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.[5] The Type 105 Giulia was equipped with a light alloy twin overhead camshaft four-cylinder engine similar to that of the earlier Giulietta (750/101) range, available in 1.3-litre (1,290 cc) and 1.6-litre (1,570 cc) versions. 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.
