American Power Group Expands Industry Leadership Role With Third Intermediate Useful Life Submission Approval From EPA Within Last 90 Days

LYNNFIELD, MA--(Marketwired - Mar 18, 2015) - American Power Group Corporation (OTCQB: APGI) announced today that its subsidiary, American Power Group, Inc. ("APG"), has received online notification from the U.S. Environmental Protection Agency ("EPA") that its recent Clean Alternative Fuel Vehicle and Engine Conversion Submission has been approved for the following additional Intermediate Useful Life ("IUL") engines:

The submission utilized APG's V5000 Dual Fuel Turbocharged Natural Gas® technology which is required to meet specific design, componentry and emission compliance criteria per the EPA Final Rule 40CFR Parts 85 and 86. Eight Detroit Diesel DD 13 engine families became APG's third IUL approval covering Selective Catalyst Reduction ("SCR") engine technology which meets or exceeds the current 2010 EPA OEM certified engine emission standards. APG leads the industry with 473 OUL and IUL approvals covering six of the top OEM engine platforms including 17 IUL approvals for 2012-2010 OEM engine families (Detroit Diesel DD15/DD13 and Mack/Volvo D13) with SCR engine technology.

Lyle Jensen, American Power Group Corporation's President and Chief Executive Officer stated, "We are especially pleased to add the 2012-2010 Detroit Diesel DD13 family with SCR engine technology to our list of EPA approved engines. The DD13 engine offers an optimal blend of performance and efficiency that is specifically designed for the less-than-truck-load (LTL), regional distribution and vocational applications. Logistic traffic patterns are beginning to change to more of a hub and spoke route versus the historical long haul routes. The DD13 engine, in an APG Dual Fuel configuration, addresses this new traffic pattern and opens up an expanded natural gas vehicular market for APG in the 350HP to 470HP range." 

Mr. Jensen added, "IUL engine approvals including those with SCR technology are critical for us to address the needs of the larger national and regional fleet operators who rotate their vehicles every four to five years. Since our first IUL engine family approval in December 2014, we have several notable Top 100 Fleets, as ranked by Transport Topics, evaluating our new Natural Gas Turbocharged® Dual Fuel Technology. We have secured a list from R.L. Polk of approximately 4,300 U.S. registered DD13 owners representing over 30,000 trucks for engine production years 2013-2010. This target list will be marketed through our natural gas supply partners and our WheelTime Certified Dealer Network who have been Detroit Diesel parts and service dealers for years and have established business relationships with many of the identified fleet owners. We estimate there are 600,000 - 700,000 Class 8 trucks that fall into the total eligible IUL designation."

Mr. Jensen concluded, "One of the most important attributes of APG's non-invasive Dual Fuel System for truck owners who rotate their fleet every four to five years is the ability to transfer the APG system and natural gas tank to their next vehicle at the time of rotation. This allows the fleet owner to realize maximum end-of-life value for the truck being rotated out as a clean burning diesel truck. For a few thousand dollars, the next truck in rotation can be up-fitted with the existing APG Dual Fuel System and natural gas tank and APG's read-only electronic control module will be re-programmed to the next applicable EPA approved engine model. APG's system and third-party natural gas tanks are rated for a 15 to 20 year operating life that can generate estimated lifetime fuel savings measured in the hundreds of thousands of dollars or multiples of the total dual fuel investment. Our recent EPA approvals with SCR engine technology will open up more opportunities for us and underscores APG Dual Fuel technology as a valuable long-term cost reduction asset."
