2023 Chevrolet Silverado Arrives With New ZR2 Bison And Upgraded Duramax Diesel

Reveal / 6 Comments

Chevrolet teamed up with American Expedition Vehicle to design the ultimate overlander.

Earlier this year, Chevrolet introduced the Silverado 1500 ZR2. While the rest of the range is quite good, the ZR2 received a lukewarm reception because of its naturally aspirated 6.2-liter V8 engine and recommended retail price. Chevy charges $70,195 for the ZR2, which makes it $360 more expensive than the famous F-150 Raptor. When you compare the two, the Ford comes out on top.

Chevrolet hopes to make the ZR2 more attractive by reintroducing the beloved Bison nomenclature, previously available on the Colorado.

This is the first-ever Silverado ZR2 Bison, designed in collaboration with American Expedition Vehicles (AEV), a manufacturer of premium aftermarket off-road accessories.

"Our most recent collaboration with AEV resulted in the much-acclaimed Colorado ZR2 Bison. We're thrilled to team up again to bring customers Chevrolet's next chapter of off-road dominance, this time on Silverado," said Scott Bell, Chevrolet vice president.

The Silverado ZR2 Bison is meant to be the pinnacle of the nameplate's off-road capability.

According to Chevy, it teamed up with AEV again because of the success of the previous Bison. AEV has a solid connection to overlanding, so GM chose to partner with it again. The result is the Bison with several unique overlanding parts.

"The Chevrolet Silverado ZR2 Bison is the ultimate half-ton truck for backcountry adventures," said AEV CEO and Founder Dave Harriton. "The Silverado ZR2 Bison checks all the boxes - robust stamped steel bumpers, complete underbody protection, a factory-tuned off-road suspension, and locking differentials front and rear. We are confident off-road enthusiasts are going to love this truck."

The Bison has the same ground clearance as the ZR2 (11.2 inches) but improves the approach and departure angles. The approach angle is now 32.5 degrees, up from 31.8 degrees, while the departure angle is up to 23.4 from 23.3 degrees.

While the above increases aren't that significant, owners can take comfort knowing that the front, rear, and underside are protected by 0.1-inch steel. The press-hardened steel used for the underbody skid plates is three-and-a-half times stronger than an equivalent cold-stamped high-strength steel.

Additional AEV features include front and rear bumpers made from the same stamped steel, heavy-duty recovery points, and space for a winch in the front bumper. Finally, a set of 18-inch gloss black AEV wheels with 33-inch Goodyear Wrangler Territory MT tires are standard.

The Bison also gets all of the ZR2's existing standard features, which includes the 6.2-liter V8 producing 420 horsepower and 460 lb-ft of torque. A 10-speed automatic transmission is standard.

Standard off-road kit includes front and rear e-lockers, Multimatic 40-millimeter DSSV spool-valve dampers, and uniquely tuned springs that provide more wheel articulation.

As a nod to the name and the collaboration with AEV, this ZR2 has a Bison decal on the side outer box and the AEV badge featured on the front headrests and all-weather floor liners.

Chevrolet will start production of the Bison in early 2023, and it retails for $78,490 with dealer freight charge included.

In addition to the new Bison trim, Chevrolet will also introduce an upgraded Duramax diesel option for the 2023 model year. According to the Chevrolet, the refined version of the 3.0-liter turbocharged inline-six produces 305 hp and 495 lb-ft of torque. That's an increase of 10% (277 hp) and 7.6% (460 lb-ft), respectively.

Upgrades to the diesel powertrain include new steel pistons with a revised combustion bowl, a retuned turbo compressor, new fuel injectors, and improved temperature control.

"These improvements to the popular 3.0L Diesel Duramax build on the already advanced design of the first-generation engine," said John Barta, assistant chief engineer of diesel engines. "We often hear customers express their satisfaction with the outstanding fuel economy and smooth, quiet power of the current diesel engine, so we can't wait for them to experience this advanced engine made possible by the continued design evolution and advances in engine technologies."

The upgraded diesel will be available on Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, and High Country trims. It will be paired to a ten-speed automatic transmission.

It will be available on select trims of the 2023 Silverado by the end of the year.
