? Official EPA Range and MPGe Numbers for R1T & R1S

[Rod]

The 30 mile hit on 20’s kinda hurts.

Also, do we know if this 314 is based on the truck being AWD or are they using the newly discovered 2WD conserve power mode?

My exact question...

Same! That drastic of a dip to the 20's definitely has me rethinking things.

Not sure why they hyped them up so much at their one event if they knew they would be this low?
Hoping to see some user reviews with real world numbers before having to make the final decision.

I mean, hell, I was still completely undecided even before this! I do still like the 21's, think it gives the vehicle a "cleaner" look, and should be good enough for at least light off-roading, which is mostly what I'll be doing in my neck of the woods. But those aggressive 20's are practically the same as a pair of hitch nuts.

If it is EPA results, can you explain how Tesla could inflate those number? TIA
Maybe they are altering their software/battery available for the tests?

lots of posts on this, but Tesla does a 5 cycle test with the EPA that (in theory) should be more accurate. Because the EPA is a mixed cycle (even their highway test), it doesn't equate to going say... 70mph constantly. So Tesla's are known not to high their rated "range" on the highway. Other manufacturers use a less expensive and accurate test that has a fudge factor applied to it, and then they can also choose to de-rate the range. FOr example, Ford lowered the range from what the EPA would say on the Mach e. The Taycan is famous for this. EPA range of like 207 miles or something, but people routinely get 270 miles on the highwayl.

You won't believe this, but I got a straight answer out of CS. Looks like some handcuffs are off them! Sweeeeeet. More details on those other options in the near future too.

That's actually really welcome news - I mean I'd go 2wd to eke out some extra miles if need be, so it's really good to hear that the testing was on quad motors.

Edit: good call on the potential 2wd + 20s theory for the MT review. Hey, if that's what it takes to get us to the magical 300 mile mark, I think that's totally fair. And if range is really super-important to you, then max out with 2wd on the 21s!

Quote from Rivian's website: "our battery system was built to explore, delivering an EPA estimated 316 miles of range when paired with 21" wheels. For 20" wheels, our estimates show a range reduction of 10-15%, with a 5-10% reduction for 22" wheels."

So just so I’m clear. That’s only 268 miles on range on a fully charged battery using the off road 20’’ tires? Is that correct?

and only 241 miles of range charged at 90%?


is this correct?

 

[TessP100D]

Yeah - This pretty much firms up my resolve to wait for the larger pack for the R1S... Whatever that ends up being.... If I go conservative and say a loss of 15% that's 268.6 miles..... and that's not counting battery degradation nor straight highway miles.... I could see a full charge on the Large Pack R1S netting around 200-210 actual highway miles... (barely)
*Edit - On the 20's that is... but I always intended on getting the 20's.

I think your right too.

No.

Roughly speaking 268 to 280 miles on the 20s fully charged, not accounting for dropping to 2WD or other conservation approaches.

We also don't know how that compares to real world highway range. For reasons we've all discussed many many times.

 

[TessP100D]

Honestly I was hoping this is a very conservative number that real life driving will produce way better results. I can see if that is the case but with out real world testing it is a hit or miss when it comes to all these factors.

My experience is real world driving is way less than the rated range.

 

[Zybane]

Yikes, 10-15% loss of range on the 20" wheels. That means on a cold day we could be talking under 200 miles real range highway.

You got me!?

And I'm configured back to the 22's. These are EPA numbers, so should be in line with other manufactures, Tesla included. The EPA rules are what they are as others have argued ad nauseam.

Ok. Thanks.

I swapped back to the 20s for now. I'm still a bit disappointed they couldn't get higher eMPG. I just look at the Tesla Model X with 100 KW battery pack and 105 eMPG vs the R1S with 135 KW battery pack and 70 eMPG. I get the aerodynamics, weight, etc. I was just expecting more power train efficiency is all. Tesla still dominates that area and maybe Rivian can catch up in time.

Honest question, if tires can cause 15% mileage loss, towing 11,000 lbs has to be greater than 50% loss right?
