OP's post#1 says 4800lb, which is the curb weight, and that is published data from BMW that does not need BOM nor teardown details.
Focusing the discussion towards weights of floorpan, cowl, front rails, etc. per your definition of platform appears to be missing the point, namely, that hefty 4800lb likely does not help fuel efficiency.
E.g. BMW publishes 300 miles of range for 81.5kWh(usable), or 3.65 miles/kWh.
The i3@3000lb with 30kWh(usable) goes 150 miles, or 5 miles/kWh.
Tesla Model 3 is around 4 miles/KWh, or 26kWh/100 miles per EPA.
So yes, BMW has a
dedicated EV platform (i3 with CFRP) that are
20-25% more efficient than Model 3, while BMW's hybrid platform(e.g. i4 ) is not based on published numbers.
