The 2024 GMC Acadia SUV has officially grown up, and I mean that literally. If you remember the previous generation, it was a bit of a "tweener"—larger than a compact crossover but definitely smaller than most of its three-row rivals. Well, GMC heard the feedback, went back to the drawing board, and decided that bigger is indeed better. For this new model year, the Acadia has returned to its roots as a true full-sized mid-size SUV, and it's a lot more impressive for it.
It's not just about the footprint, though. Everything from the engine under the hood to the tech inside the cabin has been completely overhauled. If you've been looking for something that bridges the gap between a standard family hauler and a luxury cruiser, this might be the sweet spot.
A Massive Leap in Size and Presence
The first thing you'll notice when you see the 2024 GMC Acadia SUV in person is that it looks like a baby Yukon. It's got that squared-off, muscular stance that GMC is known for these days. It's about 10.6 inches longer and 3.2 inches taller than the 2023 model. That might not sound like a huge difference on paper, but in the driveway or a parking lot, the presence is night and day.
The longer wheelbase means more room for everyone. One of the biggest complaints about the older version was that the third row was really only for kids—and even then, it was a squeeze. Now? You can actually fit adults back there without them wanting to stage a mutiny after twenty minutes. Plus, the cargo space behind that third row has jumped by nearly 80 percent. You can finally fit a grocery haul and the kids at the same time.
What's Under the Hood?
GMC made a pretty bold move with the powertrain this time around. They've retired the old V6 and the base four-cylinder in favor of a single, powerful engine across the entire lineup. Every 2024 GMC Acadia SUV now comes with a 2.5-liter turbocharged four-cylinder engine.
Now, I know some people get nervous when they hear "four-cylinder" in a big SUV, but don't let the cylinder count fool you. This thing puts out 328 horsepower and 326 lb-ft of torque. That's actually more power than the old V6 had. It's paired with an eight-speed automatic transmission that's smooth and doesn't hunt for gears. Whether you're merging onto the highway or towing a small boat (it's rated for up to 5,000 pounds), it feels plenty capable.
Stepping Inside the Cabin
If the exterior is about size, the interior is all about the "wow" factor. The centerpiece of the dashboard is a massive 15-inch portrait-oriented infotainment screen. It's standard on every trim level, which is a nice touch because usually, you have to pay extra for the "good" screen.
The system is Google-built, so it has Google Maps and Google Assistant baked right in. It's very intuitive—if you can use a smartphone, you can use this. What I really appreciate is that GMC kept physical toggles and buttons for the climate control at the bottom of the screen. There's nothing more annoying than having to dive through three menus just to turn down the AC when it's 90 degrees out.
The materials feel a step up from the previous generation, too. Even in the base Elevation trim, it feels solid and well-put-together. But if you really want to lean into the premium side of things, the higher trims take it to another level.
The Rugged AT4 Trim
If you're the type who likes to head out to the campsite or hit some light trails, the AT4 trim is probably where you'll want to look. It's not just a styling package; it actually gets a one-inch lift, a wider track, and a specific off-road tuned suspension. It also sports some beefy all-terrain tires and red tow hooks that give it a much meaner look. It uses a twin-clutch all-wheel-drive system that helps move power around when things get slippery, which is great for peace of mind during winter storms or on gravel roads.
The Luxurious Denali
On the flip side, we have the Denali. This is GMC's flagship trim, and it's basically a luxury vehicle without the "fancy" badge. You get 22-inch machined aluminum wheels, a unique grille, and an interior filled with laser-etched wood trim and perforated leather seats. The Denali also comes with active noise cancellation, making the cabin incredibly quiet. It's the kind of vehicle that makes a long road trip feel like a breeze rather than a chore.
Super Cruise: The Party Trick
One of the coolest features available on the 2024 GMC Acadia SUV is Super Cruise. If you haven't tried it, it's GM's hands-free driver assistance technology. It works on hundreds of thousands of miles of compatible highways across North America.
It's honestly a bit surreal the first time you take your hands off the wheel at 70 mph, but the system is incredibly sophisticated. It handles steering, braking, and even lane changes automatically. For someone who spends a lot of time on the interstate, this feature is a total game-changer for reducing driver fatigue. It's available on almost all trims now, not just the top-tier Denali, which is a huge win for buyers.
Safety and Practicality
Beyond the flashy tech, the 2024 GMC Acadia SUV is loaded with safety gear. You get things like forward collision alert, following distance indicators, and enhanced lane-keep assist as standard. But they've also added some newer tech, like a 360-degree camera system with up to nine different views. This is a lifesaver when you're trying to park a vehicle this size in a tight garage or a busy grocery store lot.
The seating configuration is also very flexible. You can go with captain's chairs in the second row for a bit more "executive" feel and easier access to the back, or a bench seat if you absolutely need to carry eight people. The seats fold flat easily, giving you a massive load floor if you're doing a big IKEA run.
Final Thoughts
It's clear that GMC didn't just want to update the Acadia; they wanted to redefine what it stands for. By making it bigger, they've moved it back into a space where it can truly compete with the heavy hitters in the three-row SUV segment.
Is it the right choice for everyone? Well, if you have a tiny garage or you're terrified of parking something substantial, you might find it a bit intimidating at first. But for families who felt cramped in the old model or for drivers who want a "truck-like" feel without the thirst of a V8 engine, the 2024 GMC Acadia SUV hits all the right notes. It's comfortable, it's packed with some of the best tech in the industry, and it finally has the room to match its bold styling.
Whether you're leaning toward the off-road ready AT4 or the posh Denali, you're getting a vehicle that feels much more "professional grade" than it ever has before. It's a solid reminder that sometimes, listening to the customers and going back to a bigger footprint is exactly what a model needs to find its stride again.
