Did Rivian Drop Tri Motor Range?

[CarlM408]

I don't expect that is correct. If it was Rivian wouldn't advertised 'conserve' range in their configurator.

Well...hunh. You sir have a point, yet that seems to be in contrast to everything I've heard 'verbally' about the new drivetrains.

Interesting. So apparently Tri and Quad Gen 2 will have conserve mode like Gen 1 quad?

Hey anybody who has a pre-order, or who looks at the Rivian website daily notice how tri motor has gone down from 380 to 371 miles?

I'll be honest less and less do I really believe these numbers and all I'm hoping for is 50 to 60 miles above what I'm getting in my quad motor.

Yep, just checked my reservation in the Rivian app and the range on it was adjusted and that includes the 22" range wheels..

2 wheel drive conserve mode, the heat and weight of the vehicle goes through the tires. I drive 30k highway miles a year and never using conserve mode has given me an additional 7k miles tire life.

The option I suggested selected once on highway would be negligible to tire wear vs All Purpose. Now driving in conserve around town with the torque only on front wheels and also in auto for low setting does eat them like candy.

Yes, EVs go through tires faster due to weight like an F350 so we agree there.

Did they just drop it again? Between charging issues and low efficiency, I’m starting to wonder if something is up with our truck.

I don't think so. Those numbers on that screen are "based on your driving history," which explains why it's lower.

While my driving has been closer to hypermiling than drag racing, with plenty of time in the 3-4mi/kwh range, I'm still not hitting that 370mi in the range estimate I suspect it's as optimistic a figure as Tesla shoots for.

If you have a perfectly flat and prepped road, no wind, 75% ambient temps, no passengers or cargo, no climate control or lights or anything else on, and stick to exactly the rated speed, I'm sure you could hit the estimates or even exceed them. But nobody really drives in those conditions.

note the video shows me resetting it I’m well aware of the epa games but this is now showing a lower range than our old gen1’s (with smaller batteries) at its default. My m/kwh also show lower efficiency. The one thing I cared about moving from a gen1 quad to gen2 tri max pack was increased range - so far I’ve seen the inverse of that.

Yeah, I saw that, but I just don't know what that button does. None of your numbers change, which suggests to me its actual function is a bit of a black box. Does it instantly reset estimates to full EPA? You seem to (reasonably) think so, but maybe you need to start driving it a few minutes before it does something. Or maybe it only resets a "driving history" multiplier and starts applying that to your cumulative history? Honestly, I dunno

The estimates are based around low speed driving. I'm sure any Rivian can hit its advertised range at 40-50mph. But they aren't highway figures.

I am sure the Tri Max has better range than the quad. Lower numbers could be explained by colder weather or just Rivian changing the formula for the estimates. Also, maybe the current tires are less efficient?

And these are just estimates, not magic numbers. They can't actually know how far you will go without even knowing what speed or conditions you'll be driving in.

That said, I've been one of those saying from the beginning that Gen 2 range estimates are overoptimistic compared to Gen 1. The Tri Max has 10kWh more usable, that's 20-25 miles of range typically. Weight and efficiency improvements might bump that up, but only slightly. The new wheel+tire combos might also be slightly more efficient, but again probably not much.

I would think those numbers, to be advertised, MUST be based on EPA figures, or at least estimates of the EPA figures, which would included mixed city and highway driving. I don't know what the specific speeds are for highway driving for the EPA test, but I'm sure there are tons of resources out there that publicly document it.

Yep, the EPA tests are notoriously based on much lower speeds than a normal highway which is what I meant. https://www.fueleconomy.gov/feg/fe_test_schedules.shtml
