Auto Buyers Guide gave the 2024 GMC Sierra 2500 HD AT4X AEV a solid 76/100 rating, praising its exceptional livability and performance across the board. The truck excels with its innovative trick tailgate featuring barn doors (unique to the segment), massaging luxury-car-style seats, and a potent 6.6L Duramax Diesel delivering 975 pound-feet of torque—significantly outpowering competitors like the Power Wagon. However, value is a significant drawback, with the fully equipped diesel AT4X AEV starting around $102,000, making it one of the priciest trucks in its class. This truck is built for buyers who prioritize off-road capability, towing power, and interior comfort over affordability and are willing to pay premium pricing for a unique feature set.

Redline Reviews gives the 2024 GMC Sierra 2500 HD AT4X a strong 79/100 rating, praising its exceptional design and performance, including the striking red and black two-tone styling with new LED lighting and the impressive 6.6L Duramax diesel that delivers 470 horsepower and 975 lb-ft of torque. The truck excels in livability with 11.5 inches of ground clearance, power retractable running boards, and a multi-pro tailgate, while the cabin tech features a 13.4-inch Google-based infotainment system with wireless Apple CarPlay and Android Auto. The main caveat is the steep $95,000 price tag—roughly $20,000 more than the regular AT4—which significantly impacts the value proposition despite the truck's off-road capabilities and luxury features. This truck is built for buyers who prioritize premium off-road performance and advanced technology over affordability.
