2026 model shown.

The 2027 Chevy Tahoe is 211.3 inches long and 93.6 inches wide including mirrors, with three regular engines from 305 to 420 horsepower. Reading and Schuylkill Haven buyers get a 24-gallon tank, three-row seating and up to 122.7 cubic feet of cargo capacity. The Tahoe overview covers the whole SUV, while trim pricing and equipment separate the six models.

2027 Tahoe Engine Specifications

Engine availability across the lineup

The 5.3L is standard on LS, LT, RST, Z71 and Premier. High Country starts with the 6.2L, which is also available on RST, Z71 and Premier. The Duramax is available on LT, RST, Z71, Premier and High Country. RST Performance Edition uses its own 6.2L tune and brake package, so its output is not the figure for every RST with a 6.2L.

Torque and horsepower describe different parts of the engine choice. The Duramax has 112 lb-ft more torque than the 5.3L, while the 5.3L has 50 more horsepower than the diesel. Both use ten transmission speeds. The 6.2L moves the regular V8 output to 420 horsepower, with the premium-fuel recommendation as part of that ownership choice.

Exterior Dimensions for Reading Parking and Garages

The 81.0-inch body measurement and 93.6-inch mirror measurement answer different space questions. Mirrors add to the width when they are extended; the wider figure is the relevant physical span at a narrow entrance. Chevrolet publishes a height range rather than one height for every trim and suspension. Ground clearance is about 8 inches nominally, with suspension and ride-height settings affecting the space underneath. Available Four-Corner Air Ride adjusts vehicle height.

The curb-weight range describes different Tahoe models before passengers and cargo. GVWR is the loaded-vehicle rating, not an additional load allowance. The 7,600-pound example above belongs to the specified Z71 configuration. The actual vehicle’s certification and load labels determine its ratings and carrying allowance; those labels account for the equipment installed on that Tahoe.

Interior Dimensions and Cargo Space near Reading

The second row’s 42.0 inches of legroom is close to the front row’s 44.5 inches, while the third row supplies 34.9 inches. Shoulder room remains 62.7 inches in the back row. The three rows therefore offer different amounts of leg and hip space even though the cabin is full width. For a Lebanon household with adult passengers in more than one row, legroom and seating layout are separate parts of the cabin choice.

The maximum 122.7-cubic-foot figure requires both rear rows to be folded. With the third row upright, the cargo space is 25.5 cubic feet. Folding that row adds room for larger items while preserving the second row. Tahoe’s second and third rows fold flat, and split seatbacks allow a mix of occupied seats and longer cargo when the remaining seating positions are suitable.

An eight-seat layout uses a second-row bench. Captain’s chairs create the seven-seat layout and are available on LT, RST and Z71, with Premier and High Country including them. LS offers a front bench for nine seats. Seat material and seat count are distinct: the second-row arrangement changes the passenger number, while heating, ventilation and upholstery change comfort.

Capacity, Towing and Trailering Equipment

The maximum tow figure includes an engine, drivetrain and package requirement. A larger-displacement engine does not automatically increase that number. The load carried in the Tahoe also matters: people, cargo and trailer tongue weight contribute to the vehicle’s load. Available camera views and the in-vehicle trailering app support hitching and monitoring; they are separate from the vehicle’s rated mechanical capacity.

For a Pottsville household carrying passengers as well as a trailer, the actual load label governs how those loads combine. GVWR and trailer rating describe different limits. A properly equipped vehicle’s trailering information also includes the combination weight rating and hitch requirements. The Tahoe service page covers the different maintenance schedule that applies under consistent towing use.

Wheels, Tires and Brakes

Wheel diameter, tire type and brake equipment are separate specifications. Z71’s all-terrain tire package belongs with its skid plate, front-fascia design and two-speed transfer case. RST Performance Edition pairs its 433-hp engine with Brembo heavy-duty front brakes. Standard Tahoe braking uses four-wheel discs with ABS; larger optional wheels are not themselves a towing-capacity upgrade.

2027 Tahoe EPA Fuel Economy and Range

The Duramax’s 24 combined mpg in 2WD compares with 17 for the 5.3L 2WD. In 4WD, the corresponding combined figures are 22 and 17. Chevrolet’s available 624-mile maximum highway range belongs to the diesel’s highway estimate, not a combined-driving promise or a towing-range estimate. Trailer load, traffic, temperature and driving conditions change real fuel use.

