Sebastian Vettel warns of 2014 repeat as parts of 2026 regulations "don't make sense"

Four-time Formula 1 world champion Sebastian Vettel has raised his concerns over the regulation changes coming into play in 2026. In a comparison to 2014, the now-retired F1 driver has criticised the plans soon to come into effect.

The 2014 season saw one of the most substantial changes to regulations in the championship's history with the introduction of highly complicated and expensive hybrid powertrains. With F1 looking to run more parallel to road car technology and promote a more environmentally friendly brand, the target was fuel efficiency. 

But with this change came great costs as well as a highly imbalanced grid. Mercedes boasted a massive advantage, winning 16 of the 19 races in 2014 and eight constructors' championships from then to 2021. 

“The 2014 regulations were good in principle," Vettel told Auto Motor und Sport. "The idea behind them was sound. But the implementation wasn’t right. It cost far too much money and didn’t bring anything to the series.”

The 2026 regulations bring even further changes to the powertrain, with 50% of power now coming from electrical energy. While the cars will be lighter by 30kg and feature more efficient aerodynamics, the overall concept of the changes is still an issue, according to the former Red Bull driver.

“Innovative solutions from the previous engine regulations are being dispensed with in order to make it less expensive," he continued. "This is intended to attract new manufacturers. The electric component is generally good, and it’s needed in mobility. But on the road we are already further along with 100 percent electric mobility, thanks to its unbeatable efficiency."

While fully electric vehicles are becoming more popular on the road, they are far from what viewers want to watch in racing.

“Motorsport has different requirements. At the 24 Hours of Le Mans they are very different to those in Formula 1 or the junior categories. Either way, it won’t work with fully electric powertrains.

“The new regulations aren’t entirely convincing to me yet. Energy recovery is great, but doing it only on the rear axle and ignoring the front axle doesn’t make sense to me.”

He also believes the cars are still too heavy, despite the slight drop in weight.

“We’re moving a little in that direction now, but it’s just a drop in the ocean," he said on the subject. “The cars are far too heavy. They really ought to be 200 kilograms lighter.

"It always comes down to this: What are you trying to achieve? How do you achieve it? Where do the funds come from?”

Since retiring from the series, Vettel has become an advocate for sustainable fuels through his initiative Race Without a Trace. The German demonstrated sustainable fuels at the Goodwood Festival of Speed, where the racing driver drove Nigel Mansell's championship-winning 1992 Williams FW14B and Ayrton Senna's 1993 McLaren MP4/8 on such fuels. 

“I think climate-neutral fuels are good because there is a need for them in the world outside motorsport - for the many vehicles already on the road, for shipping and aircraft. What you need to be careful about is the origin of these fuels. If you unleash the typical Formula 1 development race on them, things can quickly go in the wrong direction, as was the case in 2014.”

The fuels used during his demonstration needed no modifications to the cars, lowering the barrier to entry.

“With fuels, we should close the door as much as possible by limiting the origin of the molecules and establishing a certain relevance for series production.”
