The Fusion Hybrid’s EPA-estimated gas mileage leaves our foreign competition at a loss for words. It can go over 700 miles between fillups, which for the average commuter translates into a stop at the pump once a month.* And our standard I-4 engine gets 34 mpg highway, the most fuel-efficient non-hybrid mid-size sedan on the road.† Either way, driving a Fusion makes a statement. You care about the environment.
