Navistar Expands Hybrid Truck Line
Navistar has announced the expansion its line of diesel electric hybrid trucks at the Hybrid Truck Users Forum in South Bend, Ind. During the forum, Navistar unveiled the International DuraStar Hybrid tractor targeted toward general freight haulers and food/beverage distributors.
The International DuraStar Hybrid is a new hybrid diesel-electric truck configuration for Navistar, which like the other trucks in the International DuraStar Hybrid line is designed to provide fuel savings from 20 to 25% 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,” said Steve Guillaume, general manager, medium truck group, Navistar. “Saving 20 to 25% in fuel costs is nearly the equivalent of paying about $2.91 for diesel at the pump versus the national average of $3.88 per gallon.”
In addition to reducing the amount of fuel used, the International DuraStar Hybrid was engineered to also reduce the amount of exhaust emissions. Overall, Navistar said, the DuraStar Hybrid emits up to 33% less hydrocarbon emissions and 35% 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 Corp. 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, Navistar said, makes the truck more efficient in standard driving, particularly in city and stop-and-go driving.
Navistar announced its entrance into the hybrid commercial truck business in November 2007. To date it said it has more than 300 International hybrid trucks and IC Bus hybrid school buses in operation around North America.Edit Module
