Trying to create a vehicle without motor that´s rolling downwards

You can use a skeletal mesh with a physics body for the vehicle’s body and 4 physics bodies (spheres) for the wheels, connected to the main body with 4 constraints. This is probably the simplest solution. You will need to assign a physics material to the wheel spheres so they roll instead of sliding. You will also need to animated the visual wheels according to the speed of the vehicle so they roll as the vehicle drives down the slope.
