I'm tired of EVs using the electric usage to gut their interiors of $50k+ cars.

I like the Rivians I've seen. They're actually, y'know, a truck as opposed to a k-hole hallucination. You can lift stuff up and over the bed near the cab.
gkanai•1h ago
The R1 is a body on frame, so a traditional truck chassis.

This new R2 is a unibody- so more of a car, less so a truck

Can they fix that web page? That was so awful to try to get any info.. Just scroll, scroll, scroll and still just a bunch of big pictures and no meaningful info.
mholt•1h ago
If you look at the R1 pages, you'll see those pages, though scroll-heavy, at least contain more useful info. I'm hoping that after R2 is actually available to order, that they'll update the page with more information. It's still early.
cebert•53m ago
The scrolling was so bad I had to close the page when I was actually interested.

Length and width wise, it's smaller than a Model Y. It's deceptively styled to look a big boy car, but it's a matchbox. That's why no reviewers will show themselves or anyone else towering over it. It's for those who want a big car, but without all that space. Rivian calls it a mid-size SUV, but that is straight up bullshit.

I miss the days when men looking to compensate would buy sports cars. It wasn't any less ridiculous, but at least they (edit: the cars) were better looking and more fun to drive.

_carbyau_•1h ago
I guess it depends on what they were compensating for. Up until the 80's and 90's at least there was more association of racing cars with road cars that you could buy.

So that would associate you with the (A man's manly-man maybe?) driver of that car.

But now race cars are not really much like a production road car. And those older men with money don't necessarily want to be like the ever younger drivers being employed to win races.

As you say, ridiculous, but at least the sports cars were cool.

Based on the published dimensions, it's almost the exact same size as a Toyota 4Runner - which I'd consider a midsize SUV.

cosmic_cheese•1h ago
"Matchbox" is rather hyperbolic and would better match the upcoming R3/R3X which is around the size of a VW Golf (though that still isn't that small… Honda Fits, kei cars, and Fiat 500s are smaller still).

It's about a foot longer than my crossover, which is about the same size as a RAV4 or CR-V and there's no way I could call it tiny.

DennisP•1h ago
If you want to see a reviewer next to it for scale, Doug DeMuro is 6'4" and has what you're looking for, from various angles over the course of the review. Looks like a reasonable size to me.

Haptic steering wheel thumb-wheels instead of actual buttons? Hell no. Full pass. And we're in the market for a vehicle like this in the next year or so, looking hard at Santa Fe Calligraphy, or Outback XT (similar size, similar price tag, AFAICT). No physical buttons = no sale.

The R2 was the first time I seriously thought about spending up on a vehicle.

It looks good.

But $45k++ is just wild to me. It seems like the market is undervaluing used EV’s, so hopefully the depreciation curve will bring these down to $30k in a couple years for us old-school folks who prefer not to have a $1000/mo car loan.

toomuchtodo•1h ago
Average price of a new vehicle in the US is $50,000. This is priced appropriately considering total cost of ownership delta against a combustion vehicle. Rivian needs more volume for prices to decline from manufacturing efficiency at scale.

Someone1234•1h ago
People keep repeating this uncritically. There is a car-debt crisis, and wages haven't kept up with house/car costs.

We have one person saying "well in Californian wages..." and another saying essentially that 50K isn't a lot of money when the average SALARY is $66K/year.

freetime2•1h ago
I also believe this $50,000 stat is the mean car price which is likely to be pushed up by luxury car sales that cost 2-4x what a typical car costs, whereas a median price would give a better indication of what most people are actually spending. I did a quick Google search and wasn't able to find any data on median price, though.
JumpCrisscross•1h ago
> There is a car-debt crisis

To what degree is this caused by car prices versus Americans' compulsion to keep buying new cars? Anecdotally, the folks I know struggling with car payments are almost exclusively in the latter bucket. But I'm open to having my mind changed with data.

I'm a little confused why you think that's wild; It's pricing is inline with other BEV's in the Canadian market at least; it's comparing with the Model Y, the Equinox, the Blazer, the Mach e, the Ioniq 5, the EV6, the BZ4, and the Aryia.

