The Ferrari Lampredi engine was a naturally aspirated all aluminum 60° V12 engine produced between 1950 and 1959. Inline-4 and Inline-6 variants for racing were derived from it. 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. Variants of his design powered the company to a string of world championships in the 1950s. All were quickly abandoned, however, with the Dino V6 and V8 taking the place of the fours and sixes and evolution of the older Colombo V12 continuing as the company's preeminent V12.
