The FIA World Motor Sport Council has approved additional provisions for the 2027 FIA World Rally Championship Sporting Regulations, marking another significant step towards the implementation of the championship’s new regulatory framework. The latest decisions outline key elements of the series’ future, including participation requirements, category classifications and points allocation.
The updated regulations formally introduce the Rally1 category as the championship’s premier class, bringing together two different car specifications. The first will comprise new-generation ‘WRC Cars’, built according to the WRC27 technical regulations, while the second will feature ‘WRC Kit Cars’, based on existing Rally2 machinery and equipped with an approved aerodynamic upgrade package. This package will include new front fenders, a front bumper and a rear aerodynamic device. From 2027, both specifications will compete within the same top category.
A revised championship structure will also be implemented, with the Manufacturers’ Championship replaced by a new Constructors’ Championship. The change will allow traditional automotive manufacturers and independent tuners to compete for the same title under a unified classification. To be eligible for the Constructors’ Championship, participants must enter every round of the season.
The regulations will also establish a new WRC Teams’ Championship, contested across seven nominated events. Teams must include a compulsory overseas round and the season-ending event in their participation to qualify for the title. Both the Constructors’ Championship and the WRC Teams’ Championship will be exclusively open to cars competing in the Rally1 category.
The championship’s established support categories will remain unchanged, with WRC2, WRC3 and the WRC Masters Cup all set to continue in 2027, maintaining opportunities for competitors across different levels of the sport.
In a further technical adjustment, the maximum turbo restrictor diameter for both new-specification Rally1 Cars and WRC Kit Cars will increase from 32mm to 33mm. The change is designed to provide greater engine performance for both specifications competing in the Rally1 category.
The approved provisions also give the FIA the flexibility to introduce additional technical or sporting measures whenever necessary to preserve an appropriate performance gap between vehicle classes. This provision will be particularly important during the transition to the new regulations in 2027 and 2028, helping maintain competitive balance as the new-specification Rally1 Cars compete alongside upgraded WRC Kit Cars.
