F1 Azerbaijan GP: George Russell tops FP1 as Kimi Antonelli suffers Mercedes trouble

Russell Leads Mercedes 1-2 as Verstappen and Leclerc Chase

George Russell set the pace in the first free practice session for the Formula 1 Azerbaijan Grand Prix, delivering a benchmark 1m45.387s on soft tyres with 20 minutes remaining to secure top spot for Mercedes. The Briton’s final effort edged out Max Verstappen’s Red Bull by a comfortable margin, while Charles Leclerc placed third for Ferrari to round out a tightly contested leading trio. The session, held on Thursday ahead of Saturday’s race to accommodate a national holiday, began cautiously on the dusty Baku city circuit, which sees Formula 1 action only once per year.

Antonelli Hydraulic Failure Triggers Early Virtual Safety Car

The session’s first major incident arrived before the halfway mark when championship leader Kimi Antonelli ground to a halt at Turn 7 with smoke billowing from his Mercedes W17. “a hydraulic issue,” the 20-year-old Italian reported over team radio, prompting a virtual safety car period while marshals cleared the car without requiring a red flag. The failure cost Antonelli valuable track time on a circuit where every lap counts, and he ultimately settled for fifth in the classification despite having briefly topped the timesheets with a 1m46.265s on harder rubber earlier in the hour.

Upgrade Packages Debut as McLaren, Williams, and Audi Seek Gains

Thursday’s running served as a critical shakedown for several significant technical updates. McLaren introduced new sidepods, a revised floor edge, and an updated diffuser aimed at addressing the MCL39’s low-speed weakness, though Oscar Piastri and Lando Norris endured a messy session—Norris languished in 14th without a representative soft-tyre lap as both cars underwent damage checks. Williams debuted its long-awaited package featuring a redesigned floor and lighter chassis, but brake overheating limited Carlos Sainz’s mileage. Audi’s upgraded machinery proved immediately competitive, with Nico Hulkenberg and Gabriel Bortoleto both reaching the top ten and displacing the Williams duo.

Red Bull Brake Concerns and Rookie Impressions

Verstappen reported early that “the brakes on his RB22 were pulling,” a concern echoed by returning team-mate Isack Hadjar, who also grappled with an apparent power unit issue on his first appearance since a wrist fracture sidelined him for three weekends. Verstappen briefly jumped to the top of the order with a rapid lap before Russell responded, though the Dutchman locked his fronts at Turn 1 and used the escape road on his subsequent push. At Racing Bulls, Liam Lawson returned to form in seventh ahead of rookie Arvid Lindblad, whose late spin at Turn 7—combined with Hulkenberg’s Turn 4 issue—brought out a second virtual safety car in the closing minutes.

Why This Matters

The Azerbaijan Grand Prix’s unusual Thursday-to-Saturday schedule compresses preparation time, making FP1 data disproportionately valuable for teams validating upgrades on a unique street circuit. Russell’s strong showing suggests Mercedes’ recent development direction is paying dividends on low-speed layouts, while Antonelli’s reliability setback underscores the fragility of his championship lead. McLaren’s aggressive update suite signals their intent to arrest a recent performance slide, and Audi’s immediate competitiveness with Hulkenberg and Bortoleto hints at a potential midfield shake-up. With track evolution rapid on the dusty Baku surface, Friday’s second practice—held under representative evening conditions—will be critical for tyre degradation analysis and race simulation ahead of Saturday’s grand prix.
