The wait is officially over.
Mack Trucks has unveiled the All-New Mack® Granite®, marking a major milestone for the vocational truck market. Alongside it, Mack also introduced the all-new Mack® Keystone™, reinforcing its commitment to delivering the toughest trucks and smartest solutions in the industry.
At McMahon Truck Centers, we’re proud to bring this next generation of vocational performance directly to our customers.
If you operate in construction, dump, concrete, municipal, waste, or other heavy vocational applications, this launch is one you need to know about.
Mike McMahon, CEO and Co-Owner of McMahon Truck Centers, puts it best:
“Mack Trucks has once again delivered a new standard for vocational trucking, with uncompromising durability and premium comfort so our customers can continue to dominate their jobsites.”
A Major Step Forward for Vocational Trucks
The new Granite is more than a refresh; it’s a complete redesign from the ground up.
Mack took everything operators valued about the legacy Granite and rebuilt it with a focus on durability, safety, performance, and driver experience.
Key upgrades include:
- An all-new, larger galvanized steel cab
- Industry-first safety innovations
- More power and improved fuel efficiency
- Advanced driver-focused ergonomics
- Smarter bodybuilder integration
- Enhanced connectivity and uptime solutions
This launch represents Mack doubling down on the vocational segment, and that aligns perfectly with the work our customers tackle every day.
Safety That Changes the Game
Safety is one of the biggest advancements in the new Granite platform.
The available Mack Protect safety suite introduces technology that has rarely been seen in vocational trucks before, including:
- Front radar and camera systems
- 270-degree radar coverage with both driver-side and passenger-side radar
- Electronic Park Brake with rollaway protection and auto release
- Standard E911 auto-call in the event of a collision or rollover
- Standard LED headlamps and fog lamps
- Optional Digital Mirror System and multi-camera visibility
For contractors operating on tight urban jobsites, municipalities working in busy traffic environments, or fleets prioritizing driver protection, these innovations provide meaningful real-world safety advantages.
More Power. Better Performance. Built to Work.
Under the hood, the new Granite features the Mack MP®13 engine, delivering:
- Up to 540 horsepower
- Up to 1,950 lb-ft of torque
- Up to 3% improved fuel efficiency
The updated mDRIVE™ automated manual transmission is available in 12, 13, and 14-speed configurations, offering 30% faster shifts and specialized gearing designed for heavy loads, steep grades, and precision jobsite applications.
Paired with Mack’s proprietary MaxRide air suspension, drivers benefit from a smoother ride whether operating on rough terrain or city streets.
The result is a truck that delivers serious jobsite performance without sacrificing efficiency or control.
Built for Customization and Connectivity
Vocational trucks demand flexibility, and the new Granite is built with that in mind.
The BodyLink IV electrical architecture enables greater customization, automation, and advanced diagnostics. This simplifies body integrations for applications such as:
- Dump trucks
- Concrete mixers
- Snowplows
- Utility and service trucks
Combined with Mack Connect telematics and over-the-air updates, fleets gain better visibility into vehicle performance while reducing downtime and maintenance surprises.
An All-New Cab Designed Around the Driver
Driver input played a major role in shaping the new Granite. More than 30 professional drivers evaluated early prototypes, helping engineers refine the final design.
The result is a cab that prioritizes comfort, visibility, and usability.
Key features include:
- Nine inches of added width at the B-pillar
- New digital instrument cluster
- Steering column-mounted shifter
- Premium seating with lumbar, heat, ventilation, and massage options
- Improved HVAC with shoulder-level airflow
- Integrated device mounting and charging solutions
In today’s competitive labor market, driver comfort isn’t a luxury—it’s a strategic advantage. The new Granite helps fleets recruit, retain, and support drivers better than ever.
Granite and Keystone: A New Era for Mack Vocational

Sales tools, digital build-and-price resources, online support materials, and training programs are already being rolled out to ensure consistent and informed customer experience across the Mack dealer network.
