The Group 3 racing class referred to a set of regulations for Grand Touring Cars competing in sportscar racing and rallying events regulated by the FIA. These regulations were active, in various forms, from 1957 to 1981.
Regulations for Grand Touring Car racing were first defined when the FIA issued "Appendix J" for Touring Cars and GT Cars in 1954. [1] The term Group 3 was in use by 1957 [2] and by 1960 a minimum production of 100 units [3] in 12 consecutive months was required to allow homologation into Group 3. [4] An FIA GT Cup [5] was instituted in 1960 [3] and the GT category was featuring prominently in most rounds of the World Sports Car Championship. [3] For 1962 the FIA replaced the World Sports Car Championship with an International Championship for GT Manufacturers, the new title being awarded each year through to 1965. [6]
The FIA introduced a new Group 3 Grand Touring Car category in 1966 as part of a major revision of the Appendix J regulations. [7] : 613 The production minimum required for Group 3 homologation was raised to 500 units and models such as the Ferrari 250 GTO and Porsche 904 were reclassified to the new Group 4 Sports Car category with its lower 50 unit minimum. [7] : 616 The International Championship for GT Manufacturers was discontinued for 1966 and replaced by the International Championship for Sports Cars. [6] GT cars were eligible to compete with the Group 4 cars in rounds of the International Championship for Sports Cars in 1966 and 1967 and then in the new International Championship for Makes with Group 4 Sports Cars and Group 6 Prototype-Sports Cars in 1968 and 1969. An International Cup for GT Cars was contested concurrently with the Makes Championship from 1968. [8]
The creation of a new Group 4 Special Grand Touring Car category in 1970 saw Group 3 renamed as Series Production Grand Touring Cars and the minimum production requirement increased to 1000 units. [9] Group 4, which allowed a greater degree of modification to the competing vehicles, had its minimum production requirement set at 500 units. [9] Both GT categories were eligible to compete in the International Championship for Makes and then, from 1972, in the renamed World Championship of Makes. The International Cup for GT Cars also continued. In 1976 the World Championship of Makes was restricted to production derived cars (FIA Groups 1 to 5) and the International Cup for GT Cars was discontinued in that year. [10]
The Group 3 Series Production Grand Touring Car category remained valid through to 1981 [11] with the FIA introducing a new Group B Grand Touring car category the following year. [12]
In rallying, there were classes for Group 1, Group 2, Group 3 and Group 4 cars. The Lancia Beta Coupé, was homologated into both Group 3 and Group 4, with the Group 3 car running the mass-produced 8-valve engine, and the Group 4 version running the more powerful 16-valve.

Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built prototypes or grand tourers based on road-going models. 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.
Group A is a set of motorsport regulations administered by the FIA covering production derived touring cars for competition, usually in touring car racing and rallying. In contrast to the short-lived Group B and Group C, Group A vehicles were limited in terms of power, weight, allowed technology and overall cost. Group A was aimed at ensuring numerous entries in races of privately owned vehicles.
A grand tourer (GT) is a type of car that is designed for high speed and long-distance driving, due to a combination of performance and luxury attributes. The most common format is a front-engine, rear-wheel-drive two-door coupé with either a two-seat or a 2+2 arrangement. Grand tourers are most often the coupé derivative of luxury saloons or sedans. Many iconic car models, such as the Ferrari 250 GT, Jaguar E-Type, and Aston Martin DB5, are considered classic examples of Gran Turismo cars.
Group B was a set of regulations for grand touring (GT) vehicles used in sports car racing and rallying introduced in 1982 by the Fédération Internationale de l'Automobile (FIA). Although permitted to enter a GT class of the World Sportscar Championship alongside the more popular racing prototypes of Group C, Group B are commonly associated with the international rallying scene during 1982 to 1986 in popular culture, when they were the highest class used across rallying, including the World Rally Championship, regional and national championships.
Super Touring, Class 2 or Class II was a motor racing Touring Cars category defined by the Fédération Internationale de l'Automobile (FIA) for national touring car racing in 1993. It was based on the "2 litre Touring Car Formula" created for the British Touring Car Championship (BTCC) in 1990. The FIA organised a World Cup for the category each year from 1993 to 1995, and adopted the term "Super Tourer" from 1995.
The International Sporting Code (ISC) is a set of rules applicable to motorsport governed by the Fédération Internationale de l'Automobile (FIA). North American domestic racing, such as NASCAR and IndyCar are outside the FIA's jurisdiction and hence not governed by the ISC. Motorcycle sport is also exempt since the Fédération Internationale de Motocyclisme (FIM) is responsible for this sport, not the FIA.
