What is the top of the line Chevy Colorado?
The top-trim Chevrolet Colorado is the ZR2, the off-road-focused variant; for even more rugged capability, Chevrolet has offered the ZR2 Bison as a limited-edition edition within that lineup.
Top trim overview
The Colorado's hierarchy places the ZR2 at the peak of the lineup. It is designed for serious off-roading with upgraded suspension, protective hardware, and specialized styling that sets it apart from the WT, LT, and Z71 models.
Availability and equipment can vary by model year and market. The ZR2 remains the pinnacle of Chevrolet's Colorado lineup in recent years, with the ZR2 Bison serving as a higher-spec, limited-edition variant within that same family.
Here are the key features that distinguish the ZR2 and explain why it sits atop the Colorado lineup.
- Off-road-focused suspension tuned for rugged terrain
- Front and rear locking differentials for maximum traction off-road
- Protective skid plates and rock sliders to shield underbody components
- Upgraded dampers and tires designed for challenging surfaces
- Distinctive exterior styling and higher ground clearance
These features collectively position the ZR2 as Chevrolet's top-performing Colorado, optimized for off-road adventures and desert runs alike.
ZR2 Bison: a limited-edition upgrade
In addition to the standard ZR2, Chevrolet has offered the ZR2 Bison, a limited edition developed with American Expedition Vehicles (AEV) that outfits the truck with enhanced protection, a stronger bumper, and other rugged details tailored for serious expeditions.
Before listing its enhancements, note that the Bison edition is not always available every model year and is typically produced in limited quantities.
- Exclusive AEV-designed front bumper and enhanced underbody protection
- Reinforced rock rails, skid plates, and armor for deeper off-road use
- Distinctive badging and styling cues to differentiate it from the standard ZR2
- Notable weight and price premium reflecting its specialized components
The Bison edition represents the extreme end of Colorado off-road capability, appealing to enthusiasts who want factory-backed, ready-for-trails hardware right from the showroom.
How to decide between trims
For most buyers, the choice comes down to budget and how often they’ll tow or drive off-road. While the ZR2 offers significant off-road capability, the base WT and mid-range LT models cover everyday use with better fuel economy and lower upfront cost. The Z71 trim adds some off-road capability without reaching the extreme performance of the ZR2.
Availability of trims and features can vary by model year and market, so checking with a local dealer or the manufacturer’s site for the current configuration is recommended.
Summary
The Chevrolet Colorado’s top-line variant is the ZR2, designed for authentic off-road performance. The ZR2 Bison is a limited edition within that lineup, offering additional protection and equipment for the most demanding terrain. For buyers, the key is balancing budget with the intended use—daily driving versus adventurous off-roading.
