Peterbilt's two most aerodynamic trucks - Model 387 and 386 - have been recognized as fuel efficient and environment friendly by the Environmental Protection Agency's SmartWay program, which 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.
"The EPA's SmartWay program is a valuable asset for fleets and customers seeking verification of the industry's leading aerodynamic solutions. Peterbilt Motors Co. 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.
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.
The premium Model 387 is designed for superior aerodynamic efficiency. The integrated cab and sleeper, rounded crown of the grille, dramatically sloped hood and fenders as well as a contoured sunvisor and roof fairing all contribute to the Model 387's fuel-efficient performance.
The Model 386 blends conventional Peterbilt styling with advanced technology and fuel-efficient aerodynamic performance. A sloped hood, swept-back fenders, a contoured bumper and sunvisor as well as optional roof fairings and side trim tabs enhance aerodynamic efficiency.
Peterbilt's complete new lineup provides customers with competitive advantages through more fuel-efficient aerodynamic designs, reduced chassis weight, improved serviceability and reliability and greater overall performance.
Peterbilt's hybrid initiatives include development of both medium- and heavy-duty vehicle platforms and for both on-highway and vocational applications, offering hybrid solutions to serve a broad range of customers to help them reduce operating expenses and to foster greater environmental stewardship.
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.
