🇳🇱 Calvin de Groot

Calvin de Groot is a semi-professional endurance racing driver competing in multiclass championships at the Nürburgring. He drives for SRS Team Sorg Rennsport in the Nürburgring Langstrecken-Serie, where he races Porsche Cayman GT4 Clubsport machinery in Cup 3 and front-wheel-drive and rear-wheel-drive turbocharged production cars in the VT2 classes. He holds an FIA Silver grading, which places him below the full-professional grades in sportscar and endurance racing.[1]

De Groot has completed two seasons on record, with 15 starts across the 2025 and 2026 Nürburgring Langstrecken-Serie seasons yielding one win and nine podium finishes. He took a single start in the 2026 Nürburgring 24 Hours. His rating of 2,630 reflects a semi-professional standing; his most telling victories have come against professional-graded drivers, including a finish ahead of Ben Tuck, a Silver-graded professional who has contested the European Le Mans Series and the World Endurance Championship.[2]

De Groot regularly races against two entry-level professionals who dominate his classes: Daniel Zils, a five-time VT2 Hecka champion at the Nürburgring Langstrecken-Serie with 135 starts in the series, and Philipp Leisen, a six-time champion at the same venue with 116 starts. De Groot typically finishes behind both drivers in shared races, placing him in the second tier of a field that mixes amateurs and semi-professionals with established competitors across the Nürburgring's multiclass grids.
