Model Y Long Distance uphill driving

[Cjberg]

Efficiency battery range question:

Today I'm leaving on a trip that is 169 miles to destination. My Y says it has 320mile range. Sounds great! Except it's an up hill grade nearly the whole way as I love in low desert and traveling to a river resort in Needles, ca.

There are no charging stations between me and it.
Can I make it?? Should I take direct route Tesla says to and trust the car??? Or should I go the longer way , 75 miles uphill thru morongo valley, & stop in twenty nine palms - recharge and continue 144 miles to needles

It's a real quandary for me.
As I've noticed I can go very far downhill or on level terrain and can watch the battery tic downward like the gas tank on a V8 pulling a 5th wheel uphill on the upgrades.

Doesn't Tesla factor in elevation changes in the nav calculations?

What % battery is it saying you will have upon arrival?

ABRP has a pretty big buffer and says if you leave with 100% you'll arrive with 15%. I think you're good to go.

But it's definitely worth putting in the destination while you're sitting at home and seeing what it estimates. Bear in mind all these calculations are based on zero wind and driving the speed limit.
