Group N-GT

The Group N-GT (National GT) (also known as Series Grand Touring Cars) was a motor racing category launched by the Fédération Internationale de l'Automobile in 2000. The first cars were homologated on 1 March, 2000 by Porsche and Ferrari. A total of eight different models from six marques were homologated throughout the class existence.

Appendix J article 257 of the International Sporting Code states the Series Grand Touring Car definition as follows: "An open or closed automobile which has no more than one door on each side and a minimum of two seats situated one on each side of the longitudinal centre line of the car; these two seats must be crossed by the same transversal plane. This car must be adapted for racing on circuits or closed courses." The engine must be fitted with a production based engine with a capacity of up to 8.0L. The restrictor size was determined based on the cylinder capacity and the weight of the car.^[1]

The Group N-GT regulations were used in various GT competitions, mostly as a secondary class to Group GT class cars. An N-GT class was added in the FIA GT Championship between 2000 and 2004. The class was later replaced by Group GT2 regulations. The Euro GT Championship and British GT Championship raced N-GT class cars in the same class alongside Group GT2 class cars and/or Group GT class cars.
