Sport Car

Single-seater (open-wheel) racing is a popular form of motorsport with cars designed specifically for high-speed racing.
The wheels are not covered, and the cars often have aerofoil wings front and rear to produce downforce and enhance adhesion to the track.
The best-known variety of single-seater racing, Formula One, involves an annual World Championship for drivers and constructors of around 18 races a year featuring major international car and engine manufacturers such as Ferrari, Mercedes-Benz (McLaren), BMW (Sauber), Toyota, Honda, and Renault in an ongoing battle of technology and driver skill and talent. Formula One is, by any measure, the most expensive sport in the world, with some teams spending in excess of $400 million per year. Formula One is widely considered to be the pinnacle of motorsports, with the F1 Drivers' Championship being one of, and the oldest among, only three World Championships awarded each year by the FIA (the others being the World Touring Car Championship and the World Rally Championship).
In North America, the cars used in the National Championship (currently Champcars and the Indy Racing League) have traditionally been similar to F1 cars but with more restrictions on technology aimed at helping to control costs. Other single-seater racing series are the A1 Grand Prix (unofficially often referred to as the "world cup of motorsport"), GP2 (formerly known as Formula 3000 and Formula Two), Formula Nippon, Formula Renault 3.5 (also known as the World Series by Renault, succession series of World Series by Nissan), Formula Three, Formula Palmer Audi and Formula Atlantic.
There are other categories of single-seater racing, including kart racing, which employs a small, low-cost machine on small tracks. Many of the current top drivers began their careers in karts. Formula Ford represents a popular first open-wheel category for up-and-coming drivers stepping up from karts.
