Big rigs, smaller thirst
Navistar's International division, after successful trials, is ramping up production on diesel hybrid commercial trucks. Says their press release:
The International DuraStar Hybrid diesel hybrid electric truck has the proven capability to provide dramatic fuel savings from 30-40 percent on standard in-city pickup and delivery applications. The fuel efficiency can increase to more than 60 percent in utility-type applications when the engine can be shut off, but electric power still operates the vehicle. Diesel emissions are completely eliminated when the hybrid truck operates equipment (like overhead utility booms) solely on the truck's battery power, instead of allowing the engine to idle.
The Hybrid Truck Users Forum, says Navistar, calculates that annual fuel consumption for one of these vehicles will be as much as 1000 gallons less than conventional trucks of this size class. (We're not up to 18-wheelers yet with this technology, but International is working on that too.)Posted at 2:27 PM to Family Joules
