2023 GMC Canyon AT4 Spied High-Altitude Testing

General Motors is gearing up to release an all-new third generation for the GMC Canyon pickup truck, introducing a raft of changes and updates with the overhauled 2023-model-year vehicle. Now, we have new spy photos that reveal the 2023 GMC Canyon AT4 off-roader conducting some real-world high-altitude testing in Colorado.

Under all the camouflage and covers, the 2023 GMC Canyon AT4 boasts aggressive styling highlighted by flared fenders and a raised ride height. Also note that this prototype model isn’t equipped with running boards, unlike the low-hanging chrome running boards spotted on the 2023 GMC Canyon Denali prototype that GM Authority covered in June.

Naturally, the 2023 GMC Canyon will offer loads of ground clearance, which means any running boards that are offered will be available as an optional extra and will hug the body. That emphasis on clearance will continue to the revised front fascia, which will offer an aggressive approach angle for those looking to tackle some trails. The new front fascia will also have new LED lighting with vertically oriented signatures.

In the corners, this 2023 GMC Canyon AT4 prototype rides on a set of Goodyear Wrangler Territory AT tires, sized at 265/65R18. To note, the Goodyear Wrangler Territory AT tires are less aggressive than the Goodyear Wrangler Territory MT tires spotted on the 2023 GMC Canyon AT4 prototype GM Authority covered back in June. What’s more, it’s worth mentioning that the Goodyear Wrangler Territory MT tires equipped by the GMC Canyon AT4 prototype covered in June are the same tires equipped on the recently released Chevy Silverado ZR2.

Under the skin, the 2023 GMC Canyon will ride on an updated version of the current GMT-31XX midsize body-one-frame platform, dubbed 31XX-2. The exterior styling and interior will both be completely revised, while under the hood, the pickup will run the all-new turbocharged 2.7L I4 L3B gasoline engine. The L3B is also offered in the current GMC Sierra 1500, where it’s rated at 310 horsepower and 348 pound-feet of torque, as well as the refreshed 2022 Chevy Silverado 1500, where it produces 20 percent more torque for 420 pound-feet total.  A 10-speed automatic will be on deck for shifting.

As covered previously, the naturally aspirated 2.5L I4 LCV gasoline engine, naturally aspirated 3.6L V6 LGZ gasoline engine, and 2.8L I4 LWN turbodiesel Duramax, all of which are available with the current GMC Canyon, will no longer be offered with the 2023 model year.

One final note – General Motors is also expected to debut the new GMC Canyon AT4X with the 2023 model year, giving off-roading enthusiasts an even more-capable trim level option in the new Canyon lineup. The prototype here, however, appears to be the “standard” AT4.
