Formula 1’s 2026 power unit regulations, featuring a significant increase in electrical power, are currently under scrutiny. An F1 insider has highlighted that the initial plan for the cars’ electric component has aged poorly, prompting discussions for potential adjustments. The current season has seen drivers vocalise concerns regarding the new hybrid system.
The 2026 regulations introduced a 1.6-litre V6 turbo hybrid engine with a theoretical 50/50 split between the internal combustion engine (ICE) and electrical power. This shift involved the removal of the complex MGU-H and a substantial increase in the MGU-K’s output to 350kW.
Drivers have reported issues with battery management and energy deployment, leading to what is termed ‘super clipping’. This phenomenon results in a noticeable reduction in straight-line performance as electrical power diminishes. The situation often forces drivers into unnatural lift-and-coast driving techniques.
Four-time world champion Max Verstappen has been a prominent critic of the new regulations. He described the driving experience as ‘Formula E on steroids’, highlighting the aggressive energy-harvesting demands.
Former team principal Guenther Steiner expressed surprise at the issues observed during the 2026 Australian Grand Prix. He noted that simulations should have predicted these challenges with greater accuracy.
Pat Symonds, a former F1 technical chief, also criticised the FIA’s approach to the 2026 power units. He characterised the resulting design as a ‘camel’ due to what he perceived as excessive compromises during its development.
Formula 1 CEO Stefano Domenicali has urged patience amidst the early criticism. He stated that drawing premature conclusions about the 2026 regulations is ill-advised, citing F1’s history of adapting to new technical challenges.
Domenicali confirmed that the FIA and Formula One Management are actively discussing potential solutions. He indicated an open approach to addressing the issues, with the F1 Commission considering improvements.
Discussions are already underway to revise the power split for the 2027 and 2028 seasons. Proposals include shifting to a 58-42 split in favour of the ICE for 2027, potentially moving to 60-40 by 2028.
Domenicali also revealed that Max Verstappen has been consulted directly on these planned 2027 regulation changes. Early feedback from simulator sessions has been encouraging, according to the F1 CEO.
FIA President Mohammed Ben Sulayem has even suggested a future return to V8 engines utilising sustainable fuels. This option could be imposed if stakeholders fail to reach an agreement on the power unit direction.
The FIA acknowledged that it identified potential energy management problems years ago. However, manufacturer agreements constrained the governing body from making significant changes without broad support.
Alongside the hybrid system, the 2026 regulations mandate the use of 100% sustainable fuels. This presents a substantial technical challenge for fuel manufacturers, aiming for performance comparable to fossil fuels.
The ongoing discussions involve Formula One Management, the FIA, teams, and manufacturers. A package for future power unit regulations is expected to be ready for discussion by the end of this year.
