I just had an older (pre-AP) 85 as a loaner (my normal car is a P85D). I was surprised at how slow the acceleration was especially in the <~35mph range. Is that because of traction limitations with 2wd? It felt about the same as my P85D with Valet mode enabled. As I got past 35mph it felt much more powerful. I tried turning off traction control but no change.
I've also had a loaner 85D and that one felt surprisingly quick compared to my P85D.
