EPA and UPS partners to unveil truck with 60 to 70 percent higher fuel economy

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.

Laboratory tests show that this technology has the potential to dramatically improve fuel economy for package delivery vehicles, 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 hydraulic hybrid propulsion system integrated with the drive axle. Hydraulic motors and hydraulic tanks are used to store energy. Like other hybrid systems, energy saved when applying the brakes is reused to help accelerate the vehicle.

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.
