Open wheel car - Wikipedia, the free encyclopedia (422 words) |
 | Open wheel car is a term for cars, usually purpose-built racecars, with the wheels located outside the car's main body, as distinct from cars which have their wheels below the body or fenders, in the manner of most street cars, stock cars, or touring cars. |
 | Some major races are held on temporary street circuits, and in the US many are held on oval "superspeedways"—most notably the famous Indianapolis 500 in Indianapolis, Indiana; speeds on these ovals can range in constant excess of 210-220 mph (335-350 km/h), and at Indianapolis in excess of 230 mph (370 km/h). |
 | The visibility of the wheels to the driver makes a high degree of precision possible in their placement; on the other hand, wheel-to-wheel contact is dangerous, particularly when the forward edge of one tire contacts the rear of another tire, and is suddenly and powerfully flung upwards. |
