We drive the 2024 GMC Sierra 2500HD AT4X AEV pickup truck to see if the most rugged GMC HD lives up to the hype.
The AT4X expands the capability of the AT4 by a lot, and the AEV model goes a bit further.
The Sierra HD AT4X AEV is only available at the 2500HD level and is offered exclusively with the standard bed and crew cab.
The AT4X AEV wears 35-inch Goodyear Territory MT tires wrapped in 18-inch AEV aluminum wheels.
Inside the Sierra AT4X AEV is a giant 12.3-inch digital gauge cluster and a 13.4-inch infotainment touchscreen.
The AT4X AEV can tow up to 18,500 pounds and carry a payload of up to nearly 3300 pounds.
Every AT4X AEV comes with a 1.5-inch suspension lift, additional skid plates, AEV hot-stamped steel bumpers, an electronically-locking rear differential, and Multimatic DSSV spool-valve dampers.
The AT4X AEV is available with either a 401-hp gas-fed 6.6-liter V-8 or a 470-hp turbocharged 6.6-liter V-8 Duramax diesel with 975 pound-feet of torque.
With either engine, the AT4X AEV uses a 36-gallon fuel tank.
The 2024 Sierra 2500HD AT4X AEV is $94,290. That's a $9495 extra on top of the AT4X model.
The 2024 Chevrolet Silverado 2500HD ZR2 Bison shares many of its components as the heavy-duty GMC.
