  • Ingenuity, advanced materials, and styling that marries technological innovation and creativity: these are the ingredients of the Tipo 33’s design.
  • Rooted in Alfa Romeo’s competitive spirit, two “non-identical twins” were conceptualized on this racing technology:the 33 Stradale and the Carabo.
  • Designed by Franco Scaglione, the 33 Stradale is a masterful synthesis of technical creative daring: where innovation in style blends with the quest for aerodynamics and functionality.
  • Bertone’s Marcello Gandini designed the Carabo pointed to the future, with fine attention to colour and paintwork that would continue to be explored in the Montreal.
The car as a sign of the times
Headlights for “eyes”, the front grille for a “mouth”, the front for its “face” – and, of course, the car its “body”, with “shoulders” and “hips” traced by the wheel arches. These descriptors are still used today. But how did they come about, and why?

The first cars were literally “horseless carriages”, with no specific embellishments. As car design evolved, various “coachbuilders” became prominent, particularly from the 1930s onwards. They beat the sheet metal into shape by hand, directly onto a wooden frame, creating genuinely unique models with rounded, sensual lines. As industrial production evolved, the designs tended to simplify, if only because the pressing equipment of the time couldn’t stamp out such voluptuous forms.

At one point, in the late 1960s, the two stylistic inspirations noticeably diverged. The difference between those curvy cars with hips and faces and what was considered to be the “car of tomorrow” is easily seen in the differences between the 33 Stradale and Carabo – two Alfa Romeo models developed from the same technical base.

Drawing on the same platform
The 33 Stradale and the Carabo could not look more different. One all nerves and sinews, like an athlete in the midst of competition; the other, all straight lines and angles, aimed at grasping the essence of mobility and pushing it forward into the future. So much more than two interpretations, these are two different worlds.

The shared technical basis of these two cars was the culmination of 50 years’ of racing experience at Alfa Romeo. Ingenuity, advanced materials, and styling that marries technological innovation and creativity: these are the ingredients of the Tipo 33’s design

The desire to compete
All this stems from the desire to compete, one that has never waned at Alfa Romeo. In 1964, Giuseppe Luraghi – the then president of Alfa Romeo – felt it was time for an official return to motorsport. To re-establish the racing team, he acquired Autodelta, an Udine company that was already a privileged partner in the production of the TZ. Along with Autodelta, Carlo Chiti – who worked at Portello from 1952 to 1957 – also returned to Alfa Romeo, taking on the role of head of the official works racing team.

In the same year, the 33 project began. Luraghi asked his team for a car that could compete in the most popular form of motorsport at the time: the World Sportscar Championship and the time trials were at the height of public and media attention.

Autodelta
In the mid-1960s, Autodelta relocated to Settimo Milanese – closer to the Alfa Romeo plant, but most of all to the Balocco test track.

The first Tipo 33 frame designed by Alfa Romeo arrived at the Autodelta workshops in 1965. It featured an asymmetrical "H" tubular structure, made of aluminium alloy, with integral fuel tanks. A magnesium structure supported the front suspension, radiators, steering, and pedals while the engine and gearbox was mid-mounted longitudinally in the rear. The fiberglass bodywork limited the total mass of the car to 600 kg – the minimum regulatory weight. Once again, lightness was Alfa Romeo's secret weapon.

Victory in the 1975 and 1977 World Championship for Makes
The first 33 to race was immediately nicknamed “Periscopica”, for the air intake that popped out above the roll bar submarine-style. The time trial at Fléron, near Liège in Belgium, was chosen for its debut with Autodelta’s chief tester, Teodoro Zeccoli behind the wheel. After years of meticulous preparation, the 33 entered the world of competitive motorsport on March 12, 1967. It was immediately victorious and would go on to win some of the most prestigious races and the 1975 and 1977 World Championship for Makes. The 33 truly was a dominant motorsport force.

