A typical open-wheeler has a minimal cockpit, sufficient only to enclose the driver's body, with the head exposed to the air. In the [[Whelen Modified Tour]] and other short track modified series, the driver's head is contained in the car. In modern cars, the engine is often located directly behind the driver and drives the rear wheels; except in [[asphalt modified]] cars, such as the [[Whelen Modified Tour]], where the engine is in front of the driver. Depending on the rules of the class, many types of open-wheelers have [[Spoiler (automotive)|wings]] at the front and rear of the vehicle, as well as a very low and virtually flat [[undertray]] that helps achieve additional aerodynamic [[downforce]] pushing the car onto the road. While many other categories of racing cars produce downforce, the top categories of open-wheel racing cars (particularly [[Formula One]] and [[IndycarIndyCar]]) produce far more downforce relative to their mass than any other racing category, allowing much higher corner speeds on comparable tracks.
 
Some major races, such as the [[Singapore Grand Prix]], [[Monaco Grand Prix]] (sanctioned by [[Formula One]]) and the [[Long Beach Grand Prix]] (sanctioned by [[IndyCar]]), are held on temporary [[street circuit]]s. However, most open-wheel races are on dedicated [[road course]]s, such as [[Watkins Glen International|Watkins Glen]] in the US, [[Nürburgring]] in [[Germany]], [[Spa-Francorchamps]] in [[Belgium]] and [[Silverstone Circuit|Silverstone]] in [[Great Britain]]. In the United States, some top-level open-wheel events are held on ovals, of both short track and superspeedway variety, with an emphasis being placed more on speed and endurance than the maneuverability inherently required by road and street course events. The [[Whelen Modified Tour]] is the only opened wheeled race car series endorsed by [[NASCAR]]. This series races on most of NASCAR's most famous tracks in the United States. Other asphalt modified series race on short tracks in the United States and Canada, such as [[Wyoming County International Speedway]] in New York. The best-attended oval race in the world is the annual [[Indianapolis 500]] (Indy 500) in [[Speedway, Indiana]], sanctioned by IndyCar; in the [[United States]], it is quite common to refer to open-wheel cars as IndyCars, or Champ Cars, because of their recognizable appearance and widespread popularity across America at the Indy 500.
