Formula racing, or single-seat automobile racing in which car specifications are strictly regulated, is governed by FIA. Periodically, FIA sets technical regulations for building, maintaining, and racing many different classes of cars. The sophisticated vehicles used in Formula One (F1) racing are the most technologically advanced in racing. Their design causes air to flow over and under the car (aided by body features known as wings), creating a downward force that holds the car close to the ground even at high speeds. Designed for road racing, F1 cars can accelerate and brake quickly. FIA also regulates slower and less advanced single-seat cars competing in such categories as Formula Two (F2), Formula Three (F3), and the GP2 series, which was called Formula 3000 (F3000) prior to 2005.
