investing much effort in their works programmes and supplying cars to customers; sports racers lost their close relationship to road-going sports cars in the 1950s and the major races were contested by dedicated competition cars such as the Jaguar C and D types, the Mercedes 300SLR, Maserati 300S, Aston Martin DBR1 and assorted Ferraris including the first Testa Rossas. Top Grand Prix drivers also competed regularly in sports car racing. After major accidents at the
1955 24 Hours of Le Mans and the
1957 Mille Miglia the power of sports cars was curbed with a 3-litre engine capacity limit applied to them in the World Championship from 1958. From 1962 sports cars temporarily took a back seat to GT cars with the FIA replacing the World Championship for Sports Cars with the International Championship for GT Manufacturers.

. This era was seen by many as the highpoint of sports car racing, with the technology and performance of the cars comfortably in excess of what was seen in Formula 1.
Homologation saw many out-and-out racing cars produced in sufficient quantities to see them classed as production vehicles; the FIA responded by placing more restrictions on even the allegedly production-based cars and placed draconian limits on the power available to prototypes – these prototypes of the late 1960s/early 1970s were comfortably quicker than contemporary Grand Prix machinery and for 1972 they were constrained to run much smaller engines to F1 rules, often de-tuned for endurance.

The ACO, organisers of the Le Mans 24 Hours, attempted to come up with a formula that would encourage more prototypes back to the race but would also be relatively economical – their Grand Touring Prototype rules in the late 1970s, based on fuel consumption rules, gave rise to two different varieties of sports car racing that were widely held to be a high point in the history of the sport.

2010 also saw the introduction of the Intercontinental Le Mans Cup (ILMC) by the ACO, featuring events in America, Asia and Europe. This in turn led the ACO & FIA to come together to create the FIA World Endurance Championship (WEC) starting in 2012. This new series replaced the ILMC and was a spiritual successor to the former FIA World Sportscar Championship.
In 2012, the Rolex Sports Car Series overhauled its Daytona Prototype class, allowing for production-based designs.

The reformatted Trans-Am Series remained stagnant, being heavily overshadowed by the SCCA's World Challenge, and failing to garner a television contract.

Other television changes include Speed Channel losing the rights to almost every series. The World Challenge was transferred to Versus, while the ALMS was transferred to an ESPN/ABC partnership.

In simplistic terms, sports-prototypes are two-seat racing cars with bodywork covering their wheels, and are as technically advanced and, depending on the regulations they are built to, as quick as or quicker than their single-seat counterparts. Although not widely known, sports-prototypes (along with Formula 1 cars) are responsible for introducing the most numbers of new technologies and ideas to motorsport, including rear-wings, ground effect 'venturi' tunnels, fan-assisted aerodynamics and dual-shift gearboxes. Some of these technologies eventually filter down to road cars.

, and offer a different interpretation of the prototype theme. DPs, as they are often called, are closed-cockpit, purpose-built racing machines which are less expensive and (deliberately) somewhat slower than Le Mans Prototypes, which were becoming dangerously quick on the Daytona oval and prohibitively expensive for smaller teams to run. Compared to the LMPs, DPs are severely limited in terms of approved technology; for instance, they are required to be constructed of steel tube frames with carbon-fibre skins, rather than being carbon-fibre monocoques, and must use production-based engines. In addition, contrary to their European counterparts who continuously alter and develop a vehicle to increase performance as a season progresses, DPs are restricted to their original conception of the car from the start of the season. For these reasons, the category being labeled as a "prototype" has occasionally been criticised as misleading and being more in line with traditional "spec" race series prevalent in the United States. The intention of the DP formula was to provide a class in which tight technical regulations encouraged close competition and where budget would be relatively unimportant. DP chassis are subject to a franchise-like approval system in which only approved constructors are eligible, with rules stability enforced for several years at a time, although this led in 2007 to established constructors like

Gran Turismo'') racing is the most common form of sports car racing, and is found all over the world, in both international and national series. Historically, Grand Touring cars had to be in series production, but in 1976 the class was split into production-based
Group 4 Grand Touring Cars
Group 4 referred to regulations for sportscars and grand touring (GT) cars used in racing and rallying, as regulated by the FIA. The group was introduced in 1954 and was replaced by Group B for the 1982 season.

races in the USA. When GT racing revived after the collapse of the World Sports Car Championship at the end of 1992, the lead in defining rules was taken by the ACO. Under the ACO rules, Grand Touring cars are divided into two categories, Grand Touring 1 (GT1, formerly GT) and Grand Touring 2 (GT2, formerly N-GT). As the name of the class implies, the exterior of the car closely resembles that of the production version, while the internal fittings may differ greatly. GT2 cars are very similar to the FIA GT2 classification, and are 'pure' GT cars; that is production exotic cars with relatively few internal modifications for racing. The

Cups but will open to other cars next year. This category is designed for privateer and rookie teams as an easier way to enter the series.
For 2011, the ACO split GT2 into two categories, GTE-Pro (for all-professional teams with current-spec cars) and GTE-Am (for teams with one amateur and one professional per car using previous-spec cars), as a way to entice rookies to enter one of the three Le Mans Series.
FIA divides GT cars into four categories called GT1 (formerly GT), GT2 (formerly N-GT), GT3 (recently introduced) and GT4. The GT1 and GT2 divisions are very close to the ACO rules outlined above, and again some crossover racing does occur, particularly in the GT2 class. The GT3 class is relatively new and was introduced for 2006. These cars are closer to standard form than in GT2, and in most cases modifications are restricted to those found in one-make cups. GT4 is another new category for non-professional drivers in production-based cars with very few racing modifications – for example, no aerodynamic aids or body modifications are permitted. All of the categories (with the exception of GT2) have their own championships/cups run by the FIA. Currently, GT2 is defunct in the FIA, and only runs in Le Mans Series/ALMS; however, the FIA has also announced that GT2 cars will be able to compete in the

Grand-Am has only one class for Grand Touring cars which allows production-based GT racers at a spec somewhere between FIA GT2 and GT3 in terms of modification (e.g. the Porsche 911 GT3 Cup) to compete with purpose-built tube-frame "silhouette" machines reminiscent of the former IMSA GTO/GTU classes. Grand-Am also runs various under-classes more reminiscent of GT4, though closer to factory cars. For 2012, GT3 cars will be allowed, with spec wings and splitters, as long as they pass a test at the NASCAR Research and Development Center in Concord, North Carolina, thus allowing GT3 cars to run with few modifications relative to other series (NASCAR, the parent company of Grand-Am, does not permit anti-lock brakes or traction control to be used on Grand-Am GT cars).

series divides cars into two classes, called GT500 and GT300. These cars are less restricted than their European and American counterparts, with cars often sporting tube frame clips and forced induction kits. Teams are also free to change engines with other models made by the manufacturer. The numbers in the classifications refer to the maximum power (in horsepower) available to each class; this is achieved through the use of engine restrictors. Proponents of the series claim that the Super GT cars are the fastest sports cars in the world, while critics deride the cars as being outside the limits of 'acceptable' modifications. In recent years however, rule changes in both GT500 and GT1 (aimed at eventually allowing both classes to compete with each other in the future) have brought the cars closer to each other, although GT500 cars still have a notable advantage in terms of aerodynamics and cornering performance (enough to compensate for GT1 cars greater power).
