Granite receives a complete ground-up redesign
Mack also unveiled a fully redesigned version of its Granite vocational truck, introducing a new cab, expanded safety systems, and updated powertrain options.
The new Granite incorporates Mack Protect, a safety suite that includes front radar and camera systems as well as 270-degree radar coverage with both driver-side and passenger-side detection, a configuration Mack says is a first in the vocational truck segment. Additional safety features include an electronic park brake with rollaway protection and automatic release, standard LED lighting, available side-curtain airbags, and an automatic E911 emergency call function.
The all-new cab is one of the most significant updates to the Granite. The truck’s galvanized steel cab is wider than the previous generation, providing additional interior space and improved driver ergonomics. The interior layout was developed with feedback from professional drivers, resulting in a wraparound control layout, updated digital displays, and expanded storage and device mounting options.
Like the Keystone, the Granite is available with the Mack MP13 engine delivering up to 540 horsepower and 1,950 lb.-ft. of torque, paired with an updated mDRIVE automated transmission with faster shift times. The truck can be configured with a Cummins X10 engine and Allison automatic transmission.
For vocational applications requiring specialized equipment integration, the Granite also introduces the latest version of Mack’s BodyLink electrical architecture, designed to simplify upfitting and support programmable controls for bodybuilder equipment.
Production of the new Granite is scheduled to begin in January 2027 at Mack’s Lehigh Valley Operations facility in Macungie, Pennsylvania.
Expanding Mack’s vocational platform
Together, the Keystone and Granite reflect Mack’s effort to modernize its vocational lineup while maintaining compatibility with its broader Class 8 platform. By sharing key technologies across models, Mack aims to provide consistent safety systems, driver interfaces, and connectivity features across both highway and vocational applications.
Both trucks integrate Mack Connect telematics for fleet monitoring and diagnostics and will be available through Mack’s dealer network in North America, with the Keystone also planned for select international markets.
