The 2025 Rivian R1S Large pack is...uh...not so Large (or efficient)

[Supratachophobia]

2.38 mi/kWh

Isn't that pretty much par for the course in the R1S?

I got 2.35 on a 267 mile round-trip in the same day. So yeah pretty normal.

I'd take that all day long with my LE R1T

Hey, I got 2.4 for many miles on the interstate in my LE R1T w/20-ATs!

Of course, traffic was terrible, so my average speed was about 35 MPH.

2.38 is pretty decent for a vehicle of this size.

It's amazingly efficient when you compare it to my Wrangler 4xe that weighs 5,100lbs and goes only 23 miles on a 15kWh (usable) battery for a "worst in class" efficiency of 1.5mi/kWh

Do you have a full electric drive-train or is the engine connected to the wheels?

My dual Motor was at 2.52 before winter at 10,000 miles.

Now down to 2.10 lifetime..... winter + 1000 miles of towing took its toll.

Think of a standard ICE vehicle arrangement ICE connected to an 8-speed transmission connected to a rear differential, then add an electric motor inside the 8-speed transmission. That's how Jeep does it in the Wrangler 4xe. So it's a completely conventional drive train except for the electric motor inside the regular 8-speed transmission.

The answer is the climate control. I would preheat my vehicle in those temps and drive to the gym with only heated seats and steering wheel on and get close to 3.5 miles/kwh

Climate control will kill it, especially if it’s blowing heat. I guarantee you if you had climate off you’d be getting 3+ mi/kwh assuming no strong headwinds on mostly level ground.

At least after things warmed up. My truck sucks for the first mile when cold. I typically go up a hill for the first mile when I leave my house and it isn't huge. Maybe up 100' or so.

When cold in the winter, I am at 1.0 mpk. Now that it is warmer, I am 1.5-1.6 mpk when I start out. If I come back home and leave again with things up to temp, I am about 2.3-2.5. This is an area with a max speed of 30 mph. My Teslas are affected but nearly as bad as my Rivian as a percentage.

I can get 3 mi/kwh (or better) in my Cybertruck AWD in the same conditions.

Were you running the heat in the CT? I am getting 3-3.5 mi/kwh in the same conditions you are. Not running hvac.

What's the adjusted efficiency to account for the stainless steel panels remaining attached to the vehicle for the entire trip?

On my 2024 R1T, Dual Motor, Standard+ Battery size, I see in the high 2's and low 3's when I drive to work and back. 35 miles each way, maybe 50-70mph, depending on traffic. But I am constantly in around 2.7kWh to 3.4kWh.
But in our 2023 Quad R1S, the same commute is in the high 1's..

Don't recall, both vehicles were at 72 auto and low fan speed. I rarely change it.

Well that's a big difference....running resistance heat will absolutely drain at least 1/2 a mile per kwh. It's one of the single biggest consumers of energy outside of driving. There's your answer. I just drove my R1T dual motor today and was getting 3-3.5 mi/kwh driving around town with no HVAC on.

Not really. I pre-conditioned the R1S for 30 minutes before departure and it was low to mid 50's outside so it wouldn't take much energy to maintain temp with the sun load during the day.
