So I was bored after dinner so naturally I wanted to take the R1T for a drive.

So I decided to drive from my home in Sandy, OR (~800 ft above sea level) to Timberline Lodge (~5800 ft above sea level) over a total distance of 35-36 miles. Temperature was low 50s F in Sandy and mid 30s F at Timberline.

I drove with auto climate control on at 69 and heated drivers seat at level 1. 20” AT tires installed.
For the first flatter part of the drive between Sandy.and Rhododendron (and reverse) truck was in conserve in standard ride height
For the steepest part of the climb between Rhododendron and Timberline and back I used all purpose in standard ride height

Leg 1 (to trip) - Started at 66% SOC and arrived at 40% SOC

35.2 miles
1.17 mi/kWh
30 kWh used

leg 2 (return trip) started at 40% SOC (got up to 42% SOC) and arrived home at 37% SOC

35.7 miles
17.87 mi/kWh
2 kWh used

Overall 2.23 mi/kWh

A couple of observations in general I noticed on the trip:

The trip meter doesn’t give correct information when you have gained energy via regen. I watched the trip meter go from 2kWh used to 1kWh used to 0kWh used then back up to 1kWh and 2kWh used. The trip meter didn’t appear to understand that wasn’t consumed but gained energy.

Auto High Beams work pretty well, turn off a bit closer then some other drivers may appreciate. I also blinded someone That passed my on a 4 lane part of the highway. They didn’t turn off until he had completely passed me and the car could see the other cars taillights. I suppose this could be fixed by adding some logic to turn them off when someone drives into your blindspot.

I like how even in climbing and then descending all that way you still net out about 2.2mpk. We’re you driving like a grandma or like some of us might who just got a new fast toy?

For the section of the drive that I was in conserve I would say more like grandma, 10 over posted limit (which means 7-8 over based on GPS) and I used ADAS.
For the section I was climbing, which is a windy highway, I was having more fun :)

I wonder if they forgot to allow it to present a - on the UI, but it calculates it correctly.

Did Driver+ actually work there? I am shocked if so. I drive from Portland to Mt Hood or Portland to Bend regularly. If 26 is mapped for Driver+ it will be a big deal for me.
No, definitely not. By ADAS I meant only adaptive cruise.

So far I have seen the full Driver+ working on the following highways:

84 From Gresham to I5
26 From I5 to out past Hillsboro

Yeah, maybe what I wrote isn’t clear. That is what I think, it was actually -2 kWh over the first 4 miles from Timberline towards Government Camp. So it was telling me I was using 2 mi/kWh but actually I was producing 0.5 kWh/mi

You're going to hurt some heads pulling shenanigans like that dude. Be nice to those who don't appreciate the maths. ?

If I was trying to do that I would have made a post about air resistance vs rolling resistance (weight). I was working out the math last night for funsies :)

Turns out the air resistance is proportional to velocity cubed while rolling resistance (weight) is only proportional to velocity.

I was thinking about it in the context of pulling a trailer.

Now you have me thinking I'm missing something. Velocity squared not cubed right?

Fd = cdĂ—AĂ—v^2. Right?
