F1 bosses agree to engine design change for 2027

At the moment, the cars require energy management techniques such as recovering energy while on full throttle, which leads to a speed drop-off before corners and through some fast curves.

A statement from the FIA said the meeting had agreed unanimously on the changes.

The details will be discussed in technical groups involving teams and power-unit manufacturers before a final package is agreed.

The changes will require development to existing engines but a senior insider said: "Everybody is in the mood for a challenge."

The meeting also echoed the F1 drivers' views that changes to the operation of the engines for last weekend's race in Miami had been "a step in the right direction".

The drivers almost unanimously expressed the same view over the weekend in Miami.

McLaren's world champion Lando Norris said after finishing second in the race on Sunday: "It's a small step in the right direction, but it's not to the level that Formula 1 should still be at yet.

"If you go flat out everywhere and you try pushing like you were in previous years, you still just get penalised for it. You still can't be flat out everywhere. It's not about being on as early on throttle everywhere.

"You should never get penalised for that kind of thing and you still do."
