Nice try E! You almost got me.
I knew the exact BMW description was in the press release but was too lazy to check it. At the same time I knew what they must be made of.
However, to clarify more fully the front (only) fenders are probably SMC (fiberglass) but the bumpers (structural parts, not covers), if the same as the E46 M3 (likely), are thermoformed and welded CFRTP (continuous fiber reinforced thermoplastic). I saw these bad boys at a composites trade show before the E46 M3 was released. I'd like to know specifically what fiber(s) were used in the bumper. I am fairly sure there was some carbon and some kevlar as well but that was just a quick visual/guess.