The Florentine aristocrat who wanted to be a designer
When Alfa Romeo decided to produce the 33 in very small numbers for private individuals, it needed a new look to bring its sporty character to the roads. The project was entrusted to Franco Scaglione.

Born in Florence into an aristocratic family, Scaglione studied aeronautical engineering until he was conscripted into the army. He then set off for the Libyan front and was taken prisoner in Tobruk. He returned to Italy in late 1946. Determined not to resume his studies, he chose to become a car designer: first with Pinin Farina, then with Bertone, and later working freelance.

Scaglione put all his technical expertise and creative daring into the design of the 33 Stradale, resulting in a masterpiece where innovation in style blends with the quest for aerodynamics and functionality.

The 33 Stradale
The bonnet of the 33 Stradale opens fully to improve access to the mechanical components. For the first time on a “street-legal” car, its “dihedral” doors allowed easier access to the low-slung sportscar that was no more than one meter high. The only differences from the track version were the extension of the wheelbase by 10 centimetres, and a steel frame rather than an aluminum one. The engine was the same as the Tipo 33, made entirely of aluminium and magnesium alloys, with indirect mechanical injection and dry-sump lubrication. With twin overhead cams per bank, two valves per cylinder and dual ignition, its 230 hp mean the lightweight Alfa could reach a maximum speed of 260 km/h, with a 0 to 100 km/h time of 5.5 seconds.

The premiere event in Monza
The car was officially launched at the 1967 Turin Motor Show but had been unveiled a few weeks earlier to an enthusiastic audience of experts. On September 10, 1967, the Italian Grand Prix – the ninth round of the Formula One World Drivers’ Championship – was held in Monza. That GP went down in history for Jim Clark's epic comeback against Jack Brabham – and for the debut of one of the most beautiful sports cars ever made. At launch, the 33 Stradale was the most expensive sports car on the market, then selling for almost 10 million Italian lire, compared to 6-7 million for its most prestigious rivals. Only 12 cars were produced with Scaglione bodywork. Its buyers were making the investment of their lives: they are virtually priceless today.

The car-spaceship
A “dream car” was presented at the 1968 Paris Motor Show, representing the evolution of this radical idea: the Carabo, designed for Bertone by Marcello Gandini, then only 30 years old.

A non-identical twin: the Carabo
The Carabo was based on the mechanics of the 33 Stradale, used at the time by other designers for one-offs such as Giorgetto Giugiaro's Iguana, the 33 Special Coupé, Pininfarina's Cuneo, and Bertone's Navajo. The height was the same, but the rounded lines had disappeared completely. Everything in the Carabo is clear-cut, from the wedge design to its “scissor” doors. The name Carabo was inspired by the Carabus auratus, a brightly metallic-coloured beetle. The same hues are used for the car's body: luminescent green with orange details. From then on, Alfa Romeo began to explore extravagant colours and special paintwork techniques, to highlight the brand’s uniqueness even more, a theme that would continue with the Montreal.

The Montreal
In 1967, nations from across the world brought their best technical and scientific achievements to the International and Universal Exposition in Montreal. Alfa Romeo was asked to create a technological symbol for the Expo – a model to represent “the highest aspiration of modern man in terms of cars”. Satta Puliga and Busso requested assistance from Bertone, which tasked Gandini with designing the bodywork and interiors. The result was a resounding success. North American visitors resonated with the car’s daring elegance and in the wake of this public demand, a production model was developed and presented at the Geneva Motor Show in 1970. Unlike the original concept, this Montreal had a V8 engine based on the Tipo 33, raised to 2.6-litre capacity and limited to 200 hp. The model boasted an extraordinary range of colours, both pastel and metallic: from green (previously used in the show car for the Expo) to silver, and from orange to gold. This exploration of vivid colours would become an Alfa Romeo tradition and reflected in today’s new colour palette: Red Villa d'Este, Ocher GT Junior and Montreal Green. These hues are inspired by the 110-year history of the Brand, and are dedicated to some of its most glorious models.
