The Alfa Romeo 2600 (Tipo 106) 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 with 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 starting in 1950.
