GMC Sierra HD AT4X: The ultimate off-road truck for 2024

If you’re looking for a heavy-duty pickup truck that can handle any terrain, you might want to check out the GMC Sierra HD AT4X. This is the most rugged and capable version of the Sierra HD, and it’s coming to dealerships in 2024.

The GMC Sierra HD AT4X is based on the Sierra HD AT4, which is already a formidable off-roader with features like a two-inch suspension lift, Rancho shocks, skid plates, locking rear differential, hill descent control, and off-road mode. But the AT4X takes it to the next level with exclusive enhancements that make it stand out.

First, the GMC Sierra HD AT4X has a wider track and larger fender flares that accommodate massive 37-inch Goodyear Wrangler MT tires. These tires provide exceptional grip and traction on any surface, from mud and sand to rocks and snow. They also give the truck a more aggressive and muscular appearance.

Secondly, the GMC Sierra HD AT4X has a new front bumper with an integrated winch that can pull up to 12,000 pounds. This is a handy feature for getting out of sticky situations or helping other vehicles in need. The bumper also has tow hooks and LED fog lights for added functionality.

Thirdly, the GMC Sierra HD AT4X has a unique grille with a large GMC logo and red accents. The grille also features a camera system that provides a 360-degree view of the surroundings, which is useful for navigating tight spots or avoiding obstacles. The hood has a functional scoop that feeds air to the engine for better performance and cooling.

Speaking of the engine, the GMC Sierra HD AT4X comes with two options: a 6.6-liter V8 gas engine that delivers 401 horsepower and 464 pound-feet of torque or a 6.6-liter Duramax turbodiesel engine that cranks out 445 horsepower and 910 pound-feet of torque. Both engines are paired with a 10-speed automatic transmission that shifts smoothly and efficiently.

The GMC Sierra HD AT4X also has a sophisticated four-wheel-drive system that can be adjusted to different modes depending on the terrain and driving conditions. The system includes:

• An electronic locking front differential.
• An Eaton locking rear differential.
• An Autotrac transfer case that allows for automatic or manual selection of four-wheel-drive modes.

The GMC Sierra HD AT4X is tough on the outside but comfortable and luxurious on the inside. The cabin is spacious and well-appointed, with leather seats, carbon fiber trim, and red stitching. The seats are heated and ventilated, and the driver’s seat has 10-way power adjustment and memory settings.

The GMC Sierra HD AT4X also has a host of advanced technology features that make driving easier and safer. The truck has a 15-inch head-up display that projects key information on the windshield, such as speed, navigation, and off-road data. It also has a 12-inch digital instrument cluster that can be customized to show different gauges and indicators.

The GMC Sierra HD AT4X also has a 13.4-inch touchscreen infotainment system that supports wireless Apple CarPlay and Android Auto, as well as SiriusXM satellite radio and Amazon Alexa integration. The system also has a Bose premium sound system that delivers crisp and clear audio quality.

The GMC Sierra HD AT4X also has a suite of driver assistance features that help prevent accidents and collisions. The truck has a forward collision alert, automatic emergency braking, lane departure warning, lane keep assist, blind spot monitor, rear cross-traffic alert, adaptive cruise control, rear camera mirror, and trailer sway control.

The GMC Sierra HD AT4X is expected to go on sale in late 2023 as a 2024 model-year vehicle. The pricing has not been announced yet, but it will likely be higher than the base price of the Sierra HD AT4, which starts at $59,295 for the gas engine and $63,895 for the diesel engine.

The GMC Sierra HD AT4X is a truck that can do it all: haul heavy loads, tow large trailers, and conquer any terrain. It is the ultimate off-road truck for those who want to explore new places and have fun along the way.
