I wouldn’t be surprised to see a Ford Fusion Hybrid NYC Taxi (if they don’t have one already)

But I think Ford will maybe lean more toward the Transit Connect Taxi as a mass replacement for the Crown Victoria taxis. One has already been spied on NYC streets and later showed up at the auto show. The one in the link was boasted about at the New York International Auto Show.
