Mack Offers LR and TerraPro Trucks with Cummins Westport L9N Natural Gas Engine

Mack Trucks will continue offering natural-gas-powered versions of its Mack LR and TerraPro models, which are now available with the latest Cummins Westport L9N natural gas engine. The company says the engines will enable customers to meet near-zero NOx emissions levels while providing excellent performance and efficiency. Mack made the announcement at the 2017 Canadian Waste & Recycling Expo in Niagara Falls, Ontario.

“Natural gas continues to be a viable alternative fuel, providing a secure fuel supply and a steady price,” said Curtis Dorwart, Mack refuse product manager. “With the L9N, customers can take advantage of natural gas’ benefits and further reduce their environmental footprint.”

Mack says the spark-ignited L9N is capable of running on compressed natural gas (CNG), liquefied natural gas (LNG) or renewable natural gas (RNG), and it produces 320 horsepower and 1,000 lb.-ft. of torque.

Citing Cummins Westport, Mack says the L9N is among the lowest-certified NOx emission engines available in North America, producing NOx exhaust emissions that are 90% lower than the current EPA limit of 0.2 g/bhp-hr. The L9N is also certified to the EPA’s GHG 2017 emission requirements.

Mack says its LR model is built specifically to meet the challenges of refuse customers who require enhanced maneuverability, increased driver comfort and improved visibility. With both 6×4 and 4×2 configurations available, the Mack LR model works for customers with tight urban or open suburban applications, the company adds. Several control options are also available, including left-hand drive, right-hand drive, dual-drive and left-hand drive/right-hand stand-up drive. The LR model is equipped with an Allison RDS five-speed or six-speed automatic transmission.

Meanwhile, Mack says its TerraPro model enables customers to pack maximum payload into a compact footprint. Ideal for commercial front loading and rear loading applications, the TerraPro’s shorter overall length provides superior maneuverability, while its slimmer cab width allows it to navigate narrow spaces, according to the company. The TerraPro also boasts a tall forward glass area, improving safety by giving drivers more visibility.

Mack LR and TerraPro models spec’d with the Cummins Westport L9N are available for order now.
