Peterbilt Motors Company has announced the availability of the Cummins B6.7N natural gas engine in its new medium duty truck models. Peterbilt’s new Model 536 is an ideal truck to showcase the latest Natural gas engine delivering 200-240 HP and 520-560 lb-ft torque while emitting 50% lower NOx emissions than current U.S EPA standards. The non CDL Class 6 model 536 is designed to provide drivers with a low cab entry height, excellent visibility, low NVH and room for three in the cab. Peterbilt introduced natural gas engines in 2007 as an option on its Model 320 and has continued to incorporate NG engines into its lineup. “Natural gas engine offerings have been part of the Peterbilt portfolio since the introduction of our first CNG-powered vehicles in 2007. The introduction of the B6.7N is the latest example of our environmental stewardship and ongoing commitment sustainability, extending our near-zero emissions solutions to more applications,” said Scott Newhouse, Peterbilt Chief Engineer.