For longer US-222 drives around Reading and Allentown, the diesel’s highway rating addresses a different use than short local trips. For a Bally household traveling toward Limerick on US-422, the V8’s regular-gas requirement and the diesel’s higher combined mpg are different ownership considerations. The engine-specific fuel grade remains part of the comparison even when combined mileage happens to be equal between two engines.

Key Features by Tahoe Trim

These are selected decision features rather than a complete package list. The 17.7-inch touchscreen and wireless smartphone integration belong to the shared Tahoe equipment. Front-seat ventilation appears on RST, Premier and High Country, while the 6.2L is included with High Country and offered on several other trims. The trim-by-trim breakdown connects each starting price to these equipment choices.

Safety and Driver Assistance

Adaptive Cruise Control and HD Surround Vision are listed with the LS. Tahoe also has automatic emergency braking, Reverse Automatic Braking and Rear Cross Traffic Braking, with additional assistance such as Blind Zone Steering Assist with Trailering available. Super Cruise is a separate available system on eligible trims. Camera views and driver assistance vary with the vehicle’s equipment, and all require an attentive driver.

Warranty Coverage and Included Maintenance

Factory warranty covers qualifying defects under its terms, while routine maintenance follows the service schedule. The first included visit combines three specific services and has a first-year time condition. Outten’s service appointment page connects the Tahoe to the dealership, and the gas and diesel service schedule lists the recurring maintenance milestones.

Tahoe Specifications FAQs

Is the 93.6-inch Tahoe width a body-only measurement?

The 93.6-inch measurement includes the mirrors. Body width without mirrors is 81.0 inches in the 2027 Z71 specifications. Overall length is 211.3 inches, and Chevrolet gives a 75.8–76.8-inch height range. The mirror-inclusive width and the body height cover two different parts of the Tahoe’s exterior size.

What are the Tahoe’s three cargo-volume measurements?

Cargo room is 25.5 cubic feet behind the third row, 72.5 with the third row folded and 122.7 with both rear rows folded. The largest figure describes a two-person front-row cargo arrangement rather than a fully occupied three-row cabin. Both rear rows fold flat.

How much third-row legroom does the 2027 Z71 have?

The Z71 specifications list 34.9 inches of third-row legroom, alongside 38.2 inches of headroom and 62.7 inches of shoulder room. Second-row legroom is 42.0 inches. The two rows offer different leg space even though both occupy the full-width three-row Tahoe cabin.

Which 4WD Tahoe engine has the highest combined EPA rating?

The 3.0L Duramax 4WD is rated at 22 combined mpg, with 20 city and 24 highway. The 5.3L 4WD is rated at 17 combined, and the 6.2L 4WD at 16. These are EPA estimates for the stated powertrains, with actual mileage affected by use.

Does Tahoe curb weight mean the same thing as GVWR?

Curb weight describes the vehicle before added passengers and cargo; GVWR describes its rated loaded weight. Chevrolet gives a 5,509–5,882-pound curb-weight range across Tahoe models. The example Z71 4WD has a 7,600-pound GVWR, while its actual load label governs the carrying allowance for that vehicle.

Is 624 miles a towing-range estimate?

The 624-mile figure is Chevrolet’s EPA-estimated maximum highway range for the available diesel. It is not a towing-range figure. The Duramax 2WD rating is 26 highway mpg with a 24-gallon tank; passengers, trailer load, weather and traffic change the fuel used on a real drive.

Which Tahoe has the 433-hp engine specification?

The RST Performance Edition supplies 433 horsepower and 467 lb-ft from its 6.2L V8, with Chevrolet Performance induction and exhaust. The regular 6.2L produces 420 horsepower and 460 lb-ft. Brembo heavy-duty front brakes are another part of the Performance Edition equipment.

Are all Tahoe fuel tanks the same as the Suburban’s?

The short-wheelbase Tahoe uses a 24.0-gallon fuel tank. The shared owner’s manual lists a different 28.0-gallon tank for the long-wheelbase vehicle. Tahoe’s fuel economy and range figures must be paired with its own tank and engine rather than another SUV’s larger fuel capacity.
