Accelerator pedal delay

[nsindre]

I'm taking it to the shop next week, so they can have a look at it.

Never noticed any delay except as already mentioned when in eco mode you have to press more .i have to say i am not keen on autohold ,i like the natural roll on when you lift off the footbrake .

Update:
Went to dealer and had a mechanic test the car, he didn't notice the delay on his own, but agreed with me that there was a delay when we drove the car together.

The best way to notice the delay is to test the difference in response from the pedal at a fairly low speed: compare how quickly you feel the acceleration when you start with a slightly depressed pedal versus a completely released one.

To see if this was a specific issue with my car, we also tested one of their demo cars. It was immediately apparent that the demo car had an even greater delay than my own. I would expect that this is in fact an issue with many if not all ZS EVs.

They said they'd contact MG about it, so we'll see what happens.

Interesting. I’ve driven 4 different ZS EV’s and not really noticed anything. I suppose that it might come down to driving style or maybe I’ve just been lucky. They’ve all driven very much the same. I use auto-hold all the time and usually regen 3 or 2 in normal mode Mostly. Starting off requires a degree of anticipation but that’s best driving practice anyway.

Dealer will be taking another look at the car on Friday. I doubt they'll discover anything different this time around, but at least they seem to be taking the issue seriously.

Hi.
I.ve searched the from for an answer but I cannot find it's been covered.
The zs ev has a delay in applying any power when you press the accelerator.
I know this is common on the zs ev as all the reviews I have watched online also mention the same issue.
It is unusual for an ev as my last 2 leafs would accelerate as soon as you touched the accelerator. They had less power but felt as fast or even faster due to the quick sprint off the line movement.
This leads to me pressing the accelerator a bit harder than I need and I end up spinning the wheels too often.
One of the things I like about the ev's was the ability to move off quickly as soon as you need it too but this delay is very annoying and the 1 thing on the car I would really like to change.
I.m not after a sports car but just good acceleration in the city.
Btw even in sport mode there is a small delay.
Has any one noticed that a software update has improved the pedals reaction time?
Cheers

Have never noticed any delay on go fast pedal??‍??‍

I've never noticed any delay on the pedal on my ZS EV other than when it is in Eco mode.

There is definitely a delay. The response should be instantaneous, as soon as you touch the accelerator. It isn't due to autohold as you can experience it when moving if you put your foot down hard on the accelerator. It appears to be less in sport mode. It must be software related and should be fixable, come on MG!

in ECO mode? try Sport mode or Normal

that's the point of ECO mode, to delay fast response when moving the car from standstill thus saving electricity consumption. If you hit the pedal hard and fast, there is no delay, reacts instantly as the ECO settings is overridden for safety (overtaking, etc...)

I have the Mk1 Exclusive and the Mk2 Trophy and have not noticed any delay with either unless I have the hill assist on

Delay doesn't affect economy. If it did you could make it really economical by having a 10 sec delay. Try this, when stationary dab the accelerator pedal. Nothing happens in any of the modes. If torque was instantaneous you should feel a little jerk forwards. Other evs have instantaneous torque. This is possible as the signal from accelerator to electric motor travels at the speed of light. The only thing in the way is the car's software. MG's issue appears to be either bad programming, or (heaven forbid!) on purpose to make it feel more like a smelly, noisy, old fashioned petrol car!

I think what is meant here is, throttle response is not as swift in eco.

Acceleration takes power, if the car limits the amount of power that can flow to the electric motor, it will feel like it is slower in response.

Delay I'm talking about is the delay in the accelerator pedal travel - in ECO mode the pedal travel is slightly longer than in NORMAL or SPORT so it uses slightly less power, slower the car moves from standstill, less power is used and less stress on the battery.
With my auto-hold switched off, the car crawls forward by itself as soon as you release the brake pedal. When you have auto-hold turned on or when you start from P, there is a slight delay between pressing the accelerator and the car moving, due to the electronic brake release time.

I tried dabbing accelerator in all 3 modes and it reacts in all 3, it does jerk forward. There is a slight (I'll guess, a bit less than 50mm) "free travel" of the accelerator pedal before it makes "contact". Every time I hit the accelerator pass that point, the car instantaneously reacts, no delay.
