Limiting power?

[blueman671]

In your complaints you revealed driving practices and a driving mindset that puts people at risk..

Erm, no I didn’t. Like I said, I checked the forum after initially posting and people were arguing with somebody else telling them they were a dangerous driver. My last post was made AFTER those comments. So you seem to be conflating my posts with somebody else’s. Suggest you read back a few pages.

At what point have I said I’m better at driving than somebody else? You, along with others, are the only ones passing judgement on specific people’s driving styles. Which is a strange thing to do without seeing somebody’s driving.

There probably hasn't been a more outspoken critic of the the MG 4 on here, my wife's has been a pain in the preverbial but a 0-60 time of 7 secs isn't limp mode and the X Powers 0-60 times in relation to battery % are well documented

Bjorn Nyland tests acceleration Vs battery % on his channel and he took it from 90 - 10% and posted the times, so that info was readily available.

As you say it's a budget EV and they have to save money somewhere on what is quite a cheap price, and limiting power delivery at low state of charge, to protect the battery is obviously cheaper than what some manufacturers do that still get most of the performance at a low state of charge.

I am not defending MG as I would never have another unless there was a dramatic improvement with various aspects of the brand.

That’s a very useful chart - thanks!

Just to summarise before I go on with day:

- Post made about power dropping as charge reduces.

- Issue acknowledged, some denied it existed.

- For some reason some decided to raise the safety issues of a high powered car.

- Hypotethetical scenarios given where this problem would cause a potential safety concern.

- People have concluded based on no evidence that mine and other’s driving is not safe.

- Tongue in cheek comments seem to have upset people.

- Evidence and data now posted showing the problem and to what extent.

- Issue concluded.

If it makes you feel better banding together and labelling me as a hazard, go for it, I really couldn’t care less. I’ve 20+ years of blemish free driving in cars much more powerful and difficult to handle than this cheap Chinese EV.

If hypotheticals get you so up tight, maybe all XPower drivers should be banished from the forum because they could, hypothetically, drive quite fast and break the speed limit.

Sorry to upset you all with my horrific driving. Please do share the footage so I can reach the same conclusions you have.

There is an issue and that issue exists with all ev's as the % drops, I don't think anyone would/could disagree, it has been documented with many brands.
As I've said some manage it better and others, you don't notice it as much in some as the high % 0-60 isn't as fast as the X power and there isn't as noticeable a drip off.
But the X Powers is documented and anybody who is getting the same 0-60 time at 10/15% battery either has a fault or the cars that don't have the same time have a fault.

As it stands I'd go with Bjorn Nyland's tests as being the more accurate reality.

We have common ground. I too do not give a flying fart in a pickle barrel on your flawed thinking.

It seems that, unlike you, I actually did my research before buying this car. I weighed up the pro's and con's and then made my choice. It is not a perfect car, far from it, but it has the best value for the money. I do not fall into the Fan Boy club but I also will not whine about limitations I knew existed before I laid down my cash. Those items, which I know about, can be annoying but I would not claim that any of them make the car unsafe.
Your claims you have somehow been ripped off due to the product not meeting your expectation is absurd. To say that these issues make the car unsafe because you treat the public roads like a race track point at certain level of immaturity and hints at onanist tendencies. You dismiss others here and on the road as being contemptible as they do not conform to your own perverted sense of correct road behavior.
I did not say anything about flying a Jet. I was referring to flying generally, but withing my experience as a private pilot. In the air it is unusual to find another pilot that would cut deeply into safety margins when operating, this seems much more prevalent on the road. If you maintain that the examples you have given above are actually valid I can only conclude you regularly drive close to the edge of your performance envelope, which is a dangerous place to inhabit on the road. This is not just for you but also for the others who share the road, which you seem to hold in contempt.
I am sincerely glad that we are on different continents. In a way I hop you are actually a Troll looking to stir things up online, but I sadly feel you are actually genuine. Though I try not to think too much about you I wonder if this attitude is also apparent in other aspects of your life.

 

[blueman671]

I get that your car may have a fault and you are annoyed by it, ours has had it's fair share and I get that feeling but saying a cars 0-60 time isn't safe because it didn't reach 60 in just over 7 secs isn't a safety issue.
I get that it is less than advertised but it's still the acceleration of a normal reasonably quick EV, as long as you are aware that the power limits as the % gets lower then you drive accordingly. Nobody needs 0-60 times of 3.4 secs just to drive safely.
And it's nothing to do with being holier than thou

For the avoidance of doubt, I agree. At no point have I ever said that if a car doesn’t get to 60 in sub 4 seconds that it’s dangerous.

