People use pickup trucks as everyday vehicles, even heavy-duty models, so it’s not surprising to see automakers adding more luxury and capability to their most work-ready models. Rugged, off-road-read heavy-duty trucks are nothing new, but GMC’s taking it to the next level with the new Sierra HD AT4X and Extreme AEV Edition trucks. The pair comes with a slew of upgrades to improve their off-road capability while maintaining the workhorse attitude that people expect from heavy-duty trucks.

The 2024 GMC Sierra HD AT4X gets a 6.6-liter gas V8 as standard, but buyers can add the 6.6-liter Duramax diesel. A ten-speed automatic transmission and four-wheel drive are standard. The truck delivers 18,500 pounds of towing, a 1.5-inch lift kit, Multimatic DSSV dampers, an electronic locking rear differential, and 35-inch Goodyear tires. The HD also gets a new off-road driving mode, which recalibrates braking, steering, and other settings to improve traction and performance.

The Extreme AEV Edition brings touches from American Expedition Vehicles, including 18-inch wheels and underbody steel skid plates. It also offers steep bumpers with integrated recovery points and a winch mounting point.

Both trucks bring the luxury inside, where GMC equipped leather upholstery and massaging front seats. Ash wood trim and a Bose 12-speaker premium stereo come standard, along with a 13.4-inch touchscreen and 12.3-inch digital gauge cluster. GMC offers several driver aids, but most are withheld in added-cost options package. Available tech includes a transparent trailer-view camera system, blind spot monitoring with trailer coverage, and adaptive cruise control with trailering.

GMC hasn’t detailed pricing for the new trucks yet but said more information would become available closer to their on-sale date this fall.

Sad fact is thats all that truck can safely tow. You need to spring for a 2500 or 3500 to actually tow a large travel trailer.

Lou_BC I like the fact that Kia is going after dealerships like this. I ran across some outright lies and misleading advertisements when looking for my current truck. I filed a complaint with GM Canada. Their reply, "times are tough and dealers are independent companies separate from GMC.
Canam23 While the Mirage makes me ill just looking at it, I believe that Mitsubishi is well above Nissan in reliability. Everyone I knew who's sister bought a Versa had constant issues with them.
Bd2 See guys it's like this : they say a that if you pay a man enough he will walk barefoot to hell and this Kia dealership could be analogized as hell with the Telluride being the holy grail of under $100K SUVs. Kia vehicles are so good, buyers are willing to tolerate the worst, sleaziest, nastiest, unethical and incompetent dealership experience just to park themselves in the best of the best instead of settling for a Lexus or Toyota or even an Acura. It's just a testament to the hard working young personnel at Hyundai Kia Genesis factories across Ala-BAM-A! who really give it their all including their lives to build the best that keeps the customer coming back no matter how terrible the front line dealership is. Let that sink in.
Lou_BC I haven't burned a drop of gasoline in the past 2 years ;)
THX1136 One thing the government does well is not look to the future when considering lawmaking/regulation of industries along with legislating via exceptions. Appreciate the article and the discussions. Don't think this is a 'one size fits all' situation. That, along with legislators who don't have the will to legislate what's best for all instead of the few. Probably wrong on that, but I've been wrong before. Got to keep my averages up, ya know.
