Mack Trucks has announced it will offer trucks with EPA 2010 certified diesel engines later this year, joining Volvo Trucks North America (VTNA) in an early introduction of its selective catalytic reduction (SCR) technology.
With production scheduled to start this fall, Mack said it will have early availability of all models, including its vocational trucks, certified to meet the stringent new federal emissions standards that officially take effect on Jan. 1, 2010.
Mack vehicles use proprietary engines based on a global Volvo design and built alongside VTNA diesels at a Volvo Powertrain plant in Hagerstown, MD. Like all but one U.S. manufacturer, Mack has chosen SCR technology to meet the EPA’10 standards.
The EPA’s certification process for SCR engines is currently being challenged in the U.S. Circuit Court of Appeals by Navistar, the only U.S. manufacturer that says it will not employ SCR to meet the 2010 requirements. The EPA has not yet responded to the Navistar court petition, nor has the court scheduled hearings on the request. Mack and other U.S. truck makers have petitioned the court to join EPA in defending the SCR rules.
Mack’s Pinnacle series of highway tractors are built at the New River Valley plant in Dublin, Va., the same plant that builds VTNA’s trucks. The vocational Mack Granite and TerraPro series are built at Mack’s plant in Macungie, PA.
