General Motors recently unveiled the all-new 2023 Chevy Silverado ZR2 Bison, offering up a brand-new off-road package developed in collaboration with American Expedition Vehicles (AEV). Now, we’re learning that development of the Silverado ZR2 Bison took less than two years.
In fact, the Silverado ZR2 Bison program only took 18 months to flesh out, a relatively quick timeline.
“We’ve been doing some work on it for some time now and it probably wasn’t official until the beginning of ’21, so that puts us at just around 18 months,” Silverado Product Manager Sean Cratty explained to GM Authority Executive Editor, Alex Luft, in a recent interview.
The reason for the speedy development timeframe is the already-established relationship between GM and AEV. In fact, the 2023 Silverado ZR2 Bison is the second vehicle created as a result of the collaboration between the two firms, with the last-gen Colorado ZR2 Bison being the first.
The fruits of the collaboration don’t end with the Silverado ZR2 Bison or the Colorado ZR2 Bison, as GM recently revealed the GMC Sierra 1500 AT4X AEV Edition. In fact, the “regular” Sierra 1500 AT4X will get AEV components as standard in mid-2023. From there, GM and AEV are working on a GMC Canyon AT4X AEV Edition, which would also mean that a Colorado ZR2 Bison variant of the new-for-2023 Colorado isn’t that far off.
As a reminder, the 2023 Chevy Silverado ZR2 Bison is an optional package offered on the Silverado ZR2 that aims to deliver enhanced off-road performance and protection. These upgrades include custom AEV stamped front and rear steel bumpers with integrated recovery points and step pads, as well as compatibility up front for an available winch accessory. Additionally, the off-road pickup gets factory-tuned off-road suspension with 40 mm DSSV spool-valve dampers and 11.2 inches of ground clearance.
Shielding the underbody, the Silverado ZR2 Bison is equipped with skid plates, which are mounted to protect the front, rear differential, transfer case, and fuel tank. 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 plate and provides incredible resistance to underbody damage.
As for rollers, we find exclusive gloss black 18-inch AEV wheels wrapped in 33-inch Goodyear Wrangler Territory MT tires.
Under the hood, the new Silverado ZR2 Bison is equipped with the familiar naturally aspirated 6.2L V8 L87 gasoline engine as standard, rated at 420 horsepower and 460 pound-feet of torque. Output is directed through the GM 10-speed automatic transmission, while front and rear e-lockers ensure that the power will reach the ground.
Production of the 2023 Chevy Silverado ZR2 Bison will begin early next year. Pricing starts at $78,490, including destination freight charge (DFC).
