Sport really feels like a little more drag and makes the car tend to follow road imperfections a bit more. It's not a Porsche, the feedback isn't super great but, for Ford's first foray into electric steering it is pretty good. I've had two of these, a '12 and a '14, both BBP so, I can't speak to how the regular car's steering feels.
