You basically described the worst case scenario for an EV...400km...in the cold...high speed...full heat on inside.sounds like a bit of a hassle to me, esp if you have a family on board.
I completed 400km round trip this weekend (up north), filled up the SUV before I left, got to the destination, and back. still a quarter tank of gas left.
no charge stop planning, no unnecesary charge breaks, no worries about cold sapping my battery, I could use all the heat and heated seats and heated steering wheel without worry, no hunting for chargers, no range anxiety, no worries about hogged chargers. I could use higher speeds on certain roads without worrying about battery life zapped in the cold.
smooooooth non stop worry free driving. was a good trip.
Just saying....
We're not at the stage of replacing that ... yet.
However, my max use is 280km in frigid cold (-15C or so) from Mississauga -> Algonquin Park. I can charge at an L1 there for 3 days so should allow for a good portion of the trip back to be done on EV without stopping at a mid-point charger anyway.
Narrowing down to Bolt / Maverick (hybrid) / KIA EV6 / IONIQ5.
Out of all of those, the IONIQ5 is at the bottom for my wife as not enough buttons and she won't enjoy looking for menus while driving. EV6 seems to have more buttons but I've never sat in it.
Maverick and Bolt have the most physical buttons (2025 Mavericks have more of a screen interface with larger screen compared to first gen).
