Perhaps, I was seeing low 4's in the warm spell a few weeks ago. I was generally driving quite quck. So on one tank I intentionally drove for max range and my mpkwh barely rose at all which wasn't expected. Since BMS I have seen more consistent range, but i've found it harder to extract maximum range, which considering the nature of the update is a bit weird.Looks like it's quite easy when the temps go over 20C. I wonder if the tighter pack makes it drive a bit hotter?
