Should You Buy the 2025 Chevrolet Suburban?

Some vehicles feel like they were born to play a certain role. The Chevrolet Suburban, in its near-century-long legacy, has always been that truck, the one big rig for big lives. For 2025, GM has gently refined the formula, kept what matters, while adding some meaningful tech, interior updates, and a more powerful diesel powertrain. But is that enough to keep it top-of-mind in a world where $100K-plus SUVs are now the norm?

After driving the 2025 Suburban RST with the 6.2L V8, adaptive air suspension, and 24-inch wheels, here’s what you need to know before backing it into your (very long) driveway.

Key Facts About the 2025 Chevrolet Suburban

The 2025 Chevrolet Suburban rides on the same chassis and layout as before but introduces key changes that increase its appeal to those who live large. The Suburban’s length stretches to nearly 5.75 metres, offering cavernous interior space, now complemented by a revamped dashboard with a massive 17.7-inch touchscreen angled toward the driver.

Buyers can stick with one of two V8s or opt for a new second-generation 3.0L Duramax diesel producing 305 horsepower and 495 lb-ft of torque. According to GM, it’s smoother, quieter, and more capable than before. Also based on GM’s claims, ride and handling improvements reduce body roll and vibrations, especially with Magnetic Ride Control and Air Ride Adaptive Suspension.

On the outside, all trims benefit from refreshed lighting and bolder fascia designs. For the RST and High Country, 24-inch wheels are now on the menu. Inside, materials and design details are improved across the lineup, especially in the High Country, which now features authentic wood and premium leather.

My RST tester featured the creamy-smooth 6.2L V8 as well as the top suspension configuration offered. While the former did just fine, the latter severely underdelivered. Partly to blame are the newly available 24-inch wheels.

Why You Should Buy the 2025 Chevrolet Suburban

Ultimate Utility: With 1,175 litres of cargo space behind the third row (over 2,600 litres with it stowed), there’s nothing quite like the Suburban for families who pack heavy or travel often. No matter if it’s hockey gear or a week’s worth of camping equipment, it fits. Always.

V8 Smoothness or Diesel Muscle: The optional 6.2L V8 remains a buttery powerhouse with a burly soundtrack. The new diesel offers more real-world torque and impressive highway fuel economy, an important consideration especially if trailering is part of your lifestyle.

Tech Overhaul Done Right: The new infotainment setup is responsive, easy to use, and finally competitive with luxury-brand rivals. Apple CarPlay works seamlessly, and the new camera system (with remote viewing via the app) adds a layer of security.

Big Rig Presence: Let’s be honest: it still looks badass. Square-shouldered, massive, and proud of it. The 2025 updates modernize the look without losing what makes the Suburban such an icon. The 24-inchers play a role here.

Improved Ride Quality (Mostly): With the right wheels and suspension combo, the Suburban can glide comfortably over rough roads. The adaptive air suspension and magnetic dampers offer notable composure. Remember to avoid the oversized 24-inch wheels if comfort is a priority.

Why You Should Not Buy the 2025 Chevrolet Suburban

Six-Figure Expectations, Budget Details: For over $110,000, our test unit lacked cooled front seats and featured manual tilt/telescoping steering. These are oversights that stand out when rivals offer these as standard for less money. GM’s parts-bin cost-cutting still shows through in some odd places.

Big Wheels, Bigger Ride Compromise: The available 24-inch wheels look killer, as stated, but seriously undermine ride quality. The magnetic dampers struggle to keep up with the mass, resulting in a disturbingly unsettled ride over broken pavement.

Fuel Economy (Gasoline V8): Not news, but even with cylinder deactivation and highway cruising, the 6.2L V8 won’t win any eco awards. Expect 14–16 L/100 km in mixed driving unless you go for the diesel.

Large in Every Way: This thing is huge. Urban dwellers beware as it’s a handful in tight parking garages and narrow streets. Towing, hauling, and road-tripping? Yes. Parallel parking downtown? That’s what all the cameras are really for.

Conclusion

The 2025 Chevrolet Suburban doesn’t try to reinvent itself because it doesn’t need to. It’s still the undisputed king of cavernous full-size three-row SUVs, now with a tech and design refresh that keeps it current. It rides better (as long as you avoid the 24s), tows with confidence, and can be specced with one of the most refined diesel engines in its class (having reviewed the previous gen in other models).

If you’re shopping for a full-size SUV that can genuinely replace a minivan, truck, and luxury cruiser in one fell swoop, the Suburban remains a compelling, if pricey, package. You’ll grumble about the lack of a few premium touches, but you’ll never complain about running out of space.

For my money? I’d spec a Yukon XL AT4 Ultimate with the Duramax, but there’s no denying the 2025 Suburban stays true to its roots and still delivers exactly what big families need… and want.
