Ferrari achieved one of its earliest competition milestones at the 1948 Mille Miglia, when Clemente Biondetti and his mechanic Navone drove a 166 Sport to overall victory.

The manufacturer soon honored its triumph with a new designation for a more purpose-built 166 variant called the 166 MM.

Thirty-four examples of the 166 MM were built in a first series through late 1951 before being supplanted by a short run of 13 second-series cars with 2-liter V-12 engines, half of which were clothed with spider coachwork by Vignale.

The new spider featured a more rounded version of Michelotti’s original design highlighted by recessed headlamps, upward-cut front fenders, cut-down doors, and cut-away rear fenders for improved brake cooling.

Intended primarily for privateer racing customers, the second-series 166 MM examples were exceedingly rare, and they constituted an important historical bridge between the early 166 model and the forthcoming 212.