Typically speaking you're going to spend $10,000 to $13,000 more then an equivalent gas car for a BEV vs a comparable gas car in Canada.

cchance•21m ago
ya same, i can't see spending as much as i did on my first tesla 5+ years ago, the depreciations just too steep, hopefully that holds for rivian too and i'll pick one up in a couple years the R2 is really nice.

That said, china BEV's are 1/2 the cost even accounting for import costs to the USA lol so sort of points toward a issue with US companies at the moment

Do they depreciate any worse than their gas counterparts? You’re also saving money on gas and maintenance - that’s gotta count for something, no?

I really reality wish rivian create a better self-driving technology soon and make a proper competition to tesla. Rivian cars are so nice and well designed.
api•1h ago
Honestly just decent smart cruise and lane keeping is good enough. Concentrate on making a solid long range reliable EV is the best way to compete with Tesla in the short to medium term.
freetime2•1h ago
Personally I'm in no rush to have self-driving capabilities in my car for at least another decade or so. I'm pretty happy with the current ADAS systems found in most cars like adaptive cruise control, lane keeping, and collision avoidance - and happy to just see incremental refinements to those systems.

At some point I want a self-driving car, but I'm happy to let Waymo and Tesla users test those systems for another 10+ years before I personally start using them.

JumpCrisscross•1h ago
Are you buying a car in the next 10 years? I’m in a similar boat. But I’m irrelevant to the car market because I’m not buying until I can buy a Level 4 car.
freetime2•1h ago
I just bought a new car, and will probably buy another 1-2 cars in the next 10 years. My ideal upgrade path for cars is:

* I wanted my most recent purchase to be a PHEV

* I want my next purchase in roughly 5 years to be an EV (hopefully solid state batteries are available by then)

* In about 10 years I am hoping that I can buy a car that can self-drive most of my trips door-to-door

One thing I'll add is that I live in an area that gets a ton of snow, and current ADAS features are basically worthless in snow. They all turn off once the sensors get covered in ice, or when lines in the road are no longer visible. So I expect that even in new cars 10 years from now, I'll still need to take the wheel to drive during winter. Basically the features are nice when they work, but I'm still going to want to car that is first and foremost designed to be driven by humans.

JumpCrisscross•1h ago
> I live in an area that gets a ton of snow, and current ADAS features are basically worthless in snow

I live in Western Wyoming. While my Subaru won't drive itself in a blizzard, the radar is still useful.

My plan is to wait until I have something that can drive itself unsupervised in clear weather. Given that's Waymo today and maybe Tesla in ~5 years, I'm figuring something should be on the market that fits that bill within 10, which is how long I'll try to hold onto my gas-burnig Subaru.

nradov•52m ago
What radar? I'm pretty sure that Subaru uses only cameras, no radar.

https://www.subaru.com/eyesight.html

n8henrie•1h ago
Agreed! But I have to say, lane centering and adaptive cruise control have been amazing, coming from a previous vehicle with neither.
fluidcruft•1h ago
The main thing I think about self-driving is if it truly were self-driving and you could sleep in the car while it drives to a destination overnight. Even if it were only highways. That would be really cool.
nradov•57m ago
I can't sleep in a moving car anyway so that's of no value to me. If I'm going to be awake anyway then I might as well drive.
bee_rider•1h ago
Self-driving seems like something where car companies shouldn’t all “reinvent the wheel.” A couple of the bigger car companies have projects on this, right? Maybe they could share.
JumpCrisscross•58m ago
> A couple of the bigger car companies have projects on this, right? Maybe they could share

Why should they? We're already approaching geopolitical competition at this problem, given self-driving cars and self-driving self-propelled guns and the like are basically technological twins.

paradox460•49m ago
It will probably follow the same pattern as ADAS. Bosch or someone will develop a package, sell it to car manufacturers, and it will become widespread
DennisP•1h ago
They're working on that. They're partnering with Nvidia and the R2 will get upgraded hardware for self driving in the fall. I couldn't tell from the website if making a reservation now lets you wait for that.
joshstrange•1h ago
No CarPlay, not interested.

I wish Rivian would stop trying to emulate Tesla on this front and add support for CarPlay. I don't want your UI.

