Why Controversial F1 Rules Spark Widespread Discontent
Senior technical meetings have started to reassess F1’s 2026 regulations after only three races. The session began last Thursday and will continue through the month.
Rule changes are expected before the season resumes in Miami in May. Qualifying is the most likely area to see immediate adjustment.
Origins of the 50/50 powertrain
The shift toward a near 50/50 split between internal combustion and electric power began to be discussed in 2020. FIA technical director Gilles Simon described electrification as a major focus that year to Filmogaz.com.
Engine talks accelerated through late 2020 and 2021. CEOs from established and potential new manufacturers joined discussions.
Key technical decisions
The MGU-H was removed from the hybrid architecture. That decision aimed to cut complexity and attract new entrants.
The MGU-K was uprated to 350 kilowatts of peak power. Combustion output was reduced to about 400 kilowatts.
| Component | Peak power |
|---|---|
| MGU-K | 350 kW |
| Internal combustion engine | ≈400 kW |
Manufacturer influence and new entries
A primary objective was to attract more carmakers. By that measure, the rules achieved success.
- Audi committed to join under the new rules.
- Ford partnered with Red Bull Powertrains in 2023.
- Honda reversed its withdrawal and built a new 2026 engine.
- General Motors began a programme for 2029, enabling Cadillac to join.
Markus Duesmann said Audi saw Formula 1 as aligned with sustainability goals. Jim Farley framed Ford’s involvement as a way to promote EVs.
Numbers and context
Three brand-new manufacturers entered or engaged this decade. Honda also recommitted. Those additions changed the championship’s commercial and technical balance.
Without new manufacturers, the field risked being dominated by only a few engine suppliers.
Operational problems on track
The headline 50/50 split reflects peak capability. It does not mirror power delivery across a lap.
Batteries lack capacity to supply the MGU-K continuously. Charging rules then encourage lifting and coasting and so-called super clipping tactics.
The FIA reduced the lap charging limit from 9MJ to 8.5MJ. That cut was made because extreme harvesting tactics were already anticipated.
Start performance and turbo lag
Audi’s engine package has struggled at race starts. Teams report pronounced turbo lag without the MGU-H.
Mattia Binotto said Audi did not demand the 50/50 split. He also indicated Audi would not oppose adjustments to the ratio.
Christian Horner warned in 2023 about bizarre charging techniques and complex driving aids. His concerns were among the earliest public criticisms.
Current fixes and limits
Officials aim to tweak qualifying rules and energy deployment settings. Changes under consideration include super clipping thresholds and harvesting parameters.
Ferrari boss Fred Vassar warned any change will shift the pecking order. Small tweaks will not remove the core architecture.
Adjustments may ease the worst problems in qualifying. But the fundamental 50/50 design remains in place for now.
Symptom treatment versus structural change
Many insiders believe the package treats symptoms, not the root cause. The 50/50 architecture imposes intrinsic constraints.
That reality helps explain the controversial F1 rules and the widespread discontent among teams and fans. Meetings this month will test how much can be fixed without undoing the manufacturer gains of the last years.
