And this was already the case with Gen 2 R1 (advertise 410, get ~350 at 70mph). R2 is even worse but Rivian was already marketing based on unrealistic EPA numbers.

First tell us what happened when you tried with the Grenadier.

Well my point is that if you need 300+ miles of highway range, you might have to go up to R1S anyway. Yeah, unfortunately as soon as the battery pack was revealed to be 2/3 the size of your Quad, there was no chance the range would be competitive. Rivian was not very open about this. Good news...

I hope so but my bet would be they don’t because of fear of taking away R1S sales.

Cool. I'm big on the "free market". People should be free to buy gas vehicles in 2026 if they want. But the externalities of pollution and climate change should be priced in. Otherwise it's not really a free market, it's off loading costs to others and our children instead of paying ourselves...

This is my rule of thumb for R1 too but maybe it will be slightly better for R2. Hm, maybe not. My math says that the physics required to lift R2 to 7000' above sea level is very roughly 14 kWh, which is 16% of the battery pack. So the absolute best case scenario here is like doing a flat 200...

From everything I have read and seen over the last 4 years, data shows almost zero difference between the dual, tri, and quad motor highway efficiency if the tires are the same and especially if conserve mode is used. Powertrain loss is a small contributor to efficiency at highway speeds, it's...

Can you tell us exactly what speeds you were driving at? Sure. In those conditions my Gen 1 Quad gets 330+ miles despite only EPA rated for 275. But we need a bit more info about what these test conditions actually were

That test was at 5000 ft elevation, so you'd expect a significant improvement due to thinner air, I'm not an expert but maybe 5%.

About what I expected out of R2. The R1S numbers above are from a different test, so not directly comparable. R2 would do better than this head to head.

Thanks for the correction. I stopped watching his videos a while ago so that checks out

All you range nerds don’t forget that OOS tests at altitude and results are slightly favorable due to think air, maybe 5% at 70mph I don’t know.

I don't know if anyone makes aftermarket wheels for the R2 but I'd be confident some will come out by ski season. I run aftermarket wheels and Nokian Hakkas on my R1. For those suggesting a true AT tire like KO3 or Toyo, that is not a good replacement for a true winter tire as the first post...

I have the MSW Type 52 for winter tires but those look even more affordable.

Very fair, but I would like to see the EPA add a 75mph highway test (without getting rid of other tests).
