Every single head to head I've seen that puts the I-Pace against a Tesla, has the Jag come out on top.
Range, Availability of rapid charging, early-Taper during rapid charge, low capacity of onboard charger are all negatives for Jag in my book, and there are unknowns such as battery degradation and whilst reliability is expected to be good, from Jag, this is a brand new project for them so may well be some unknowns.
Lots to like about Jag, but to think that its a slam-dunk compared to Tesla is, I think, naive. Jag is pushing back delivery dates, back tracking on allowing test drives, which all looks a bit knee-jerk to me.
Also lots of happy Tesla drivers ... the horror stories are the ones that make the press, and plenty of people also have those about Jag in general. I personally think that Jag makes, on average, nice cars of good quality, but that hasn't been everyone's experience. Same with Tesla. I had zero defects on collection, and have had nothing of that nature to complain about since. I have had a fault on the beam headlight, but that is the only significant fault in 50,000 miles of motoring (other than long time to make a service appointment, and other growing-pain support issues), and amongst Tesla drivers I know I'm not alone ... so stories that quality is 100% rubbish are definitely not true. Not to say that it couldn't be improved, nor that there are not some/or more quality complaints.
A significant problem with EVs is that they are so quiet that all sorts of noises and rattles, which would go unheard in an ICE, are an annoyance that requires a service visit to get fixed, and that mucks up the Stats too. I had a windscreen replaced (stone crack). The normal AutoGlass people did it, and after a week I had rattles and squeaks and decided there was no point getting Autoglass to fix it as I figured that they might not know how, so I took the car back to Tesla and their fix has been fine ever since. Maybe Autoglass could have fixed it too ... I didn't ask them to try. These are all new problems for established ICE, but newbie-EV, makers to have to learn how to solve
