Hamilton: I don't understand why F1 cars are getting heavier

World champion Lewis Hamilton does not understand why Formula 1 is letting cars get heavier and heavier while also trying to improve sustainability.

Hamilton: I don't understand why F1 cars are getting heavier

F1’s new generation of cars in 2022 are set to be the heaviest ever, with the minimum car weight currently set at a whopping 790kg.

The move to heavier turbo hybrid power units from 2014, allied to improved safety structures and the arrival of the Halo, have contributed to a big hike over the years.

From around 640kg at the end of the V8 era, the cars went past 700kg in 2016 and are now nudging 750kg.

The extra bulk that is carried around has contributed to cars being less nimble, and is believed to be a contributing factor in why venues like Monaco no longer appear particular well suited to F1 machinery.

For Hamilton, the extra weight also seems to go against a push by the wider world for cars to get lighter in a bid to use less energy.

“I don’t understand why we’re going heavier,” he said. “I don’t understand particularly why we go heavier when there’s all this talk about being more sustainable – just as the sport is going in that direction.

“By going heavier and heavier and heavier, you’re using more and more energy. So that feels that’s not necessarily in the right direction or in the thought process.”

As well as cars being heavier, they are also much bigger in dimension compared to previous years.

Hamilton says the whole feel of the cars has changed hugely since he started in F1.

“The lighter cars were more nimble, were nowhere near as big, naturally, and so racing, manoeuvring the car, was better,” he said.

“On the tracks we’re going to, they’re getting wider. In Baku it’s quite wide in places and of course it’s narrow in other places.

“Monaco was always relatively impossible to pass, but now the cars are so big that it’s too big for the track. And, as I said, as we get heavier and heavier, that’s more energy we’ve got to dissipate – bigger brakes, more brake dust, more fuel to get you to the locations. So, I don’t fully understand it.”

Former world champion Kimi Raikkonen says the change in car weight since he has raced in F1 has never been a shock as it has happened gradually.

However, he says that it is only when looking back in the history books that the scale of the change hits home.

“It’s a lot when you see the old cars next to this year’s cars or even the last year’s cars,” he explained.

“Some years it’s ‘how small they look!’ So, obviously we are not here to design.

“I think if we still did race the mid-2000s or whatever year you want to pick cars, it wouldn’t make any difference to racing. It just wastes an awful lot of money on the way to get to here and nothing else has changed.”

It has owned up to the mistakes it made which led to its troubled W13. And while its task to return to title-challenging contention is not small, its 2022 season seems more like a blip than the beginning of a downward spiral.

The death of Dietrich Mateschitz last month has not only deprived Red Bull of its visionary founder, it has shorn Formula 1 of one of its most influential benefactors. Mateschitz himself was famously media-shy, preferring to let the brand do the talking on his behalf. And, while it’s now normal to speak of Red Bull F1 titles and champions made, Mateschitz never assumed it would be easy or even possible – as ANTHONY ROWLINSON discovered during this previously unpublished interview from 2006…
