not sure if the FR200 is the same as the Focus RS over in Europe but it most defiantely did come with a ATB diff, I watched the top gear(iirc) episode where it was tested and they commented about it.
It was a concept built by Ford Racing to show off the potential of the Focus platform.
They did a good job on the performance side of it, but IMO, they failed horribly with the appearance.
