Two issues left about WHEELS: low torque and unlimited suspension travel

    A month ago I created a feedback topic in the support forum about wheels:
    https://support.keenswh.com/spaceen...r-is-weak-and-power-consumption-2kw-is-a-joke

    Now I'm happy to see that wheel power usage is now much higher in the public beta build. But wheel torque is still not enough to haul heavy cargo.

    Firstly, in my opinion wheels in Space Engineers are the efficient way of transportation in high gravity environment. Because, flying with millions of kg cargo would require an expensive ship and power/fuel. So I expect that wheels should fit in this role.

    I use my large block 8-wheeled truck to test:
    - Empty mass is 350 tons.
    - Has one large cargo container.
    - Total mass is 4000 tons when its filled with ore in realistic settings.

    Eight 3x3 wheels can't even produce enough power to move it on semi-flat ground. Shouldn't 8 wheels capable of moving 1 large cargo container full of ore?

    The second issue: Unlimited suspension travel.

    There has to be a minimum suspension travel limit that can be adjustable or not. Because currently wheel suspension has 100% freedom and when one wheel hits a small bump that is high enough to move wheel suspension upside 100%, wheel block gets destroyed along with several nearby blocks. To prevent this I have to use very hard suspension strenght that's not good for vehicles and makes suspension useless.

    Wheels were optimized for race cars. Keen has trouble understanding the needs of large builds. Before 1.187 your wheels would have worked fine. Apparently there was a decision made somewhere that the game would attract more players if they could easily build race cars. In the process they made building larger wheeled mining equipment more unlikely than ever. Suspensions can no longer deal with heavy loads the way they used to. Normally I would suggest switching to the 5x5 suspension but the larger size seems to have even less torque.

    Two things you could do:
    • Get rid of the armor shell. It's unnecessary weight unless you are transporting in a war zone or something. I make cargo containers part of the frame.
    • Double the suspension. Sixteen 3x3 wheel suspensions ought to get you moving. Just don't try to go fast.
    Have fun :)

    I will have to retest the wheels I havent in a while. Last time I had my cargo truck loaded full (Similar to yours @Thales M.), I had no issues moving tons of my cargo...maybe it wasnt as heavy as yours but pretty sure it was.
