2027 GMC Sierra 1500 Engines and Powertrains

The 2027 Sierra 1500 offers four engines covering work-focused gasoline, diesel, trailering, off-road, and premium applications.

Enhanced 2.7L TurboMax

The TurboMax remains the standard engine in the Sierra Pro and Elevation. For 2027, output increases to 350 hp at 5,200 rpm and 455 lb.-ft. of torque at 3,000 rpm. GMC says that represents an increase of 40 hp and 25 lb.-ft. compared with the previous version.

Updates include a new turbocharger, upgraded fuel injection, improved active thermal management, and redesigned pistons.

The aluminum-block engine uses dual overhead camshafts, four valves per cylinder, continuously variable valve timing, variable valve lift, Active Fuel Management, and direct injection.

New 5.7L V-8

The new sixth-generation 5.7L V-8 produces 402 hp at 5,500 rpm and 428 lb.-ft. of torque at 4,300 rpm. The engine uses an aluminum block and cylinder heads, overhead valves, two valves per cylinder, variable valve timing, and a dual-fuel system combining direct and port injection.

When properly equipped, Sierra configurations using the 5.7L V-8 can tow up to 13,500 pounds.

New 6.6L V-8

The new 6.6L V-8 becomes the most powerful engine in the 2027 Sierra 1500 lineup. It produces 481 hp at 5,800 rpm and 501 lb.-ft. of torque at 4,000 rpm.

Like the 5.7L, the 6.6L uses direct and port fuel injection, variable valve timing, aluminum construction, and an overhead-valve design.

The 6.6L is standard on Denali Ultimate and available on AT4X and Denali.

3.0L Duramax Turbo-Diesel

The 3.0L Duramax Turbo-Diesel continues for 2027 with 305 hp at 3,750 rpm and 495 lb.-ft. of torque at 2,750 rpm. The inline diesel uses dual overhead camshafts, four valves per cylinder, direct injection, and an aluminum block with cast-iron cylinder liners.

With the available approximately 34-gallon fuel tank, GMC estimates more than 900 miles of highway driving range.

Every 2027 Sierra 1500 engine is paired with a 10-speed automatic transmission. Sierra models equipped with the TurboMax use a 3.42 axle ratio. The 5.7L V-8, 6.6L V-8, and 3.0L Duramax use a 3.23 axle ratio.

2027 GMC Sierra 1500 Lineup

GMC offers six Sierra 1500 trims for 2027:

• Pro
• Elevation
• AT4
• AT4X
• Denali
• Denali Ultimate

The lineup moves from a work-focused fleet truck through premium, off-road, and luxury configurations.

Sierra Pro

Pro is the primary commercial and work-focused Sierra configuration. The enhanced TurboMax is standard, along with the 10-speed automatic transmission, 12.2-inch Driver Information Center, 16.3-inch center infotainment screen, trailer hitch, trailer brake controller, high-capacity air cleaner, manual tilt-and-telescoping steering wheel, and expanded standard safety equipment.

The 5.7L V-8 and 3.0L Duramax Turbo-Diesel are available. GMC also plans multiple cab and box configurations, a Graphite Package, and work-focused accessories.

Sierra Elevation

Elevation starts with the TurboMax and adds more comfort and technology. Standard equipment includes bucket seats and a dedicated center console, articulating 16.3-inch infotainment display with hidden storage, MultiPro Tailgate, MultiPro center console with workstation, dual wireless charging, 120-volt outlets, power-sliding rear window, and applicable X31 off-road equipment.

The 5.7L V-8 and 3.0L Duramax are available, along with the Max Trailering Package, Trailer Technology Package, Super Cruise Package, 34-gallon fuel tank, and other equipment.

Sierra AT4

AT4 combines premium equipment with additional off-road capability. The 5.7L V-8 is standard, along with a 2-inch factory lift, monotube shocks, 34-inch all-terrain tires, Super Cruise with trailering capability, panoramic sunroof, Head-Up Display, heated and ventilated front seats, and MultiPro center console.

The Duramax diesel is available.

Sierra AT4X

AT4X becomes the most off-road-focused Sierra 1500. The Duramax diesel is standard, along with a 34-gallon fuel tank, 35-inch mud-terrain tires, 2-inch factory lift, Multimatic DSSV dampers with new Jounce Control Dampers, front and rear electronic locking differentials, underbody cameras, and Super Cruise.

A new Baja drive mode adjusts throttle response, transmission behavior, damper tuning, stability control, and traction control for higher-speed operation over sand, loose surfaces, and rough terrain.

The 6.6L V-8 is available. An AT4X AEV Edition will also return with AEV bumpers, skid plates, recovery hooks, 18-inch beadlock-capable wheels, and other off-road equipment.

