EPA Range Finalized / Published (R2 Performance)

[Hereforthesnacks]

Let's get one thing straight, there isn't a single production car (EV or otherwise) that has real world numbers that match EPA-certified numbers perfectly. Instead

Eh? 2024 Kia EV9 GT Line EPA range + 270. Real world = 270+ over 34,000mi.

EPA ranges are not great estimates of real life. But this is too absolute of a statement.

EPA efficiency has a lot to do with tires. These are not comparable vehicles because the top speed of the rivian is very low. The tesla goes 155mph and uses tires rated to go that speed

The cybercab is supposedly the most efficient EV ever certified but the max speed is around 85mph

R2 performance is more comparable to AWD model Y but of course tire size is different

No one is going 155mph so it is fair to compare Performance with Performance.

As someone who is cross shopping a Model Y Performance to the Rivian Performance, they each have their trade offs and as I suspected highway real world mileage will be less on the Rivian due to the drag.

I've got to factor that in, because I regularly drive between 70-80 miles an hour. The model Y is similarly penalized by tires...and I suspect changing over to a 19" aero wheel would increase real world range, since we see those metrics reflected on the other trims.

That said, they are both really competitive in this area and share vehicle to load capabilities.

I predict 75 mph highway range is going to be well under 300 miles. I bet around 260, which isn't horrible, but way less than I need. Especially when on a trip and charging 10-80 (using only 70% of 260 between forced refueling stops).

And then there is the bad weather penalty...

 

[Hereforthesnacks]

Simply having 800V isn't really much of a game changer either. It's

The ability to charge from 20-80 in 20 minutes really is a game changer. Holding a charge at 200-240 kwhr for a whole charging session rocks.

You can basically charge up by ordering food and getting it. No getting back to the car and waiting. 30-40+ minutes may not seem like much more, but once you get used to 20, it’s huge.

Getting to 5 minutes will take many years in the US.

Yeah, that's 3 mi/kWh, which seems pretty realistic for R2 at 75mph. I'll be optimistic, but it's hard to see it being a lot better than that.

Drag is a huge part of the equation, but many other factors also play in like motor efficiency and tires. The shape does not paint the whole picture.

My opinion is that the R2 will not likely hit 330 on the highway (nor is the rated range really reflecting that) but getting real world 270-300 miles depending on driving behavior is perhaps not entirely out of the question. Given the price, good enough for me but YMMV.

EVs get their best range in city driving, their worst on the highway. 330 miles is an estimate of a combined cycle of both city and highway, so you're very much right that a highway-only cycle wouldn't result in 330 miles.

The drag coefficient or whatever efficiency of the R2 may be really good. The EPA numbers are average at best. 330 EPA miles means less than 300 real life miles. My R1T large DM does better than that, granted with a lot more battery. My wife's Tesla M3 gets 320 real life miles.

I have a hard time believing it will be that great based on the data we already know. R2 COD is 0.29 vs Model Y of 0.22. That's significantly worse which of course is obvious as it's a box not an egg. That is only one part of the equation though as the frontal area of the R2 is going to be larger as well, further reducing efficiency at highway speeds.

I don't doubt it will be very good under 55 mph, probably around 300 miles. The concern is how is it at 70+ mph for those highway road trip stretches. I imagine it will be drastically worse, like 250 miles maybe. When I put the data into Gemini it comes back with exactly that - 250 miles at 70 mph in good conditions. 2.8 miles per kWh or 350 Wh/mile.

There could also be some better drivetrain efficiencies we are unaware of with the rear motor bias on the R2.

I hope I am pleasantly surprised!

I’m down the queue on the R2, so at least I’ll get the benefit of real life range testing. Car and Driver has a good 75mph test, I’m sure others will too. My driving is in CA, so temps aren’t much of an issue. I’d be happy with a solid 250 mile road trip ranges with the 21” tires. I’m 90% home charge, have solar.

If they used the 5-cycle test and not the 2 this in real world will never get over 300 miles. The stated range is the actual. This is why BMW, Porsche and MB exceed the rating. This is also why the R1 got very close to exceeding the published range. Real Range on a full change will be closer to 280. In my Model Y I hade I never got the rated range, and tesla uses the 5-cycle test. This is actually disappointing from Rivian. The BMW iX3 will get in real world testing closer to 500 miles than 400.

If you take a performance tesla and swap the wheels/tires for the same combination that comes with AWD models you get the same efficiency.

Most of sea level CA is perfect for EVs.

there's no gaming. There are different test cycles to run that could yield different results. Any OEM can choose to submit a report to the EPA with the most favorable numbers

This is literally what "game the system" means. But yes I completely agree with you that every OEM engages in this behavior.
