Mack Trucks Expands Powertrain Options with Lighter-Weight Configuration for Waste Industry

LAS VEGAS, NV (May 7, 2025) – Mack Trucks announced today the expansion of its Mack® Granite® Compressed Natural Gas (CNG) model line with the addition of the Allison 3000 Series transmission option paired with the Cummins L9N natural gas engine, providing waste customers with a cost-effective alternative when maximum gross vehicle weight ratings aren't required.

“This expanded powertrain option gives our customers more flexibility to optimize their trucks specifically for lighter duty waste applications,” said Jonathan Randall, president, Mack Trucks North America. “By offering the Allison 3000 paired with the L9N, we're delivering a solution that reduces acquisition costs while maintaining the reliability and performance Mack customers expect, particularly for light-duty roll-off applications where a higher GVWR isn't necessary.”

The Allison 3000 Series transmission, when paired with the Cummins L9N, provides a lighter-weight, lower-cost option compared to the Allison 4500 configuration. This pairing is ideal for operators looking to balance performance with cost-efficiency in applications that don't require the higher gross vehicle weight rating.

The Cummins L9N natural gas engine delivers 320 horsepower and 1,000 ft.-lb. of torque while offering reduced emissions through its CNG power system. The engine is certified to the California Air Resources Board and EPA's Optional Low NOx emissions standard.

Mack's comprehensive lineup for the waste industry at WasteExpo will include a Mack TerraPro® Daycab, a Mack MD6 battery-electric vehicle (BEV), and a Mack Granite® Compressed Natural Gas (CNG) with Allison 4500 RDS transmission with 6th Gen Controls. Additionally, Mack will feature an LR Electric in the ride-and-drive event from 10:30 a.m. to 3 p.m. on May 7 at the West Hall Diamond Lot of the Las Vegas Convention Center.
