George Russell emerged as the quickest driver in the opening practice session for the Azerbaijan Grand Prix, delivering a strong statement for the Mercedes team at the demanding Baku circuit. The British racer posted a leading time that was boosted by a substantial slipstream from fellow competitor Fernando Alonso, allowing him to outpace Red Bull’s Max Verstappen as well as both Ferrari entries by roughly four‑tenths of a second. Russell’s performance not only underscored his raw speed but also highlighted Mercedes’ ability to extract pace even on a street track known for its tight corners and long straightaways. The session, however, was marked by a significant setback for championship leader Kimi Antonelli.
The Italian rookie, who entered the weekend with an 81‑point cushion over Russell in the drivers’ standings and a comfortable margin of more than 100 points ahead of Lewis Hamilton and Lando Norris, was forced to retire after a hydraulic failure halted his car on track. The malfunction cost Antonelli approximately 35 minutes of valuable running time, leaving him at a disadvantage ahead of the second practice later on Thursday. Antonelli’s recent form has been impressive, having claimed victory in the previous two Grand Prix events.
Yet Baku remains one of the most unforgiving venues on the calendar, frequently producing unexpected drama and testing the reliability of even the most well‑prepared machines. With his lead now under threat, Antonelli and the Mercedes engineering crew will be keen to diagnose the cause of the hydraulic issue and ensure the car is fully operational for the remainder of the weekend.
Sky Sports F1 analyst Jamie Chadwick noted that the first practice session is often the least indicative of overall weekend performance, especially for a driver as dominant as Antonelli. She added that the real concern lies in the underlying reliability of the Mercedes platform. Earlier in the day, discussions had centered on the team’s improved reliability record over the past few races, but this incident could reignite worries about potential weak points that may emerge under the extreme stresses of Baku’s high‑speed sections.
Meanwhile, other front‑runners are also shaping up for a competitive weekend. Lewis Hamilton and Charles Leclerc each recorded their best lap times on the medium‑compound tyres, suggesting they will be serious contenders for pole position when qualifying commences on Friday. Their teams will be hoping to translate that pace into a strong grid slot and, ultimately, a shot at the race win on Saturday.
Red Bull, not to be outdone, introduced several new aerodynamic components for the Baku outing, including a revised floor, updated sidepods, and modified mirrors. Verstappen, who tested the hard tyre early in the session, appeared very quick, indicating that the upgrades may have paid off. When Russell’s slipstream advantage is removed from his fastest lap, the gap between the leading Mercedes and the Red Bull cars narrows, implying that the competition at the front will be tight. McLaren’s Oscar Piastri and Lando Norris found themselves in sixth and fourteenth positions respectively, both over a second off Russell’s pace despite having received aerodynamic upgrades aimed at improving performance on high‑speed circuits.
Piastri at one point suspected damage to his car, but the team reported no visible issues. Norris, meanwhile, has yet to reveal his full speed potential, leaving his weekend outlook uncertain. A notable storyline involves Isack Hadjar, who was confirmed to remain with Red Bull through the 2027 season. Hadjar returned to the track for the first time since July after missing three consecutive race weekends due to a wrist injury.
Unfortunately, he too suffered a setback, losing around 30 minutes of running after an engine problem curtailed his session. Liam Lawson, stepping into the Racing Bulls seat, made an immediate impression by launching from the start line into seventh place, with teammate Arvid Lindblad close behind in eighth. Their performance demonstrates the depth of talent within the Red Bull junior program and adds another layer of intrigue to the midfield battle.
Further down the order, Esteban Ocon, whose future with Haas appears uncertain as the team is expected to release him after this season, managed to secure ninth place. Audi’s Gabriel Bortoleto rounded out the top ten, showcasing the growing competitiveness of the newer entries.
Williams experienced a minor incident when Carlos Sainz’s car suffered a brief brake fire early in the session. The fire caused only a minimal loss of track time, and the team’s extensive upgrade package for the weekend remained largely unaffected.
The schedule for the remainder of the weekend is packed with action. Thursday will see the second practice session begin at 1 p.m., followed by the F1 Show at 2:15 p.m.
Friday’s agenda includes the F2 Sprint, the third practice session at 9:30 a.m., and the crucial qualifying session for the Azerbaijan Grand Prix at 1 p.m. Saturday will host the F2 Feature Race 2, the Grand Prix itself at noon, and post‑race analysis. All events will be broadcast live on Sky Sports F1 and Sky Sports Main Event, with streaming available via NOW without a long‑term contract.
In summary, Russell’s early speed, Antonelli’s reliability concerns, and the introduction of new parts by Red Bull set the stage for an exciting and unpredictable race weekend in Baku. Teams will be looking to fine‑tune their cars, manage tyre strategies, and avoid the pitfalls that have historically plagued this street circuit. The outcome of the qualifying session will be pivotal, as it could dictate the strategic approaches for the race and potentially reshuffle the championship battle as the 2026 Formula 1 season progresses.
