Enzo Ferrari was a race-car driver for Alfa Roméo. He stopped racing following the birth of the first of his two sons. Known as Dino, his elder son Alfredo was a mechanical engineer who died of muscular dystrophy at the age of 24. In 1956, the year of his death, he designed, with collaboration of Pinin Farina, the first Ferrari V6 rear-drive sports car. This type of engine had already been used in race cars, but never in a sports car.
