Concept power units from 2030

Also, the same mass of battery, 25kg, was used for kers as it is for the current PU.

I couldn't find any refernce to a weight limit for the 2009-2013 KERS battery.

But it is doubtful that a battery of 300kJ storage weighed the same as one with 4MJ.

Yes, I was shocked as well but total KERS mass was approx 30kg(most of which was the battery). And current regulations stipulate minimum 20kg for the energy store, maximum 25kg. It was Mercedes who revealed that the ES for both systems were approximately the same mass, for them. Amazing progress.

Well, the two-stroke engine has come up before. But back then, people were talking about opposing pistons. I don’t see that happening anytime soon because that would mean switching to a completely different type of engine, just because of the two-stroke alone.

If one were hypothetically to place an MGU-K on the front wheels for 2026.

What impact would this have on the dimensions of the nose?

How much additional weight would it add?

350kW MGU for rear wheels is 16kg plus 4kg for gearbox.

I would assume that a front MGU would need to be at least as powerful as the rear one, it would also need some sort of differential and driveshafts.

And using an axial flux motor? I still find it a pity that there is no energy recovery at the front wheels for 2026

Not sure.

What power/weight would be expected, and how big would they be?

Current mguk is 7kg and about the size of a typical starter on a saloon car. I believe it is 160hp. Maybe look into the spec mguk at the front of the current Formula E car. Its addition has transformed the racing in that series and taken the performance up several notches.

This article is mainly about axial flux motors for airplanes. However, they already have a 300 hp motor weighing only 8.3 kg. So I assume this is also possible for cars, especially for sports cars and F1 cars.

Unless the supercharging is done via a turbo, it's a waste of energy. So, unlikely to ever happen.
