NosherN – Thank you so much for that detailed explanation. Even though I have next to zero technical or mechanical knowledge that sort of made sense to me! I do tend to switch into EcoPro mode straight away (or as soon as I remember to) and have never experienced any lag (unlike the Tiguan which was laggy as hell in Eco), so I will try it today in Standard (Comfort) mode and see if that makes any difference. I have a 110 mile round trip today, although around 90 miles of this is motorway. I have never found the need to use Sport mode in BMW’s as I always find standard and even Eco Pro modes to be extremely responsive, even for rapid overtaking. Sadly my wife is no longer able to drive, so it won’t be due to different drivers.
Reference the different auto gearboxes, until last year I had a privately owned 2015 BMW 520d Auto. Do you know which type of auto that would have had, as there was no lumpiness in that car at all? I always drove it in EcoPro mode and there was never an ounce of lag either. In fact it didn’t feel much slower than the 530d company car that I’d had before it.
I don’t want to overplay this ‘lumpiness’. It really is minor and even when it’s done it my wife says that she cannot feel it at all. It’s also only apparent at very low speed and revs in certain conditions, not during normal driving. I suppose that having driven hundreds of different cars and probably around 30 BMW’s I pick up on even the slightest nuances between cars!
