Rule of thumb is that 1000' of climbing burns about 10 miles of range. So theoretically, it would require 270 miles of flat range to get there (pass at ~7000'). I would expect stopping in Auburn or Colfax for a quick top up.
Suppose the question is whether R2 flat range is in line with EPA. I find for my R1S that it is and get into Truckee a comfortable margin. Whether that's also true for the R2 based on recent tests is more debatable

I would not rely on official range based on what we've seen. I suspect that at normal speeds R2 will require a stop in the way up.

Seems like a not insignificant factor in addition to altitude gain will the speed OP drives on the freeways? I presume ABRP assumes driving at legal limits, which IIRC are mostly 65mph apart from I5 on the Stockton-Sacramento stretch.

However, if you're driving at 80mph every opportunity you get then its questionable if you'll make it, if driving at a more mellow 65mph then perhaps achievable even with winter temps. Although in the latter case, as already stated and acknowledged, one wouldn't choose to push it if there's even the slightest risk of bad weather.

The interesting thing is that ABRP shows a similar result for the R1S and R2. I know from experience I'll make it with the R1S going 70-75 mostly

This is my rule of thumb for R1 too but maybe it will be slightly better for R2. Hm, maybe not.

My math says that the physics required to lift R2 to 7000' above sea level is very roughly 14 kWh, which is 16% of the battery pack. So the absolute best case scenario here is like doing a flat 200 mile drive on 84% of the battery.
