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. With the exception of a single Touring Barchetta, all 2.7-litre engined cars received coachwork from Vignale.
Ferrari's annual increase in engine size ended that year. The company's engineers 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. << Prev Page 2 of 2
