The 2026 Chevrolet Colorado ZR2 Bison represents the pinnacle of mid-size off-road capability, merging Chevrolet’s performance engineering with American Expedition Vehicles (AEV) hardware. This truck is not just an appearance package; it is a factory-backed rock crawler equipped with hydraulic bump stops, locking differentials, and extensive underbody protection designed to conquer the toughest terrain straight from the dealership floor.

Performance – High-Output Torque
A massive 430 lb-ft of torque defines the character of the 2.7L TurboMax engine, delivering diesel-like grunt for crawling over obstacles. Tuned specifically for the ZR2 Bison, this powertrain ensures that power is available low in the rev range, which is critical for controlled low-speed off-roading. The 8-speed automatic transmission includes unique shift mapping in “Baja Mode” to hold gears longer during high-speed desert runs.
Off-Road Capability – AEV Hardware
Boron steel skid plates cover the radiator, steering gear, transmission, transfer case, and fuel tank, offering armor that is significantly stronger than standard stamped steel. The Bison rides on 35-inch mud-terrain tires wrapped around beadlock-capable wheels, providing massive footprint and traction. Multimatic DSSV (Dynamic Suspensions Spool Valve) dampers feature position-sensitive damping that absorbs high-speed impacts while preventing bottoming out on jumps.
Design – Rugged and Functional
Steel bumpers distinguish the Bison, with the front bumper featuring winch compatibility and removable end caps for improved approach angles. The aggressive stance is widened to accommodate the massive tires, necessitating unique fender flares that protect the bodywork from debris. Visually, the “Flow Tie” grille emblem allows for increased airflow to cool the engine during strenuous low-speed crawls in hot environments.
Technology – Terrain Intelligence
Up to 10 camera views are available, including an underbody camera with a washing system to help drivers spot obstacles beneath the truck without a spotter. The 11.3-inch infotainment screen houses the “Off-Road Performance Display,” which provides real-time data on pitch, roll, tire pressure, and GPS coordinates. Google Built-In ensures that navigation maps are always up to date, even when venturing far off the grid.
Versatility – Bed and Cargo
An integrated tailgate storage system offers a watertight, lockable compartment within the tailgate itself, perfect for storing recovery gear or wet items. While the suspension is tuned for flex and compliance, the bed remains functional with 17 tie-down points and an available 120-volt power outlet. However, the specialized suspension does reduce towing capacity to 5,500 lbs compared to the standard Colorado’s 7,700 lbs.
Safety – Armor and Assistance
Chevy Safety Assist comes standard, providing automatic emergency braking and lane-keep assist for the journey to the trail. Once on the trail, the inherent safety of the Bison comes from its mechanical grip and structural reinforcement. The roll-protection inherent in the cab design is supplemented by the rock sliders, which protect the rocker panels from crushing impacts that could otherwise jam doors shut.
Verdict
The 2026 Colorado ZR2 Bison is a specialized tool for a specific purpose: absolute off-road dominance. It trades some towing capacity and fuel economy for a factory-warrantied ability to tackle Class 4 trails, making it the top choice for serious adventurers.
