Happy with my range.

[Walespete]

Did a 150 mile round trip on Friday. Mostly motorway, temperature 4 or 5 centigrade, heater on. I didn't go above 60mph.
The car went from 95% to 14%, leaving me with 25 miles range.
Did the same trip 2 weeks earlier, same temperature, but I did 70mph. I needed a top up to get home.
I hhink that's good for a 4 year old MG4. It also shows the big effect on range slowing down a bit makes.

(Your MG4 won't be 4 years old ... 3.5 years at most)

But yes - speed is a big factor in overall efficiency, as drag change is proportional to the square of the speed change. (e.g. double your speed and the drag will be 4x higher).

You're right of course, 3½ not 4. I was never good at maths.

Yes it's mainly the aerodynamic drag that's the issue along rolling resistance etc.
An EV at 70 mph will roughly consume 17% more power than at 60mph.
Assuming 3.5mls/kWh, then at 60 mph, power consumed = 17.143kW. At 70 mph then the power = 20KW.

This is also more apperent with MG4, as it has pretty weak aero. So you get penalized more when driving faster, than other, more aero friendly cars.

But if you eliminate aero (or reduce it effect a lot) by doing the hypermile behind the lorry type driving, car gets very efficient, especially with proper LRR tires.

Yes its disappointing that the MG4 looks like it would be aerodynamic but doesn't perform any better than rivals and in many cases seems to be worse. Same drag as the MGS5.

The Kia EV3, Skoda Enyaq and Cupra Tavascan are lower drag coefficient despite being SUVs.

 

[EvTek23]

That's surprising that the EV3 has a better drag coefficient than the MG4 (0.26-0.267 versus 0.27-0.287) as the EV3 looks so bluff at the front.
I also a reference to power versus speed by @Fogey back in Nov 2022, the thread was called; MG4: Drag, Various Conditions

I did a 100 mile round trip to my daughters the other week, heater on 21 degrees, heated seat on some of the time, a mixture of 30, 40, 50 & national limits (all A roads), averaged 40mph over the trip with the occasional 'blast' in sport mode, from 100% got back with 42% which I was pretty pleased with.

 

[MattyS]

I've just charged to 100, and achieved 196 miles, ac on all the time, heated seats most of the time, some night driving, temps around 6-9⁰c

Good to hear a positive post

Contrary to popular belief. There a loads of positive posts.

Seems to me that MG's fall into two types.
1. Totally reliable, the majority.
2. Absolute mingers! The unlucky few.
This forum has a disproportionate number of dissatisfied owners because you are more likely to post if something is wrong.

As for my MG4, it hasn't missed a beat. Only issue is the iSmart app which doesn't work. Doesn't bother me.

For a possible fix for the app, would recommend trying two things. 1. Uninstall the app, reinstall and rebind. 2. Try installing on a different phone and see how you go. Maybe try Android vs ios

To do that you'd have to unbind first before uninstalling the app. The car is bound to an Account and not to a Device.

I recently bought a used MG4 and it was bound to the previous owner. The procedure was very easy, scan the QR code on the car infotainment system, get a prompt to unbind, wait 72 hrs (to stop some nefarious person trying to unbind your car if it’s still yours..) and voila, you can now bind it to your own account.

All of the communication is recorded in the app too.

I personally find the app very usable, the only quirks are if you want to schedule a charge, ensure you remove the schedule on the car infotainment system before trying in the app. Bizarrely the car infotainment system reads the same schedule as inputted in the app but you must to it this way round.
Also, you have to refresh twice normally to find the proper status of the car. But no hardship really.

The remote climate control and location finder work perfectly for me.

It is the first car I’ve had with an app though so maybe the novelty hasn’t worn off for me!

The app doesn't work on my car. It sometimes connects when it's charging but doesn't when not, unless I'm within 30 feet of the car.

Ah, got it, thats a shame as the app is useful. But its not a deal breaker, I could live without it as you have said too.
