This is more of a feature request than a bug. From a UDN customer.

The output from the simulation to the game thread does not include the force that has been applied at each wheel. It would be preferable if this information was also provided for users.

That would be the lateral and longitudinal forces applied at the wheels, provided to BP via the GetWheelState and accompanying struct breakout function.

Steps to Reproduce

Open the vehicle template or Physics sandbox (Sandbox\Physics\Sample).

Find a vehicle blueprint and try to access the wheel information by blueprint.

There is no lateral or longitudinal force information in the breakout.
