All Cars, All the Time has reported that the 2009 Ford F-150 could debut with the Hydraulic Launch Assist technology that Ford debuted with the F-350 Tonka Concept, 5 years ago. The "HLA" system utilizes a hydraulic pump and motor in combination with a high pressure accumulator, that recaptures kinetic energy while braking which is then released when accelerating to assist the engine. The system has been rumored to achieve a fuel efficiency rating of 60 miles per gallon, but that has not been confirmed. Hopefully we can gain some more details about this system and the new 2009 F-150 this January at the North American International Auto Show.