The 1982 World Sportscar Championship was the 30th season of FIA World Sportscar Championship racing. It featured the 1982 World Endurance Championship for Drivers, which was contested over an eight-round series, and the 1982 World Endurance Championship for Manufacturers, which was contested over five rounds held concurrently with the first five rounds of the Drivers Championship. The Drivers’ title was open to Group C Sports Cars, Group B GT Cars, Group 6 Two-Seater Racing Cars, Group 5 Special Production Cars, Group 4 GT Cars, Group 3 GT Cars, Group 2 Touring Cars and IMSA GTX, GTO and GTU cars. The Manufacturers title was limited to Group C Sports Cars and Group B GT Cars only. The series ran from 18 April 1982 to 17 October 1982.
The 1981 World Sportscar Championship season was the 29th season of FIA World Sportscar Championship motor racing. It featured the 1981 FIA World Endurance Championship which was contested over a fifteen race series which ran from 31 January to 27 September. The former World Challenge for Endurance Drivers was renamed to the World Endurance Championship of Drivers for 1981 and the World Championship of Makes was renamed to the World Endurance Championship of Makes. Bob Garretson won the World Endurance Championship of Drivers and Lancia was awarded the World Endurance Championship of Makes.
The 1978 World Sportscar Championship season was the 26th season of FIA World Sportscar Championship motor racing. It featured the 1978 World Championship for Makes, which was contested from 4 February to 3 September 1978 over an eight race series. The 24 Hours of Daytona and the 1000 km Nürburgring were part of the inaugural FIA World Challenge for Endurance Drivers.
Group 5 was an FIA motor racing classification which was applied to four distinct categories during the years 1966 to 1982. Initially Group 5 regulations defined a Special Touring Car category and from 1970 to 1971 the classification was applied to limited production Sports Cars restricted to 5 litre engine capacity. The Group 5 Sports Car category was redefined in 1972 to exclude the minimum production requirement and limit engine capacity to 3 litres. From 1976 to 1982 Group 5 was for Special Production Cars, a liberal silhouette formula based on homologated production vehicles.
The 1964 World Sportscar Championship season was the 12th season of FIA 'World Sportscar Championship' motor racing. It featured the 1964 International Championship for GT Manufacturers which was open to Group 3 GT cars and was contested from 16 February 1964 to 11 October 1964 over a twenty race series. Titles were awarded in three engine capacity divisions:
The 1969 World Sportscar Championship season was the 17th season of FIA World Sportscar Championship motor racing. It featured the 1969 International Championship for Makes, which was a series for FIA Group 6 Prototype Sports Cars, Group 4 Sports Cars and Group 3 Grand Touring Cars and the 1969 International Cup for GT Cars, which was restricted to Group 3 Grand Touring Cars. The season ran from 1 February 1969 to 10 August 1969 and comprised 10 races.
The 1976 World Sports Car Championship was a motor racing series open to Group 6 cars,. The championship was contested over a seven race series which ran from 4 April to 19 September and included a secondary award, the 1976 FIA Cup for Cars up to 2 Litres. 1976 was the 24th season of FIA World Sportscar Championship racing.
The Group 4 racing class referred to regulations for cars in sportscar racing, GT racing and rallying, as regulated by the FIA. The Group 4 class was replaced by Group B for the 1983 season.
Group 6 was the official designation applied by the FIA to two motor racing classifications, the Prototype-Sports Car category from 1966 to 1971 and the Two-Seater Racing Cars class from 1976 to 1982.
The Group 2 racing class referred to regulations for cars in touring car racing and rallying, as regulated by the FIA. Group 2 was replaced by Group A in 1982.
Group 7 was a set of regulations for automobile racing created by the Commission Sportive Internationale (CSI), a division of the modern Fédération Internationale de l'Automobile.
Group GT3, known technically as Cup Grand Touring Cars and commonly referred to as simply GT3, is a set of regulations maintained by the Fédération Internationale de l'Automobile (FIA) for grand tourer racing cars designed for use in various auto racing series throughout the world. The GT3 category was initially created in 2005 by the SRO Group as a third rung in the ladder of grand touring motorsport, below the Group GT1 and Group GT2 categories which were utilized in the SRO's FIA GT Championship, and launched its own series in 2006 called the FIA GT3 European Championship. Since then, Group GT3 has expanded to become the de facto category for many national and international grand touring series, although some series modify the ruleset from the FIA standard. By 2013, nearly 20 automobile manufacturers have built or been represented with GT3 machines.
The Group N-GT was a motor racing category launched by the Fédération Internationale de l'Automobile in 2000. The first cars were homologated on 1 March, 2000 by Porsche and Ferrari. A total of eight different models from six marques were homologated throughout the class existence.
Group GT1, also known simply as GT1, was a set of regulations maintained formerly by the Fédération Internationale de l'Automobile (FIA), for Grand Tourer racing. The category was first created in 1993, as the top class of the BPR Global GT Series, and was included in the 24 Hours of Le Mans. It fell under FIA regulation from 1997, after the BPR series came under the control of the FIA, becoming known as the FIA GT Championship. The category was dissolved at the end of 2011. The category may be split into four distinctive eras, from its debut in 1993–1996, 1997–1998, 2000–2009, 2010–2011.
