Formula One champion Jenson Button backed the FIA and F1’s recent decision to make tweaks to the new regulations ahead of this weekend’s Miami Grand Prix.

F1 introduced new hybrid power units for 2026, with 50% of the power coming from electric power as part of its push towards sustainability. However, the new cars have come under intense criticism from drivers who have bemoaned that they are too complex and not fun to drive.

“It always takes a little bit of time to fine-tune new regulations. I think the changes we have here will lead to a more consistent car for the drivers. They’ll have a better understanding of what it’s doing. I think they’ll be much happier,” said Button, the 2009 world champion.

“We want drivers to be out there having fun and enjoying themselves when they’re racing. So it plays a big part in it because when they get out of the car, and they’re unhappy, it doesn’t look great. So yes, I think fine-tuning was necessary,” he added.

Following the cancellations of the Bahrain and Saudi Arabian GPs, the teams have had a five-week break since the previous round in Japan. Button feels this gap in the calendar would have given teams valuable time to assess things and expects the field to bunch up in Miami.

“I think we will see the field a bit closer this weekend, especially the top teams. Mercedes still has a bit of an advantage. But if they slip up, McLaren and Ferrari will be there waiting. The Ferraris are very good off the line. So if they get into the lead, it’s going to be difficult to overtake them,” the former McLaren driver remarked.

Commenting on the drivers’ championship battle between Mercedes teammates Andrea Kimi Antonelli and George Russell, Button reckoned that whoever gets on top this weekend could have an advantage.

“I think it’s interesting here in Miami because Kimi was really fast last year. So it’s going to be a tough fight for both of them this weekend. We’re back from a big break, and whoever gets down to the top step of the podium has bragging rights,” said Button.
