Constantin Grimminger (born 14 July 1992) is a German simracer who started his career in 2005. Born into a family with motorsports background, Grimminger was early interested in various racing series.

He co-founded Race4Speed together with Martin Jatzek and Carlos Frau in 2013.


Sim racing career

Grimminger started his career in mid-2005, using CTDP's F1 2005 modification for F1 Challenge 99-02. After appearing with the Jordan EJ15 in San Marino (he retired from the race) the league shut itself down in order to prepare for 2006, a plan that never worked out.

He later joined another F1 league, based on the 4racers.de forum, where he scored his first podium in a race of five in Barcelona, driving Fisichella's Renault R26. After missing the next round, the series shut down aswell.

In the late first decade of the millenium he joined the league F1C-Fun, a league with career system, where he gained his first major success by finishing third in the rookie-level A1GP Championship and thus graduated to the league's GP2 series. However, he wasn't able to keep up his success and dropped off the season early.

This left Grimminger without a league drive until 2011, when he partnered up with long-time friend Martin Jatzek to start the Race4Speed precessor GP2League.com, a league which lasted for only three rounds. However, both drivers weren't willing to let go and finally founded Race4Speed. Grimminger was close to become the first champion of Race4Speed, but ultimately lost out to Carlos Frau in the 2013 GP3 league.

Over the years he raced in nearly all Race4Speed series and gained major success there, but also he had some appearances in other leagues. Unlike other drivers, he competed as keyboard driver in most of his early career before finally buying a used Logitech Driving Force GT in mid-2014 from his then-GP3 team mate Benjamin Röske.

After the 2016 season finished at Race4Speed, he stepped away from circuit racing to join GP Latina's NASCAR series for the final races, racing with his team Unnameds Racing Development.

However, being motivated after his P4 finish in the 2016 R4S F3 driver's championship, he set himself for another attack on finally winning a driver's championship and thus rejoined the R4S series' of GP1 and F3, aswell as GP Latina's NASCAR series. Grimminger also upgraded his hardware and bought a Logitech G29 for 2017. This plus a huge gain in speed brought him the vice championship of the 2017-I R4S GP1 season, where he was even able to challenge his long-term R4S rival Marc Stwerka occasionally. In the latter half of the year he joined multiple championships as a stand-in and looked outside of R4S for further challenges. This resulted in the closure of Race4Speed and his sim racing team.

In his career he earned himself a reputation as a reliable and extremely consistent driver with a defensive attitude. He is well-known for being persistent in difficult situations, for example when he stayed with Team Alfa Romeo in the 2015 DLM WTCC championship for a second season despite offers from much more competitive manufacturers as Ford, Chevrolet and Citroën.

Personal life

Besides sim racing, Grimminger used to be a successful rower, a hobby which often limited him on his sim racing career.

He is a huge fan of ex-F1 driver Giancarlo Fisichella, which led to his modding nick name fisicoF1. Under this name he's well-known in the F1 Challenge 99-02 and rFactor communities for working on several mods, for example the 2010-15 GP3 mods by World Sim Team, the 2014 GP2 mod by German Painting Group and various Formula 3 mods. After leading modding group World Sim Team from 2014 until 2020, he's currently part of WST-succeeding group .Race9 Modding.
