Alfa Romeo 105 Series: Restoration and Bodywork

The Alfa Romeo Giulia 105 Series was introduced in 1962 and was intended to replace the Giulia 101 Series saloons, coupes and spiders. The first model introduced was the Giulia saloon, or berlina, and this basic floorpan was used for all future Giulia derivatives such as; the Giulia Berlina Ti and Super and the Duetto, Roundtail, 1750 and 2000 Spiders as well as the Montreal and Junior Zagato. It is the Bertone designed coupe, however, that has become the most popular version of the 105 Series cars.

The coupe was launched in 1963 as the Giulia Sprint GT. The car was designed by Giorgetto Giugiaro while at Bertone in the classic, modern coupe style of the period with its elegant proportions and pillar and window treatment. It originally featured the famous step-front, or scalino, bonnet design with its aerodynamically efficient, stepped leading edge. The coupe was also offered as the GTC, a four seater convertible only available in the earlier step front body shell. The coupes were all available with 1300cc, 1600cc, 1750cc and 2000cc twin cam, four cylinder engines during its lifetime, though the GTC was supplied with the 1600cc engine only.

  

  

The coupe body was also used for the competition GTA and GTAm versions. Alfa Romeo was very active in motorsport, and  Autodelta, the racing division of Alfa, developed a car for competition closely based on the roadgoing model. These cars were named GTAs, the 'A' standing for "Alleggerita", Italian for lightweight. The GTA was produced first in 1965 as a 1600 (1570 cc) and later as a 1300 Junior version. The GTA was also manufactured in either street (Stradale) or pure race (Corsa) trim. The GTA had aluminium outer body panels instead of steel, (the inner steel panels were also of thinner gauge and the inner and outer panels were bonded and pop-riveted together), magnesium alloy wheels, clear plastic side windows, an aluminium rear upper control arm, different door handles and quarter window mechanisms, and lightweight interior trim. The engine had a new double ignition cylinder head (called twin plug) with a Marelli distributor from a Ferrari Dino. For homologation 500 cars were made for racing and road use. The GTAm was produced by Autodelta between 1969 and 1971 and a 1750 GTAm (later called 2000 GTAm when the 2000 GTV was introduced) was created in 1969. The title "Am" is believed to mean Alleggerita Maggiorata (Italian for lightweight enlarged).

  

The other popular body style was the saloon version. Alfa Romeo was one of the first manufacturers to put a powerful engine in a lightweight car for mainstream production. The Giulia weighed about 1,000 kilograms (2,205 lb). The car was equipped with a light alloy twin overhead camshaft four-cylinder engine and variants offered were 1.3-litre (1,290 cc) or 1.6-litre (1,570 cc). Giulias were noted for their lively performance among saloons of their era, especially considering the modest engine size. The popular Super version with the twin carburettor 1.6 litre engine had a top speed of 106 mph and 0 to 62 mph took about 12 seconds. This performance was better than many sports cars of the late 1960s and early 1970s. The styling was quite conventional but with a great amount of detailing. It was a car with a particularly low drag coefficient for its era. For example, the drag coefficient of the Giulia was lower than that of a Porsche 911 from the same period. The saloons were available in the following variants: Giulia Ti, Guilia Ti Super, Giulia 1300 and Giulia Super. In 1974 the saloon range was re-released as the Nuova Super range available in 1300cc petrol, 1600cc petrol and 1800cc diesel versions.

 

As mentioned above the 105 series was also available as the Junior Zagato which had a 2 seater coupe body designed by Ercole Spada for Zagato. These were originally offered by Alfa Romeo as the GT 1300 Junior Zagato and then later as the GT 1600 Junior Zagato with a longer wheelbase.

Finally, the Montreal model, which was originally a showcar, designed by Marcello Gandini at Bertone, for the Expo67 in Montreal, Canada, held in 1967. The original show car was based on the 105 series floorpan with a 1600cc engine but the production version used a 2593cc V8 engine, derived from the Tipo 33 racing engine. This production version was first shown at the 1970 Geneva Motor Show. The Montreal was in production from 1971 until 1977.

The main Alfa Romeo Giulia 105 Series ceased production in 1976.
