Overview of the Duramax engine in the GMC Sierra 1500 AT4X 2024

September 04 2023 -

The GMC Sierra 1500 2024 has caused quite a stir with its many upgrades and new versions, including the powerful AT4X model. However, a new option was quietly added in April: the legendary Duramax turbodiesel engine, which also received its share of updates this year. The Duramax is the perfect complement to the AT4X's robustness and performance. Let's take a look at what this combination has to offer.

Duramax 3.0L Turbodiesel engine: More power, more torque

First introduced in selected Sierra 1500 models in 2023, the updated Duramax engine comes with a 10-speed automatic transmission and offers a maximum output of 305 hp, a 10% increase over the 2022 model year. Maximum torque is equally impressive, reaching 495 lb-ft, up 7.6% on the previous year.

Technical innovations

This increase in performance is due to several key improvements:

- New steel pistons with revised combustion chamber

- Recalibrated turbo compressor

- New fuel injectors

- Improved temperature control features

What sets the Duramax engine apart in the GMC Sierra 1500 AT4X 2024?

Obviously, we're talking about power here. We've already talked numbers, but did you know that the AT4X Duramax offers the best power and more torque than any other diesel-powered truck in the segment? What's more, its active thermal management function gives the Duramax the best efficiency ever for a diesel engine. AT4X owners therefore benefit from an exceptional combination of power, performance, efficiency and towing capacity.

In addition to towing 8,800 lbs, the Duramax helps the AT4X's off-road performance. The latter benefits from maximum torque at low revs, making it easy to traverse the toughest trails. When you're driving off-road, torque is the most important thing. With 495 lb-ft of torque, the Duramax has torque in abundance at all times. What's more, the 10-speed gearbox helps enormously in managing torque in an affordable way.

The 2024 GMC Sierra 1500 AT4X with its Duramax engine option represents a powerful combination of ruggedness and performance. Whether you're looking to tow heavy loads or explore challenging terrain, this new option should be on your shortlist. Duramax brings not only more power and torque, but also proven reliability, making the Sierra 1500 AT4X 2024 one of the strongest choices for those seeking both power and versatility.
