GMC has unveiled the next-generation 2027 Sierra 1500, introducing extensive updates to its design, technology, and luxury features. Leading the lineup is the Sierra Denali Ultimate, the highest-specification trim of GMC’s full-size pickup.

The 2027 Sierra Denali Ultimate combines a new 6.6-liter V8 engine producing 481 horsepower and 501 lb-ft of torque, equivalent to approximately 679 Nm, with a 10-speed automatic transmission. It also features an advanced digital cabin with more than 60 inches of combined displays, along with Super Cruise hands-free driving on compatible roads and trailer support.

New 481-HP V8 Engine

The Denali Ultimate comes standard with a new-generation 6.6-liter V8, naturally aspirated engine producing 481 horsepower at 5,800 rpm and 501 lb-ft of torque at 4,000 rpm, equivalent to approximately 679 Nm.

GMC says the engine is the most powerful naturally aspirated V8 in its class, as well as the largest-displacement V8 in its class and the most powerful half-ton V8 in GMC history.

The engine is paired exclusively with a 10-speed automatic transmission across the 2027 Sierra lineup.

It also receives several upgrades, including a higher compression ratio, a larger throttle body, an improved intake manifold, and a dual-injection system combining direct and port injection.

3.0-Liter Duramax Diesel Also Available

Alongside the V8, GMC offers the 3.0-liter six-cylinder turbocharged Duramax diesel in the Sierra Denali Ultimate.

The diesel produces 305 horsepower and 495 lb-ft of torque, equivalent to approximately 671 Nm, and is paired with the same 10-speed automatic transmission.

When equipped with the optional fuel tank with a capacity of approximately 34 gallons, GMC estimates that the truck can achieve more than 900 miles, or around 1,450 kilometers, of highway driving range.

Digital Cabin With More Than 60 Inches of Displays

One of the highlights of the new Sierra Denali Ultimate is its technology-focused interior, featuring more than 60 inches of combined digital displays.

Standard equipment includes:

16.3-inch central display with a movable design and hidden storage space behind it.

11.5-inch front passenger display with a movable privacy cover designed to prevent the driver from viewing content intended for the passenger.

12.2-inch digital instrument cluster with multiple display layouts.

15-inch multicolor Head-Up Display.

GMC says the 16.3-inch infotainment display is the largest in its class, while the 11.5-inch passenger display is also the largest in its segment according to the company.

Massaging Front Seats and Premium Features

The Denali Ultimate also places a strong focus on luxury, with 14-way power-adjustable front seats featuring heating, ventilation, and massage functions.

The cabin also features a premium 16-speaker Bose sound system, including speakers integrated into the front headrests, along with open-pore birch wood trim, dynamic ambient lighting, and a panoramic roof.

GMC also adds dual wireless charging with MagSafe compatibility and a new MultiPro Center Console that combines additional storage with an expanded work surface.

Super Cruise With Hands-Free Driving and Trailer Support

Super Cruise comes standard on the Denali Ultimate, allowing hands-free driving on compatible roads while also supporting trailer towing.

The system can control steering, acceleration, and braking when operating conditions are met and on supported roads. Equipped versions can also offer features such as automatic lane changes and lane changes activated through the turn signal.

However, GMC emphasizes that Super Cruise is a driver-assistance technology, not a fully autonomous driving system. The driver must continue monitoring the road and remain ready to take control when necessary.

Up to 19 Camera Views

One of the Sierra Denali Ultimate’s key technology features is an advanced camera system that provides up to 19 different views rather than necessarily using 19 separate cameras.

The system includes a rear camera mirror, interior view, trailer hitch view, transparent trailer view, and front and rear underbody camera views.

The underbody cameras also feature a dedicated cleaning system to help maintain image clarity.

22-Inch Wheels and Distinctive Denali Ultimate Design

The Sierra Denali Ultimate is equipped with 22-inch aluminum wheels featuring a hexagonal design and Diamond-Cut finish, along with exclusive exterior elements.

The truck also features a premium Denali grille, GMC signature lighting, distinctive exterior trim, and MultiPro Power Steps that make access to the cabin and cargo bed easier.

Adaptive Suspension System

The Denali Ultimate uses Adaptive Ride Control, combined with an independent front suspension and a solid rear axle.

The system is designed to improve ride comfort and stability while maintaining the capabilities required for everyday use and towing.

Sierra 2027 Gets a New Infotainment System

Beyond the range-topping trim, the entire 2027 Sierra lineup receives a major update to its digital user interface.

GMC’s new interface is designed to provide easier access to navigation, vehicle status, media, trailer information, and Super Cruise functions.

It also supports Google built-in, including Google Maps, Google Play, and Google Gemini, alongside Apple CarPlay and Android Auto.

Over-the-air software updates and 5G connectivity are also available on appropriately equipped vehicles.

Improvements to the Cargo Bed

The 2027 Sierra’s cargo bed also receives several practical upgrades, including a revised MultiPro Tailgate, four additional tie-down points, and an integrated measuring system.

According to GMC, the cargo bed provides 16 standard tie-down points and offers class-leading cargo capability.

Towing Capacity

Across the new Sierra 1500 lineup, towing capacity varies depending on the engine, equipment, and drivetrain configuration.

With the 6.6-liter V8, the currently published maximum towing capacity for a Crew Cab 4WD configuration is approximately 9,400 pounds, or around 4,264 kg.

With the 3.0-liter Duramax diesel, maximum towing capacity can reach 12,100 pounds, or approximately 5,488 kg, when properly equipped with the appropriate configuration and NHT package.

2027 GMC Sierra Denali Ultimate Pricing

GMC has announced a starting price of $87,895 for the 2027 Sierra Denali Ultimate, including destination and delivery charges in the United States.

Meanwhile, GMC’s consumer website lists a base price starting at $85,100 before destination charges.

The final price varies depending on the cab and bed configuration, drivetrain, engine, and optional equipment.

This pricing does not represent the vehicle’s price in Jordan, as local pricing will vary depending on the dealer, market, taxes, fees, and local specifications.

When Will the 2027 GMC Sierra Reach the Market?

GMC expects the first 2027 Sierra 1500 models to reach U.S. dealerships before the end of 2026, with additional configurations becoming available gradually.
