The 125 F1 Ferrari's first Formula 1 car. It shared its engine with the 125 S sports racer which preceded it by a year, but was developed at the same time by Enzo Ferrari and famed designer, Gioacchino Colombo.
The 125 F1 used a supercharged 1.5 L V12 engine and sported a steel tube-frame chassis with longitudinal and cross members. It had a double wishbone suspension with a transverse leaf spring in front and a torsion bar in the rear which was upgraded to a de Dion tube for 1950. Worm and sector steering and four-wheel drum brakes were the norm for the time. The 2160 mm (85 in) wheelbase was uprated to 2320 mm (91 in) in the 1949 redesign.
The 125 F1 was powered by Gioacchino Colombo's 1.5 L (1497 cc/91 in³) 60° V12. It had a single overhead camshaft on each bank of cylinders with a 60° angle between the two banks. The endine had two valves per cylinder fed through one Weber 40DOC3 or 50WCF carburettor. With just a 6.5:1 compression ratio, the supercharged engine still produced 230 hp (172 kW) at 7000 rpm. However, the Roots-type single-stage supercharger was incapable of producing the high-end power required to compete with the strong eight-cylinder Alfa Romeo 158 and four-cylinder Maserati 4CLT. Strong driving and a nimble chassis, however, allowed the company to place third in its first outing, at the Valentino Grand Prix on September 5, 1948, and the company persevered in racing.
For 1949, the engine was further modified with dual overhead camshafts (though still two valves per cylinder) and a two-stage supercharger. This combination gave the car better top-end performance and the resulting 280 hp (209 kW) gave it five Grand Prix wins. Development continued the following year, but the problematic superchargers were dropped in favor of larger displacement and Lampredi's 275 engine superceded the original Ferrari engine.
Racing
The 125 F1 debuted at the Valentino Grand Prix on September 5, 1948. Three cars were fielded, with drivers Prince Bira of Siam, Nino Farina, and Raymond Sommer who placed third in the race.
