This looks great.

You can move it on its on power by using the attached snippet on each wheel, if your wheels are just imported meshes and connected with constraints in a very raw way.
You turn your wheel(s) to blueprint, then either put the snippet in each of them, or use blueprint communication and reference them all from one blueprint.
What is does is apply a force to the wheel, but not at the center but with an offset from the center, here 25. The force needs to be adjusted to the wheel rotation in case of steering, going uphill etc.
That works really well and gives the most physically accurate driving to date in UE4. It is basically a torque that you apply. Building things like differential lock etc around it means basically testing if wheels are on the ground etc…there can be a lot of stuff done based on the simply snippet, because it is raw stuff and not some vehicle class etc. It is basically the first building stone to making an own vehicle class in blueprints.
Make sure your wheels have high res collision. If it is too low res, the collision mesh will make the wheel hopple at higher speeds.

Thank you,

When I have some time I am going to give this a try.

For the wheels I hope to use Soft Body Physics to simulate realistic tires when this plug-in Tendr: a real-time, volumetric, soft-body physics plug-in for UE4 - Game Development - Epic Developer Community Forums will be ready.
