The Ferrari 125 S (commonly 125 or 125 Sport) was a 1.5 litre race car built in 1947 by automakerFerrari in Modena, Italy. It was the company's first vehicle, which only two were made.
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[1] at the Piacenza racing circuit. Like the 815, but unlike its inline-8 predecessor, partly developed from Fiat engine components, the 125 S featured a Ferrari designed and built engine; the ColomboV12 (the "125"), a trait it shared with most Ferrari cars of the following decades. The 125 S was replaced by the 159 S later in 1947.
A five-speed transmission was used in the 125 S as it was better able to exploit the power curves of the high revving V-12 better than a traditional four-speed gearbox.
One of the two Ferrari 125 S examples is located in the "Vault", which is the lowest level of the Petersen Automotive Museum in California. Ref 4.[3]
Chassis 010I
Recently, the chassis with serial number 010I was used in the restoration of a 125 S. It is rumoured that 010I is actually s/n 01C. The story goes that 01C was re-stamped as 010I, and sold to a customer as a new car. Upon taking receipt of the car, the new owner immediately exclaimed, muletto!, which means "Test mule" in Italian, as he could clearly see that his supposedly new car was in fact a used, well-raced car. Ferrari made a new invoice for the car, including a considerable rebate given the car's second-hand nature.
Still in 166 Spyder Corsa configuration, the car was recently sold to Symbolic Motors. Close inspection of the chassis and its serial number led to the discovery of an old stamping that could possibly read 01C. It had been covered by an aluminum plate which bore the serial number 010I. Subsequently, the car was sold to its current owner, who refitted the chassis with a body similar to the factory's 125 S replica, which was built by Michelotto in 1987. The alleged 01C made its public debut at the Pebble Beach Concours d'Elegance, and was entered as a "Ferrari 125 S". The car continues to be the subject of much debate among Ferrari historians and enthusiasts; recent developments indicate that the restamped serial number was in fact a correction and not an alteration.[4][citation needed].
Two weeks later, the 125 S claimed Ferrari's first victory at the Grand Prix of Rome on the Terme di Caracalla Circuit, where it was also driven by Cortese.[5] The car had spun a bearing in practice, and was repaired in the shop of Tino Martinoli, who later came to America with the Ferrari Indy car team.
