Wolff cautions against switching to V8 engines 'too soon'.

      "Most manufacturers are not willing to finance a dual program."

      Toto Wolff has stated that Formula 1's anticipated shift back to V8 engines should not lead to soaring costs. FIA president Mohammed Ben Sulayem has been advocating for the introduction of the new engine regulations in 2029, but Mercedes team principal Wolff believes that such a timeline is unrealistic. "Most manufacturers don’t want to pay for a double program," Wolff mentioned. "Introducing a new engine in two years would lead to skyrocketing expenses," he was quoted as saying by Sport1.

      While all stakeholders generally agree that the post-2026 regulations will involve 2.4-litre V8s with hybrid support and sustainable fuel, the discussion revolves around the timing of the changes. Audi and Honda are resisting an early transition, opting to fully implement the upcoming electric-dominant 2026 rules. Sauber team principal Jonathan Wheatley, whose team will become Audi's works team next year, emphasized the manufacturer's viewpoint. "Audi is founded on three pillars - highly efficient combustion engines, advanced hybrid technology, and sustainable fuel. That will not change anytime soon."

      Mercedes and Ferrari have proposed a middle ground: to move the already planned 2031 regulatory change up by one year. "We all want thrilling regulations that captivate fans," Wolff stated. "The V8 with high revs, energy recovery, and e-fuel is perfect for that. But not at any cost."

      Ferrari team principal Frederic Vasseur concurred that the sport should not act hastily. "The 2026 engines haven’t even been tested yet. We don’t need to make a decision today or tomorrow," the Frenchman remarked. A meeting in London regarding this matter, which was set for this week, has been postponed indefinitely following the Italian GP weekend.
