The FIA GT1 World Championship was a world championship sports car racing series, developed by the SRO Group and regulated by the Fédération Internationale de l'Automobile (FIA), that was held from 2010 to 2012. It featured multiple grand tourer race cars—based on production road cars and conforming with the GT1 (2010–2011) and GT3 (2012) regulations—that competed in one-hour races on multiple continents. All cars were performance balanced, with weight and restrictor adjustments, to artificially equalise their performance. Championships were awarded each season for drivers and teams.
The FIA GT1 World Championship started in 2010 as a successor to the FIA GT Championship, which had featured the GT1 category as well as a GT2 category. In 2012, the series originally planned to move away from exclusive use of GT1 cars by allowing 2009-spec GT2 cars from the former FIA GT Championship, as well as current performance-balanced GT3 specification cars, to compete alongside the series' GT1 cars. However, as there were no interested GT2 teams and only a handful of former GT1 runners were willing to participate, the SRO Group decided that the 2012 season would be contested with GT3-spec cars only (yet retaining GT1 in the series' title). The series folded after the 2012 season due to the high costs, shrinking car counts, and issues with the calendar, and morphed into the FIA GT Series for 2013.
