The Ferrari 340 MM was a Ferrari race car.
It was a more powerful version of the 340 Mexico which was intended for the Carrera Panamericana. The use of Weber carburettors helped the 340 achieve 300 hp (224 kW), some 20 more than its Mexico counterpart.
11 examples were made, 4 Pinin Farina Berlinettas, 2 Touring Spyders and 5 Vignale Spyders (designed by Giovanni Michelotti). Some were converted to 375 MM spec.
