Built between 1956 and 1959 on the long chassis (2,600 mm wheelbase). The car earned its unofficial but famous nickname after winning the grueling, multi-day Tour de France Automobile race four years in a row (1956–1959). Approximately 77 to 79 units were built, spanning four different body series (distinguishable by the number of air vents or louvres on the rear roof pillar).
