Ford's been slowly but surely tweaking its MyFord Touch interface for months now, and the latest stroke of genius to come across will surely light up the faces of treehuggers. In an effort to provide more routing options to drivers, the automaker is showcasing its new Eco-Route function in the 2011 Edge, which may or may not cause velitation with the good folks over at Garmin's similarly titled ecoRoute project. At any rate, the new addition allows motorists to choose between the fastest route, shortest (distance) route or most fuel efficient route, and it places the estimated time of travel for each within eyesight. We're guessing that most of you would simply select the method that requires the smallest investment of time, but those with nothing but may enjoy the new option. And somehow, somewhere, Mother Earth is blowing you a carbon-free kiss. Check out a brief demonstration video after the break.