Sierra Denali

Denali combines Sierra capability with GMC’s premium interior and technology features. The 5.7L V-8 is standard, while the 6.6L V-8 and Duramax diesel are available.

Standard equipment includes Super Cruise with trailering capability, Denali Premium Suspension, 12-way heated and ventilated front seats, panoramic sunroof, Head-Up Display, Rear Camera Mirror, MultiPro center console, and the 16.3-inch center and 12.2-inch driver displays.

Sierra Denali Ultimate

Denali Ultimate sits at the top of the Sierra 1500 range. The 6.6L V-8 and 34-gallon fuel tank are standard. The Duramax diesel is available.

Other standard features include 14-way heated, ventilated, and massaging front seats, an 11.5-inch passenger display, panoramic sunroof, Super Cruise, 16.3-inch articulating infotainment display, 12.2-inch Driver Information Center, 15-inch Head-Up Display, Rear Camera Mirror, underbody cameras, MultiPro center console, and 22-inch wheels.

2027 Sierra Pro Fleet Highlights

For commercial fleets, Pro is the most directly work-focused Sierra 1500 configuration.

For fleets comparing the Pro against more retail-oriented trims, the biggest distinction is how much work-related equipment comes standard. The trailer hitch, brake controller, high-capacity air cleaner, full-size displays, and expanded safety package are included without requiring a move farther up the trim ladder.

Payload Towing and Weight

Maximum available payload for the 2027 Sierra 1500 reaches 2,310 pounds in a 2WD Regular Cab equipped with the TurboMax.

Maximum available trailering reaches 13,500 pounds with the 5.7L V-8 in a properly equipped 4WD Double Cab with the Max Trailering Package.

Capability varies substantially by cab, drivetrain, engine, bed, equipment, and package combination.

Maximum Payload by Engine

These figures represent maximum ratings within each engine and cab grouping. Actual payload is configuration-specific and should be verified against the vehicle’s certification label when ordering or operating a truck.

Maximum Trailering by Engine

NHT refers to configurations equipped with the Max Trailering Package.

Max Trailering Package

The 2027 Sierra 1500’s highest towing ratings depend on the available Max Trailering Package. With the package, a 4WD Double Cab equipped with the 5.7L V-8 can tow up to 13,500 pounds when properly equipped. A 4WD Crew Cab with the same engine can tow up to 13,300 pounds, while a 4WD Crew Cab with the 3.0L Duramax can tow up to 12,100 pounds.

Because towing capability changes significantly based on cab, drivetrain, engine, and package selection, fleets should verify the complete configuration rather than relying only on the engine’s maximum published rating.

GVWR and Curb Weight

Maximum GVWR varies by cab, drivetrain, bed, and equipment. Regular Cab models range as high as 7,100 pounds GVWR, while Double Cab configurations reach as high as 7,450 pounds with the Max Trailering Package.

Crew Cab GVWR reaches 7,500 pounds on AT4X configurations. Other Crew Cab configurations range from 7,100 to 7,450 pounds depending on drivetrain, suspension, bed, and trailering equipment.

Base curb weight also varies considerably across the lineup. TurboMax models start as low as approximately 4,590 pounds, while heavily equipped Duramax, V-8, lifted, and AT4X models exceed 6,000 pounds.

Fleets should match the complete configuration, rather than engine choice alone, against required payload, GVWR, towing, and operating requirements.

Chassis Suspension and Brakes

The Sierra 1500 uses an independent coil-over-shock front suspension and solid-axle Hotchkiss rear suspension. Standard models use twin-tube dampers with frequency-dependent damping. AT4 uses monotube shocks, while AT4X moves to Multimatic DSSV dampers. Denali and Denali Ultimate use Adaptive Ride Control.

At the rear, Sierra uses either two-stage 1+1 steel leaf springs or progressive-rate composite mono-leaf springs depending on configuration. Electric power-assisted rack-and-pinion steering is standard.

Front brakes use four 51mm fixed cast-iron calipers with 13.5-inch vented rotors. Rear brakes use 51mm sliding cast-iron calipers with an integrated electric parking brake and 13.6-inch vented rotors.

Available wheel sizes range from 17-inch steel and aluminum wheels through 22-inch aluminum wheels depending on trim and configuration.

Fuel Tank Capacity

Sierra fuel tank capacity varies by cab and configuration. Regular Cab models offer an approximately 28-gallon tank. Double Cab and Crew Cab models can be equipped with an approximately 34-gallon tank.

The approximately 34-gallon tank is available with the 5.7L V-8, 6.6L V-8, and Duramax diesel.

