Nice! Been meaning to do that whenever my R1S is finally fixed.

What drive mode did you use on the way down? Off-Road all terrain or did you use rock crawl?

Was the regen enough to prevent break overheating? That was my only concern since it’s so steep.

I used “All Purpose” the whole way. Anything else would be overkill.

I never touched the breaks on the way down until Saddle Road. I gained 30 miles of range over the 70 mile (and return to sea level) trip back to Kona.

The R1T did an awesome job both climbing and descending. It was so much better than my Grand Cherokee.

I took mine up the Lanai Hale, only about 3,400 ft, and didn’t have to use the brakes all the way down. All purpose mode as well. Handled way better than my p38 Range Rover, and much quieter.

Note, by default Rivian will now use real brakes even in regen mode, if the regen is overloaded.

Very nice. Especially the image of you taking the image on the center screen. Nice detail to the composition!

Is this a new feature that means that you can still control your Rivian with one-pedal driving even after the regen overload warning? I get the warning quite frequently in the hilly terrain in northeastern PA and so far at least, I need to use the brakes to slow my R1T after the warning pops up.

I don't remember seeing any warnings about region overload on the way down. Here's a short video from the front drive cam as we started down.

You were bumping up against the FAA rules concerning oxygen requirements at 13,751 feet MSL.

I can say with confidence and first-hand experience that riding your gravel bike up that mountain is the hardest thing I've ever nearly done (and failed at). Crapped out at just under 12k' and came back down.

Next time, I'll drive. lol

How much battery did you use from Kona to the summit?

Amazing photo - Thank you! And the fish-eye view from the front camera really reinforces the "top of the world" feeling. If someone dropped a smoke bomb in that road crack at the end of your video I bet the mountain would clear out in a hurry!

Kona to Mauna Kea was -171 miles of range.
Mauna Kea to Kona was +32 miles of range.
Total would be 139 miles of range for the 136 mile round trip. Crazy.
I don’t remember the battery percentages.

…and making it to 12K on a bike is incredible!

Well you definitely feel the altitude. If you’re in an ICE car, you’ve got to unscrew the gas cap or you get a bunch sensor warnings.

When my R1S is repaired, maybe we can take the R1 Mauna Kea Access road one day:

We should also re-create this photo of my Cherokee with our Rivians. It's stunning up there:
