The 2026 Sierra 1500 gives you a strong lineup of powertrain options tailored to fit your needs. The standard TurboMax engine produces 310 horsepower and a best-in-class 430 pound-feet of torque, giving you serious muscle right from the base trim. Step up to the available 5.3-liter V8 or the 6.2-liter V8 for even more capability, or go with the available Duramax 3.0-liter Turbo-Diesel for maximum efficiency combined with a towing capacity of up to 13,300 pounds when properly equipped.
