Porsche 911 HLS (1964)

The story of the forgotten Porsche began in 1964. Back then, this particular Porsche 911 sports car was happily running along in its standard form, little knowing that in 1966 it would be sent to the Automotive Engineering department at the University of Aachen. The mission: to turn it into a ‘racing coupé’ with a folding roof. The design study seems to take at least some inspiration from the pure racing Porsche 904 and its rear engine cover, which could be seen as a kind of retractable roof.
