team. However, his debut at the blue riband Daytona 24 Hours was thwarted by an engine failure on his Spirit of Daytona Crawford-Pontiac. In 2007 Primat signed for Henri Pescarolo's eponymous team. A podium finish at Spa was his best result in the face of increased competition from the works Peugeot squad, but Primat finished in the top six at four of the six races. The season also saw him finish Le Mans for the first time, finishing sixth in class and 13th overall despite losing 90 minutes in the pits to an oil leak. Remaining with Pescarolo Sport for the 2008 Le Mans Series, Primat had a top-three finish at Monza, despite the addition of the factory Audi squad to the LMS field. Primat also took a best-yet seventh-place finish at Le Mans, which placed him first among the unofficial 'petrol' class, beaten only by the diesel machines of sportscar heavyweights Audi and Peugeot. In January 2009 Harold was confirmed as an Aston Martin Racing factory driver for the brand's first return to top-class endurance racing since 1989. Partnering Darren Turner, he finished fourth in the Le Mans Series standings, including a second position at the Nürburgring. Primat was joined by Peter Kox and Stuart Hall for Le Mans, where a water leak curtailed the #009 Lola-Aston Martin's involvement after 252 laps. The highlight of Primat's season was victory alongside Stefan Mücke at the inaugural Asian Le Mans Series race at Okayama in late autumn. 2010 saw Primat again driving for Aston Martin Racing, recording three podium finishes in the ALMS and LMS. Sixth place overall at Le Mans itself also represented his best finish at the French race to date. A third season with AMR in 2011, this time alongside Turner and Mücke, produced two more top three finishes for Primat, including an outright ALMS victory at Laguna Seca. Aston Martin's new, open-top AMR-One proved unreliable however, prompting the team to withdraw from the LMP1 ranks at the end of the year. Primat then moved to privateer LMP1 outfit Rebellion Racing for the newly revived FIA World Endurance Championship in 2012. With Audi and Toyota's factory entries winning all eight rounds between them, it was left to Rebellion to fight for the LMP1 Trophy against Strakka, JRM and OAK Racing. Two victories by Primat - at Silverstone and Shanghai - brought the trophy to Rebellion. In 2013 Primat
