Sports prototype

Last updated • 2 min readFrom Wikipedia, The Free Encyclopedia

A sports prototype, sometimes referred to simply as a prototype, is a type of race car that is used in high-level categories of sports car racing. They are purpose-built auto-sports race cars, as opposed to production-car based or street-legal, low-volume homologation specials – thus entirely not intended for consumer purchase, or production beyond the fabrication of the (nearly) unique cars entered into races and in race-car competition classes or "formulas", with sufficiently open regulations to allow for vehices of unique design to partake.

Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: grand tourers (GT cars), which are strictly based on production street cars, and sports prototypes, which are allowed a great amount of flexibility within set rule parameters.

From the 1953 season to 1984, the World Sportscar Championship titles were awarded to manufacturers of sports prototypes (except 19781981). From 1985 to 1992, titles were awarded to teams entering sports prototypes.

In historic racing, they are often called "sports racing cars". Sometimes, they are metonymically referred to as "Le Mans cars", as the 24 Hours of Le Mans has been closely associated with the category in recent decades and features entries from several of the main championships contested by prototypes.

Types of sports prototypes

Since the 1960s, various championships have allowed prototypes to compete. However, most championships have had their own set of rules for their prototype classes. Listed here are some of the more commonly known types of prototypes.

Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels.

Sports car racing is one of the main types of circuit auto racing, alongside open-wheel racing, touring car racing and stock car racing. Sports car races are often, though not always, endurance races that are run over particularly long distances or large amounts of time, resulting in a larger emphasis on the reliability and efficiency of the car and its drivers as opposed to outright car performance or driver skills. The FIA World Endurance Championship is an example of one of the best known sports car racing series.
