2021 GMC Canyon AT4 Isn’t Quite the Colorado ZR2 Twin We Hoped For

The Canyon AT4 maintains footing on all surfaces with an automatic locking Eaton rear differential, four-wheel-drive transfer case, and 31-inch Goodyear Wrangler Duratrac tires on 17-inch aluminum wheels. These features cooperate with retuned off-road suspension to keep the Canyon's underbelly off the trail. Should the Advanced Hill Descent Control System somehow not be enough to stop you from exuberantly bottoming out on a boulder, a skid plate will take the blow rather than the transfer case.

GM's 3.6-liter V6 powers the AT4 as standard, its 308 horsepower and 275 pound-feet of torque more than adequate to take the Canyon anywhere it can go. Seeing as the GMC is already the premium option, it'd be sort of a shame not to match the AT4's distinct interior—which features model-specific headrest embroidery and unique "Kalahari" stitching—with an upmarket engine, specifically a 2.8-liter Duramax turbodiesel, which produces 181 horsepower and 369 pound-feet of torque.

If the AT4's larger, "dark chrome" grille and red recovery hooks call your name, then plan a day off to visit a GMC dealer sometime in the year's second quarter. Pricing hasn't yet been announced, but going by current price schemes for the Chevrolet Colorado and GMC Canyon in crew-cab, short-bed configuration, nobody should be surprised to see 2021 AT4s start close to $45,000. Those built with the Duramax diesel may yet scratch $50,000—a steep price for any midsize truck.
