And Promotes New LNG Option for Heavy Models 579 and 567
Peterbilt introduced two new medium-duty vehicles powered by compressed natural gas at last week’s Mid-America Trucking Show in Louisville, and said it’s making its heavy duty Model 579 and 567 trucks available with liquefied natural gas.
The medium duty CNG Models 337 and 348 are powered by the 8.9-liter Cummins Westport ISL G engine with 320 horsepower and 1,000 foot-pounds of torque.
They have been designed for maneuverability, with a 110-inch BBC (from bumper to back-of-cab) “two inches shorter than any competitive model,” according to Peterbilt chief engineer Scott Newhouse, as quoted in a release.
Agility and Quantum
CNG fuel cylinder assemblies for Peterbilt trucks are supplied by Agility Fuel Systems and Quantum.
The medium duty CNG Peterbilts are in production, the company says. They may be configured as straight trucks or tractors.
Peterbilt showed a CNG-fueled 337 with an Agility cylinder array at its MATS Booth.
The manufacturer also said at Louisville that its heavier Models 579 and 567 trucks, powered by the 11.9-liter Cummins Westport ISX12 G engine with up to 400 horsepower and 1,450 foot-pounds of torque, are being made available with LNG fuel systems.
‘Choice and Flexibility’
The new models give customers “greater choice and flexibility for their business and operation requirements,” said assistant sales and marketing GM Robert Woodall.
Production of Peterbilt’s CNG-fueled 579 and 567 began last year. Production of the LNG daycabs is slated to begin in June.
