Mercedes Dominates Final Day of Barcelona Test as Aston Martin's AMR26 Makes Brief Debut

Mercedes delivered a commanding performance on the final day of pre-season testing in Barcelona, with George Russell and Kimi Antonelli setting the fastest times. The session was also marked by the long-awaited, if brief, track debut of Aston Martin's new AMR26 car, which completed only a handful of laps before stopping on circuit.

Why it matters:

Mercedes has sent a powerful message to its rivals, demonstrating not just raw pace but also formidable reliability with a massive 168-lap haul on the final day. Meanwhile, the first glimpse of Adrian Newey's first design for Aston Martin, despite its troubled debut, is a significant milestone that sets the stage for the team's 2026 ambitions.

The details:

• Mercedes' Supreme Display: George Russell set the ultimate pace with a 1m16.641s, beating teammate Kimi Antonelli's earlier benchmark. The team completed a mammoth 168 laps, topping the overall mileage charts for the test and showcasing the W17's balance and reliability.
• Aston Martin's Arrival: After a delayed start to its test program, Aston Martin finally rolled out the all-black AMR26. Lance Stroll managed only a few installation laps and a single timed lap (1m46.404s) before the car stopped on track, causing a red flag near the session's end.
• Ferrari's Solid Run: Charles Leclerc, taking over from Lewis Hamilton in the afternoon, put Ferrari third on the timesheets. The team completed a respectable 170 laps on the day, with Hamilton contributing 85 despite a minor spin earlier.
• Mixed Fortunes Elsewhere: McLaren's running was cut short by a fuel systems issue for Oscar Piastri. Red Bull and Haas were absent, while Alpine, Audi, and Williams saved their running or were unable to participate.

What's next:

Pre-season testing has concluded, leaving teams with a final dataset to analyze before the season opener. Mercedes leaves Barcelona as the clear benchmark, while all eyes will be on Aston Martin to resolve the AMR26's early gremlins. The real test begins at the first race, where these early impressions will be put to the ultimate test.
