Group CN
In sports car racing, the CN group describes a very specific processing standard for vehicles. Its regulations are determined by Article 259 of the FIA's International Sports Law . These vehicles are mainly used in mountain championships such as the EBM and in national sports prototype championships.
Technical regulations
Group CN vehicles are defined as two-seater, open or closed racing cars. In contrast to formula vehicles, however, all parts of the vehicle must be covered with a body. This can be a maximum of 2 m wide, 4.8 m long and 1.03 m high.
The engines come from group N and have a maximum displacement of 3,000 cm² and a maximum of 6 cylinders.
Well-known manufacturers
In addition to the well-known manufacturers, “self-made constructions” also appear in the programs and winners lists. These can actually be produced in-house, whereby the hurdles for meeting the security requirements are high. In some cases, however, prefabricated chassis are also supplied, and the manufacturer does not mention his name. It depends on the contract between the racing team and the supplier.
Lesser known manufacturers build one or two vehicles, and they drive as long as they can. The season can be over after a serious accident. Then the driver has to wait until a new vehicle is built.
