New R1S Dual Performance Max AT Range issues

[LiamJacobs]

If you haven’t already pair your rivian do to live data with ABRP (there’s threads here on it) after some time it will learn your driving habits and usage. I’ve found the Abrp routes to be significantly different after learning my consumption from the truck. Though ymmv

I have purchased the premium (mid trip) and noticed a big improvement in the calculation.

Have made about 4 road trips out of LA to Bend, Oregon and Lake Tahoe, Mammoth Lakes and Moab, Utah. I take pride in actually INCREASING the estimated milage at destination and stops in between. 90% of the time I am able to do that by never going over 70mph and really trying to stay at 65mph. Also, I try and be very very smooth on the accelerator and make gradual power increases. In comparison, my lovely wife is very aggressive on the accelerator even accelerating to a stop or always going 75mph and she never gets the predicted milage. Slow down and be smooth and you will have accurate numbers. If you do a Mario Andretti imitation, you will always never get the range predicted. It is just the nature of the beast.

This is a very similar route to what I did, OC to Crescent City 775ish miles on 5 and 101. I’m sure I’ll make the trek again later this year, and I’ll be more diligent on my throttle control and speed, I’ll also plan to make more stops en route. I will try 3-4 stops instead of shooting for 2 long stops.

"...EPA/"Rated" miles are simply not 75MPH on the freeway miles. Sorry if that seems misleading on Rivian's EPA part…"

Since this is your first EV and it looked like it didn't meet your expectations despite using ABRP, I'm just going to ask if you adjusted the settings to ABRP. Definitely make sure the configuration of your vehicle (battery+motor+tires) reflect your configuration. Also change the speed to more accurately reflect your usual driving habits. Did you also know that you can change the estimated amount of battery when you arrive at your destination (you can also do this in the Rivian navigation)?

ABRP is a great tool, but your vehicle has the best information when it comes to how much range you have left. Don't ignore it for some EPA numbers. Just like ICE cars, they are not as accurate as marketed.

I was also using ABRP, which was saying I would make it, it was wrong.

- Longer/fewer charging sessions (start at 100%, run it down to 10% or so, charge back up to 80 or so) which is nice if the trip and charging locations align to naturally longer breakpoints - planned stops for food or whatever. This is going to be like 180-200 miles between each stop or around 2-2.5hrs of drive time - depending on speed - and then 30-40 minutes of charge time at each stop.

Or the "hard and fast" (out of spec style) method of making shorter and more frequent stops where you might still initially leave at 100%, run it down to 10% or even 5% and then only charge for 15-20 minutes (or up to somewhere around 40-50% charge depending on how far your next charger is). This method keeps the battery in the zone where it is always in the maximum charging curve (most power for the least time). This would be more like 100-150 miles between each stop, and then 10-15 minute charges (much closer to a gas station stop with a bathroom break and some snack hunting - but just more of them).

One last thing I'd add is - ABC - Always Be Charging. If there is a charger in/around the area you're making any stop - use it. Even if it only adds 5 miles back, it's better to have it, than not. Plugin anywhere and anytime you can. This can help alleviate anxiety and, depending on how and where, can save a bit of cash if it's free L2 - and it often is.

I’m going to plan a 4 stop route and a 5 stop route, to see how they differ in total time to destination.

ABC, yeah I bungled that one the night before, thought I had plenty of charge time, so I didn’t ”opportunity charge” like I normally would, ended driving an extra 80 miles the day before the trip, meaning I left with 83% instead of 100%

I had it set for correct configuration, I just didn’t have the right consumption number, and have since upgraded to premium and connected it to the car for live numbers.

There is only 1 drive mode on the Dual Performance Max “all purpose“ I specifically asked when picking it up about “conserve mode” and was told the dual motors do this automatically now, no switching.

While you're correct, it does not have Conserve mode, it most definitely has other drive modes.

