This was actually something I was rather shocked with on the Tesla Model 3. I never, ever get anywhere near the EPA range on ICE vehicles I’ve driven, but in the TM3 I can regularly beat the rated Wh/mile efficiency.
With two caveats. One, if outside temperature is below 50F and I’m running the heater the efficiency drops a bit at higher speeds and significantly in heavy traffic (because heating is per minute not per mile). And two, even though the electrical efficiency is better than advertised, the MPGe conversion is not accurate because electricity costs are artificially high in MA.

Having an insulating layer between the inner and outer steel panels and maybe making all glass out of a laminate with the inner plastic layer something thermally insulating would help a lot.
- Brakenshire 8y agoThat’s a good point.
