Ford: Software Update to Improve C-Max MPG

Software Upgrade to Improve Fuel Economy of the Ford C-Max

Software Upgrade to Improve Fuel Economy of the Ford C-Max

According to Ford, owners will receive a letter in August offering a free dealer upgrade to improve fuel economy.  The software upgrade is intended to improve fuel economy in three areas: highway driving, short trips, and climate control.  Ford said the changes include:

  • Increasing the maximum pure electric speed to 85 mph from 62 mph, 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 percent 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

Raj Nair, group vice president of Global Product Development said, “Just as individual mileage can vary based on driving styles and environmental conditions, we expect fuel economy improvements will differ from customer to customer depending on individual driving habits.  Customers should see the most improvement at highway speeds, during air conditioner use and operation in colder climates.”