The chart you’ve just shared shows that the 100% charge 0-60 dash takes almost half the time that a 10% or 20% charge attempt takes.

Some people have commented on this thread that they aren’t even aware of the power dropping! That is the danger here. Someone driving a car that is twice as slow up to the national speed limit as they think it is, WILL lead to misjudgement of a scenario and place people at risk.

Whether that’s a sensible overtake or merge, or, if someone is driving like an idiot (me, apparently?) tries to weave in and out of traffic like you see daily on social media, somebody will end up over committing to a dangerous move they can’t complete - the driver should be warned about this to help avoid the risk.

Maybe some have misinterpreted that as me ‘needing’ to get to 60 in 4 seconds to avoid an accident. Just rushing to be offended by something I suppose.

You shouldn’t ‘need’ traction control to stay on the road. Some people can’t drive powerful cars and are too heavy footed so the traction control function kicks in to stop them binning the car into a tree. Are people that want traction control fitted to cars also dangerous as they’re enabling erratic driving? Or is it a safety precaution?

A visual aid that tells you your car is now 50% less powerful should be a required safety feature.

Again, strange conclusions to draw based on absolutely nothing. Thanks for the psycho analysis doc!

Can you show me a time when I have cut up traffic?

Can you tell me when I treat the road like a race track?

Or have you got yourself upset about a scenario you have made up in your head?

Since you wanted to try and make personal targeted attacks against me, you seem to be the only one with contempt for other people.

Somebody disagrees with you so you start personally insulting them? And yet you think I’m the one that is likely to be an aggressive driver?

Out of the two of us, you’re the one that’s bought plastic Ali express pieces to stick to your car to make it look more ‘aggressive’.

I think you need to calm down.

I stand by everything I said and I predicted you wouldn't hear it. I'll waste no more time on you.

What he said too.

Good. Holier than thou attitude strikes again. You criticised Ollie’s driving and then conflated his posts with mine.

You drive a Trophy so your opinion on the matter is also irrelevant.

Chart has now been posted showing everyone the XPowers power drop off is excessive compared to other EVs so yet more light shed on the MG4s limitations - good for owners and prospective buyers.

Sorry your feelings got hurt in the process.

I think we could agree that maybe there is a specific issue with your car that would be abnormal, yes the X Power like some other high powered EV’s does reduce power in certain conditions to protect battery that is a fact of current EV’s i assume.
I think the comment that some on here not knowing the power drops off is a bit off, yes i know it does it but i usually drive mine in Eco or normal and rarely use anything like the power that it has available thru my choice, this does not make me unsafe.

Based on that chart, no issue with my car. My ‘test’ yesterday produced very similar results so it’s MG’s attempt to save the battery. Just good to know it’s a ‘feature’ not a ‘fault’.

But, there are literally posts earlier in the thread that say the don’t think there is any drop off in power, so either their car is faulty with no battery preservation features or they don’t feel a huge change in their car, both concerning.

Mine is also in eco and energy saving mode 95% of the time. First thing I do is switch on OPD, select eco and ESM

BTW...There was and is no conflation. I know who said what and I did when I commented - it is all above for everyone to read.

You drive a Trophy so your opinion on the matter is also irrelevant.

Wow, what a compelling argument! You win!!?

Sorry your feelings got hurt in the process.

I'm happy as Larry and no hurt feelings here. I think the posts above tell a compelling story about who was triggered.

You've given me a good laugh, so I thank you for that and now I have other things to do.

Enjoy your thread.

Edit: You are in my ignore file now, so I will not see any further posts from you.

Argument? There’s no ‘argument’ to be had. It was a question regarding the extent to which the xpowers power diminishes based on charge %. It’s not an opinion based issue.

So yes, your experience with your Trophy is absolutely irrelevant. Again, sorry if that hurts your feelings.

Also, pretending that I’m ‘triggered’ for raising a question and ultimately being proved right is strange.

‘Triggered’ is a term the chronically-online folk like to use to dismiss people that have opposing views. You may try and belittle me by claiming you have other more important things to do than converse with little old me, but you spend an unholy amount of time on this forum so I highly doubt that.

