Corvette Racing's efforts to win the GT2 class on the 50th anniversary of Chevrolet's Le Mans debut have taken a blow after the second-placed car suffered a suspected engine failure.
The two works Corvettes had led the competitive GT2 category since the demise of the Risi Ferrari late on Saturday.
The No. 63 car was still on the same lap as the leading No. 64 machine and Antonio Garcia had just climbed aboard when it pulled off the road and stopped.
Johnny O'Connell, who had been sharing the car with Garcia and Jan Magnussen, told AUTOSPORT: "It's something in the engine. I don't know of any over-revs or anything like that. The thing about it is that it can happen to the No. 64 car, so they might back it off a bit."
The No. 77 Felbermayr Porsche is now up to second in GT2, just under two laps behind the remaining Corvette.
