STORY OF THE DAY: Merzario tests Ferrari’s radical snowplough prototype

Arturo Merzario tested the experimental Ferrari 312 B3 known as the Spazzaneve at Fiorano on 25 May 1972. This was a development test rather than a race, and the prototype never appeared in a World Championship Grand Prix. Its uncompromising shape made it one of the most distinctive studies produced during Ferrari’s search for a successor to the 312 B2.

The defining feature was its broad, wedge-shaped nose, which prompted the Italian nickname meaning “snowplough.” Moving the radiators from the nose toward the sides created space for a full-width front aerodynamic surface and concentrated more mass near the centre of the car. The experiment explored ideas that would influence later Ferraris even though this exact configuration was abandoned.

Designed under Mauro Forghieri, the Spazzaneve used Ferrari’s three-litre flat-twelve engine within a compact chassis. Side-mounted cooling, a low front profile and a substantial rear wing reflected Formula One’s rapid aerodynamic evolution in the early 1970s. Several concepts reappeared in developed form when Forghieri returned to direct Ferrari’s technical programme.

Arturo Merzario was an Italian driver who became closely associated with Ferrari in both sports cars and Formula One. Small in stature but notably versatile, he supplied valuable development feedback and made his World Championship debut for the Scuderia later in 1972. His role at Fiorano places him at the centre of an important experimental chapter rather than a conventional racing result.
