An F1 car, or Formula One car, is an open-cockpit, single-seat racing car with the engine positioned directly behind the driver. The car is designed specifically for competing in Formula One racing events, which are governed by the Federation Internationale de l'Automobile (FIA).
As of 2014, FIA regulations specify that each car must weigh at least 691 kilograms (about 1,523 pounds), which includes the driver but not the fuel. Wheels must be made from one of two magnesium alloys permitted by the FIA. To protect drivers in the event of a rollover, it is required that each car include two roll structures, one positioned immediately behind the driver’s head, and the other positioned at the front of the cockpit ahead of the steering wheel.
