Russell Impressed by Rival Reliability as Mercedes Logs 151 Laps in 2026 Shakedown

Mercedes successfully completed 151 laps on the opening day of the 2026 Barcelona shakedown, with George Russell praising the impressive reliability shown by rival teams. The session marked a stark contrast to the chaotic 2014 regulation changes, as teams like Red Bull and Haas logged significant mileage despite the introduction of new chassis and power unit rules.

Why it matters:

High mileage on the first day of a new regulatory era is a strong indicator of engineering stability and readiness. With the 2026 rules introducing major changes to both chassis and power units, avoiding early teething problems puts teams in an advantageous position to develop performance ahead of the season opener.

The details:

• Mercedes' Run: The Brackley squad split duties between Kimi Antonelli (56 laps) and Russell (95 laps), covering over 700 kilometers in the new W17 without major issues.
• Rival Reliability: Russell highlighted that Red Bull’s new power unit completed over 100 laps, a notable feat considering it is the first engine they have built independently. Haas also surpassed 150 laps, demonstrating the strength of the Ferrari power unit.
• Comparison to 2014: Unlike the difficult transition to V6 turbo-hybrids a decade ago, the current reset has been notably smoother, though new entrants Audi and Cadillac faced more complications during their debut runs.
• Schedule Adjustment: Mercedes will skip Tuesday’s running due to a forecast of rain, opting to focus on dry running conditions over their remaining allotted days in Barcelona.

What's next:

Teams will continue to analyze data from the shakedown to refine their packages for the season. While the initial reliability is promising, the focus will soon shift to extracting performance and fine-tuning the new aerodynamic concepts as the test days progress.
