published: June 11, 2009

VANCOUVER, BC– Cummins Westport Inc. (CWI), a leading provider of high-performance, alternative fuel engines for the global market, announced today that Daimler Trucks North America will offer the ISL G Natural Gas (NG) engine in the Freightliner Business Class® M2 112 truck in a total of six LNG and CNG tractor/truck configurations. The rollout begins today with an LNG tractor for port and regional haul applications. The Cummins Westport ISL G, an 8.9 litre stoichiometric cooled-exhaust gas recirculation (EGR) engine, meets 2010 EPA emissions today, reduces greenhouse gas emissions and offers top-level performance and efficiency.

Later in 2009, a CNG version of the tractor is expected to be offered, followed by CNG single axle tractor, 4X2 and 6X2 truck, and vocational configurations. It is expected that the entire natural gas offering will be available by the end of 2010.

“Introducing a factory designed and engineered Business Class® M2 112 with natural gas adds to Daimler Trucks’ “Shaping Future Transportation” initiative while we continue to provide our customers a hard-working truck with added economic and environmental benefits,” noted Melissa Claussen, Director of Marketing, Freightliner Trucks. 

Roe East, President of Cummins Westport, added, “This is a great opportunity for CWI to partner with Freightliner, one of North America's market-leading truck manufacturers. By launching the Cummins Westport ISL G in the M2 112 tractor, Freightliner will be able to provide customers with clean, economic natural gas power for a wide range of applications. By the end of 2010, Freightliner Trucks expects to have a complete CWI-powered lineup with configuration options for over 90% of truck applications in North America.
