The first were the four-door Type 105 entry-level compact executive sports sedans produced from 1962 to 1978; the second are the updated (mainly up-engined) Spider, Sprint, and Sprint Speciale Alfa Giuliettas, and in 2015, Alfa Romeo revived the Giulia name, again for a compact executive car (type 952).

Alfa Romeo was one of the first mainstream manufacturers to put a powerful engine in a light-weight 1 tonne (2,205 lb) four-door car for mass production.

Various configurations of carburetors and tuning produced power outputs from about 80 to about 110 bhp (55 to 75 kW), coupled in most cases to 5-speed manual transmission.

The styling of the three-box four-door sedan was somewhat wanting, with its three main volumes all truly square and boxy, softened only by detailing of the front and bonnet, roofline, and boot.

Using a wind tunnel during development helped designers to find a remarkably aerodynamic shape with a drag coefficient of Cd=0.34,[6][7] particularly low for a saloon of the era.

[10] Other notable interior features of the early models were mottled cloth and vinyl upholstery, a grey, trapezoid instrument panel including a strip speedometer, and a black steering wheel with two ivory-coloured spokes and a chrome half horn ring.

In May 1964 a floor shifter became available (chassis tipo 105.08), to be ordered solely in conjunction with the newly introduced separate front seats.

The floor shifter became standard; the interior received new seats, a new dashboard with triple round instruments (two large ones and the smaller fuel gauge in the centre) in place of the strip speedometer, and new door cards.

[13] On 2 May 1964 the TI Super received international FIA and Italian CSAI homologation for racing, and was then extensively campaigned in the European Touring Car Challenge.

[14] The TI Super's 1,570 cc engine was the same installed on the Giulia Sprint Speciale coupé—though bearing a different type code.

[9][12] Parts contributing to the weight reduction were mesh grilles replacing the inner pair of head lamps, bumpers without overriders, fixed front quarter windows, Plexiglas rear windows, and magnesium alloy wheels with hubcaps, very similar in appearance to the standard steel wheels of the TI.

[16] Contrary to popular belief, the Giulias used by the Italian police forces (the Pantere of the Polizia di Stato and Gazzelle of the Carabinieri) were not tuned TI Supers but rather standard models; early ones were fitted with mesh in place of the inner headlights like the TI Super simply to make the siren mounted behind sound louder.

Visually the 1300 was distinguished by a new grille design housing single instead of twin head lamps, rectangular side repeaters without ornamentation, and all-metal hubcaps.

[11] Inside dashboard and steering wheel came from the TI (though the latter was all-black), there were rubber mats instead of carpets, and several convenience features such as the passenger grab handle and rear ashtrays were omitted.

1,570 cc engine with two double-choke Weber 40DCOE carburettors for a milder, but torquier tune than the TI Super - 98 PS (72 kW; 97 hp) at 5500 rpm.

For 1970, updates included dual-circuit brakes, centre-mounted handbrake lever to replace under-dash "umbrella handle", larger external door handles, and top-hinged pedals (the latter in left hand drive models only; right hand drive continued with bottom-hinged pedals to the end of production).

Other features were the five-speed gearbox, a three-spoke bakelite steering wheel with plastic horn push covering the centre and spokes, and the dashboard initially with strip speedo like that of the TI.

1970 updates included dual-circuit brakes, centre handbrake, larger external doorhandles and top-hinged pedals (on left hand drive cars only), again as applied to the Super for that year.

The car was largely ready for competition and was only planned to be built in limited numbers, and was fitted with racing-style rear-view mirrors, rally lamps, fully adjustable seats, and a limited-slip differential.

With an output of 55 SAE-rated PS (40 kW; 54 hp) at 4,000 rpm and a 138 km/h (86 mph) top speed, the diesel version was the slowest of all Giulias.

Easiest to distinguish from a Giulietta is the Spider (tipo 101.23), which featured a bonnet bulge to clear the slightly taller engine.

This coupé (and rare convertible sister, the Giulia GTC) proceeded to be developed through numerous series with engines from 1.3 up to 2 liters.

The Giulia (952) compact executive car was unveiled on 24 June 2015 at the Museo Storico Alfa Romeo in Arese.
