Again, there seems to be mixed info from BMW;
BMW has also released the curb weight of the Z4 M40i (3,443 lbs)
https://www.bmwblog.com/2019/01/14/b...r-the-z4-m40i/
Jalopnik and several other sources site "official" weight of the 30i at 3287 lbs;
https://jalopnik.com/the-2019-bmw-z4...har-1829163317
Based on these "official" figures, it gives us 156 lbs or 71 kg's.
Again; guess we'll have to wait until some of us weigh the cars to know for sure
Cheers,
