The BOSS series was created by Roger Cowman & Mark Haddon in 1995 under the regulations of the RAC Motor Sports Association and raced mainly in Great Britain.

After the 2009 EuroBOSS season, Marijn van Kalmthout, Klaas Zwart (founder of Ascari Cars and the Ascari Race Resort), Henk de Boer, and Frits van Eerd decided to split off and organize their own race series.

Eventually, the final 3 races of the 2010 EuroBOSS season were cancelled and the series was disbanded, with competitors switching over to BOSS GP.

[1] As of 2013, two rounds of the BOSS GP series have formed an official German championship sanctioned by the DMSB.

In the 2018 season, BOSS GP ran for the first time a support race for two major motorsports events: the German Grand Prix at Hockenheim and the Red Bull Ring round of the DTM Championship.
