2023 GMC Sierra 1500 AT4X: The Ultimate Off-Road GMC

The ultimate off-road GMC truck is now the 2023 Sierra 1500 AT4X. This impressive pickup brings the power and equipment required for some adventures that take you deep into the wilderness.

For generations, the GMC Sierra has been the symbol of luxury truck driving. This pickup typically includes the comfort and quality features you don’t find on any other truck. Over the past year, GMC has taken a turn toward more off-road-focused truck. We saw this with the new GMC Canyon and now witness the same with this incredible AT4X trim for the half-ton Sierra.

Which powertrain does the AT4X use?

This off-road trim comes with the most powerful V8 engine in the Sierra lineup. This means you’ve got a 6.2-liter V8 engine pumping out 420 horsepower and 460 lb-ft of torque when you choose the AT4X. This engine mates to an impressive 10-speed automatic transmission to deliver the power to all four wheels. Its pretty easy to tackle the trails and challenges of the wilderness when you’ve got a truck with plenty of power for the job. If you need to tow a trailer, this trim can handle up to 8,700 pounds for you.

What features are specific to this trim?

The 2023 GMC Sierra 1500 AT4X builds on the AT4 trim with more off-road features and upgraded technology to give you more for your adventures. In this trim, you’ll find:

• 18-inch black wheels

AEV got their hands on this Sierra

How can you make an already impressive off-road truck even better? Let the team at American Expedition Vehicles take a crack at it. The AEV package improves this truck, while adding quite a bit to the price, to make it more impressive. This special version of the 2023 Sierra 1500 AT4X brings 33-inch Goodyear Wrangler Territory Mud-Terrain tires, a new steel bumper, and five boron steel skid plates. The bumper is one of the most interesting upgrades. This item increases the approach angle to 32.5 degrees compared to the 31.8 degrees for the regular AT4X.

Does the AT4X sit higher than other Sierras?

The two off-road trims of this truck sit higher than the rest of the lineup. The AT4 and AT4X both benefit from suspension upgrades, a 2-inch lift kit, and the rugged appearance packages that let you know these trucks mean business. The AT4X has more off-road features than the AT4, putting it at the head of the class when it comes to off-road driving.

Can you stay connected while driving this truck?

We’re focused on the off-road credentials of the new 2023 GMC Sierra 1500 AT4X, but it includes plenty of tech and connectivity items for you. This truck features a 13.4-inch touchscreen as part of the standard package. You’ll enjoy the benefits of wireless Android Auto and Apple CarPlay, Sirius XM, voice control, and a built-in Google interface.

Does this truck reach the levels of the Raptor or TRX models?

The AT4X, even the AEV Edition, of this GMC Sierra doesn’t compete with the Ford F-150 Raptor or Ram 1500 TRX. Those trucks include high-output engines for fast-paced off-roading across the desert sand. That said, the AT4X takes on other versions of the Ford F-150 and Ram 1500 and stands toe-to-toe with those trucks.
This GMC truck is great for some fun in the wilderness when you want to go mudding, take a camping trip, pull a boat to a remote lake, or just get lost in the outdoors where you can leave the rest of the world behind you.

This truck is right for serious off-roading

In previous model years, the AT4 trim was where the off-road credentials of the Sierra ended. That’s no longer the case. This big brute brings you the features you want for some fun in the outdoors along with the comfort to enjoy the drive when you’re heading to work during the week. You won’t every feel shorted when you’re behind the wheel of this full-size luxury pickup truck.
