What Happened
The new Mack Granite vocational truck was designed from the ground up with sustainability as a key goal, according to chief engineer Adam White. The design and engineering teams focused on reducing CO2 emissions through engine efficiency and aerodynamics, while also selecting materials with recycled content and designing for recyclability and remanufacturability. The result is a truck that meets durability expectations while reducing environmental impact.
75%%
The wheel well splash shields use 75% recycled material with no degradation in performance or durability, and no cost increase to customers.
45%%
The entire instrument panel, including the dash, incorporates approximately 45% recycled content without compromise.
“We simulate a lot of different materials on every component to make sure we have the right material selected and that we do so as responsibly as possible from a sustainability perspective without compromising the other design attributes.”
- Reducing CO2 emissions through engine and aerodynamic improvements
- Designing for recyclability and remanufacturability of components
- Landfill-free approach across manufacturing and packaging
- Optimizing steel components for lightweight structure
Why this matters
For fleet owners, the Granite offers lower fuel costs and reduced CO2 emissions while maintaining toughness, allowing them to operate more sustainably.
