In the trio of qualifying sessions held to determine the grid for the 24 Hours of Le Mans, Hartley's No. 20 vehicle set the first session's fastest lap, but the car fell to fourth the next day despite Bernhard improving its lap time in the second session. Jani's No. 14 car was second after the first session, maintaining it through the remaining two sessions as Dumas twice bettered its lap. The No. 20 entry failed to finish enough laps for classification due to a broken anti-roll bar, and fuel pressure and gearbox problems left the No. 14 car in eleventh overall. For the 6 Hours of Circuit of the Americas, Jani and Dumas qualified the No. 14 car second despite a transgression of energy recovery system limits nullifying one of Jani's laps; Hartley and Webber's No. 20 entry took third. In a race that was red flagged for 77 minutes because of a thunderstorm flooding the Circuit of the Americas, Jani overtook the Toyota cars to lead at the restart, but a loss of engine power left the No. 14 car in fourth. Bernhard aquaplaned and beached the No. 20 car in a gravel trap, but he, Webber and Hartley finished fifth.
