Corvette's lone entry prevailed in an attrition-hit GTE Pro race, in which every other car hit mechanical trouble.
A qualifying crash forced the withdrawal of the #63 C7.R, but Oliver Gavin, Tommy Milner and Jordan Taylor picked up the baton in the #64.
An early pitstop delay for the #95 Aston Martin Racing Vantage and a dramatic fire for the #92 Manthey Porsche 911 RSR set the tone, and Corvette was left to duel with the two remaining AMR cars and the #51 AF Corse Ferrari for victory.
Two Astons became none overnight. The #97 Aston was first of the leaders to go, suffering an engine failure not long after night fell, and the #99 fell in the early hours of the morning when Fernando Rees crashed into an LMP2 car.
With Porsche's remaining #91 911 dropping out of contention with a gearbox leak in the 21st hour, Corvette and Ferrari were left in a straight fight for the win.
Gianmaria Bruni hit the front with two hours to go but a gearbox problem consigned the 458 Italia to a 30-minute stay in the pits and dropped it to third.
It meant Gavin had a clean run in the last hour and a half to end up five laps clear of the #71 Ferrari of James Calado, Davide Rigon and Olivier Beretta, which was out of victory contention early on when it lost four laps to get the alternator replaced.
The #95 Aston recovered to fourth, behind the #51 Ferrari but ahead of the #91 Porsche and #99 Aston.
What awesome advert for Chevrolet Corvette, it does not get much better than beating the worlds best supercars.
Wow Corvette not only beat the worlds best at Le Man they won by 5 laps, l hope Chevy Corvette advertise the hell out of this. Not only did Corvettes win they were the sweetest sounding cars at Le Man.
