Kimi Antonelli’s Azerbaijan Grand Prix begins with an early setback as a suspected hydraulic fault stops his Mercedes during FP1 at Baku, 25 minutes into the session.

The Italian tops the timesheet on a 1:46.265 before smoke appears from the rear, prompting immediate radio reports of a hydraulic problem from the driver.

He parks at Turn 7 and exits safely. A marshal applies extinguisher spray around the rear bodywork. Despite heavy smoke from sidepod vents, no fire is evident.

The extinguisher use increases the subsequent clean-up requirements, and Antonelli assists marshals in rolling the car into the run-off area to expedite recovery.

Baku’s long straights, heavy braking, and tight traction zones stress hydraulics, cooling, and packaging. Such profiles can expose marginal temperatures, line pressure issues, or ancillary component weaknesses.

Mercedes must swiftly identify the fault source and containment, then complete rectification before the next running. The team’s ability to turn the car around will shape Friday’s baseline.

Antonelli arrived as the season’s championship leader by 81 points, making risk management and mileage preservation as critical as outright lap time this weekend.

Expect focus on hydraulic circuits, pump drives, seals, and associated cooling, alongside power unit and gearbox interfaces. Correlation checks will follow any component swaps or rebuilds.

Turnaround speed is vital with limited practice time. Mercedes has emphasized rapid response in support of its rookie, urging process discipline to resolve issues quickly.

Antonelli’s composure aligns with a season defined by minimizing damage on compromised days, mirroring his broader turnaround under pressure across 2026.

Others also report brake and technical niggles, underlining Baku’s punishing reliability demands. Small issues risk snowballing into significant grid penalties if component lifing is affected.

With the race set for September 26, attention turns to damage limitation and data capture. A clean FP2 would stabilize Mercedes’ weekend and protect Antonelli’s strategic options.

Provided the failure is contained, the early pace suggests the W17 remains competitive. Execution and reliability will likely decide how much of Friday’s promise converts into Sunday points.
