WASHINGTON- The U.S. Department of Energy (DOE) has selected nine projects totaling more than $187 million to improve fuel efficiency for heavy-duty trucks and passenger vehicles. 

The funding includes more than $100 million from the American Recovery and Reinvestment Act, and with a private cost share of 50 percent, will support nearly $375 million in total research, development, and demonstration projects across the country. 

"Improving the efficiency of our vehicles is critical to reducing America's dependence on foreign oil and addressing climate change," said DOE Secretary Chu.  "[These] awards will help demonstrate the potential benefits for long-haul trucks and passenger vehicles and will play an important role in building a more sustainable transportation system for the country."

Three projects will focus on cost-effective measures to improve the efficiency of Class 8 long-haul freight trucks by 50 percent. These projects will receive more than $115 million in funding to develop and demonstrate systems-level fuel efficiency technologies by 2015, including improved aerodynamics, reducing engine idling technologies, waste heat recovery to increase engine efficiency, advanced combustion techniques, and powertrain hybridization. 

The remaining six projects totaling more than $71 million will support efforts to increase the fuel economy for passenger vehicle engines and powertrain systems.  The goal is to develop engine technologies that will improve the fuel economy of passenger vehicles by 25-40 percent by 2015 using an engine-only approach.
