A great story about a Porsche which never made it. This was an engineering project to create a racing coupe with a "folding" roof. We think it bears some resemblance to a Saab Sonnett when viewed from the front, but was based around the 911 and probably had influence from the 904. That makes it strange as the beautiful 904 was in production around this time, and the folding roof idea seems like pure novelty. The Swiss Porsche Diba based on the 911 platform came later, but also has a lot of similarities. See the original story at the link below.
