Car with Alfa Romeo Certificate of Origin which certifies its originality
The US-based Alfa Romeo importer, “Max Hoffman” of New York, asked Alfa Romeo to produce a “spider” version of the Alfa Romeo Giulietta Sprint and immediately committed to buy 2,500 pieces to be offered in the North American market, always very receptive for the “open” versions of sports cars. In 1954 Rudolf Hruska contacted the Bertone and Pininfarina body shops, entrusting them with two chassis each, in order to execute their proposals for the future “Giulietta Spider”. Nuccio Bertone presented two prototypes, different in some small details, made to a design by Franco Scaglione, while the proposal by Pininfarina had been entrusted to the pencil of Franco Martinengo.
Bertone’s proposal, with a markedly sporty appearance, had been realized maintaining the striking silhouette of the “2000 Sportiva” concept, with a very profiled muzzle, carinated headlights and characterized by rear fins. The Pininfarina proposal, on the other hand, was inspired by the Lancia Aurelia B24, with a more sober stylistic approach and linked to the Italian tradition for cabriolet cars. On the latter fell the choice to start production of the new spider Equipped with more accurate finishes than the “Sprint” version, the “Giulietta Spider” was also a very successful model. The first prototypes were set up with an America-style panoramic windscreen and sliding side windows that hooked to the hood; subsequently, for the series versions, a more conventional flat windshield was adopted and the side windows descending in crystal.
The evolution of the cars in the early 60s led Alfa Romeo to increase the capacity and performance of the Giulietta Spider. The Giulia 1600 Spider “101.23 series” was born as the evolution from the Giulietta Spider “101.03 series”. The cars are almost identical from the aesthetic point of view, except for the existence of a false air intake on the hood of the Giulia necessary to house the new engine and for the word “1600” on the tail of the latter. There are other differences in the interior, more precisely in the characteristics of the steering wheel, now in three races and in the graphics of the instruments, except in the first examples in which they were identical to those of the previous model.
Starting from the spring of 1964, this model was also marketed in a Veloce version, called “101.18 series”, which fitted a more powerful engine capable of offering greater performance. This latest version represents the maximum performance development of the “Giulietta Spider” and “Giulia Spider” series.
The engine was a four-cylinder in the front and a longitudinal line of 1570 cm³ of cylinder capacity. The bore and stroke were 78 mm and 82 mm respectively, while the compression ratio was 9: 1. The base and the headboard were manufactured in light alloy. The maximum power delivered by the engine was 92 hp at 6,200 rpm for the “Normal” version, while it reached 112 hp at 6,500 rpm for the “Fast”.
The distribution consisted of two valves per cylinder that were moved by a double overhead camshaft. The “Normal” version was powered by a Solex carburettor and a 32 PAIA 5 model, while for the “Veloce” version there were two carburettors. The cooling system was water circulating.
The transmission consisted of a synchronized five-speed manual gearbox that had a final reduction ratio of 8/41.
The first 5,600 cars produced mounted three-drum drum brakes on all four wheels. Later on the front brakes were adopted during 1963. The front suspensions were independent and they had installed an anti-roll bar, while in the rear ones there was a rigid bridge.
The maximum speed reached by the model was 172 km / h.
In May 1964 the “Veloce” version was presented which fitted two dual-body carburettors which increased the power to 112 hp at 6,500 rpm and a top speed of over 180 km / h.
