Sudden jump in Estimated Range??

Hello,

I am not delusional enough to believe that this is true, but for the last week or so my range estimation at full charge is saying 280 miles. It seems to become gradually more realistic as I drive, but still well inflated beyond what I believe to be true (at 77% charge, still reading 239 miles).

Makes an already sketchy range estimator seem extra sketchy. Not sure how to rely on it.

Recently got a software update at the dealer. Anyone else seeing this glitch??

Thanks.

Seems to be a common problem. I have it too. If I switch to ECO my range actually goes down now. It makes... no sense...

Until a week ago (and I've driven 3 I-Paces over the past 8 months) ECO mode ALWAYS raised the range on all of them. Now it does nothing and I'm pinned at 201 mi range at 100% SoC. Not too bent out of shape over it since I have enough experience with the car to know better, but it sure is odd, even a bit annoying how little the range varies, even with ECO mode or use of AC.

See my other thread. In my car if I go to the eco panel, it says if I turn AC off it will give me an extra 130ish miles...

I decided to switch my regenerative braking from high to low the other day. With high regen, I would consistently see 201 miles @ 100% SoC. Now, with regen set to low, I'm seeing numbers that more closely reflect the car's claimed 240-mile range. I checked the car moments ago and it showed 213 remaining miles on 84% SoC. The SoC number magically grew overnight from 81%, though the vehicle was at no point plugged-in. I love that I'm gaining range, but I'm none too confident in what the Jag is telling me here.

Has anybody seen a difference in ECO mode WHILE driving on the highway. Or, is it only "in effect" during acceleration (which is markedly retarded in ECO)? I tried a 10 mile test maintaining 70 MPH on flat ground for 10 miles in ECO and 10 miles in Comfort, and they both seemed to use the same 5% of battery.

I think the only thing ECO really does on the HWY is limit HVAC

Ah, so maybe if I went longer, I'd see a difference ... ? The problem is that I live where it's still hitting 107. Every day.

At a constant speed, the amount of energy required to maintain that speed will be the same irrespective of mode.

I notice that ECO gives a more gradual throttle response that I actually prefer for around-town driving.

Update: with regenerative braking set to "low" I now have 282 glorious miles at 100% SoC, as opposed to the 201 miles I would see with regen set to "high". I'm going to run the I-Pace down towards 0%, see what my actual mileage is.
