Verstappen Reacts to F1 Power-Unit Regulation Shift and ADUO Decision
6/12/2026, 10:04:54 PM
Background: 2026 Hybrid Power-Unit Overhaul
The 2026 season introduced a new V6-hybrid turbo power unit with an almost 50-50 split between internal-combustion (ICE) and electric output. Drivers, especially Max Verstappen, criticised the balance, calling the package “Formula E on steroids.” The controversy prompted a review by the FIA and the F1 Commission.
New Power-Unit Split & ADUO System
In June 2026 the FIA announced a compromise on the power-unit formula. The ICE-to-electric ratio will move to 58 % / 42 % for 2027 and to 60 % / 40 % for 2028, pending ratification by the World Motor Sport Council. Simultaneously, the Additional Development and Upgrade Opportunities (ADUO) system ranked manufacturers by performance. The FIA document placed Red Bull Powertrains as the benchmark, granting it no upgrade, while Mercedes, only 2 % behind Red Bull, receives one upgrade for 2027. Ferrari, Audi and Honda, each >4 % behind Red Bull, receive two upgrades. The decision was approved by a super-majority vote of the F1 Commission.
Verstappen’s Public Response
Speaking on Media Day at Barcelona, Verstappen welcomed the direction of the changes but expressed disappointment that the 60 % ICE target would not arrive until 2028. He noted, “Of course I would have hoped next year would be what we get already in 2028,” and added, “At least the changes they are making are heading into the right direction. So that’s a good thing.” He also said Red Bull’s power-unit performance surprised him, stating, “We just feel surprised, because we don’t feel like we are the best,” and described the team’s work as “super impressive.”
Other Drivers’ Views
Two-time champion Fernando Alonso argued that the underlying “DNA” of the regulations still rewards slower cornering for higher straight-line energy, saying, “You can make a small tweak on the rules, but it will always reward to go slower in the corners to have more energy on the straights.” Alonso concluded that the rules “need to be changed” because “there was something wrong from the beginning.”
Official FIA Statements & Findings
The FIA confirmed that the power-unit split adjustment and ADUO allocations are provisional, awaiting formal endorsement by the World Motor Sport Council. The organization emphasized that the ADUO rankings are based on measured performance gaps: Mercedes > 2 % behind Red Bull, Ferrari/Audi/Honda > 4 % behind. Red Bull, as the benchmark, will not receive an upgrade under the current framework.
Criticism & Opposition
Ferrari’s concerns centred on the ADUO system, fearing it entrenches Red Bull’s advantage. Audi and Honda opposed the hardware-intensive step-change, citing the financial burden of rapid development. Alonso’s comments reflect broader driver scepticism that the regulatory tweak does not address the fundamental performance balance.
Conflicting Reports & Gaps
Sources differ on Verstappen’s exact phrasing of the “minimum” ratio, with some quoting him as hoping for a 60 % ICE split in 2027, while the final agreement sets 58 % for that year. The ADUO document’s performance percentages are reported by Sky Sports but have not been released in an official FIA press release, leaving a verification gap.

- “At least the changes they are making are heading into the right direction. So that’s a good thing.” — Max Verstappen
- “We just feel surprised, because we don’t feel like we are the best,” — Max Verstappen
- “You can make a small tweak on the rules, but it will always reward to go slower in the corners to have more energy on the straights.” — Fernando Alonso, two-time world champion
- “Sky Sports News has seen the document which states Mercedes are more than two per cent behind Red Bull's power unit, so will be given one engine upgrade this year, while Ferrari, Audi and Honda will be given two upgrades as they are deemed to be more than four per cent adrift of Red Bull.” — FIA ADUO document (as reported)
- “I think Mercedes still has maybe as good an engine - it's very, very close between them - but it's not my decision at the end of the day.” — Max Verstappen
What’s Next
The FIA World Motor Sport Council is slated to ratify the split and ADUO framework before the season’s end. Red Bull will continue discussions with the FIA to clarify its ADUO status, while Verstappen’s contract outlook remains tied to the pace of regulatory evolution. The Barcelona-Catalunya Grand Prix will serve as the first on-track test of the revised power-unit balance.
