GMC's heavy-duty truck lineup has consistently set benchmarks for power, capability, and luxury. The new 2024 Sierra HD AT4X and the AT4X AEV Edition represent the pinnacle of off-road capability within the Sierra HD range and result from a robust partnership with American Expedition Vehicles (AEV). Positioned confidently in the heavy-duty truck market, these trucks promise a blend of ruggedness, advanced technology, and superior comfort.
Design and Exterior Features
For the 2024 model year, the AT4X features a unique grille with bold badging, giving it a commanding presence on the road. If you seek an extra touch of exclusivity, the AEV Edition takes it a step further with unique badges. The AT4X has 20-inch Gloss-Black aluminum wheels with 35-inch Goodyear Wrangler Territory MT tires to navigate the toughest trails. The AEV Edition features 18-inch Salta wheels and 35-inch Goodyear Wrangler Territory MT tires, adding to its ruggedness.
While both models are built for off-road adventures, the AEV Edition ups the ante with enhancements tailored for extreme environments. Its front bumper offers winch capability for extreme off-roading, while a boron steel approach skid plate protects the vehicle's underside against rough terrain.
Performance and Capabilities
The 2024 GMC Sierra HD AT4X and AT4X AEV Edition utilize the same engine options, providing a choice between a gasoline engine and a powerful Duramax diesel engine. Both the 6.6L V-8 gas engine and the 6.6L Duramax Turbo-Diesel V-8 are paired with a 10-speed Allison transmission for smooth, responsive handling on any terrain.
Both models offer impressive towing power, with a maximum conventional towing capacity of 18,500 pounds and a gooseneck/fifth-wheel towing capacity of 18,000 pounds. Their payload capacity also shines at 3,304 pounds, making them serious contenders for hauling heavy cargo in the competitive heavy-duty segment. Compared to competitors such as the Ford F-250 TREMOR and Ram 2500 Power Wagon, the Sierra HD AT4X and AT4X AEV Edition offer superior off-road capabilities and features.
Off-Road Features
While both models are designed for off-road performance, the AT4X AEV Edition edges ahead with better ground clearance. The AT4X's approach angle is 31.6 degrees, while that of the AEV Edition is 29.8 degrees. The choice between the two may depend on specific needs for off-road performance versus additional camera views for trailering.
Both trucks come with a 1.5-inch suspension lift, giving them plenty of ground clearance to tackle rough, uneven terrain with ease. The AT4X AEV Edition is equipped with stamped-steel skid plates, providing superior protection against rocks and debris, while the standard AT4X uses aluminum skid plates. It also offers a slightly higher ground clearance of 11.8 inches compared to 11.6 inches of the AT4X, enhancing its capability on rugged terrains. Some of its other enhancements include the following:
- Enhanced approach and departure angles
- Increased underbody protection
- AEV-tuned off-road performance upgrades
Interior Comfort and Features
The 2024 GMC Sierra HD AT4X and AT4X AEV Edition provide ultimate comfort with six-way heated and ventilated front seats with added massage functionality. The AEV Edition also features exclusive AEV branding. Both models have an Obsidian Rush interior with full-grain leather and wood accents that create an exclusive cabin experience. These vehicles are both spacious and can comfortably accommodate up to five passengers.
Although both models offer practical storage solutions, the AEV Edition enhances this with additional rugged features tailored for off-road use. It also offers specialized off-road navigation features for adventurous driving on rugged terrains.
Technology and Safety
Both models feature advanced infotainment systems designed to enhance your driving experience. These systems offer a 13.4-inch diagonal center touch screen as the primary interface for navigation, media, and vehicle settings. A 12.3-inch digital driver information center allows you to customize the display settings. The high-resolution infotainment display provides clear visuals and responsive touch functionality.
The AT4X and AT4X AEV Edition also have a 12-speaker Bose Premium Series sound system, delivering rich, immersive audio. The infotainment system of both models has the next-generation GMC Infotainment System with Google built-in for seamless connectivity.
Driver-Assistance Technologies
The 2024 GMC Sierra HD AT4X and the AT4X AEV Edition are equipped with advanced driver-assistance technologies, which enhance safety and performance, particularly in towing scenarios. The Sierra HD Pro Safety package offers a suite of driver-assistance features, which includes the following as standard:
- Forward collision alert
- Automatic emergency braking
- Lane departure warning
Both vehicles also offer adaptive cruise control with trailering, high-definition surround vision, and trailer side blind-zone alert as available features. The AT4X offers up to 13 camera views, while the AT4X AEV Edition expands this to 14 views, enhancing visibility when towing and maneuvering in tight spaces.
Comparison With Competitors
When compared to heavy-duty rivals such as the Ford F-250 TREMOR and the Ram 2500 Power Wagon, the 2024 GMC Sierra HD AT4X and AT4X AEV Edition stand out with their unique combination of off-road capability, luxury, and advanced technology features. Their superior towing and payload capacities and state-of-the-art suspension and off-road systems make them ideal, whether you're an adventurer or a professional.
