Ferrari 166 MM Spider Vignale

Chassis

# 0278M #0314M

Ferrari produced several variations of the 166, including the S, Corsa, and Mille Miglia, with odd serial numbers typically reserved for road cars and even serial numbers for competition cars. The final run of 13 MM chassis constructed in 1953 received a /53 designation, with updated spec to include 9.5:1 compression and a trio of massive Weber 36 IF/40 carburetors bumping output to about 160 horsepower. It also got a 120-liter fuel tank for endurance racing, all while keeping the weight below 1,800 pounds. These are the most potent variants of the 166 and, with just 13 produced, are highly sought after by collectors.

Vehicle Overview

On home soil in the Mille Miglia, the 166 earned its “MM” moniker and its place in the hearts of countless Italians. In the USA, the sports car racing scene was heating up, and wealthy gentleman drivers lined up for a chance to buy “previously enjoyed” Ferrari 166s from Chinetti’s newly formed North American Ferrari distributorship. Despite relatively low production numbers, the 166 amassed a tally of 88 victories between 1948 and 1955, putting it in rarified company among the winningest competition cars of all time.
