Meet the 2024 Sierra 2500HD AT4X, AEV Edition: Overland News

GMC Takes Heavy Duty Further Off-Road

GMC has been making tangible strides into the off-road world with their Sierra 1500 AT4X and Canyon AT4X recently. Now, GMC is taking another step, introducing the first-ever 2024 GMC Sierra HD AT4X. It’s their goal that this truck enables adventurers to go further, while still having the towing capability essential for heavy duty haulers. The Sierra HD AT4X balances increased off-road capability with smooth on-road handling. Plus, it offers the most trailering technology in its class, as well as first-class luxury and comfort features. We’re drooling already and can’t wait for the chance to get behind the wheel.

“GMC’s AT4X trim, which will be available across the entire GMC truck lineup, offers customers more premium choices when it comes to ‘do-it-all’ capabilities,” said Duncan Aldred, Global Vice President of Buick-GMC. “Each model delivers unique strengths, with the all-new Sierra HD AT4X taking it to the max, giving our customers the most luxurious and most off-road capable HD we’ve ever offered. AT4X means you can conquer almost any terrain, in complete comfort and with the towing power to bring your recreational toys, gear or camper along for the adventure.”

AT4X

Building on the foundation of the revamped 2024 Sierra HD, which receives fresh design updates, new available premium interiors and an all-new tech-focused layout, the new Sierra HD AT4X’s highlights include:

• Available 18,500-pound max trailering capacity
• Factory-installed 1.5-inch (38mm) suspension lift
• Multimatic DSSV dampers
• Rear e-locking differential
• 35-inch Goodyear Territory tires
• Specific front upper and lower control arms and specific steering knuckles
• Larger steel transfer case skid plate and front aluminum skid plate
• Unique Obsidian Rush interior featuring premium appointments like massaging, full grain leather-wrapped front seats

Extreme Off Roading

The available AT4X AEV Edition takes this truck to the next level. Robust stamped steel bumpers with integrated recovery points and front winch capability provide extra driver confidence and protection. Additionally, heavy duty steel skid plates help keep vital components protected on the trail. Unique 18-inch Salta wheels and 35-inch tires provide plenty of traction. And (The rumors are true!) beyond the standard 6.6L gas engine, the new AT4X offers the turbocharged pulling power of the available 6.6L Duramax Turbo-Diesel. Enhanced for 2024, it will deliver 470 hp and 975 lb-ft of torque, offering more power all around.

2024 Sierra AT4X Coming in Q3 2023

The 2024 GMC Sierra HD AT4X and AT4X AEV Edition are expected to arrive on a lot near you in the fall of 2023. Expect to see pricing announced as we get closer to the start of production!
