2025 GMC Sierra 3500 Overview

The 2025 GMC Sierra 3500 forms part of the brand's heavy-duty truck lineup. Available in both RWD and 4WD versions, this robust pick-up offers two potent powertrains: the base 6.6L Gas V8 with a 6-speed automatic transmission, and the Duramax Turbo-Diesel 6.6L V8, paired with a robust Allison 10-speed automatic, capable of producing impressive torque. The Sierra 3500 provides multiple trims starting from the work-ready base to the range-topping Denali, each with unique amenities and styling. Key safety features include an array of driver assists such as automatic emergency braking and lane assist, while its infotainment system readily accommodates Apple CarPlay, Android Auto and a Wi-Fi hotspot. For 2025, the MultiPro tailgate, providing six different functions and positions for increased versatility, is a noteworthy addition. The model's exceptional durability and towing capacity make it an attractive choice in the trend of high-performing pick-ups.
