The 2024 GMC Sierra 2500 HD is a powerful and impressive heavy-duty pickup truck capable of towing heavy loads. Could this truck be your next big work tool?
This big and powerful GMC truck could have received a mid-cycle refresh for 2023, but instead, that refresh takes place with the 2024 mode. The upgrades added make the Sierra 2500 HD more capable and impressive than ever before, ensuring this truck has the power to handle heavy loads and tackle the toughest jobs.
Two excellent powertrains for this big pickup
The base powertrain for the GMC Sierra 2500 HD is a 6.6-liter V8 engine powered by gasoline. This engine mates to a ten-speed automatic transmission, enabling smooth shifting and an impressive power delivery to the wheels. The base setup returns 401 horsepower and 464 lb-ft of torque while delivering a max towing capacity of 18,500 pounds and a max payload of 3,395 pounds.
If you want more power and pulling figures, the 6.6-liter turbocharged Duramax diesel V8 engine gives you the power you want for your drive. This impressive diesel engine also uses a ten-speed automatic transmission but delivers 470 horsepower and 975 lb-ft of torque. In the 2024 GMC Sierra 2500 HD, this powertrain returns a max towing capacity of 22,500 pounds and up to 3,850 pounds of payload.
Is there anything new for this pickup truck?
The 2024 version of the three-quarter-ton heavy-duty GMC pickup gives you some impressive changes. The trim lineup gains the Denali Ultimate at the top level, while new interior colors are available across the board. Rain-sensing wipers are now standard, starting at the SLT trim, while a 13.4-inch infotainment screen is part of every model except the Pro trim. All models also enjoy the benefits of the Pro Safety package.
