Takes some getting use to but it feels more like a manual in the lower gears but you have no clutch to disengage. I think the more aggressive down shifts and full engagement feel of the newer transmissions enhances driving dynamics as opposed to detracting from them. Just my opinion. For a heavy SAV the X6 is a lot of fun to drive.

I was under the same impression (that it was the 8 speed auto), but it turns out the X6M does this as well (if not worse - at least from what others have said on this board). I also notice it a lot more when the car is cold, leading me to believe that they are charging the alternator more so than saving the brakes.
