The Ferrari 166 MM, a racing sports car produced by Ferrari from 1948 to 1953, was a variant of the Ferrari 166, with MM standing for Mille Miglia. Presented alongside the 166 Sport at the 1948 Turin Motor Show, the 166 MM's early models were bodied by Touring, with later additions from Vignale, Pininfarina, and others. A unique model appeared in the Mille Miglia in 1953 and 1954 and was used in a Kirk Douglas film in 1955, built by Carrozzeria Autodromo Modena. A total of 46 vehicles were produced by 1953, primarily for motorsport. The 166 MM marked Scuderia Ferrari's first international success in sports car racing, symbolizing the start of the Italian team's success story. It participated in 269 races from 1949 to 1959, achieving 31 overall and 43 class victories.
