GMC calls the 2027 Sierra 1500's interior its most immersive truck cabin yet, and GMC advertises a 16.3-inch center screen, a 12.2-inch driver display and an available 11.5-inch passenger screen. Its more-than-60-inch combined-display claim for Denali Ultimate additionally includes other displays, such as the Head-Up Display and Rear Camera Mirror. Our checklist on seat types and configurations for car seat covers is a good starting point before getting into the redesign details below. GMC identifies the 2027 model as a next-generation Sierra 1500 with six announced trims: Pro, Elevation, AT4, AT4X, Denali and Denali Ultimate.
New Features In the All-New 2027 GMC Sierra 1500's Cabin
GMC describes the 2027 Sierra 1500 as its next-generation truck, with redesigned styling, cabin technology and seating features.
Best-in-Class Head and Leg Room Comes Standard on Every 2027 GMC Sierra Trim
Every 2027 GMC Sierra trim, including the entry-level Sierra Pro, gets best-in-class standard crew cab front head and leg room, a confirmed spec that applies across the board rather than being reserved for higher trims. Our guide on car seat cover material types gets into how eco-leather works across a cabin this size, regardless of which Sierra trim you're protecting.
The 2027 GMC Sierra's Articulating Touchscreen Hides a Storage Compartment
GMC confirms a standard 16.3-inch center touchscreen even on the entry Pro. Elevation and Denali Ultimate additionally include an articulating 16.3-inch version with hidden storage as standard. That's a technology detail rather than a seat feature, but it signals how thoroughly GMC redesigned this cabin from the ground up rather than layering new tech onto the old structure.
Seat Materials Across All 2027 GMC Sierra Trims
GMC has confirmed six 2027 Sierra trims, and the seat materials and features available change meaningfully as you move up the lineup; exact material and equipment details should be checked against GMC's published specifications for each trim.
2027 GMC Sierra Pro, Sierra Elevation, and Sierra AT4: The Confirmed Foundation
The Sierra Pro sits as the work-focused entry point, with the Sierra Elevation adding more everyday comfort features on top of it. The Sierra AT4 carries the off-road identity forward from the outgoing generation. Consult GMC's published specifications for Sierra Pro upholstery; the redesigned cabin architecture and standard head and leg room improvements apply to it the same as every other trim. Our guide on seat cover installation for trucks has more on what to check for a work-focused trim like this. Our blog on why eco-leather is the best seat cover material rounds out why this material holds up well across the entire lineup.
2027 GMC Sierra AT4X: Enhanced Bolstering and a Sierra-First Tire
The Sierra AT4X gets an exclusive Timber Mahogany interior colorway and available carbon-fiber interior accents, a sport flat-bottom steering wheel, and enhanced front-seat bolstering built with off-road driving in mind. It also rides on 35-inch mud-terrain tires, paired with front and rear electronic locking differentials. Our blog on the benefits of dustproof seat covers for desert areas is worth reading if you actually take the Sierra AT4X off-road.
2027 GMC Sierra Denali and Sierra Denali Ultimate: Premium Seating and Wood
The Sierra Denali and Sierra Denali Ultimate move into genuinely luxury territory, with upscale upholstery and distinctive interior materials; check GMC's specifications for the exact leather grade and seating surfaces on each trim. The Sierra Denali Ultimate alone adds forged wood trim standard, and a panoramic sunroof is standard on both AT4X and Denali Ultimate. Our post on protecting leather seats from everyday wear applies directly to these interior materials.
A full front-and-rear eco-leather set from our team costs $389 and includes 2 front seat covers, 2 headrest covers, and 1 rear bench seat cover, covering all 5 seats, backed by a 3-year warranty. Our guide on how seat covers affect vehicle resale value is a good companion read for owners planning to keep their Sierra long-term. Front-seat-only coverage runs $279 separately for owners who mainly want the front seats protected. Our team builds OEM-style GMC Sierra seat covers around this exact redesigned seat architecture.
Conclusion
The 2027 Sierra 1500 brings a genuinely new cabin, not a styling update layered onto the old truck. Every trim gets best-in-class head and leg room and the redesigned architecture underneath it, while the Sierra AT4X's enhanced bolstering and the Sierra Denali Ultimate's premium interior materials show just how far the range spreads from work truck to luxury vehicle. Whichever trim you end up with, protecting a cabin this new means matching the pattern to the actual redesigned seat, not assuming last generation's cover still fits. Our comparison of affordable versus high-end seat covers is a useful read too if price is part of your decision.
