Powersplit architecture.Consists of two electric machines connected to the engine and wheels through a single planetary gear set. Engine power is split between mechanical and electrical paths; E-CVT functionality is delivered through generator speed control.
It’s a simple mechanical arrangement, Gray said, noting that there are no clutches, and no torque converter. The e-CVTs functions to operate either power source in the optimum arrangement. The hybrid system offers four modes of operation:
Electric drive.
Engine drive - positive split.
Engine drive - negative split.
Regenerative braking.
Ford was able to reduce engine runtime by up to 30%. Additionally, the extra capability of the e-Drive increased the all-electric speed range up to 62 mph. All of that contributes to the overall fuel economy improvement.
Ford also redesigned the Fusion top hat with an eyer to improving aerodynamics; the 2013 Fusion Hybrid offers a 10-15% drag reduction from the outgoing product due to body design as well as the addition of features such as a full active grill.
