When you think of a big, powerful truck, you probably think of a diesel engine. And when it comes to diesel engines, GM’s Duramax is often considered the leader. Available as an option on the Chevrolet Silverado HD and 2024 GMC Sierra HD, the Duramax offers not only phenomenal torque, but also the towing capacity that comes with it and that you want in your next truck. If you’re looking for a rugged pickup that delivers exceptional performance, the Chevrolet Silverado HD and 2024 GMC Sierra HD duo should be on your list, especially with the Duramax diesel engine. In the following text, we take a look at what sets this unique engine apart.
Performance and efficiency
The Duramax 6.6L turbodiesel engine has been upgraded for 2024. The engineering team behind the Silverado HD and Sierra HD have managed to push the boundaries, increasing power to an impressive 470bhp and torque to an astonishing 975lb ft, as certified by SAE J1349. These advances are not limited to simply higher figures; meticulous modifications have been made to achieve a more efficient combustion process, amplifying the engine’s overall performance. In addition, the engine’s low-speed torque output has been increased by up to 25%, ensuring superior performance when manoeuvring at low speeds, climbing hills, and especially when towing. This combination of power, torque and efficiency makes the Duramax turbo-diesel engine a true leader in its class. The Duramax V8 diesel engine is mated to a ten-speed Allison transmission.
Towing capacity
Thanks to its even greater torque, the Duramax engine is impressive when it’s time to tow – an ultra-important feature for many heavy truck users.
The maximum towing capacity of the 2024 Silverado HD and 2024 Sierra HD obviously depends on the model and configuration. That said, the Duramax outperforms the standard 6.6-litre V8 and the majority of its rivals when it comes to towing capacity. Here’s an overview of what each version of the two trucks can tow in terms of maximum load.
| Model | Maximum towing capacity 2WD | Maximum towing capacity 4WD |

Reliability and durability
Duramax engines are built with robust materials and are designed to last. They are capable of withstanding the demands of tough driving and heavy loads. They also have a reputation for longevity with regular maintenance.
Driving comfort
Despite their size and power, trucks powered by Duramax engines are also known for their relatively smooth ride and low noise levels, especially when compared to other diesel vehicles in this class. Power delivery is linear and predictable, and the engine doesn’t rumble when called upon. It’s a really smooth engine that’s even refined when used on a daily basis.
