Ferrari 166 FL s / n 011F, here with start no. 16, driven by Juan Manuel Fangio in 4th place at the Grand Prix of Buenos Aires on May 8, 1950 at the Circuito Palermo

The Ferrari 166 FL was a single-seater racing car ( monoposto ), which was built in three copies by Scuderia Ferrari from 1949 to 1952. [1] The term 166 refers to the (rounded) Displacement of a single cylinder, which the former nomenclature of the company corresponded. The abbreviation FL stands for " Formula Libre ". Since the car was mainly developed for racing in South America, it was also known as the 166 C America .


Enzo Ferrari was successful as race director at Alfa Romeo in all major competitions, when he then competed under his own name (and with his own vehicles ) from 1947 , he wanted to continue this success. In order to achieve his ambitious plans, he had his then chief designer Gioachino Colombo design his own V12 engine, although Ferrari's experience with this type of engine was relatively limited. The goal was to equip the entire future range of Ferrari vehicles, including a sports racing car and a Grand Prix monoposto, with this engine. [1]

The Ferrari 166 FL was developed to take part in races in the “Formula Libre Series”, which was extremely popular in South America at the time and had a broad set of rules. When the 166 FL was introduced, the regulations for Formula 2 allowed a maximum displacement of 2 liters; the statutes of the new Formula 1 , which was to begin in 1950, stipulated a maximum displacement of 4.5 liters for naturally aspirated engines and 1.5 liters for charged engines.

For Formula Libre, Ferrari decided to prepare a car whose engine came from the 166 F2, i.e. it was designed for Formula 2 with a displacement of 1995 cm³, and this one with the supercharger , the 125 F1 (which was used for participation in the Formula 1 championship was developed). In this way, a sufficiently powerful and reliable motor was created for this purpose.



The Ferrari 166 FL had a longitudinally installed 60 ° V12 engine with a total displacement of 1995 cm³ that was charged with a Roots compressor . The cylinder head and engine block were made of light metal. The engine had a single overhead camshaft per cylinder bank that controlled two valves per cylinder. The mixture was prepared by three Weber 40 DO3C carburettors, which were connected upstream of the compressor. The ignition was designed simply, the associated system had two magnets. The engine had dry sump lubrication and a multi-plate clutch.

Chassis and suspension

The chassis was made of tubular steel and had a monoposto body.

The suspension of the front wheels had double wishbones and a transverse leaf spring. The rear wheels were attached to a rigid axle with semi-elliptical springs and an anti-roll bar. Both suspensions had hydraulic Houdaille shock absorbers. The 166 FL had drum brakes on all four wheels. The manual transmission was designed for five gears plus reverse. [1]


The maximum output of the engine was 310 hp (231 kW) at 7000 rpm. With a weight of 740 kg, the FL 166 achieved a power-to-weight ratio of 0.42 hp · kg −1 . The top speed of the 166 FL was 310 km / h (193 mph). [1]

Race history

Between 1949 and 1952 the Ferrari 166 FL took part in the “Temporada Argentina” racing series in South America , which was part of the “ Formula Libreseries of events . Here he proved to be very successful despite the tough competition from Alfa Romeo , Maserati and Mercedes .

At the Temporada Argentina the most important victories were: [2] [3] [4] [5] [6]

The Ferrari 166 with the chassis no. 011F was originally built for use in Formula 2 in 1949 . This year from Scuderia Ferrari , with Juan Manuel Fangio at the wheel at the Monza Grand Prix on June 26th, the 166 won a debut victory. [2] After that, the car was (with the support of the Argentine government) of Juan Manuel Fangio purchased and used. The vehicle was repainted in the Argentine racing and national colors blue with a yellow engine cover. Later that season the car was fitted with a Roots supercharger and was used under the designation "FL" in several Formula Libre races in South America by Fangio and Benedicto Campos.[2] After returning to Europe in 1950 drove the car Fangio (now again without a compressor) again in Formula 2, but with little success. [2] In 1951 the 166 (again as "FL" with supercharging) returned to Argentina, and wasquite successfuluntil 1953 with José Froilán González at the steering wheel (3 wins, 3 second places, 1 third place). [2] The car then remained in Argentina until it was discovered by Colin Crabbe in the late 1980s. He imported the car to the UK, where it was extensively restored by Tony Merrick. The well-known collectors Carlos Monteverde and Christopher Cox were among the later owners. In 2003 the ex-Fangio Ferrari 166 FL was acquired by a German private collection.In 2017, the 166 FL was shown at the Goodwood Festival of Speed .
