DETROIT, March 4 /PRNewswire/ -- General Motors North American Truck Platforms (NATP), Chevrolet Motor Division and Spartan Motors, Inc. (NASDAQ-NMS: SPAR), of Charlotte, Mich., announce two separate agreements today establishing an innovative alternative in sharing resources to build and market rear diesel engine "pusher" motor home chassis beginning in the 1995 model year.  These agreements provide General Motors (NYSE: GM), currently a producer of front engine motor home chassis, with immediate access to the rear engine motor home chassis segment.  They provide Spartan Motors with additional manufacturing capacity to produce the current designs and the agreements make Chevrolet Motor Division the only full line marketer of motor home chassis products in North America.  The first agreement provides GM license to build Spartan Motors' Discovery/1K motor home chassis with rear "pusher" diesel engine at NATP's Detroit Assembly plant.  The chassis will be rebadged as a P72 model.  Many of the components of this motor home chassis are already supplied by GM including an all GM powertrain, 6.5 liter turbo charged V8 diesel engine with either a Hydramatic 4L8OE or Allison AT542 automatic transmission.  This entry-level chassis will be offered in the 16,000-pound through 18,000-pound Gross Vehicle Weight Rating (GVWR) and marketed under the Chevrolet nameplate.  The P72 model will receive the standard 36-month, 36,000-mile GM warranty and will be serviced by Chevrolet light-duty truck dealers nationwide.  Under the second agreement Spartan will build a rear diesel engine "pusher" motor home chassis, badged as a P92 model, also to be marketed under the Chevrolet nameplate.  The Spartan-built rear engine premium-level chassis will be powered by a Caterpillar 3116 L6 diesel engine (200-275 horsepower) and Allison transmissions offered at 18,000-pound to 23,000-pound GVWR.  The standard chassis warranty will be 12 month, 24,000 miles.  Warranty and service for this chassis also will be available through authorized Chevrolet dealers.  "We are pleased to reach these agreements with Spartan Motors that allow both companies to address competitive challenges.  These agreements enable GM to address the market needs and move more quickly in producing rear diesel engine 'pusher' motor home chassis, than had we waited to design and build our own versions independently," said Clifford J. Vaughan, GM vice president and group executive for North American Truck Platforms.  "We're very excited by the potential these agreements represent," said Spartan Motors President and Chief Operating Officer John E. Sztykiel.  "These two agreements should enable both companies to expand market share in the recreational vehicle (RV) business, and we feel that everyone involved will benefit:  Spartan Motors, GM and especially the RV customer, who will be getting quality chassis at competitive prices."  Detroit Assembly has produced chassis for more than 20 years.  The GM-Spartan agreements are effective for four model years (1995-1998) with an annual option to extend the agreements for one year if mutually agreeable. /CONTACT:  Linda Cook, 810-456-7252, or Mary Ann Tyler, 810-456-7254, both of GM North American Truck Platforms; or Tony Sommer of Spartan Motors, 517-543-6400/  (GM SPAR)  CO:  General Motors North American Truck Platforms; Chevrolet Motor   Division; Spartan Motors, Inc.
