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.
