Concept power units from 2030

1.6-liter V4, combined with axial flux motor(s) and a solid-state battery.

Nostalgia and innovation combined with this technology. I’m afraid all I can do is dream and hope.

More likely for F1, than V10.
Why V4 though? I4 worked fine for BMW.

Why would you restrict electric motors to axial flux only?

I wouldn’t limit it to axial flux motors only, but I would like it if they developed them for F1 applications.

Maybe some use them now for one of the motors.

Restrict motors to axial flux only? - Did he say that?

He specifically said axual flux motors and solid state batteries.

Yes - but he didn't say "restrict"

Why V4 over I4? - Packaging.

Okay so what's the advantage? I4 is long and slim, V4 is small and short.

Short is better if you want to add stuff at the end of the crankshaft - like a MGUK.

Not packaging but V engines have stiffer block and shorter stiffer crank, so engine can be lighter and/or rev higher etc.

He said axial-flux specifically an nothing else. No reason to argue about this.

Yes, but slimmer is better for aero, or alternatively you can package more stuff to the sides. And with for example aforementioned axial flux design an electric motor can be very short.

It seems like to me it's a choice based on how good you can design other aspects of the engine and how do you want to package it inside the car.

Not really. Your airbox and exhaust manifold will be located higher on an Inline engine and will ultimately fill space higher up than a V.

What other types of electric motors could they use? Apart from axial flux?

And who sees the V4 actually making its debut in Formula 1? I’m thinking around 2030 or 2033, perhaps.
