Lighter, less powerful… but above all, without hybrid: the Rally1s may have the same face in 2025, but inside, it will be very different! This Friday, the FIA formalized the end of the hybrid system for the 2025 and 2026 seasons, pending the new regulations planned for 2027. The end of the hybrid in WRC was validated by electronic vote during the last World Motor Sport Council .
Introduced in 2022, the hybrid system – supplied by the company Compact Dynamics – has never ceased to pose problems and create certain controversies. Too expensive, unreliable, this electrified engine has had its share of criticism for three years. To the point that the FIA has authorized, since this season, the entry of non-hybrid Rally1s: Martins Sesks notably benefited from this during the Polish Rally last June, for his first appearance in the premier category.
Removing the hybrid system allows teams to have cars that are less technologically complex, more reliable but above all, less expensive. The bridge between Rally2 and Rally1 for young drivers is also simplified. To counterbalance the absence of the hybrid system, and therefore the additional power, the Rally1s will be lighter: their weight will increase from 1260 kg to 1180 kg (i.e. a weight reduced by 80 kg).
On the other hand, the air intake flange will be reduced by one millimeter and will go from 36 mm to 35 mm in 2025 to slightly reduce the power of the thermal engine. Thus, the non-hybrid Rally1s will have a power-to-weight ratio similar to the hybrid Rally1s. The fuel used will always be 100% sustainable.
“The rich heritage and unique appeal of this sport, which is so dear to me, is invaluable, and we are determined to preserve its future, said FIA President Mohammed Ben Sulayem. This development is important not only for the championship's stakeholders to adapt to the changing energy landscape, but also to control costs. By focusing on sustainable fuels and simplifying car technology, we are ensuring the WRC remains exciting for fans and achievable for competitors. »
