2027 GMC Sierra Denali
By Lorenzo Bianchi September 23, 2026
A new 5.7-liter Small Block V8 producing 402 hp and 428 lb-ft is standard on the Sierra Denali.
Denali combines a signature chrome grille with three available interior colorways and birch wood accents.
The 4WD Crew Cab starts at $76,795 including the $2,795 destination freight charge.
The 2027 GMC Sierra Denali arrives as part of the next-generation Sierra 1500 range, bringing a new V8, redesigned exterior and a cabin with more display technology. Denali remains positioned above AT4 and below Denali Ultimate, keeping its focus on luxury without moving all the way into the flagship's equipment level.
GMC has also expanded the technology fitted as standard. Super Cruise with trailering capability is now included on Denali, while a broader group of driver assistance systems is standard across the 2027 Sierra lineup.
Chrome Grille Leads A More Upright Design
The new Sierra adopts a more vertical grille and machine-precision body forms. Its lighting has also changed, with 7-shaped headlamps and taillamps defining the front and rear. Welcome and farewell lighting animations, illuminated GMC signature lighting and quad exhaust outlets are available across the wider range.
Denali is visually separated by its signature chrome grille. The overall approach keeps the familiar full-size pickup proportions while giving the nose a more upright appearance.
Practical details haven't been overlooked. The available MultiPro Tailgate gains a redesigned applique, four additional tie-downs and an integrated ruler, while the bed provides 16 standard tie-down locations.
Three Interior Colorways Join Birch Wood Trim
The Denali cabin can be specified in three color combinations: After Dark/Sheer with Sapphire Blue accents, Terra Summit with Bright White accents, or Twilight Harbor with Bright White accents. Birch wood accents and Denali-branded seating further separate it from other Sierra trims.
Standard front seats provide 12-way power adjustment with heating and ventilation. A panoramic sunroof, Head-Up Display and Rear Camera Mirror are also included.
The dashboard combines a 16.3-inch infotainment touchscreen with a 12.2-inch Driver Information Center. GMC's new interface integrates Apple CarPlay and Android Auto alongside Google built-in services, including Google Maps, Google Play and Gemini.
An available Technology Package adds an 11.5-inch passenger display with an articulating cover. Denali also gets an eight-speaker Bose system, dynamic ambient lighting, the MultiPro center console and dual MagSafe wireless chargers.
New 5.7 Liter V8 Produces 402 HP
Under the hood, the standard engine is GMC's new sixth-generation 5.7-liter Small Block V8. It produces 402 hp and 428 lb-ft and is paired with a 10-speed automatic transmission.
Buyers can move up to the new 6.6-liter V8, rated at 481 hp and 501 lb-ft, or choose the available 3.0-liter Duramax turbo-diesel with 305 hp and 495 lb-ft. An approximately 34-gallon fuel tank is also available.
At $76,795 for the 4WD Crew Cab, Denali sits $11,100 below the $87,895 Denali Ultimate while retaining the Sierra's new V8, premium cabin treatment and standard Super Cruise.
