Global Rallycross

Qualifying was conducted over the course of one hour. The field was broken up into small groups that took to the track in 10-minute sessions. Seeding for heat races was determined by a driver's qualifying lap time.

A race weekend consisted of one or two rounds of heats that count for championship points, as well as a semifinal. The heats always consisted of three sessions of four or five cars each, while the semifinals consisted of two sessions of six or more cars each. In the case of an event with only one round of heats, such as a doubleheader race, points were awarded in the semifinal, but not otherwise.

The top three finishers in the semifinals transferred into the main event, giving their teams time to work on their cars while others continue to compete. All drivers who do not make it into the main event via the semifinals would compete in the last chance qualifier for the final four remaining qualifying spots. Ten cars then compete in the main event.

Races began with a standing start, where drivers are given 30- and 10-second intervals before the green. During that time they must activate launch systems, including an anti-lag system, before starting the race. The fastest driver in the previous session was given the inside lane to the first corner.

Each course was equipped with two routes: the main route, and the joker lap route, which each driver must only take once per race. The GRC joker lap route typically shortened the length of the track significantly (while in the FIA World Rallycross Championship the JL detour is longer than the main route, to slow the cars down for a minimum of two seconds), so when a driver takes the joker lap can affect their race strategy. Depending on the venue, the joker lap route may have additional obstacles which significantly slow the cars thus making the main route faster. In mid season 2015, GRC made some changes to the joker lap, where drivers were not allowed to take the joker lap on the first lap.

The penalty box was a new addition to series for the 2013 season, and was designed to deal with on-track infractions without having to red flag or restart the race. In event of a jump start or unsportsmanlike driving, the penalised driver would pull into a 50-metre lane off track, where they would be held until a track official releases them. The penalty box was first used at the first event at X Games Brazil, when Nelson Piquet Jr. jump-started at the beginning of Heat 2.

As of 2014, championship points were awarded only to drivers who had committed to running at least half of the season. Under that point system, one-off drivers were skipped over when points were awarded; for example, if the race winner was not eligible to earn points, the event runner-up would earn first place points. Points were awarded at the conclusion of the event to eligible finishers as follows:

In addition, points were awarded in all rounds of heats and semifinals. First place earned five points, second place earned four points, and so on through fifth place and below, which earn one point. Only drivers who were disqualified from a heat or fail to pull to the starting grid did not receive points for their heats. On race weekends with three rounds of heats, the third round solely determined starting spots in the main event and did not award points.

At the end of the season, the driver to score the most points was crowned Global Rallycross champion. The top two cars per manufacturer also scored points in the manufacturer's championship.

Intermediate points are split into two categories, Race Time points (for race time, regardless of group) and Race Position points (for position in each group), which are scored as follows:
