About 35 minutes 10-80 on software 2025.18. Almost 10 minute improvement over the previous times. Pretty substantial improvement in fast charging times.

Why would rivian choose to run the smaller batteries harder with higher C rates though?

You’re right. I missed the fact that they all peak at 215kw now. You’d think the bigger battery should have a higher peak. Interesting.

10-80 time is supposed normalize for different size batteries. I’m betting OOS did their test on a charger that is >250kw so the constraint would be the battery not the charger. My guess is that large and standard likely have larger hidden buffers and that is why they charge in shorter times. Eg...

Looks like they got within three minutes of what I was hoping for. Roughly seven minute improvement for 10-80% is not bad. Still not understanding why smaller packs have faster 10-80 though.

Since mine is a gen1 max pack, 2025.18 is the first software update that is supposed to address the DC fast charging issues. I believe gen2 max pack had some updates earlier in 2025 that increased their charging speeds already.

You're right ultimately we care about miles added per time duration but there are so many versions of the vehicles (performance, dual, quad, tri, wheel/tires) and 10-80% is a direct comparison of just battery performance without looking at configuration etc. OOS chart below shows that in a 40...

End of the day charge times is what we care about when it comes to charging speeds.

Comparing percentages is one of the more direct ways to compare charging speed. This helps normalize the battery sizes.

Interesting video comparing Tesla supercharger to EA. Looks like about 45 minutes roughly for 10-80%. Hoping the software update can cut 10 minutes off the 10-80% down to 35 minutes. 45 minutes is slower than the cars listed below according to Google AI.

Hopefully OOS redoes their test after this update. Curious how much an improvement it is.

Seems like Rivian heard us. https://riviantrackr.com/news/whats-coming-in-rivian-update-2025-18/

Right on. Vampire losses are a whole other ball of wax. Was just trying to get driving efficiency data here.

Yeah a screen shot of the trip meter for the super high or super lower numbers would be very helpful.

Yeah I realize many variables will be at play and I’ve seen the other threads. I figure having a poll makes the data easier to see even if it isn’t perfect.

Curious what people are getting for efficiency long term. I’m getting about 2.62. I have a dual max r1t with 21” wheels.

Providing current mileage is probably an important aspect. I haven't lost any range on my ‘23 dual motor max as well. Only have about 6k miles though.

Thanks for posting. Bummer that it cost $30/year. Was hoping for a no cost option or at least non reoccurring cost.
