AEV marketing manager Matt Felderman told Muscle Cars & Trucks that 2020 capacity would grow.

The 2,000 Colorado ZR2 Bison allotment sold out before the first Bison was delivered late last year.

GM and American Expedition Vehicles are increasing Bison supplies this year to meet demand.

I'd be careful about increasing bison volume. 

You wouldn't want to leap to 6,000 units and become aggressive because you don't want half of them

AEV off-road equipment upgrades the Chevrolet Colorado ZR2 Bison. 

snorkels, 31-inch Goodyear Wrangler Duratrac off-road tyres, and Multimatic DSSV dampers are optional. 

Both 3.6-L V6 and 2.7-L Duramax diesel Bisons have 8-speed automatic transmissions.
