Performance Specifications
Both the AT4 and AT4X are equipped with a 3.0L Duramax turbo diesel engine as standard, producing 305 horsepower and 495 lb-ft of torque. However, the AT4X offers an optional 6.2L V8 engine, which significantly boosts the horsepower to 420 hp. This makes the AT4X a more powerful option for those who prioritize performance.
In terms of towing capacity, the AT4 can handle up to 9,000 lbs, while the AT4X is rated for slightly less at 8,900 lbs when equipped with the V8 engine. The difference in towing capacity may be negligible for some users but is worth noting for those who need maximum towing capabilities.
Off-Road Capabilities
When it comes to off-road performance, both trims feature a 2-inch factory-installed lift that enhances ground clearance. However, the AT4X takes this a step further with its Multimatic DSSV dampers, which provide superior off-road handling and comfort compared to the standard suspension found in the AT4.
A significant difference lies in the locking differentials: the AT4 does not offer any locking differentials, whereas the AT4X comes equipped with front and rear electronic locking differentials. This feature allows for better traction on challenging terrains, making the AT4X a more capable off-road vehicle.
Design Features
The exterior design of both trims reflects their rugged nature. The AT4 features 18-inch machined aluminum wheels, while the AT4X boasts 18-inch painted aluminum wheels with dark-painted pockets and mud-terrain tires designed for off-road conditions.
Inside, both trims offer high-quality materials and advanced technology. However, the AT4X includes more luxurious features such as 16-way power heated and ventilated front seats with a massage function, compared to the standard 10-way power driver’s seat in the AT4. Additionally, the AT4X has a more refined interior aesthetic with upgraded materials.
Technology and Safety
Both trims come equipped with advanced safety features and technology designed to enhance driving experiences. They include a 12.3-inch driver information center and a 13.4-inch infotainment system that supports various connectivity options.
However, the AT4X adds several premium features as standard, including a head-up display, enhanced audio systems like the 12-speaker Bose Premium Series, and additional camera views for improved visibility during off-road maneuvers.
Pricing and Value
The pricing of these trims reflects their features and capabilities. The base price of the GMC Sierra 1500 AT4 starts lower than that of the AT4X due to its fewer luxury features and performance enhancements. For buyers looking for a balance between off-road capability and everyday usability without breaking the bank, the AT4 may be more appealing.
Conversely, those who prioritize advanced off-road technology, luxury interior features, and higher performance may find that investing in the AT4X is worthwhile despite its higher price point.
