Technical Sheet of the 2025 Chevrolet Colorado ZR2 Bison Proves Why It’s the Most Brutal Pickup

Get ready for the pickup truck that looks like it came straight out of a post-apocalyptic movie, built to face the end of the world and come out unscathed. The 2025 Chevrolet Colorado ZR2 Bison isn’t just a pickup; it’s a declaration of war against impassable terrain. And let me tell you, it’s here to win!

Developed in partnership with American Expedition Vehicles (AEV), this special version of the already tough Colorado ZR2 takes the off-road concept to a level that, frankly, very few dare to reach. It’s the ultimate machine for those who have gasoline (and mud) in their veins and aren’t satisfied with paved roads.

Imposing Design: What Sets It Apart?

At first glance, the 2025 ZR2 Bison screams toughness. The stamped steel AEV bumpers aren’t just for show, damn it. They’re built to take heavy hits and, as a bonus, improve approach and departure angles—essential for not getting stuck on any obstacle.

Up front, the integrated winches show they mean business. Fog lights, rear design optimized for ground clearance… Every detail was calculated. But what really grabs your attention are the 17-inch AEV wheels wrapped in 35-inch mud/terrain tires. Holy shit, these are the biggest in the segment! That guarantees traction that makes you question if there’s any limit to this pickup.

And to protect what matters? Five boron steel skid plates for the oil pan and differentials. It’s like putting medieval armor on your vehicle. Oil pan, transmission, transfer case, fuel tank, and rear differential—all guarded. If you thought the trail was tough, think again, because this Bison is laughing in your face.

Wild Heart: What Engine and Transmission?

Under the hood, the ZR2 Bison boasts an engine that means serious business. It’s a 2.7L Turbo Inline 4-cylinder that delivers 310 horsepower and 430 lb-ft (58.2 kg·m) of torque. It might seem like “just” a four-cylinder to some V8-loving folks, but this High-Output engine has plenty of breath and beastly low-end torque, perfect for crawling on trails.

The transmission is an eight-speed automatic, tuned to be efficient both on road and in the mud. And the drivetrain? It’s 4×4 with low-range and electronically locking front and rear differentials. That means you have full control over the power, deciding exactly where it goes. For those who take off-roading seriously, this, my friend, is gold.

Key Engine Specs

• Engine: 2.7L Turbo High-Output, Inline 4-cylinder
• Fuel: Gasoline
• Max Power: 310 hp @ 5,600 rpm
• Max Torque: 430 lb-ft (59.4 kg·m) @ 3,000 rpm
• Transmission: 8-speed Automatic
• Drivetrain: 4×4 with low-range and locking differentials

Ready for War: How’s Its Off-Road Performance?

This is where the ZR2 Bison truly shows what it’s made of. The suspension is its major difference. Equipped with Multimatic DSSV (Dynamic Suspensions Spool Valve) dampers, this pickup soaks up impacts like it’s floating. The DSSV technology instantly adapts to the terrain, offering damping control that, holy crap, is unreal.

The suspension travel is also increased compared to the standard ZR2, meaning more articulation to overcome obstacles and less chance of having a wheel in the air. Add to that the improved approach and departure angles and a generous 12.3-inch (31.2 cm) ground clearance, and you’ve got a machine that honestly scares with how capable it is. Compared to other pickups, like the 2026 Ram 1500 (which plays in a different league in size and engine), the Colorado Bison really shines in the extreme midsize pickup segment.

While some electric SUVs are starting to dabble in off-roading, like the 2025 Opel Frontera Gravel, the Bison’s approach is brutally mechanical and focused on durability and capability in harsh conditions. It’s for those who want to throw themselves at it without caring about the vehicle.

Inside the Beast: Technology and Comfort?

Don’t think that being a trail machine means it’s rustic inside. The Colorado ZR2 Bison balances ruggedness with technology and comfort, damn it. The seats have durable, easy-to-clean upholstery with the AEV logo embroidered, so you never forget you’re in a special edition.

The dashboard is fully digital with an 11-inch configurable screen, and the multimedia center has a generous 11.3-inch touchscreen, compatible with wireless Android Auto and Apple CarPlay. It even has 360-degree cameras, including an underbody camera, so you can see exactly what you’re driving over. Admit it, that’s fucking awesome on a tough trail!

Robust Safety: Does It Really Protect?

Yes, it protects. The body structure is reinforced, and the pickup comes with a complete package of driver aids. Automatic emergency braking, forward collision alert, lane keep assist, blind spot warning, adaptive cruise control… It’s a shitload of tech to help you not screw up, both on and off-road.

The price in the United States starts around US$60,000. Converted to Brazilian Real and adding import taxes, fees, etc., it would be a price that, damn, would be prohibitive for most. But the hope is that GM brings at least part of this “Bison soul” to the new S10, especially the off-road-oriented versions.
