Did anyone ever figure what the deal was with perceived hesitation when hitting the gas?

Actually, doesn't it have something to do with the drive-by-wire throttle?

Car: I started a few threads on this after driving the e90 and reading a few posts about hesitation in accelration. See e90post.com, e90style.com. I don't know what the deal is. I drove the car with DSC turned off and it still had that little hesitation. Smooth otherwise, powerful, but not quite as responsive as say the e46 zhp. Don't have any answers yet but keep asking and maybe we'll all figure this out. If BMW folks are reading, you might want to clue us in. This is getting to be a huge issue with a lot of people!
Cheers.

The first thing you need to find out is if the DBW is trainable in the sense that it learns the way you drive just like the automatic transmissions do.
If that is the case then the car will learn the way you drive and become more responsive ...
I remember when everyone complained about this on the E46 when they first came out with DBW (Drive by wire) and BMW gave it a quicker repsonse time in I think it was 2001 1/2 models (or it might have been 2002 models). I doubt they went a step backwards on the E90, that wouldn't make sense.
Anyway, keep in mind you are test driving cars that are not only driven by other people (so it has many habits to learn) but the cars are also brand new and not broken in. I have found it takes 3000 to 4000 miles to break in and then these cars get much more responsive.
