U.S. Air Force and Mack Trucks Partner on Refuse-Truck Hybrid Use

MACK TerraPro Low Entry garbage truck with hybrid electric power train

Mack Trucks delivered the first diesel-electric hybrid refuse truck to the U.S. Air Force Advanced Power Technology office.

The TerraPro hybrid has a rear loading refuse packer body and is equipped with a 325 hp U.S.-’07-compliant Mack MP7 engine. The hybrid electric power train includes an integrated starter, alternator and motor to regenerate energy during braking. That energy is stored as electricity in lithium ion batteries and used in place of diesel fuel to help launch the truck from stops. As a result, Mack says fuel economy is improved by 20 to 30 percent.

“The vehicles we're producing under this partnership are a key stepping stone to offering commercially viable hybrid electric vehicles to our customers,” says Dennis Slagle, Mack president and CEO.

After the Air Force reviews and tests the TerraPro hybrid, they will provide it to the City of Macon, Georgia, for continued testing in municipal waste collection. The testing is part of an agreement between the Air Force, the City of Macon and the Clean Cities Coalition of Georgia.
