Anyone have R2 highway driving range to share? (I'm sure the color you picked looks great)

A fairly efficient brick shaped car with relatively high ground clearance and off-pavement oriented tires is terrible compared to what?!

Context is what gives a hot take merit, or make it meaningless.

EV9 is 2.7 over 35k miles, mostly on highway at 75-80mph

Do the math in sub 32 degrees and using 20%-80% the sweet spot of R2 charging curve. Add in the 400V charging penalty. It’s going to make distance travel in chilly weather a drawn out affair

In my experience the cold weather penalty traveling is really only around the first hundred miles of the day. I’ve done several long trips in my Tesla and R1S in sub 20 degree weather and after around the first hundred miles of the day the rest of the day was pretty much normal as everything warmed up in the vehicle.

Not my experience at all with F150 or EV6.

I’d expect the R2 to do slightly better on average/slower speeds, but at 75-80 mph it’s likely within a couple percent of EV9 due to similar aero.

The wait is over:
20” A/Ts
80% to 22% covering 131 miles @78 mph and 78 degrees F. This implies a max 100% range of ~230 miles in a mixed format…for the highway only portion this suggests 2.55 MPK at 78 mph.

so not likely to drive much over 200 miles if traveling at high speeds, maybe can squeeze out 250 miles if 45-60 mph…

Do we know if they were in Conserve or another mode during the trip? It would be another clarifying data point that would be helpful to know?

Ya. That one data point is in line with what I would expect. Though I was hoping for more efficiency.

Just need more data. And it’s coming

EDIT: adding some info:

• 20" A/Ts with only 45 miles on them when we left
• 5-10mph tail/cross wind on interstate and 5-10mph cross/head wind on 2-lane HWY
• Starting elevation 700' ending elevation of 1,200' - flat and rolling hills of the upper midwest
• All-Purpose drive mode”

This is expected and not bad at all considering the speed and AT tires. You can squeeze out far more than 250 miles at lower speeds. Averaging 78 mph is unlikely for most people IMO. Averaging 70 mph is much more likely.

Not even Rivian can overcome physics. Tesla managed to package extremely low drag-area values into the Model 3, Model S, Model Y, and even Model X — roughly ~0.49, ~0.50–0.56, ~0.61, and ~0.62 m² CdA, respectively. Rivian’s R1 appears closer to ~0.9-1.0 m² CdA, while the R2 looks to be around ~0.8–0.85 because it is taller, boxier, higher-clearance, and running large tires. R2’s efficiency is impressive but is not magical.

2.6 m/kWh at almost 80 mph is not bad, especially not knowing what wind conditions and elevation are. That is 385 watts per mile, I’ve had times in my Model S where around 80 I get 375-380 watts per mile. Consumption really goes up when going past 70.

Agreed - this is the right answer. For the record, the R2 I test drove twice on different days said it was averaging 4 miles per kWh, which is 250 Wh/mile. The test drives were a mix of highway and around town driving.

I've long said people should just assume 250 miles as the range of the R2 on the highway. Might be better, might be worse depending on loads of factors. Speed, wind, tires, temperature, etc. vary greatly. 250 miles is the all encompassing number when talking about highway range IMO.

So likely a low end of the expected range test. So 225 miles is the floor, which goes back to 250 miles is the "highway range number" IMO. Could be 225, could be 275 dependent on your scenario.

OPs wife wants 4 hour drive time x 75 mph, so far it looks like the R2 would need a significantly bigger battery to make that happen (about 60% bigger than the current 88 kWh pack). Even at 70 mph that’s not going to happen. It does become plausible once speed is dropped down in 55-60 mph range, but doesn’t really work too well in posted 65 mph zone where everyone is going 79 mph…

Yeah that was settled on page 1 we've been just vibing in this thread since getting the page count up

All the EPA stuff made it seem like it would be a bit comparable to a Model Y in range. A Model Y will get over 3 miles / kwh at that same speed. I get around 2.9 miles/kwh in an EV6 at that same speed and I've done thousands of miles to verify that number.

Maybe I was overly optimistic. I was hoping for at least 250 miles and not the 200 miles.

Relax. This is one drive and on AT tires, the least efficient wheel setup. With the most efficient wheels, 260 is totally reasonable.

Buy the 21s with road tires and you will be happy. That is if you are happy with 260 miles for 100% to 0% in good weather.

(260 miles highway range at 70-80 mph is just my estimate. One day we will get real world results which may be better or worse than my prediction.)

If this is the typical result, its very poor for a 2027 EV, regardless of tire/wheel setup.
