A number of changes have been adopted to clarify the requirements for the WRC2 class. Participating teams in the category now have to register no later than the closing date of the fifth round of the 2021 season. To score points, a team must enter two cars in a maximum of seven rallies, including a minimum of one round outside of Europe.

WRC2 Drivers and Teams will be required to nominate to score points as they enter an event and as a result, registered Drivers can enter additional rallies as Priority 2 without scoring points. In regards to points scoring, the highest number of points from six of the seven nominated rallies will count.

Owing to the success of the Power Stage points for the WRC, the same format will now be extended to the WRC2 and WRC3 categories.

In WRC3, with the view to restore pre-COVID regulations, the number of rallies counting for the championship has been reinstated from five to seven, with the best five rounds counting for the championship points. Specific requirements have also been added to restrict the class entry to aspiring drivers developing their skills.
Another year, another attempt to make this work. Here's hoping all involved enter into the spirit of making this look sensible...
