i get 370-380 in the winter on 20in wheels, 400-420 on 22s
in summer its about 350 on 20s.
its all heavily dependent on your foot n top speed.
i just had a best trip on the way to work in 45deg weather almost matching EPA. key was driving 65mph n below.
this was 331Wh/mi (epa is 324)

i always set mine to 69-70 with 3-4 fan speed
i consistently get less than epa for 'climate' consumption as u can see in above screen shot
so don't think heater matters that much as long as u not blasting it full speed
when we had freezing rain here n i was blasting it to defrost the windshield, yeah it consumed a lot of % on the same drive home
