The history of the 911 is one of almost Alfred Hitchcock-like complexity, leaving many in a welter of names such as S, Targa, E, L and Carrera. Our narrative commences at the 1963 Frankfurt Motor Show when Porsche displayed its vision of the future, and ends in 1989 when the 964 employed 85% new parts to create the next version of one of the world’s most recognisable sports cars.
