Mountain Question

To those of you who regularly drive in the mountains or have on a road trip, how accurate is the MINI app route planning with elevation changes?

I’m heading up the nearest nine thousand foot peak tomorrow morning on an EV group club drive. The MINI route planner says I will have plenty of range, but I’m curious as to the experiences of other SE owners.

Steep up hills will drain the battery very quickly. It's about triple the normal rate when I drive up to the Big Bear area in So Cal. You get a lot back on the way down of course. I find ABRP to be fairly accurate in accounting for inclines.
 
Good suggestion. MINI route planner says I’ll have thirty four % battery when I get back. ABRP says I’ll have twenty %. So, I I’m good either way.

Round trip is one hundred and two miles. I live at twenty four hundred feet, so elevation change is about six thousand six hundred feet.

Assuming you are using summer tires you should be fine. Even using ABRP's estimate of 80% to go 102 miles is an efficiency of 4.41mi/kWh.

After your trip, please give us a report describing your driving style on this trip, the weather conditions you encountered, your lowest battery % during the trip, and your final battery % when you returned home.

Those of us who drive all their miles in town need to hear tales from the more adventurous SE drivers.

Thanks!
 
The base of the mountain is twenty four miles away, all city driving. Up the mountain is twenty six miles.

According to ABRP I should be at thirty five % when I get to the top of Mt. Lemmon. And be at twenty % when I get back home. If that is the case, I will have used sixty five % to get to the mountain top and will use just fifteen % to get back home.

I suspect you'll do better than that, in part due to thinner atmosphere at the higher altitude which should reduce vehicle drag. And unlike ICE vehicles, EVs shouldn't lose efficiency higher up.
 
They are great in the mountains. I never use the planner, I just go and don’t worry. I go from 5,000’ to over 10,000 often. You use more than on flats going up but make up for it on the decent. My best is 142 miles driven with 22% left afterward.
