[BUG] Very lightweight car locks up engine

Hi guys!
Awesome game, I'm really enjoying myself. However, I have a bug to report, hopefully we can get it sorted out.

So, I created a very lightweight car (around 320 Kg) in automation, but whenever I try to run it, the engine locks up, without saying why. There's no overheating, no overtorque, no anything....
Could you take a look and maybe you'll figure out what I'm doing wrong?

Also, it would be a great feature to know why the engine failed, sometimes it says why but others it doesn't.

I've uploaded the full zip with the mod.

Thanks a lot!!

i'm assuming it's too much friction and too little inertia. try swapping out your engine's jbeam with the one i've attached and see if it fixes it.

 

This worked very well. Thanks, and sorry for the late reply!
