the volt, bolt, i3, leaf, etc are built identical to ICE cars that costs $22-25K. They have cheap interior, cheap parts, cheap everything. The I3 is considered the lowest of the BMW lines. Cheapest car that they put together. 
The volt/bolt are likewise the same garbage. 

OTOH, the M3 is supposed to be better than a BMW 3 series. As it is, the M3 appears to be just that. 0-60 in 5.2 seconds and that is on the base model. The Dual that will be coming will be 0-60 in less than 4 seconds. 
As such, the M3 is basically, worth more than ICE cars that it competes against. 
This is the same as the MS/MX. 
Tesla started at the high-end for this very reason. They could not design and build a vehicle on the low-end that would compete against comparable models. And other car makers absolutely do NOT want EVs gutting their ICE models.
