The Ka and 500 will be built by Fiat on the same assembly line in Poland and use the same lineup of engines. The spy photos of the Ka show some visible body sculpting indicating that the Ka will also feature Ford's kinetic design. With that six month lag time we can probably expect the Ka to arrive in time for Geneva next March. Unfortunately, unlike the Verve/Fiesta, we won't be getting the Ka stateside.
