To a point, yes. N52 630i is a little less torquey than our N53 530i that we have but not a major issue in the real world. N52 on 6 sounds fruitier than slightly sterile sounding N53. I'm using ours daily at the moment and its a pleasant place to be. Not a hugely different driving experience than an e60 but friends, etc. notice the 6 when they've never noticed the 5's I've had.
