WILLIAMSBURG, VA - Attendees of the 57th annual Electric Utility Fleet Managers Conference (EUFMC) recently had a chance to view the all-new International TerraStar Class 4/5 medium-duty truck, the Class 2-3c all-electric eStar truck, and an International DuraStar medium-duty truck equipped with a natural gas conversion powertrain.

The International TerraStar Class 4/5 commercial truck on display at EUFMC featured an Altec aluminum body, approximately 40 percent lighter than a typical steel body to help deliver significant fuel economy improvements, according to the manufacturer.

"Our customers are making 'greener' decisions when purchasing trucks," said Justin Chandler, sales manager, Altec. "We continually see an interest in the all-aluminum bodies on Altec trucks, which reduce fuel consumption and emissions, something Altec customers rank as a high priority."

The International TerraStar features the International Diamond Logic electrical system, which maximizes ease of body integration and helps deliver a number of customizable features for added convenience and safety - such as automated pre-trip inspections, headlights on with wipers, interlocks, and programmable switches.

Also on display from Navistar was the all-electric eStar truck, the first purpose-built medium-duty commercial vehicle to receive U.S. Environmental Protection Agency (EPA) certification as a clean fuel fleet vehicle as well as California Air Resources Board (CARB) certification as a zero emissions vehicle. The Class 2c-3 eStar all-electric truck has a range of 100 miles per charge, and can reduce greenhouse gas emissions by as much as 10 tons annually, according to the manufacturer. The eStar meets all Federal Motor Vehicles Safety Standards (FMVSS).

During the EUFMC, Navistar demonstrated a natural gas powered International DuraStar vehicle. The DuraStar features a conversion kit developed by Emissions Solutions Incorporated (ESI) of McKinney, Texas. ESI offers conversions ranging from 175-300 horsepower with 460-860 lb.-ft. torque and are capable of supporting both liquefied and compressed natural gas. Navistar will soon be making available for customer ordering through the Navistar Garland, Texas Truck Specialty Center facility a WorkStar model with a DT 466 engine, ESI natural gas conversion kit, and either frame mounted or back-of-cab mounted natural gas tanks.

The natural gas-powered DuraStar will be fully certified to meet 2010 emissions, according to the manufacturer.
