Key Features of the 2026 GMC Sierra 1500

TurboMax™ engine

Standard power starts strong with the TurboMax™ engine—engineered to deliver 310 horsepower and best-in-class standard torque of 430 lb.-ft. That deep torque arrives early for responsive takeoffs and confident towing, while the available max towing of up to 9,400 lbs. with this engine underscores real-world capability. GMC bolsters this performance with a 5-year/100,000-mile Powertrain Limited Warranty for added peace of mind. On the road, the powertrain’s calibration works smoothly with the available 8-speed or 10-speed automatic transmissions found across the lineup to balance spirited performance with composed drivability. For shoppers who want a truck that can transform a routine merge or a steep on-ramp into an effortless maneuver, the TurboMax™ engine’s robust torque curve makes the Sierra 1500 feel reassuringly strong and refined.

Duramax® 3.0L Turbo-Diesel engine

For sustained towing and long-distance driving, the available Duramax® 3.0L Turbo-Diesel with a 10-speed automatic transmission is a standout. Properly equipped, the Sierra 1500 with the Duramax diesel offers an available max diesel towing capacity of up to 13,300 lbs.—a confidence-inspiring number when you’re pulling campers, boats, or equipment. Diesel torque helps stabilize trailer dynamics at highway speeds, while integrated towing technology—like the available ProGrade® Trailering System and available Trailer Brake Controller—adds precision. If you often navigate mountain passes or windy plains with a trailer in tow, pairing the Duramax® diesel with the available Max Trailering Package enhances cooling, suspension tuning, and rear-axle hardware so your Sierra 1500 remains composed under load.

ProGrade® Trailering System

Towing should feel intuitive, and the available ProGrade® Trailering System helps make it that way. Integrated tools within the truck’s infotainment interface guide you through pre-departure checklists, trailer profile creation, and connection status. The in-vehicle Trailering App offers custom trailer profiles and trailer statuses that simplify repeat trips, whether you’re swapping between utility and travel trailers. Layer in the available Trailer Brake Controller—integrated with the antilock brake system—and you’ll appreciate the measured brake force signaling to compatible electric-controlled trailer brakes. The result is towing that’s smoother, safer-feeling, and easier to manage solo or with a co-pilot.

MultiPro™ Tailgate

The world’s first available six-function GMC MultiPro™ Tailgate helps you handle awkward loads, frequent climbs into the bed, and tight-quarters work with ease. Configurations include a primary gate, load stop, inner gate with work surface, and a step setup that pairs with an assist handle for more secure footing. When you’re packing gear for a weekend or organizing work tools, the MultiPro™ Tailgate’s flexibility can cut down on time and strain. Add the available MultiPro Tailgate Audio System by KICKER for campsite soundtracks and community events. Whether you own your business or simply juggle a busy household, this tailgate becomes a daily quality-of-life upgrade.

13.4" diagonal Premium GMC Infotainment System with Google built-in

Inside, the Sierra 1500’s available 13.4" diagonal Premium GMC Infotainment System with Google built-in turns the cabin into a command center. With Google Assistant, Google Maps, and Google Play compatibility integrated, you can set destinations by voice, manage your calendar, or find trailheads without reaching for your phone. The high-resolution display pairs naturally with the 12.3" diagonal Driver Information Center for at-a-glance vehicle data and, when equipped, the available 15" diagonal multicolor Head-Up Display that projects key info onto the windshield. Add wireless phone projection, and the interior becomes both a productivity hub and a place to unwind with your playlists—ideal for long days behind the wheel or quick runs between job sites.
