Limiting power?

[salty]

To be fair, the same thing happened on my Ioniq so I'm not too concerned, it just seems to be that in the MG4's case it seems to give less power as it goes below 60% (maybe even slightly higher).

WOW, losing power at 60% or even higher is bad. Perhaps there's summut wrong with your car.
I can honestly say that, I don't feel any noticeable loss in power, even below 20%
in my X Power. Possibly there might be, but it's not really noticeable, coz it's still quicker, than most cars, even below 20%.

If it's below 60% and very cold mine loses power. If I slap it on a rapid charger for a few mins the performance comes back and stays back for the remainder of the drive.

Low SoC and cold really kills the MG4, it's more apparent on the XPOWER.

Fair enough, your obviously experiencing,
that with yours. I just don't seem to be experiencing it with mine. For example this morning it was -2° and 30% battery, it still felt bloody fast.

Did it say 100% power on the dash when you floored it? I can promise you it won't.

My arse-dyno is quite finely tuned too.

The XPOWER isn't the only car I've owned with this sort of power - I've had petrol cars with this level of punch.

To be fair I've never noticed, to busy hanging on. But I'll definitely make a point of looking, next time I floor it.

If the car actually let you know when it’s limiting power that would be good. Some sort of visual indicator that you don’t have 320kw at your disposal would be great.

I would assume that 'maximum available discharge power' data is available via an OBD2 reader like car scanner? Not sure about MG, but that data is available for some EVs.

Seems like a sledgehammer to crack a walnut type solution.

They're not that quick!

They are to me. Quickest thing I've ever driven. And like you I've had some "fast" ICE motors.

Bear in mind i am not talking about going from 200bhp to 100bhp. It's just there is a difference. I drive my car hard, so notice it.

Well and bikes.

Even what I have right now on two wheels is quite a bit faster.

Can't argue with that, fast bikes are summut else.

Well seeing as the fastest car I've ever owned was a mk2 Fabia vRS, 180bhp and a 0 to 60 of 7.5s, I'm expecting to feel a big difference with the XPower.

You will. I too had an 180 ish bhp. Fabia vRS. Bought brand new in 2003. Lovely motor!

The mk2 (mine was 2012) with the 1.4 petrol, being turbocharged and supercharged meant zero lag and the DSG box was so smooth, if it wasn't for the sound of the engine and the rev counter movement you wouldn't have known it had changed gear.

That’s my problem I think, I’ve had faster petrol and diesel cars so am accustomed to the power, making it more noticeable once the mg gets restricted.

I might do some test runs and record what G’s the car pulls on acceleration at 80% and 30% as that’ll be a good indicator.

It’s actually quite dangerous I think. You get used to your car and know what gaps you can and can’t slip into. Going to switch lanes or overtake and suddenly losing half the car’s power is a recipe for disaster. Already caught me out on the motorway when i put it into sport and went nowhere when planting my foot.

Oh well, like someone said, you get what you pay for. Just a shame I could’ve paid less and got more if I went for a different brand. Lesson learned.

Be good for someone to test this under controlled conditions.

The standard battery and standard cooling system are going to limit motor and battery temperatures and power outputs in different situations.

There's an entirely separate question of whether anyone needs to deploy 100% of an XPower's power on the public roads, but I can understand wanting to get what you thought you were paying for.

Edit: what is the cheaper alternative you could have got instead?

I absolutely need 100% of the power to get past the gloits that don’t know how to drive and get on with my day.

I’d be a safer driver doing 150mph backwards whilst blindfolded than half the idiots I see on the road. Saw someone yesterday scrolling through tik tok whilst driving.

I would’ve overtook him and got out of harms way but my XPower was low on charge…

If you go to 5'30" he discusses the drop off in power ... seems to be at 20% and lower that is most significant for him. Keeping it in Sport mode helped him as well I think but it was cold testing conditions !!

If your drop off is occuring at a higher % I wonder if a good 10%-100% slow AC charge may recalibrate the battery software thingy (as recommended once a month is it ?)
