 cars for Fiat. In 1933 when work commenced on the Fiat 500, the director of the aero-engine division was Antonio Fessia. He had sufficient confidence to entrust the design of all the mechanical components of the car including the chassis to Giacosa. Giacosa was engineering manager at Fiat by 1937 and he had become director of the engineering division of Fiat by 1950. He retired from his full time position with Fiat in 1970, but retained close association with the company courtesy of a position which translates as "Consulting Engineer to Fiat's Presidency and General Management and a Company's Ambassador with National and International Organizations". Following his retirement he wrote several volumes of memoirs concerning his professional life.

Giacosa's next design was the Fiat 508C. A completely new car to replace the 508 Balilla, the 508C or as it became known as the "Millecento", had a 1100 cc short stroke engine, with overhead valve

It was with a 508C chassis that as engineering manager Dante Giacosa led a team that developed the Fiat 508CMM a streamlined coupe. Fiat used the car to win the 1100 cc class in the Mille Miglia

 or 'super-light' construction technique. The Fiat 1100 cc engine that was fitted to the car was tuned to produce 60 bhp. A maximum speed of 175 km/h was claimed. A batch of twenty cars was laid down in 1946 and the cars were raced successfully throughout the rest of the 1940s.

Giacosa did the initial design work on the next Cisitalia model, a two-seat sports car, the Project 202. Again he used a multi tube space frame chassis. The design being an adaptation of the single seat model. The prototype was fitted with a coupe body similar to the Fiat 508CMM. Before series production commenced, he passed over responsibility for the design to Giovanni Savonuzzi.

Though Dante Giacosa had become director of the engineering division of Fiat, that didn't mean that he could follow his own inclinations regarding the design of any new cars. The Fiat sales department had an overriding influence on new the model produced. Therefore Giacosa may be excused that his next design the Fiat 1400

 of 1950 was only a qualified success. Fiat wanted to produce a car that satisfied the needs of countries with a poor road system that had previously been supplied by American manufacturers before their cars had become bloated. They wanted a car with good stability, good visibility, and room for six people and their luggage, a speed of 120 km/h and a fuel consumption of 10 km/l.

. Despite Giacosa's best efforts they got a car that nether one thing or another. Only one hundred and twenty thousand examples were produced in eight years.

His next light car design was the 1100-103; this model perpetuated the name Millecento previously given to the 508C. This Millecento was a compact unitary construction saloon fitted with wishbones and coil spring

 inline four-cylinder engine of 1089 cc, that at first produced 33 bhp rising to 44 bhp but much more when tuned. Features that would unfamiliar to us today were the steering column change for the four-speed gearbox, and the transmission handbrake. Through a series of models culminating with the 1100R, (The 1100D had a 1221 cc engine.) the Millecento was in production until 1970 and one and three quarter million examples had been produced.

Next Giacosa and his team designed a replacement for the Fiat Topolino

. The last version of the 500C had been discontinued the previous year 1954. The 600 was a totally new car, and for Fiat a new layout with the engine at the rear as well as unitary construction. When the 600 were introduced in 1955, rear engine cars had been produced for well over a decade and their advantages and disadvantages [were] by then well known. Giacosa used the advantages to produce a four-seat car, although with limited luggage space, that had a reasonable performance from an engine of only 633 cc, due to its low weight of 585 kg and also compact dimensions. Capable of almost 100 km/h (62 mph) and returning a fuel consumption of 16 to 20 km/l and the ability to cruise at 80 km/h (50 mph). He overcame the stability problems associated with other rear-engined designs by identifying that the problem was not the weight distribution of the cars, but the simple swing axle rear suspension used in those designs. His answer was to use a semi-trailing arm type of rear suspension that eliminated the large change in the camber of the rear wheels that was inherent with the simple swing axle suspension system.

The mini people carrier may seem to be a concept of the 21st century, that is not so. Within a year of the launch of the 600 a six-seat version was in production, the Multipla. By replacing the transverse leaf spring used in the front suspension by upper links and coil springs, the mechanic components of the 600 were utilised in a forward control unitary body, removing the front luggage compartment and any trace of crumple zone

 (similar to the VW Type 2 Kombi/Bus, but considerably smaller), therefore needing only a small increase in wheelbase to accommodate three rows of seats. Over seventy six thousand of this first version of the Multipla were produced by 1963. The 600 was replaced by the 600D in 1960. The engine size was increased to 767 cc, with a maximum speed up to 110 km/h. Production ceased in Turin

Giacosa's next rear engine car for Fiat was the Nuova 500 of 1957, with a similar layout to the 600, but with a two-cylinder air-cooled engine instead of the water-cooled inline four-cylinder unit, and an unsynchronised 4-speed gearbox (the shortcomings of which being blunted by its own low inertial mass, plus that of the engine and entire vehicle), a layout kept for the entire lifespan of the model. Being a two/plus/two-seat car, it was the true replacement for the "Topolino", at the bottom of the Fiat range. With a wheelbase fractionally over six feet and a length under nine feet, it was also a lightweight weighing less than five hundred kilograms. The 479 cc engines in the early production cars were so underpowered with only 13 bhp that they were recalled and an uprated engine that produced 16.5 bhp was fitted. The final 500-F of 1965 had a 499 cc engine producing 18 bhp, sufficient to get to 110 km/h and a fuel consumption 20 km/l. In 1960 Fiat introduced the "Giardiniera", a 499 cc station wagon with a similar inline twin-cylinder engine as the "500", but with cylinder horizontal. The engine was located under the floor at the rear of the car. With a slight increase in wheelbase and the weight increased to 570 kg, it was newer a four-seat car with a luggage area over the engine.
