The Ferrari Colombo Engine was a petrol fueled, water cooled, carburetted 60° V12 engine designed by Gioacchino Colombo and produced in numerous iterations by Italian automaker Ferrari between 1947 and 1988. The maker's first homegrown engine, its linear successor is the Lampredi V12, which it far outlived, the last Lampredi being made in 1959. Colombo, who had previously designed Alfa Romeos for Enzo Ferrari, placed bore centres at 90 mm apart, allowing for significant expansion. Displacements ranged from the diminutive debut that powered the 125S racer to the unit in the 1986 412i grand tourer. Significant updates were made in 1963 for the 330 series, featuring a redesigned block with wider, 94 mm, bore spacing. Enzo Ferrari had long admired the V12 engines of Packard, Auto Union, and Alfa Romeo (where he was long employed), but his first car, the 1940 Auto Avio Costruzioni 815, used a Fiat derived straight-8. Development of the V12 Colombo engine continued long after Colombo had been replaced by Aurelio Lampredi as the company's marquee engine designer. Although the Lampredi V12 was a real force for the company, it was Colombo's engine which powered Ferrari to the forefront of high-performance automobiles through the 1950s and 1960s. 125 The first Ferrari-designed engine was the V12 125, the work of Gioachino Colombo and assistants Giuseppe Busso and Luigi Bazzi. The engine's name, and the car powered by it, the 125 S sports racer, were derived from the tiny by cylinders. The single overhead camshaft 60° V design had one cam on each cylinder bank, two valves per cylinder, and three 30DCF Weber carburetors. A 7.5:1 compression ratio yielded at 6800 rpm. First appearing May 11, 1947, the engine allowed the company to claim six victories in 14 races that year. Colombo and Ferrari had designed the engine with Formula One regulations in mind, and introduced it the next year in the company's first F1 car, the 125 F1. This time, it was supercharged, in accordance with F1 dictates, for a total output of at 7,000 rpm. However, the single-stage Roots-type supercharger was incapable of producing the high-end power required to compete with the strong eight-cylinder Alfa Romeo 158 and four-cylinder Maserati 4CLT. Nevertheless, strong driving and a nimble chassis allowed the company to place third in its first outing, at the Valentino Grand Prix on September 5, 1948 and the company persevered in racing. For 1949, the
