Topspeed:

I find it hard to believe that they added nearly 400 pounds (like for like).  I guess the AWD models will be even much heavier?  Are we sure the weighing standards haven't changed (they did for Porsche)??

Ya, I remember when the 718 GT4 came out Andreas Preuninger  said something about new weight standards.

I believe it was something like "before it was the lighter car possible, now it's the standard car that counts"

Btw, the 2014 M4 coupé(auto) weights 1612Kg, the 2018 M4 coupé(auto) weights 1670Kg. Does it have OPF?
