American Power Group Partners With Fitzgerald Glider Kits and WheelTime Network 
to Debut the First Natural Gas Dual Fuel Glider at
the Mid-America Truck Show (MATS) 
Over 70,000 Visitors Are Expected to Attend MATS on March 21-23 
LYNNFIELD, MA -- (Marketwire) -- 03/20/13 --  American Power Group
Corporation (OTCQB: APGI) announced today its subsidiary, American
Power Group, Inc. ("APG"), has partnered with Fitzgerald Glider Kits
and the WheelTime Network to offer the nation's first natural gas
dual fuel glider. The new natural gas glider makes its debut at APG's
booth at the Mid-America Truck Show in Louisville, Kentucky and will
be available beginning June 1, 2013.  
Lyle Jensen, American Power Group Corporation's President and Chief
Executive Officer, stated, "We expect the 2013 Fitzgerald/APG Dual
Fuel Glider to become one of most innovative and exciting new Class 8
vehicles on the road with 20%-30% lower net fuel costs as compared to
standard diesel engines and up to 70% lower annual maintenance
costs." Mr. Jensen added, "The introduction of a Dual Fuel Glider,
coupled with the resources provided by a Fitzgerald/WheelTime
Network/APG collaboration, could be the game-changer that accelerates
the transition of Class 8 truck fleets to natural gas as an
alternative fuel."  
Fitzgerald Glider 
 A glider kit is basically a new truck delivered
without an engine, transmission or accessory components and parts.
Fitzgerald works with Freightliner and offers a variety of new model
year Columbia and Coronado cab options. Fitzgerald assembles gliders
with rebuilt Detroit Series 60 12.7 liter engines from the WheelTime
Network and remanufactured transmissions from Eaton Fuller.  
The benefits of a glider kit are significant. The initial purchase
price is typically 25% lower than a new diesel truck. The Detroit
Series 60 12.7 liter engine, which is rated at 500hp and 1,650 lb-ft
torque, was one of the most popular engines of the 1990s, pre-dating
the addition of emissions reduction equipment required on later model
year engines. There are significantly less maintenance costs and
downtime with the Series 60 12.7 liter engine. Additionally, fuel
efficiency is typically better, with fuel mileage of up to 7 miles
per gallon. The Fitzgerald Glider comes with a three-year, 300,000
mile warranty on both the engine and transmission.  
APG Dual Fuel Add-On Option 
 By adding APG's V5000 Turbocharged
Natural Gas(TM) System to a Fitzgerald Glider, the fleet owner can
realize the additional benefits of today's favorable price spread
between diesel fuel and natural gas. Typical net annual fuel savings
when operating on APG's patented dual fuel technology range from
20%-30% compared to standard diesel operation. APG will secure "EPA
OUL Approval" for the Detroit Series 60 engine family in accordance
with the EPA Clean Alternative Fuel Vehicle and Engine Conversion
Regulations. APG will market and service the APG Dual Fuel Add-On
Option through its recently announced national WheelTime Network
Authorized Dealer Network of nearly 200 service centers, 2,800
service bays and 3,000 factory-trained technicians. 
The APG system is a cost-effective and non-invasive patented
turbocharged natural gas dual fuel conversion technology. The system
displaces a large percent of diesel with either CNG or LNG, uses
normal diesel oil, allows a vehicle to retain existing diesel
maintenance cycles, and offers a 300-800 mile dual fuel range with no
loss of power and torque, depending on the route profile and tank
configuration. No high-temperature parts or custom high-pressure fuel
injectors are required.  
With no practical design limits for engine models or horsepower, the
APG system is currently EPA-approved for 110 OUL engine families and
APG is expected to receive EPA approval for more than 100 additional
OUL and IUL engine families by the end of calendar 2013.
Additionally, the APG system offers the flexibility to return a
vehicle to 100% diesel operation at any time. At end-of-life or
vehicular rotation, the APG system and natural gas tank can be easily
removed and installed on another EPA approved engine. 
Mr. Jensen concluded, "In addition to providing fleet owners the
opportunity to convert and upgrade their existing diesel fleet to
APG's dual fuel technology, we now offer fleets a viable path to new
natural gas vehicles. We encourage them to work with Fitzgerald
Glider Kits and the WheelTime Network to purchase new gliders which
include the APG Dual Fuel Add-On Option right off the production
line. This lower cost, winning combination will provide customers
with no loss of power and torque, significant net fuel savings,
significantly lower post-install maintenance costs, lower gaseous
emissions, and it will eliminate the drivability hassles associated
with maintaining diesel exhaust fluid levels and regeneration drive
cycles. I can't think of a better venue to debut the first Dual Fuel
Glider than at the Mid-America Truck Show which has the largest Class
8 fleet owner attendance of its kind. The 2013 Fitzgerald
Freightliner Columbia Dual Fuel Day Cab will be at the American Power
Group booth (#61220 West Wing) and we look forward to a successful
product launch during the balance of 2013."
