In an intriguing development, GM Authority spy photographers just caught a Chevy Colorado ZR2 Desert Boss prototype undergoing testing while wearing the beadlock wheels from the upcoming 2024 Chevy Colorado ZR2 Bison.
As the exclusive GM Authority spy shots you can see here show, the wheels of the Chevy Colorado ZR2 Desert Boss match those GM previously teased on the photos it released of its Colorado ZR2 Bison prototype ahead of the Bison’s May 31st, 2023 official debut.
We’re not quite sure why the Chevy Colorado ZR2 Desert Boss prototype in our latest spy shots is wearing the Bison’s beadlock wheels. One possibility is that GM is simply testing the wheel and tire combo for the Bison, using the Desert Boss purely as a test bed.
However, we did spot a difference between the Bison preview photos and our latest shots of the Chevy Colorado ZR2 Desert Boss. The Bison teased by GM is wearing Goodyear Duratrac tires, while the spied prototype is rolling on Goodyear Wrangler Territory MT rubber.
Alternately, The General may be planning to eventually offer the beadlock wheels as an accessory option on the “regular” Chevy Colorado ZR2. Currently, we’re expecting the Desert Boss Special Edition package (RPO code ZDB) to be offered on the 2023 model year only, anticipating that it won’t return for 2024.
However, we do expect some of its components will also be available as accessories for the 2024 Chevy Colorado ZR2. As a refresher, the Desert Boss Special Edition package contains the following off-road upgrades and styling details (relevant RPO codes and feature exclusivity listed in parentheses):
- Black nameplates (RIK)
- Bed-mounted sport bar with “ZR2” sail panel (SBY, exclusive to package)
- Off-Road front bumper with safari bar (SD0, exclusive to package)
- 17-inch beadlock-capable wheels (SMY, exclusive to package)
- 40-inch roof off-road light bar (S3X, exclusive to package)
- Underbody camera (UXA)
- Auxiliary Power Distribution Box (VBP, exclusive to package)
- Front Fender Decal Package (5K5, exclusive to package)
- Tailgate Decal Package (SB7, exclusive to package)
- Bodyside Decal Package (DSA, exclusive to package)
The soon-to-be-unveiled 2024 Chevy Colorado ZR2 Bison is expected to be an indirect replacement for the 2023 Colorado ZR2 Desert Boss. It is a standalone trim level that enhances the truck’s off-road capabilities to a higher level than that offered by the ZR2, which is already a quite capable off-roader.
Some of the features of the Chevy Colorado ZR2 Bison include 35-inch, LT315/70R17 Goodyear Wrangler Duratrac tires, long-travel Multimatic DSSV dampers, hydraulic bump stops, and an extra two inches of ground clearance beyond that offered by the “ordinary” ZR2.
For motivation, the 2024 Chevy Colorado ZR2 Bison will be equipped with the same turbocharged 2.7L I4 L3B Turbo High-Output gasoline engine as in the “regular” ZR2, which develops 310 horsepower and 430 pound-feet of torque.
The updated GM eight-speed automatic transmission will send power from the engine to the wheels, while the 4WD drivetrain will obviously be fitted as standard.
