Gear shifting in EV mode, Warning

It is on the same screen as the software, you just need to swipe up on the touch screen there is more below the information you posted. I wonder if the RHD software is different to the LHD for the ECU. Maybe as it's Chinese the RHD software was written later or by a different team.

Rather stupid of me! It happened before... Must watch te green indication line more often!
Second try... I think there is no difference?

That is interesting to read Weiro...
I do also have this interruption at around 120, but not as forceful I think.
I will observe it again.
So, in fact we have two cases at 80 and and 3 or 4 at 120 as well.
Please keep an eye on the 80 shift as well, thanks!
My MG dealer contact informed me that he got word of an upcoming software update concerning the EDU or Electrical Drive transmission Unit. That would be good news.
I did not have a grave power drop at 125km but stil not smooth.
I did confirm, while watching the motor rpm on the Hybrid info page of the info cluster, that all 4 gears do operate. First shift from 1 to 2 at +/-40km (in auto hybride mode only) , 1 to 3 at +/-80km and 3 to 4 at +/-120km. In the EV mode the first shift at 80 with rpm dropping from 9000 to aprox 6000. A large dorp indead. I wait for further news and let us keep each other informed.

@Henri8 Sorry I misunderstood the problem you were having. I've been out today to try to replicate the problem you have between 75-80kph but have been unable to do so. When you experience the problem what happens to the motor rpm does it drop more than it does when it makes the first gear change? I was wondering if perhaps it's possibly a gear box problem and maybe it's going straight from second gear to forth missing out third.
I have bought my MG EHS Phev in March, and I have exactly the same problems, when I drive in EV-mode abt. 79 - 83 km/hrs. it feels like the engine stops or drops, just for a second and then it drives well again. I have just written to the MG dealer in Denmark asking him if he knows about this problem from others.

Thanks for signing in on this issue and ask your dealer to confirm that a software update is planned at what date by MG!

I just talk to my MG dealer, and he told me that all MG EHS PHEV have the same "problem" with a short stop around the 80 KM. He told me that it was normal. He had ask the MG headquarters i Denmark and told them at it was OK and they have not been advised about an update on this issue. If any of you guys received another answer/information I would like to see or hear it.
I saw now that you created a second thread about gear shifting in EV mode so I quoted it back to the original one.

They can say it is normal, but it is not normal at all when you try to overtake traffic on a dual road!
It is dangerous if you are not aware of this issue beforehand.
I also have no confirmation yet on a future update. Only hearsay....
 
I asked miles here in the UK about this and this is his reply

The slight "stall" is the unusual effect of having an electric motor working on a 2 speed gearbox. It uses the gears on the EV side to effectively give you 10 gears overall (with the Petrol engine and motor working together). When in hybrid mode, the engine power is able to mask the motor's gear change, but in EV mode, there is nowhere to hide!
In Hybrid mode, the car uses the logic that the EV is most suited to lower speeds (sub 25mph urban traffic), and the engine is more suited to faster road speeds. So on a mixed commute, it will try to use the engine above 25mph to eke out the EV range further (for example, if you do a commute which involves leaving an urban area, driving between towns, and then driving back into an urban area).

The ZS EV only has one gear, so doesn't have this effect. It's only the PHEV which has the two-speed gearbox on the EV motor.

Thank you for your reply. This issue also affect the 0-60 (0-100km/h) speed run it’s nothing near the 7 seconds they claim

In my experience the ‘slight stall’ is a ‘huge stall’ when you accelerate with more than 80% power in the EV mode.
In the hybrid mode motor gear shifting happens earlier, around 40kph, and the second at 80, third at 120. ( 4 gears )
In EV mode only the big shift at 80 from around 9000rpm to around 6000 and a second one at 120. (3 gears)
I would strongly advice a software update to have 4 motor gears in both modes. But... who am I? Henri the 8th;-)
 
Hallo Gelf,
Join the party! It is not a matter if this problem exists anymore, but how MG is going to fix it!
Please do so as I did at the Amsterdam branche.
Groet, Henri
 
To my knowledge no fix has been released. I did send a preliminary outcome of the voting poll (so far 34 members did vote) to Continental MG dealer van Mossel. No reaction yet.
I repeat, this issue in my view is not only unfortunate but unsafe and dangerous in case you overtake traffic on dual carriage roads. So, keep this in mind and switch over to hybrid mode beforehand!
 
I was in hybrid mod, I coming up a slip road to aroundabout, the traffic started moving so continue on to the roundabout I was still slowing a bit then the traffic speeded up so I started to then it happened. At the time did not know if I was using the electricity motor or both. But now I have a understanding of this will keep a eye out for this.
