So… it seems like the big advantages (plus combining one of these with a vehicle with a charge port in front):
1. Great aerodynamics
2. Regen on hills means more efficiency on hilly roads
3. Can use the trailer battery to extend range
4. Being able to pull in and plug in tow vehicle, disconnect...
A dual motor with open diffs or a quad motor… redneck mechanic here thinks the tools are built into the vehicle with the right software. (Just kidding)
I wonder if the software limits the following distance if winter tires are selected since braking distances increase in low friction conditions. (SoCal owner, so no winter tire swap here) I’d try to choose a non winter tire on the menu (in non slippery conditions) and see if the following...
IMHO the optimized option for Cd/headroom is currently what the R1 series has. Steel roofs usually lose quite a bit of headroom to headliner thickness so one has to have a higher roof, worse Cd, larger frontal area, etc. to have the same headroom.
Glass roofs are very efficient for manufacturers. Making only a glass roof on a model of a vehicle allows a less tall vehicle for the same headroom = less weight (probably), better aerodynamics, lower Cg (probably) plus less painted surface for finish flaws. Maybe someday an engineering YouTuber...
After update 2025.26 our dual motor is back to the way it was for the first 20,000 miles. So glad, it is much better now. For reference I had it in for service for something else and they recalibrated it a month ago with zero improvement. Edit: Gen 1
I think most ECOflow in pass through mode will allow 1800w even if you set a lower charging limit. So, you may have to charge up the battery to a higher state of charge than your “backup reserve” limit, then run the high draw items and then move your “backup reserve” limit higher to charge up...
Also good to check your battery temp on a hot day after fast charging. We pulled out of the fast charging location and lost 99% of normal available power. Rolled to a stop then checked battery temp which was red. The available power bar came up quickly and we were on our way one minute later...
I have closed my Rivian app but my phone still locks/unlocks my pickup. I have to power my phone off and on to get back to “normal.” It seems to be a standard Apple procedure that I do to my Apple devices at least once a month.
I would recommend charging at as many amps as you can for shorter periods. At 1.92kW a high percentage of your energy is going to the computers to keep everything awake.
I visited the Rivian chargers in Sacramento. The prices were $0.39 per kWh for DCFC and $0.18 per kWh for the Level 2 chargers. The level 2 rate is less than I pay at home at off peak (my lowest rate) and the DCFC is between off and on peak. Seems like a great price to me.
Did a convoy with two Gen 1’s. An R1S dual max on 21” OEM’s followed by R1T Quad large on 20” OEM set to follow setting 2 on I-5 in CA. The S left the DCFC at 75% and the T left with 77%. Drove the speed limit to plus 5. The R1T battery was 10°F warmer than the S. R1S arrived at 20% and the...
I hadn’t heard of this until our Hyundai Ioniq 6. It turns on an orange light on top of the dash to let us know the drying mode is active. It would be great if Rivian added something like that but a drying cycle would be nice.
It is a great step to load/unload kayaks and other things on the crossbars. When the T was in for service we used our S for the kayaks. Not only did we have to bing a ladder, we also had to bring bins for the wet stuff.
It could make sense if one were traversing a long distance at slow speed with access to the next charging infrastructure beyond the range you need. The shade would be nice!
I wouldn’t attach one to my Rivian since the miles lost due to drag would probably be higher than miles added. Plus the cost of a solar generator, mounting setup and wiring. The solar generator would need to be in the open bed of the pickup due to its cooling needs. I would also secure the...
