This thread is very interesting, but for it to make any real sense it would help if everyone could do as @Phaedra has done and state real world range versus quoted range e.g. “Quoted range of 327 at 100% charge, real world Jan to March 220”. Miles per kWh means absolutely nothing to me ?
Miles per kWh is pretty much miles per gallon for the EV world. It measures efficiency, a much more realistic test of what it costs to drive the car, rather than which manufacturer can squeeze more battery capacity in/under their cars. I always work out what I’m actually getting per charge by multiplying the miles/kWh by the charge quantity rather than what the Guess-O-Meter reads. My last charge was 70.8 kWh and I was averaging 3.4 m/kWh before that recharge. That means from 90% down to nearly empty I did 240.72 miles in a mixture of short trips around town and a few longer ones either on country roads or dual carriageways.
This measure quite realistically with a 100% use at 263 miles range. As things warm up, I’d expect nearer 300-320 miles which means 4.1m/kWh and a 90% range of 290 miles.
WLTP quoted ranges are usually nonsense. However, Hyundai have a history of getting rather close, if not better than the quoted range. The original 64kWh Kona was quoted at 320 miles in summer, I was following a thread on an EV chat group where people were getting between 300 and 340 in August and one even managed 380 miles, probably by driving extremely carefully and using every trick in the book to extend range. The range for the RWD Namsan Edition Ioniq 5 is 296 miles, as you can see I’m not far from that and the temperature is barely in the teens. At 20-25C I’d would expect well over 300 miles if I ran the car from max to nearly dead. Oh, and I tend to drive comfortably, so air con on in the winter, heated seats (x3) and steering wheel on for most of the time as well. In the summer, I’m expecting heated seats to become cooled seats and air con on freeze as none of us like being too hot, we’d rather contend with being cold and having to warm up a bit. I also pre condition every morning I have to take the Mrs to work, so 3 mornings a week it’s air con on and the car going nowhere AND not plugged in. That’s no good for range.
