McLaren team principal Andrea Stella questions whether Red Bull’s full engine change for Max Verstappen at the Brazil Grand Prix should count against the 2025 cost cap, seeking FIA clarification.
Verstappen qualified 16th, then took a complete power unit swap and started from the pitlane after exceeding allocations for ICE, turbo, MGU-K, MGU-H, and third energy store and control electronics.
Financial regulations exempt power unit supply costs up to €15 million. Additional components and related charges may interact with the cap, depending on the FIA’s interpretation.
Stella argues the change appears performance-led rather than fault-driven, and wants clarity on whether such a strategic swap should be accounted for under the cap.
“If the engine was changed for performance reasons, it should go in the cost cap,” Stella says.
He adds McLaren would avoid a similar move if it compromised budget headroom, reinforcing how cost governance now shapes race-weekend decisions.
Red Bull’s approach draws attention because Verstappen recovered strongly, with some rivals suggesting a fresh power unit aided overtakes, especially in low-grip phases.
Power unit supply is exempt up to €15 million, but performance-led component use could still affect cap accounting.
Stella counters that modern hybrid engines show minimal mileage-related performance drop, reducing the payoff from introducing new units purely for speed.
Penalties and starting position losses typically outweigh any marginal gain, he says, which is why teams usually defer changes unless reliability is at risk.
FIA guidance on how such swaps are costed will influence 2025 reliability plans and race-weekend trade-offs.
The question now sits with the FIA. A clear stance will determine whether performance-triggered engine changes become routine options or rare, budget-sensitive exceptions.
With teams preparing for 2025, rivals will track the outcome closely, aligning component usage, penalty risk, and financial headroom to preserve competitive flexibility across the season.
