Mack debuts compressed natural gas heavy-duty truck at WasteExpo 2023

Mack Trucks has debuted a compressed natural gas (CNG)-powered Mack Granite model at WasteExpo 2023. The Mack Granite CNG was developed as an alternative-fuel option for the waste management segment or for those who create their own CNG fuel.

The Mack Granite CNG model features a 320-horsepower Cummins L9N engine matched with an Allison 4500 fully automatic 6-speed transmission. 

"Mack Trucks is known for producing customized trucks that meet the exacting needs of our customers," says Jonathan Randall, president of Mack Trucks North America. "The CNG Granite model is a perfect example of our capabilities. Our waste customers asked for a CNG-powered Granite, and working with Cummins, we delivered a solution that offers the durability, reliability and comfort for which Mack Trucks is known."

The CNG Mack Granite truck is only available as an axle-back model and features a modern design with an updated chrome grille and self-heating LED headlamps that offer brighter illumination. Mack introduced the refreshed Mack Granite model at World of Concrete 2023. The new grille and air intakes modernize the look of the Granite, and the choice of two grille treatments offers another way to customize vehicles.

Self-heating LED headlights round out the updates and add to the suite of safety features already on previous Mack Granite models. The integrated heating elements automatically sense the ambient temperature and turn it on to keep ice and snow from building up in colder environments and an anti-fog coating prevents condensation in warmer, humid environments to improve visibility.
