Question about round trip from Yosemite to Mammoth: make it without charging?

[7414]

Forgive me if this has been asked and answered. I have a Model 3 and want to drive round trip to Yosemite from Mammoth. Will I be able to make it round trip without charging if the car is charged for 310 miles of range?

Answer: it depends.

I recommend using the EV Trip Optimizer app for questions like that.

Looks like it's possible.
Also Ahwahnee Lodge has Tesla charging in the valley

Possibly, but why not spend a few minutes at the Mammoth Lakes Supercharger. Then you arrive back with some cushion.

I will be starting the trip by leaving the Mammoth Lakes Supercharger with a full charge.

This doesn't look right. Is it 179?

Yes, that does look odd. I just checked it again and it still says 79 RM used.
Given the elevation change, this may be an error.
Best to check with the trip planner in the car.

I just checked this route with abetterrouteplanner.com and it gives 328 wh/mi so 33kwh for the return from the valley. This is probably more realistic. Still looks doable especially if you can pick up some additional charge in the valley.
If you end up short when you get back to Lee Vining, you can jump up to Gardnerville SC
