Discover the 2025 GMC Sierra 1500 Interior

The 2025 GMC Sierra 1500’s interior combines craftsmanship, space, and utility across all trim levels. Whether you’re after the functional layout of the GMC Sierra 1500 Pro or the upscale finish of the Denali Ultimate, every detail is built with purpose.

The Sierra’s cabin sets the bar high with best-in-class front headroom and legroom in Crew Cab models. The driver-focused layout is filled with technology that supports work, travel, and everything in between.

Key Interior Features

The 2025 Sierra lineup delivers a wide range of features depending on the trim. Some of the best features include:

• Over 40 inches of combined digital displays — the most in its class
• Premium materials such as full-grain leather, open-pore wood, and patterned aluminum in upper trims
• Best-in-class front headroom and legroom in Crew Cab models
• Heated and ventilated front seats available on multiple trims
• Dual glove boxes, under-seat storage, and hidden seatback compartments
• Optional 16-way massaging power front seats with the Denali Ultimate and AT4X

From the base GMC Sierra 1500 Pro to the rugged AT4X, every model offers something that makes life easier on the road.

GMC Sierra 1500 Seats: Arrangement and Comfort

The 2025 GMC Sierra 1500 interior adapts to your needs, whether you’re commuting solo or carrying a full crew. Regular, Double, and Crew Cab configurations offer flexible setups for up to six passengers. If you opt for the Crew Cab, you’ll get best-in-class front headroom and legroom, giving you and your front passenger the space to stretch out.

Heated and ventilated seats are available, along with power-adjustable front bucket seats that include lumbar support. In the Denali Ultimate and AT4X, you can even add 16-way power seats with built-in massage. The rear seats feature optional hidden storage compartments and fold-up cushions, making it easier to carry cargo when the cabin is full.

Interior Design Details

Inside the 2025 GMC Sierra 1500, function and style come together without feeling forced. The design varies by trim, but across the board, it keeps a clean, practical look with just the right amount of polish. Materials feel durable and upscale, with every surface and stitch contributing to a sense of quality.

Higher trims, such as Denali and Denali Ultimate, feature genuine open-pore wood and patterned aluminum. Seating is finished in forge-perforated leather, and the Alpine Umber interior on the Denali Ultimate adds a deeper, richer tone to the cabin. For a sportier look, the AT4X mixes red double-needle stitching with ceramic white accents for extra contrast.

Even with its refined touches, the Sierra keeps things practical. You still get physical controls where they matter, including traditional GMC Sierra dash buttons that feel familiar and intuitive.

Technology and Connectivity

The technology inside the 2025 Sierra 1500 feels modern but grounded. You get a smart digital experience without sacrificing physical controls. Central to the setup is a 13.4-inch touch screen backed by a 12.3-inch digital driver display. On higher trims, you can also add a 15-inch head-up display that projects key info onto the windshield.

Google built-in integration brings voice control, maps, and a personal assistant directly into your dashboard. On Denali models and above, Super Cruise is available for hands-free driving, even while trailering. This system works across hundreds of thousands of miles of mapped roads.

The ProGrade Trailering System and myGMC app let you manage trailer profiles, check tire pressure, and manage departure checklists. It’s practical tech that actually helps on the job or the road.

Entertainment System

The sound system in the 2025 Sierra 1500 ranges from solid to full concert mode, depending on the trim level. Even base models deliver a crisp listening experience. If you choose the Denali Ultimate, you’ll get a 12-speaker Bose Premium Series system with Centerpoint surround sound, which turns the cabin into a sound studio.

Every trim includes wireless Apple CarPlay and Android Auto, making it quick and easy to sync your phone. Some models come with wireless charging built right into the center console. Between USB ports, Bluetooth, and an available Wi-Fi hot spot, your passengers stay connected without a mess of cords.

GMC Sierra 1500 Cargo Space

The 2025 GMC Sierra 1500 interior was built with smart storage in mind. In the Crew Cab, the rear seatback compartments are tucked behind the outboard seats, providing storage for items such as jumper cables, tie-down straps, or small tools.

Under the rear bench, a large storage area gives you room for bulkier items that you want to keep inside the cab and out of sight. The dual glove boxes in the dash — one upper, one lower with a lock — give you extra space for documents, devices, or valuables.

A wide center console between the front seats holds bigger essentials, such as laptops and tablets. Whether you’re on the road for work or heading out of town with family, this GMC truck delivers space that actually works.

Safety Features and Driver Aids

GMC Pro Safety comes standard across all trims. This package includes Automatic Emergency Braking, Lane Keep Assist with Lane Departure Warning, Forward Collision Alert, Front Pedestrian Braking, and a Following Distance Indicator. IntelliBeam headlights are also included, adjusting automatically based on lighting and traffic conditions.

Need help with tight parking or trailer connections? The available Front and Rear Park Assist is standard on higher trims. And for those who spend a lot of time trailering, the Transparent Trailer View and up to 14 available camera angles help you maneuver with confidence.

Higher trims offer advanced options, such as Super Cruise, which enables hands-free driving on compatible roads.
