New Romanian Touring Car Prototype!?

Added: 2026-05-31

[00:00:00]Let's move on to the shaft driven car.

[00:00:03]>> Yeah, let's let's move on to this one because this is the one I think even I'm more interested about. Uh so let me bring up to the stage. So we have uh Hyro inertther. So I think it's a brand called Hyro and they call this car the inert.

[00:00:20]So this is a 10 scale touring car. Uh it's still in a prototype phase. Um it's a Romanian startup company.

[00:00:29]uh led by Vlad Shiroichi. Um and uh basically the reason they're calling it uh Inertor is because apparently the suspension system um utilizes inert um shocks. I'm trying to find like a good picture where you guys could see it. Well, um, okay. Here, here we have a good enough picture. So, at least the press release says that the suspension system uses inert shocks. Um, and if if if this is true, then basically what they was mean is that instead of having fluid shocks, you have um a mass uh that is put into a ball screw. And when you push the ball screw, it builds up inertia in this mass.

[00:01:28]And uh basically what it does is every time you push it, it tries to stabilize itself in one direction. So if you have vibrations that go up and down on the car, it tries to always counter the vibrations in that direction.

[00:01:44]Uh so it works as a damper in that sense. Um, and as you can see here, they've attached it to the car with uh a rocker. So, you have um a a ball stud uh a turnbuckle link type of thing that attaches to a rocker and then you have a much longer distance between the rocker point and the shock to create the higher movement mo motion ratio to basically I think they might even have like made the motion ratio in a lot of ways uh like do I say negative or like whatever, but basically so that the shock moves more than the arm. Um, and uh that's why they use the rocker, I think, to make the inert move more to get the get the forces to a level that they can work with with the inert. Um, so that is probably one of the weirdest things about this car. Uh, but there's a lot of other stuff, too. So the next thing is that this features a shaft a driven car. So basically uh similar to the original automatics is they have in the rear they have the spurgeear then they have the motor next to it and then you have on both front and rear you have these diff cases uh that are connected. Um I do not know um that if they have like a floating um system because the original automatics what they did was that they had these diff cases on both ends but the diff case was allowed to float on top of the sort of the what you call them like bulkheads.

[00:03:42]So when you went on power, we know that the the shaft tries to pull the car in one direction.

[00:03:50]The idea on the automatics was that they was trying to counter this pull by allowing the diff to move just a tiny bit. And this sort of uh acceleration or torque applied by the shaft would be countered or damped by this diff moving in the in the bulkheads. I don't know if this car incorporates that, but it was a really cool feature of the automatics.

[00:04:16]At the end though, uh I think it never worked out for them. I I feel like it's so difficult to make the shaft work for touring cars because they are so sensitive at such high speeds. So, you will always have a slight pull to the side. Um and I think it's impossible to fix. Uh I feel like the inert thing is cool. I feel like the whole re red trying the shaft shaft driven cars are cool. Um they also have like this super um narrow center of gravity thing because if you see they have the steering servo here in a lot of the touring cars they have the steering servo horizontally. On this one they have it longitudinally.

[00:05:02]Um I don't believe that there's any other reason to do this except for try to have uh a more centralized placement of mass. So as you can see normally the motor is also horizontally. Now it's longitudinally they can pull the battery in a lot because the shaft is not as wide as the whole diff assembly. So they have a very narrow uh or like very centralized mass longitudinally. And then they have the shaft driven car.

[00:05:34]Then they have the inert uh shocks. So plenty of uh cool things on this car. I don't really know if there's like other things >> to talk about, but >> I just have one question. Uh the shocks, inertia shocks, you mean right?

[00:05:54]>> You said inerta and inertia. Is there a difference? Just before I go on to my next question. So, so inerttor means a uh basically a machine that has a ball screw and then a mass that inside the mass there's like threads. So basically it's kind of like a screw that you push into this mass and uh because the mass cannot move it starts to spin because of threads. So that is an inert and the inertther uses inertia which is the mass rotating um that is inertia. So this inertia basically resists then further movement by this screw. It dampens the movement by the screw. So the when the shock goes up, a screw is screwing in or I'm I'm >> the screw is the screw is pushing in and then the mass starts to rotate.

