i don't perceive the hesitation, and in fact, like most automatics, the car wants to creep forward when stopped, and requires a foot on the brake to keep it stopped. except for rentals, i've only driven manuals since 1970, so perhaps i'm not the most sensitive to automatic transmission nuances. mine is a 2012 x3 35i, picked up late jan pcd. if you want gentle acceleration, it will deliver that. if you want vigorous acceleration, it will deliver that. i find it quite simple to get the response i want with the proper pressure on the accelerator.
