PETE FUEL EFFICIENCY PACKAGE
The improved aerodynamics of Peterbilt's new traditional truck models – the Model 389 and Model 388 – can be further enhanced with an optional Fuel Efficiency Package.
The new proprietary Fuel Efficiency Package can improve fuel consumption through aerodynamically enhanced exterior components that include a new contoured roof fairing, oval-shaped cab-mounted exhaust, aerodynamic air cleaners, streamlined tool and battery boxes and contoured bumper and underbody fairing.
The Fuel Efficiency Package complements the improved aerodynamics engineered into the new Model 389 and Model 388. The new traditional truck models, available in 2007, feature standard aero improvements through redesigned hoods, headlamps, side mirrors, hood ornament and crown and grille.
A new contoured sunvisor works with a new proprietary roof fairing to smoothly direct air flow over the cab and sleeper roof and across the trailer. This feature alone can improve fuel efficiency by nearly 10 percent versus trucks with no roof fairing, according to Peterbilt Chief Engineer Landon Sproull.
The outer and lower edges of the new proprietary bumper have been rounded to reduce wind resistance while still maintaining a bold appearance. Aerodynamic performance is further enhanced with the addition of an underbody fairing that improves air flow under the vehicle and through the radiator. Restyled fender supports also feature rounded edges to better direct air flow over the fenders.
The new 15-inch stainless steel air cleaners include a trim panel to block air from going between them and the cab. A mounted trailing tab redirects air away from the side of the cab and sleeper.
Oval-shaped, cab-mounted exhaust stacks provide a unique styling characteristic while reducing aerodynamic drag and providing a smoother flow of air from top to bottom.
Completing the Fuel Efficiency Package are new streamlined tool and battery boxes. A contoured fairing on the front of the boxes softens the surface and directs air flow around the battery and tool boxes.
The Fuel Efficiency Package will be available in early 2007.
