R2 vs Model Y 70-MPH Highway Range Test (by Out of Spec)

[gecko10x]

What's the SOC most are generally using on a road trip? If you're not going to go above 80% because of charge speeds then how low are people dropping to?

I live in Idaho, my sister is west of Portland Oregon and my wife cousin is in the Salt Lake City area. There are some really dead zones on those drives. I've looked and played with ABRP to see what routes offer charging options but I'll have to look more closely at that the estimated charge and range it's been calculating.

We typically do 20% - 70% or so. I'd go lower, but our Teslas' in-car nav is notorious for over-estimating arrival SOC by at least 5%.

Rivian literally gave Kyle a whole extra set of 21" wheels to test this out as soon as he wanted. Rivian even took the car back to service and mounted them on the car at the factory so RivianTrackr could break the tires in. They accommodated him pretty well outside of letting him cut ahead of everyone else in line.

Aye did know that. Thanks for the input. Makes me wonder why did they help him?

sounds like who ever manages in the influencers in the marketing departing ask enough questions. Because if I’m Rivian you aren’t getting help from the company for anything that could paint the product negatively

he was going to make the videos anyways and he would get worse results with the other wheels

Do the Scorpions suck or are the BFGs better than anticipated? Or is it just that the people with A/S tires are driving faster and negating the range benefits?

We know the answer is yes the Scorpions suck.

So not only did Out of Spec use the wrong EPA mileage for a Highway specific test, they also ignored charging losses. This leads to "Disappointment" headlines when people go in with unrealistic expectations.

The did their standard testing protocol... but better because they tested a Model Y and R1S in the *exact* came conditions.


The point of the test is not so much to find the "true" range of efficiency of the car (too many variable), but rather to have an independent, 3rd party test that can be reasonably compared across cars. We all know that the EPA testing procedures / results are flawed, with fleet numbers coming in above, at, or below consistently, depending on the vehicle.

Ex:
Every Taycan can easily beat it's EPA figures in the real world with everyday driving.
No Tesla prior to 2024 can achieve the EPA figures without actively hypermiling.

Good points have been made, but the ethics of inflating range on sales should be considered (also didn't realize Lucid over inflated their numbers so much, as I've always been impressed with their EPA ratings).

Would an EV released in 2026 make your shopping list if it was priced over $50K, with an EPA range of less than 300 miles?

It’s going to depend heavily on where and how everyone drives. Most of our road trips are on busy interstates, where we’re rarely the lead vehicle. As a result, we experience less aerodynamic drag at 70 mph. Even our V8 Grand Cherokee averages nearly 25 mpg on these trips, so I’m not concerned about the results of this test.

I had to pick up my R1T from Minneapolis when I first got it, and drive it home to Charlotte. That is about a 1200 mile trip, I took a buddy up there with me, we played golf and swapped back and forth on drving, it was his first time driving an EV. We basically stopped about every 2 hours, just to pop out, hit the bathroom grab a drink/snack. Almost everytime we were getting finished with what ever we were doing at the stop the truck was ready to go. It only take about 10/12 mins to add 150 miles and that was on the R1T, the R2 seems to charge much better. I guess we will see how it all goes. I just took the R2 on a trip yesterday up to the mountains in NC, Boone area to play golf and back to Charlotte, 242 miles round trip, and pulled into the garage last night with 57 miles left, so assuming that 57 is correct - I would of gotten about 299 on a full charge. That will work great for me to visit my daughter at college and back home without having to ever even charge the R2 up.

BMW iX3 reports from Europe show similar drops vs stated range though still good. Lots of data points from Chris' video in Bavaria. He's posted in a BMW forum that his urban driving is pretty exceptionally good for range.

It seems to have passed without comment that the 20" A/Ts are getting substantially better mileage than the 21" A/S tires according to Rivian Roamer data. Small samples, and perhaps the car configuration isn't being updated when drivers switch tires/wheels, but the pattern is the opposite of what the EPA numbers suggest they should be.

Do the Scorpions suck or are the BFGs better than anticipated? Or is it just that the people with A/S tires are driving faster and negating the range benefits?

I always thought it was a little odd Rivian didn't show a difference in range with the 21s vs the 20" rims. Historically smaller rims meant measurably better range.

Not sure what you mean, in the Builder? It shows the range of each wheel/tire combo. Lists the 21's at 330 and the 20's at 307 on the Performance. There are pages of discussion including videos from Rivian staff explaining that the range loss on the 20's comes mostly from the rubber of the AT's.

I mean when you look at the non-performance trims. Those all come with AS tires, regardless of wheel size. Range stays the same for 19s all the way through 21s. Just seems weird.

I road trip a lot, most of my legs between charges are 100-130 miles, usually stay between 55-70% max so it stays in higher charge rates. More often than not by the time I take a bio break and get a drink it is time to leave. My first stretch of the day is usually longer as I charge higher over night.

Just from a trip mechanics standpoint, if you road trip a lot and your legs are that short and predicable and charging infrastructure is reliable you’d be better off from a speed of journey standpoint to let SOC get much lower between legs, and charge from a low SOC each time and then if you want more SOC at destination doing the longer charge at the last charging stop..

13 pages of attacking, defending, creating excuses, justifying, etc. Entertaining to watch the bickering

Hope more of you cancel and bump me up another 4 weeks lollll

Over $50k, I expect 250mi range at highway speeds, aka, 75- 80 mph for me, and 10-80% charge time around 25min. Anything less on either metric isn't a deal-killer, but is sub-par for a new EV imo.
