epa report reveals dual motor rivian r1s range

Range and power figures certified by the U.S. Environmental Protection Agency have come out for the Rivian R1S Dual Motor and have been shared by the relevant forums. Things are looking pretty good, too. Depending on how it’s optioned, owners could be seeing 348 miles of range between charges — which is actually better than the automaker had previously speculated.

One of the biggest issues holding back all-electric vehicles has been range anxiety. With everything but at-home charging taking longer and being generally less convenient than traditional fueling, EVs are often seen as less practical when it comes to longer journeys.

While your author is of the opinion that anything below 300 miles is totally unacceptable for any primary vehicle, Rivian’s base R1S only yields 260 miles between charges. Fortunately, the company is willing to sell you a larger battery pack that brings the Quad-Motor model up to an EPA-estimated 320 miles.

Considering the base model costs roughly $78,000, there’s no such thing as an affordable R1S. But the Quad-Motor variant offering a useful amount of range is brutally expensive, requiring you to splurge on the $6,000 battery pack in addition to the $8,000 setup that installs an electric motor in every wheel hub. You’ll be spending $92,000 to get the screaming 835-horsepower monster.

Fans of the brand have been eagerly awaiting the Dual-Motor R1S with the larger battery pack, as it was assumed to offer improved range and more than enough power estimated to peak somewhere around 700 horsepower.

Based on EPA testing documents shared by the Rivian Forums, we now know that the model is supposed to boast 708 horsepower. However, that likely pertains to the Performance update brand offers for an additional $5,000. Standard units that have not been issued the relevant over-the-air updates should come in somewhere around 600 horsepower.

That means the powertrain is capable of more and has been electronically neutered by the manufacturer so it can upsell you on the Performance package. It also means that people will eventually figure out how to jailbreak the R1S to squeeze more juice from the electric motors. But Rivian will assuredly complain about this, undoubtedly preferring servile customers willing to spend more money.

The above may likewise indicate that EPA testing only pertained to the Performance version. If so, that means the standard Dual-Motor R1S would likely offer improved range when paired with a larger battery pack. However, all we have are the figures outlined in the report and they would seem to suggest numbers associated with the R1S.

Depending on how customers configure their wheels and tires, the combination of the Dual-Motor and Large Battery can yield a maximum range of 348 miles with 21-inch wheels and street tires. However, selecting larger wheels or all-terrain tires brings that number down. The worst combo seems to be the 20-inch wheels wrapped in rubber designed to be taken off-road. This tracks with what we’ve seen with other vehicles, regardless of powertrain. But it’s nice to know you can still get an off-road-focused EV capable of exceeding 300 miles between charges.

Interesting vehicle but, really, it's not hard to be great at anything if cost is not a serious constraint. This is A LOT of cost.

Second, it's no great trick to use a large battery to get large range. If the internet is to be believed, the long-range R1S runs a 135KWh pack vs. the I6 at 77KWh. That's going to add up to a big difference in running mass and charging times.

  The R1S is a brick SUV; the Ioniq 6 is a sleek sedan. Why should anyone expect them to be similar?

  SCE: Sure, not the same vehicles.
  Just appears to be a tendency to talk EV range without noting the battery capacities required to get said range. To that end, a "nice" 320mi range is less as valuable if you need a huge battery to get there (i.e. long charge times, high mass, larger offset between EPA and interstate range).

Why does it seem every EV seems to have ridiculous amounts of power? Yes, I know they're heavier than ICE models but who on earth needs 708 HP? How about a nice, compact EV with, say, 250 HP and 350-400 mile range? Is that impossible with today's tech? (I currently drive a 148 HP Mazda 3 ICE and it has all the get-up-and-go I need.)

  "Is that impossible with today's tech?"
  Almost. Right now battery size, range, output , and price are generally all positively correlated.
  A 200hp EV will have a relatively small battery and smaller range. I guess you could gain some range by limiting output of a big battery to 200hp but it would still be $90k from the battery cost.

