The trans looks like it shifts super fast and crisp!
I am not sure to be honest. I have a 535d with sport auto too, and I was very surprised when I picked up the M550d and did my first shifts. It shifts incredible fast and you even feel the shifts (even more than in the M3 DKG). It reminded me a LITTLE bit of the SMG
. BMW has incredible sporty Auto Transmissions. It also holds the gears if you want it to.
