Mack Unveils New Granite Cab for Vocational Jobsite Work

Mack Trucks has introduced the redesigned cab for its all-new Granite vocational truck, emphasizing driver comfort, ergonomics and technology designed for demanding construction and contractor applications.

The updated Granite was developed using customer input, driver clinics and engineering refinements, with Mack focusing on features intended to improve comfort and usability for operators spending long hours behind the wheel.

“Drivers are the heart of every vocational operation, and they are getting harder to find and harder to keep,” said Jonathan Randall, president, Mack Trucks North America. “With the all-new Granite, we set out to build a cab that drivers want to come back to every day. From the additional shoulder room and premium seating options to class-leading steering and ride technologies, every element of this truck reflects our commitment to the men and women behind the wheel.”

The cab redesign includes a wider interior profile and a reconfigured layout informed by an independent driver clinic conducted at Virginia Tech in Blacksburg, Virginia. More than 30 professional drivers evaluated prototypes and provided feedback on visibility, ergonomics and control placement.

Among the new features is an accessory rail mounted across the instrument panel, serving as a mounting surface for Electronic Logging Devices (ELDs) while also functioning as a grab bar for drivers entering and exiting the cab. A reinforced ELD mounting plate is also built into the dash for secondary screens and monitors.

The Granite now features a 12-inch Mack CoPilot digital instrument display, paired with an optional nine-inch infotainment screen. Mack said the interface was developed to combine digital tools with familiar controls to improve operator usability.

Additional interior updates include a flat-bottom steering wheel for added legroom and steering wheel-mounted controls for navigation, cruise control, lighting and infotainment systems. Stalk-mounted Mack mDRIVE Automated Manual Transmission controls are designed to simplify shifting while allowing drivers to keep their hands on the wheel.

The truck also includes USB-C ports, 12-volt outlets and an available wireless charging system to support multiple devices used throughout the workday.

To improve operator comfort during long shifts, Mack redesigned the seat structure to provide added support for the legs, back and lumbar region. A premium air-shock seat option includes heating, cooling and massage functions.

“Vocational drivers are running their trucks through some of the toughest conditions on the road, and the cab is where they spend their day,” said Tim Wrinkle, vice president, product owner, vocational and medium duty at Mack Trucks. “With the all-new Granite, we focused on the details that matter most to drivers – the room to move, the controls in the right place, the seat that supports them through a long shift – and surrounded that environment with the steering, suspension and ride technologies that keep them comfortable and productive from the first job to the last.”

Mack also expanded availability of its Mack Command Steer system to both axle-forward and axle-back Granite configurations. The system is designed to reduce steering effort by up to 85%, supporting maneuverability across construction and vocational jobsites.

The new MaxRide Air rear suspension system is designed to improve ride stability and reduce driver fatigue through an electronically controlled air suspension setup.

The Granite also includes durability-focused interior upgrades, including aluminum door handles, reinforced storage pockets and heavy-duty fabrics. Mack said the truck’s standard Mack ImpactShield windshield with Corning Fusion5 Glass is designed to improve resistance to impacts and scratches.

The all-new Mack Granite is expected to be available for order later in 2026, with production beginning in January 2027 in Macungie, Pennsylvania.
