- AEV took a 2024 GMC Sierra 2500HD and outfitted it to look like a formidable flatbed pickup truck.
- The regular-cab model adds steel bumpers, a huge brush guard, off-road lights, and a winch.
- The heavy-duty Sierra is powered by a Duramax diesel 6.6-liter V-8 that breathes through a snorkel air intake.
American Expedition Vehicles (AEV) knows how to make a tough truck even tougher. Take the 2024 GMC Sierra 2500HD hat the company transformed for this year’s SEMA show. What started out as a regular-cab, long-bed model is outfitted with all manner of AEV add-ons that turn it into a heavy-duty overlander.
A Sierra HD for SEMA
The Sierra HD Grande concept looks like it could drive through a brick wall. That’s mostly because of its huge grille guard, which is an AEV prototype that provides protection for the headlights too. It features four powerful off-road lights, and below them is a 12,500-pound ComeUp winch.
That winch is integrated into a steel front bumper that’s the same one found on the Sierra HD AT4X AEV Edition. Just like that truck, the concept has the AT4X suspension that includes Multimatic spool-valve dampers and a 1.5-inch lift. Those buoy giant 40-inch BFGoodrich all-terrain tires mounted on Salta XD wheels. Should one of those go flat, there’s a full-size spare in the truck’s eight-foot aluminum flatbed.
To better ensure its underbody doesn’t get too banged up on treacherous terrain, AEV bolted on stamped steel skid plates. There’s also a custom steel bumper out back with a 9500-pound winch. Other accessories include an ARB air compressor and a snorkel air intake, which lets the Duramax diesel—a 6.6-liter V-8 making 470 horsepower and 975 pound-feet of torque—breath should the truck need to wade into water.
The Sierra HD Grande concept looks formidable. That’s what oversized tires and a big brush guard will do. Its custom paint isn’t something you’ll find on a factory model, and either are the prototype AEV front fender flares. While a 2024 GMC Sierra 2500HD regular cab starts at just over $47K, this concept’s mix of custom elements make it priceless.

Eric Stafford’s automobile addiction began before he could walk, and it has fueled his passion to write news, reviews, and more for Car and Driver since 2016. His aspiration growing up was to become a millionaire with a Jay Leno–like car collection. Apparently, getting rich is harder than social-media influencers make it seem, so he avoided financial success entirely to become an automotive journalist and drive new cars for a living. After earning a journalism degree at Central Michigan University and working at a daily newspaper, the years of basically burning money on failed project cars and lemon-flavored jalopies finally paid off when Car and Driver hired him. His garage currently includes a 2010 Acura RDX, a manual ’97 Chevy Camaro Z/28, and a ’90 Honda CRX Si.
