What is the difference between 2024 Sierra 1500 AT4 and Denali?

The biggest difference is price. But when looking at the two trims, the AT4 comes with a slightly less powerful engine. If you’re not needing something powerful, then the extra price point that the Denali comes with isn’t worth it. Automatic Emergency Braking comes standard on the AT4, but not the Denali. This not only makes the AT4 safer, but also more appealing if you’re wanting something more than just a truck.
The AT4 also comes with premium front and rear floor liners with removable carpet insert, making it not only nice, but easy to clean.
How many miles per gallon does a 2024 GMC AT4 get?

When looking at the 3.0L Duramax that the Sierra 1500 AT4 comes standard with, you can expect 22 mpg combined. This breaks down to 21 city miles, and 23 highway miles. These numbers are really close to each other, giving it a pretty uniform range you can plan on.
The gas tank is 24-gallons. When putting the numbers from the mileage into the equation, you can go at least 504 city miles, and 552 highway miles. While having decent mileage, it also has a pretty good max tow capacity. Thanks to the 305 horsepower, and 495 lb-ft of torque, you can tow 8,900 pounds. The max payload capacity is also commendable which sits at 1,620 pounds. No matter what job is in front of you, the AT4 can do it with ease.
What's so special about the AT4?
The AT4 trim on the GMC Sierra 1500 takes the best features possible, and puts it into an affordable package.
The AT4 starts at $68,395, coming with a tailgate that has EZ lift assist as well as power lock and release. These work together to make sure that you never have to use more force than you have to when you need to access the bed of the truck. The bumper also comes with a CornerStep rear bumper, this makes it easy to get into the bed.
The interior of the AT4 is just as nice. When inside you can expect a 13.4-inch GMC premium infotainment system. This has wireless phone connectivity, and voice activated features that help you maintain focus on the road while still able to change the station, and access navigation.
Both the front two seats come with 10-way power seats, with lumbar support. The comfort doesn’t stop there! The first two seats are also heated and ventilated, while the rear outboard seats also gain heating features.
When going to and from sites, the remote start function, and keyless open, the Sierra 1500 will make sure that it’s easy to get in and go. When inside, the truck also comes with some helpful features. You can charge your phone wirelessly, making it easy to get in, set your phone down, and never have to worry that it won’t be charged again.
