? Official EPA Range and MPGe Numbers for R1T & R1S

[TessP100D]

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.

Great job.

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.

Looks like my point 3 has already been answered:

I'm going to assume this is w/out the off-road upgrade package (tow hooks and additional reinforced underbody shielding)

Yep. Clicking on the "Estimated Range" link gives you this message:


The official EPA estimate for the Large pack battery is 314 miles for R1T and 316 miles for R1S. The range shown for the R1T Max pack battery is an estimate.

Your range will change depending on selections such as the Off-Road Upgrade, wheels and accessories. Other factors that can affect range include driving surfaces, weather conditions, cargo and towing.

This was exactly what I was expecting, so I don’t see why some people seem so surprised. This is a great range for the wheel/tire combinations. I’m sticking with my 20 inch wheels with the ATs, and if I ever need more range for some reason, that sounds like two wheel mode will help with some range. I bet you with software updates and calibrations will have increased range over the life of the car as well.

I could always buy a second set of tires with less aggressive treads on them, it might even beat the 21 or 22 inch ones

Hopefully software updates/increasing the range will keep up with the battery degradation losses.

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?

Generally when the EPA tests a vehicle, they test the standard mode, which in the R1T's case would be 4 motor drive. I bet you'll see a lot more range from 2WD.

 

[TessP100D]

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.

That right.

 

[Temerarius]

I'm not terribly shocked by either stats (eMPG or the impact of rims).

They are, at the end of the day, "traditional" in design, and they will have a slightly better drag coefficient than a barn door flying down the highway.

I'm not thrilled by the numbers and am doing the "Hmmmm.... 20 or 21's?" dance again as well. The saving grace is I went with the Max pack, so I'm still well above that 350 mile with the AT's.

I'd be curious what the impact of 2H does to the numbers.

I get that and agree. It’s just i see a lot of buyers here who talk about off roading. Max pack required in my opinion.

I know Rivian is marketing to off-road enthusiasts as that sells. I've looked at the R1T from the beginning when I first saw it as a sports truck with 4 motors, kinetic suspension, many of their team are from McLaren. Remember, RJ loves Porsche's since his youth. RJ has also stated he was driving a Porsche Cayenne for a long time as a comparison during R1T development. I started thinking about the 20" wheels after the reviews from Duck and others, but I think the 22's will be great on road. I'm in NC, so no real fear of snow, just need to be good in the rain. Just my opinion.

 

[lg3103]

What will be the extra hit for the off-road package?!?

 

[Bumble1978]

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!

Max Pack + 2wd Mode + 21's = Road Trip ?

I get that and agree. It’s just i see a lot of buyers here who talk about off roading. Max pack required in my opinion.

I forgot...I've been Max pack since the beginning. Remember, Max use to be Large, and Large was Middle. It's all marketing.

 

[TessP100D]

Ok. Let’s rolling out and get them into the hands of the first lucky buyers.

 

[RunnerPaul]

I chose the 20" wheels, so now it is going to be interesting to if I can get above the 300 mile range while using the 2 wheel drive mode.
It is a 116 mile round trip If I drive to the office so still good enough for my needs.
Hopefully there will be OTA updates that will gradually improve the range.

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.

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?

 

[mindstormsguy]

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?
