The Ferrari 125 S (commonly 125 or 125 Sport) was the first vehicle produced and built by automaker Ferrari of Modena, Italy. Although preceded by Enzo Ferrari's Auto Avio Costruzioni 815 of 1940, the 125 S was the first vehicle to bear the Ferrari name when it debuted on May 11, 1947 at the Piacenza racing circuit. Like the 815, it was a racing sports car, but unlike its Fiat-powered 8-cylinder predecessor, the 125 S featured a V12 engine (the "125"), a trait it shared with most Ferrari cars of the following decades. The 125 S was replaced by the 159 S for 1947.
The 125 S used a steel tube-frame chassis and had a double wishbone suspension with transverse leaf springs in front with a live axle in the rear. Hydraulic power drum brakes were specified front and rear.
The 125 S was powered by Gioacchino Colombo's 1.5 L (1497 cc/91 in³) 60° V12 with a bore/stroke of 55 x 52.5 mm . This engine produced 118 bhp (87 kW) at 6,800 rpm with a compression ratio of 9.5:1. It was a single overhead camshaft design with 2 valves per cylinder and three double-choke Weber 30DCF carburettors.
Enzo Ferrari wanted the 125 S to use a five-speed gearbox as it matched the high revving V12 better than that of a traditional four-speed gearbox.
