Group N

In relation to international motorsport governed by the FIA, Group N refers to regulations providing "standard" large-scale series production vehicles for competition.

They are limited in terms of modifications permitted to the standard specification by the manufacturer making them a cost effective method of production vehicle motorsport.

In many countries, there would often be two touring car championships, one for Group A and one for Group N. The category had some brief success with the demise of the Supertouring class in the late 1990s, when a few national regulations were relaxed to allow a greater number of modifications, in the guise of Super Production.

A Group N car has won a WRC rally once, a Renault 5 driven by Alain Oreille at the Rallye Côte d'Ivoire in 1989.

Popular cars used were often based on turbocharged, four wheel drive versions of standard consumer production cars such as the Subaru Impreza WRX and the Mitsubishi Lancer Evolution, although a wide range of vehicles were homologated by the FIA including small two wheel drive hatchbacks.

Furthermore, cars with forced induction engines were fitted with a restrictor in front of the charger to limit power.

There was provision for strengthening of the suspension components and bodyshell, provided this didn't alter the operating principle.
