The Ferrari 166 MM Touring Barchetta is a car that was designed for long-distance competition. It was given the Mille Miglia appellation, which is one of the most well-known road events in the world. The majority of the 166 MM cars had barchetta bodies built at Touring.
The car's wonderfully curved and delicate lines had already won over the critics before it was shown at the 1948 Turin Motor Show in September.
The engine of the 166 MM was altered to use "normal" fuel. However, the 1.5 L V12 engine of the 125, which Gioacchino Colombo designed, was modified with single overhead camshaft carburetors, giving a top speed of 170-215 km/h (106-134 mph).
Power output for the 166 MM increased to 140 PS (103 kW) at 6,600 rpm, and the highest speed increased to 220 km/h (137 mph).
The 166 MM Touring Barchetta was created for competitive long-distance racing. Using the "Superlight" construction technique, Touring constructed its coachwork.
