Peterbilt’s two most aerodynamic trucks, models 387 and 386, were 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 said its 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. 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.
Peterbilt said its 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 contribute to its fuel-efficient performance.
The model 386 blends conventional Peterbilt styling with advanced technology and fuel-efficient aerodynamic performance, the company said. A dramatically sloped hood, swept-back fenders, a contoured bumper and sunvisor as well as optional roof fairings and side trim tabs enhance aerodynamic efficiency.
Peterbilt continues development and testing vehicles equipped with advanced hybrid technologies that increase fuel efficiency, reduce emissions and improve service requirements. 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 in the testing and evaluation phase and is expected to be available in 2010, the company said.
