former lead Ferrari into the sandbank at Mulsanne corner, dropping it right down the order. Chinetti's own Ferrari moved up into the top five, while his 3rd car had fallen to clutch problems in the early evening, as had Rosier's car. Night Going into the night, Manzon and Behra kept their lead, and by midnight were a lap ahead of "Levegh" in his Talbot. However just before half-time one of the Gordini's brakedrums jammed and despite repairs the team considered too dangerous to risk continuing. This left "Levegh" sitting four laps ahead of the two Mercedes-Benzes of Helfrich / Niedermeyer and Lang / Riess, followed by the Macklin / Collins Aston Martin. But it was not an easy lead – he had already decided to drive right through on his own; the engine had developed a vibration and he did not want to risk his co-driver, René Marchand, with a breakdown.

It also caused Alexis Constantin to crash and roll his supercharged Peugeot at Tertre Rouge barely missing Jack Fairman's Allard.

As the sun rose, Neubauer instructed his drivers to finally pick up the pace, but it was too late, the lead was too great. "Levegh" had driven through the night and still held a good lead. Near noon a damaged wheel cost Helfrich time and dropped his car to third. Macklin and Collins kept their Aston Martin at a steady pace in fourth. Late in the morning the leading Frazer-Nash of "Dickie" Stoop / Peter Wilson broke a
