Ferrari 250 MM
The Ferrari 250 MM was a sports racing car produced by Ferrari from 1952 to 1954. After the initial racing successes of the 3.0-litre Colombo V12 engine, introduced in the 250 S one-off, Ferrari produced a serial racing model. It is best recognisable for the distinctive closed berlinetta bodywork by Pinin Farina. The "MM" in its name stood for the Mille Miglia race.
The 250 MM was the second of the ubiquitous 3.0-litre Colombo-engined Ferraris. The engine was derived from the 250 S with increased power, due to a different carburettors setup. The whole car could be seen as an incremental evolution over its predecessor. Chassis numbers for the first time had "MM" in their suffix, and used an even, race car sequence.
Two body styles were available, each from a different coachbuilder. Pinin Farina designed an innovative closed berlinetta, which ushered in a whole new era in automotive design. It also served as a basis for future competition berlinetta models produced by Ferrari. Pinin Farina created in total eighteen 250 MMs with a berlinetta body. An open barchetta body was offered by Vignale and introduced in three series. Every example differed in slight detail from each other. Early series cars had open headlights and a small air vent in the middle of the bonnet. Later cars differed by having recessed and covered headlamps, a closed bonnet bulge, a triangular cutaways in the rear fenders and a lower door line. In total, twelve open spyders were made. Chief designer at Vignale was Giovanni Michelotti who penned all those designs.
The first 250 MM, in a spyder form, was presented in 1952 at the Paris Motor Show. The first berlinetta was also shown in Paris, but a year later.
A single berlinetta by Vignale, created in 1954, was owned at one point by Peter Monteverdi. In 1956 he had paid 10,000 Swiss francs for it and also traded in his Porsche 356. Its distinctive feature were the triple portholes on the bottom of the front fenders.
One particular example, initially s/n 0352MM, was restamped as 0239EU after a crashed 212 Inter, that was entered in the 1952 Carrera Panamericana. His owner, Efrain Ruiz Echeverria, traded it in for a new car that was renumbered in the factory to avoid import duty. By 1953 Ruiz Echeverria could enter another edition of the Mexican marathon. The car was for sale in 2011. Offered by Talacrest it was bought by Nick Mason.
Some examples, like the s/n 0266MM and 0356MM, used "166MM/53" type chassis but with a 3.0-litre, 250 MM-sourced engine. A single example of the Ferrari 340 MM Pinin Farina Berlinetta, that was raced by "Pagnibon", was downgraded to a 250 MM-specification for Andre Vanoni.
The engine, mounted longitudinally in the front, was a 60° Colombo V12. The total capacity of 2,953.21 cc (3.0 L; 180.2 cu in) was achieved thanks to 73 by 58.8 mm (2.9 by 2.3 in) of bore and stroke. A 9:1 compression ratio with three Weber 36IF/4C carburettors helped produce 240 PS (177 kW; 237 hp) at 7200 rpm. The engine had single overhead camshaft per cylinder bank, actuating two valves per cylinder. It also used a single spark plug per cylinder with two coils. The 250 MM had a new multi-plate clutch (the 250 S had only a single plate). A wet sump lubrication system was also inherited.
