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.

The cars details:

The wheel housings, side sills as well as the front- and rear bumper were remodeled and improved at the so-called „dp11 Red Evolution“ body which is coated in Porsche guards red (80K). The windows of the lightweight doors consist of hardened plexiglass. Even the water drains were removed. All body parts are made of carbon or glass fiber reinforced plastic (GFRP).

The vehicle inhabits a H&R suspension coil over system and adjustable dp-stabilizers type RSR. The front axle head bearings as well as the turbo rear axle guides are Unibal-mounted and the front axle PU guide sockets are supplied by Superpro. The welded strut brace as well as the brake system of a 911-3.3-Turbo deserve special mention. The wheel-tire-combination with Fuchs rims in the dimensions 9 x 15 are assembled with Michelin semi slicks TB in 225/55-15 on the front axle and in 13 x 15 with 335/35-15 on the rear axle.

The 3.500 cm³ (213,5831 cubic inch) capacity racing engine is equipped with a mechanical fuel injection system with individual throttle valves, a dual ignition system as well as 911-RSR camshafts. The results are mighty 374 hp (275 kW). Edelweiß Motorsport coordinated the mechanical fuel injection pump on a dynamometer. The transmission type 915 with limited slip differential, steel synchroniser rings and oil cooling received an elevated shifter and shortened shift travels.

Even the interior endured an extensive upgrade. While enjoying the Lollipop race seats in the 935 style, the driver is looking through a 350-mm Momo steering wheel on a carbon dash board with carbon knee rails. The coated tin in the interior is furnished with a 964 RS style light-weight velor carpet. Ultimate protection for the passenger is provided by a welded, red coated safety cell as well as 4-point professional harness by Schroth.

Also the bonded windshield type 993, a light motorsport battery, a custom-made racing cable bundle and a carbon clubsport tank with 80 liters capacity are worthy special attention. The result of 940 kg (2072 lb) unladen weight (without fuel) is remarkable!
