2005 FIA GT Championship

The 2005 FIA GT Championship season was the 9th season of FIA GT Championship motor racing. It featured a series of races for GT1 Grand Touring and GT2 Series Grand Touring cars, the former more powerful and highly developed and the latter remaining closer to the production models on which they were based. Additionally cars from National Championships (Group 2) and from Single-make Cups (Group 3) were permitted to participate in championship races but could not score points towards the various awards. The championship itself consisted of a GT1 Championship for Drivers, a GT1 Championship for Teams, a GT2 Cup for Drivers and a GT2 Cup for Teams. A Manufacturers Cup was also awarded in both classes. The championship season began on 10 April 2005 and ended on 25 November 2005 after 11 races.
