Throttle lag from stop
I've had my 2018 M40I for over a year and a half. The car is going in for new rear axles soon (steering vibration). The axles are on order and hopefully it solves the problem. I've noticed this car has an annoying throttle lag starting from a stop; more than my 2012 X3 3.5. Once the car starts moving, it really hauls, but right after a light turns green, under normal acceleration it takes a second to get moving. This is in the comfort setting. Is this inherent in this car due to the turbos or can this situation be improved with a software update. Thanks

Probably programmed that way on purpose to not snap all the necks of the passengers in the car. Mines the same way. Even the X3M seems to suffer from the same problem.

I'm told a tune will get rid of it, but the engine is already tuned to provide the maximum amount of torque that the zf 8hp50 transmission is rated for. Adding a tune exceeds the manufacturer torque rating, and I'm nervous about longevity, as I plan to have this vehicle for over a decade.

Sport mode's throttle is /much/ snappier, more responsive, more eager. Speaking from experience, be careful if you switch into Sport between red lights particularly if you've been trundling around town in Comfort for a while... the throttle response sharpens up so much I nearly rear-ended the car ahead of me when the light turned green.

This is also my biggest frustration with the vehicle. I also have a 2019 X5 40i which doesnt suffer this at all. So its super frustrating to get into this vehicle and have such a lag. For me, in sport it isn't any better, just way more push when it does finally go. Sport Plus is horrible for me all around. The throttle feels way more soft, feels a lot slower, but keeps the gears open longer. So its makes a lot of noise but doesn't go anywhere. lol
Its even worse if you come to a rolling stop say to do a u-turn. When you want to move, its like it has to think for a while and then it goes. Its a small nag for a great vehicle, but it is super frustrating for something billed as a go-fast SAV. Stinks that my X5 feels much quicker because it actually does what you tell it to do with the throttle.

Vibration starts a 52mph and ends at 56mph when accelerating. Thanks all for the feedback. I'll try sport next time out and see if there is an improvement.

It's not just BMW that suffers from this. We have an Audi S5 Sportback, which is kind of the M Performance level for Audi and I believe has a version of the exact same transmission and we occasionally experience the same thing. I try to make sure at a rolling stop to manually drop a gear before taking off. That's hard to remember all the time, but it can help, as many times in this case the reason for the lag is that the gearbox hasn't dropped all the way down since the car didn't come to a complete stop. Sport mode helps tremendously in this situation, as the coding is set to downshift earlier and more aggressively.

My 2015 Z4 s28i has the same issue. Going to sport helps, but still too much lag for me.
Our 2011 Acura MDX has the same issue. Press the gas and hope for power. It has a terrible lag and it is not turbo. My 2016 Acura TLX also has lag (non turbo). Once the tranny finds its spot and the engine gets going, there is plenty of power. But in that 1-2 seconds, you may be out of luck. That leads me to think the tranny programming is at fault. |

I will need to return to the dealer to get my vibration checked out. Last time I went in, they said a road force balance for my new wheels/tires, which is obviously not the issue when you get vibration from throttle application only. |

I have tried that so many times now I think I look like a fool (more than normal). It acts the same, just a long pause and then takes off. Oh well, I do appreciate the feedback and suggestions! I have even tried in manual mode with no luck.

I haven't driven my M40i enough to notice yet. Could be the engine and/or transmission tune. Sadly, I'm coming from a manual...which means now I will notice tip in delays However, on my test drives, I didn't think the M40i was nearly as bad as the S5 Sportback which others are complaining about. That car was not worth it over the standard A5/A4 just based on it's around town cal in my opinion. |
