2023 Chevrolet Silverado 1500 Adds More Efficient Diesel Engine and ZR2 Bison Leads the Range

What is a Silverado 1500?

The Chevrolet Silverado 1500 gave a major update last year, yet the Bowtie continues to update its popular full-size pickup. The Silverado 1500 lineup will expand for 2023 to include the off-road-focused ZR2 Bison Special Edition, as well as a more powerful Duramax diesel engine.

How did Chevy upgrade the Silverado 1500 diesel engine?

Chevrolet offers the Silverado 1500 with a variety of engines, from a turbocharged four-cylinder to a 6.2-liter V8. A turbocharged 3.0-liter inline-six diesel is also available on most models, with production reaching 2023. While previous oil-burner versions topped out 277 hp and 460 lb-ft of torque, the revised 2023 engine produces 305 hp and 495 lb-ft. Foot. Chevrolet cites new steel pistons and fuel injectors, a revised turbo compressor and “improved temperature control features” as sources for increased production.

What is a Silverado 1500 ZR2 Bison?

The ZR2 Bison, on the other hand, uses the most powerful engine of the bunch: a 6.2-liter V8 petrol engine with 420 horsepower and 460 pound-feet of torque. Based on the already capable ZR2, the Bison was co-developed with third-party supplier American Expedition Vehicles to be the ultimate off-road vehicle. Powder-coated steel AEV front and rear bumpers provide the ZR2 Bison’s optimized approach and departure angles of 32.5 degrees and 23.4 degrees, respectively, without changing the ground clearance of 11.2 inches. Other mechanical improvements include boron steel skid plates, steel sway bar protection, and 18-inch gloss black AEV wheels wrapped in 33-inch Goodyear Wrangler Territory MT tires.

Visual improvements to the ZR2 Bison abound, starting with the exterior details. The body-color grille fender is unique to Bison, as is the matte black upper element of the standard Multi-Flex tailgate. There are also AEV-branded badges and badges throughout the cabin and on the exteriors.

How much does all this cost?

We don’t know for sure how much a diesel will cost, but the current engine is $2,500-$3,000 on a four-cylinder (depending on trim) and about $1,000 more expensive than a 5.3-liter V8. Expect prices to remain firm when the 2023 Silverado goes on sale later this year.

Chevrolet has released pricing for the ZR2 Bison. With production starting in early 2023, the Bison will carry a base price tag of $78,490, including destination fees. That means the fenders, skid plates and styling cues will save you about $8,500 over the cost of a standard Silverado 1500 ZR2.

Chevy isn’t resting on its laurels a year after its well-received Silverado 1500 upgrade. The diesel makes somewhat more power, while buyers with deep pockets can now select the more capable ZR2 Bison.
