The Alfa Romeo Giulia (105 series) is a sports sedan which was produced by Alfa Romeo in Italy from 1962 to 1978. Alfa Romeo was one of the first manufacturers to put a powerful engine in a light-weight 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, similar to that of the earlier Giulietta models range. Engine capacities offered were 1.3-litre (1,290 cc) or 1.6-litre (1,570 cc). Various configurations of carburetors and tuning produced power outputs from about 80 to about 110 bhp (55 to 75 kW). Almost all Giulias made had a 5-speed manual transmission. Giulias were noted for their lively performance among sedans of that era, especially considering the modest engine size. The popular Super version with the twin carburettor 1.6 litre engine had a top speed of 170 km/h (106 mph). 0 to 100 km/h (62 mph) took about 12 seconds. This performance was better than many sports cars of the late 1960s and early 1970s. When leaving the factory all variations of the Giulia originally fitted either Pirelli Cinturato 165HR14 tyres (CA67) or Pirelli Cinturato 155HR15 tyres (CA67).
The styling was quite straight forward, but with a great amount of detail. The engine bay, cabin and boot were all square shaped. But the grill, the rooflines and details on the bonnet and boot made for an integrated design from bumper to bumper. It was also a car with a particularly low drag coefficient for that era. For example, the drag coefficient of the Giulia was lower than that of a Porsche 911 from the same period.
