Range prediction - if only

[Rolfe]

Why do you have the range in Milliliters? (mls)

I guess getting about half a pint at the end of your trip is OK.

That annoys the hell out of me too.

I don’t know, I suspect the car’s software just goes “I don’t know anything about your driving so here’s what they’ve told me to show you” (WLTP or whatever formula SAIC uses). But that’s just my guess

If it was doing that, it would be telling you 218 miles.

No one noticed the 14 mph average ..... I've never tried to drive that far at an average of 14 mph, so I'm not going to say it's not possible for an MG4 51 to achieve .... but I'm certain I couldn't do it

The trouble is, that's meaningless. If the car is stationary but turned on, it counts that time in its calculation.

So the average speed is more or less meaningless than the guessometer?
The only value I've seen in the guessometer, is the numbers go up when in regen going down the long hill into Adelaide .... the SOC doesn't go up .....

On the return trip, the guessometer really drops like a stone climbing big hill, giving the driver the feeling it won't make it much further, that was the effect it had on the sales person who had it as their demo drive car for a few weeks before we bought it, he turned around and drove back across the city to get another vehicle for his drive to Murray Bridge, 74kms away .....
Once it clears the first hill, all the guessometer distance returns ... plus a bit ..... but it was great value when it won me a bet (for a meal of my choice) we would make it home with range to spare, rather than driving into Mt Barker to a charging station

If it was doing that, it would be telling you 218 miles.

It somehow gets very optimistic when it resets, I think my car shows something ridiculous like 485km even though the WLTP is 435km. I think the standard used in China is CLTC which is known to be much more optimistic than WLTP. Again this is just thinking out loud, I don’t have any proof for this.

 

[Rolfe]

Mine doesn't do that, it does the 218 miles thing.

You need to learn to understand what the GOM really means. I used to watch the GOM on my old Golf a lot, so that helped.

You should see the nonsense it displays after the car hasn't moved for 48 hours, having been switched on for over 30 of these hours (me sleeping in the car). A couple of times I reset it all in sheer self defence.

Interesting to see real world range tests.

Not a new video, but 12 cars driven in reasonably average conditions for the UK (raining and about 11 degrees C) and at various speeds to simulate town/motorway driving.

MG4 faired reasonably well, Trophy ER managed 227miles (70% of it's claimed maximum) and 80 miles more than a Lexus costing more than twice the price !!

Also interesting was the fact its claimed efficiency taken from the car was its actual efficiency 3.1m/kw
