Aurelio Lampredi designed a number of racing engines for Ferrari. He was brought on to hedge the company's bets with a different engine family than the small V12s designed by Gioacchino Colombo. Lampredi went on to design a number of different Inline-4, Inline-6, and V12 engines through the 1950s, and it was these that would power the company's string of world championships that decade.
