Massive decline in mileage

[Ptibbs]

Are you talking 83 miles straight? Or several short trips?

the 83 in this particular case was over 4 trips

If this was over 4 trips in cold weather, this sounds pretty normal. For Rivians.

I rarely “pre warm” before driving.

Try preconditioning and see if your efficiency improves. Very simple test.

Thank you all for replying. Your collective responses gave me the answer I was looking for - a 30-35% dip over a 6 week period is possible. I never considered that given my conditions haven’t changed that dramatically (the last weeks have been chilly, not polar vortex) but clearly I was wrong. I could look at motor and battery temps and wind direction, etc. But honestly I don’t care enough to go through all that - I just wanted to know if I had a bigger problem.
This comment may piss some of you off, but not being able to confidently go farther than 75 miles in one direction on a charge in winter is massively disappointing. I guess shame on me for not doing more research but that’s pretty weak.

You'll find short trips KILL the efficiency since the vehicle tries to warm everything up (batteries, motors, cabin, etc). This won't impact you as much on a longer drive, but short trips combined with winter temps = a huge hit. Think of it like letting an ICE vehicle run for 25 minutes every time you're about to go somewhere, even if it's 2 miles away. Your MPG would tank just the same

You stated it was over several trips way after most of the replies. You shouldn't have an issue going 75 miles and back if it's in a single trip. Heating is super expensive on battery energy and it's all essentially wasted when you park for 8+ hours unplugged.

My Bolt EV would display just over 100 miles of range under the worst winter conditions, doing my 40 mile round trip commute repeatedly and nothing extra. I still would have been confident of being able to drive 140ish miles in one go because the cold soak period up to afternoon driving is eliminated.

So you can’t go over 75 miles on an 80% charge? I dont think that’s true.

In one direction and have the confidence I can get home without charging (150 miles total). I’ll have to test it but I think it’s close to true.

Probably not true.

To the OP, what height are you usually driving at? We originally were driving primarily in All-Purpose - Standard height, and we found that our efficiency/range increased materially when we changed to either All Purpose - Auto our All-Pupose - Low (Auto keeps the height at Standard for city driving but decreases it to Low at highway speeds).

doesnt piss me off but you should definitely precondition and drive in conserve mode when it’s cold.

Bad short trip EV range is well known to EV buyers. Rivian is both bad and better than some others, because of a very large battery pack and lack of heat pump. Heat pumps are not efficient at very low temps.

I did not know how bad it was before buying though. Multi day range is pretty bad, if I don't charge daily. However, I could get 240 - 250 miles of range even in the worst conditions I could throw at the car , if its a single trip. This is with some small mods that affect aero, 72 degree heat, 75 mph highway speeds, mountains, 1100 ft elevation gain and AP mode(essentially using it like my ICE car).

To your point, the more you drive EV's the more you learn the nuances of battery ranges. I've found my Rivian to be pretty similar to Model S and Leaf in how it handles certain conditions that negatively impact range. One thing for sure is that multiple trips per day really impact range negativly especially in colder weather

Agree. 2 hour breaks only lose small amount of range, may be 20 miles or so. Longer breaks are likely worse.

1st time posting, hoping to get some perspective from other owners. For the last six weeks, I’ve noticed a degradation in mileage. In my current trip, I started at an 80% change, I’ve gone 83 miles, and I’m down to 102 miles of range, all in all purpose mode. At this rate, I will likely get approx 150 miles on an 80% charge. That is atrocious. Prior to this degradation I was getting close to the posted amount of 230 to 235 miles on an 80% charge. Anyone else experience something similar? I live in Massachusetts, but our weather hasn’t been that cold this winter and I took delivery last March in similar conditions and didn’t experience such poor performance in mileage.

The things that reduce your range are speed, resistance (wind), altitude gain, HVAC (particularly heat) use, driving characteristics (lead foot) and weather (primarily temp). I’m also in MA and although the temps of been swinging pretty wildly, it’s enough for the expected (if you did any EV research before buying) 30% or so reduction. Expect worse as it gets colder soon. Also, keep in mind that “miles remaining” are merely a generated estimate based on past driving characteristics are is not necessarily an accurate statement of “state of charge”
