Greenwashing or no, at least Ford is moving to green up its lineup. The company recently highlighted some of the reasons to buy a new F-150, including great residual value, powerful towing capacity, lots of award from all sorts of people and, right at the end, the detail that the whole range gets an eight percent fuel mileage increase. Models with the 5.4-liter V-8 engine get 12 percent. The new SFE package helps the F-150 get fuel economy numbers of 15 mpg city and 21 mpg highway. It's an improvement, sure, but these trucks still use a lot of fuel. We're waiting for the upcoming introductions of a new 4.4L diesel V8 and a 3.5L EcoBoost V6 for even better numbers.
