Both the Ford Expedition and Lincoln Navigator flex fuel vehicles round out the worst cars for the environment 2011 list. The 5.4L 8-cylinder four-wheel-drive vehicles earned a Green Score of 23 with an average fuel efficiency of 13 mpg/18 mpg city/highway. When compared to the competition, the Chevy Suburban, the Expedition looks like a good choice. However, a Green Score of 23 is not something that consumers should get excited about.
