R1S vs. R2 vs. R3 size comparison

[cjones1130]

To me, it would look more proportional to have a an additional 2 inches. The 9.8 inch clearance is fine but a little more on water fording depth would be helpful and matters to me. At 69 inches, it is an inch shorter than the Bronco Sport. I'm sure some combination of after market stuff will allow me to tweak the look and function.

Maybe carsized will get a R2 and R3 on their site for nice comparisons.

Straight from the carsized page:
"Let us know about the cars you'd love to see on our website by contacting us on social media or dropping us an email to info[at]carsized[dot]com."

For R2, you can just pick the current generation BMW X3. It's virtually identical to R2, a couple inches here or there.

Depends on how many people you have with you, but for myself and the wife and our dog, we remove the 470's second row seats which allows 5 foot 10 me plenty of room in there and a full size air mattress fits perfectly. Now, if you're going with more people I can see why that is impossible haha

I thought about a platform and fold the second row flat because tumbled there still isn't enough length as well. Unbolting is pretty permament but the GX has more head height than the 4Runner which is nice for sleeping in it. Now one of my kids is driving it around so I'm less motivated.

Hard to say where the R2 will land for off road capability. The XJ and Grand Cherokee are unibody as well so I don't think that necessarily matters. The fully loaded Unibody Toureg had locking diffs and was a beast without straight axles and the Rovers are also IFS IRS. But yea, Toyotas are where it's at for reliable offroad capability.

Indeed I saw that after my post and sent them details.

Give us a R2T Rivian!

YES!!! Give the people what we want!! Since R2 is a stripped down version of the R1S, do the same with the R1T.

R2 isn’t a stripped down version of the R1S. It’s an entirely different vehicle in a different size class.

R1T already has the bed size of a compact pickup like the Maverick. A smaller version of the R1T has no market in the US

it could be like a Santa Cruz sized truck!

Hyundai Santa Cruz has terrible sales. Not one to emulate.

Maybe Ford Maverick size. But broader problem is that electric pickup sales volume has completely collapsed - don’t really want to make an even lower margin version of that right now. Mass Demand just doesn’t meaningfully exist right now

Tesla owner here (M3 SR LFP and MY LR AWD). I really like the Rivian M2. Perfect size for my wife and me. The problem is, if there is no repair/service facility within +150 miles of where I live (south of Tucson, Rivian service is in Phoenix) I can't consider any make vehicle for our use.

​

Yeah, grew up in Tucson and my buddy has a hell of a time getting his R1T serviced. I’m surprised the Old Pueblo hasn’t gotten one yet.

2 inches taller would significantly impact drag coefficient and expected range.. which would then mean a bigger battery size needed to deliver on competitive range.. which would then mean a heavier and more expensive vehicle to meet the 300 mile minimum range promise... which then either lowers margin or makes it less price competitive, nullifying the point of making the vehicle

This is just not true at all. Ride height has almost no affect on drag unless you hit very specific points. (Points where you go so high or low that you interrupt airflow around the vehicle.) It has a larger change in downforce, which really has its largest effect on handling. And while this certainly matters hugely on an F1 car or a hyper car, it's not nearly as big a deal on your average road car.

Below is a graph from racecar-engineering.com that shows the relation. Obviously, these are stats for a hyper car, so it's not a 1:1, but even then you can see how little clearance affects drag, even when looking at the smallest levels of clearance, where it most likely has the most effect.

So, assuming that the R2 is aerodynamically sound for its current clearance height, a 2in lift on a vehicle that already has 10in of clearance isn't really going to affect much.

The poster I was responding to compared the R2 to the Bronco Sport, which is taller than the R2 but has an inch less ground clearance.

Because of that I was talking about taller due to physical car size, not just a 2 inch lift. Agree that if it was just a 2inch lift it’s likely only a 2-3% impact at highway speeds - but a physical 2 inches in physical body height with this boxy design would require major design innovations to not kill efficiency

Huh, weird. Then I wonder why does Rivian make the effort of dropping into low ride height on the highway and also in conserve mode?

Yeah I can see it not making much of a difference in an F1 car that is already way low to the ground. And that test above is for less than an inch increase in ride height. I'd be wary of extrapolating it to Rivian and their much higher ride height.

I don't think that F1 drag chart means anything to a vehicle like a rivian

They responded with:

We need to organize and specially photograph an actual vehicle. Most probably it will not be possible before October. We will let you know.
