The 1963 24 Hours of Le Mans was the 31st Grand Prix of Endurance in the 24 Hours of Le Mans series and took place on 15 and 16 June 1963. It was also the tenth round of the 1963 World Sportscar Championship season. Despite good weather throughout the race, attrition was high, leaving only twelve classified finishers. There were a number of major accidents, the most serious of which caused the death of Brazilian driver Christian Heins and bad injuries to Roy Salvadori and Jean-Pierre Manzon. This was the first win for a mid- or rear-engined car, and the first all-Italian victory – with F1 drivers Ludovico Scarfiotti and Lorenzo Bandini winning in their Ferrari 250 P. In fact, Ferrari dominated the results list filling the first six places, and the winners’ margin of over 200 km (16 laps) was the biggest since 1927.
