Cruise control

I think it's the adaptive regen that's making the difference.

Not sure... the distance to the preceding car is now constant as it reacts quicker when your car needs to accelerate... what surprised me is that it is not catching up faster because it accelerates more (or briskly) but because it accelerates earlier (and softly); otherwise it would be even more shaken driving, which is what I was expecting when I turned on the AAC

That would make sense - it is clunky because it is fighting high regen, which is what I have always used it with.

In my experience at the weekend with ACC and adaptive, it’s still not a smooth deceleration, more a jab to the brake.
 
I've used ACC with adaptive regen several times, but always with Normal or Eco modes, and it can still yo-yo. Next time I'm going to try Sport (or Custom with Sport drive, together with adaptive regen) and see if the above theory holds. :)

In my post above, I was using Eco and adaptive on the m’way. Custom may be a way forward as I have another trip to make next week which will be partially m’way.

It's not a theory... it's a finding! 😀
Reminder: I am talking about 1 lane for each direction regular roads with traffic.
 
After a short test on dual carriageway and motorway (with a 60 mph limit most of the way :( ) it does seem to be better than with high regen. Still not as good as I would like but sorta usable.

Did you try it in Sport Mode with Adaptive Regen?

I'm probably going to try Custom with Sport mode settings and Low Regen.
 
Sport, and custom with sport accelerator didn't seem any different to me. Annoying the car doesn't remember the setting though, sigh!
 
My car remembers my Custom settings ... it just doesn't remember to select the last mode chosen - it always reverts to Normal and regen 3 at every restart (which is by design).

I don't really like the adaptive part of the MG4's cruise control. I find it slows too dramatically when it comes up behind people and is slow to resume. Like bowfer, I much prefer non-adaptive cruise control that I can flick on and off exactly when I want to.

ACC is a joke. I'll decide how my car performs, not the person in the car in front of me, thanks. If the person driving in front is hopeless, then so is my ACC. No thanks.

When replying to this post from 10 months ago, are you talking about adaptive cruise control generally or specifically on your XPOWER?

My XPower. After doing as much research as I can, it seems I can't switch it to standard cruise, so I don't use it. Very disappointing.

Just so I’m understanding you properly, ‘standard cruise’ is where you set the speed and the car continues at that speed irrespective of any vehicles in front?
Whereas adaptive cruise control regulates the speed to maintain a safe distance (which you can adjust) from the vehicle in front.
I can’t imagine any world in which ‘standard cruise’ which would, by the above definition, allow you to get dangerously close to, or, autonomous emergency braking not withstanding, crash in to the back of the vehicle in front, is not a terrible option compared to ACC.

So, to be clear, you are happy to let the ACC with all it’s driveability faults (see comments above) take control of the vehicle while you do something else? I like to think that I am in control of the vehicle at all times and I have never allowed cars with conventional cruise control to drive too close to the vehicle in front or crash into it and I suspect that I am not alone in this!

Yes, I must've missed all the news reports warning us of the numerous crashes caused by using 'old-fashioned' CC, which has been equipped in vehicles for around 40 years now. By the way, can someone update me as to how Tesla etc are going with their driverless-cars-utopia testing recently??.. Oh, hang on, I remember now - constant life-threatening glitches thanks to another ridiculous shiny new technology. Don't worry about the details, just look at the headline!! Snake oil is still for sale, just 21st century-styled.

If you plan your overtakes relative to the safety distance setting you've selected then ACC can work just like normal cruise without causing any slowdown. (ACC in the MG4 is even better once you've had the latest updates as it no longer slows down in sweeping bends - i.e. that "crappy Chinese software" that Bjorn Nyland often refers to has been fixed).
