The origins of the single overhead camshaft engine lay with designs penned by Gioacchino Colombo way back in 1946. With Grand Prix racing in mind the initial displacement was just 1500 cc. In naturally aspirated form the big successes came once the V12 was enlarged to two litres with victories at Le Mans and in the Mille Miglia. This gain in cylinder size was achieved by increasing both the bore and the stroke to 60 mm and 58.8 mm respectively. The bore would grow further, but the stroke remained the same in all future applications of the Colombo engine. The first evolution came in 1950 with the displacement lifted to 2.3 litre on four existing 166 MMs to create the 195 S. The following year the bore was raised to 68 mm for a swept volume of just under 2.6 litre. Fitted to the 212 Export chassis, it was good for a healthy 150 bhp. A total of 27 examples were constructed and during the year a shift in favoured coachbuilder became apparent. All but five of the 166 MMs were bodied by Touring, yet less the Milanese worked on less than half of the 212s. Vignale of Turin handled as many cars as Touring and that trend would continue with the next customer racing Ferrari. In 1951 there also was a slight evolution in the chassis design. The original elliptical-section tubular frame was, for a select few models, replaced by a smaller diameter tubular frame with additional cross braces. Known as the 'Tuboscocca', the new chassis was slightly lighter and more rigid. What remained the same was the very short wheelbase, the double wishbone front suspension with a transverse leaf spring and the live rear axle. Stopping power was provided by drum brakes all around and the engine's horses were transferred to the rear wheels by a five-speed gearbox. Competition from other manufacturers as well as the larger engined Ferrari Works cars had really picked up in the early 1950s. The smaller customer cars were now rarely in contention for overall victories in major events, but still remained highly competitive in local races, particularly in Italy. In 1952 the cylinders were bored out a further 2 mm, raising the displacement to 2.7 litre. Compression was also increased, which helped bump the power to a very impressive 210 bhp figure for the 225 S. All but one of the twenty-one examples built received a Vignale coachwork, fittingly the one exception was a Touring Barchetta. Ferrari's annual increase in engine size ended that year. The company's engineer settled on a bore and stroke of 73 mm and 58.8 mm respectively, which yielded a displacement of 2953 cc. This engine was first fitted to the 1952 Mille Miglia winning 250 S, which would form the basis for a whole range of Ferrari road and racing cars that would win every major race. So the 166 MM, 195 S, 212 Export and 225 S were not only a commercial and competition success for the fledgling company, they also laid the foundation for a very bright future for Ferrari. Featured is a 212 Export that was delivered new to Count Umberto Marzatto in this fabulous two-tone green livery on May 22nd, 1951. He raced the car at various local events including the Coppa d'Oro delle Dolomiti. Its striking paint-scheme earned it features in two major magazines of the day. The best result for this small racing car was a victory in the Trieste-Opicina hillclimb in September of 1951. Count Marzotto held on to his prized possession for another couple years, but eventually decided to sell the 212 Export in 1956. Towards the end of the decade, the Ferrari was exported to the United States. It has remained in American ownership ever since. Like many other 212 Exports, this Vignale Spyder had its engine upgraded from the standard single carburetor setup to a more potent triple Weber setup. The car was also repainted red. In recent years chassis '0090E' was completely restored to its original specification and livery. Since then the two-tone Spyder has been shown at a wide variety of events with great success, including the 2005 Concorso d'Eleganza Villa d'Este where it won the 'Coppa d'Oro.'
