2019 Chevy Colorado Bison Deemed “Wonderfully Designed and Off-Road Capable” By New Atlas


Bison are definitely at home on the open prairie, running through tall grass and over hills. Clint Eastwood himself was one of the American icons that showed through his pictures just how beautiful the High Plains are, and the solitude as well as the struggle for survival than can encompass existing there. Chevy has partnered with AEV to create the Colorado mid-sized pickup truck that has the ability to wander in the same locations that a bison would, and those on staff at New Atlas were excited to test the ZR2 packaged AEV Bison in the crew cab with the diesel engine.

The parts are put on by Chevy, but the experts at AEV add the expertly-placed off-road gear, and it's now a fierce enough contender to compete against the likes of vehicles such as the Gladiator. A standard ZR2 is already well-stacked with off-road gear, but where AEV really shows their full-on expertise is with the duty of shielding. The Colorado receives boron skid plates that protect everything vital underneath the truck, including the transfer case, transmission, both differentials, and fuel tank. There is a more aggressive grille, new interior stitching and badges, wheel flares, and boron steel AEV bumpers.

This is the only Chevy truck that has both front and rear locking differentials, and you are already riding on larger 31-inch tires and a beefier suspension ideal for 4 x 4 setup. AEV claims that the use of boron steel is what enables the skid plates and bumpers to take a hefty amount of abuse and still bounce back relatively unscathed. They have a high amount of resistance for gouging, and also possess a high yield strength that allows them to return to shape after bending on top of low mass. The AEV boron plates actually aren't that much heavier than the aluminum-alloy plates they replace on the standard ZR2.

After you account for everything, you're adding about 200 pounds more weight to the vehicle, and the Bison's suspension spring rates are tuned to properly compensate for the extra weight. The New Atlas testing team chose a virtually impossible hill in the wilds of Wyoming that requires a lot of raw power, clearance, and ability to absorb shocks to conquer. The team realized that they had picked a hill that had a severe lack of breakover clearance, and although the Bison was able to get down with no problem, getting up was a different story.
As was the case with the Gladiator Rubicon, this location was simply so challenging in regards to wheelbase that “If you're stuck, you're stuck”. Many who have ran the Bison hard in areas such as Moab and the Sierras have professed just how capable and trail-dominating it is. It was still decided upon that this is a truck that lives up to its reputation and looks to the fullest when put to the test, and we hope you come to see the Bison along with the rest of our extensive truck lineup right here at West Chevy of Knoxville this back to school season!
