- New business-government research project to include design and development of experimental hydraulic hybrid powertrain
- Chrysler Group to focus on controls and packaging of hydraulic hybrid system adapted to current minivan
- Research efforts aim to produce running demonstration vehicle in 2012
Chrysler Group LLC and the U. S. Environmental Protection Agency (EPA) today announced a partnership to determine the possibility of adapting a hydraulic hybrid system for large passenger cars and light-duty vehicles.

"In addition to creating the jobs of the future, clean energy benefits the U.S. economy by ultimately making energy costs more affordable for consumers – especially if their dollars stay in America," Marchionne said. "Hydraulic hybrid vehicle technology is one more promising path worth pursuing in the effort to reduce our carbon footprint, and we are excited to partner with the EPA to push forward on this track."

The research project will focus on adapting the hydraulic hybrid system to a Chrysler Town & Country minivan equipped with a 2.4-liter, inline four-cylinder gasoline engine. Components of the hydraulic hybrid system include a 117 cc engine pump, a 45 cc drive electric motor and a two-speed automatic transmission. Fluid for the system will be stored in a 14.4-gallon high pressure accumulator.
The system produces power with engine torque driving a hydraulic pump that charges the high pressure accumulator of up to 5,000 p.s.i. The high-pressure accumulator delivers the pressure energy to the axle hydraulic motor, giving the vehicle power to drive the wheels. The gas engine will remain off if the accumulator charge is sufficient to drive the motor.
"In this hydraulic hybrid project, the Chrysler Group and EPA will evaluate and, hopefully, validate fuel-efficiency gains and greenhouse gas reductions," Marchionne said. "One of the aims of Chrysler Group’s integration efforts will be to meet driver expectations for smooth and quiet operation, so that Americans will want to buy and will enjoy driving vehicles with this technology."
The Chrysler Group has actively adopted fuel-saving technologies including cylinder deactivation on V-8 engines, a new MultiAir system that is being introduced on the Fiat 500 today and will introduce an eight-speed transmission in the 2011 Chrysler 300 that will be introduced later this year. Chrysler Group also will introduce 150 Ram 1500 trucks with a plug-in hybrid system in the coming months as part of a project with the U. S. Department of Transportation.
