Thierry had left the local Genk go-kart track, but the idea of racing never left his brain for even a second. His opportunity to have his first test day in a car came in 2020 when Jos Verstappen had planned a test day in the GT4 with GP-Elite in Portimao. This is where the project really got started. Thierry was constantly improving and getting to grips with the Cayman GT4.
This is when Raymond, his father, decided to do more tests in a GT4 and later made the commitment for Thierry’s first season competing in the Sprint Challenge Benelux. This is where Thierry started developing his first racing skills. Together with Jos and the team, they continued testing throughout the season. This was essential as Thierry had zero race experience, which could be seen in his race craft. The season went well, winning the GT4 title and getting as much experience as possible. Raymond, Thierry’s father, knew that in order to get the maximum out of Thierry, they had to see what Thierry’s potential was and which car/championship could bring him there in the best and fastest way. After the season, Thierry tested with many different teams and cars, as Jos believed this would help him improve his way of communicating within teams and his capability to adapt to different cars. During the winter tests, Thierry had tested GT4s, 991 Cup cars, and Formula 4’s. This is when Jos, Raymond and Thierry had to make the decision for the 2021 season.
