Ford is currently working on a bran new hybrid powertrain for the ever-popular Ford Fusion, as well as the Ford C-Max concept vehicle. The engine of this hybrid will gain in miles per gallon output, while also being effectively cheaper. How is that even possible?
How exactly does Ford achieve this? Well, first off they don't use one hybrid engine, they use two!
Ford's hybrid system actually utilizes two electric motors -- one as a generator, the other one to drive the car. Linked to the gas engine is a gearset, called a "torque-split device." This acts as a continuously variable transmission (CVT) and diverts power between the gas engine and the electric motor.
Rumors also suggest this motor could be implemented as soon as next year, though it is more likely Ford will test it for longer, having it in production by 2014 - 2015.
