The 327 miles range will be what the manufacturer thinks it’ll do so you can forget that 🫣
Your 100-0% 140 miles, how are you calculating that? Have you actually driven those miles or is it a couple of short trips and extrapolated the range from there?
At a quoted 327 mile range you’d probably get about 275 on a single long trip, if you only do a 5 mile commute twice a day in this cold weather then yes 140 miles might be what the car thinks it’ll do ☹️
Can I also say to check your tyre pressures cause they’ll have dropped in the cold and that can have a big effect on range.
My Ioniq 6 is getting about 260 miles just now in 30 mile sections.
