Antonelli's Baku Shock: Championship Leader Stops After Nine Laps in FP1

Kimi Antonelli's Baku weekend got off to a rough start as the championship leader was forced to park his Mercedes after just nine laps in FP1. A hydraulics failure ended a session that had begun with the Italian topping the timesheets. George Russell set the benchmark for Mercedes while technical gremlins hit several teams.

Why it matters:

Antonelli's early exit is a blow for a driver chasing a first title, especially on a track where track time is at a premium. Reliability is a key concern as Mercedes looks to maximise its package in the closing stages of the season. With the field tightly packed, any lost running could prove costly.

The details:

• Antonelli led with 1:46.265, a tenth clear of Hamilton, before the hydraulics issue forced him to stop at an escape road.
• Russell's 1:45.387 was enough for P1, 0.4s ahead of Max Verstappen, with Charles Leclerc just 0.004s further back in third.
• Hamilton took fourth, while Antonelli's early time still left him fifth despite his limited running.
• Piastri reported heavy brake vibrations, while Verstappen and Hadjar also noted unusual brake behaviour. Sainz's Williams caught fire at the rear brakes.
• Hadjar's Red Bull required a power unit change after he reported an issue, leaving him last. Hülkenberg also stopped with a technical problem in his upgraded Audi.

What's next:

Mercedes will investigate the hydraulics failure ahead of FP2, with Antonelli needing a trouble-free session to build confidence on the street circuit. The team will hope the issue is isolated, as the championship leader can ill afford more lost track time in Baku.
