Is my MG4 miles/kWh trying to gaslight me?

[gdog]

I know the mi/kWh in winter should be worse. But since my last charge to about 80%, it estimated about 3.4 miÔ/kWh and I had covered about 50 miles and it was about 38%. I then charged to about 86%. Just didn’t sound right to me so I broke out the calculator.

Ok so I charged with 29kWh and deducting 10% for losses this is about 26.1 kWh added.
I’ll take 6% off to estimate charging to same level. 1%=26.1/(86-38) & 6%=3.3kWh
So I used 22.8kWh over 50 miles = 2.2 miles/kWh.
I guess that not too far off? Only 33% over estimate. Looks like MG are doing a bit of gaslighting. *** everyone is at it now. Can't even believe my car.

How have ther rest of you found the guessometer miles/kWh?

This time of year, and the fact I do a fairly short daily commute (less than 10 miles) then 2.2 miles/kWh sounds about right. I visited family at the weekend with a 240 mile round trip and got up to 3.4 miles/kWh on the way there, and 3.1 on the way home.

We have never gone into it in depth. We get at least 200 miles per 100% charge. LR Trophy.

I am currently getting approx 2mi/kWh.
Mind you this is at 3am when I commute to work

 

[tsedge]

2mi/kWh is the minimum displayed, it won't show less than that even when it is less.

So I have noted all charging and usage since I got my MG4 Trophy (2022) and this is the actual electric used from the charger, not the GOM, so in summer it is around 3.5km/kWh and winter it is around 2.5km/kWh (all averages and I have done 13,000 miles). Shorter journeys in the winter not only affects the battery but you have to warm the car up as well. Shame it is not fitted with a heat pump but Oh um.

The GOM in the winter seems about 208 miles and summer about 257, both these figures is around what I can get in reality.

I find the GOM is fairly accurate until you have a sudden change in your normal driving. So when I potter around town, short commute etc, the GOM is pretty spot on, but if I go for a roadie and do more highway speeds the GOM seems to take a while to figure out what’s happening. It takes a bit of forward planning, and early charging where possible, as suddenly the GOM figures it out and you are without range.

Funnily enough it then takes a day or two of pottering before the GOM goes back to “normal” driving. It seems to base its calculations heavily on historic performance, and not so much actual/current consumption. But I might be wrong in thinking that of course.

Sounds about right. Bit low in summer. The GOM is definitely gaslighting me.

Seen some real world comparisons of BMW i3 EVs between heat pump and non-heat pump models in UK winter and the heat pump model was not much more efficient..

Remember, those figures are actual charge figures from the wall socket, not the car which (wall figure) will be higher due to charger inefficiencies (7.1kW in, 6.5 kW into the battery).

Just check intelligent battery heating isn’t on - it sure does gobble electrons

If you look at my calculations they allow 10% for losses

Its amazing how many people dont understand the term “gaslighting”.

“the action of tricking or controlling someone by making them believe things that are not true, especially by suggesting that they may be mentally ill:.”


You mean plain and simple lying

Well "lying" sounds a bit dull TBH. But MG are indeed trying to trick us into believing an untruth. But there was no suggestion of mental illness from MG TBH.

I've come to realize that I get nowhere near what the 'guessometer' states, no matter how I drive, even after resetting it to zero after each charge.

 

[Phil]

Getting 400-420km in my MG64 here in Oz. About 4.1 miles per kWh(Summer), drops to 360-380 km in winter.

 

[Coulomb]

Especially if you zero the trip meters after each drive. That clears the winter performance from consideration, reverting to optimistic factory figures.

It just doesn't make sense as a power meter, it's only a possible rangeometer, according to how it's driven. To get a more realistic range balance, I reset the odometer/mileometer every hour or so, I also find this an ideal way to negate the ulcer - creating 'range anxiety' inherent on longer journeys.

The GOM mi/kWh is overestimate IMO to make us feel better. The range has been pretty accurate so far

3 mi/kWh is my normal winter worst reading unless it's a very short run
