Gioacchino Colombo
Gioacchino Colombo (9 January 1903 – 24 April 1988) was one of the most consequential engine designers in Italian motorsport history — the man who created the Alfa Romeo 158 Alfetta engine that would win Formula One’s first two world championships, and then, almost simultaneously, designed the Ferrari V12 that would eventually challenge it. Born in Legnano, he was a technical draftsman by his mid-teens at the Officine Franco Tosi, working on diesel engines, steam turbines, and submarines — an unusual foundation for a future racing engine designer. By 21 he had joined Alfa Romeo and entered Vittorio Jano’s design team, working as an apprentice on the Alfa Romeo P2 Grand Prix car programme and absorbing Jano’s architectural principles: supercharged straight-eights, twin-cam construction, light alloy, hemispherical combustion chambers.
Colombo spent over a decade learning from Jano and developing his own authority as an engineer. By 1937 Jano had departed for Lancia, and Colombo was the continuity at Alfa Romeo. That year, at Enzo Ferrari’s explicit request — Ferrari was then managing the works racing operation through Scuderia Ferrari and was already planning for the forthcoming 1.5-litre voiturette formula — Colombo designed what would become the Alfa Romeo 158: a straight-eight, twin-overhead-cam, 1,500 cc engine with a single-stage supercharger fed by a triple-choke carburettor, initially producing 200 bhp at 7,000 rpm. The car that carried it was christened the Alfetta (“Little Alfa”). It debuted at Livorno in August 1938, Emilio Villoresi winning. Colombo was then named head of the Alfa Corse design department, overseeing the 158’s development through the years leading to WWII. When Germany occupied northern Italy, a small group of Alfa Romeo technicians and labourers took it upon themselves to protect the irreplaceable machines. Working clandestinely, they loaded the 158s onto trucks and smuggled them out of the Portello factory to hiding places including a farmhouse at Abbiategrasso — behind false walls and stacks of logs, scattered across the countryside beyond German reach. Achille Castoldi, the 1940 world water speed record holder, cared for one of the cars and later used a 158 engine in his record-setting hydroplane. The cars that won the 1950 and 1951 Formula One World Championships were these same physical machines — preserved, developed, and brought back to life.
After the war, Alfa Romeo briefly suspended Colombo amid the post-war dislocation, and Enzo Ferrari was waiting. Ferrari commissioned Colombo to design a new V12 engine for his fledgling company’s road and racing cars. The “Colombo V12” — a compact, short-block 1.5-litre design capable of scaling to almost any displacement — became the direct ancestor of Ferrari’s race-winning engines for four decades: used in the 166 MM that won Le Mans in 1949 and in the 125 F1 that Ferrari entered in that year’s world championship races. Colombo returned to Alfa Romeo from 1950 to 1952 — overseeing development of the 158 into the 159 specification that carried Juan Manuel Fangio to the 1951 World Drivers’ Championship — then went to Maserati in 1953, where he created the 250F Grand Prix car. Fangio drove the 250F to his third world championship in 1957. A brief Bugatti engagement followed, and then Colombo drifted out of front-line racing. Over a career spanning four manufacturers and more than three decades, he claimed authorship of more than 110 engines.
