The FIA GT1 World Championship brings together nine luxury sports car brands, represented exclusively by two-car teams featuring Aston Martin, Audi, BMW, Ferrari, Ford, Lamborghini, McLaren, Mercedes and Porsche at the season-opening 2012 round in Nogaro this weekend.

Stephane Ratel, founder and CEO of SRO Motorsports Group, says the aim of the new-look championship was to create an exciting racing environment for teams and brands which would be easy for fans to follow.

"Each team exclusively running two cars of the same brand in a competitive world championship was the vision for 2012," Ratel said. "This is a clear format that the fans can relate to – as they do with Formula 1. To have Aston Martin, Audi, BMW, Ferrari, Ford, Lamborghini, McLaren, Mercedes, Porsche together in the FIA GT1 World Championship is an appetizing combination. I am pleased to say that at Nogaro this weekend, the vision will become a stunning reality.”
