I'm yet to ride/drive in a Contour with a N/A 3L, with the Zetec FD. I don't feel that the 4.06 FD proposes much of a problem with traction, or fuel efficiency. I average 23-24mpg with city/highway mix, and am around 27-28mpg on the highway. I don't think it's a matter of which FD the 3.0L should come with, but is more of a matter of preference. I'll sacrifice 1-2mpg for better acceleration, personally.
