    Beta test Rivian Watch App coming: WatchMyRivian

    Gen1 does not have UWB (ultra-wideband) and as such will likely never get watch as key. Similarly, they clearly determined at some point that the hardware in Gen1 was incapable of a ton of functionality they claimed it could do as far as ADAS is concerned and I wouldn't expect any significant...

    Car and Driver R1T 40K mile Test

    Cooling is definitely the big one. For the pack voltage, we're already pulling 500A to get 200-220 kW. Rivian only uses a single cooling plate in the middle of a double-stack of 2170 cells which leads to a temperature gradient large enough they have to slow down charging prematurely. If they...

    Update 2025.06 is out!

    I was surprised how long it took to apply. I added a 20" AT w/aftermarket snow tires. It's really weird that it doesn't ask/specify the tire size when selecting the aftermarket option, but I'm assuming it must've still used the stock 275/65R20 size as my estimated mileage did not change. I'll...

    Car and Driver R1T 40K mile Test

    Didn't I hear them claim 59 minutes 10-80% though...while sitting on a ChargePoint unit they wouldn't get more than 62 kW from? I have a charge session I documented in extreme detail showing 10-80% in 42 minutes (it was actually 9-80% in 43 min) and holding over 200 kW for 15 minutes (adding 51...

    Radar Detector hard wire, who has done it?

    I've been running one since 2012 when I got my first sporty car, Subaru STi. When I got the Rivian there was no question about running one since it accelerates so damn fast. Like mirrors on a motorcycle, it can't tell you what you can't see (they have to be running radar continuously, not over...

    Towing + Efficiency: Please post your experience!

    Nice! Evora 400/GT was high on my list when I finally settled on the Alfa 4C instead. Any issues with the Futura and mid-engine car getting good balance / tongue weight with the wheels on the trailer being so far forward? I'm in the market for a trailer this year. Same question as...

    Tesla drivers named worst drivers on Georgia roads

    Things like this are why training your ADAS on owner driving characteristics is bad. You'll inevitably introduce some really, really bad data into the training data that will cause unpredictable results during use...like the Teslas that would clip curbs using FSD. So many Tesla owners curb...

    Beta test Rivian Watch App coming: WatchMyRivian

    FWIW, I had a Rivian tech tell me that they've seen folks have issues with unofficial watch apps that try to integrate with the key system to the point that the owner had issues accessing their vehicle and couldn't remove the key causing the issues. Because an unofficial key was used the...

    G1 QUAD Overheating Motors

    Are you on 2024.51.2? I had a lot of odd infotainment restarts on 2024.47.1, but haven't had one since 2024.51.2 came out.

    It was definitely a choice. 🤣

    2025.06 Update Release Notes

    Yup. My MINI Cooper SE had charge for departure and used the same schedule for the HVAC just by toggling a check box, it was glorious and required no thinking. If you went two days without a drive cycle it would disable the schedule. With my Rivian, I always use one of the trip meters as a...

    Starlink Mini

    Higher latency aside, 100 Mbps is still faster than I've ever seen the LTE hotspot in my truck. I think the most I've seen is maybe 30 Mbps and I've just assumed this is a bandwidth cap on the type of commercial account Rivian/AT&T are using. In the same location, my phone will routinely see...

    G1 QUAD Overheating Motors

    That's orange, not red. The Gen1 quads do this when preconditioning the battery for fast charging...totally normal. Your battery was at 65F and it wants to be mid-70s to low 80s for best charging performance.

    Toyo Open Country A/T III EV Tires (LT275/65R20) - Fantastic (Review & Efficiency Stats)

    IIRC, it's the 275/60R20 that's the same 33" diameter as the original 21s and 22s. The 275/65R20 is a 34" diameter tire as the OE 20s came with.

    VW ID.Every1 = first product of the Rivian-Volkswagen JV

    Honestly, after dealing with public charging while staying with family for nearly two weeks...EVs are just not for anyone that doesn't have charging at home right now. Much of the benefit is always waking up with a "full tank" and just not worrying about it. Can it be done with a longer range...

    VW ID.Every1 = first product of the Rivian-Volkswagen JV

    My MINI had all of 110 miles of stated range. One of the most entertaining cars I've owned...fantastic "city car". I was actually behind one on the drive into work this morning too.

    Colorado Checking In

    I look forward to your review of the LT3. I've been on the Blizzak LT for nearly two seasons now and they work well, but I've been curious about the Nokians.

    Reminder: Rivian Promised Level 3 "Eyes Off the Road" Autonomy on Gen 1

    Yes they did...and it'll literally never happen. The existing hardware can't even deal with Lane Keep Assist properly and keeps trying to jerk the wheel out of your hands when one lane splits into two or massively phantom braking because people are in a turn lane you're about to drive past...

    All OEM wheels now available as spare tires + new tire lift harness in Gear Shop

    Yeah, closer to $350 would be more reasonable for a 78" x 6.5 ft awning. The no support poles needed part is nice, but only 25 mph wind rating and not really worth nearly $1k more than others.

    ‘Big Boost Coming,’ Says Investor About Rivian Stock

    And then some of us bought in early and got screwed. You can only keep buying down your basis so much. Oh well, I still believe in the company and its products long term, but it keeps making little sense that every bit of good news the market turns into bad news somehow. Maybe R2 launch will...
