    Hello BeamNG Dev Team! I would like to see the chasis splitting? Like in the images below:

    that only happens on hyper/super cars with a stressed engine design. None of the current vehicles have that, it would be unrealistic to allow cars to split in half randomly for no apparent reason.

    i don't think it's usually stressed engines, but rather a multi-part chassis with a "subframe" holding all of the rear components on.

    the barstow can already have its front suframe sheared off, I wouldn't be surprised if the bolide gets such a structure in its remaster.

    oh yeah, my bad. That's how I saw it but couldn't remember if it was called subframe or not, closest thing that came to mind was stressed engines

    The older american cars in the game can do that to some extend. The Barstow, Moonhawn and the Bluebuck all have front subframes that can detach/rip off, when you crash it sideways into a tree at decent speed.

    Since all the other cars in the game either don't have a front subframe or are just too modern in general and are monocoque designs, this does not happen, and is somewhat unrealistic to expect a modern vehicle with modern design to just "split".

    That is the issue, the Covet technically has a monocoque chassis, which makes it basically almost impossible to split a car in half, at least cleanly. As I said above, the old American cars have front subframes and bodywork that can fly off.

    this can technically happen with the older muscle cars.. the front splits from the main body

    after a certain speed, and in some specific scenarios. it does not matter how your vehicle was made. ive seen any cars get split up in real life, that were not meant to be split like that.....
    but also usually those car will have compromised structure so they are weakened by rust or other things.
    the barstow splits in the front. i know its not a mid/rear engine car, but it splits.

    Every car can split (and some times even disintegrated into small pieces) no matter if it's monocoque, new or old.

    But it only happens in extremely specific scenarios and trying to simulate this could break other things.

    Well, in game I manage to stretch cars very often where they should rip apart. Anyway, if not for cars then it should be possible for big objects like bus, maybe van and long lorry trailers.

    Technically technically, it's a unibody, not a monocoque.

    It is possible for the trailers but very rare, they would rather rip into several pieces than in half

    I doubt making cars able to split would bring anything to the table considering how much effort would go into making that possible. Implementing that technology in the first place would take a while, and then I'm pretty sure every single car would have to be re-jbeamed (possibly from scratch) to support such a feature.

    Not happening in the near future IMO.

    Both words have same meaning. Mono = one, uni = one, coque = shell/body. Therefore, monocoque = oneshell/onebody.

    The "uni" in unibody doesn't mean "one" in this context. It's short for unit body, or unitary body. It means multiple distinct parts/panels attached together by welding or bonding. It's how most car bodies are made.

    A monocoque is a single piece structure, designed and manufactured as an uninterrupted structural component, usually from composites. These tend to be found in high-end super cars and racing cars... you won't find that in the family hatchback.

    So yeah, they both fall under the "structural shell" category, but in an automotive manufacturing context, they're completely different things. It might seem nit-picky, but it's relevant when considering their differences in mass and strength characteristics in a physically accurate driving simulator. You can cut out and replace a panel on a unibody, but doing so on a monocoque could seriously compromise the structure.

    Interesting, I wonder why there is no distinction between unibody and monocoque in Automation despite that being an extremely detailed game when it comes to car design

    My guess is that either the devs there are unaware of the distinction, or they are aware but don't want to add unnecessary complexity. I think there are different shell materials you can select in that game, and selecting a carbon material might imply a monocoque chassis, whereas a steel shell would imply a unibody.
