SUVs don’t have a good reputation when it comes to fuel efficiency, but the Passport is the exception. Featuring an ECON mode button, you can switch over to this fuel-efficient setting at any time. When pressed, the engine and other non-essential functions automatically adjust to reduce fuel consumption. The Variable Cylinder Management system is also designed to switch between six and three cylinders automatically to help you save even more fuel. The Passport also features an idle stop system that shuts the engine off when the vehicle is stopped for more than two seconds, preventing excess emissions from being released into the environment.
