AF Corse driver Robert Kubica was trying to put a lap on Dries Vanthoor in the seventh hour of the race when he side-swiped the BMW at the end of the Mulsanne straight, sending the car head-on into the barriers.
The contact with the armco sent Vanthoor spinning to the other side of the track, where he came to a rest with severe damage to the front of the car.
The #15 BMW retired immediately on the spot, with the race control deploying a safety car to help with the recovery of the vehicle.
The stewards began investigating the incident soon afterwards, but it wasn’t until after the safety car period had ended in the ninth hour that a decision was announced.
It was deemed that Kubica was responsible for the collision, with the #83 Ferrari 499P he shares with factory drivers Yifei Ye and Robert Shwartzman being handed a 30-second stop/go penalty.
The sanction has dropped the car from the lead of the race, as the safety car had bunched up the field and wiped out its entire lead - which stood at the best part of a minute at one point.
The #8 Toyota GR010 HYBRID of Ryo Hirakawa has moved to the front after Kubica took to the pitlane to serve the penalty.
