In 1954 Bertone created two prototypes for Alfa Romeo, a spider and a coupé, supplementing the race-winning 1900 series with the aim of extending Alfa Romeo’s competitive dominance beyond the Touring class. Despite not entering mass production, the two cars marked a key milestone in the Milanese automaker’s stylistic evolution: in particular, the lines of the 2000 Sportiva inspired the shape of the iconic Giulietta Sprint.
1950 was a breakthrough year in the history of Alfa Romeo’s industrial transformation, because in that year the new 1900 saloon became the brand’s first car produced on an assembly line, at the Portello plant. Alfa not only stepped up a gear, riding on the wave of Italy's post-war economic revival, but the restructuring of its manufacturing systems radically changed the company's internal organisation.
Alfa concentrated all its economic and human resources on the large-scale production of the “Millenove”, eventually turning its back on the Formula 1 World Championship after having won it twice in a row. However, Alfa Romeo’s commitment to racing did not end there, on the contrary: the 1900 itself soon became “the family car that wins races”. Buoyed by Alfa Romeo’s victories in the Touring class, the company management commissioned several Italian coachbuilders to develop racing cars modelled on the new saloon, for homologation in the GT and Sport classes.
In 1952, Milanese coachbuilder Touring created the futuristic Alfa Romeo 1900 C52, commonly known as the “Disco Volante” (Italian for “Flying Saucer”), which resembled a spaceship with its outlandish contours, wide front wings and low-slung body.
In 1954, Turin-based coachbuilder Bertone was also tasked with developing two prototypes, a spider and a coupé—which became the Alfa Romeo 1900 Sport Spider and the 2000 Sportiva—with a view to producing a limited run of 100 units.
At the heart of both cars was the twin-cam engine of the 1900 with an increased bore which, thanks to the larger cylinder diameter, boosted the displacement right to the limit of the 2000cc class. The 1997cc engine developed 136 HP at 6500 rpm, powered by two large double-barrel carburettors that accompanied the unmistakable cylinder head with twin camshaft. The engine was also equipped with a sophisticated dry sump lubrication system, specifically for competitive use.
The 2000 Sportiva featured a refined tubular steel spaceframe dressed in a light aluminium alloy body, but had the same technical setup as the 1900 production car: longitudinally mounted front engine and rear wheel drive. The independent front suspension was paired with a sophisticated De Dion rear axle with a Watt’s parallelogram linkage, with the drum brakes located at the differential output shaft, instead of near the wheel hubs.
Although they shared identical mechanicals, the spider and coupé were very different in appearance.
