The Gioacchino Colombo V12 was bored out to provide a bigger displacement. The chassis was inspired by that of the 166 MM, with modifications aimed at transmitting the higher power output to the road. The later versions saw the introduction of a tubular chassis known as the ‘Tuboscocca’, which increased structural rigidity.
