Kremer’s Uber 935 – the ultra-rare K4

In the mid-1970s, Porsche developed the 911 for racing, and in the process, it created the all-conquering 935. In 1978, Norbert Singer was responsible for building the ultimate factory 935, the Moby Dick 935/78, and although this race car had a very short active racing life, it has gone down in history as one of the most iconic 935s of all time. Despite winning only one race, the Silverstone 6 Hours on 14 May 1978, Porsche’s Moby Dick became one of the most copied 911s of its era.

After the Moby Dick 935/78 had raced at Silverstone and in the Le Mans 24 Hours that year, the car was retired, as the factory’s attention turned to the next generation of race cars. However, Porsche allowed some private teams with close ties to the factory, to continue purchasing components and drivetrains for the 935, but they were left to design and produce their own upgraded chassis and bodywork. One of those privateer teams, Kremer Racing, did a particularly good job during the late ‘70s, creating the 935 K1 (1976), K2 (1977) and K3 (1979). Kremer Racing, based in Cologne, Germany, didn’t restrict their work to just mechanical preparation and assembly, but they also developed their own bodywork which really set them apart from the rest of the field.
