Redesigned from the ground up, the new Granite brings industry-first safety tech to vocational trucks
Mack Trucks has redesigned its Granite vocational truck to include industry-first technologies, an all-new cab, engine and even seats that massage the driver.
The new Granite was unveiled alongside the new Mack Keystone at the Las Vegas Motor Speedway during ConExpo.
The new Granite advances Mack’s vocational truck lineup, delivering a new cab, safety technologies, enhanced driver comfort and industry-first features.
“The all-new Mack Granite embodies everything Mack stands for: legendary durability, uncompromising performance and a commitment to our customers who depend on these trucks to get the toughest jobs done,” said Mack Trucks President Stephen Roy. “We’ve completely reimagined the Granite from the ground up, bringing the same level of innovation we delivered with our Pioneer and Anthem models to the vocational market.”
New truck tech
Mack has equipped the new Granite with multiple industry-first technologies that deliver advanced protection to demanding work environments.
The available Mack Protect safety suite — the same system available on the new Mack Pioneer and Mack Anthem — includes front camera, front radar and 270-degree radar coverage with both passenger-side and driver-side radar systems. Having both left-hand and right-hand radar is a first for the vocational segment.
The Granite is also the first vocational truck to feature an electronic park brake (ePark Brake) with rollaway protection in conjunction with auto release when shifting into gear.
For improved safety, Mack also equipped the new truck with standard front and available side-curtain airbags, standard LED headlamps and fog lamps with available cornering lights.
Another first for the vocational truck segment is E911 auto-call. This feature automatically contacts emergency services when in cellular service range if an airbag deploys or the system detects a rollover or collision.
An optional proprietary camera system provides up to five camera inputs, including backup camera and downward-facing passenger-side camera for enhanced visibility of certain blind spots, which is useful for customers in urban operations. An optional digital mirror system is also available.
“We’re bringing safety technologies to the North American vocational market that have never been available before,” said Alex Lee, Mack Trucks Senior Product Manager for Vocational and Medium Duty.
“Features like the ePark Brake, 270-degree radar coverage and E911 auto-call are going to make a real difference in protecting drivers who work in some of the most challenging environments.”
The all-new Granite keeps fleets connected and running with Mack Connect telematics.
As well, the MyMack mobile app gives drivers and fleet managers convenient access to critical vehicle information from anywhere.
Granite configurations
The Mack Granite will be available in day cab and 1.1-metre sleeper configurations in both axle-forward and axle-back positions, with multiple front and rear axle ratings to handle specific customer requirements.
The truck is offered with graphite and bright trim packages, with features including LED headlights, three-piece bumper options and available sun visor. An optional hatch provides fluid access for snowplow applications.
The new Granite will be available for order in the second half of 2026. will begin in January 2027, at Mack’s Lehigh Valley Operations facility in Macungie, Pennsylvania, where all Class 8 Mack vehicles for North America and export are assembled.
Built for vocational
The Granite is equipped with the new Mack MP13 engine, delivering up to 540 hp and 1,950-foot-pounds of torque, while providing up to 3 per cent improved fuel efficiency compared with the previous engine.
The updated Mack mDRIVE automated manual transmission, available in 12, 13 and 14-speed configurations, provides 30 per cent faster shifts for improved responsiveness and shift quality.
The 13-speed features a low reduction creeper gear for improved startability on steep grades and with heavy loads. The 14-speed features a 32:1 ultra-low-speed reduction gear ideal for precision work like curb pouring and loose soil conditions. The Granite is also available with a Cummins X10 engine.
The Granite continues Mack’s legacy of durability through its legendary axles with the new MaxRide air load distributing suspension, a non-torque reactive eight-bag system that delivers superior ride quality and load management.
“Ride quality matters in vocational applications; our customers are navigating job sites, rough terrain and city streets all in the same day,” said Tim Wrinkle, Vice President, Product Owner, Vocational and Medium Duty at Mack.
“The Granite’s MaxRide air suspension delivers a smoother, more comfortable ride that helps reduce driver fatigue and keeps drivers performing at their best.”
All-new cab
The Granite features a significantly larger galvanized steel cab that is significantly larger than its predecessor, with 23 cm of additional width at the B-pillar for increased interior volume and driver comfort.
A new ImpactShield one-piece bonded curved windshield provides more impact resistance, while the shorter 2.8-metre bumper-to-back-of-cab dimension in both axle-forward and axle-back configurations simplifies bodybuilder adaptation.
The interior was designed with input from more than 30 professional drivers through an unbiased clinic at Virginia Tech, where drivers without knowledge of the Mack brand rated prototypes and provided feedback on ergonomics, placement of controls and visibility.
“Everything in this cab was designed around the driver,” said Vince Lokers, Specialist Chief Designer, Mack Trucks. “We focused on creating a driver-centric, commanding, ergonomic layout with wrap-around controls and high visibility. Features like our new steering column-mounted shifter, flat-bottom steering wheel and electric brakes were all positioned in their best ergonomic position based on direct driver feedback.”
The interior is available in three trim levels and features a new digital instrument cluster, updated materials and features carried over from the Mack Pioneer and new Anthem, and an all-new three-way adjustable steering column.
An available premium air-shock seat offers four-way lumbar support, massage and heating/ventilation functions. The new door panel design incorporates HVAC ducting that delivers heating and cooling at the driver’s shoulder, a feature borrowed from the automotive segment for enhanced comfort.
Heritage inspiration
The Granite’s exterior design was developed in parallel with the Mack Pioneer, ensuring a consistent brand across the Mack lineup.
The hood profile draws inspiration from the iconic Mack R model, with a lowered side air intake that provides increased visibility in front of the A-pillars.
“The Granite was not just an adaptation of the Pioneer,” said Lukas Yates, Expert Chief Designer for Mack Trucks.
“This is an all-new platform that was created to be applicable in both highway and vocational applications. We wanted this truck to look tough and confident going down the. road, built to be very rugged and handle anything.”
The new stainless-steel grille represents a significant advancement in quality and durability.
“This is the best grille we’ve ever done on a truck,” Yates said. “It’s very strong and rigid, with a level of quality I haven’t seen on anything else.”
A new modular bumper system addresses the complexity of vocational applications, which traditionally required more than 60 bumper variants to accommodate different tow and axle configurations.
The new design features a common centerpiece that accommodates both center and side tow configurations, with interchangeable end caps for axle-forward and axle-back positions. This innovative approach maintains all customer options while improving production efficiency. The stamped three-piece bumper integrates cornering and fog lamps in a robust, durable solution.
