George Russell emerged as the quickest driver in the opening practice session for the Azerbaijan Grand Prix, while championship frontrunner Kimi Antonelli was forced to halt his run due to a hydraulic failure on the track. The British driver, who currently trails Antonelli by 81 points in the Drivers' Championship, must begin to close the gap to his teammate if he hopes to keep his title hopes alive, and his strong showing in Baku suggests he is ready to do just that.
Russell’s best lap was heavily aided by a powerful slipstream from Fernando Alonso, allowing him to carve out a four‑tenths advantage over Red Bull’s Max Verstappen and both Ferraris. Even before that decisive lap, the Mercedes driver displayed impressive pace throughout the session, consistently running among the top times and signalling that his car is well‑balanced for the high‑speed, low‑downforce layout of the Baku street circuit.
Antonelli, on the other hand, lost a staggering 35 minutes of track time when a hydraulic issue forced him to pull into the pits. The setback means the Italian will head into the second practice session later on Thursday with a clear disadvantage, needing to make up lost time while also addressing the reliability concern that has suddenly surfaced.
Although Antonelli has claimed victory in the previous two races, Baku is notorious for its demanding combination of long straights and tight corners, often producing unexpected drama that can quickly erode even the largest points leads. His current 81‑point cushion over Russell and more than a 100‑point buffer ahead of Lewis Hamilton and Lando Norris could be under threat if the hydraulic problem proves systemic.
"FP1 is the least representative session for Kimi," noted Sky Sports F1 analyst Jamie Chadwick, "so in that sense it’s a blessing for him. The bigger worry is why the issue occurred. We’ve heard reliability being a hot topic for Mercedes earlier in the weekend, but they seemed to have sorted it in recent races.
This could become the main concern moving forward." Meanwhile, Lewis Hamilton and Charles Leclerc each set their quickest times on the medium‑compound tyres, positioning themselves as potential front‑runners for Friday’s qualifying and the race on Saturday afternoon. Red Bull, not to be outdone, introduced a suite of new aerodynamic components for Baku, including a revised floor, updated sidepods, and redesigned mirrors. Verstappen showed early speed on the hard tyres, hinting that the Dutchman could be a serious contender despite the modifications. If you strip away the slipstream advantage that helped Russell on his fastest lap, the picture remains clear: Red Bull, Mercedes, and Ferrari are all locked in a tight battle for supremacy at the front of the grid.
McLaren’s Oscar Piastri and Lando Norris found themselves in sixth and fourteenth places respectively, more than a second off Russell’s best time even after receiving aerodynamic upgrades aimed at improving performance on high‑speed circuits. Piastri at one stage suspected he had sustained damage to his car, but the team reported no visible issues, while Norris has yet to unleash his full potential. Red Bull’s rising star Isack Hadjar, confirmed to remain with the team through 2027, returned to the garage for the first time since July after missing three consecutive race weekends due to a wrist injury. Unfortunately, he also suffered a 30‑minute loss of running because of an engine problem, compounding his limited track time.
This development opened the door for Liam Lawson, who stepped back into the Racing Bulls lineup and launched from the start line in seventh place, with teammate Arvid Lindblad close behind in eighth. Further down the order, Esteban Ocon, whose future with Haas looks uncertain as the team is expected to release him for the 2027 season, managed to secure ninth place, while Audi’s Gabriel Bortoleto rounded out the top ten in tenth. Williams driver Carlos Sainz experienced a minor brake fire early in the session; however, the incident cost him little time and the team has introduced a significant upgrade package that could prove decisive later in the weekend.
The schedule for the weekend is packed: Thursday sees the continuation of practice at 1 pm, followed by the F1 Show at 2:15 pm. Friday’s agenda includes the F2 Sprint at 5:10 am, the third practice session for the Grand Prix at 9:30 am, the F2 Feature Race, and finally the crucial qualifying session for the Azerbaijan GP at 1 pm.
Saturday will host the second F2 Feature Race in the morning before the Grand Prix itself kicks off at noon, with post‑race analysis and reaction segments scheduled throughout the afternoon. All events will be broadcast live on Sky Sports F1, with streaming available via NOW without a long‑term contract.
In summary, Russell’s early dominance, Antonelli’s unexpected mechanical gremlin, and the aggressive development work from the front‑running teams set the stage for a thrilling Baku weekend. With the championship still wide open, every point earned in the practice sessions could prove vital as drivers and engineers alike fine‑tune their machines for the high‑stakes showdown on the streets of Azerbaijan.
