Peterbilt, Eaton, & Wal-Mart Partner on Hybrid-Electric Model 386
– Peterbilt Motors Co. and Eaton Corp. have collaborated to produce an aerodynamic, heavy-duty vehicle with hybrid capabilities, with Wal-Mart Stores Inc. supporting development of the technology, according to the Web site www.thetrucker.com. Wal-Mart is helping to validate the concept and refine the final design.
Peterbilt and Eaton previously have partnered to develop hybrid-electric Class 6-7 vehicle platforms and Class 8 hybrid hydraulic vehicles. With a successful test and evaluation program, the heavy-duty hybrid electric power system will be available in 2009.
Wal-Mart previously had unveiled its “Sustainability 360” program to “promote environmental stewardship” among its customers. Wal-Mart expects the hybrid version of the Peterbilt 386, which the fleet already operates, to increase fleet efficiency by 25 percent over the next few years.
During third-party testing, the Eaton Hybrid Power System has achieved a five to seven percent fuel savings over non-hybrid models.
