Products 54 Commercial Carrier Journal December 2008 Navistar unveiled an additional hybrid truck configuration the International DuraStar Hybrid tractor that targets general freight haulers and food/beverage distributors. International says that like the other trucks in its DuraStar Hybrid line, the latest diesel-electric hybrid Class 7 tractor has the capability to provide fuel savings from 20 to 25 percent in standard in-city pickup-and-delivery applications. Hybrid trucks are the next step in providing expanded fuel-efficiency options for customers as they face the new realities of high diesel costs and tough economic conditions, says Steve Guillaume, general manager of Navistar's medium truck group. In addition to reducing the amount of fuel used, the International DuraStar Hybrid also reduces the amount of emis-sions released into the air, according to the truck maker; overall, the DuraStar Hybrid emits up to 33 percent less hydrocarbon emissions and 35 percent less nitrogen oxide emissions versus standard diesel trucks. International says its DuraStar Hybrid trucks employ a parallel-type diesel-electric hybrid architecture that is supplied by Eaton Corp., which incorporates an electric motor/genera-tor between the output of an automated clutch and input of the automated manual transmission. The hybrid-electric system recovers energy during braking, and can add power back into the driveline during start and acceleration; International says this capability makes the truck more efficient in standard driv-ing, particularly in city and stop-and-go driving.

According to David Giroux, Peterbilt's marketing communica-tions director, the new truck is suited for applications such as bev-erage and regional-haul deliveries that require a trailer. The truck maker says its Model 335 hybrid-electric tractor utilizes Eaton's Hybrid Electric Power System with an electric motor that assists the Paccar PX-6 engine with supplemental torque for up to 25 percent fuel economy gains in local-haul applications. The system is designed to store energy during stopping through regenerative braking and then reuse it for acceleration, while also reducing fuel use, emissions and noise. Peterbilt's new class 7 Model 335 hybrid-electric tractor provides local-haul applications the benefits of a hybrid system combined with traditional Peterbilt quality, durability, perfor-mance and styling, says Bill Jackson, the truck maker's general manager and Paccar vice president. Peterbilt's expanding hybrid portfolio is evidence in our commitment to integrating hybrid solutions into fuel-efficient vehicle designs. In addition to the Eaton system, the Model 335 hybrid-electric tractor features the in-dash 7-inch Paccar proprietary Hybrid System Monitor, a display designed to provide informa-tion regarding fuel economy and battery state of charge, allow-ing the driver to modify behavior to maximize fuel economy through optimized use of the system. Peterbilt says the display also provides full diagnostic capabilities for the hybrid system, including system operating status. Peterbilt Motors Co.
