Maybe a cf hood, but its weight savings are truly minimal.
I totally disagree. The M3 already has lightweight carpet. I'd be willing to be the next get has even less dense carpet (meaning lighter in the end). I'd also be willing to bet that the trunk and or hood to be CF. BMW bought a large facility some years ago with capability to product small production levels of CF components. The glass and battery are also "no brainers". Like I already said CC brakes are unlikely. It is all about the most weight they can shave off per dollar. CC brakes rated in lb/dollar is very low whereas carpet, glass, battery and CF panels (as long as done in a reasonable high production volume) are quite high lb/dollar. BMW is getting more and more serious about weight and much of this will be seen in the next M3.
