Peterbilt’s two most aerodynamic trucks, the Models 387 and 386, have been recognized as fuel efficient and environment friendly by the Environmental Protection Agency’s SmartWay program, the company reports. The SmartWay program establishes a comprehensive set of fuel-saving, low-emission equipment specifications for new Class 8 long-haul tractors and trailers. Peterbilt’s SmartWay compliant vehicles offer customers fuel savings of between 10 and 20 percent, lower greenhouse gas emissions, and significantly reduced NOx, particulate matter and other air pollutants, according to the manufacturer.

“The EPA’s SmartWay program is a valuable asset for fleets and customers seeking verification of the industry’s leading aerodynamic solutions. Peterbilt Motors Company is setting the pace for state-of-the-art aerodynamic designs optimized to improve air flow and fuel efficiency,” said Bill Jackson, Peterbilt general manager and PACCAR vice president. Â

Components required for the SmartWay-eligible designation include engines certified to the new 2007 emissions standards, high roof fairings, fuel tank side fairings, aerodynamic bumpers and mirrors, anti-idling options and low-rolling resistance tires.

“As customers increasingly focus on their daily operating expenses due to rising fuel costs, sales of aerodynamically-styled, fuel efficient trucks continue to climb and account for the majority of the Class 8 on-highway market today. Â As a result, Peterbilt has made significant investment in the expansion of aerodynamic products to help customers in this growing market,” said Scott Pearson, Peterbilt assistant general manager, sales and marketing.Â

Peterbilt also continues development and testing of vehicles equipped with advanced hybrid technologies that increase fuel efficiency, reduce emissions and improve service requirements. The company’s hybrid initiatives include medium- and heavy-duty vehicle platforms and for both on-highway and vocational applications.

In March, Peterbilt announced the latest of its hybrid initiatives, a hybrid electric Class 8 Model 386 configured for long-haul applications. It combines the aerodynamic efficiency of the Model 386 with a parallel-type “direct” electric hybrid system.

The heavy-duty hybrid electric Model 386, configured for on-highway use, is being developed in conjunction with Eaton and Wal-Mart Stores, Inc. It is currently in the testing and evaluation phase and is expected to be available in 2010. Wal-Mart, which operates the nation’s second largest private fleet, is supporting development by helping validate the concept and refine the final design, Peterbilt stated.
