Chevrolet introduced the Silverado ZR2 last year and now has the ZR2 Bison.

The pickup was built with American Expedition Vehicles to be the "ultimate half-ton truck for backcountry adventures."

The Silverado ZR2 Bison has powder-coated, 0.1-inch (3-mm) thick steel bumpers for this title. The bumpers have recovery points, step pads, and the front bumper can accommodate a winch.

Underbody skid plates are three-and-a-half times stronger than a cold-stamped high-strength steel plate. The truck has steel rock sliders, black 18-inch AEV wheels, and 33-inch Goodyear Wrangler Territory MT tires.

These changes should increase the approach angle from 31.8 to 32.5 degrees and the departure angle to 23.4 degrees. The truck's ground clearance will be 11.2 inches (284 mm).

The ZR2's off-road kit includes Multimatic DSSV spool-valve dampers, travel-maximizing springs, and a Terrain Mode for one-pedal rock crawling. The truck has front and rear e-lockers and a 6.2-liter V8 with 420 hp and 460 lb-ft of torque.

The Silverado ZR2 Bison has a body-color grille bar and matte black Multi-Flex tailgate. Bison decals, AEV headrest logos, and all-weather floor mats are also included.

The Silverado ZR2 Bison will be available early next year for $78,490 including destination. The model costs $8,000 more than the 2022 Silverado ZR2.

The 2023 Silverado also gets a 3.0-liter turbodiesel inline-six engine. Second-generation engine features new steel pistons, a revised combustion bowl, a retuned turbo compressor, new fuel injectors, and improved temperature control.

These updates increase the engine's power by 28 hp (21 kW / 28 PS) and torque by 35 lb-ft (670 Nm) (47 Nm). These improvements should help our favorite diesel engine.

The updated diesel will be available by year's end with a ten-speed automatic transmission. Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, and High Country will offer it.
