The German team is going all-in on a brand-new car after years of structural mistakes during the ground-effect era.

The lesson Mercedes needed before 2026

In Formula 1, every regulation change reshuffles the competitive order, and 2026 promises a major shake-up with new engines and chassis. Mercedes, which dominated much of the previous decade, knows exactly what it means to misread a rulebook from the start. Their first ground-effect car, the W13, was bold in concept but burdened by fundamental design flaws that affected three full seasons. That’s why the team has now chosen an aggressive strategy: focusing almost entirely on the 2026 car, even if that means sacrificing development for 2025.

The key: starting on the right foot under a new rule set

Trackside Engineering Director Andrew Shovlin made it clear: success in a new technical cycle depends on how you start. Mercedes learned that lesson the hard way in 2022, when a flawed aerodynamic and suspension interpretation forced them to chase Red Bull from behind. “We couldn’t fall again into the temptation of wasting resources on a late update,” said Shovlin. While the team still fights for P2 in the Constructors’ Championship, the factory has shifted almost all its focus to 2026, a move their closest rivals have also mirrored.

When theory doesn’t match reality

The W13 was built around a floor concept that only worked at extremely low ride heights, paired with an overly stiff suspension. The result: porpoising, bouncing and an unpredictable chassis, problems that grew worse the more they tried to fix the concept. Mercedes eventually abandoned their radical zero-pod idea, realising late, but in time to learn that bouncing and porpoising were different yet related phenomena requiring distinct solutions.

Resetting a concept… and losing ground

Shovlin admitted that, with hindsight, it would have been “very easy” to avoid falling into that conceptual trap had they known what they know now. The constant changes in philosophy especially the complete redesign of the sidepods, acted as a development reset, while Red Bull, competitive from day one, continued evolving uninterrupted. In F1, a flawed concept doesn’t just make you slow: it forces you to spend resources re-engineering the very fundamentals you once thought were correct.

2026: the chance to start over

Mercedes approaches the next era with a very different strategy: building their car around a deep understanding of how the chassis, suspension and floor must work under the new regulations. After years of learning “the hard way,” the team is confident about starting with a stable, balanced platform and a clear development path. If execution matches theory, 2026 could be the season that brings the Silver Arrows back into title contention a goal that seems distant today, but one that may become reality thanks to the lessons learned from past mistakes.
