FIA will drop plug-in hybrid in Rally1 cars in 2025. Modifications to the technical regulations proposed by the WRC Commission confirm the move, which will see Rally1 cars powered solely by IC engines next year.
This decision follows extensive discussions with key stakeholders, with the crucial reason cited as increasing costs. Dropping the hybrid system enables teams and manufacturers to reduce their overall expenditure. This means, for 2025, with the hybrid out of the picture, rally cars will become easier, lighter, less complex and cheaper to run.
For 2025, the minimum weight of Rally1 cars will also be lowered from 1,260kg to 1,180kg and the air restrictor size will be reduced from 36mm to 35mm to maintain an equivalent power-to-weight ratio between the 2024 and 2025 vehicles.
FIA has also highlighted the WRC-counting ORLEN 80th Rally Poland in June, where Mārtiṇš Sesks demonstrated the potential of the concept as he set four top-three stage times and held second place for three stages during his Rally1 debut driving a Ford Puma without a plug-in hybrid unit.
FIA President Mohammed Ben Sulayem said, “This development is important not only for the championship’s stakeholders to adapt to the evolving energy landscape, but also for containing costs. By focusing on sustainable fuel and simplifying car technology, we’re ensuring the WRC remains captivating for fans and achievable for competitors.”
FIA chief technical and safety officer Xavier Mestelan-Pinon said, “Once again, we have highlighted the championship’s ability to adapt without diluting the sporting spectacle, while responsibly embracing the challenges of our times. We are also pleased that the use of 100% sustainable fuel remains a cornerstone of the championship’s commitment to reducing its environmental impact.”
