When you are a guest at a destination wedding, and the bride asks you to bring a large vehicle that can be used to transport people, decorations, and other miscellaneous boxes, there is only one vehicle for the job: the 2026 Chevrolet Suburban. Chevy’s longest and largest SUV packs more interior space than any other passenger vehicle on the market (tied with the GMC Yukon XL), making it the obvious choice to bring to the wedding.

Pros & Cons
- More space than anything in its class
- Class-leading ride and handling
- Great tech and driver assistance
- Rivals tow more and accelerate quicker
- Expensive, especially at the high end
- V8 engines are thirsty
This being a special day, we couldn’t settle for a Suburban in one of its more “suburban” trim levels. That’s why we opted for the top High Country trim level with the 6.2-liter V8 engine. The Suburban is currently in its twelfth generation, having last been fully redesigned alongside its shorter Tahoe sibling (currently in its fifth generation) back in 2021. Both models were given a facelift for the 2025 model year, but are mostly carried over into 2026. The only notable changes include a new RST Dark Essentials appearance package, Cabin Glance interior camera, expanded wheel and color options, and the ability to ditch the key fob for a key card.
Exterior Looks: Pedestrian To Premium
Strengths
Weaknesses
- Six trims with different personalities
- Z71 looks tough and High Country is luxurious
- So many wheel options
- Only six exterior colors
- Wheels are hugely expensive
- Z71 could be more extreme
Chevy sells the Suburban in six trim levels, ranging from the utilitarian LS up to the decadent High Country. The LS and LT trims look pretty plain, riding on Bright Silver 18-inch wheels, though a number of 20- and 22-inch accessory wheels are available, ranging from $1,100 up to $3,595.
For a sportier look, the RST brings 22-inch bright machined High-Gloss Black wheels and a unique front fascia. Off-road enthusiasts will enjoy the Z71 with its smaller 20-inch wheels wrapped in all-terrain tires, front and rear skid plates, and red recovery hooks. Lastly, the Premier starts to get more luxurious with 20-inch polished wheels, but the High Country takes the Suburban into GMC and Cadillac territory with standard 22-inch wheels, available 24-inch wheels, and the most blingy appearance.
The Suburban is essentially the same vehicle as the Tahoe, albeit longer to accommodate more passenger and cargo space. Both are body-on-frame SUVs, but the Suburban stretches 226.3 inches in length compared to the Tahoe’s 211.3 inches. The Suburban also has an increased wheelbase of 134.1 inches, while the Tahoe is only 120.9 inches between its axles. All of that extra length is dedicated to third row passengers and having more cargo space when the third row is in-use.
Interior & On-Board Technology: What Can’t It Fit?
Strengths
Weaknesses
- Enough room for everything and everyone
- Google-based infotainment is handy
- The sliding armrest is useful
- Some features left out for GMC and Cadillac
- Bose audio doesn’t sound great
- High trims only seat seven
Chevy gave the Suburban a major interior glow-up for the 2025 model year, which included a standard 17.7-inch touchscreen to replace the outgoing eight-inch unit. Other carryover improvements from last year include a redesigned center console with more storage (and an available power-sliding option), a new steering wheel, and more premium decor on the upper trims. The High Country trim we tested is particularly snazzy with new wood decor and a unique Black/Mocha leather combination.

Buyers of the Suburban will mainly love its ability to haul seven or eight passengers comfortably and still have room for cargo behind the third row, a task even the Tahoe struggles with. During the wedding weekend, we packed the Suburban full of flower centerpieces, groomsmen, and other wedding decorations that needed to go from the hotel to the venue; they all fit with ease. 144.5 cubic feet is more than any other SUV on sale (tied with the Yukon XL), so if you need more space, it will require a minivan.

Infotainment: Solid Input, Weak Output
Every Suburban gets a massive 17.7-inch touchscreen with built-in Google compatibility, as well as Android Auto and Apple CarPlay. This system is easy to use, either by voice or by touch, and Chevy retained enough physical buttons for climate control. We also love that Chevy includes standard surround-view cameras, which are important on such a massive vehicle and came in handy when driving around the historic roads in Saint Augustine, Florida, where the wedding took place. If we have one complaint, it’s with the audio system in the Suburban. The base setup only includes six speakers, and even the upgraded 10-speaker Bose CenterPoint Surround system in our High Country tester was unimpressive, lacking any mid-level punch. As a plus, we did enjoy the available rear media system, which features built-in streaming platforms such as Disney+ and Hulu.
Performance: A Family Boat
Strengths
Weaknesses
- Super Cruise makes family trips less stressful
- Duramax Diesel is the fuel economy king
- Magnetic Ride Control can not be beat
- V8 engines have less power than rivals
- Base engine is lackluster in the segment
- Competitors can tow more
Chevy offers three engines in the Suburban – a 5.3-liter gas V8, a 6.2-liter V8, or a 3.0-liter Duramax turbo-diesel inline-six – though not every trim is available with every motor. The 5.3-liter V8 comes standard on every trim except for the High Country, which upgrades to the bigger 6.2-liter engine or the Duramax for a small upgrade fee.
You can get only the LS with the base V8, while the LT can be upgraded with the Duramax. The Z71, RST, and Premier trims can be equipped with any of the three engines when optioned with 4WD (the Premier RWD cannot get the 6.2), but Chevy charges a lot to upgrade, depending on trim. Chevy’s pricing ranges wildly, but the Duramax costs around $4,000, while the 6.2 can add as much as $8,000 to $10,000.

