2023 Chevrolet Silverado ZR2 Bison Goes Where the Buffalo Roam

• Chevy is bringing the ZR2 Bison trim level to its Silverado pickup.

• As with the Colorado ZR2 Bison, the model is a collaboration with American Expedition Vehicles.

• The Silverado ZR2 Bison goes on sale this fall, priced at $78,490.

After being hunted nearly to extinction, the American bison has slowly come back in the West and is a common sight at Yellowstone National Park. At Chevrolet, the genus ZR2 Bison is an even more common sight, and its population is about to double, with a new Silverado ZR2 Bison pickup joining the Colorado ZR2 Bison that has been roaming Chevy dealer lots since 2019.

Like the mid-size Colorado ZR2 Bison, the new Silverado was developed with off-road specialists American Expedition Vehicles (AEV) and will be the model's most hardcore off-roader. It's based on the existing ZR2 (which continues), adding five underbody skid plates along with rocker-panel protectors and replacing the front and rear bumpers with redesigned stamped-steel units that integrate step plates and front tow hooks. Gloss black 18-inch wheels are wrapped with 33-inch Goodyear Wrangler Territory MT tires. The new bumpers allow for steeper approach and departure angles, although exact figures aren't yet available. Chevrolet is estimating 32.5 degrees for the approach angle and 23.4 degrees for the departure angle. Ground clearance is unchanged at 11.2 inches.
