GM working on Chevy Silverado Bison?

The partnership with American Expedition Vehicles will expand following the success of the Colorado ZR2 Bison.

General Motors' collaboration with American Expedition Vehicles could be extended to include the Silverado.

The companies were apparently surprised by the level of demand for the Colorado ZR2 Bison, prompting an increase in production allocation after the first year's run of 2,000 units quickly sold out despite commanding a $5,750 premium over the basic ZR2.
GM has promised to continue its relationship with AEV as it continues to "look at more off-road opportunities," Silverado marketing director Hugh Milne recently told Muscle Cars and Trucks.
When asked specifically about the prospects of a Silverado Bison, Milne did not provide an explicit confirmation but noted "the possibilities are endless" and "I wouldn't rule anything out."
The Colorado ZR2 Bison steps above and beyond the Silverado Trail Boss (pictured), integrating AEV's winch-compatible tube-steel bumper and a set of five steel skid plates. The package also benefits from a lifted suspension with Multimatic DSSV dampers, 31-inch knobby tires and front/rear locking differentials.
Previous rumors have pointed to a Silverado ZRX on the roadmap as a more direct rival to the Ford F-150 Raptor and Ram Rebel TRX. The success of the Raptor and Bison involve two distinct niche markets, one focused on high-speed desert runs and the other for lower-speed rock crawling, and provide room for multiple special editions that engage both groups. Anything involving AEV will presumably involve the latter.
