Mercedes has revealed that the initial 2026 Formula 1 pre-season test in Barcelona surpassed even their highest expectations. Over three days at the Barcelona-Catalunya circuit, drivers George Russell and Kimi Antonelli completed exactly 500 laps during Mercedes-led testing, placing the Silver Arrows at the top of the mileage charts in this closed-door session.
Not only were they the most active team on track, but Mercedes also showcased impressive speed, with both drivers setting new benchmark lap times throughout the testing period. Russell’s fastest lap of 1:16.445 on day four remains the quickest time of the five-day test, surpassing Mercedes’ best lap from last year’s Spanish Grand Prix.
Mercedes dominated the leaderboard by finishing first and second on both Wednesday and Thursday. However, it’s widely acknowledged that outright lap times during pre-season tests should be taken with caution, due to the many unknown variables and the secretive nature of this Barcelona shakedown.
What stood out most was Mercedes’ remarkable reliability and high mileage, drawing attention from rivals. On day two, Antonelli successfully completed a full race simulation. Testing proceeded smoothly, allowing Mercedes to focus on qualifying mode strategies on the final day, while other teams continued shakedown runs concentrating on reliability, system checks, and adapting to the new 2026 regulations.
Andrew Shovlin, Mercedes’ trackside engineering director, commented: “It’s been a strong week for us regarding reliability. The car enabled us to follow our planned program across all three days, just as we hoped upon arriving in Barcelona.” He added, “This success reflects the hard work from everyone at Brackley and Brixworth in developing this car. We’re also making good progress addressing issues identified earlier in testing, which is encouraging.”
Shovlin also noted that their focus has solely been on validating the W17 in Barcelona. “In Bahrain, we’ll shift our attention to setup exploration, but due to the cold conditions here, that wasn’t feasible. This approach will provide better insight into how the cars compare as we head into the 2026 season.” Additionally, Mercedes benefits from extensive data thanks to two of its customer teams, McLaren and Alpine, who are running the new Mercedes HPP power unit in their cars.
Mercedes was already considered a top contender for the 2026 championship before any on-track action, and their strong performance in Barcelona only bolsters that outlook among many observers.
Fan Take: This news is exciting for racing fans because Mercedes’ dominant and reliable showing early on signals they could set the benchmark for performance in 2026. If they maintain this level of excellence, it could shape the competitive dynamics of F1 and push other teams to innovate even harder.
