Earl Bamber, Nicky Catsburg, David Pittard and Felipe Fernandez Laser scored a dominant win in the 51st running of the German endurance classic, also setting a new distance record of 162 laps - three more than the previous benchmark.
It marks the first victory by a non-German marque in the event since the triumph of Zakspeed's Chrysler Viper GTS-R in 2002.
At the beginning of the race, the Frikadelli machine was locked in battle against three Mercedes-AMG GT3s, two from GetSpeed and the polesitting HRT car.
As darkness fell, however, the Mercedes contingent dropped back and the Rowe Racing BMW M4 GT3 of Maxime Martin, Sheldon van der Linde, Dries Vanthoor and Marco Wittmann emerged as Frikadelli's closest rivals. Both cars engaged in a thrilling battle circulating around two minutes apart.
The result was slightly distorted by the fact that the BMW stopped two laps later and was thus able to reduce the gap to less than one minute in the final part of the race due to the shorter pitstop time at the last round of stops. Pittard ultimately beat Vanthoor home by 26.287 seconds.