For diesel applications, GMC estimates more than 900 miles of available highway range when the 3.0L Duramax is paired with the 34-gallon tank.

Fleet and Work-Related Features

For fleet users, the Sierra Pro combines the truck’s lowest starting price with several pieces of equipment that would otherwise have traditionally required additional optioning.

The Pro includes a trailer hitch and integrated trailer brake controller, high-capacity air cleaner, 10-speed automatic transmission, Adaptive Cruise Control, parking assistance, automatic emergency braking technologies, and both the 16.3-inch infotainment display and 12.2-inch Driver Information Center.

The optional 5.7L V-8 and Duramax diesel give fleets alternatives to the standard TurboMax for applications where towing, highway use, diesel commonality, or operating range may take priority.

Multiple cab and box configurations will also be offered as production expands.

MultiPro Tailgate

The available MultiPro Tailgate receives several changes for 2027.

GMC has added four tie-downs to the tailgate itself along with an integrated ruler system. Combined with the cargo bed, the truck offers 16 standard bed tie-down locations.

MultiPro Center Console

The new MultiPro center console combines storage with a work surface that can be extended for use inside the cab.

For drivers who use their trucks as mobile offices, the added surface provides space for paperwork, a tablet, or other work-related tasks without requiring an aftermarket writing surface.

Towing Technology

The 2027 Sierra combines its mechanical towing equipment with an expanded collection of camera, trailering, and driver-assistance technologies.

• Available trailering tools include Hitch View, transparent trailer views, mobile trailer-light checks, the in-vehicle Trailering App, and dedicated driver displays.
• An available camera system provides as many as 19 views. New views include Cabin Glance and front and rear underbody cameras, with a wash system available for the underbody cameras.
• The Sierra also introduces an available Trailer Brake Gain Assistant.
• Super Cruise with trailering capability is standard on AT4, AT4X, Denali, and Denali Ultimate and available on Elevation.
• On equipped trucks, Super Cruise supports Automatic Lane Change and Turn Signal Initiated Lane Change.

2027 GMC Sierra 1500 Technology Fit for Fleets

Every 2027 Sierra 1500 receives a 16.3-inch center infotainment touchscreen and 12.2-inch Driver Information Center.

The truck also introduces GM’s new user interface, which places greater emphasis on truck-related functions such as trailering, vehicle status, navigation, cameras, and off-road information.

A split-screen home view allows drivers to keep navigation visible alongside vehicle information, media, trailering data, or other functions. Apple CarPlay and Android Auto are integrated with native vehicle functions. Google built-in features include Google Maps, Google Gemini, apps through Google Play, and over-the-air software updates.

An available articulating version of the 16.3-inch center display can move to reveal concealed storage behind the screen. An available 11.5-inch front passenger display provides a separate interface for passenger entertainment and information. Polarized display technology helps prevent that content from being visible to the driver.

Depending on equipment, Sierra can also provide six USB ports, a 120-volt center-console outlet, HDMI connectivity, 5G connectivity, and dual wireless phone charging.

Safety and Driver Assistance Technology

GMC expands the Sierra 1500’s standard safety package for 2027, including several features that now extend throughout the lineup.

Standard equipment includes:

• Intersection Automatic Emergency Braking.
• Front Pedestrian and Bicyclist Braking.
• Side Bicyclist Alert.
• Reverse Automatic Braking.
• Safety Alert Seat.
• Adaptive Cruise Control.
• IntelliBeam.
• Front and Rear Park Assist.
• Forward Collision Alert.
• Rear Cross Traffic Braking.
• Blind Zone Steering Assist.
• Rear Pedestrian Alert.
• HD Rear Vision Camera.

That means even the work-focused Pro starts with Adaptive Cruise Control, parking assistance, multiple automatic braking systems, and pedestrian and bicyclist detection technologies.

2027 GMC Sierra 1500 Pricing

GMC has announced starting prices for all six Sierra 1500 trims.

The prices below apply to 4WD Crew Cab configurations and include the $2,795 destination freight charge.

Pricing for Regular Cab, Double Cab, other drivetrains, bed configurations, option packages, and additional equipment will vary.

For fleet buyers, the $51,295 Pro price provides a useful starting reference, but actual acquisition pricing will depend on drivetrain, cab and bed configuration, engine, fleet programs, options, and volume.

2027 GMC Sierra 1500 Ordering and Availability

The first 2027 GMC Sierra 1500 models are expected to reach dealerships before the end of the 2026 calendar year. GMC says additional Regular Cab, Double Cab, and other configurations will become available as production expands.

Fleets should verify order-bank timing, fleet availability, individual configuration pricing, and production constraints for the exact truck being ordered.
