You two are great together as presenters! I enjoy watching and learning from your detailed analysis. Great job guys! Would like to also see Jordan do a standing backflip🙂
That accessory air compressor looks exactly like the ARB compressor I bought specifically for pumping up tires on my 4x4 after they've been aired down for sand driving. ARB is Australian, like the part you showed.
I think we need to push this vid to everyone. I would surely enjoy to watch that back flip.These tear downs and detailed videos are great. Keep up the fantastic work.
Wonderful channel, and I’m certainly no mechanical engineer. Munro is so smart to employ such hugely well-educated and articulate young people. One does wonder how the USA can produce people of this high calibre at the same time as the USA has such enormous societal problems. So it is encouraging to see, from outside, that parts of the Nation work so extremely well. Good luck to the USA!
These two are the "A" team for presenting. Great chemistry, they compliment each other and it is apparent you get along. One other thing, Rivian is definitely over engineered. anyone who got the first generation has a vehicle probably worth twice if not 3 times what you paid for.
I didn't like Jordan when he started with the fridge, but he has grown a ton, and the dynamic with Scott is excellent. I really enjoy their videos, great job!
Really appreciate the added insight on how you would improve things. You two make a great team; presenting together makes both of you look even more insightful.
I'm not a mechanic, do fiddle with my truck sometimes but mostly craft/maker stuff and always enjoy learning about systems and production components and processes.
Yep, they appear largely symmetrical other than the pivot nut. Does the bolt have a shoulder so the two holes sizes are the same? Fully symmetrical? Or a common casting to be machined?
Very informative. Thank you! As I am purchasing a Rivian the more technical information is out there the better the community will be. All power to Jordan and Scott.
The rear LCAs are machined on both sides because they are the same part, just flipped for the other side, so it makes sense to be machined on two sides
My thoughts are that the reason they have two compressors is that the one used for the air suspension might not be rated for high duty cycle. And that if somebody was using the air compressor for extended periods or just using the air facility a lot. The service life of that compressor could be exceeded in a short amount of time. The cheaper compressor may actually be lower volume and rated for higher duty cycle.
Regarding the redundant machining on the Lower Control Arms: Are they maybe Mirrored (or are otherwise mostly the same)? so they have the same Part for both Left and Right, and the side where it goes is decided in a diffrent step where this blue Nut is added? Still Savings potential there, but this would allow for some more flexibility
You guys vibe so well together and you're so articulate. I bet you would do well if you guys got together and did a podcast; where you could talk about everything and not just cars. I'd certainly watch it.
I would worry about the security the electric parking brake can provide in the Rivian compared to a mechanical one on other vehicles in offroad environments. It is common knowledge you park with your rig locked into 4WD when parking on steep offroad areas. This allows all four wheels to participate via the drivetrain in keeping the vehicle from moving. Seems the Rivian would only use the back wheels, given the greater weight of the Rivian, it might slide down a hill dragging the back wheels the whole way. I've seen it happen to Jeeps that were parked in 2H, it can and will happen with the Rivian. Would be nice if that motorized park brake was on all four wheels. Maybe this is a change that can be put into a future model of theirs.
Great work , Both these guys work well together , and no doubt both could work well with anyone on the Munro family. Would love to more videos with Sue and Sandy. Seems like Sandy doesn’t mind passing the ball to some of the younger talent , I am sure in Sandy’s mind that if in the near or far future if his health falters he wants to have several talented young people keep the company moved forward. Please do give us a backflip maybe an unexpected one in front of Sandy and Sue to get the looks on their faces. Cheers to all at Munro.
The extra threaded holes are probably non-handed parts in a handed installation. Also interesting the origins of some of these parts. Struts from Poland, air compressors from Australia. Quite a lot of miles travelled before assembly!
I love to see the analysis of what is but also the considered thoughts about what could be. Integrating components saves weight, adds strength, simplifies assembly, and reduces production costs.
In some cases it also increases repair cost, but Munro is never concerned with that - their purpose is to reduce manufacturing cost, regardless of the consequences for the vehicle owner.
Great video, I like to give a suggestion as well, it would be nice while you are speaking about the different parts also share where they are made and who have made them, (as some of them can be discovered from the stickers on them even in this video).
Our Czech Tatra trucks have had the pneumatic suspension since I was a boy - at least 50 years. Also their rear wheels were always on half-axle driven from the central column, so they were roding on their outer wheel rims when unloaded. But sometimes since 1980+ uears they added that pneumatic suspension to those rear wheels so when the truck was empty, the air pressure cushion got lowered and this this old funny setup was fixed and imho is better system than other trucks in general.
Use the same compressor for suspension and for air inflation? Yes - VW in 2004+ with the Touareg. However, if you want to use the compressor a lot, having a separate air compressor that is not critical to vehicle functionality is a nice idea.
best lines of the review "you just wag your finger and go these guys" and "id really like to see a tube stuck to the cradle". you guys are awesome, thanks for all the knowledge and the fun.
Those front struts are a joint effort: the upper air spring part is from "United Kingdom" (1:46) and the damper section (Monroe-branded) from Poland. And about the 11th-hour aux air compressor: neither it nor the main suspension one are actively cooled, so if there were only one compressor, that leaves the possibility of the main one getting cooked from, say, pumping up a huge innertube at the lake, that would leave the truck dead in the water so to speak. So having the aux one is insurance against the bad "optics" of a Rivian on a tow truck...
air tanks have moisture and corrode over time I would want that to be a replaceable part and not part of the main structure. some times i really think there ideas are making something faster and cheaper to built but its also a cheaper product with possible long term problems.
I think Tesla should have updated the Citroen hydraulic suspension system. With two electric pumps there would be no need for a hydraulic accumulator. It could power suspension, brakes, steering and even give a basic active suspension.
Thank you! I’ve owned cars without park pawls for over 40 years……with only a few edge case events😎 Those small redundant bosses on the suspension look like mounts for height sensors?
My worrirs about using only the brake: People are cheap and skip maintenance regularly. If the pads or rotors are too worn, you want that redundancy. Backyard mechanics will need an option when maintaining the rear brakes. The weight makes most tire chucks useless, hopefully they figure that out
Great job. My thoughts..is it possible the rear lower arm is a single forging designed to be used on both sides of the vehicle? The 2 arms zip tied together look symmetrical…if so, that would explain the pad and extra machined surface and holes that are not being used. On the accumulator, I do agree with the concept of combining it with something that is preexisting, just not sure the rear subframe is the best idea. Tank failures are obviously pretty rare, but if a tank DID fail, not only would it mean replacement of the entire rear subframe, but it could possibly represent a structural integrity issue on such a highly loaded component.
Are the lower control arms and struts the same part numbers? Is it possible those additional machined perches are there so the part can be used on either side?
For the 'park', in Europe most cars are manual (Due to our myth of 'manual allows for more control'), we just have an electronic parking brake like Tesla. With it off, the car rolls away. No transmission/engine 'parking'. 🙂 Its always been that way so I don't really see it being an issue. My dad's 2014 Peugeot has an electric in-caliper parking brake as well. It's very common.
Bumpers make great air tanks. More tank air the better. It's all about CFM. Though, even on suspension, and this is a question on the Tesla, how do you get rid of water accumulation in the air tanks? Is there an auto purge? As to tires, airing up/down, on a 100K truck, that should be a 'button' on the dash. Central Inflation System.
17:50 Consider the two motor variant and the R1S. The suspension could be designed to carry the components for the two motor variant of the R1. There might also be a different component configuration for the R1S using shared parts.