 

[gary333]

I think it would make sense for performance orientated EV’s to have the equivalent of an electronic rev counter where the power goes around 0-100% and another ring showing what the current limit is. In the power usage screen it could then contain the rational to explain (same for charging) that identifies what the restriction is being caused by. For EV’s it’s probably far more common for lower charge speed issues to cause confusion, but the power meter could be the charging meter when car is charging.

 

[LenEV2016]

As much as I enjoy a wee bicker back and forth and a moan about MG this thread has got a bit off topic, over dramatic and a lot of assumptions have been made that aren't really based on any real evidence.

To get it back on topic I think it has been proved by Bjorn Nylands tests that the X Power does have a bigger drop off in acceleration in relation to low charge compared to other performance EVs.
This has to be balanced with initial cost of the car however and I think most would accept it's a fair trade off!

With this info people are then pre warned that full performance won't be there, however by anyone's standards 0-60 in 6/7 secs is more than sufficient to make progress joing any type of traffic/road situation.

I think Bjorn's figures prove it's not a fault and just a quirk of the car which was the OPs original post/query.

Who'd have thought I'd ever try to be the voice of reason on here, next thing is I'll be sending @Tuareg a Christmas card, to MG Cyprus head office obviously

 

[MG Clive]

I know myself that the power starts to drop off as the battery gets low, but if/when it gets down to below 30%, like mine has today, I know I need to drive a bit more economically, I definitely don't start driving around expecting full power.

The thing is even at 10% in Bjorns tests it's still plenty fast, faster than a trophy!
I think being pre warned about what to expect is the issue.

Yes, it does seem to be more noticeable with XPowers than other cars.

I agree.

Yes, that's clear.

I think Bjorn's figures prove it's not a fault and just a quirk of the car which was the OPs original post/query.

And we discussed this at length above - the XPower was a quick afterthought by MG with minimal hardware upgrades to provide a pocket rocket, which is a lot of fun to drive.

But the downside is that they didn't uprate the battery or cooling system for the battery/motor, so power limiting kicks in.

As I mentioned earlier, I also think driving style has a direct effect on people's experiences.

If you are someone who basically drives normally but enjoys your XPower's potential from time to time, then you'll probably not notice this much - your battery and motor temps will not be elevated much.

If you are someone who hoofs it all the time and drives like you stole it, then you'll likely see this much more often as the car components get hot.

Now, MG don't warn you about this - so I agree that if this is an unwelcome surprise then people have a right to complain about it.

Who'd have thought I'd ever try to be the voice of reason on here, next thing is I'll be sending @Tuareg a Christmas card, to MG Cyprus head office obviously

Stranger things have happened!

 

[blueman671]

Just like to add that I’ve checked the ‘Cars you’ve smoked’ thread and am shocked to see some of the hypocrites that have accused me of being a reckless driver bragging about how quickly they overtake slower moving cars on multiple posts. Multiple people.

To the idiot that called me an onanist and claimed I held contempt towards other people, why are you using the “BLAT” pedal and ‘leaving people in the distance’ when you pass speed cameras? Are you using the road like a race track like you accused me of? You absolute whopper.

Spend less time editing your profile photo like a teenage girl and more time being considerate of other drivers. Calling me an onanist when you’ve slapped plastic trim to your MG and photoshop pictures of it on the internet is hilarious. Does your Mrs think it looks cool? Or are you the onanist among us?

The audacity .

........I think Bjorn's figures prove it's not a fault and just a quirk of the car which was the OPs original post/query...........

Yep, I think that Bjørn Nyland video in post #40 on this thread is a must watch for all Xpower owners and I'm glad I watched it when it first came out in January 2024 (when it appeared in the similar thread below) As well as highlighting the big power drop off at low SoC he also gives advice on using Sport mode to keep the AWD on permanantly in slippy conditions.

Highlighting and spreading this knowledge on the forum is what the forums are all about and I learnt so much here early on in my ownership on here.

A similar topic was dicussed back in late 2023 too on here in this thread with the above videos and tables :-

Thread 'XPower feels slow and launch control not working'

Nov 30, 2023

Not sure if this is related to outside temperature, or battery temperature levels... but my XPower feels slow all of a sudden and I cannot get it to trigger launch control either. Feels like a sub-8 second to 60mph car instead of a sub-4. Even when you're rolling if you floor the peddle it just doesn't really get up and go.

Anyone else experienced this? Googling it wasn't really fruitful.

Feels like a standard MG4 rather than an XPower.
