Mercedes Dominates Long-Run Pace in F1 Spanish GP Practice

George Russell emerged as the fastest long-run driver carrying a heavy fuel load during Friday's practice sessions ahead of the Formula 1 Spanish Grand Prix. Red Bull's Max Verstappen was his closest challenger, trailing by just 0.13 seconds per lap after adjusting for tyre compounds and stint lengths, while world championship leader Kimi Antonelli ranked third, 0.55s behind Russell. Conversely, Ferrari and McLaren recorded disappointing race simulations, with Ferrari trailing Mercedes by around nine tenths of a second per lap, Oscar Piastri finishing 1.51s off the pace, and Lando Norris unable to complete a long run due to technical problems.

Telemetry data highlighted Mercedes' clear advantage in the final sector, driven by efficient battery management and top-speed performance. Over a single lap, the competition appeared closer, as Charles Leclerc could theoretically have logged the fastest lap of 1:33.478 by combining sector times, though only Arvid Lindblad managed to assemble all his best sector times into a single lap. In the midfield, Lindblad placed fourth in the second practice session before suffering a heavy crash that caused a red flag. Haas ultimately recorded the best long-run pace in the midfield as Esteban Ocon finished 0.92s per lap behind Russell, ahead of Alpine, Audi, Williams, Cadillac, and Aston Martin.

The new street circuit in Madrid also delivered unexpected insights regarding tyre behavior. Mercedes team principal Toto Wolff noted high tyre degradation despite initial struggles to bring tyres up to temperature, pointing to roughly three tenths of degradation per lap in the second practice session and suggesting a potential two-stop strategy. In contrast, Pirelli motorsport chief Dario Marrafuschi offered a differing assessment, stating that strong asphalt grip would likely result in lower degradation than expected. Further setup modifications are anticipated across teams ahead of Saturday's sessions on the new track.
