GMC Sierra Diesel: MPG, Warranty, Reliability, & More

Diesel-powered vehicles have been around since the 1920s and have stood the test of time. GMC has made its mark in history too with its revolutionary Duramax engine, which came into existence in 2001 in some early GMC trucks. The Duramax engine is a V8 that is produced by DMAX, a subsidiary of General Motors. Since 2001, this efficient yet powerful engine has been placed in numerous vehicles, ranging from vans to various sizes of trucks.

Diesel Truck Advantages

There are numerous benefits to owning a diesel-fueled truck, as opposed to a traditional gas-powered truck. First and foremost, diesel-powered trucks like the GMC Sierra, are considerably more efficient in regards to fuel efficiency and range. Diesel trucks generally will get both more mpg than gas trucks as well as an increased fuel range, which is crucial to buyers who intend to use the truck to commute long distances. Diesel trucks also offer increased performance, since the turbocharged nature of the engines creates more low-end power which is important for towing. This increased low-end torque allows increased towing capacity. To handle the increase in power, diesel engines are often reinforced when being engineered and produced, which allows them to last a lot longer than traditional motors, in some cases, twice as long. The 2024 GMC Sierra, equipped with the Duramax diesel motor, checks all of these boxes and is an excellent choice for all sorts of buyers in the Minneapolis area.

As alluded to above, the Sierra diesel is an excellent option if you are looking for a truck with enhanced capability and utility, while retaining the creature comforts that make GMC such a stand-out player in its segment.

Sierra 1500 Turbo Diesel

The Sierra 1500 diesel is a truly exceptional choice for buyers who want the added benefits of a diesel truck, while also retaining the same body size as a traditional gas-powered Sierra.

It is also a more liveable option as it is not as wide and long as some of the heavy-duty Sierra trucks.

Sierra 2500 & 3500 Turbo Diesel

The Sierra 2500 and Sierra 3500 trucks are the heavy-duty end of the Sierra lineup, offering the most durability and utility thanks to their build construction and powerful engines.
