I don't understand why a car with a v6 engine delivering 263 HP/249 Torque isn't rated for towing, not even Class I. Why is that? Is it because of the brakes? Frame? Transmission? If the Escape with a 3.0v6 or the 2.0T can be rated for up to 3500 lbs on a smaller frame, it seems to me the 3.5L Fusion should be rated for 3500 too, right?
