How a three-hour GT World Challenge race works

The GT World Challenge Europe season ends at Portimão on Saturday 17 October with a three-hour race. Three drivers share each car, the field is split into four classes, and the cars are balanced against each other by the organiser. This page explains how it all fits together, based on the 2026 Sporting Regulations of organiser SRO.

What is GT World Challenge Europe, and how do Sprint and Endurance differ?

GT World Challenge Europe is SRO’s championship for GT3 cars. The 2026 regulations allow a maximum of ten events, split into two cups (article 4). The Endurance Cup consists of three-hour races, one six-hour race and the 24 Hours of Spa. The Sprint Cup runs weekends with two races of up to one hour each.

Both cups count for their own titles, and points from both are added together for the overall drivers’ and teams’ championship (article 5.1). Portimão is a three-hour race, which the regulations call Case A, so it counts for the Endurance Cup and for the overall title.

Who drives, and what are the Pro, Gold, Silver and Bronze classes?

Every driver is graded by the FIA as Platinum, Gold, Silver or Bronze, based on their record (article 12.1). The details are in GT World Challenge classes explained. A team then enters its car in one class, and that class decides which drivers it may use (article 111):

Class	Drivers allowed (maximum grading per seat)
Pro	Any grading
Gold Cup	Gold, Gold, Silver
Silver Cup	Silver, Silver, Silver
Bronze Cup	Platinum, Silver, Bronze

In a three-hour race each car must use exactly three drivers, named Driver 1, 2 and 3 before the weekend starts (article 112). The Bronze driver in a Bronze Cup car must be an amateur: a former professional is only accepted if SRO’s Sporting Board is satisfied they now race at Bronze level (article 11.3.1).

There is no separate Pro trophy. The Pro cars fight for the overall win and the overall title, while Gold, Silver and Bronze each have their own classification and podium (articles 5.1 and 145.1). The Bronze Cup has an extra prize: the leading full-season Bronze car earns an invitation to the 2027 24 Hours of Le Mans (article 5.5). Read more in our piece on the Bronze Cup title fight at Portimão, and see every car and class in the Portimão entry list. One of the best-known names on it is Valentino Rossi.

How does qualifying decide the grid?

Qualifying is split into three periods of ten minutes, one per driver (article 135.4.3). Each period runs twice: first for the Bronze and Silver Cup cars, then for the Gold Cup and Pro cars. Driver 1 drives Q1, Driver 2 Q2 and Driver 3 Q3. The grid is set by the average of the three drivers’ best times, so a team is only as fast as its slowest driver. More in How GT World Challenge qualifying works.

Each driver also has to use one fixed set of tyres, in qualifying and again during their own stint in the race (article 123.1).

How does a three-hour race run, with pit stops and driving times?

The regulations allow two formats for a three-hour race (article 118.5). For Portimão the provisional table lists two mandatory pit stops. At each one the car must be refuelled for at least the minimum refuelling time, all four tyres must be changed in that time, and a new driver must take over. With three drivers and two stops, every driver gets one stint.

No driver may stay in the car longer than the maximum driving stint (MDS). If a Full Course Yellow or Safety Car period falls in a stint, the longer extended stint time (EDS) applies (article 118.4). The exact limits for Portimão are still marked “to be confirmed” and will be set by a Stewards’ bulletin during the weekend. As a reference: at the Nürburgring the provisional figures were 64 and 69 minutes. A driver who overruns gets a drive-through penalty, or a stop-and-go of up to 30 seconds if the overrun is five minutes or more.

The minimum refuelling time is set per event by the Stewards (article 118.5). Refuelling too quickly costs the missing time, rounded up to five seconds, plus a penalty that starts at ten seconds and grows with each repeat (article 118.7.1).

What is Balance of Performance?

Ten manufacturers race different GT3 cars in this series, so SRO evens them out with a Balance of Performance, or BoP (article 507.1). Its Technical Board can change any parameter it needs, such as each car’s minimum weight. A new BoP document is confirmed by the Stewards for every event and may be adjusted up to 120 minutes before the race starts. A team that misleads the process or outperforms what the data predicted can be penalised. See How Balance of Performance works in GT World Challenge.

What do Full Course Yellow and the Safety Car mean?

When a car stops in a dangerous place or marshals need to work near the track, the Race Director declares a Full Course Yellow, or FCY (article 39.4). All cars must slow to 80 km/h, drive in single file and may not overtake. There are two kinds. In a long FCY the pit lane stays open, and the Safety Car usually follows. In a short FCY the pit entry is closed and cars may only pit for an emergency, such as a puncture, damage or running out of fuel.

For bigger incidents the Safety Car leads the field, with cars no more than five car lengths apart (article 40.2). You may know Code 60 from other series: that procedure does not appear in the 2026 GT World Challenge regulations. Read more in What happens under Full Course Yellow and the Safety Car.

How are points awarded?

The top ten in a three-hour race score points, overall and in each class (article 106.2):

Position	1	2	3	4	5	6	7	8	9	10
Points	25	18	15	12	10	8	6	4	2	1

The car with the fastest average qualifying time earns one point for its drivers and team, overall and in each class (article 106.1). If a race is stopped and cannot be resumed, no points are given if the leader has done fewer than two laps, and half points if the leader has done less than 75% of the race time (article 6.2).

One rule matters at the season finale: 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 (article 5.3). All scales, including the six-hour race, Spa and the Sprint Cup, are in How GT World Challenge points and titles work.
