The 2025 Suburban gets a robust update without losing its character. The highlights include:

    New exterior styling: Angled headlights, a new grille, and new wheels.

    Enhanced technology: A huge new 17.7-inch touchscreen and an 11-inch digital driver display are now standard.

Improved diesel engine: The 3.0L Duramax diesel gets more power and is now available on off-road trims.

    Super Cruise: Chevy’s hands-free driving technology is now available on more trims.

It still appears quintessentially Suburban — just crisper, smarter, and bolder.

You have three good engine options, depending on your needs:

5.3L V8 – 355 horsepower, 383 lb-ft torque (standard on most models).

    6.2L V8 – 420 horsepower, 460 lb-ft torque (optional on High Country).

    3.0L Duramax Turbo-Diesel I6 – Now with 305 horsepower and 495 lb-ft torque.

All are matched to a 10-speed automatic transmission, and rear-wheel drive (RWD) or four-wheel drive (4WD) is available. Chevrolet Suburban 2025

Fuel economy is. Well, what you’d expect from a body-on-frame, full-size SUV — but the diesel is more economical than you might think.

    5.3L V8 (RWD): ~15 mpg city / 20 mpg highway

    6.2L V8 (4WD): ~14 mpg city / 18 mpg highway

    3.0L Diesel (RWD): ~21 mpg city / 27 mpg highway

If you’re doing highway driving or long-distance hauling, the diesel is the route to take for fuel efficiency. Chevrolet Suburban 2025

It depends on how you equip it, but the Suburban will seat 7, 8, or 9 individuals:

    Bench seating in the second and third row = up to 9 seats.

Captain’s chairs in the second row = more upscale 7-seat configuration. 

    Most choose 7 or 8, based on family requirements.

Headroom and legroom are ample in all three rows, and adults can comfortably sit in the third row. Chevrolet Suburban 2025

The Suburban is still the cargo king. There’s a massive 41.5 cubic feet behind the third row — space for big suitcases, coolers, strollers, or sports gear.

    With 3rd row folded: 93.8 cubic feet

    With 2nd + 3rd row folded: 144.7 cubic feet

That’s more space than most crossovers even have with their seats folded. It’s cavernous. Chevrolet Suburban 2025

Yes — very good. When properly equipped:

    Maximum towing: 8,300 pounds

 Available Max Trailering Package: Integrated brake controller, extra cooling, and trailering camera views.

Camper, boat, or horse trailer, the Suburban isn’t afraid to tow its weight (and then some). Chevrolet Suburban 2025

There are six trims Chevy offers:

    LS – No-frills but well-equipped.

LT – Additional tech and convenience features are added.

    RST – Sportier look, blacked-out trim.

    Z71 – Off-road functionality features like skid plates, all-terrain tires.

    Premier – Luxury-lite, more safety and convenience features.

    High Country – Top trim, comes with the 6.2L V8 and premium trim.

There’s a personality for every trim — from family hauler to executive shuttle to trail-ready bruiser. Chevrolet Suburban 2025

The 2025 update brings a substantial leap forward inside:

    New digital displays: Standard 17.7-inch touchscreen and 11-inch digital gauge cluster.

    Material quality: Improved throughout, with soft-touch surfaces, contrast stitching, and wood or aluminum accents available.

Quiet cabin: Premier and High Country are especially well-insulated.

It’s roomy, upscale, and thoughtfully designed — even the cupholders are intelligently placed. Chevrolet Suburban 2025

Chevy Safety Assist is standard on every trim level and includes:

    Forward collision alert with automatic emergency braking

    Lane keep assist

    Front pedestrian braking

Following the distance indicator

    Intelli Beam automatic high beams

Available or optional safety technology features are:

    Blind zone steering assist

    Rear pedestrian alert

    HD surround vision (360° camera)

    Super Cruise hands-free driving (on Premier/High Country)

It’s one of the safest Suburbans yet. Chevrolet Suburban 2025

If you do a lot of highway time, yes. Super Cruise is GM’s hands-free highway driving on eligible highways. You can take your hands off the wheel on long drives, as long as you’re attentive and on mapped roads.

It’s:

    Smooth and confident

    Uses cameras and radar to stay centered in the lane

Available on Premier/High Country trims only

It’s a lifesaver for heavy drivers. Chevrolet Suburban 2025
