Chevy Zr2 Bison 2024. On wednesday, the 2024 chevrolet colorado zr2 bison debuted boasting bigger tires, better breakover and departure angles, and more ground clearance. It really dwarfs the other colorado's in size.

But chevy takes things a bit beyond with changes and upgrades to the wheelbase, the suspension, the running gear, and the pieces that protect all of the sensitive bits on the underside of this truck. At first glance, the bison looks like a slightly beefier version of the standard zr2.
