2020 Having been slated to make his car racing debut in the Lamera Cup at
Misano in 2020, Gehrsitz instead debuted in the Porsche Super Sports Cup at the
Hockenheimring owing to the effects of the
COVID-19 pandemic on the racing schedule. He started his career out in brilliant fashion, winning his first two races in
GT4 machinery. At the GTC Finale held at the same circuit in November, Gehrsitz finished the endurance race in third, before being disqualified for an operational error, before winning the sprint race.
2021 For the 2021 season, Gehrsitz would move to compete in the
Michelin Le Mans Cup, driving in the
LMP3 category for
Phoenix Racing. Partnering Hamza Owega, the German would qualify second for the opening two races, scoring a seventh and fourth place in the races, before taking his first pole position at
Monza. He made good use of his grid spot, remaining in first before handing over the car to Owega at the midway point of the race, before their car suffered a mechanical issue, forcing them to retire. Another pole followed at the penultimate round in
Spa-Francorchamps, where the team finished fourth, before Gehrsitz missed the season finale, meaning he dropped to ninth in the standings by season's end. At the end of the year, Gehrsitz made his debut in the
European Le Mans Series, driving for
Eurointernational in the season finale at
Portimão.
2022 Gehrsitz competed in the
Asian Le Mans Series at the start of 2022. Driving alongside Jürgen Häring and Marco Seefried in the GT-Am class, the team took four podiums and ended up third in the championship. Gehrsitz's main campaign would lie in the
European Le Mans Series, where he raced for
United Autosports in the LMP3 class alongside
Bailey Voisin and
Josh Caygill. His season started out strongly, as, having run first during his stint, teammate Caygill finished the race in
Le Castellet in third, which turned into second once a car ahead had been disqualified. The following rounds would bring less success however, as two retirements sandwiched a fifth and ninth place. At the season finale in the
Algarve, Gehrsitz and his teammates took another podium finish, leading them to take eighth in the drivers' standings. Following the end of the campaign, Gehrsitz was selected as one of the designated Rookie Test drivers for the post-season rookie test in the
World Endurance Championship. The German drove in the LMGTE - Am category.
2023 The 2023 season saw Gehrsitz switch back to the world of GT racing, where he teamed up with
Porsche works driver Sven Müller at Team Joos Sportwagentechnik in the
ADAC GT Masters. == Personal life ==
