2027 Suburban Specs NWA AR

Engine and Drivetrain Specifications

LS, LT, RST and Premier are offered in 2WD and 4WD configurations; Z71 and the listed High Country base configuration use 4WD. Engine availability and drivetrain must be checked together when selecting equipment.

The 5.3L V8 uses regular 87-octane gasoline. Chevrolet recommends premium 91-octane gasoline for the 6.2L V8. The Duramax engine uses diesel fuel. Follow the fuel instructions for the vehicle you select.

Exterior Dimensions and Parking

A garage can accommodate the vehicle’s length yet leave too little working room behind it. Measure with storage shelves, a closed garage door and the space you need to walk around the SUV. If your Centerton driveway has a tight turn, a low-speed test matters more than the parking-space length alone.

Interior Dimensions and Seating

Eight-passenger seating is standard, with seven- and nine-passenger arrangements available. Actual seating depends on the installed front and second-row seats. Check headroom and access in the vehicle you intend to buy, including its roof equipment.

Cargo Capacity by Seat Position

Cargo volume describes space, not allowable weight. Secure loads and keep them within the vehicle’s payload and axle limits. For tall or rigid objects, measure the object and physically check the loading opening; cubic feet alone cannot settle fit.

Towing, Payload and Weight Labels

Match a trailer to the specific vehicle, not just the engine’s horsepower. Record the engine, drivetrain, trailering package and hitch equipment, then use the vehicle’s trailering information to check the loaded trailer.

The passenger-and-cargo label establishes the allowance for that vehicle. Passengers, accessories, luggage and trailer tongue weight consume it. The certification label also gives gross vehicle and axle weight ratings; those limits apply together.

For a loaded family trip toward Beaver Lake, weigh or realistically account for the people and equipment you actually bring. A brochure’s maximum trailer figure is not the remaining capacity after you fill the cabin. Send our team your trailer details so we can review a specific Suburban with you.

Wheels, Tires and Brakes

Tire dimensions and replacement choices should follow the actual tire and wheel combination on your vehicle.

Fuel Economy and Ownership Planning

Compare the window-sticker fuel-economy label for the exact engine and drivetrain you are shopping. Use the same annual mileage and fuel-price assumptions for each vehicle; mixing a gasoline estimate with a diesel fuel price makes a cost comparison misleading.

The Z71 4WD specification reference lists a 28-gallon fuel tank. Tank capacity is not a promised driving range: driving conditions, load and usable fuel affect how far a trip between stops will be.

Key Features and Safety

A 17.7-inch center touchscreen, 11-inch driver display, Adaptive Cruise Control and HD Surround Vision are standard highlights. Available Super Cruise, a Rear Camera Mirror and Head-Up Display depend on trim and equipment.

Use the trim guide to distinguish standard equipment from available features. Driver aids have operating limits and do not replace attentive driving.

Warranty and Service

Chevrolet’s bumper-to-bumper limited warranty is three years or 36,000 miles, whichever comes first. Coverage, exclusions and powertrain terms should be reviewed in the warranty information for your engine and vehicle. Routine maintenance and a limited warranty serve different purposes.

See Chevrolet warranty information and our Suburban maintenance guide to prepare for ownership.

Specifications in Practice

For Fayetteville households carrying passengers in every row, cargo volume behind the third row deserves more attention than maximum cargo volume. For a parking decision, measure mirrors and usable garage space rather than relying on body width. For towing, start with actual labels and a loaded trailer.

The Tahoe comparison puts the two SUVs’ size and cargo figures on the same basis.

Specification FAQs

Does the 144.5-cubic-foot figure apply with passengers in every row?

No. It is the maximum cargo volume with the rear rows folded. With the third row upright, Suburban has 41.5 cubic feet behind it.

Which width should I use for my garage opening?

The 93.6-inch mirror-inclusive width is more useful than the 81.0-inch body width for initial planning. Measure the actual vehicle and opening with enough clearance for careful entry.

Can I calculate payload by subtracting a generic curb weight from GVWR?

Use the passenger-and-cargo label on the actual vehicle. Equipment changes vehicle weight, so a generic subtraction can misstate the allowance you have available.
