Automotive significance
Colombo had begun sketching the engine during the summer of 1945. By 1946 the project had become a compact 60-degree V12 with an oversquare bore-and-stroke relationship and a single overhead camshaft for each cylinder bank, with Giuseppe Busso and other engineers contributing as development continued. The first Ferrari-badged automobile belongs to the next chapter: this moment records the engineering foundation immediately before the 125 S appeared in 1947.
