FIA divides GT cars into four categories called GT1 ( formerly GT ), GT2 ( formerly N-GT ), GT3 ( recently introduced ) and GT4.

Currently, GT2 is defunct in the FIA, and only runs in Le Mans Series / ALMS ; however, the FIA has also announced that GT2 cars will be able to compete in the FIA GT1 World Championship in 2012 in a World Class along with GT3 cars.

GT1 has been all but phased out with the removal of the class from the FIA GT1 World Championship.

GT3, the most popular of the GT classes, is used by the FIA GT1 World Championship, FIA GT3 European Championship, Blancpain Endurance Series, and most national series such as ADAC GT Masters or the British GT Championship.

Rising costs coupled with declining entries led to the death of this class, and it was replaced by what was then GT2 ( FIA, which evolved into the current GT1 ) and Le Mans Prototype ( LMP, by the ACO ).

Replaced by the FIA GT1 World Championship in 2010.
