Former Formula 1 champion Sebastian Vettel has publicly criticized the sport’s current focus on hybrid engines, urging a shift back to naturally aspirated V10 power units. Speaking in 2024, Vettel argued that F1 should stop trying to closely mirror road car technology and instead prioritize the racing spectacle by bringing back the iconic V10 engines. His comments highlight a growing debate around the cost and complexity of today’s regulations within the championship.
The cost and complexity of hybrid systems under scrutiny
In an interview with Auto Motor und Sport, Vettel described the existing hybrid engines as prohibitively expensive, with little practical technology transferring from the race car to everyday vehicles.
“The current engine is too expensive. Apart from the ‘Hybrid’ sticker, there hasn’t been any transfer to series production because it was too complex and too expensive,”
he said. He expressed concern that the escalating costs could threaten the sport’s competitive balance and accessibility.
He added that maintaining close competition without losing Formula 1’s essence is essential.
“From a sporting perspective, the competition must be as close as possible without damaging the spirit of Formula 1. And people must still be able to afford the sport,”
Vettel explained. His remarks suggest that, despite its technological advancements, the hybrid era may hinder the fundamental excitement and fairness that fans expect.
Racing atmosphere and fan experience remain critical
Vettel emphasized that the grand prix events are about more than just the racing itself, involving large crowds and a vibrant atmosphere. He highlighted the importance of creating a memorable experience for spectators both on and off the circuit.
“A grand prix is a big event with a large crowd. That allows me to explore many new topics. How do I get spectators to the circuit and back again? What do people consume at the track? Where do things come from? What do they contribute to making it a great event?”
Vettel reflected. His concerns extend beyond the technical regulations to the overall health and sustainability of the race weekend experience.
Appeal of the V10 sound and tradition
Reflecting on his personal experiences, Vettel recalled the distinct sensory impact of the V10 engines, noting that the sound was integral to the Formula 1 spectacle.
“I was still able to experience what a V10 feels and sounds like. And that is part of the show and the Formula 1 experience,”
he said. He believes this element resonates with fans by offering a deeper connection to the sport beyond just who crosses the finish line.
“In the past you didn’t just go to the race track to see who would win; you also wanted to breathe in all the fascination around it,”
Vettel added.
While acknowledging a younger generation that might not value the V10 noise as strongly as older fans, he remains convinced the engine’s return could rekindle enthusiasm.
“I do think there’s a generation growing up for whom the V10 sound is no longer as important as it is for us, but who could still be excited by it. The question is whether the engine formula has to be relevant to road car production. I don’t think so,”
he stated.
Balancing environmental concerns with motorsport tradition
Vettel’s call for larger, naturally aspirated engines contrasts with Formula 1’s planned 2026 regulations, which emphasize increased electrical power as part of a push toward sustainability. Despite this, Vettel insists that any return to bigger engines must be designed with environmental responsibility in mind.
“It will move away from this transfer and more towards entertainment. We should stick to what we know, but it has to be done better in environmental terms,”
he said.
He drew a parallel between motorsport and consumer goods, underscoring the need for ethical and eco-friendly production practices.
“The shoe I buy has to be manufactured in a way that doesn’t harm the environment and that ensures fair working conditions. The same applies to cars and motorsport events,”
Vettel explained. This stresses his view that tradition and sustainability can coexist if managed thoughtfully.
Preserving motorsport’s future in changing times
Vettel concluded by acknowledging the inevitable evolution of motorsport but expressed concern over losing its core identity.
“It would be a shame if the motorsport we know were to cease to exist. It’s perfectly normal for it to change,”
he reflected. His comments pose a challenge to F1 stakeholders to find a path that honors the sport’s heritage, remains financially viable, and meets modern environmental expectations, ensuring its appeal endures for future generations.
