Group CN is a category of vehicles used in motorsport, introduced by the FIA in 1993 for sports car racing.[citation needed] Group CN cars are mainly used in hillclimbing championships or sports racing series. Group CM is a non-FIA class which is closely related to Group CN.
Major racing series
Group CN rules are applied to a variety of championships. Many championships alter the rules in their own way like the Radical European Masters and V de V championships.
The French-based V de V organisation features two FFSA Group CN based classes. The endurance championship is open for any chassis and engine within the regulations. The V de V organisation also features the Funyo Challenge open to Peugeot powered Funyo 4 or Funyo 5.
From 2022, the Indian Racing League has used Wolf GB08 "Thunder" models built to Group CN specification.[1]
National championships
A Group CN racing class exists in many countries, many of which utilize radicals. Examples are the Radical UK Cup which features the Radical SR3 and the Open España Prototipos.
GT & Prototype Challenge
Ran as part of the Benelux-based Supercar Challenge, the GT & Prototype Challenge allows Group CN classification cars to compete; current competitors include the Radical SR3 and Norma M20 FC.
