Actual power to the wheels ?

Not sure if this has been covered but, do we have driveline loss like an ICE drivetrain loss and transmission getting BHP to the wheels?

Each drive unit has a reduction gear set. I am sure there is a very small amount of loss to the wheels. It would be nowhere near the loss of an ICE car due to no transmission.

Are dynos able to properly calculate the amount of power they are producing? But knowing BMW I am sure that they are producing more than officially claimed.

I mean it’s such a wide power delivery with electric. I’m just wondering if with less loss and constant powerband if our wheel HP if equal to a 630 or 640 hp ICE engine
