The 2600 Sprint was the ultimate incarnation of the twin-cam straight six. Still considered very much a grand tourer, the coupé lacked the agility of its smaller cousins, despite its sports car looks. The torquey engine made this a car for covering continents – despite its prodigious straight-line pace. Significant because, along with the Gordon-Keeble GK1, this was one of Giorgetto Giugiaro’s first designs, laying the foundations for a significant career ahead. Unlike more mainstream Alfas, parts for the 2600 Sprint are not so readily available.
