Project 'Racing Coupé'

The story of the forgotten Porsche began in 1964. Back then, this particular Porsche 911 was happily running along in its standard configuration. Then, in 1966, it would be sent to the Automotive Engineering department at the University of Aachen.

The mission: turn it into a 'racing coupé' with a folding roof. The design study seems to take at least some inspiration from the Porsche 904 race car and its rear engine cover, which could be seen as a kind of retractable roof.

Body shop at the end of the road

Technical drawings and a miniature model were devised before the in-house body department at the University of Aachen went to work on building a completely new body. To keep the weight low, many parts were fabricated in aluminium, including the characteristic rear louvres and the adjacent 'Targa' rollover bar.

The fact that this Porsche had genuine racing ambitions can also be seen from the arrangement of the instruments on the dashboard: they were subsequently added to the right-hand side. The highlight of the study was undoubtedly the hinged cockpit canopy, integrated in its closed state to flow in harmony with the body line.

Finally, the concept car, complete with its retractable roof, was sent to a paint shop in Würselen, a German town in the Aachen district of North Rhine-Westphalia, where it was given its bright green color. Here, too, the model name Porsche HLS was added in black letters.

Left to rot

What happened next explains why the retractable roof Porsche 911 has, until now, generated not a single entry on Google: it simply disappeared. Presumably, the eccentric study found no favor at Zuffenhausen, so it was simply parked at the body shop and left there—for 40 years.

It was not until 911 expert Manfred Hering of Early 911s was asked whether he could restore the long-forgotten concept that it once again saw the light of day.

"I was asked whether I could restore the Porsche for around 30,000 euros. Of course, I had to say no, but I then tried to buy this unique Porsche," says Hering. "After three years of discussions and negotiations I stood in front of the handsome wreck that had been left exposed to the weather for the last four decades. The original engine and a spare engine were dismantled but came with it—and had already served as a home for several families of mice."

Bright future ahead

Hering has definite plans for the car's future of the car: "In mid-April 2015, I will present the retractable roof Porsche at the Techno Classic for the first time. Then we will study it more closely and attempt to restore as many original parts as possible."

Whether he will, at some point in the future, want to sell this unique treasure is a question we'll save for a later meeting.
