The most obvious thing Chevy’s designers have nailed is the Colorado ZR2’s stance. It’s wide, but not detrimentally so when you’re on the trails, and it looks sharp and powerful. It sits high with a 10.7-inch ride height, which is over an inch higher than the Colorado Trail Boss. The approach angle for obstacles is 38.3 degrees, the departure angle is 24.1 degrees, and a breakover angle of 24.6 degrees. Upgrading to the Bison (the name comes from the Bison logo used by Chevrolet’s partners for the trim level, American Expedition Vehicles, or AEV), ups those figures to 38.2/26/26.9 degrees, respectively and increases ground clearance to 12.2 inches. It also adds 35-inch Goodyear Wrangler tires over the standard 32-inch rubber, steel bumpers with a heavy-duty winch-capable front bumper, and an upgrade to Multimatic Jounce Control Dampers (jounce, meaning ‘jolt and bounce’).
The ZR2 trim, of course, comes with badges and dedicated accents, including red tow hooks and a red-accented ‘Flowtie’ emblem. The Bison version is identified with special graphics, too.