  Well, Mazda dipped a toe into the waters of a minimalist EV with the MX-30. It has about the same power as your Mazda 3, but unfortunately, the range is less than 100 miles. That's out of a 35.5-kWh battery, which is less than a Nissan Leaf has, and about half of what a Chevy Bolt has. I think this is a decent idea, but only works for a limited set of consumers. If Mazda brought it back with a battery around 50-60 kWh, that would improve the range and also facilitate more power, which would make it much more marketable. But it would also add a lot of weight - maybe 500 pounds or more. So it's a tricky balancing act. The limiting factor for EVs is still battery weight, much as it has been for the last ... 120 years?

  Commenters on a blog for auto enthusiasts never did clutch their pearls over ICE vehicles with big horsepower. In fact, we like that.
  But an EV that blows the door off any ICE vehicle you can afford? How DARE they!?!?

  It's just so easy to add more power to an EV with the same battery.
  
  Tesla rebirthed EVs by showing that they don't need to be slow, awkward golf carts like the 1970s Citicar, and Nissan showed that they could be affordable.
  
  The upward power trend is also cultural, as we see across the board with ICE cars. You can buy 800-HP cars and trucks from a variety of mfrs, and people are willing to pay for it.
  Personally, I'd prefer more range and less power, but the battery weight required for that range means you still need some power to move it along. The physics isn't totally favorable for EVs yet, in terms of energy density and recharge times.

  I own an EV that's used almost exclusively in the city, and I don't think ranges below about 150 miles work well even for city runabout use. 150 miles is the practical minimum and the MX-30 (1) didn't get there and (2) was too expensive for what the buyer got.

Theflyersfan The two Louisville truck plants are still operating, but not sure for how much longer. I have a couple of friends who work at a manufacturing company in town that makes cooling systems for the trucks built here. And they are on pins and needles wondering if or when they get the call to not go back to work because there are no trucks being made. That's what drives me up the wall with these strikes. The auto workers still get a minimum amount of pay even while striking, but the massive support staff that builds components, staffs temp workers, runs the logistics, etc, ends up with nothing except the bare hope that the state's crippled unemployment system can help them keep afloat. In a city where shipping (UPS central hub and they almost went on strike on August 1) and heavy manufacturing (GE Appliance Park and the Ford plants) keeps tens of thousands of people employed, plus the support companies, any prolonged shutdown is a total disaster for the city as well. UAW members - you're not getting a 38% raise right away. That just doesn't happen. Start a little lower and end this. And then you can fight the good fight against the corner office staff who make millions for being in meetings all day.
Dusterdude The "fire them all" is looking a little less unreasonable the longer the union sticks to the totally ridiculous demands ( or maybe the members should fire theit leadership ! )
Thehyundaigarage Yes, Canadian market vehicles have had immobilizers mandated by transport Canada since around 2001.In the US market, some key start Toyotas and Nissans still don’t have immobilizers. The US doesn’t mandate immobilizers or daytime running lights, but they mandate TPMS, yet canada mandates both, but couldn’t care less about TPMS. You’d think we’d have universal standards in North America.
Alan I think this vehicle is aimed more at the dedicated offroad traveller. It costs around the same a 300 Series, so its quite an investment. It would be a waste to own as a daily driver, unless you want to be seen in a 'wank' vehicle like many Wrangler and Can Hardly Davidson types.The diesel would be the choice for off roading as its quite torquey down low and would return far superior mileage than a petrol vehicle.I would think this is more reliable than the Land Rovers, BMW make good engines. https://www.drive.com.au/reviews/2023-ineos-grenadier-review/
Lorenzo I'll go with Stellantis. Last into the folly, first to bail out. Their European business won't fly with the German market being squeezed on electricity. Anybody can see the loss of Russian natural gas and closing their nuclear plants means high cost electricity. They're now buying electrons from French nuclear plants, as are the British after shutting down their coal industry. As for the American market, the American grid isn't in great shape either, but the US has shale oil and natural gas. Stellantis has profits from ICE Ram trucks and Jeeps, and they won't give that up.
