GMC Sierra 1500 2024: More torque for the diesel engine

The 2024 model year is starting to unveil little by little at General Motors, and it's now the turn of the GMC Sierra 1500 2024 to benefit from several upgrades for this new year/model. The AT4X version will now be available with the diesel engine, which has been improved for the occasion.

 

• A new 3.0-liter diesel engine with 277 horsepower and 495 pound-feet of torque for the 2024 GMC Sierra AT4X.

• The Duramax engine becomes the entry-level powertrain for the AT4X version.

• Two new colors for the 2024 Sierra 1500.

 

Just like the Chevrolet Silverado 1500 ZR2 2024, the GMC Sierra 1500 AT4X 2024, which is the ultimate version of the model, offers the 3.0-liter Duramax turbo-diesel engine. The small engine, which serves as the entry-level powertrain, has a power output of 277 horsepower, which remains unchanged from what is found in the other models. However, the torque output increases from 460 pound-feet to 495 pound-feet, which is a considerable increase. It's quite impressive when comparing these figures to those of the 6.2-liter V8 engine that produces 420 horsepower and 460 pound-feet of torque.

 

The addition of the diesel engine to the GMC Sierra AT4X lineup expands the target audience of this version to those with increased off-road capabilities. The way the diesel engine delivers its power is quite different from that of the 6.2-liter V8, and I won't hide the fact that this can have a major impact on low-speed driving or when torque output greatly outweighs power.

 

This is an engine that is likely to be of great interest to off-road enthusiasts and also those who love the design of the Sierra 1500 AT4X but were hesitant to purchase the model because it was too fuel-thirsty. Although the figures have not yet been unveiled, it is certainly expected that the 3.0-liter Duramax diesel engine will be significantly more fuel-efficient than the 6.2-liter V8, even if the price of diesel is currently higher than that of gasoline.

 

I had the chance to test both powertrains in several General Motors products over the past year, and I can tell you that there's something for everyone here. The 6.2-liter V8 engine offers a very different behavior from the 3.0-liter engine, even though their technical specifications are similar. In my opinion, it's an excellent decision on the part of General Motors to offer the diesel engine for the ultimate version of the Sierra and the same goes for the Silverado. This strategy allows General Motors to distinguish itself from the competition between the RAM 1500 TRX and the Ford F-150 Raptor, where all that seems to matter is the number of horsepower under the hood.

 

Other Improvements

 

Without giving us too many details, General Motors mentions that there are several small updates for the other versions of the GMC Sierra 1500 2024, including the addition of two new colors and the availability of an active exhaust system for some of them.
