Lewis Hamilton has declared Formula 1’s new rules for 2026 the “biggest shift” during his 20 years on the grid.
F1 is gearing up for a major overhaul this season with new power units and chassis regulations coming into effect.
On the engine side, power will be more equally split between the 1.6-litre V6 ICE and a much larger MGU-K hybrid system.
Meanwhile, the 2026 cars are 30kg lighter, have around 30 per cent less downforce and feature active aerodynamics on the front and rear wings.
That means Hamilton is expecting a radically different competitive order and a new approach to how drivers go racing.
“It’s the biggest regulation shift I think our sport has seen, at least in my time,” he said via Formula1.com.

“Every single time that it has been a shift into a new regulation, it’s been a massive challenge.
“Everyone starts from scratch, so it really levels the playing field.
“Then it’s really all about development, who can develop faster, who comes up with the best ideas, and then a unified team growing at the same pace.”
A key factor in 2026 is expected to be energy management, as drivers compromise between maximising straight-line speed and saving enough battery for an entire lap.
“I mean, as drivers, we adapt, that’s what we do,” Hamilton continued.
“It’s going to be a massive challenge this year, for sure, for every driver, to adapt to the power unit.

“Whilst it’s still the V6, recharging this battery, the de-rates that you have, and really trying to understand how to utilise the power per straight, and recover the most and be the most efficient…
“This is the period of time where you have to learn to be the most efficient driver that you’ve ever been, and that’s utilising all the tools you have in your armoury as a driver to save fuel, to recharge, utilise the power, use the grip, and put all these things together.
“I think it’s going to take a lot of work from the engineers to communicate and help the drivers to be able to extract everything and its full potential.”
Haas driver Esteban Ocon echoed Hamilton, claiming drivers will need a whole new mindset for 2026.
“It’s a very particular way of driving the car,” he explained. “There’s going to be a lot more management on the engine side and on the hybrid side.
“The car itself felt pretty good. The balance was decent, although of course it was our first taste in the simulator, so we need to see how it is in reality, but the level of grip was good.
“Clearly, the biggest change is from the engine side, and that’s going to be the key for us to be prepared. It’s an exciting challenge, and it’s a different way of driving compared to before.
“I think we can forget everything that we’ve learned since go-karts on how to go fast, but it will be interesting to learn a new driving style and hopefully find speed with it.”
