Technically, the Matra mechanics had replaced the gearbox housing on the winning car, which was against regulations. The officials decided not to disqualify the car unless someone protested, and no team did. It was a Porsche gearbox. Henri Pescarolo became only the third driver to win three Le Mans in a row, after Woolf Barnato (1928–30) and Olivier Gendebien (1960-62). Having won Le Mans those three years in a row, and then the World Championship (with nine wins out of ten), Matra announced its retirement from racing at the end of the season with mission accomplished.
