2026 Chevy Tahoe Specs and Dimensions AR

This page is the hard-numbers reference for the 2026 Chevrolet Tahoe: powertrain outputs, exterior and interior dimensions, capacity, fuel economy and warranty. It is the page Northwest Arkansas shoppers open when the question is a figure, not a feeling. For help choosing, see the Overview and the All Trims Compared pages.

Engine Specifications

Three engines share a 10-speed automatic. The base 5.3L V8 covers the way most families drive; the 6.2L V8 is the strongest gas engine; and the 3.0L Duramax turbo-diesel makes the most torque of the three and is built for range.

Rear-wheel drive is standard across the lineup; four-wheel drive is available on every trim and is standard on the Z71. The 5.3L V8 runs on regular 87-octane fuel; Chevrolet recommends premium for the 6.2L V8.

Exterior Dimensions

The Tahoe rides on a 120.9-inch wheelbase and measures 211.3 inches long, 81.0 inches wide without the mirrors and 93.6 inches across with them extended. That mirror width is worth knowing before a tight garage bay or the parking deck at XNA: fold the mirrors and it drops into a standard bay, but it is a wide vehicle in a compact space.

Ground clearance is 8.0 inches on every trim, including the Z71; the available Four-Corner Air Ride Adaptive suspension on the RST, Z71 and High Country raises that to as much as 10.0 inches. The gain comes from the air ride, not the badge.

Interior Dimensions and Cargo

The Tahoe seats up to nine when the LS is ordered with its front bench; most trims seat eight, and second-row captain's chairs bring the count to seven. Behind the third row sits 25.5 cubic feet of cargo, 72.5 cubic feet opens up behind the second row, and folding both rear rows clears 122.7 cubic feet — room for the whole family and the gear for a weekend run out US-412.

The full deep dive on space and seating lives on the Cargo and Seating page.

Capacity and Capability

Properly equipped, the Tahoe tows up to 8,400 pounds, and that ceiling belongs to one build: the 5.3L V8 with rear-wheel drive and the Max Trailering Package. The 6.2L V8 is rated at 8,200 pounds. The Duramax diesel carries the same 8,200-pound rating. Curb weight for the 5.3L configuration is 5,705 pounds against a 7,600-pound GVWR, and the fuel tank holds 24.0 gallons.

The number breaks down by engine and drivetrain on the Towing and Payload page.

Wheels, Tires and Brakes

Wheel diameter climbs with the trim, from 18-inch on the volume trims to 22-inch on the appearance and flagship trims.

Fuel Economy and Range

The standard 5.3L V8 with rear drive is rated 15 mpg city, 20 highway, 17 combined. The Duramax diesel trades some of that around for range, returning 22 city and 26 highway with rear drive — good for up to 624 highway miles on the 24.0-gallon tank, enough to run the I-49 corridor from Fayetteville up to Bentonville for a week of commuting without a fill-up.

The Duramax deep dive lives on the Duramax Diesel page. Ratings are EPA estimates and vary with how and where you drive.

Key Features by Trim

A compact decision grid of the features shoppers ask about most. The full per-trim breakdown lives on the Trims Compared page.

Legend: S = standard, O = available, — = not standard equipment.

Safety and Compliance

Chevrolet Safety Assist is standard across the lineup, bundling automatic emergency braking, lane keep assist, a following-distance indicator and more. In federal testing the 2026 Tahoe earns a 5-star overall NHTSA rating, with a 3-star rollover score. Confirm the ratings for the exact configuration before purchase.
