FIA reveals final details of WRC 2027 regulations

The FIA has today confirmed the final elements of the World Rally Championship‘s new technical regulations, which will come into force from 2027.

The 2027 regulations, originally unveiled in December last year, are designed to be more affordable and flexible in a bid to attract new manufacturers and teams to the series.

Cars will be built to a €345,000 cost cap, deliver approximately 300 horsepower, comprise a space frame chassis and utilise some Rally2 componentry. OEMs and tuners will be able to construct cars under these regulations, which will span a 10-year period.

To ensure the WRC’s top class is heavily populated in 2027, the new WRC27-spec cars will compete alongside Rally2 machinery, which again offers more flexibility to manufacturers and teams. Toyota is the only current manufacturer known to be developing a WRC27 car.

Following today’s World Motor Sport Council meeting in Tashkent, Uzbekistan, the FIA revealed details claiming that “the foundations are in place for the championship’s new era in 2027", a move that it said was about "providing stability, clarity and long-term direction for constructors, teams and competitors”.

“The WRC27 technical regulations, originally approved in December 2024, have since undergone a final phase of refinement over the past year, and today’s confirmation of the homologation regulations concludes this process, providing constructors with a clear, long-term structure for the development and production of the next generation of rally machinery,” read a report from the FIA.

“The homologation regulations define and clarify the full homologation procedure for WRC27-type cars and outline the duration and conditions attached to each homologation, as well as minimum production requirements for homologated cars.

“This introduces a formal definition for constructors – bringing the manufacturer and tuner entrants under a singular umbrella as entrants in FIA World Rally Championship. A constructor is the entity responsible for designing and building the WRC27-type car, preparing and submitting the vehicle for FIA homologation, and commercialising the car and its associated components.

“The homologation conditions for WRC27-type cars mandate the production of at least 10 units within 24 months of the homologation date. Constructors must also be capable of supplying at least 10 race-ready WRC27-type cars per calendar year to customers. Where a constructor supplies a second constructor for partial homologation, the minimum production of the base car or car variant may be reduced relative to the supply to the second constructor. In addition, the regulations confirm that the homologation of a WRC27-type car is valid for a 10-year period.”

The regulations stipulate that homologation may only be granted once a constructor has officially registered for the championship, and a homologated car must contest at least 50% of WRC events in its first year with a minimum of two cars per rally, increasing to full participation across all events from the second year.
