From the archives - Giorgetto Giugiaro's greatest designs

The fact that he chose a neologism instead of the traditional family name showed that Giugiaro was embarked on a collaborative exercise. The fact that he had a clearly established 'handwriting' from early on showed that ItalDesign was not going to be a traditional carrozzeria, compliant to a manufacturer's whim. The famous Torinese coach-builders - Bertone, Pininfarina, Ghia - all grew out of artisan trades and only later added design and styling to their portfolio.

Still today, Bertone and Pininfarina are involved in producing cars for manufacturers. ItalDesign is different because it only builds prototypes. Giugiaro says he is not crazy about cars, just crazy about styling them. With prototypes, ideas can be turned around in three months; with production, ideas hang around for a long time, as they became locked into an eight-year life cycle.

In the 20 years of astonishing creativity since 1968 when ItalDesign showed the Bizzarrini Manta, Giugiaro has become perhaps the most imitated and innovative of all consultant product designers. His work, both inside and outside of the automotive industry, combines a sensuous appreciation of style and form with a sympathy for technology and the disciplines of production that is rarer than it should be.

Giugiaro's style is so attractive it reverses the trend and is the very opposite of inimitable. Rather, it has become a global language of car design, copied everywhere. Long before he became famous he had enormous esoteric influence in his work on the Alfasud (1971), the Volkswagen Golf (1974) and the Fiat Panda (1980).

All these cars have a crisp, razor-edged elegance and if they are lacking in details or in human factors this is perhaps as much to do with lack of nerve with the manufacturer as with deficiencies of the designer.

Giugiaro is not merely fluent with a Magic Marker. With the Panda he realised to the full the collaborative potential of ItalDesign. The first stage of the presentation included two full-scale models, four alternative solutions for the sides, a buck of the passenger compartment and a comprehensive study of the competition.

When these proposals were approved, Fiat requested ItalDesign to start production studies, build a master model, design provisional tooling and engineer pre-production prototypes.

Within a year 20 rolling chassis had been made. It was in these simple cars that his fresh genius became apparent. Thus, Giugiaro saw a giant manufacturer not as an intimidating client, but rather as an enabling resource - and in this sense Giugiaro has reversed the traditional designer-client role.

It was the oil crisis of 1973 that changed his views about design. Having established a particular model of stylish sports car, he changed to a more practical, more functional one. He said: "I contributed to making that long, low, sleek car fashionable and now it is time to change. I have to eat, you know."

The MegaGamma and its commercial derivative the Fiat Uno are examples of this. While virtually every stylist had in the past concentrated on longer-lower-sleeker-faster, Giugiaro now showed that as much characters art, style, chic and design could be got into a box with the specification of a kitchen as into an exaggerated wedge with superannuated racing hardware.

Giugiaro’s first phase has had its critics, including Ford's Uwe Hahnsen, who said the sharp and angular Golf belonged to the ‘Origami school of design and that the Lotus Esprit only looked dramatic because of its inhuman proportions. But Volkswagen has demonstrated its faith in the original idea by approving the 1983 Mark II, Herbert Schaefer’s warm-up to the original.

The chief characteristic of artistic genius is in its ability to change and adapt, but remain consistent to its goals. Around 1970 ItalDesign was working on cars like the Tapiro, a classic Giugiaro wedge based on a Porsche platform. Yet even with the constraints of the sports car shape you can see a search for new volumes and an ingenious arrangement of spaces all within an elegant and arresting envelope.

After 20 years of cumulative success built on cumulatively successful ideas, Giugiaro is in strange position. Third level manufacturers embrace him and tarnish a carefully image. When he goes in to the Ristorante del Cambio, diners don't whisper in awed hush "that's the man who designed the Hyundai Stellar.” At the same time, the majors, having learned what they can, are staying at home or shopping elsewhere.
