    International announces hybrid truck assembly

    Nov 9, 2007 12:08 PM


    International Truck and Engine Corporation announced that it is the first company to enter line production of hybrid commercial trucks—the International DuraStar Hybrid, a diesel hybrid electric medium-duty truck that provides customers with improved fuel efficiency and reduced engine emissions.


    According to International, the DuraStar Hybrid diesel hybrid electric truck offers fuel savings of 30-40% on a 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.

    Man you beat me by 5 minutes.

    One other big piece of information is that this Hybrid uses Li-Ion batteries.

    They partnered with Enova for the Hybrid systems

    I thought Toyota said Li-Ion batteries were not safe. International must not care about the safety of their vehicles the way Toyota does.

    I guess these batteries must be pretty reliable if they are going to be using them on commercial trucks.

    Some more info:

    The Li-Ion battery is 2KWh but I havent been able to find out who makes the batteries.

    I just saw a report about hybrid school buses and it seems those were based on technology from Enova as well. The bus looked normal but cost 3 times as much. Seemed like a steep increase. They didn't go into any technological detail however in the video report. Seems like it was on CNN.

    You mean this story?:

    The hybrid bus gets 12mpg. That's not impressive sounding until you find out that a traditional bus gets about 6mpg!

    Yup these buses were made by International as well. But considering how much these vehicles are driven a 40% decrease in fuel consumption would make these vehicles worth the money.

    International also said that the price should come down drastically when fully produced (economics of scale).

    Same bus perhaps, but it seems the one I saw was in Pennsylvania. Seems like they said it was the 1st one made, 3rd one delivered in the country. They gave a dollar figure for what it would save them in fuel and it was quite significant but I don't remember what it was. I just searched for it and couldn't find it.

    Sure. Figure the regular model drives 100,000 miles per year and get 5 miles to the gallon. That's 20,000 gallons of fuel. A 40% increase in fuel economy moves you to 7 miles to the gallon, which reduces you down to 14,286 gallons per year.

    In three years, you saved $50,000 - which covers the added purchase price of the truck and lets you buy new batteries when you need them.

    Well, when you put it that way...... Using that math makes it look like an economy car, er, bus by comparison.

    Re: International announces hybrid truck assembly

    I still want to see a hydraulic hybrid system applied to garbage trucks and busses. This type of system wouldn't allow engine shutdown like the electrical hybrid will, but I believe they would be more far efficient at capturing most of the energy on braking and applying it to acceleration. Every time I see the garbage trucks lurch from stop to stop in my neighborhood with alternating roaring engines/screeching brakes it strikes me how great it would be if they were compressing the hell out of hydraulic fluid every stop and using it for power on every takeoff. More efficient, and quieter too!
