The Pete Store Delivers Class 8 Peterbilt Hybrid Truck to Wal-Mart in Partnership with Eaton and Peterbilt Motors

The Pete Store, Inc. announced the delivery of what it claims is the industry’s first Class 8 hybrid truck to Wal-Mart Stores, Inc. The Peterbilt Model 386 Hybrid is the first of its kind and will be an addition to Wal-Mart’s fleet of over 230 Peterbilts they currently have in service.

"The implementation of Hybrid trucks is an encouraging step towards environmental sustainability and the reduction of emissions throughout the industry," says John Arscott, President of The Pete Store, Inc. "Wal-Mart is proving to be a leader in this arena, and The Pete Store is pleased to play a part in such a landmark event within the transportation industry."

The 386 Hybrid truck is part of a comprehensive commitment by Wal-Mart called "Sustainability 360" which promotes innovations to increase environmental conscientiousness throughout their organization, including vendors and customers. Wal-Mart has demonstrated a commitment to becoming a leader in the transportation industry by setting a goal of improving overall fleet efficiency by 25%.

Wal-Mart’s Senior Vice President of Transportation, Tim Yatsko, commented on their commitment to environmental innovation: "Wal-Mart is careful to consider the civic and environmental impact its operations have in the communities it serves around the world. We are continually looking for new, innovative ways to improve the fuel economy and reduce the emissions of our fleet. We currently operate the Peterbilt Model 386, and we anticipate that the hybrid version will help us move toward our goal to increase our fleet efficiency by 25% over the next few years."

The Hybrid technology utilized on this truck is designed by Eaton Corp.. The system (called Eaton Hybrid Power System) retains energy generated by the engine, which would normally be lost during braking, and stores it in batteries for later use. That electricity is then sent through the motor/generator and blended with engine torque to improve vehicle performance, operate the engine in a more fuel-efficient range for a given speed and/or operate only with electric power in certain situations. This process has been shown to increase driving efficiency by 5-7%. The system’s batteries even power the heating, air conditioning, and electrical system when the engine is turned off. The improved miles per gallon, combined with the reduction of idle time, could result in approximately $9,000 in annual fuel savings based on an average cost of $2.50 per gallon.
