Ford boosted the on-road [[fuel efficiency]] of its three 2013 model year hybrids through changes in the cars' vehicle control software in an effort to improve customer satisfaction. The upgrade was offered free of charge to existing owners of these hybrids. Some of the changes include:<ref name=Upgrade>{{cite web|url=http://www.greencarreports.com/news/1085595_2013-ford-c-max-fusion-hybrids-to-be-modified-to-boost-mpg-in-real-world-use|title=2013 Ford C-Max, Fusion Hybrids To Be Modified To Boost MPG In Real-World Use |author=John Voelcker |publisher=Green Car Reports|date=2013-07-17|access-date=2013-08-16}}</ref> 
* Increasing the maximum pure electric speed from {{convert|62|to|85|mph|abbr=on}}, allowing increased use of electric-only mode on the highway
* Optimizing the use of active grille shutters to reduce aerodynamic drag under more driving and temperature conditions, including cold weather, during air conditioner use, and when the engine coolant temperature is higher
* Reducing the electric fan speed as a function of coolant temperature to minimize the fan’s energy consumption
* Shortening engine warm-up time by up to 50% to enable electric-only driving and engine shutdown at stops sooner after cold starts
* Optimizing the climate-control system to minimize use of the air-conditioning compressor and reduce the energy used in cold-weather operation