I actually like the look of the Rivian and this is something I'm somewhat in the market for (or will be in the next few years) but I won't touch it without CarPlay.

hartator•1h ago
Yes, copy FSD instead that no CarPlay cult.
JumpCrisscross•1h ago

They are. It’s also subscription based, however.

(For what it’s worth, my friends with Rivian are fine with its phone interface. As are most people who own Tesla’s fine without CarPlay.)

Apparently there's a aftermarket device that will add Android Auto / CarPlay support by selectively taking over the infotainment display:

https://evplay.io/shop/ev-play-for-rivian

(I can't vouch for it, just something I stumbled upon recently.)

maxdo•1h ago
as a tesla owner, all I can tell, carPlay is ugly child was born due to EU car makers, not capable of building proper infotainment system.

I want to drive, not constantly connect/accept privacy etc. Especially if that is a $100k+ car.

When i get into the car, the last thing I'd like to know how my car is getting connected to my phone, if there are any issues, especially if that is not my car.

I love how my car knows that in the morning i go to work, and wednesday evening i go to yoga, and put GPS, with best traffic options. 0 touch, all super seamless. No phones involved.

freetime2•48m ago
Looks like a great car. As Marques Brownlee puts it [1], this is Rivian's "Model Y fighter". And I personally find the R2 to be much more appealing than a Model Y in terms of size, shape, and interior.

But we have been misled so many times about EV prices prior to launch, I think it's important to wait until we see what it actually costs for different trim levels before making comparisons to the Model Y. That $45,000 price they are throwing around could very well be for a trim that isn't even available at launch.

And anyway if I were going to buy a new compact crossover today, I'd probably lean more toward the RAV4 PHEV. It's an EV most of the time, I can refill it up with gas during long trips, it's got tactile buttons, and it has carplay.

The RAV4 Prime is extremely hard to get if you live outside of SoCal and maybe a few other areas. I'm in the southeast and a few years ago the local dealer told me that this entire region is only allocated a few Prime's each quarter. Even today I've never seen one in the wild.
seattle_spring•7m ago
Not only that, but it sounds like dealerships are still hardcore ripping off people who want to buy a RAV4 Prime. $20k over MSRP, refusing to sell without add-ons / warranty, etc.
pstuart•23m ago
> It's an EV most of the time

Nowhere on the Toyota site did I see anything about range on battery only. Still, I wouldn't mind having one.

I settled for a refurbed Leaf and have only needed an ICE vehicle twice, because of cargo capacity, not range.

freetime2•18m ago
Toyota is claiming "up to 52 miles on a full charge" on the recently announced 2026 RAV4 PHEV [1]. For me that would be enough to cover the majority of my trips.

Looks like I was mistaken though and you can't actually buy the 2026 model yet (and the Toyota website still shows the older 2025 model). And as another commenter pointed out, it may not actually be possible to buy the older model either due to insufficient production.

dyauspitr•40m ago
That 300+ miles means nothing without more specs. What’s the size of the battery? The usual 130-140 kWh?
mrcwinn•38m ago
Former R1S Gen 2 owner. Love this brand and I want to love the car, but the quality and constant maintenance issues were unacceptable.

Rattles, a door mirror motor breaking, doors that wouldn't shut properly, door weather stripping that fell off, a door that just wouldn't open, panel alignment issues, some kind of screaching-to-a-halt-and-terrifying-my-family auto-brake that Rivian never figured out after reviewing log data.

Oh and did I mention the fans or heat pump that sound like a ROCKET LAUNCHING?! At a park one time someone asked me if something was wrong with the vehicle. Nope, that's just the terrible fans they chose!

Insult to injury: someone rear ended me. Insurance "covered" it, but the local collision center --- my only option within 6 hours --- charges a 2X rate for EVs that State Farm would not cover. So a $14,000 MINOR FENDER DENT turned into $7,000 out of pocket for me.

If you look at /r/rivian, it's a near constant stream of issues. While Rivian did expedite service center visits for critical issues, other times repairs were months out. And as the R2 scales, SC growth will probably trail for a while, and so I really fear for the experience early adopters are in for.

I am rooting for them but for me personally I would not consider another Rivian.
