Built at Peterbilt’s truck manufacturing facilities, these fuel efficient and emissions-compliant compressed (CNG) and liquefied natural gas (LNG) power platforms join Peterbilt’s family of SmartWay® certified on-highway vehicles and alternative fuel vehicles, forming the industry’s most comprehensive environmentally responsible lineup.

“Our natural gas Models 384, 365 and 320 demonstrate our industry leadership in developing products that will reduce harmful emissions and provide exceptional fuel efficiency,” said Bill Jackson, Peterbilt General Manager and PACCAR Vice President. “At Peterbilt, we’re engineering environmental solutions that meet customers’ reliability and durability expectations through alternative fuel and hybrid platforms. These clean powered platforms provide an environmental option for customers, without jeopardizing quality or performance.”

All Peterbilt natural gas platform vehicles are equipped with the Cummins Westport ISL-G engine which offers a 320 horsepower rating and 1,000 ft-lbs. of torque and provides an extremely efficient fuel-to-power ratio. Efficient and emissions compliant, the ISL-G natural gas engine produces horsepower and torque comparable in capability and service to the diesel engines.

Reliable service and familiar operation make a natural gas platform an ideal choice fleets, and this clean burning platform eliminates the need for exhaust aftertreatment components like DPF or SCR. Peterbilt trucks equipped with the Cummins ISL-G engines use cooled EGR to lower in-cylinder exhaust gas temperature. The ISL-G engine has a maintenance free three way catalyst (TWC) that is 95% effective in NOx conversion and is highly effective in controlling all CO2 and hydrocarbons.

The Peterbilt Model 384 powered by the Cummins Westport’s ISL-G is the industry’s cleanest burning aerodynamic platform with the power and performance to meet the needs of a wide variety of customer applications including bulk and tanker hauling, as well as in shipping ports in non-attainment areas. Additionally, the Peterbilt Model 384 has been recognized as fuel efficient and environmentally-friendly by the EPA’s SmartWay program. Peterbilt is dedicated to providing its customers the latest advances in aerodynamic design and engineering combined with the latest alternative fuel technologies.

The Peterbilt Model 365 NG is powered by the Cummins ISL-G and features innovative solutions to improve ride and handling and enhance weight distribution, as well as maximize performance and profitability without sacrificing overall efficiency. The Model 365 has a 115” BBC and is available in both set-forward and set-back axle configurations and sets the standard for quality, durability, productivity and environmental responsibility for a vocational application.

The Peterbilt Model 320 is the environmentally responsible refuse collection and solid waste transportation solution. The Model 320 low cab forward Class 8 truck features exceptional visibility and unparalleled durability. The Model 320 is equipped with the Cummins ISL-G, with CNG or LNG tanks in various sizes to provide for longer work days.

The Peterbilt Dealer Network is certified to sell, maintain and service natural gas powered vehicles at over 250 locations across the USA and Canada.
