In relation to motorsport governed by the FIA, Group A referred to a set of regulations providing production-derived vehicles for outright competition. In contrast to the short-lived Group B and Group C, the Group A referred to production-derived vehicles limited in terms of power, weight, allowed technology and overall cost. Group A was aimed at ensuring a large number of privately-owned entries in races.
Under Group A in the World Rally Championship, the cars used were modified road cars, often based on turbocharged, four wheel drive versions of small cars such as the Lancia Delta Integrale, Toyota Celica GT-Four, Ford Escort RS Cosworth, Nissan Pulsar GTI-R, Subaru Impreza WRX and the Mitsubishi Lancer Evolution.
In order to be homologated, manufacturers were required to produce 5,000 units worldwide, and then in 1993 this number was reduced to 2,500. The cars are further modified for greater power and torque, and fitted with suspension and tyres specifically suited to the conditions of the specific rally, which may take place entirely on asphalt roads, different consistencies of gravel and dirt roads and even snow/ice-covered roads on some rallies held in northern Europe.
By 1990, Group A cars exceeded the performance of the Group B cars on many events, because although they had far less power they had better handling and traction. They were also much safer.
Group A is still used as the basis for most rally competitions around the world, but the most competitive cars are limited-production prototypes, known as Kit car, World Rally Cars, Super 1600 and Super 2000.
The last WRC car to use the old Group A homologation requirement was the Mitsubishi Lancer Evolution VI.
