Peterbilt Motors Company announced the availability of the Cummins B6.7N natural gas engine in its new medium-duty Models 536 and 537.
Peterbilt’s Model 536 includes the B6.7N engine, with 200 to 240 hp and 520 to 560 pound-feet of torque available while emitting 50% lower NOx emissions than current Environmental Protection Agency (EPA) standards.

Critical information is relayed to drivers through a 7-inch digital display located in the instrument cluster, and it features a 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 Peterbilt 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 hp and 860 to 1,000 pound-feet of torque.
