came with the same crash gearbox as the other cars, but the engine was fed by a special carburetor, which with its raised compression ratio of 7:1 gave rise to a maximum output listed as at 4,000 rpm. The final drive ratio was also altered, and top speed went up to 110 km/h (69 mph). Fiat 508s with this body type were assembled by Fiat in Italy, and were also included in the production schedules of Fiat affiliates/subsidiaries Germany, France and Czechoslovakia. Various small scale enhanced versions appeared, including the Fiat 508S, known as the "Fiat 508 Coppa d’Oro" ("Gold Cup"), especially prized by collectors 75 years later. The "Spider Sport" received the transmission upgrade to 4 speeds in 1934 together with a special overhead valves (at a time when other 508 variants still came with a side valve engine) and other technical enhancements which pushed the power up to . The most sporting versions advertised their performance aspirations with a more steeply tapered Tail section Coupé Launched in 1935, the "Coupé" bodied 508 (also sometimes known as the "Berlinetta Mille Miglia") shared its mechanical elements, including the more powerful 108CS engine, with the "Spider Sport". The body was a 2-seater aerodynamic Berlinetta, intended for competition use in colder climates such as those encountered in Northern Italy during the "Mille Miglia" (then run in late Winter). The Coupé may have been warmer in cold weather than the Spider Sport, but it was also heavier: competition success proved elusive. Van A commercial version of the Balilla was offered, both as a panel van or as a small flat-bed truck, with a 350 kg load capacity, based initially on the 3-speed 508A and later on the 4-speed 508B. Foreign assembly Poland As well as being assembled at Turin in Italy, three successive versions of the car were produced in Poland where it was branded as the "Polski-Fiat 508" and priced at 5,400 Zł. The arrangement was based on an agreement dated 21 September 1932 and provided for the assembly of the car by Centralne Warsztaty Samochodowe in Warsaw. Assembly progressed to full-scale production in 1935 and the 508 became the country's top selling passenger car for a period during the 1930s. There were few paved roads in Poland at this time, and both the chassis and the axles of the car were strengthened, and the suspension was modified, in order to cope
