Alfa Romeo 2600 Spider
The Alfa Romeo 2600 was Alfa Romeo´s six-cylinder flagship produced from 1961 to 1968. It was the successor to the Alfa Romeo 2000. It has become historically significant as the last Alfa Romeo to have been fitted with an inline six-cylinder engine having twin overhead camshafts. That had been the traditional Alfa Romeo engine configuration since the 1920s, but gave way to four-cylinder engines as the factory oriented its production towards more economical mass-produced car models after the Second World War.
The 2600 was introduced in the 1962 Geneva Motor Show, as a sedan with a factory-built body (2600 Berlina), a two-plus-two seater convertible with body by Carrozzeria Touring (2600 Spider), and a coupe with a body by Bertone (2600 Sprint). A convertible based on the Sprint coupe was shown by Bertone in 1963. It was also named 2600 Sprint, but did not enter production. The 2600 SZ (Sprint Zagato) with fastback coupe bodywork by Zagato, and the limited-edition 2600 De Luxe with six-window sedan bodywork by OSI (Officine Stampaggi Industriale) were introduced three years later in 1965 at the Frankfurt Motor Show.
