Mercedes boss Toto Wolff has sparked debate after suggesting F1 2026 cars could reach top speeds of 400 km/h. The bold claim comes as Formula 1 prepares for a major regulatory overhaul in 2026. The new rules will focus on a 50/50 energy split between V6 turbo engines and a much-expanded MGU-K electric component.
Active Aero and Radical Changes in 2026
To make the new power units work across varied circuits, F1 2026 cars will shed drag and downforce. They will also feature active aerodynamics on front and rear wings, boosting straight-line speed. Speaking to Auto Motor und Sport, Wolff revealed: “When the full power is deployed, we will scratch the 400 km/h limit.”
This could potentially surpass Valtteri Bottas’ 2016 record of 378 km/h at the European Grand Prix. Circuits like Monza and Mexico may witness fearsome speeds rivalling even the Indianapolis 500.
Drivers React to Wolff’s Claim
Not all drivers share Wolff’s optimism. Alpine’s Pierre Gasly dismissed the hype: “I don’t believe stories. I only believe what I see.” He added, “I’m sure we can even go 400 with those cars if you change the gearbox and increase the straights.”
World Champion Max Verstappen also joked: “Maybe Toto’s engine can do that. I think the FIA has already explained that they won’t allow that.”
Esteban Ocon admitted the figures sound extreme: “This 380-400 km/h looks quite scary when people comment these things.”
Ferrari’s Charles Leclerc, who tested an early simulator version, acknowledged the rapid development: “Every time you’re on the simulator, it changes by a lot.”
FIA’s Stance on 2026 Speed Projections
The FIA has not seen 400 km/h in its own simulations but remains open to team data. FIA Single-Seater Director Nikolas Tombazis explained: “There will be quite a lot of new provisions in order to manage the energy better. In our simulations, we are between one and two and a half seconds slower next year at the start.”
What to Expect from 2026 Cars
The governing body expects higher top speeds but reduced cornering performance, meaning lap times may remain close to current levels. With continued refinements, the 2026 cars may still evolve significantly before hitting the track.
Whether Wolff’s prediction of scratching 400 km/h comes true or not, F1 fans can expect a thrilling new era in 2026.
