LYNNFIELD, MA--(Marketwired - Sep 21, 2015) - American Power Group Corporation (OTCQB: APGI) announced today that its subsidiary, American Power Group, Inc. ("APG"), has received follow-on purchase orders from Harrison Truck Centers ("HTC") for thirty-five (35) of APG's Turbocharged Natural Gas® Dual Fuel Systems for HTC's new line of dual fuel heavy-duty and severe-duty glider kits. In collaboration with WheelTime Network's Interstate Power Systems, HTC will install APG's Dual Fuel systems and associated natural gas storage tanks at HTC's glider kit production facility in Elk Run Heights, Iowa. Deliveries are scheduled for September and October. Harrison Truck Centers is an Iowa-based, full service Freightliner/Western Star dealership and one of the industry leaders in the production of Freightliner Glider Kits.

A Freightliner Glider Kit is designed, engineered and assembled alongside new Freightliner trucks giving the prospective fleet owner everything a new truck offers except for two of the three main driveline components (engine, transmission, or rear axle). The fleet owner can either recapitalize any of the driveline components from their existing unit or specify a factory installed remanufactured engine or reman rear axle. Freightliner Glider Kits are available in day cab or sleeper units with a wide range of options at a much lower cost compared to a new diesel truck. Target markets will include heavy-haul on-highway glider kits and HTC's first severe-duty dual fuel glider kits for the oil and gas, logging, and mining industries. The addition of APG's Dual Fuel system capabilities complements HTC's existing dedicated natural gas engine product line. APG has an industry leading 474 EPA engine family approvals covering a wide range of engine models that are eligible to be installed in glider kits. 

Brian Harrison, Harrison Truck Center's President and CEO, stated, "Since our APG dual fuel product launch last spring, we have seen significant interest in the benefits of our APG dual fuel glider. This summer's field demonstrations have confirmed we now have a proven mainstream dual fuel solution to address the underserved high horsepower natural gas engine market. We have not found a natural gas engine solution above 400 horsepower other than APG's dual fuel solution that can meet the demands and power performance of heavy-haul and severe-duty vocational trucks, especially in extreme or severe operating environments." 

Lyle Jensen, American Power Group's Chief Executive Officer, commented, "This order is a for a long-time APG customer who is on track to have close to one hundred dual fuel trucks in their fleet by the end of 2016. They are a prime example of someone who has a true appreciation of the economic and environmental benefits of how APG's dual fuel solution can still deliver measurable savings and provide a competitive advantage, even in today's lower priced diesel environment. The motivation for dual fuel conversions continues to be fuel savings, normal diesel-like maintenance costs, no loss of power and torque for their drivers, and a significant engine weight savings associated with gliders over new diesel engines allowing more revenue per load to be delivered. APG is proud to be a part of this win-win solution."

Mr. Jensen added, "We will display Harrison Truck Center's severe-duty Freightliner 122SD dual fuel glider at the Natural Gas for High Horsepower Summit 2015 in Dallas, TX on October 27-29, 2015. Today, the heavy-haul trucking industry does not have a viable natural gas engine option for the 400 to 600 horsepower Class 8 trucks. As a result, we are gaining more attention in this specific niche of natural gas engines as oil and gas, logging and mining fleets discover APG's ability to pull the heavier loads while maintaining diesel-like performance."
