Tradeshow

WOOD DALE, Ill., Nov. 27, 2012 (GLOBE NEWSWIRE) -- Power Solutions
International, Inc. ("PSI") (OTCBB:PSIX) and Spartan Motors, Inc.
(Nasdaq:SPAR) announced today the launch of a new Class A Front Engine Gas
(FEG) concept chassis featuring PSI's newly designed 8.8-liter engine. The new
chassis, code named the Extol, is designed to meet increased demand in the RV
market for greater power performance and for gas powered engines. Both
companies will be showcasing these products at the RVIA National RV Trade
Show, which takes place November 27–29 in Louisville, Kentucky.

"PSI is excited about presenting our newly developed on-highway applications
through this collaboration with Spartan Chassis, a leader in the specialty
vehicle category," said Jeremy Lessaris, Director of Marketing at PSI.

Recreational vehicle OEMs have been frustrated with their engine options,
which until now have been underpowered. Because of the considerable weight,
RVs require significant torque for pickup and to avoid chugging or spitting on
hills. As a result, power compromises are problematic.

Powered by a PSI 8.8-liter engine that provides 430 HP and 512 lb.-ft of
torque (@ 3400 RPM), the Extol chassis offers the power performance that
end-users seek in a package developed to capitalize on the growth of smaller
Class A recreational vehicles (22K to 28K GVWR). The newly designed and
engineered engine offers 20% across-the-board improvements in power and 15%
better fuel-efficiency over its predecessor, General Motors 8.1-liter.

The Extol also provides superior handling and superior ride quality, achieved
through Spartan's proprietary suspension and new Compression Fluid Strut.
Spartan Chassis has been known for decades as a leader in the Class A diesel
market. This Extol concept chassis is an excellent brand extension which
should expand our product portfolio and fill what we perceive as a gap in the
RV chassis market," said Tom Gorman, Chief Operating Officer of Spartan
Motors. "This new chassis development illustrates both our long-term
commitment to the RV business and, more importantly, our interest to
continually find new business growth opportunities for our OEM partners in the
RV industry."

PSI's high-performance 8.8-liter "big block" replacement was launched at the
2011 RVIA Expo. The new engine is capable of fulfilling power, efficiency,
emissions and fuel-flexibility needs across a wide range of applications
beyond RVs, including school buses, waste-hauling trucks and light-duty uses.
The heavy-duty, durable block includes the following design features:

  *A significantly stronger crankcase and a forged and induction hardened
    crankshaft that enable delivery of 1,000 ft-lb of torque.
  *An intake manifold that incorporates a tuned, long-runner to increase
    torque
  *High-flow, fast-burn cylinder heads that ensure a full burn to reduce
    emissions

Power Solutions International is presenting its 6.0-liter and 8.8-liter
engines in booth number 248 at the RVIA National RV Trade Show in the Kentucky
Expo Center, November 27–29. The Spartan Chassis display is located in booth
number 1526.
