Cylinder deactivation allows the engine to shut down some of its cylinders during light-load operation for greater fuel efficiency. Over the last ten years, less than three percent of new cars have had this technology. A larger share of light trucks, which have hauling and towing requirements, have used cylinder deactivation as a means to provide a powerful engine when needed and better fuel economy when power is not necessary. In 2015, 27.4% of new light trucks used cylinder deactivation.
