2019 Colorado ZR2 Bison Test Drive Proves It to Be Most Off-Road Ready in its Class

Auto journalist Gary Gastelu has completed in-depth tests of just about every type of vehicle in existence, and we knew that he was going to enjoy getting his hands on the pre-customized Chevy Colorado ZR2 Bison. All of us here at West Chevy of Knoxville have long admired the work that American Expedition Vehicles has done on cars for years now. The Brute Double Cab was an amazingly-built Wrangler Unlimited that was converted into a pickup, and a close look at its custom accessories let one know that they could work wonders with something such as the ZR2.

The raw goods are a steel set of bumpers with a winch mount in the front, wide black fender flares, black 17-inch alloy wheels, a Chevy branded grille, and five boron steel skid plates. All the additives mean about 200 extra pounds added to the truck, but it is evenly enough spread so the balance is not too upset. Gary immediately billed the ZR2 as “the most off-road capable vehicle Chevrolet has ever made”. Thanks to front and rear locking differentials, a two-inch lifted suspension and Multimatic “spool valve” dampers the truck is capable of anything ranging from high-speed off-roading to taking jumps and crawling over obstacles such as rocks.

The official ground clearance for the Bison is 8.9 inches, which at first may not sound impressive but is measured under the suspension mounts instead of right in the center of the truck. The Bison is available in extended and crew cab versions and with either a 3.6-liter V6 or a 2.0-liter 4-cylinder turbodiesel. As Gary began his test drive he thought that the control layout was spot-on, and what it is missing in luxury elements is ideal with off-road handling in mind.

This video does a great job of getting all of the ways underneath and showing us the five boron skid plates that prevent the underside from taking a severe beating during off-road duty. The track that the Bison was tested on was far from a breeze: rocks of all sizes were strewn all over, and you see the truck navigate a massively washed out puddle turned-into-stream. Gary is even shown catching sizable air on a tabletop, putting about everything you could imagine to the test during landing. The bison is a rather limited-edition truck for the 2019 year, but we want to invite you to the lot here this fall: check out the full range of trucks for sale, and see which one will be the perfect fit for your growing family or business!
