The 2027 Chevrolet Tahoe carries three available engines topping out at 433 hp, a maximum 122.7 cubic feet of cargo volume, up to 8,400 pounds of towing capacity, and a 3-year/36,000-mile bumper-to-bumper warranty. Every figure below is sourced and dated. For trim pricing and equipment, see the trims page; for the full model walkthrough, see the 2027 Tahoe overview.

The 2027 Tahoe carries the same body, glass and sheet metal as the 2026 model, a refresh year rather than a redesign, so every dimension below applies to both model years unless a table row says otherwise. That matters for a Tulsa buyer cross-shopping a leftover 2026 against a new 2027: the two are the same size, the same weight class and fit the same garage.

Engine Specifications

Engine	Horsepower	Torque	Transmission
5.3L EcoTec3 V8	355 hp	383 lb-ft	10-speed automatic
6.2L EcoTec3 V8	420 hp	460 lb-ft	10-speed automatic
6.2L V8 (RST Performance Edition tune)	433 hp	467 lb-ft	10-speed automatic
3.0L Duramax turbo-diesel	305 hp	495 lb-ft	10-speed automatic

Every engine pairs with the same 10-speed automatic. The 5.3L EcoTec3 V8 uses Dynamic Fuel Management, which deactivates cylinders under light load to save fuel without a driver noticing the shift, and it is the engine underneath the Tahoe's headline 8,400-pound tow rating when paired with rear-wheel drive and the Max Trailering Package. The 6.2L EcoTec3 V8 is standard equipment on High Country and available on RST, Z71 and Premier for buyers who want more passing power without changing trims. The RST Performance Edition's tune of that same 6.2L adds Chevrolet Performance induction and exhaust components on top of the standard hardware to reach its 433-hp peak, the highest output Chevrolet offers on a 2027 Tahoe. The 3.0L Duramax turbo-diesel trades peak horsepower for torque and range, and for 2027 it can be paired with Super Cruise hands-free driving for the first time. Fuel type is gasoline for the two EcoTec3 V8s and diesel for the Duramax; all three use the Tahoe's shared 24.0-gallon fuel tank.

Exterior Dimensions

Dimension	Measurement
Overall length	211.3 in
Wheelbase	120.9 in
Width, without mirrors	81.0 in
Width, with mirrors	93.6 in
Height	76.3 in
Ground clearance, standard	8.0 in
Ground clearance, Four-Corner Air Ride Adaptive Suspension	up to 10.0 in
Curb weight (5.3L configuration)	5,705 pounds
Gross vehicle weight rating (GVWR)	7,600 pounds

Width with mirrors, 93.6 inches, is the number that matters for a standard single-car garage bay, which typically runs 9 to 10 feet wide with the door frame included; most Tulsa garages clear it with room on both sides, but a narrower older bay near downtown is worth measuring first. The available Four-Corner Air Ride Adaptive Suspension raises ground clearance from 8.0 to as much as 10.0 inches, useful for a gravel approach or a steep driveway apron rather than daily street parking.

Interior Dimensions and Cargo

Spec	Measurement
Seating capacity	up to 9 (LS front bench); up to 8 on every other trim
Cargo behind 3rd row	25.5 cu ft
Cargo behind 2nd row	77.5 cu ft
Max cargo, both rear rows folded	122.7 cu ft

Behind the third row is grocery-and-gear space for a normal week; fold the third row and the Tahoe opens up to 77.5 cubic feet, enough for a bulk warehouse-club run off US-75 or flat-pack furniture. Fold both rear rows and the maximum climbs to 122.7 cubic feet, enough for a full-size mattress or a complete move without a second trip. Seating tops out differently depending on trim: only the LS carries the front bench seat that opens up a 9-passenger count, while every other 2027 Tahoe trim uses front bucket seats and seats up to 8. A Tulsa family cross-shopping trims for a specific carpool number should confirm that seat count before assuming it carries across the whole lineup.

Capacity and Towing by Configuration

Configuration	Max Towing
5.3L V8, rear-wheel drive, Max Trailering Package	8,400 lbs
6.2L V8 configuration	8,200 lbs
Duramax diesel configuration	8,200 lbs

The 8,400-pound maximum is specific to one build: 5.3L V8, rear-wheel drive, with the Max Trailering Package installed. Stepping to the 6.2L V8 changes the number to 8,200 pounds, and choosing the Duramax diesel instead lands at that same 8,200-pound figure, a 200-pound gap from the 5.3L build worth confirming against the exact vehicle on the lot rather than assuming the headline figure applies to every build. An in-vehicle trailering app and up to 14 camera views come standard for hitching and backing, which turns solo hitching in a driveway off South Memorial Drive into a one-person job instead of two, and Super Cruise now holds hands-free assistance active with a trailer attached on a compatible highway stretch.

