EPA: UPS Vehicle is World’s Most Fuel Efficient

On June 21, 2006, EPA unveiled the world's first hydraulic hybrid delivery truck in Washington D.C. The EPA hybrid features a hydraulic drivetrain that replaces a conventional drivetrain and eliminates the need for a conventional transmission. By achieving 70 percent better fuel efficiency in urban driving and 40 percent lower CO2 greenhouse gas emissions, this vehicle demonstrates the highest-efficiency powertrain known. A fleet owner operating one of these high efficiency hydraulic vehicles would save up to 1,000 gallons of fuel each year. EPA estimates that over the lifespan of the vehicle the net savings based on lowered fuel consumption and lowered brake maintenance cost to be over $50,000
