I would absolutely love to see more in-depth engine lock-ups/explosions. If someone could make a mod or add in an update an effect where when an engine is overheated and locks up there could be a chance that bits of engine block, connecting rods, or even a piston through the hood would be cool(though unlikely) pieces could be launched out from the oil pan when engines lock up along with smoke and maybe oil. This is just a suggestion I would love to see in the game.
With enough torque, the engine can be ejected from the vehicle. This sometimes happens at tractor pulls. I would love to see that level of destruction in BeamNG.drive.
