Porsche retained all six of its drivers for 2015. For the 6 Hours of Spa-Francorchamps and the 24 Hours of Le Mans, a third 919 Hybrid was entered for GT racers Earl Bamber and Nick Tandy and Force India Formula One driver Nico Hülkenberg. Webber and Hartley qualified the re-numbered No. 17 car on pole position, and Jani and Dumas's No. 18 car took second at the season-opening 6 Hours of Silverstone. 1 hour and 20 minutes in, Webber's No. 17 Porsche retired from the lead with a rear drivetrain failure. Jani, Lieb and Dumas's sister No. 18 car used its better acceleration and straight-line speed to exchange the overall lead with André Lotterer, Marcel Fässler and Benoît Tréluyer's No. 7 Audi in slower traffic over the rest of the race but lost the battle and finished second.
