The formidable Chevrolet ZR2 Bison is a mid-size truck with a massive heart. And a massive everything else like a V6, with gas and diesel options, 31-inch Goodyear Wrangler Duratrac off-road tires, steel underbody skid plates and a menacing lettered grille. Awesome interior features include AEV-logo embroidered headrests and floor panels. It'll be rolling into showrooms in January.
