LISLE, Ill., Feb. 1, 2012 /PRNewswire/ -- Navistar, Inc. today announced its launch of a comprehensive natural gas strategy, including integrated natural gas product offerings and a strategic partnership with Clean Energy Fuels Corp. (NASDAQ: CLNE) that will provide customers with a sustainable, commercially viable solution for adding natural gas powered trucks to their fleets. "Natural gas has clearly emerged as the most realistic alternative fuel option for the trucking industry," said Dan Ustian, Navistar chairman, president and CEO. "Together, Navistar and Clean Energy have come up with a breakthrough program that offers customers a quicker payback on their investment plus added fuel costs savings from day one of operation. When combined with Navistar's industry-leading dealer network and Clean Energy's unmatched fuel distribution system, customers can be confident that bringing natural gas vehicles into their fleets makes good business sense." "We believe the deployment of new, innovative, heavy-duty natural gas engines by world-class original equipment truck manufacturers like Navistar is accelerating the transition to natural gas fuel as a game-changer for heavy-duty trucking," said Andrew J. Littlefair, Clean Energy President and CEO. "We welcome the opportunity to work with Navistar to bring the benefits of clean, cost-effective, domestically abundant natural gas fuel to the company's trucking customer base." By leveraging the company's existing integrated vehicle and powertrain platforms, Navistar will offer the broadest range of Class 6 through Class 8 CNG-/LNG-powered vehicles in the category. Clean Energy will provide a comprehensive CNG/LNG fueling solution to meet customer demands and aid in bringing new customers into the natural gas market. Navistar and Clean Energy will work closely with the company's commercial truck dealers and fleet customers on the deployment of natural gas powered trucks and a natural gas distribution support system. Together, the companies will demonstrate how a natural gas integrated vehicle offering with the right distribution and fueling solution can be integrated into a fleet's operations to reduce costs and drive efficiencies. The strategic partnership will help accelerate the adoption of natural gas technologies by making it easier for customers to invest in the new technology, including incentives aimed at neutralizing the cost difference for the diesel fuel equivalent for those who purchase at least 1,000 diesel gallon equivalents of natural gas fuel each month.