Performance Impressions
Our High Country tester featured the standard (for this top level trim) 6.2-liter V8 engine with optional 4WD. A vehicle like this does not have launch control, but using a combination of brake-torquing, Sport Mode, and traction control off, we recorded a zero-to-sixty run in 6.22 seconds. That’s quicker than the 2025 GMC Yukon AT4 Ultimate (6.4 seconds) and 2025 Cadillac Escalade Sport Platinum (6.68 seconds) we tested, both of which have the same 6.2-liter V8 engine. The Suburban was still slower than both versions of the Nissan Armada, including the 2026 Pro-4X (6.17 seconds) and 2025 Platinum Reserve RWD (6.16 seconds), thanks to their gutsy twin-turbo V6 engine.
Having just tested Chevy’s 5.3-liter V8 in a Silverado 1500, we came away unimpressed with its sound and refinement. The 6.2-liter V8 is far smoother and delivers better passing power, but as the numbers reveal, Chevy’s turbocharged rivals are quicker and outmatch its 7,700-pound towing capacity. If we were buying a Suburban, the Duramax diesel is the engine we’d want. It’s refined, gutsier than ever after GM’s latest enhancements, and it’s by far the most fuel efficient in this segment. On a road trip, you can do over 700 miles without stopping in a diesel Suburban. What will last longer, the fuel tank or your children’s bladders? Later this year, Chevy will reveal its next-generation Silverado with new V8 engines, which will eventually end up in the Suburban. We hope GM also solves the recall issue, which has plagued the 6.2-liter engine.
Ride and Handling
The High Country trim is the most luxurious Suburban, equipped with Chevy’s Magnetic Ride Control dampers and four-corner Air Ride Adaptive Suspension. We’d still describe the handling as truck-like, as with most body-on-frame SUVs, but these High Country additions improve the Suburban’s road manners significantly. In fact, this is among the most pleasant-riding vehicles in its segment, with more body control and less wheel hop than you get in competitors.
For tight maneuvers, the surround-view camera system comes in handy, though we wished the Suburban had the same rear-wheel steering feature found in GM’s electric SUV models to navigate St. Augustine’s tight cobblestone streets. On the highway, the size doesn’t matter as much, and we could relax as Super Cruise effortlessly took us to and from our destination wedding with zero drama. This remains one of our favorite driver assist systems on the market.
Fuel Economy

Don’t expect Chevy’s biggest SUV to be a fuel sipper, unless you are willing to pay a little more for diesel. The base 5.3-liter V8 isn’t too thirsty thanks to cylinder deactivation, managing 15/20/17 mpg (city/highway/combined) with 2WD and 14/19/16 mpg with 4WD. Opting for the 6.2-liter V8 drops the fuel economy down to 15/19/16 mpg with 2WD and 14/18/16 mpg with 4WD.
Though the diesel fuel will cost more at the pump, the Duramax inline-six is by far the most efficient, with EPA ratings of 21/26/23 mpg with 2WD and 20/26/22 mpg with 4WD. Not even the hybrid Toyota Sequoia (21/24/22 mpg) can match it.
Verdict & Pricing: King Of Common
Price creep and inflation are two very real trends, so if you want a giant SUV that can do it all, you need to pay to play. $63,700 is the starting price for a 2026 Chevy Suburban LS with a 5.3-liter V8, and you’ll pay more if you want 4WD. The LT doesn’t look much different, but adds a nicer interior and more features for $66,700, while the RST dresses this big brute with a sportier appearance starting at $71,700. If you plan to take your family off the pavement, the Z71 trim starts at $73,700, and the Premium is $78,600, but can go up significantly from there if you want one of the upgraded engines. That leaves us with the High Country, which starts at $83,700, but came equipped with $12,555 worth of options that brought our tester’s price to $100,800 as-tested (including a $2,595 destination charge).

We know times are tough, but it’s hard to believe we live in a world where a Chevy Suburban, not a Yukon Denali or Cadillac Escalade, now costs six figures. It’s just a mental hurdle that’s tough to overcome. Chevy mostly justifies the price tag, aside from a lack of massage seats, no ventilated second row seats, and a lackluster audio system. All of these complaints are rectified by the GMC and Cadillac siblings, albeit at an even higher cost. You could save some money with one of the competitors, like a Nissan Armada, but it won’t drive as well, nor carry as much stuff. If you want the best,