[00:06:57][laughter] >> So there's no oils in there. There's no >> um well the thing is that >> the thing is that I would really have to like study this to like understand everything. I I would imagine that they have both oil shocks and an inerttor. That would be the the the way the F1 uh like F1 did it. But the thing is like I the the pictures I can't really see everything and like I would need like a manual or something to see all of that.

[00:07:39]>> Gotcha.

[00:07:40]>> Um >> that's crazy.

[00:07:42]>> Yeah, I think there's some of these pictures they they have something that's hanging on there, but I don't really know what that is. Um, that could be the inert. They could also have done it in a different way, you know, like you don't have to do it in in this way, but that's the original idea of the inertther. And this came came about after Formula 1 had electrical damping systems. So, the only thing that you couldn't do with a piston and um piston and oil damper was to have inertia within the system. So then they basically tried to recreate what they did electronically with those electrical dampers doing that mechanically and they transferred the electrical u uh physical like uh expressions like so the basically the forces and uh what does what in the system like mathematically they had the electrical calculations of how to make the car work and they wanted to translate those calculations in the mechanics but they was missing this one component and then this university professor in UK uh came up with the inerttor. So a machine that basically saves the inertia of the system and then they were able to um balance the suspension the same way as they did with electronical stuff. Uh so this is the history of the inertther. I don't know how they used in this car particularly because uh I feel like it's still a prototype. I don't think they want to give out every single detail of it. Um, so yeah, uh, I I I I should look into that, but that's basically a complicated story short.

[00:09:31]>> Yeah, that's probably a max tangent. I just want to show you a quick clip because uh while you was talking about the clamp, I went to look on the page of the of the Facebook page of the Romanian car manufacturer, the Hydro Hyro, sorry, uh the Hyro. And uh so it it's not the type of inher it's a more rudimentary type. So uh it does still use the same principle. The principle is um the principle is that you have inertia in the suspension system uh that basically balances out your uh shocks. Um but the way they Oh my god, is this too small?

[00:10:21]I think it's too small. But basically the way they've done it is they have normal shock and then they in the same rocker they have placed some weights.

[00:10:34]So you can see I don't know if you can see that very well. It's so small.

[00:10:38]>> I can see it.

[00:10:40]>> Yeah. But basically the idea is the same. So you have inertia in the system.

[00:10:46]So basically the system wants to move.

[00:10:48]So if you have vibrations, it resists this vibration vibration system which normal like damping oil damping shocks cannot really do. Um the issue with this one though is that you you have to use a lot of weight to gain the same amount of inertia.

[00:11:09]uh also that it's it also increases like sprung mass quite a bit because like it or unsprung mass quite a bit. Uh the inerttor's idea is basically to just have the motion of the inertia without the mass uh in the same and that's why you have the ball screw and the weight but the idea is the same.

[00:11:33]The idea is to introduce um inertia in the system to counter for vibrations or like sinosoidal effects because it will always like if your car moves down the the inertia will want to keep moving the car down but then bounces up because of the spring but it balances out the the up and down like sinusal wave of the of the suspension.

[00:11:58]>> Okay, pretty cool. So you was wrong again. You was wrong. That's like the third time you've been wrong. I was I got when they said inerttor I just got excited and I started uh like >> I was like how is something screwing up in the in its drive in the shock shaft?

[00:12:12]That didn't make sense. That's why I was >> Yes, it makes it makes sense but they just didn't have it.

[00:12:19]>> Someone says you should get one and tinker with it. They should send him one.

[00:12:22]>> Yeah.

[00:12:24]>> Yeah. It's they said on their Facebook that they don't have them available yet.

[00:12:29]So this well this was kind of like a teaser.
