The 2025 GMC Sierra HD is a towing powerhouse. The standard 6.6-liter V-8 gas engine delivers 401 horsepower and 464 lb-ft of torque, with a 10-speed automatic transmission. If you want maximum capability, the available turbocharged diesel 6.6-liter V-8 produces up to 470 horsepower and an impressive 975 lb-ft of torque.

Towing capacity reaches up to 36,000 lbs when properly equipped-perfect for serious work or heavy trailers. The truck also includes a trailer-brake controller (now standard across all models on 2025+), and advanced trims add adaptive cruise control with trailering assist and up to 15 camera views, including a transparent trailer mode.
