Mack Trucks Expands Vocational Lineup with All-New Granite® and Keystone® at ConExpo 2026

On March 2, 2026, Mack Trucks unveiled two all-new vocational models, the Granite and Keystone, at the Las Vegas Motor Speedway, ahead of ConExpo.
Mack redesigned its vocational lineup to prioritize safety, comfort and performance, reimagining cab designs and enhancing driver experience while offering the terrain‑versatile Mack Keystone in axle-forward and axle-back options.
The all-new Mack Granite introduces industry-first safety features, including 270-degree radars, an ePark Brake, and the Mack MP13 engine delivering up to 540 HP, with faster mDRIVE transmissions.
The Keystone will be available to order in late Q3 of 2026, with Mack dealer programs like FleetPREFERRED and financing up to 100%.
The Keystone expands Mack's market reach, being offered in Latin America, while modular design and Mack Connect telematics aim to improve production efficiency and support fleet uptime, with a five-year subscription included.
