“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.,” said Jonathan Randall, president of Mack Trucks North America, during an announcement at Waste Expo in New Orleans.
The model is expected to appeal to waste customers that want an alternative-fuel solution or that generate their own fuel, such as renewable natural gas from landfill waste.
The CNG Mack Granite truck is only available as an axle-back model. It features new, more modern fascia with an updated chrome grille and self-heating LED headlamps that Mack reports improve forward visibility by up to 29% and peripheral visibility by up to 50%. The lights’ integrated heating elements automatically sense the ambient temperature and turn 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.
Mack introduced the refreshed Mack Granite model in January at World of Concrete 2023 in Las Vegas, Nevada. For more information about the CNG Mack Granite model, visit www.macktrucks.com.
