Sebastian Vettel has issued a warning to Formula 1 regarding the new 2026 regulations, suggesting that the changes could lead to a repeat of the mistakes made during the introduction of hybrid power units in 2014.
The 2026 season will mark a major technical revolution in Formula 1, with significant updates to chassis design, aerodynamics, and power units. One of the most debated elements of the new rules is the hybrid engine, which will generate half of its power from an electric component and the other half from a more efficient internal combustion engine running on sustainable fuel.
In theory, this shift toward sustainability should align perfectly with Vettel’s long-standing commitment to environmental causes. However, the four-time world champion has expressed skepticism about the effectiveness of the 2026 technical package.
“The new regulations don’t entirely convince me,” Sebastian Vettel told Auto Motor und Sport. “Recovering energy is a positive step, but doing it only from the rear axle while ignoring the front doesn’t make sense.”
Sebastian Vettel is concerned that Formula 1 could repeat the mistakes of 2014, when the first hybrid power units were introduced. The initial rules raised costs significantly without delivering substantial benefits to the teams or the sport as a whole. “The 2014 rules were good in principle, but the implementation wasn’t. They were too expensive and didn’t bring anything useful to the series,” he explained.
The German driver also criticized the increasing weight of modern Formula 1 cars, which reached 800 kilograms in 2025. “We are moving slightly in the right direction, but it’s just a drop in the ocean. The cars are too heavy. They should be at least 200 kilograms lighter,” Vettel added.
Looking at the future of the power unit, Sebastian Vettel stressed the importance of balancing innovation with cost control. “The current engines are far too expensive. There has been no technology transfer to road cars because the engines are too complex and costly. You need to ask: what do you want to achieve? How do you achieve it? And with what budget?”
Finally, Sebastian Vettel offered a broader warning about the very nature of Formula 1. “From a sporting perspective, the competition must be as close as possible without damaging the spirit of F1. And people need to be able to afford this sport,” he concluded.
For Sebastian Vettel, the 2026 regulations represent a pivotal moment. While they promise sustainability and technological progress, there is a clear need to ensure that costs remain manageable and that the sport retains its competitiveness and accessibility.
