The new trailering app offers a variety of unique features to help improve your trailering experience. The app is integrated with and accessible through Sierra Denali’s available GMC Infotainment System,4 with features including:
The available 6.6L Duramax® Turbo Diesel V8, which produces 445 horsepower and 910 lb.-ft. of torque, is paired with the all-new Allison® 10-speed automatic transmission – the first of its kind in the heavy-duty pickup segment. The all-new 10-speed transmission with closer gear spacing allows the engine to operate in an optimal range at all times with varying load and terrain conditions. This, combined with fortified components used throughout Sierra Heavy Duty’s driveline, provides maximum torque to the wheels at all times.
An available system of intelligent technologies improves the trailering experience by adding functionality and convenience. An In-Vehicle Trailering App†, smart trailer integration and up to 15 unique class-leading, high-definition camera views are available to help improve the hitching and towing experience.
Innovative technology in partnership with ASA Electronics’ iN-Command® Control System allows you to easily control and monitor your trailer from inside the truck’s cabin. Before you arrive at your destination, you can adjust the trailer’s interior temperature, turn on the water heater and generator and check water and gas tank levels.
This available feature helps you see directly behind the trailer for improved visibility.
Let’s you see inside the truck bed to help with fifth-wheel hitching, and to check on cargo while driving.
This view shows the side of your truck, and if trailering, the front of the trailer. While towing with a conventional hitch trailer, rear facing side view cameras with available articulation functionality will automatically adjust the camera view in the direction the trailer is moving to provide maximum visibility.
The world’s first six-function MultiProTM Tailgate, available on Sierra Heavy Duty, improves cargo-box accessibility and functionality by adapting to your needs with six different functions – making loading and unloading quicker and easier.
The first Heavy Duty pickup in its class† to offer a multicolour 15″ diagonal Head-Up Display helps keep your eyes on the road by conveniently projecting key information directly onto the windshield such as speed, active safety information, available Navigation† and inclinometer that measures grade.
Building on the bold foundations of the Sierra Heavy Duty pickup truck, AT4 delivers rugged design and off-road capability, giving you the power to go beyond the pavement.
