Alfa Romeo Giulietta Type 750/101

The Alfa Romeo Giulietta (Tipo 750 and Tipo 101, meaning "Type 750" and "Type 101") is a family of automobiles made by Italian car manufacturer Alfa Romeo from 1954 until 1965 which included a 2+2 coupé, four-door saloon, estate, spider, Sprint, and Sprint Speciale. The 2+2 was Alfa Romeo's first successful foray into the 1.3-litre class. From 1954 to 1965 a total of 177,690 Giuliettas were made, the great majority in saloon (Berlina), Sprint coupé, or Spider body styles, but also as Sprint Speciale and Sprint Zagato coupés, and the rare Promiscua estate. The Giulietta series was succeeded by the Giulia in 1962.

Giulietta Sprint, Veloce

The first Giulietta to be introduced was the Giulietta Sprint 2+2 coupé at the 1954 Turin Motor Show. Designed by Franco Scaglione at Bertone, it was produced at the coachbuilder's Grugliasco plant near Turin. Owing to overwhelming demand upon the model's introduction, the earliest Giulietta Sprints were hand-built by Alfa Romeo with bodywork made at Bertone and Ghia providing interior and electrical components. Approximately 200–1000 "pre-production" cars were made in this manner, with numerous cosmetic and mechanical differences from the later production cars built at Grugliasco. In 1956, the initially competition-oriented Sprint Veloce version arrived. Weight dropped from 852 to 780 kg (1,878 to 1,720 lb) thanks to various weight-saving efforts, including removing the roll-down windows and mechanisms in favor of sliding, plexiglass units. The Sprint Veloce also did not receive the chromed hubcaps of the standard Sprint. Thanks to two horizontal twin-barrel Weber 40 DCOE3 carburettors, an electric Bendix fuel pump, and a raised compression ratio of 9.5:1, power climbed to 90 PS CUNA (66 kW; 89 bhp) at 6,500 rpm with torque of 12.0 kg⋅m (118 N⋅m; 87 lb⋅ft) at 4,500 rpm. Alfa Romeo also issued an SAE gross rating of 104 PS (76 kW; 103 bhp) which may be seen in period brochures. The Sprint Veloce did enter competitions, claiming the first three positions in its class at the 1956 Mille Miglia, for instance, but it was frequently bought as a small gran turismo and Alfa accordingly introduced a Confortevole ("comfortable") version, featuring wind-down plexiglass door windows in aluminium frames, chromed hubcaps, and different, larger headlamps. Around 200 Confortevoles were built. Sometime in late 1956, after the Berlina T.I. and Sprint Veloce had been introduced, the regul

Giulietta Berlina

A year later, at the Turin Motor Show in April 1955, the Sprint was joined by the 4-door Berlina saloon which had always been intended as the main offering. This had an engine with a much gentler tune, lower compression ratio (7.5:1) and one single-barrel carburettor, to provide better fuel economy and drivability. Max power was 50 PS CUNA (37 kW; 49 bhp) at 5,200 rpm (53 PS according to some sources). In late summer 1957 the Berlina T.I. (Turismo Internazionale) appeared, using an engine very similar to that of the Giulietta Sprint. Thanks to a Solex, twin-barrel carburettor and a slight bump in compression ratio to 8.0:1, the maximum power was brought up to 65 PS CUNA (48 kW; 64 bhp) at 5,500 rpm. The T.I. also received minor cosmetic changes to the hood, the dial lights and rear lamps. To streamline production and to lower manufacturing costs, the Giulietta Berlina (and sporting variants as well) underwent a series of gradual minor changes to the bodywork from 1957 until 1959. The engine block castings were also changed from sand casting to die casting, prior to the introduction of the 1570 cc Giulia engine. The carburettors were also subject to revision and in 1958 a new, stronger gearbox with Porsche-type syncromesh was introduced. Still a four-speed, it included provisions for adding a fifth. Carrozzeria Colli also made a Giulietta station wagon variant called Giulietta Promiscua. Ninety-one examples of this version were built. Carrozzeria Boneschi also made a few station wagon examples called Weekendina. 1959 restyling. A new version of the Giulietta Berlina debuted at the Frankfurt Motor Show in 1959. Mechanical changes were limited to shifting the fuel pump from the cylinder head to a lower position below the distributor, and moving the previously exposed fuel

Giulietta Spider

Max Hoffman, Alfa Romeo's American East Coast importer requested a convertible version of the Giulietta Sprint, committing to a significant purchase (2,600 Giuliettas overall). Alfa Romeo charged Bertone and Pinin Farina with developing competing designs, with the more sober-looking Pinin Farina design winning out. Bertone's dramatic design, penned by Franco Scaglione, built on the design of the earlier 2000 Sportiva Coupé, with a sharp nose with covered headlights and prominent tailfins. The front design presaged that of the later Duetto. While Hoffman favored the Pinin Farina option, he did purchase the Bertone prototype for his own personal use. At the October 1955 Paris Salon, the open two-seat Giulietta Spider made its official debut, using the Sprint's 65 PS (48 kW; 64 hp) engine and a shortened, 2,200 mm (86.6 in) wheelbase. Hoffman received the first 600 examples built, meaning that the Spider was available to American buyers for quite some time before Italians were able to get their hands on one. Early production examples were quite different from later cars. While the prototype had a panoramic windshield à la the Lancia Aurelia B24 Spider, early production cars had a simpler, curved front windshield along with roll-down windows but no quarter lights. The Paris Show car also had conical bumper guards at the front, and differing instrumentation which carried over to pre-series cars, most of which also had column-mounted shifters. On 750-series Spiders, the dashboard was made from sheet metal (with a thin black vinyl pad on top) and the glove compartment had no door. The steering wheel was a two-spoke affair with a horn ring. In 1957, doors with fixed quarter lights were introduced, but Alfa Romeo still installed the old style doors on occasion until 1959. The Sp

Specifications

The Alfa Romeo Giulietta used unibody construction and a front-engine, rear-wheel-drive layout. Front suspension was by control arms, with coaxial coil springs and hydraulic dampers. At the rear there was a solid axle on coil springs and hydraulic dampers. The axle was located by a longitudinal link on each side, and by a wishbone-shaped arm linking the top of the aluminium differential housing to the chassis. All Giuliettas (save for the last SZ examples) had hydraulic drum brakes on all four corners. Engines. The Giulietta used an Alfa Romeo Twin Cam straight-four of 1290 cc, with an aluminium alloy engine block and cast iron inserted sleeves. Bore and stroke measured 74.0 mm (2.91 in) and 75.0 mm (2.95 in). The aluminium alloy cylinder head was of a crossflow design and featured hemispherical combustion chambers. The double overhead camshafts were driven by two timing chains, and acted on two valves per cylinder, angled 80°. Power figures vary somewhat depending on source and ratings, with Alfa Romeo typically using Italian CUNA but also SAE Gross at times.
