Mercedes shines in 2026 F1 shakedown with impressive reliability

Mercedes has emerged from the first private shakedown of the 2026 Formula 1 season in Barcelona with high confidence, buoyed by exceptional reliability and mileage that has backed up rumors of a class-leading power unit. Engineering Director Andrew Shovlin declared the three-day test "couldn't have gone any better," as the team completed a race simulation and a combined 183 laps in a single day with drivers Andrea Kimi Antonelli and George Russell.

Why it matters:

After four difficult seasons under the previous ground-effect regulations, Mercedes is determined to reclaim its dominant position with the new 2026 rules reset. This early demonstration of reliability and performance is a crucial morale boost and signals serious intent, positioning the team as the early favorite with bookmakers for the constructors' championship based on its history of mastering major regulation changes.

The details:

• The Barcelona shakedown was the first on-track running for the all-new 2026 chassis and power unit regulations, with Mercedes utilizing its maximum allowed three days of running.
• On Wednesday, rookie Andrea Kimi Antonelli successfully completed a full race simulation in the W17, sharing the car with George Russell. The pair's 183 laps in one day helped Mercedes log the most mileage of any team during the test week.
• Andrew Shovlin highlighted the team's energy and progress, noting that initial challenges were quickly addressed, making the car quicker day by day.
• Reliability as a Strength: Shovlin singled out the car's "amazing" reliability as a "huge testament" to the work at the team's Brackley and Brixworth factories, directly supporting paddock rumors that the Mercedes power unit is currently the benchmark in F1.
• The test took place in cool January conditions at the Circuit de Barcelona-Catalunya, which Shovlin acknowledged is not representative of typical race temperatures the team will face later in the year.

What's next:

The real work begins at the official pre-season tests in Bahrain in February, where conditions will be more relevant.

• Mercedes will shift focus to setup exploration and verifying that the car performs optimally at proper operating temperatures, both for chassis performance and system efficiency.
• The final Bahrain test will be dedicated to race preparation, including qualifying simulations and race procedure rehearsals.
• The 2026 season officially kicks off with the Australian Grand Prix in March, starting a record 24-race calendar. While encouraged, Shovlin and the team are not getting carried away, viewing the successful shakedown as merely the first positive step on a long road back to the front.
