Chevrolet’s Silverado ZR2 Bison Launches For 2023
Chevrolet recently announced the arrival of the first-ever Silverado ZR2 Bison, set to launch for the 2023 model year.
The ZR2 Bison is a collaboration between Chevrolet and American Expedition Vehicles (AEV), a premium off-road aftermarket manufacturer. As you can probably guess by that alone, this special edition model will come from the factory with special off-road enhancements.
For starters, AEV has bolstered the front and rear with stamped steel bumpers; the front bumper is compatible with an available winch. Underneath, the Bison is guarded by five boron steel skid plates, including those protecting the rear differential, transfer case and fuel tank. All four corners are carried by black 18-inch AEV wheels wrapped in 33-inch Goodyear Wrangler Territory MT tires.
When compared to a 2022 Silverado ZR2, the Bison should have an easier time clambering over obstacles. The front approach angle has increased to 32.5 degrees over the ZR2’s 31.8 degrees; departure angle sees only a minor improvement to an estimated 23.4 degrees compared to 23.3 degrees. Both trucks should have roughly the same ground clearance of 11.2 inches.
Outside of that, the Bison will naturally carry many of the ZR2’s standard features, like a 6.2-liter V8 engine (420 horsepower and 460 lb-ft of torque), Multimatic DSSV dampers, front and rear e-lockers, and specific off-road chassis and suspension calibrations, just to name a few. There’s also a “Terrain Mode” for one-pedal rock crawling.
