The 2024 GMC Sierra 3500 HD offers two powerful engine choices:

**Standard Gas Engine:** 6.6L V-8 with 401 horsepower and 464 pound-feet of torque, paired with a 10-speed automatic transmission.

**Optional Duramax Diesel:** 6.6L turbocharged V-8 producing 470 horsepower and an impressive 975 pound-feet of torque, also with a 10-speed automatic (Allison-certified) transmission.

Both engines deliver a refined, responsive driving experience. The Duramax diesel is ideal if you regularly tow heavy loads and need maximum pulling power. The Sierra 3500 HD is available in rear-wheel or four-wheel drive, and you can choose a single or dual-rear-wheel axle configuration.
