1950 Ferrari 275 S Fontana Barchetta

The new 3.3 liter Lampredi V12 engine got its first job powering the Ferrari 275 S sports car. Two different models were built with Touring barchetta bodies.


This 275 S was the first Ferrari to retain the upcoming Lampredi V12 and in 1950 this car raced alongside the only other 275 S in the Millia Miglia. Unfortunately the car did not finish the race (both cars had transmission difficulties due to the very powerful engine).A year later the engine and mechanicals were updated to 340MM spec and tried around the Millia Miglia road course. Again, little success was had. After Targa Florio of the same year, the car was rebodied by Fontana. With the new body, the car again raced Millia Miglia in 1953 and 1954 with little success.
