It comes as no surprise that car manufacturers have been doubling down on the off-road capabilities of their truck and SUV lineups in recent years. Not only did the pandemic get people exploring and overlanding quite a bit more but improvements in max payload and infotainment will only get you so excited when your main priority is venturing off-grid. Today, GMC has added an AT4X Edition and AT4X AEV Edition to its Sierra 2500 HD pickup.
While the AT4 trim had been given to the Sierra HD in past years, the AT4X brings more power to the V8 for more capability when trailering, now boasting up to 470hp and 975lb.ft of torque when equipped with the 6.6L Duramax Turbo-Diesel engine. There’s also a standard gas engine option that gives you 401hp and 464lb.ft of torque. Likewise, the max trailering gets bumped up to 18,500lbs with the diesel variant (16,000lbs with gas). Offering the most trailering technology in its class, the AT4X also comes with a 1.5-inch suspension lift, 35-inch Goodyear Territory tires, larger control arms in the front, steering knuckles, a larger steel transfer case skid plate, and front aluminum skid plate. For optimized performance, the Off-Road Mode adjusts the brakes, traction, and stability when driving.
As for the AT4X AEV Edition, the Sierra 2500 HD will get the addition of stamped steel bumpers with integrated recovery points and a front winch to aid the driver. Aside from the unique badging on the outside and specific interior design cues, the trim also comes with special 18-inch Salta wheels.
So far, the AT4X existed only in GMC’s mid-size Canyon truck and the standard Sierra 1500 pickup. Now, the heavy-duty version of the Sierra gets the off-road package to become the most off-road capable truck in the American marque’s range. No pricing or release date has been announced, but you can learn more about the Sierra 2500 HD AT4X trims on GMC’s website.
