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. V12 275 After little luck in Formula One with the supercharged Colombo V12, Ferrari moved to natural aspiration. The task of creating the new V12 for Formula One use fell to Aurelio Lampredi, who designed a 3.3 L (3322 cc) unit, with bore centres at 108 mm apart, for 275 S and 275 F1. The SOHC, 2-valve engine debuted in 275 S, as a test bed, with three Weber 40DCF carburettors, developing and was soon upgraded with 42DCF Webers for for F1. Applications: 1950 Ferrari 275 S 1950 Ferrari 275 F1 340 Being unable to match Alfetta 158 performance, Lampredi upgraded the design to 4.1 L (4101 cc) for 340 F1. Power output grew to but the single-seater was used in non-championship race only and very soon replaced by even bigger engined Ferrari. Like the Colombos, Lampredis engines found their way into road cars as well. The 1950 340 America and later 340 Mexico/MM were first with big 4.1 L (4101 cc) engines producing . All GT road cars used wet sumps, apart for dry-sumped 340 America having engine based directly on the 340 F1. Applications: 1950 Ferrari 340 F1 1950 Ferrari 340 America 1951 Ferrari 342 America 1952 Ferrari 340 Mexico 1953 Ferrari 340 MM 375 In the same year as 340 F1, the last Lampredi-designed F1 engine was inaugurated. Now at 4.5 L (4493 cc) and installed in 375 F1, Ferrari was finally able to beat Alfa Romeo, in the British Grand Prix at Silverstone. For the 1952 season Ferrari modified the 375 F1 for the Indianapolis 500 race. The bore was reduced by 1 mm (to 79 mm) for a total displacement below 4.4 L (4382 cc). New Weber 40IF4C carburettors improved power output to impressive . All Formula
