2024 GMC Sierra 1500: What's New, Specs & Features
Last updated August 4, 2026
The biggest 2024 Sierra 1500 change is in AT4X: its 3.0L Duramax turbo-diesel becomes standard, while the 6.2L V8 shifts to the alternate engine. The rest is a modest update rather than a redesign.
About the 2024 GMC Sierra 1500
4th generation (2019-present), third model year after the 2022 mid-cycle update
GMC positions the Sierra 1500 as a full-size pickup that combines serious towing, hauling and bed utility with a more premium cabin than a basic work truck. Its broad cab, bed, engine and drivetrain range serves jobs, family use, towing and recreation. The MultiPro tailgate, diesel availability, off-road AT4 models and luxury-focused Denali models distinguish it from more narrowly focused competitors.
For 2024, GMC positions the Sierra lineup to cover straightforward work duty, everyday comfort, off-road use and luxury. Pro is the basic work truck, while AT4 adds a 2-inch lift and off-road hardware; AT4X goes further with locking differentials at both axles and massaging front seats. Denali emphasizes comfort with perforated leather, real wood trim and a suspension that adjusts to road conditions.
