Red Bull challenges FIA engine benchmark verdict as Mekies demands talks

Red Bull has publicly challenged the FIA's ADUO findings that designated its 2026 power unit as the grid's benchmark internal combustion engine, with team principal Laurent Mekies revealing the squad sees no supporting data and is pressing the governing body for an urgent explanation. The verdict, handed down in Monaco, grants Mercedes one extra upgrade opportunity while Ferrari, Audi and Honda receive two—yet Mekies argues recent results across power-sensitive circuits show his team actually trailing Mercedes.

Why it matters:

If the FIA's assessment holds, Red Bull could watch its rivals unlock extra development allowances to close a gap the team insists does not exist. The clash highlights the difficulty of isolating pure engine performance from chassis and aerodynamic factors under F1's new power unit formula, threatening to scramble the competitive order through corrective measures aimed at the wrong target.

The details:

• The FIA's ADUO report evaluated ICE performance across the opening five grands prix and concluded Mercedes sat more than 2 per cent behind Red Bull, with Ferrari, Audi and Honda over 4 per cent adrift.
• Mekies told media Red Bull accepts the regulatory framework but cannot identify "one single data sample" that points to an ICE advantage over Mercedes.
• Track evidence: Citing Canada's high ICE power sensitivity, where Red Bull qualified sixth, versus Monaco's low sensitivity, where the car missed pole by just four hundredths, Mekies said the spread aligns with power sensitivity rather than superior engine output.
• Verstappen cautious: When asked if the ruling could tie Red Bull's hands, Max Verstappen declined to engage, simply replying, "I hope not."

What's next:

Red Bull is expected to push for deeper technical talks with the FIA in the coming days to scrutinise how the benchmark was calculated. With rival manufacturers already granted additional upgrade windows, the outcome could determine whether those teams gain a lasting edge—or if the governing body is forced to revisit a verdict Red Bull claims is fundamentally at odds with reality.
