Kimi Antonelli completed a clean sweep of Friday practice for the Austrian Grand Prix, setting the fastest time in both sessions to underline Mercedes' early dominance at the Red Bull Ring. The Italian, who leads the drivers' championship, clocked a 1:07.014 in the afternoon FP2, improving on his morning benchmark by nearly eight-tenths of a second. Oscar Piastri and Lando Norris followed in second and third for McLaren, the only team to consistently match the Silver Arrows' pace, while Max Verstappen and Lewis Hamilton rounded out the top five, half a second adrift.

The day unfolded in contrasting conditions. FP1 saw a Mercedes one-two, with George Russell just 0.040 seconds behind his teammate, but the Briton slipped to sixth in the later session after spending part of it in the garage for repairs. McLaren's challenge grew as the track rubbered in: Piastri briefly led FP2 on soft tyres before Antonelli responded with two successive improvements. Norris, the reigning world champion, survived a spin at Turn 3 to claim third. Red Bull, running a significant upgrade package including a new rear wing, could not break into the top three, while Ferrari's Hamilton and Charles Leclerc – the latter returning after handing his car to a rookie in FP1 – finished fifth and eighth, respectively.

Mechanical gremlins defined the afternoon for Cadillac. Sergio Pérez stopped on track in FP1 with an electronic control unit failure, triggering a red flag, and the same fault recurred on his out-lap in FP2, leaving the Mexican without a timed lap. His teammate Valtteri Bottas fared little better, completing only six tours before a suspected suspension issue caused the floor to drag and sparks to fly, forcing an early end to his running. Alpine's Franco Colapinto, eighth in the morning, slumped to 16th in FP2 after the team's new front wing failed to deliver the expected step in performance. “It didn't work as we expected,” the Argentine said, describing the lack of progress as “quite frustrating.”

Viewed from the paddock, the results reinforce the sense that Mercedes holds a narrow but real advantage heading into the weekend, with McLaren poised to exploit any weakness. The short, undulating Spielberg circuit, baking under 49°C track temperatures, placed a premium on mechanical reliability and tyre management, areas where several midfield teams struggled. With Antonelli holding a 41-point championship lead over Hamilton, Saturday's qualifying session – preceded by a final practice hour – will determine whether the Italian can convert practice pace into a critical pole position.
