FIA Officially Confirms 2027 WRC Sporting Regulations
Highlights
- FIA approved new sporting rules for 2027 World Rally Championship
- Rally1 class will include both WRC Cars and WRC Kit Cars
- New turbo restrictor size increased to 33mm, boosting power by 15 hp
- Constructors’ Championship replaces Manufacturers’ title for Rally1 teams
- New WRC Teams’ title contested over seven nominated events
- Rally6 category updated for cost-effective, production-based entry-level cars
The FIA ratifies key sporting regulations for the 2027 World Rally Championship following the World Motor Sport Council meeting, setting a clear framework ahead of next season’s technical overhaul.
Rally1 remains the top tier but now encompasses two car types: WRC Cars and WRC Kit Cars, each built to different rules yet targeted for comparable stage performance.
The architecture seeks competitive balance and lower entry barriers, encouraging new manufacturers and tuner teams to enter while containing costs.
Rally1 will feature both WRC Cars and WRC Kit Cars in 2027.
Project Rally One and RMC Motorsport are developing new WRC Cars to the 2027 technical rulebook, while Rally2 manufacturers can join via a €7,500 update kit for Kit Car eligibility.
The kit adds front fenders, a front bumper, and a rear aerodynamic device. M-Sport is the first confirmed adopter, recently testing an updated Ford Fiesta Rally2 in Spain.
Turbo restrictor grows to 33mm, delivering roughly 15 horsepower more than current Rally2 units.
Both WRC Cars and Kit Cars will run a 33mm turbo restrictor, up from the 32mm used in Rally2, providing an estimated 15 horsepower increase without inviting runaway spend.
The intent is sharper performance with contained development, preserving value for incoming teams and existing Rally2-based entrants.
On governance, the Manufacturers’ title becomes the Constructors’ Championship, open to Rally1 manufacturers across the full 15-round season.
Manufacturers’ title is rebranded as the Constructors’ Championship across all 15 rounds.
A new WRC Teams’ title will be fought over seven nominated rallies, including one overseas event and the finale, suiting part-season programmes.
A seven-event WRC Teams’ title supports competitive partial-season entries.
That format is well aligned with emerging operations like Project Rally One and RMC Motorsport, which are unlikely to contest every round.
WRC2, WRC3, and the WRC Master Cup remain unchanged, preserving the established competitive ladder.
Entry-level Rally6 rules are refreshed for affordability, with build and running costs projected between €35,000 and €47,000.
Rally6 cars use two-wheel drive and production four-seat bases, with 1.6‑litre turbo or 2.0‑litre naturally aspirated engines.
Cost control extends to production brakes and tyres, conventional gearboxes, and fixed dampers, while maintaining strong safety standards.
Strategic planning will hinge on the 2027 WRC calendar, particularly for teams targeting the seven-event title.
Drivers including Adrien Fourmaux and Sébastien Ogier are already weighing the implications of the reshaped landscape.
