2023 Rivian EPA Numbers published on official website

[Dark-Fx]

I know Rivian has shown these new numbers in the configurator for a bit now, but they just started showing up on the EPA website late yesterday for the 2023 model year.

It's helpful that they have posted official numbers for each wheel size. The previous method of saying "a reduction of XX miles for 20" wheels and XX for 22" wheels" was confusing to some. Maybe that is an indictment on our education system though....

I am still confused why the 21 inch wheels have such a large difference between the R1S and R1T. The 20 and 22 numbers are the same between the 2 vehicles.

I don't see testing documents published yet but I'll share them when I do.

That's interesting. I assume both have aero covers, right?

Ugg... I why couldn't they have made the A/S aero wheels on a more common wheel and tire size?!

I think they should remove aero covers and make them optional in the gear shop. Seems like the first thing everyone is doing is taking them off.

I agree. I'll be removing mine and put them back on for road trips only.

Do you all think there is an actual change, or just a change to the testing? I understand the manufacturer has some flexibility with the published numbers… I haven’t seen anything that makes me think this is more than Rivian making their range values a bit less conservative (which they feel like they have been).

I imagine there might have been a small amount of efficiency to be gained with better HVAC controls, but I haven't read anything about an improvement to the motor inverter, and that's typically one of the big ones that other companies use to bump range up with.

I was seeing 330 miles on a charge on 21" wheels. So I'm guessing they changed the testing methodology. I would love to be wrong though!

I guess I am getting confused on all of the range discussion.

Does this:

A. imply that at some point model 2023 models will start delivering with a higher range
B. imply a software update is going to increase range for all R1 models (better efficiency, access to more pack capacity, etc)

C. Rivian following in Tesla's footsteps and learning how to game the testing better.

I’m guessing they redid the test on the latest software with improved regen and were able to squeak out some additional range as a result. It is also possible based on the reported drive mode improvements that some of the algorithms may have adjusted some of the power consumption curves.

Still waiting for someone that saw regen going down large declines (especially while towing) and cutting out to report if the new changes improve that or not.

I haven't experienced the complete regen fall-off that I had been experiencing in the last update, but that was rare to happen and I'm not in a particularly mountainous area.
