Lightweight 3D game making software for Android with vehicle physics?


When it comes to 3d game making software that exports to Android with vehicle physics, there seem to be few alternatives to Unity. But Unity is too big so I was looking for a smaller game engine that can export to Android. I searched the internet extensively for weeks, and the only well known alternative I can find is Godot. It can export to Android and it has vehicle physics. But there is a less well known alternative called LayaBox or Layaair. it seems to be a Chinese made game engine so I don’t know if I could trust it. Has anyone any experience with Layabox? And how does it compare to Godot?
And is there any other fairly good alternative game engine with vehicle physics that can export to Android?
