Navistar is expanding its line of diesel electric hybrid trucks with the addition of the International DuraStar Hybrid tractor, targeted toward general freight haulers and food/beverage distributors.

This diesel electric hybrid Class 7 tractor offers fuel savings from 20-25 percent on a standard in-city pickup and delivery applications. The International DuraStar Hybrid also reduces the amount of emissions released into the air. Overall, the DuraStar Hybrid emits up to 33 percent less hydrocarbon emissions and 35 percent less nitrogen oxide emissions versus standard diesel trucks.

International DuraStar Hybrid trucks employ a parallel-type, diesel-electric hybrid architecture that is supplied by Eaton. It incorporates an electric motor/generator 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. This capability makes the truck more efficient in standard driving, particularly in city and stop-and-go driving.
