1977 Porsche 935 K3


The Porsche 935K is built by the German Porsche tuner, Kremer Racing, according to Group 5 regulation. Inside the body, it is what you may call an evolved-version of the works machine 935/77. At the 24 Hours of Le Man, the 935K3 racing for Kremer won the overall title in 1979. The car continued to show its high potential in various races after that.

The Porsche 935 was originally developed for the World Championship for Makes, which began in hopes of boosting the popularity of sports car racing. The race was for Group 5 cars: Cars that were more similar to commercially available cars. If it cleared the minimum production number (400), and retained the approved vehicle image (including engine storage area, driving method) , most alterations were allowed. Due to this, the Group 5 was called the “Silhouette Formula”. The Porsche developed the speciality model 935 based on the 930 Turbo. Although the monocoque shell is the same as those of commercially available models, the front was changed to a steel tube space frame, titanium springs, 917 ventilated disc break, a 2856cc flat-six single turbo capable of 590hp, and aerodynamically superior FRP-made flat-nose body were applied. Studying the regulation meticulously, and after careful preparation the 935 overpowered its rivals from its debut.

As the vehicle was sold to privateers from 1977, people began calling the World Championship of Makes “a one make race for 935”. The Kremer Racing, led by the Kremer brothers who had a Porsche tuning shop in Cologne, Germany showed they can hold their own against the factory-backed teams.

From the start of the 1976 series, the brothers raced with original machines like the 935K1 and 935K2; an altered version of 911RSR. For the 1979 season, they developed the 935K3, based on the factory-backed car 935/77. The exterior did resemble the 935/77 but with the aluminum roll cage extended and with a strengthened body, the gear box attached upside down realizing a low center of gravity, equipped with a 3165cc flat-six twin turbo (2943cc for Le Man) complete with an air-cooled single inter-cooler that generates more than 800hp.

With this 935K3, the brothers raced the 24 Hours of Le Man, World Champions of Makes, Germany’s National Championship as a factory-backed team. They also started selling the cars to customers. The success of updating the existing 935 and 930 turbo 953K3 specs, led to the increase of 953K3 on the market.

This particular 935K3 is number 80. In 1977, it was delivered as a 930 turbo with a VIN number of 9307700486 (original owners manual available). The car was brought in to Kremer around 1981 and various alterations were applied to the 935K3/80 including a large rear flap.

The car is equipped with a 3-liter Le Man-type engine. There are no major races on record, but in 1981 and 1982, the car entered the ADAC Auto Cross, and a log book of the records the car raced in is available. Because the car had until recently been racing in international classic races such as the Le Man Classic, FIA HTP papers for this car are available, too. The car is in race ready condition and is eligible to participate in many series, particularly in Europe.

The car is maintained in excellent condition and finished in a striking Jägermeister color.
