Changes to Models S and X allow them to travel longer without larger batteries

1,000$ of batteries = 1kw of resistance heating for ~8 hours and that’s improving over time.

Now, I am not sure how much reserve heating you want, but it’s much closer than 10x cost wise.

3-4h 1kW heat sounds reasonable. If that's less than say 3% of total range, or less than $1k extra battery then I'm confident it's a sufficient solution.

Model 3 users report using about 240 to 300 watt-hours per mile. So I think that means a 1KW heater for an hour is equivalent to about 3 or 4 miles of range.

So a 1KW heaster for 4 hours would lose you 16 miles of range.
