Four Porsche 911 GT3 R race cars will contest the 70th running of the 24 Hours of Spa. Regarded as one of Europe’s major long-distance classics alongside the 24-hour races of Le Mans and the Nürburgring, Spa marks round two of the Intercontinental GT Challenge and the fourth race of the Blancpain GT Series Endurance Cup. Porsche supports four customer teams with works drivers and engineers at the race on 28-29 July. Tackling the event are the two Porsche teams from the Blancpain GT Series Endurance Cup, Manthey-Racing and Herberth Motorsport, as well as the KÜS Team75 Bernhard and Black Swan Racing squads. Six current works drivers as well as the former factory driver and the current head of Porsche Customer Racing, Marc Lieb, form the driver crews in the four ca. 500 hp customer racers. For the marathon race in Belgium, 68 cars from 13 marques are entered. In addition to the 64 vehicles that comply with the FIA GT3 regulations, four other vehicles are registered, including three Porsche 911 GT3 Cup cars.
