The Ferrari 340 Mexico was a Ferrari sports racing car which was intended for the 1952 Carrera Panamericana. It used 4.1 L Lampredi V12 engine producing around 280 PS (206 kW) at 6600 rpm, for a maximum speed of 280 km/h. Just 4 were made in 1952, 3 Vignale Berlinettas and 1 Vignale Spyder; all designed by Giovanni Michelotti. Mexico used a 2,600 mm (102.4 in) wheelbase. Chinetti and Lucas finished the race at third place in berlinetta.
The Ferrari 340 MM was an evolution of the 340 Mexico with shorter, 2,500 mm (98.4 in), wheelbase. MM used the same 4.1 L Lampredi V12 with similar three Weber 40DCF carburettors that helped the 340 achieve 280 PS (206 kW) at 6600 rpm and a maximum speed of 282 km/h. 10 examples were made, 4 Pinin Farina Berlinettas, 2 Touring Spyders and 4 Vignale Spyders (designed by Giovanni Michelotti). A total of four were converted to 375 MM spec. Giannino Marzotto won Mille Miglia 1953 edition in Vignale spider, setting a new average speed record for the race; with other 340 MM finishing fourth. Two more 340 MMs were entered that year in Touring barchetta guise but did not finish.