My first two trips (only like 300mi) did not go as "planned" either, and I spent a LOT of time getting ready - bottom line is it's just an experience thing. Nothing bad happened,and my plans were "fine" the issue was the reality of the ONE viable charging station along one leg of the route where I showed up and one stall was broken, there were 4 people ahead of me, the only remaining 350Kw station had a Kia Niro sitting at 100% for nearly 30 minutes until the people came out of Walmart with a shopping cart full of stuff, and then still sat in their car for 10 more before leaving. While everyone else shared the pair of 150Kw chargers left.

That one stop added an hour of extra time (plus 30 mins of charging) to the tip and threw off everything else down the line. Not Rivians fault, not ABRPs fault, not even really mine - I planned it well, it's just the reality of driving an EV right now. Subsequent similar experiences taught me the same lesson you're looking at now - I was able to plan for an earlier/shorter stop to get me past that one station, and then use a destination L2 charger at my endpoint to top up enough to skip it on the way back - I wasn't considering the usage of L2 in/around the area I'd be spending the day at, but it was crucial to make the trip "pain free". In the end, it was a minor adjustment but actually saved me a lot of time and frustration. But it's very common to think you MUST fast charge because you're so trained from ICE driving not to think about "downtime" as a place to "refuel". Once I figured that out, I didn't have to worry so much. And then about 2 months later an additional charger opened up along the route in a much better location and for whatever reason people seem to not be aware of it,Never seen more than one other person (4 stalls), it's never been down, always charges fast, and it means if I can't hit the L2 I only need about 40mi range to hit that charger and in 20-25 minutes or so I'm good to go most of the way home.

But there was definitely a learning curve - even with "good" planning. Reality rarely lines up to "expectations" - so you make a few trips, learn, adjust, and off you go. I'd still never go back to an ICE vehicle. I genuinely enjoy my R1S so much and when I do have to drive something else it feels SO good to get back and have that immediate, fluid, response of the R1S, the whole "think it" and it happens driving feel. 98% of my driving is local, and my most common road trips are now well sorted and I know exactly what to do, so aside from bumping up my charge limit the day before, I don't even think about it. Hope your EV journey works out just as well!

Ah, I see where I was mistaken, there is no conserve mode, and for options related to energy, the dual only shows “all purpose“ and “sport”

 

[Supratachophobia]

Curious what wheel setup you have?

My apologies, great piece of info to have. Gen2 22" good-looking rims, not the ugly ones.

I had it set for correct configuration, I just didn’t have the right consumption number, and have since upgraded to premium and connected it to the car for live numbers.

FWIW, you don't need a premium ABRP account to connect to your Rivian account and build a dynamic reference consumption number (and also reference speed number). You need it to see and do other 'real time data' kinda things, weather/traffic etc, but not reference consumption.

 

[CrazyOne]

I feel like rivian inflated the range numbers a bit with Gen 2. Gen 1 was pretty accurate, but. Still numbers are more realistic than some competition who shall not be named. That is a low bar though

Sorry I’m not omniscient.

 

[CarlM408]

Sorry I’m not omniscient.

I think Rivian does deserve a little heat here...a normal person might easily hop in a vehicle and look at the range number on the dash and expect to be able to drive ballpark that range at reasonable highway speeds and off they go. Enabling NAV to your destination shouldn't be REQUIRED.

EPA highway range testing for EVs clearly sucks, is Rivian working with them and other EV makers to get the test fixed to raise the bar?

Maybe Rivian needs a setting which either shows both EPA and a better guess-o-meter range on the dash. Or just the GOM number as default, so new drivers/owners don't get ambushed.

One thing you might check is whether when in All purpose mode, the rear motor is off most of the time (the auto conserve mode). It is easy to check by looking @ the drive mode display and it will show an animation on whether just the front wheels or both front and rear wheels are getting power. The reason I suggest this is we picked up our 2024 Dual Max and immediately took it on a 800 mile road trip. We found a bug where the rear motor never disconnected at any speed or acceleration. It affected our efficiency quite a bit. We took it into service when we got back and they claimed nothing was wrong but low and behold, somehow the rear motor disconnect worked perfectly and our efficiency went up by about .3 miles/kwh.
