Hi all - first post.
I've spent a while lurking here and on other I-pace forums, reading about range, the G-o-M and a bazillion other topics around how good or bad the actual / perceived range is. Thought I'd chime in with 6 months worth of real data.
Background - I'm a British ex-pat. I bought my MY2020 I-pace in July. It has the 20" wheels and (it seems) the H264 update (I'm guessing as I have the new linear battery meter in the display).
I have driven since day-1, "like a car" - ie with absolutely no concession to it being electric. This was a deliberate choice. I've had it in 'comfort' mode the whole time, with A/C or heating on. Right foot is moderate - not a hooligan but not an OAP. No pre-conditioning. Plugged in once a week to my 7kWh wall charger (to 100% charge) and once a month it gets some sweet sweet free 50kWh loving from a free Chargepoint station near me (to 80% charge). It's kept overnight in an unheated, badly-insulated garage so it gets pretty close to ambient temperature.
Location is Salt Lake City in Utah, so driving in the valley, mostly, which means little elevation change going north-south and major elevation changes going east-west. Driving is about 80% urban (with the plague of American stop signs and traffic lights every block) and 20% motorway. Two or three long day-trips into the mountains which involve a climb up I-80 which - here - is where U.S car makers frequently kill their test mules because there's an uphill section of I-80 which is murderous to cars in the summer if they're not in good shape. From where I am to the I-80 summit is 14 miles and 3000ft increase in elevation.
Because of COVID and work-from-home, most of my trips are pretty short at the moment - to and from shops, drive-throughs and the occasional trip to my office.
Anyway - at the end of the year (ie. now) I downloaded all my trip data from the InControl website, and spent an hour or so in Excel crunching the numbers and trying to get something faintly usable. I don't know if this sort of thing is a PR nightmare for Jaguar or not - I don't really care. I love the car, I'm growing to accept the mileage limitations, and I think that "that other brand" is full of it when they talk about their range (from knowing 8 owners who are getting barely 50% of the claimed range in real world conditions in their 3's and Y's).
Here's my real-world data:
July average kWh/100 miles : 39.7, theoretical max range 226 miles. Average temperature 30C to 35C
August average kWh/100 miles : 39.3, theoretical max range 229 miles. Average temperature 30C to 35C
September average kWh/100 miles : 41.0, theoretical max range 219 miles. Average temperature 25C to 30C
October average kWh/100 miles : 43.5, theoretical max range 206 miles. Average temperature 15C to 20C
November average kWh/100 miles : 55.5, theoretical max range 162 miles. Average temperature 0C to 7C
December average kWh/100 miles : 63.6, theoretical max range 141 miles. Average temperature -5C to 2C
What's interesting is the the G-o-M is always wildly off. Right now, in December, on a full charge, it claims 244 miles which I can't even get in the summer. More interesting is that if I use Jaguar's own online range guesstimator, it actually comes pretty damn close to the real-world numbers I've observed in my own car.
Conclusion 1: the I-pace is happier to be in hotter weather with the A/C going than it is to be in colder weather with the heating going. Seems about right as a general statement about batteries.
Conclusion 2: WLTP is an absolute joke. It's worse "guidance" than the old EPA gas-mileage numbers for ICE cars. About all it's good for is comparing EVs to each other. If one EV has a higher WLTP range, it means it has a higher real-world range. It doesn't mean you'll ever actually achieve the WLTP range.
If anyone is curious to see the raw data, I can probably share the spreadsheet on OneDrive....
