Mack Trucks display heavy-duty hybrid

Washington, D.C. – Mack Trucks, in conjunction with the U.S. Air Force, displayed a prototype mild-hybrid electric powertrain for heavy-duty trucks. The powertrain is mounted in an Air Force 6,000-gallon refueller truck, built on a Mack 6×4 chassis.

Mack is also looking into using the hybrid drive, supplied by Enova Systems, in its refuse haulers; the company is the leading manufacturer of refuse trucks in North America, with more than 70 per cent of the market. The majority of this additional development work is being performed at Volvo Powertrain North America, which supplies engines to Mack. The Volvo Group acquired Mack in 2000.
