It was designed primarily for racing, and was an improvement of earlier models of the Ferrari 166, such as the 166 MM Barchetta.
[3] Small diameter tubing was gas welded to create the steel skeleton, which was later fastened to the car.
Large drum brakes were placed on the wheels to better the stopping power, something that Ferrari would continue for several years.
[3] The engine of one example updated to 195 S-spec received a boost from previous models, now producing 170 horsepower instead of 140.
The car originally had a single carburetor, but was later converted to a three-carburetor setup to match the other 166 MM Berlinettas in 1950 so that it could be raced.
It was then purchased by George Smith of Cincinnati, Ohio, a year later and then sold again in 1961 to Donald Williams.
Fred Leydorf then purchased the car and gave it a complete restoration along with an engine rebuild.
In 1972, the 166 Berlinetta was sold to John R. Bond of California where it would be featured on the cover of Road & Track in the late 1970s.
