Lawson disqualified from Mexico City qualifying for MGU-K technical breach

Liam Lawson has been disqualified from qualifying for the Mexico City Grand Prix after stewards ruled his Racing Bulls car breached technical regulations, wiping out his eighth-place qualifying result. He had already carried a one-place grid penalty for his FP2 clash with Max Verstappen; he now drops to the back of the grid.

Why it matters:

The penalty removes a strong qualifying performance from the midfield fight and hands Racing Bulls a strategic headache—plus potential flexibility—before Sunday’s race. It also underlines how tightly F1 polices hybrid power delivery, where tiny overruns can invalidate a lap.

The details:

• The FIA technical delegate referred Lawson’s car immediately after qualifying, citing a breach of the minimum MGU-K power requirement just after he crossed the line on his fastest Q2 lap at 15:47:36.
• Stewards found the car contravened Articles C5.12.6 and C5.12.7: driver maximum power demand and ERS-K electrical DC power were reduced at greater rates than permitted.
• Lawson was summoned to the stewards, and his exclusion from qualifying followed shortly after.
• Because he has no qualifying result, he needs stewards’ permission to race on Sunday; that is routinely granted on free-practice times, so his participation is not in serious doubt.
• If Racing Bulls alter setup or change components, breaching parc fermé, he would start from the pit lane rather than the back of the grid.

What's next:

Either starting scenario would let Racing Bulls choose any tyre compound for the opening stint and fit power unit parts without the usual grid penalties—a tactic teams have used at high-altitude Mexico to run a long first stint on hards. The team now faces a clear trade-off: salvage track position or maximise strategic and component freedom.
