I saw this interesting article on Opposite lock yesterday and have no idea if it's a repost.

Judging by the close relationship between BMW and Alpina, I wouldn't think BMW would allow them to release their new Biturbo without knowing the new M3/M4 possessed more impressive figures.
I'd love to hear some opinions on this.
