When this generation hit the roads, it brought some pretty decent power. Coming with a pair of engines, there's the 6.0L V8 and the 6.6L V8 Diesel engine. This gives drivers an easy way to get what they're looking for. For those who want the most towing power, you'll want to look for something that is powered by a gas engine. This is because it comes with a massive tow rating of 18,500 pounds. This is a monster rating, making it easy to tow just about everything that you need it to.
While that is with the gas engine, the diesel does come with something up its sleeve. This is the above-average fuel efficiency. While not officially tested by the EPA, given the nature of the model, Car and Driver did note that the diesel model is able to get 17 MPG combined, and when towing long distances, you'll find that this is the best option for those who want to save a bit at the pump.
Moving to the interior, you'll find that this model comes with some great features, and even some class-exclusive ones that help it stand out. For the one that you can only find on the Sierra, you can look for a model that is equipped with a head-up display. This makes it so that you won't need to take your eyes off the road to view your truck's speed. For other features, you'll find a heated steering wheel, heated and cooled front seats, and wireless charging.
Starting on 2021 models, you'll find that these are a bit safer when it comes to doing some heavy towing. This takes the form of a jack-knife alert. When operating with a trailer in tow, if things start to get a bit squirrely, you'll know before it's too late. These models also come with a trailer length indicator, making sure that you're confident when parking, as well as driving.
With the 2024 models, these are the best for those who want luxury. With the addition of the Denali Ultimate trim, you'll find that it adds leather-wrapped door panels, steering wheel, and A- and B-pillar handles. The 16-way power-adjustable front heated and cooled massage front seats also have intricate leather stitching. This makes it so that when you and other people get in the truck, they'll know that it's more than just a work truck.
Over the next couple of years, the model saw some changes, but nothing too much that would make or break getting one from this generation. If you want adaptive cruise control with trailering assist, then you're in luck, as the availability was expanded in 2025. If you want the trailer brake control, then this is also the year model to get, as it is now standard across all trims.
