It was adapted into a sports car for the street in the form of the 166 Inter. Only 12 Ferrari 166 S were produced, nine of them with cycle-fenders as the Spyder Corsa. It was soon followed by the updated and highly successful Ferrari 166 MM (Mille Miglia), of which 47 were made from 1948 to 1953. Its early victories in the Targa Florio and Mille Miglia and others in international competition made the manufacturer a serious competitor in the racing industry. Both were later replaced by the 2.3 L 195 S. Design The 166 shared its Aurelio Lampredi-designed tube frame and double wishbone/live axle suspension with the 125. Like the 125, the wheelbase was 2420 mm long. Nine 166 Spyder Corsas and three 166 Sports were built. The first two 166 S models were coachbuilt by Carrozzeria Allemano and the last one by Carlo Anderloni at Carrozzeria Touring. Majority of the 166 MM cars were bodied at Touring in a barchetta form. The 1.5 L Gioacchino Colombo-designed V12 engine of the 125 was changed, however, with single overhead camshafts specified and a larger 2.0 L (1995 cc/121 in³) displacement. This was achieved with both a bore and stroke increase, to 60 by 58.8 mm respectively. Output was at 5,600 rpm to at 6,500 rpm with three carburetors, giving top speed of . For the 166 MM power output rose to at 6,600 rpm and top speed to . Motor Trend Classic named the 166 MM Barchetta as number six in their list of the ten "Greatest Ferraris of all time". Racing The Ferrari 166 S won Targa Florio with Clemente Biondetti and Igor Troubetzkoy in 1948. In 1949, Biondetti also won in the 166 SC with Benedetti as co-driver. The 166 S won 1948 Mille Miglia, also driven by Biondetti, this time with Giuseppe Navone. In 1949 Mille Miglia, the Ferrari 166 MM Barchettas scored 1-2 victory with Biondetti/Salani and Bonetto/Carpani respectively. In 1949, the 166 MM also won the 24 Hours of Le Mans in the hands of Luigi Chinetti and Lord Selsdon, and so the 166 was the only car ever
