I don't know how they come up with those EPA ratings. Can only guess that Hyundai was very conservative, while Tesla used best case hypermiling type conditions. It could also be that because the Tesla EV motor has more power, it is easier (more tempting) to consumer more electricity with that power. I use ECO mode which is definitely more economical than Normal or Sport mode. But I am not missing anything as far as how fast I drive or how I drive (staying with traffic flows). I like ECO mostly because of its "one pedal" driving with its stronger regen.
There are actually a lot of things that I like better about my Kona than my son's M3. The Kona seats are way more comfortable with its perforated leather and active venting capabilities. The M3 leather seats are hard and slippery, and you get a sweaty butt after a while. Getting in and out of the M3 is not easy either, with its very low seats, and you really have to duck your head to get below the top door jam as you slide in. And that centre monitor is stupid. My son can't drive for 5 min without checking and poking at it,... a real distraction IMO. AND he can't use the free BC Hydro DC fast charge stations, only the Tesla SuperChargers if he wants a fast charge (not free for the M3).
