Affecting the 2013 Ford C-MAX Hybrid, Ford Fusion Hybrid, and Lincoln MKZ HybridStarting in August, Ford will tweak its 2013 hybrids when owners bring them to dealerships, making modifications that should increase real-world fuel economy (Possibly because some Ford hybrid drivers were getting lower mileage than should be expected... Whatever the reason, this is a good thing). 2014 hybrid models will have the updated settings from the factory, so no need for a dealership visit.
These calibration updates to Ford hybrid vehicles 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
"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," said Raj Nair, Ford's group vice president of Global Product Development. "Customers should see the most improvement at highway speeds, during air conditioner use and operation in colder climates."
