      Formula 1 is contemplating a strategy to reintroduce 'green' normally-aspirated V10 engines to the grid sooner than expected. Next year, the series is set to transition from its current 2014-2025 'hybrid power unit' era to even larger and more electrified turbo V6 engines. However, the thrilling prospect of loud, lightweight, straightforward, fan-favorite V10s fueled by 100 percent sustainable fuel has led to a "contingency plan for the future" quietly developing over the past few weeks, as reported by Auto Motor und Sport. Correspondent Michael Schmidt mentioned that one proposal involves postponing the 2026 engines, which are currently being vigorously developed, for two years—allowing a shift to the 'green' V10s in 2028. "Even at an experienced stage of development, some teams have indicated that the 2026 regulations are overly ambitious," he stated. They reportedly contend that the possibility of certain cars operating at significantly reduced speeds to recover energy raises "safety concerns" regarding crashes. "Many are also worried that the show might diminish," added Schmidt. He noted that a "V10 working group" has been established. An unnamed insider remarked, "The manufacturers exerting the most pressure on the teams to make this happen are those who already recognize they're trailing with their 2026 engine." Red Bull and Ferrari reportedly back the V10 concept, while Honda, Audi, and Mercedes oppose the idea of delaying the 2026 engines for an additional two years. Team boss Toto Wolff argued, "We simply don’t have enough current engines." An alternative plan under consideration is to allow the 2026 advancements to continue but limit them to just three years instead of five—introducing the V10s afterward.
