Porsche 911 Modified

The vehicle in detail

After long consideration it´s clear, Ekkehard Zimmermanns last synthesis of the arts, which he built for himself, is for sale now. The car was maintained in August 2020. As a unique special, the car received an autograph on the 80th birthday of its maker on the carbon knee rail of the passenger side. The car is ready to drive without german street approval. Tüv adds another 20k€ to customize engine and exhaust to get it approved.

Ekkehard Zimmermann, born on September 3, 1940 in Peine, Lower Saxony, is a German automobile designer. The well-educated model maker formed his first prototype with a complete body made of polyester material, the “Dingo”, between 1960 and 1962. Two years later, in 1964, he joined the design studio at the Ford factory in Cologne. Before founding his own company in Bergisch-Gladbach in 1973, he worked in the cathedral city for the next nine years. The first commissioned work for the famous Porsche Kremer racing team in Cologne made him known to an international audience. From 1976 on, Zimmermann realized the mold construction of all Kremer Porsches in motorsport. On June 10, 1979, one of his creations, the Kremer Porsche 935 K3, won the Le Mans 24 Hours. With the end of the collaboration in 1983, the focus shifted more and more towards exclusive small-series vehicles such as the Porsche 935 dp II, which was inspired by the successful work in racing. In 2003, Ekkehard Zimmermann, now 63 years old, returned to top-class motorsport after 20 years. The dp5 based on the 996 generation Porsche 911 turbo shaped the VLN long-distance races on the Nürburgring-Nordschleife as “Turbinchen” until 2005. As one of his last major projects, the father of two modeled the Kremer Porsche 935 K3, which he created himself in 1981, similar to the original between 2015 and 2017. On September 3, 2022, Ekkehard Zimmermann, who lives in Overath in the Rhineland, will celebrate his 82nd birthday.
