Global Rallycross

Making its debut at New Hampshire Motor Speedway, Joni Wiman was the inaugural champion after winning all six races.

A race weekend consisted of one or two rounds of heats that count for championship points, as well as a semifinal.

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.

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.

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.

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.

At the end of the season, the driver to score the most points was crowned Global Rallycross champion.
