The choice of engine will be a critical decision for buyers, depending on their specific needs, from towing to off-roading. Likely, GMC will offer the tried-and-true 6.6L Duramax Turbo-Diesel V8, renowned for its incredible torque and pulling power.

Expect impressive horsepower and torque figures, ensuring the AT4X AEV can conquer any challenge you throw its way. GMC's engineers may have further refined this engine for the 2025 model year, potentially increasing efficiency and reducing emissions while retaining its robust performance characteristics.

Alternatively, a gasoline engine option might be available, offering a more accessible entry point for some buyers. This would likely be a powerful V8, providing ample power for everyday driving and lighter-duty tasks. While it won't match the diesel's towing prowess, it would still deliver a strong performance and provide a more cost-effective alternative. The transmission is another critical component, and the 2025 AT4X AEV will undoubtedly feature a heavy-duty automatic transmission, expertly matched to the engine to maximize performance and efficiency. This transmission will likely offer multiple gears and advanced shift programming, optimizing power delivery in various driving conditions, from highway cruising to challenging off-road terrain. The AT4X trim already incorporates several performance-enhancing features, such as a lifted suspension and upgraded shock absorbers, which are designed to enhance off-road performance. The AEV collaboration amplifies these capabilities further by adding specialized equipment and modifications from American Expedition Vehicles. These can include upgraded wheels, tires, and underbody protection, improving the truck's ability to navigate rough terrain and protect vital components from damage.

This truck is built to handle the harshest environments. This combination of powerful engine options, a robust transmission, and specialized off-road components makes the 2025 GMC Sierra 2500HD AT4X AEV a force to be reckoned with. The exact specifications will be revealed closer to the launch date, but expect a truck that delivers unparalleled performance, both on and off the road, ensuring it can handle the toughest challenges with ease.
