The 125 F1 was Ferrari's first Formula One 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, Valerio Colotti and designer, Gioacchino Colombo. Initially the racer was called 125 GPC for Gran Premio Città or Grand Prix Compressore before the Formula One era.[1][2]
Mechanical details
The 125 F1 used a
Worm and sector steering and four-wheel drum brakes
were the norm for the time. The 2,160 mm (85 in) wheelbase was uprated to 2,320 mm (91 in) in the 1949 redesign. The chassis and transmission design was by Valerio Colotti.
The 125 F1 was powered by Colombo's 1.5-litre (1497 cc/91 in³) V12. The engine's name, and the car powered by it, the 125 S sports racer, were derived from the tiny 124.73 cc (7.6 cu in) 55 mm (2.17 in) by 52.5 mm (2.07 in) cylinders. It had a
Maserati 4CLT. Strong driving and a nimble chassis, however, allowed the company to place third in its first outing, at the Italian Grand Prix
on 5 September 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 260–280 PS (191–206 kW; 256–276 hp) gave it five Grand Prix wins.[4] Development continued the following year, but the problematic superchargers were dropped in favor of larger displacement and Lampredi's 275 engine
superseded the original Colombo engine.

The original chassis have been lost (used for
Ferrari 275 F1), but an exact replica with the original Colombo engine currently resides in Museo Ferrari
in Maranello alongside newer Ferrari F1 machines.
