Every car as far as I know undergoes cold weather testing and the I-Pace was no different. Jaguar uploaded a video of someone test driving the I-Pace on a snowy course along with Adam Brant, an I-Pace senior engineer, and Adam actually answered the all important charging question. It takes around 45 minutes to charge from 0-80% using a 100kw charger.
Also interesting was this picture posted by Wheels.ca
as there's a red wrapped I-Pace among the green ones.
