I've complained ad nauseam about this and how the X3 4-banger loaners I've gotten feel so much more responsive, when daily driven, down low (what most people do everyday). The mppsk tune on the M40i uses "overboost" on kick-down to thrust you forward & give the almost immediate sensation of brutal torque/speed but it's not practical in everyday driving. Otherwise, it feels lazy on any gear below 3K when cruising.
