The crash started when Jaguar driver Mike Hawthorn pulled to the right side of the track in front of Austin-Healey driver Lance Macklin and started braking for his pit stop. Macklin swerved out from behind the slowing Jaguar into the path of Levegh, who was passing on the left in his much faster Elektron magnesium-alloy bodied Mercedes-Benz 300 SLR. Levegh rear-ended Macklin at high speed, overriding Macklin's car and launching his own car through the air. Levegh's car skipped over a protective earthen berm at 200 km/h (125 mph) and made at least two impacts within the spectator area, the last of which caused it to disintegrate, throwing him onto the track where he was instantly killed, and sending large pieces of debris into the packed spectator area in front of the grandstand, including the engine block, front suspension, and bonnet. The rear of Levegh's car landed on the berm and exploded into flames.
