Mack officially introduced the Mack Trucks Granite truck on March 2 ahead of its public debut at ConExpo-Con/Agg 2026 in Las Vegas. The reimagined heavy-duty construction vehicle represents a comprehensive redesign aimed at improving productivity, safety, and electrical architecture for demanding jobsite operations.
The new model will be available for orders in the second half of 2026, while production is scheduled to begin in January 2027 at Mack’s Lehigh Valley Operations facility in Macungie, Pennsylvania. This plant is responsible for assembling all Class 8 Mack vehicles destined for North America and export markets.
Redesigned Electrical Architecture and BodyLink IV
The truck introduces the latest generation BodyLink IV system, bringing a fully redesigned electrical architecture designed to support advanced vehicle functions and simplified diagnostics.
Enhanced Control and Diagnostics
The updated platform enables customizable logic for body integration and improved system monitoring capabilities. The vehicle also introduces an Electronic Park Brake with rollaway protection, enhancing operational safety during loading, unloading, and stationary operations.
Powertrain Options for Heavy-Duty Applications
The construction-focused truck platform is powered by the newly introduced Mack MP13 engine. This power unit delivers up to 540 horsepower and 1,950 lb-ft of torque and is paired with the Mack mDRIVE automated manual transmission available in 12-, 13-, and 14-speed configurations.
An alternative powertrain option is also available through the Cummins X10 engine. This engine produces between 350 and 450 horsepower with torque ratings ranging from 1,250 to 1,650 lb-ft, paired with an Allison automatic transmission to support varied construction and vocational operations.
Advanced Safety and Driver Visibility Systems
The available Mack Protect safety suite integrates a front-facing camera and radar technology, including 270-degree radar coverage through both passenger-side and driver-side sensors.
Additional safety and visibility enhancements include an optional multi-camera system capable of supporting up to five camera inputs, along with an optional Digital Mirror System designed to improve driver awareness and operational visibility around the vehicle.
The Mack Trucks Granite truck will be offered in both day cab and 44-inch sleeper configurations, with axle-forward and axle-back layouts available to meet the requirements of different construction and vocational applications.
