"mileage" disappointment or there's wrong/normal here?

This is just city driving with a bit of heating (it was 10°C this morning). Trophy ER.
Depending on driving style it can go way up. This was normal driving.
Average total is 15.5. highways, ect.

Your ODO is even lower than mine.

Welcome to these space ships ?

That's how i feel this car is... It's cool.

I'm waiting to discharge 80% to 20% to reply this post. Doing some testing - but so far its around 3-4km per 1% with a/c on and normal driving mode.

Its not sluggish in eco mode and it does speed up well on highways so I don't need sport.

It can charge at home as many times as it needs but i wont sacrifice the fun of the torque this spaceship has.

I'm wondering - and must be true - that over time we are going to get less and less range with the same driving style and battery max threshold ?

While I drive I tend to balance "gas" pedal, so I coast as much as I can and regen whenever is needed or when makes sense. I do not worry about degradation, MG4 have hidden buffer, same as all MG electric vehicles, so even in 100k it will show 95% SOH ?
I do not let it discharge much, I top up 20%, because in research I made over the net I found out that is the best way to preserve battery health and get 2-3x more cycles with same degradation level. I do not obey much what manual is saying because it is written for general use, not specific.
I'm still a new owner but I plan to charge it from 50-70% or 40-60% because I don't have long rides during the day. If needed to go somewhere urgent and far, I have 120kW charger 2.5km from my place, and 77 ER is good for range anxiety problems LOL

Not to be paranoid... But im testing normal mode to see its efficiency... And last 80% to 24% it got almost 7 hours on and 191 km...

60% runs 191 km... That means 30% goes for 85km, so 90% up to 255km

That is nowhere near 450km i was promised...

Now its not that i want to run 400km before charging, but i was expecting at least 300km.

But this "mileage" seems like whack.

Is this happening to everyone? Im just paranoid about this performance.

Im going Sport mode this next charte to compare - and then ECO... And then normal - and so on.

If it doesnt vary that much - i would just go with sport horsepower just because it gets the most of it when needed (and in my city i do need to boost up to pass other drivers)

I'll post next charges stats...

I don't think mode affects consumption that much. It's more the way you drive. Yes if you push sport mode, it will use more, but if you drive the same as you would in eco, then I don't think you'll see much difference.
Speed is the killer, I think drag increases with the cube of the speed.

Then there's other things like temp that affects battery efficiency, road surface, (I've noticed consumption increase on wet roads, as it takes energy to displace water away from the tyres) , then there's head winds.

So the 400km is based on you driving very slow, so accumulated short slow drives around the suburbs, with efficient use of regen. "If you stop too quickly you can exceed the batteries ability to store the extra energy"
Watch the power meter, if it starts going over -20 your probably going to start using the brakes.
A long fast drive will be much less.

7 hours for 190 km on a hot day with aircon running the whole time is going to use a fair chunk of juice.

forgot to mention A/C

Same as you drive turbine ice, you can get 5L/100km or 15L/100km.
EV's are heavy and fast acceleration from stop or while driving will take more energy then slow start/slow acceleration during drive. Just follow your percentage usage (small number on the down right part of the screen). For example 30 is 54Kw power draw in a moment. Same with regen, 20 is 36Kw of charging back to the battery.
I get more then WLTP with my 77ER Trophy. But I can spend the battery in half the WLTP. It depends how you drive.

PS. Numbers for consumption/regen I shown are related to 77Kwh battery, because I have that one. For 64 or 51 models it will be slight less.

Are you doing loads of small trips? In either cold or warm climate where you need heat/ac on you are using "a lot" of energy bringing the car into a decent temperature, and it restarts doing that for each small trip.

 

[Rolfe]

In my experience it's the heater much more than the A/C that affects range.

 

[mg4nick]

Do you cool the car before you get in (using the app)?

I suspect that the car is misreporting the amount of energy used by the AC. If I do a single long trip (80+ miles) the battery pie chart shows 1-3 kWh used by the AC.
If I do lots of short trips (and spend longer times in the car due to being stuck in traffic) the car reports the whole energy (since last charge) as being used for "driving power"...
I suspect that if the AC energy used on a short trip is below some threshold it may be counted as "driving power".
Given your low average speed you are probably stuck in traffic a lot of the time.

Driving in such conditions I'd argue you should NOT expect anything close to the WLTP figures...

If you had an ICE car before the MG4 maybe you can compare the fuel consumption for you usual trips vs the expected fuel consumption from the specs (you may discover a similar shortfall).

His screens show exactly what kind of driving he has. 6 hours for 191km. Spikes in energy consumption shows he's harsh on the pedal. And for sure a lot of standing in the traffic. With ICE, consumption in those conditions would be 2-3 times higher.

I was trying to point out that my car misrepresents the amount of AC energy used (when doing lots of short trips of about 2-5 miles). I'd argue that out of those 31kWh reported as being used for "driving power" a reasonable proportion is actually spent on AC (maybe 2-4kWh for continuously running the AC for 7h in hot temperatures).

The graph of consumption over the last 50km seems to give highly dubious results whenever I've looked at it. Even at a constant car speed, wind speed, elevation and temperature with no aircon on, it often gives a regular set of significant peaks and troughs.

However I do agree that the graph (such as above) can give a rough idea of the elevation changes and driving style etc, but don't be tempted to infer anything from a single part of the graph.

My best guess as to what may cause the unexplained peaks and troughs is perhaps battery heating and cooling still kicks in regularly even with intelligent battery heating off ?‍.
