Okay ... you are right!
But these numbers are the target weight for the new F80 M3, but it seems like they have make great advantages in weight reduction issues and could really reach this target!
These numbers couldnīt be reached by putting CF body panals over an regualar steel car body ... but if you look at the i3, you see that BMW and SGL could make an complete body from carbon composite and this at an tolerable price tag ... so it seems really possible, that BMW combined those possibilities with high straight steel parts to make an really light car body ... this is also the reason for the new intern lable F80 instead of F30!
The bad thing is that BMW has decided, that because of the great weight reduction effort the new M3/M4 doesnīt need an special and innovative new engine
to reach the targeted performence numbers well above all other cars in its class.
