DETROIT -- Ford Motor Co. will make software tweaks to improve the real-world fuel economy of its 2013 hybrids.
Starting this month, service departments at Ford and Lincoln dealerships will offer customers free modifications that Ford says will increase efficiency of three 2013 hybrids: the Ford Fusion Hybrid, Ford C-Max Hybrid and Lincoln MKZ Hybrid. The effort affects 77,000 vehicles. All 2014 hybrids will receive the modifications at the factory.
The changes include increasing the electric-only operating speed from 62 to 85 mph and modifying the active grille shutters to improve aerodynamic drag under a variety of driving conditions.
