I collected the reported ranges (in km) for the Ioniq Electric I have seen up till now and put them in the scheme below given both in km and in miles, depending on the two main determinants of the range: temperature and speed.
If more experiences are reported we can replace more X's by numbers. For example, drivers from South Korea may provide input to fill the lowest row completely, and drivers in North-West Europe may have input for the highest rows. Please share your experiences with us (and indicate the average speed and the temperature).
