2024 GMC Sierra HD AEV Grande Concept Is a Formidable Flatbed Truck

• 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.
