Wolff denies Mercedes has power unit advantage over customer teams

Mercedes team principal Toto Wolff has firmly rejected suggestions that the works team holds a hidden performance advantage with its power unit, insisting identical hardware is supplied to all customer teams despite a significant performance gap at the Australian Grand Prix. The disparity has been attributed to execution and mastery of the complex new 2026 energy management systems, not unequal equipment.

Why it matters:

In the new 2026 regulatory era, where electrical energy accounts for roughly half of a car's output, how a team manages its power unit is a decisive performance differentiator. Allegations of an unfair works-team advantage could undermine the credibility of F1's customer-supplier model and create tension within the Mercedes engine camp, which includes McLaren, Williams, and Alpine.

The details:

• The debate ignited after the Australian GP, where Mercedes locked out the front row and won, while its customer teams struggled to match their pace despite using the same power unit.
• Analysis pointed to superior energy deployment and harvesting strategies by the Mercedes works team as the key differentiator.
• Wolff attributes the performance gap to the steep learning curve of the new regulations, stating that integration through strategy, software, and driving style creates significant on-track variation.
• He emphasized Mercedes's commitment to providing equal hardware and support, stating the goal is to "provide a good service" to all customer teams.
• Driver George Russell supported this view, noting that last year McLaren beat Mercedes with the same engine, and now the situation is reversed, calling it part of the competitive "game."

What's next:

The focus now shifts to how quickly customer teams like McLaren and Williams can unlock the full potential of their Mercedes power units through better integration and energy management. As teams progress up the development curve, the performance gaps seen in Melbourne are expected to fluctuate throughout the season, testing Wolff's assertion that success hinges on execution, not exclusive equipment.
