Ford is working with the Center for Compact and Efficient Fluid Power and Folsom Technologies to develop a prototype F-150 light-duty pickup truck propelled by a hydraulic hybrid powertrain.


“We have the potential to reach 40 miles per gallon or higher with hydraulic power,” said Perry Li, co-deputy director of CCEFP and a mechanical engineering professor. “But we feel like we don’t give up anything versus an electric hybrid, and there are no batteries and nothing to recycle.”

 

There was a thread about the development of a hydraulic hybrid system quite a while ago. Guess this means they worked out some of the drawbacks of this system then.
