Andrea Stella: "Very dramatic" Australian GP qualifying "exposes weaknesses" of 2026 F1 rules

F1 Australian Grand PrixFormula 1

McLaren Formula 1 team principal Andrea Stella thinks Melbourne's Albert Park circuit "definitely exposes some of the weaknesses" in the 2026 regulations as drivers voiced fierce opposition to the new power unit regulations.<br>The new 2026 rules force drivers to heavily compromise their driving style to focus on electric energy saving.

2026 Power Unit Regulations

Chapter: Chapter II - Power Unit Changes

In Simple Terms

2026 brings major engine rule changes. The complex MGU-H is removed to cut costs and attract new manufacturers. To compensate, the MGU-K becomes much more powerful and the battery is bigger. The goal is simpler, more sustainable power units that are still cutting-edge.

MGU-H removed from power units
MGU-K power increased significantly
Larger energy store capacity
Aims to attract new manufacturers

Official FIA Text

For 2026, the power unit will comprise a 1.6 litre V6 turbocharged internal combustion engine with a significantly enhanced electrical component. The MGU-H will be removed. The electrical power output will increase substantially with a more powerful MGU-K and larger energy store.

ERS-K Absolute Electrical Power

Chapter: C5

In Simple Terms

The ERS-K (kinetic energy recovery system) is the hybrid power unit that harvests energy from braking. F1 regulations cap the maximum electrical power this system can produce at 350kW to maintain competitive balance and prevent any team from gaining an unfair advantage through excessive hybrid power.

ERS-K electrical power output is strictly limited to a maximum of 350kW
This applies to the absolute DC electrical power measurement of the kinetic energy recovery system
The limit ensures all teams operate within equal technical parameters for the hybrid system
Exceeding this power threshold would constitute a technical regulation breach

Official FIA Text

Absolute electrical DC power of ERS-K may not exceed 350kW.

ERS-K Harvesting Limits

Chapter: C5

In Simple Terms

F1 cars can harvest a maximum of 8.5 megajoules of energy per lap from their braking system (ERS-K). The FIA can reduce this limit to 8MJ or 5MJ if needed, and teams can harvest an extra 0.5MJ under certain special conditions.

Standard ERS-K harvesting limit is 8.5MJ per lap
FIA can reduce the limit to 8MJ or 5MJ based on their determination
Up to 0.5MJ additional energy can be harvested under specified conditions
This energy comes from the car's braking system during each lap

Official FIA Text

Energy harvested by ERS-K must not exceed 8.5MJ in each lap. May be reduced to 8MJ or 5MJ depending on FIA determination. Up to 0.5MJ additional energy may be harvested per lap under specified conditions.
