    Mack Trucks is releasing a compressed natural gas (CNG)-powered Mack Granite model, the Volvo Group subsidiary announced this week at 2023 WasteExpo in New Orleans.

    Developed for waste customers that want an alternative-fuel solution or that generate their own 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,” said 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 new fascia design with an updated chrome grille and self-heating LED headlamps that offer brighter illumination, improving forward visibility by up to 29%, and peripheral visibility by up to 50%, according to a Mack press release. The integrated heating elements automatically sense the ambient temperature and turn on to keep ice and snow from building up in colder environments. An anti-fog coating prevents condensation in warmer, humid environments to improve visibility.
