V8

A V8, with or without a turbo, and hybrid in the region of 20-30% seems like a reasonable-guess possible compromise as things stand.

Alonso won one of his two titles driving a V10 and one driving a V8, and when he demonstrated his 2005 Renault at the 2020 Abu Dhabi Grand Prix he clearly had a lot of fun chucking the car around.

"I love the the sound of the V8, V10, and, you know, we all experience that, and it's probably one of the best memories I have from Formula 1 and one of the best cars that I drove," Alonso said.

Perhaps manufacturers would agree to a different, bigger engine - a V8, for example - with a turbo and some hybrid element, but not as much as the 50% of total power planned for next year.
