Prima Ferrari realizzata a Maranello, con la

scelta di Enzo Ferrari di avere un motore V12,

e progetto di Gioachino Colombo, il motore 12

cilindri a V, unico nelle corse dell'epoca, ha

permesso un immediato successo a Ferrari

e originato vetture Sport, GT stradali e

monoposto di F1 e F2. L'auto esposta,

ricostruita, è identica a quella andata perduta

che ha permesso al Cavallino di vincere la

prima corsa, il GP Roma del 25 maggio 1947.

La carrozzeria fu realizzata dai "battilastra"

dell'azienda ispirati da uno schizzo di

Gioachino Colombo

 

Enzo Ferrari decided that the first Ferrari built

at Maranello, designed by Gioachino Colombo,

was to be powered by a V12 engine. The V12

engine, which was unique in racing at the time,

brought immediate success to Ferrari, and gave

rise to a succession of Sport, GT and road cars,

as well as single seat F1 and F2 racers. The car

exhibited is an identical reproduction of the car

- which has since been lost - with which Ferrari

won its first race at the Rome GP on 25th May

1947. The body was crafted by the company's

own panel beaters, who took inspiration from a

sketch by Gioachino Colombo

Stessa famigliaFerrari 125 F1

La 125 S o 125 Sport fu la prima autovettura da competizione costruita, in soli due esemplari, dalla neonata Ferrari. Fu collaudata e guidata da Franco Cortese, primo pilota Ferrari, in ordine cronologico.[1] Si tratta di una barchetta a ruote coperte, dalla cui meccanica venne ricavata, l'anno successivo, la Ferrari 125 F1 destinata alle competizioni automobilistiche per le vetture a ruote scoperte.

 

Oltre ad essere la prima con il marchio Ferrari fu anche l'ultima vettura a scendere in pista con il vecchio colore "rosso corsa Alfa Romeo" che aveva sempre caratterizzato le macchine della Scuderia Ferrari. In seguito, la scuderia di Maranello adottò stabilmente per le sue vetture il "rosso corsa FIAT".

 

L'esordio della Ferrari 125 avvenne al circuito di Piacenza l'11 maggio 1947, l'unica vettura che partecipò alla gara, guidata da Franco Cortese, si ritirò per un'avaria alla pompa di alimentazione a tre giri dalla fine, mentre stava rimontando.[2]

 

I due esemplari costruiti, con alla guida Nuvolari e Cortese, furono schierati in gara sul Circuito di Parma, il 13 luglio 1947. Vinse Nuvolari, seguito da Cortese a meno di 10", alla media di 93,733 km/h.

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.

Overview[edit]

Chassis[edit]

The 125 S used a steel tube-frame chassis[1] 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.

 

Engine[edit]

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.

 

Transmission[edit]

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.

Both of the two 125 S cars built in 1947 were dismantled, and their parts are thought to have been re-used in production of the 159 or 166 models.

 

Chassis 010I[edit]

Recently, the chassis with serial number 010I was used in the restoration of a 125 S. It is rumored 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.[citation needed]

 

Racing[edit]

The 125 S debuted at the Circuito di Piacenza, driven by Franco Cortese,[2] but was unable to finish the race, despite a favorable showing against the strong Maserati 6CS 1500s.

 

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.[2] 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.

 

The 125 S won six of its fourteen races in 1947, though drivers Clemente Biondetti and Giuseppe Navone were unable to win the 1947 Mille Miglia in it.

125C (125 Sport, 1947)[Bearbeiten]

Anfang 1947 lancierte Ferrari als erstes Modell des jungen Unternehmens den 125C (für Competizione, auch 125 Sport genannt) mit einem von dem früheren Alfa Romeo-Ingenieur Gioacchino Colombo konstruierten V12-Motor von 1,5 Litern Hubraum, offiziell 54–87 kW (72–118 PS) stark, mit einem Gabelwinkel von 60°, einer obenliegenden Nockenwelle pro Zylinderbank und Einfachzündung. Der Radstand betrug 2420 mm, an der Vorderachse kamen Doppelquerlenker und eine Querblattfeder zum Einsatz, hinten eine Starrachse mit halbelliptischen Blattfedern.

 

Gebaut wurden zwei Exemplare, eines mit breiter Spider-Karosserie der Carrozzeria Touring, das andere mit freistehenden Kotflügeln und schmaler Rennsportkarosserie. Beide Wagen existieren heute nicht mehr, allerdings baute Ferrari in den späten 1980er-Jahren eine Replika.

 

Die Autos nahmen 1947 an einigen Rennen teil, ohne dabei besondere Erfolge feiern zu können. Zur Leistungserhöhung nahm das Werk daraufhin eine Hubraumerhöhung vor und nannte das Nachfolgemodell Ferrari 159.

 

125GP (1948/49)[Bearbeiten]

Im September 1948 fand der 1,5-Liter-Motor aus dem 125C in modifizierter Form erneut Verwendung. Er trieb den Monoposto 125GP an, der an den Vorläuferrennen der ab 1950 ausgetragenen Formel 1 teilnahm. Mit einem Roots-Kompressor ausgerüstet, leistete die Maschine hier 169 kW(230 PS). Der Einsitzer ruhte auf einem Längsträgerrahmen mit einem Radstand von 2160 mm und besaß eine hintere Pendelachse mit Torsionsstäben oder Querblattfeder.

 

125F1 (1949/50)[Bearbeiten]

Beim 125F1 handelte es sich um eine modifizierte Version des 125GP mit zwei obenliegenden Nockenwellen pro Zylinderbank und längerem Radstand von 2380 mm, vorgestellt vor dem Großen Preis von Italien in Monza im September 1949. In dieser Form leistete der Motor 191 kW (260 PS).
