2023 Chevrolet Silverado Gains Adventure-Ready ZR2 Bison and Upgraded Diesel Engine


Chevrolet introduced the trail-ready Silverado ZR2 last year and now the company is taking it even further with the new Silverado ZR2 Bison.

Built in conjunction with American Expedition Vehicles, the pickup builds on the success of the smaller Colorado ZR2 Bison and is designed to be the “ultimate half-ton truck for backcountry adventures.”

In order to claim this title, the Silverado ZR2 Bison was fitted with rugged powder coated bumpers made of 0.1 inch (3 mm) thick steel. The bumpers also have recovery points and running boards, while the front bumper has been designed to accommodate an available winch.

Speaking of protection, shoppers will find press-hardened steel underbody skid plates that are “three and a half times stronger than an equivalent cold-stamped high-tensile steel plate.” The truck is also equipped with steel skids and exclusive 18-inch AEV wheels, which feature a gloss black finish along with 33-inch Goodyear Wrangler Territory MT tires.

Thanks to these changes, the approach angle should climb from 31.8 to 32.5 degrees while the departure angle should also improve slightly to 23.4 degrees. That being said, the truck’s ground clearance should remain at 11.2 inches (284 mm).

Another thing that doesn’t change is the ZR2’s impressive off-road kit collection that includes Multimatic DSSV spool dampers, travel-maximizing springs and a Terrain mode that allows crawling with just one pedal. The truck also sports front and rear electronic lockers along with a 6.2-liter V8 developing 420 hp (313 kW / 426 hp) and 460 lb-ft (624 Nm) of torque.

Off-road features aside, the Silverado ZR2 Bison is distinguished by an exclusive body-colored grille bar and matte black accent on the Multi-Flex tailgate. Buyers will also find Bison decals as well as a stylish interior with AEV badging on the headrests and all-weather floor mats.

The Silverado ZR2 Bison is expected to enter production early next year and pricing will start at $78,490 including destination. That makes for an expensive pickup as the model costs about $8,000 more than the 2022 Silverado ZR2.

The 2023 Silverado gets a more powerful diesel engine

Along with the ZR2 Bison, the 2023 Silverado gets an upgraded 3.0-liter turbodiesel inline-six. Now in its second generation, the engine features new steel pistons with a revised combustion bowl, retuned turbocharger, new fuel injectors and improved temperature control features.

These updates allow the engine to produce 305 hp (227 kW / 309 hp) and 495 lb-ft (670 Nm) of torque, an increase of 28 hp (21 kW / 28 hp) and 35 lb-ft (47 nm). These are significant gains and they should help improve what was already one of our favorite diesel engines.

The updated diesel should be available by the end of the year and it will continue to be mated to a ten-speed automatic transmission. It will be offered on a handful of trims, including the Custom Trail Boss, LT, RST, LT Trail Boss, LTZ and High Country.
