Peterbilt Announces New CNG Engine for Medium-Duty Trucks

April 1, 2022

Peterbilt has announced availability of the Cummins B6.7N natural gas engine in its medium-duty Models 536 and 537.

A member of the new medium-duty lineup, the non-CDL Class 6 Model 536 is designed with a low cab entry height, excellent visibility, low NVH, and room for 3 people within the 2.1m wide cab.

Critical information is relayed to drivers through a 7-inch digital display located in the instrument cluster and featuring an intuitive digital card system fully integrated with the latest Peterbilt safety systems.

In 2007, Peterbilt introduced natural gas engines into the lineup as an option on the Model 320 and has continued to incorporate natural gas engines into the lineup.

Today, three natural gas engine platforms are available in several Peterbilt truck models.  Medium-duty trucks can be configured with the just introduced B6.7N and the L9N featuring 300 to 320 horsepower and 860 to 1,000 lb.-ft. of torque. Heavy-duty trucks including the Model 520, Model 567, and Model 579 can be outfitted with the ISX12N featuring 400 horsepower and 1,450 lb.-ft. of torque.

“Natural gas engine offerings have been part of the Peterbilt portfolio since the introduction of our first CNG-powered vehicles in 2007," said Scott Newhouse, Peterbilt chief engineer. 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.”
