic as numerous cars may be destroyed in a single accident. This type of accident is often called "The Big One".
Oval track racing requires different tactics than road racing. While the driver does not have to shift gears nearly as frequently, brake as heavily or as often, or deal with turns of various radii in both directions as in road racing, drivers are still challenged by negotiating the track. Where there is generally one preferred line around a road course, there are many different lines that can work on an oval track. The preferred line depends on many factors including track conditions, car set-up, and traffic. The oval track driver must choose which line to use each time they approach a corner. On a short track in a 25-lap feature race, a driver might not run any two laps with the same line. Both types of racing place physical demands on the driver. A driver in an IndyCar race at Richmond Raceway may be subject to as many lateral g-forces (albeit in only one direction) as a Formula One driver at Silverstone.
Weather also plays a different role in each discipline. Road racing offers a variety of fast and slow corners that allow the use of rain tires. Paved oval tracks generally do not run with a wet track surface. Dirt ovals will sometimes support a light rain. Some tracks (e.g., Evergreen Speedway in Monroe, WA) have "rain or shine" rules requiring races to be run in the rain.
