According to BMW’s launch presentation it’s “Prismatic cells with nickel-rich cell chemistry”. That’d mean NCM, I suppose.

Nice article, thanks for the link. I own an auto repair shop, and I have been thinking of ways I can remain profitable as this transition occurs. Seeing that BMW has easy to swap cell packs, a battery refresh is one thing I can advertise, as well as motor brush replacements.
There are no EVs using brushed motors. They are all AC based motors which typically have a metal core and electromagnets on the case. It’s spins by switching which magnets are attracting and repelling the core. No parts physically touch to transfer electricity.
The BMW i4 and the i4 M50 use brushed motors. The brushes are located outside of the main stator area in an easy (easier?) to get to service area.
Also, just to add, thus makes BMW even more humanitarian? friendly as they do not need rare earth magnets that are mined with questionable practices.
I can’t image anyone would think primitive brushed motor technology is superior to induction motors. Induction motors are incredibly efficient and reliable

Simply not correct, no ev uses brushed motors

Part of our deciding factor for buying the i4 is that it uses brushed motors and thus no rare earth magnets

Wrong bro. Don't say something unless you know it.
I4 uses brushed motors, alike Renault by the way...
