# Group A
**Group A** is a FIA classification for touring and grand touring cars derived from series-production road cars, introduced in the early 1980s as part of a new Appendix J to the International Sporting Code and used as the top technical category of the [World Rally Championship](https://www.edgepedia.org/world-rally-championship) from 1987 to 1996.[1](https://www.evo.co.uk/rallying/20384/the-anatomy-of-a-group-b-rally-car-history-and-tech-of-rallyings-golden-era) • [2](https://www.wrc.com/en/misc/wrc-history) It sits between Group N, a lightly modified showroom class, and the far more open [Group B](https://www.edgepedia.org/group-b) prototype category that preceded it as the championship's leading class.[3](https://motorsportformentalhealth.com/2026/06/14/london-concours-2026-group-a-rally/)

## Origins in the new Appendix J
The early 1980s saw a wholesale reorganization of international motorsport classification, with new Group N, A, B, and C rules replacing the Group 1 to 6 regulations that had held sway for decades.[1](https://www.evo.co.uk/rallying/20384/the-anatomy-of-a-group-b-rally-car-history-and-tech-of-rallyings-golden-era) The preceding 1981 Appendix J still listed the old structure: series-production touring cars (Group 1, 5,000 units), touring cars (Group 2, 1,000), series-production grand touring cars (Group 3, 1,000), grand touring cars (Group 4, 400), special production cars (Group 5), and racing cars (Group 6).[10](https://www.fia.com/sites/default/files/regulation/file/Appendix%20J%201981_full-e.pdf)
**A late and contested arrival.** The introduction of the new Appendix J was, as with the 1966 version before it, a "down to the wire" affair, with draft detailed technical regulations only available late in 1981.[11](https://www.motorsportforums.com/archive/index.php/t-28835.html) The first major event under the new regulations, the 1987 [Monte Carlo Rally](https://www.edgepedia.org/monte-carlo-rally), brought controversy: a works Sierra V6 4x4 was excluded for having L-Jetronic injection instead of K-Jetronic, and there were complaints over "sliding/extending" bumpers on works [Lancia Delta](https://www.edgepedia.org/lancia-delta) 4x4s fitted to accommodate studded snow tires.[11](https://www.motorsportforums.com/archive/index.php/t-28835.html)
## The homologation basis
Group A was built around a high production requirement. Group N and A cars had to be built in 5,000 units or more, with Group N in particular allowing very little scope for performance modification and requiring cars to adhere to certain interior measurements and have at least four seats.[1](https://www.evo.co.uk/rallying/20384/the-anatomy-of-a-group-b-rally-car-history-and-tech-of-rallyings-golden-era)
The contrast with Group B was deliberate. Group B had cut the required production of the base vehicle to 200 units, with a further 20 rally versions sufficient for FIA recognition, which allowed mid-engined, turbocharged four-wheel-drive cars such as the Peugeot 205 Turbo 16 and [Lancia Delta S4](https://www.edgepedia.org/lancia-delta-s4) to be built on compact-car bases.[12](https://toyotagazooracing.com/jp/wrc/special/2018/the-wrc-chronicle-02/) Group A, by contrast, produced cars much closer to their factory showroom counterparts, which helped endear the championship to its growing fanbase.[4](https://www.autosport.com/wrc/news/how-iconic-cars-from-each-wrc-era-compare-at-the-hands-of-petter-solberg/10509922/)
## The WRC top category, 1987 to 1996
With Group B outlawed after the 1986 season, the FIA needed a new class structure for 1987 onwards, and Group A moved up to become the championship's leading category.[2](https://www.wrc.com/en/misc/wrc-history) The new regulations brought a generation of rally cars derived from production models: the Lancia Delta Integrale, Mitsubishi Lancer Evolution, Ford Escort Cosworth, and [Toyota Celica GT-Four](https://www.edgepedia.org/toyota-celica-gt-four) all graced the stages.[2](https://www.wrc.com/en/misc/wrc-history) The World Rally Championship also gave birth to the Lancia Delta HF Integrale, Ford Escort RS Cosworth, and Toyota Celica GT-Four, among others.[6](https://www.drivingline.com/articles/origin-story-of-the-wrx-nissan-skyline-gt-r-and-mitsubishi-lancer-evolution/)
The Lancia Delta Integrale became the archetypal Group A rally car and the most successful single model in rallying history, carrying Lancia to six consecutive constructors' championships.[5](https://www.carthrottle.com/post/wexe6yr) The mid-1990s Group A period included the [Subaru Impreza](https://www.edgepedia.org/subaru-impreza), associated with the late [Colin McRae](https://www.edgepedia.org/colin-mcrae), alongside the successful [Mitsubishi Lancer](https://www.edgepedia.org/mitsubishi-lancer) and Ford Escort Cosworth.[13](https://api.fia.com/news/future-regulations-across-multiple-categories-confirmed-during-world-motor-sport-council)
**Replacement in 1997.** The 2015 season marked the 20th anniversary of the last year the World Rally Championship was run exclusively under Group A rules, dating that final season to 1996.[5](https://www.carthrottle.com/post/wexe6yr)
## Group A today
Group A remains part of the FIA rulebook. The 2026 Appendix J includes Article 251 on classification and definitions, Article 252 on general prescriptions for cars of Group N, A (and extensions) and R-GT, and Article 253 on safety equipment for Groups N, A, and RGT.[9](https://www.fia.com/regulation/category/117)
**Historic rallying.** Group A cars occupy a defined place in FIA historic competition. In the European Historic Rally Championship, Category 4 covers Touring (T), Competition Touring (CT), Grand Touring (GT), and Competition Grand Touring (GTS) cars of Groups A, B, and N homologated between 1/1/1982 and 31/12/1987 (Period J1) and between 1/1/1988 and 31/12/1992 (Period J2), while Category 5 covers turbo 4WD Group A models homologated between 1/1/1993 and 31/12/2000.[7](https://api.fia.com/sites/default/files/2026_fia_european_historic_rally_championship_ehrc_gravel_-_sporting_regulations_clean_0.pdf) In the FIA European Historic Gravel Rally Championship, Category 5 groups turbo 4WD Group A and [World Rally Car](https://www.edgepedia.org/world-rally-car) models homologated 1993 to 2000, with class A8A for cars up to 2000 cm3 with a 34 mm turbo restrictor, including active transmission components for 1995 to 2000 specification cars, and Category 6 covers 2WD Group A cars homologated in the same 1993 to 2000 window.[8](https://portal.fpak.pt/pub/doc/2756/371100)
A 2024 World Motor Sport Council decision extended historic eligibility forward: from 2025, racing cars built between 1991 and 2000 can carry Historic Technical Passports, bringing the classic mid-1990s Group A period, including the Group A Subaru Impreza, Mitsubishi Lancer, and Ford Escort Cosworth, back into FIA championships and international motor sport events.[13](https://api.fia.com/news/future-regulations-across-multiple-categories-confirmed-during-world-motor-sport-council)
## Group A compared with its neighbors
The three groups of the 1982 to 1996 era served distinct purposes. Group N was a very lightly modified grassroots class; Group A was a class for modified production cars; and Group B was a much more open prototype class with very few restrictions and a tiny homologation production requirement.[3](https://motorsportformentalhealth.com/2026/06/14/london-concours-2026-group-a-rally/) Group A cars made up the numbers in WRC fields and were more closely related to production cars, while Group N was widely understood as the clubman class for grassroots competitors and upcoming drivers.[14](https://www.pistonheads.com/features/ph-features-motorsport/modern-rally-cars--a-spotters-guide/34055)
