Red Bull Defends Verstappen Engine Swap as McLaren Seeks Cost-Cap Clarity

The dispute centers on whether performance-driven power-unit swaps fall within the financial limit, with a formal view possibly only emerging after next year’s audit.

Overview

  • After a Q1 exit in São Paulo, Red Bull started Max Verstappen from the pit lane and fitted a fresh Honda power unit alongside setup changes.
  • McLaren team principal Andrea Stella questioned whether a performance-motivated replacement should count toward Red Bull’s spending limit and asked for clarity.
  • Red Bull’s Paul Monaghan said the decision was legitimate and defendable, while declining to specify how the change is treated under the financial rules.
  • The Race reports the FIA has issued no formal determination and that any judgment may come when cost-cap submissions are reviewed next year.
  • McLaren’s Neil Houldey underscored customer-team constraints and pointed to 2026 power-unit cost-cap rules that are expected to reduce such ambiguity.
