Leclerc Tops Timesheets as Alonso's 2026 Car Debut Highlights Barcelona Testing

Charles Leclerc set the fastest time on the final day of pre-season testing in Barcelona, but the spotlight was firmly on Fernando Alonso's first public run in Aston Martin's Adrian Newey-designed 2026 car. While Ferrari showed improved pace, closing to within two-tenths of Mercedes's benchmark, Alonso's limited-speed shakedown of the highly anticipated AMR26 generated the most intrigue.

Why it matters:

Pre-season testing offers the first, albeit fragmented, glimpse of a team's potential for the upcoming campaign. Alonso's debut in the new car, coupled with Ferrari's apparent step forward in pace, provides early clues about which teams may have made significant progress during the off-season and who might challenge the established hierarchy when the real competition begins.

The details:

• The final shakedown day saw eight teams take to the Circuit de Barcelona-Catalunya, with Williams absent as previously announced.
• Leclerc's Pace: After Ferrari initially appeared off the pace, Leclerc improved significantly in the SF-26, eventually posting a 1:16.653. This was just 0.2 seconds shy of George Russell's overall testing benchmark set earlier in the week.
• Alonso's Focused Run: Fernando Alonso completed his first laps in the new Aston Martin AMR26, a car designed by the newly recruited Adrian Newey. Reports indicated his running was under a speed limit (230-275 km/h), focusing on system checks and the new Honda power unit rather than outright pace. He finished the morning seventh fastest.
• Busy Track: Max Verstappen, back in the Red Bull after a two-day wait for parts, was the busiest driver early on. McLaren's Oscar Piastri also showed strong pace, briefly leading the times before being eclipsed by Leclerc.
• Morning Session Results: Leclerc led Piastri and Verstappen in the unofficial times. Oliver Bearman (Haas) and Pierre Gasly (Alpine) rounded out the top five, with Valtteri Bottas (Sauber) completing the fewest laps.

What's next:

The curtain closes on official pre-season testing, leaving teams with a wealth of data to analyze and final upgrades to implement before the season opener. The true competitive order will only be revealed under the pressure of qualifying in Bahrain, but the Barcelona test has set the stage for what could be a fascinating and unpredictable 2026 Formula 1 season.
