Inaugurated in 2006, the International GT Open features two races per weekend with identical points’ allocation – the first race on Saturday runs over 70 minutes, the second on Sunday over 50. Two drivers share the cockpit. One of the keys to success in the International GT Open is the stable technical regulations and the capping of costs, for instance through control tyres. The Super GT class for more powerful vehicles is based on the FIA GT2 regulations, the GTS category on the FIA GT3 rules. A handicap system ensures more gripping racing at the head of the field. The top three drivers of each race are handed a 15, ten or five second penalty respectively for the following race.

In the Super GT category, Porsche customer teams from Germany, France and Spain field the new Porsche 911 GT3 RSR, the top model of Porsche customer racing. The Italian and Austrian squads place their trust in the Porsche 911 GT3 R in the GTS class. The calendar of this attractive race series is made up of eight events on selective race tracks. One of them is the Nürburgring.
