? Official EPA Range and MPGe Numbers for R1T & R1S

[Eager2own]

Wait… 90-95%? Would t that be 85%-90%?

No. As I said , 90-95 of original target range (of 300 miles).

I thought 314 miles was great, until I saw the "10-15% reduction for the 20" all-terrains". That definitely makes me think about my choice to have those on my config.

A few questions/thoughts remain though for me:

1. How does the "Conserve" drive mode (which shuts off 2 of the 4 motors) affect things?
2. Do we think 314 is actually an underestimate, similar to Mach-E and Taycan's EPA estimates? Or an overestimate like all of Tesla's EPA estimates? We'll need people to run road trip tests to find out
3. I'm interested to see if they can improve this over time with software updates. My guess is yes, definitely.
4. I noticed they said specifically "Launch Edition" in their post. Wonder why? Would non-LE be expected to have different range? I wouldn't think there'd be any difference, but maybe they're thinking they're going to get rated again by the EPA for non-LE models based on any efficiency improvements they're planning.

Regardless, I just want over 300 miles usable real-world so I'm happy I'm going for the Max Pack.

Yeah that top line really hurt me in the feelz
I wonder if they had *different* 20" rims that the range could be extended? Lighter materials for the rim such as magnesium or titanium (I've used both before, they're great but super expensive compared to alloys or steelies). Or perhaps a different design that creates less turbulence (I mean you could test it by covering the entire rim with a flat plastic disc but that would look incredibly lame)
Its great that the EPA actually rated the car at 14mph above what Rivian was advertising. That shows their estimates are conservative and more importantly, the company is trustworthy.

But damn, I did want those 20" rims... I may just buy with the 21's and then buy a set of off road rims locally and put them on only when I want to offroad...

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

My experience mostly differs, but so much of it is driving style and location. I'm on the West Coast where I don't run heat very often in the car and I live in a town where I maintain under 50mph most of the time. My 2014 P85 has a lifetime efficiency of 292Wh/mi, which is better than rated. My 2016 X90D had a lifetime non-towing efficiency of about 310Wh/mi, which was also better than rated. My current 2020 LR++ X is a bit more confusing because I cannot reconcile the trip computer with the mileage driven. It reports a lower number but I do not believe I am achieving that in reality. I think the LR++ range is stretching the truth a bit, honestly.

I won't be surprised if I do better than the rated on my R1T when it's in-town and untethered. Towing will be a different story entirely!

I was just told by Tesla that city stop and go uses way more energy than a constant freeway driving. I have found this to be true as well.

It may be the case for real-world driving, but that's not how the EPA test is set up. Go to the website and look down below where there is an option to 'personalize' the estimate. If you change it to say 100% city driving, the EPA range goes up: https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=44461&id=44462

Does target range still matter? Or will we just move on to the EPA rated range, a d adjust for real world?

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.

https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=44462&id=44461&id=43403&id=43406

Aerodynamics and weight are by far and away the two biggest factors to eMPG.

The official EPA range values for Launch Edition vehicles are in:

R1T Large Pack: 314 miles
R1S Large Pack: 316 miles

Electric Driving Range
City Range (miles)	Hwy Range (miles)	Comb Range as shown on FE Label (miles)
331.4	296.4	316
331.4	296.4	316
331.8	292.9	314
331.8	292.9	314

162 kW AC 3-Phase

162 kW AC 3-Phase

Thanks again for the awesome info!

K, I think I got it...after four pages of replies were added in the time I started reading the first page lol?‍.

All out of jokes for today.

& Happy Labor Day weekend.

When I woke up this morning I was interested in the Rivian with an estimated target range of 300 and knowing that I’d get something less than that with ATs (I was assuming 10% or more hit).
Learning that Rivian has hit (and exceeded the target) and that the resulting numbers for the AT are therefore within 5 to 10% of the 300 was great news for me, and I’m still interested in the Rivian.
So, yes, EPA numbers are what matters, but the fact that they exceed my target and expectations is good news. Why would I bitch about Rivian doing better than target?

I want to caution about the enthusiasm of unlocking “additional miles” by using 2WD on highway. The EPA test states “part time 4WD”, which leads me to believe that part of the test were using 2WD (likely the highway portion). I know that someone has asked CS and the response was that the Rivian Truck/SUV were tested using 4WD. I hope that response is accurate but a lot of times, CS reps might not have the factual info or could be mistaken.

Also, for people wondering if the ”real Miles” could be better. The likelihood is low because the EPA tests at highway portion are at lower speed relative to actual speed that most people drive at highway. We are all hyper-focused on the range because of the road trips and those road trips are pretty much mostly highway driving.

314! Rivian really did it and delivered on the 300+!


And that MPGE looks pretty good to me:

 

[RWerksman]

While this is great information, I don't think we're going to know how this actually stacks up until someone independently does a 70mph test, like Inside EVs.

Also, FWIW, the Mach E AWD / RWD had a range differential of 2 miles when tested at 70mph. Anyone who is hoping for magic by moving to 2wd only here probably isn't going to find it.

People don't seem to get there a maximum possible effiency to electric drivetrain, you can't get above a certain limit even if you put 100 billion dollars onto the problem. So stop saying you hope for better drivetrain in the future, hope for bigger batteries and solid state.

 

[TessP100D]

I don’t think that is right, considering regenerative braking. The effect of drag on efficiency increases by velocity squared. From most to least efficient it would be city driving without any stopping, city driving with stop and go, then highway constant speed.

edit: if that were true why would Tesla have larger EPA ranges for city compared to highway?

Regen braking doesn’t add any range to city driving. None

The range on the 20s is disappointing. Remember real world numbers will likely be lower than lest say 15% reduction of 268 miles. I wonder though if that was with 4 wheel drive mode and 2 wheel drive mode might get that range back. Anyone know if Rivian has said how much power/range the 2 wheel drive mode saves?
