(Washington, D.C. - June 21, 2006) Your normal UPS delivery truck will not be the same as EPA unveils the world's most fuel-efficient and cost-effective delivery vehicle. The first of its kind, EPA and UPS partnered to develop a UPS truck that uses EPA-patented hydraulic hybrid technology that can achieve fuel efficiency by 60-70 percent in urban driving and lower greenhouse gas emissions by 40 percent.

"EPA and our partners are not just delivering packages with this UPS truck – we are delivering environmental benefits to the American people," said EPA Administrator Stephen L. Johnson. "President Bush is moving technology breakthroughs from the labs to the streets. We are doing what is good for our environment, good for our economy, and good for our nation's energy security."

Laboratory tests show that this hybrid technology has the potential to dramatically improve the fuel economy for package delivery vehicles, shuttle and transit buses, and refuse pickup. More than 1,000 gallons of fuel each year could be saved per vehicle. EPA estimates that upfront costs for the hybrid components could be recouped in fewer than three years for a typical delivery vehicle. The net savings over the vehicle's lifespan could exceed $50,000, assuming current fuel prices.

The vehicle features a full hydraulic hybrid powertrain and a unique hydraulic hybrid propulsion system integrated with the drive axle. Hydraulic motors and hydraulic tanks are used to store energy, in contrast to electric motors and batteries used in electric hybrid vehicles. Like other hybrid systems, energy saved when applying the brakes is reused to help accelerate the vehicle. Following a road tour of EPA Regional offices, the vehicle will be delivering UPS packages across Michigan this summer.

This partnership is occurring through Cooperative Research and Development Agreements, which Congress established to facilitate technology transfer of patented inventions from national laboratories to industry and the marketplace. Partners on the project are Eaton Corp., UPS, International Truck and Engine Corp., U.S. Army – National Automotive Center, and Morgan-Olson. Major technical support was provided by FEV Engine Technology Inc. and Southwest Research Institute.
