NAPA, CA. Designed for mixer, crane and other severe-duty vocational applications, the Freightliner 114SD will be available with the Cummins Westport ISX12 G heavy-duty natural gas engine as a factory-installed option starting in 2015, according to Mary Aufdemberg, director of product marketing for Freightliner Trucks. The new NG offering “will provide our vocational customers with another green option for their toughest jobs,” she said at a press conference.
Capable of operating on either compressed natural gas (CNG) or liquid natural gas (LNG), the ISX12 G will be available in ratings up to 400 hp with peak torques of 1450 lbs.-ft. In CNG configurations, the 114SD can be fitted with either 60- or 75-diesel gallon equivalent (DGE) tanks mounted behind the cab, according to Freightliner.
Designed for a variety of severe-duty applications, the 114SD is available with a range of vocational rear suspensions and frame options. It has been available with an optional 9-liter Cummins Westport ISL G natural gas since 2011.
Freightliner also currently offers natural gas engine options in its M2 112 and Cascadia 113 models.
