New MG4 EV (2026 facelift) - Now on MG website

I thought these cars had zero emissions?

You must hear of the prank, you let off one of your own emissions, then ask if anyone else smells petrol ....... Naturally, they all take in a deep lungful through the nose Now that could be classed as a daft emission, it being an electric vehicle, yet they all fell for it .....

Indeed

• Rear seats lighting
• Intirior mirror lighting
• rear armrest
• Intirior handles (over the doors)
• Windows auto close when looking the car
• Walk away locking
• sunroof as option
• ***** full OTA capabilities *****
• Maybe improved MG pilot, like in China.

Deshboard & doors ambient lighting also will be nice, all the Chinese brands have this today.

Ambient lighting would be one of the last things I'd want in any car, it's a fashion thing which definitely won't influence my purchase, but what would influence me are simple, practical additions, like being able to see the 12v battery state of charge or at the least voltage state, it was on my previous MG4, but as mentioned loads elsewhere not on my S5 trophy.
Was-on MG?

Ambient lighting is definitely not a necessity. I just think it's great, and really lifts the interior. Each to their own

We've got a mk8 golf on hire here on Lanzarote @salty , it has ambient lighting, it's nice, but as you say it's not a necessity.
At home I'd prefer being able to read my 12v battery voltage on my S5 over ambient lighting, given a choice of course but we have neither

12 v battery voltage readout isn't a concern on cars that aren't having issues with their 12v

Absolutely spot on Len, we shouldn't even be needing to talk about it!
So get things done MG and we'll all have ambient lighting

Yes, 64kWh version of the new MG4 is LFP, interestingly with a HIGHER max charge rate than the former NMC version. Not sure what the cold weather performance will be like though (generally weaker with LFP), but still charging to 100% all the time would be nice. This is very likely to be a new generation of LFP battery with improvements.

The ER 77kWh is NMC as is the 64kWh X-Power version: the X-Power requires NMC to get the power draw levels required to drive both motors to the max. I presume a 77kWh LFP pack would be unbelievably heavy and so that is why they stick to NMC there.

@tsedge, also MG are quoting the same top speed for both the Premium Long Range and Premium Extended Range at 112 mph, while the old Trophy was quoted at 99 mph, and the Trophy Extended Range at 112.
The power is also less in the new Premium Long Range at 190 bhp rather than 203 of old version, the Extended Range remains the same at 245 bhp.

 

[T1 Terry]

Well, it won't be an XPower facelift model on my shopping list .... an abandoned battery chemistry, cast rear suspension and drivetrain component that is not repairable ..... skip the yeah part, just nah, not for me thanks

That suggests perhaps a change of motor or gearing or maybe they are just more confident it will sustain higher speeds (the improved aero could also be the reason).

Is the weight different? Be interesting to see if the performance is affected much.

I think you have got yourself mixed up with the IMs and the cast rear suspension etc.
NMC isn't an abandoned battery chemistry new and improved versions continue to be developed it is still the battery of choice for all long range cars and high performance cars, as it can sustain the power delivery better
LFP has come on leaps and bounds but still isn't as energy dense so is still a heavier pack relatively.
Yes it is slightly safer chemistry, can sustain more charge cycles and is cheaper, therefore it's is being used more in reasonably priced cars where budget counts.

LFP also suffers a lot more in cold temps, not an issue for yourself, but certainly a consideration when you look into it's use in northern Europe

 

[EvTek23]

@tsedge, Old Trophy Long Range is quoted at 1675 kg, new Premium Long Range quoted at 1765 kg.
Old Trophy Etended Range quoted at 1751 kg, new Premium Long Range quoted at 1755 kg.
So the new Premium Long Range is 10 kg heavier than the new Premium Extended Range.
The model that has really put on weight is the Premium Long Range which is now 90 kg heavier than the outgoing model. The difference I guess between the weight of the LFP 64 kWh battery pack versus the 64 kWh NMC battery.

Thanks for doing the fact-finding. Yes, LFP is heavy.... but much cheaper to make. My guess is this is all about hitting the sub-£30k starting price for the new MG4 EV.

That doesn't mean it is bad though, will be slower but you can use the whole 100% whenever you like without worrying.

China has banned any chemistry battery that can self combust, in other words, make it's own oxygen when thermal runaway occurs, and chemistry with cobalt in the mix is going to suffer this problem.
Unless you know of a company that can compete on price and manufacturing volume that isn't in China, then I'll accept defeat yet again.

Sodium ion does not suffer with low temp problems, down to -40C, NMC or any of the ternary lithium ion cells or LFP suffer loss of capacity and shorter cycle life operating in these low temps.

As you can see, Na+ (Sodium ion) out performs the 3 chemical mix lithium cells in capacity retention and discharge rate, NMC is on the extinct battery chemistry list .....

Sodium Ion is also yet to ramp up to significant volume and manufacturers keep lines running for years. Many European makes have only recently started to use LFP. So while it looks much better for medium-to-long-term to go Sodium, this will take years and years to play out. Solid state will also have something to say about this - may replace NMC at the high end as Sodium replaces LFP at the low end.

PS: Oh, and LFP is not fire-proof: it is just much lower fire risk. It is all about statistics and what you consider to be safe.
