1935 Fiat 508 S “Balilla” Berlinetta Aerodinamica
Italy’s drive toward aerodynamic racing design during the mid-1930s produced some remarkable competition machines, among them the 1935 Fiat 508 S “Balilla” Berlinetta Aerodinamica. Its sleek, contoured bodywork was developed specifically for high-speed endurance events such as the legendary Mille Miglia road race.
Under the teardrop-shaped aluminum body sat a 995-cc inline-four engine producing approximately 36 horsepower, thanks to a revised cylinder head and upgraded carburetor. While modest by modern standards, this output was impressive for its displacement class at the time.
Power was delivered to the rear wheels through a four-speed manual transmission, and the car featured hydraulic brakes (advanced equipment for its era).
The Berlinetta Aerodinamica body style featured a low, flowing profile with partially enclosed rear wheels and a smoothly curved roofline designed to minimize aerodynamic drag. This focus on efficiency over brute power allowed the lightweight Fiat (weighing around 1,500 lb / 680 kg) to sustain high speeds across Italy’s demanding open-road courses.
Only about eleven examples of the 508 S Berlinetta Aerodinamica were built, making surviving cars extremely rare today. The 508 S stands as an early example of how intelligent engineering and aerodynamic innovation enabled smaller-displacement cars to compete successfully against much larger rivals.
