The classes
One formula — GT3 — sliced into four cups by driver rating rather than machinery. Pro crews fight for outright wins and the overall championship. Gold Cup runs Gold-rated line-ups with one Silver permitted, Silver Cup is all-Silver, and Bronze Cup is built around a Bronze-rated amateur — at sprint rounds with at most a Platinum alongside, at endurance rounds with Silvers eligible too. Every race therefore produces several winners: a Silver Cup car twelfth overall can still bank maximum class points. The Bronze Cup carries a serious season prize — contest every round and win it, and an automatic LMGT3 invitation to the 24 Hours of Le Mans follows.
The races
Two parallel cups of five weekends each. The Sprint Cup runs two one-hour races per weekend with two-driver crews and a mandatory pit-window driver change. The Endurance Cup runs three-hour races at Monza, the Nürburgring and Portimão, six hours at Paul Ricard, and the 24 Hours of Spa as its centrepiece, with crews of three or four — Pro cars capped at three at Spa. Qualifying splits the 50-plus car grids into two groups, with aggregate times across three segments setting endurance grids.
Points
Top ten score in each class and the pole-sitter takes a bonus point. Two gates apply: a car must cover 75% of the winner's distance to be classified, and a driver must complete at least 25 minutes of the race to share the points. Three-hour races pay the classic 25-18-15-12-10-8-6-4-2-1; the six-hour Paul Ricard scales up to 37.5 for the win; sprint races pay 16.5 per win so the two cups carry near-equal season weight. Spa pays three times over — a reduced scale topping out at 12 for the leaders at the six- and twelve-hour marks, then full points at the flag, plus points for the Super Pole top three. It is comfortably the most valuable race of the year.
The championships
The Sprint Cup and the Endurance Cup each crown drivers and teams, overall and in every cup class — and adding the two together decides the overall GT World Challenge Europe titles. Teams running multiple cars count only their best finisher each race. Win your cup in both disciplines and the combined crown usually follows; split form between sprints and enduros is how titles slip away.
