Portimão finale: how the three-hour GT World Challenge race works
More than 60 GT3 cars, four classes and two mandatory stops decide the season, with Max Verstappen making his series debut in the #3 Mercedes
The GT World Challenge Europe season ends on Saturday at the Algarve International Circuit with a three-hour race. According to SRO, more than 60 GT3 cars from ten manufacturers are entered, and several titles are still open. Here is what decides the evening, from qualifying to the flag.
Four races on one track
Every car runs in one of four classes: Pro, Gold, Silver or Bronze. The Pro cars fight for the overall win, while Gold, Silver and Bronze each have their own classification and podium. The Bronze Cup carries an extra prize: the best full-season Bronze car earns an invitation to the 2027 24 Hours of Le Mans. Read our preview of the Bronze Cup and overall title fight, and find every car and class in Tessa van Duin’s entry list.
The grid is an average of three drivers
Each car has exactly three drivers, and each drives one ten-minute qualifying period. The Bronze and Silver cars run first, then the Gold and Pro cars. The grid follows the average of the three best times, so one star driver cannot carry a car to pole on his own. The fastest average earns one championship point, overall and in each class.
Two stops, two driver changes
The 2026 regulations list two mandatory pit stops for Portimão. At each one the car is refuelled for at least a set minimum time, all four tyres are changed and a new driver takes over. Every driver has a maximum time in the car, which the Stewards confirm by bulletin during the weekend. Staying out too long costs a drive-through, or a stop-and-go when the overrun is five minutes or more.
Twenty-five points for the winner
The top ten score 25, 18, 15, 12, 10, 8, 6, 4, 2 and 1 points, both overall and within each class. Points from this race count for the Endurance Cup and for the overall championship, which combines the Sprint and Endurance results. The full rules, including the Balance of Performance and Full Course Yellow at 80 km/h, are in our explainer How a three-hour GT World Challenge race works.
Verstappen races, but cannot score
The best-known newcomer is Max Verstappen, who shares the #3 Mercedes-AMG of Team Verstappen Racing with Ben Barnicoat and Chris Lulham in the Pro class. Under article 5.3 of the regulations, a driver entered for the first time this season in a class at one of the last two Endurance Cup events does not score drivers’ points. Portimão is the last of them, so Verstappen’s own result will not show in the drivers’ standings. We followed his road to this race in the seven weekends towards his debut. He is not the only famous name in the field: see our profile of Valentino Rossi.
Our hunch
With titles open in several classes, the decisive moments may come in the pit lane rather than on track. Two mandatory stops, a fixed minimum refuelling time and a driver limit per stint leave little room to gain time in the pits, so a well-timed Full Course Yellow or Safety Car can do more for a class title than a fast lap.
Friday 18:55, Saturday 18:00
Qualifying is on Friday 16 October at 18:55 Dutch time, and the three-hour race starts on Saturday 17 October at 18:00. SRO streams both free on its GT World YouTube channel.
