If you're already confused by the myriad of categories - and different names for them - that make up the landscape of international GT racing, then be prepared for a new addition. The class is called GT2 and, no surprise, it's the brainchild of Stephane Ratel, the architect of GT3 and GT4, as well as the short-lived GT1 division of the early 2010s.
Ratel, the world's premier promoter of GT racing by some chalk, saw an opening - or rather a need - for a new class. His realisation was founded on the gradual disappearance of the amateur driver from many of the series he promotes around the world.
That's why he came up with the idea of a new breed of machinery that fits between the existing GT3 and GT4 categories he created back in the 2000s. Ratel wanted to create a class for cars that were easier to drive, and cheaper to buy and run.
