The Lancia D50, designed by Vittorio Jano in 1954 for Formula One, incorporated groundbreaking features like using the engine as a stressed chassis member, off-center engine placement for a lower height, and side-mounted pannier fuel tanks for improved weight distribution and aerodynamics. Six units were produced, with two displayed in Italian museums. The D50 debuted with Alberto Ascari, achieving pole position and fastest lap, but faced clutch issues. After Ascari's death and Lancia's financial struggles, Scuderia Lancia's assets were transferred to Scuderia Ferrari. Ferrari modified and rebranded the car as the "Lancia-Ferrari D50" and later the "Ferrari D50". Under Ferrari, the D50, driven by Juan Manuel Fangio, won the 1956 World Championship of Drivers. Throughout its competitive life, the D50 participated in 14 World Championship Grands Prix, securing five wins.
