Following up on our studying of the 2021 GM Fleet Order Guide for the Chevrolet Colorado and GMC Canyon, there are more details to share. We’ve already told you about the upcoming suspension leveling kit for the GM midsize trucks, and now there’s further details about a special package for the 2021 GMC Canyon AT4 called the Off-Road Performance Edition. Here’s what the dealer order guide states:
The new 2021 GMC Canyon AT4 Off Road Performance Edition will feature gloss-black 17-inch aluminum wheels, a performance exhaust tip, and black AT4 badges. But it’s more than just that, as the package adds skid plates, rocker panel protection, as well as the previously mentioned leveling kit. The interior will see all-weather floor liners for easier cleaning.
From the sounds of it, the 2021 Canyon AT4 Off Road Performance Edition is the closest the truck will get to its more adventurous cousin, the Chevrolet Colorado ZR2. Missing still will be the high approach angle front and rear fascias, as well as the uniquely tuned spool valve dampers from Multimatic. Expect pricing and photos to be revealed when the 2021 GMC Canyon AT4 launches in the second half of this year.
To recap, the 2021 Canyon AT4 effectively replaces the All Terrain package from years prior. The truck carries standard features including 31-inch Goodyear Wrangler DuraTrac tires fitted to 17-inch aluminum wheels, an off-road tuned suspension with Advanced Hill Descent Control System, four-wheel drive with an Eaton G80 rear locking differential, a transfer case skid plate, red tow hooks, and unique stitching and accents inside the cabin.
Under the hood of the GMC Canyon AT4 is the choice of two unchanged engines. The standard mill is GM’s ubiquitous 3.6L V6 engine with 308 horsepower and 275 lb-ft of torque, while the upgrade is a 2.8L Duramax four cylinder turbodiesel with 181 horsepower and 369 lb-ft of torque.
