How does FIA GT1 differ from other GT racing such as ACO (Le Mans), ALMS, and LMES?
Peter Wright: All international GT racing cars are built to common technical regulations, agreed between the FIA and ACO. Whereas the ACO sanctioned series encourage Manufacturers to enter cars, the FIA GT1 Championship is for teams who are independent of the Manufacturers. Q: Why is it necessary to balance the performance of the cars in FIA GT1? PW: GT1 cars are based on road-going Grand Touring cars, and come in all shapes and sizes. There are front-engined and mid-engined cars, with V-12s, V-10s, and V-8s. The Technical Regulations allow certain modifications for racing and set out to be fair to all configurations, balancing the various sizes and types of engines, and the weight. However, to achieve close racing among the wide variety of cars, it was necessary to bring the performance of them closer together. The FIA therefore developed a Balance of Performance system that is based on exactly the same techniques and tools that the Manufacturers and top racing teams in Formula 1 use
