AEV took a 2024 GMC Sierra 2500HD and outfitted 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.
