Whether towing heavy loads or navigating challenging terrains, the Sierra delivers the tools and features to make the job easier and more enjoyable.
The 2025 GMC Sierra offers a comprehensive selection of engines, catering to varying levels of performance and efficiency. The entry-level TurboMax™ engine, available on trims like the Pro, combines impressive torque with fuel efficiency. This 2.7L turbocharged engine delivers 310 horsepower and 430 lb.-ft. of torque, making it ideal for light-duty towing and everyday driving. Its advanced combustion process and air cooling systems ensure reliability and consistent performance, even in extreme conditions.
For those requiring more power, the available 5.3L V8 engine produces 355 horsepower and 383 lb.-ft. of torque, capable of towing up to 11,200 pounds. Meanwhile, the 6.2L V8 engine, standard on the Denali Ultimate and available on several other trims, offers a robust 420 horsepower and 460 lb.-ft. of torque. This engine supports a maximum towing capacity of 13,000 pounds, making it a go-to choice for heavy-duty applications. Diesel enthusiasts can opt for the Duramax 3.0L Turbo-Diesel engine, which provides 305 horsepower and an impressive 495 lb.-ft. of torque. With a towing capacity of up to 13,200 pounds, the Duramax offers exceptional efficiency and low-end power for extended hauls.
Towing capabilities are a cornerstone of the Sierra's appeal, with each engine tailored for specific trailering needs. At the entry level, the TurboMax™ engine supports a respectable towing capacity, making it suitable for smaller trailers and recreational equipment. Moving up, the 5.3L V8 enhances capability with a maximum towing capacity of 11,200 pounds, perfect for larger trailers or mid-sized boats.
For those who demand the ultimate towing power, the 6.2L V8 and Duramax Turbo-Diesel engines deliver outstanding performance.

Meanwhile, the Duramax engine not only achieves a 13,200-pound towing maximum but also incorporates Active Thermal Management and a variable-geometry turbocharger, ensuring optimal performance and cooling during demanding tasks.
The Sierra enhances its towing prowess with a suite of advanced technologies that streamline the trailering experience. The ProGrade® Trailering System integrates tools like a trailer light test, trailer theft detection, and trailer tire pressure monitoring, allowing drivers to manage their trailer setup with confidence. Up to 14 camera views, including Hitch Guidance with Hitch View, assist in precise maneuvering and hitch alignment, even in tight spaces.
Super Cruise™, available on higher trims like the Denali Ultimate, takes towing convenience to the next level with hands-free driving on compatible highways. This system allows drivers to focus on monitoring the road while the truck maintains lane position and speed, even while towing. Combined with the MultiPro™ Tailgate, which offers six distinct functions for easier loading and unloading, the Sierra ensures every towing job is executed with efficiency and ease.
Despite its impressive capability, the Sierra prioritizes driver and passenger comfort. Its spacious Crew Cab provides ample headroom and legroom, ensuring a pleasant ride for long hauls. Premium materials, such as open-pore wood and perforated leather in the Denali trims, add a touch of luxury. Features like heated and ventilated seats and a quiet cabin further enhance the driving experience.
For drivers who tow frequently, the available adaptive ride control and precision steering ensure a smooth and stable journey. These features work in tandem with the truck's robust suspension to minimize vibrations and maintain control, even under heavy loads.
