Why Toto Wolff Thinks Some F1 Teams Will Struggle with 2026 Engines
The 2026 Formula 1 season promises to bring a whirlwind of changes, with new power unit regulations that could leave some teams playing catch-up. Mercedes' Team Principal, Toto Wolff, has thrown light on a potential disparity across the grid. According to Wolff, the innovative power units, which feature 100% sustainable fuels and a 50/50 power split between internal combustion and electrical components, may pose significant challenges for certain teams.
The 2026 Power Unit Paradigm
Set to debut in 2026, these power units mark a departure from the current technology by eliminating the MGU-H system and upping the ante on electrification. These futuristic engines are designed to be greener and more efficient, echoing the broader environmental goals of both the sport and the global automotive industry.
Wolff believes the journey to adapt to these new requirements might not be smooth sailing for everyone. He hints that while some teams are advancing like a well-oiled machine, others find themselves treading water. “On the power unit side, the ship has sailed,” said Wolff. “There are teams that feel they are on the back foot, and there are other teams, and OEMs, that feel they have done a good job.”

Since the 2026 power unit regulations were formalized in 2022, the debate has only intensified. Recent drafts of the chassis and aerodynamic regulations, revealed just before the Canadian Grand Prix, have triggered further scrutiny. Detractors argue that these new rules could be compromising the sport, sparking a need for adjustments. McLaren's Team Principal, Andrea Stella, echoes this sentiment, suggesting that the planned power unit usage still requires fine-tuning.
However, hope is not lost. FIA's Seater Director, Nikolas Tombazis, remains optimistic, confident that the engine manufacturers will step up to the plate if changes are necessary. “There’s, generally speaking, a very good spirit of collaboration. If there are some tweaks needed, I’m quite confident the PU manufacturers would help and be collaborative here,” said Tombazis.

Amidst this regulatory fray, Mercedes appears quietly confident. The team dominated the early hybrid era from 2014, and there’s a palpable sense that history could repeat itself in 2026. This confidence is not just top-down; it resonates through the entire team. In Monaco, George Russell shared his optimism, stating, “The team are feeling really confident for this era,” and noting that Mercedes is “in a really great place to have a great engine.”
With Mercedes yet to seize a Grand Prix victory since Sao Paulo in 2022, it’s no wonder the team is eager to leverage any potential advantages for the 2026 season and beyond. The German carmakers' bullish stance on their upcoming power unit further cements their intent to reclaim the top spot on the podium.
As teams continue to develop and refine their engines, only time will tell which of them will master the transition and who will falter. However, one thing is for certain: the 2026 season is set to be a pivotal point in F1 history, and for Mercedes, it might just be the start of another dominant era.