Wheels, Tires, and Brakes

Trim	Wheels	Notes
LS	18-in Bright Silver-painted aluminum	All-season tires standard
RST	Available 24-in machined and painted Carbon Flash Metallic	All-season tires
Z71	20-in all-terrain Goodyear Wrangler Territory	Standard; built for off-pavement grip
High Country	Available 24-in bright machined	Magnetic Ride Control standard
RST Performance Edition	Standard performance wheel package	Brembo heavy-duty front brakes

Wheel size climbs with trim and shifts purpose along the way: LS's 18-inch wheels and all-season tires are built for everyday grip and a smoother ride over Tulsa's rougher stretches of pavement, RST's available 24-inch wheels trade a little ride comfort for street presence, and Z71's 20-inch all-terrain Goodyear Wrangler Territory tires are sized specifically for a gravel road or a trail past Sand Springs rather than a showroom look. The RST Performance Edition is the one trim built around stopping power rather than wheel size: its standard Brembo heavy-duty front brakes are sized for repeated hard stops, a genuinely different engineering target than the rest of the lineup.

Fuel Economy and Range

Engine	Drive	City	Highway	Combined
5.3L V8	RWD	15	20	17
5.3L V8	4WD	15	19	17
6.2L V8	RWD	15	20	17
6.2L V8	4WD	14	18	16
3.0L Duramax	RWD	22	26	24
3.0L Duramax	4WD	20	24	22

These are 2026 EPA-certified ratings for engines carried unchanged into 2027; Chevrolet has not yet published a separate 2027 certification (fueleconomy.gov, checked 2026-09-16). The Duramax diesel is the clear highway-mileage leader, with an estimated range of up to 624 miles on a single 24.0-gallon tank, OEM-stated for 2027.

Safety and Compliance

Standard safety and driver-assistance equipment includes Adaptive Cruise Control and HD Surround Vision, which uses up to 14 camera angles for parking, hitching and tight maneuvering around Tulsa parking garages. Available Super Cruise adds hands-free highway driving assistance on a compatible stretch of road, holding lane position and following distance automatically, and for 2027 it can be ordered with the Duramax diesel for the first time. The 2027 Tahoe has earned J.D. Power's "America's Most Dependable Large SUV" recognition for four consecutive years, a reliability track record that carries directly into resale value for a buyer planning to keep the vehicle a decade or trade it in after five years. OnStar Basics is included for 8 years from the in-service date, covering core connected-safety services without an immediate subscription decision.

Warranty Coverage

Coverage	Term
Bumper-to-bumper	3 years / 36,000 miles
Powertrain	5 years / 60,000 miles
Roadside assistance	5 years / 60,000 miles
Corrosion (cosmetic)	3 years / 36,000 miles
Rust-through / perforation	6 years / 100,000 miles

What These 2027 Tahoe Numbers Mean in Practice

Measurement	What It Means
93.6 in wide with mirrors	Clears a standard single garage bay; measure a narrower older bay first
211.3 in long	Fits most compact parking spaces; check depth on tight downtown Tulsa spots
Up to 10.0 in ground clearance (air ride)	Clears a rutted gravel road or a steep driveway apron
8,400 lb max tow	Covers a mid-size travel trailer or a boat bound for Keystone Lake, on the specific 5.3L/RWD/Max Trailering build only
77.5 cu ft behind 2nd row	Enough for a bulk warehouse-club run or flat-pack furniture without folding every seat
7,600 lb GVWR vs. 5,705 lb curb weight	1,895 lb of combined passenger, cargo and tongue-weight capacity before hitting the rating
24.0-gallon tank, up to 624 mi diesel range	One fill-up covers a round trip well beyond the Tulsa metro on the Duramax

None of these thresholds are a hard ceiling for every buyer; they are the numbers worth checking against a specific driveway, garage or trailer before assuming a Tahoe will or will not fit. A quick call to our sales team with the exact measurement in hand is faster than guessing from a spec sheet alone.

2027 Tahoe Specifications FAQs

How long is the 2027 Chevrolet Tahoe?

211.3 inches overall, with a 120.9-inch wheelbase.

How wide is the 2027 Tahoe with mirrors?

93.6 inches with the mirrors extended; 81.0 inches without them.

How much does a 2027 Tahoe weigh?

Curb weight is 5,705 pounds in the 5.3L configuration, with a gross vehicle weight rating of 7,600 pounds.

What is the ground clearance of a 2027 Tahoe?

8.0 inches standard, rising to as much as 10.0 inches with the available Four-Corner Air Ride Adaptive Suspension.

How much horsepower does the 2027 Tahoe have?

355 hp on the base 5.3L V8, 420 hp on the available 6.2L V8, 433 hp on the new RST Performance Edition's tuned 6.2L, and 305 hp on the available Duramax diesel. Torque tells a different story: the Duramax's 495 lb-ft beats every gas engine in the lineup, which is why it pulls a loaded trailer with less throttle effort despite its lower peak horsepower number.

What is the fuel economy of the 2027 Tahoe?

The Duramax diesel leads at up to 24 mpg combined (RWD) and 22 mpg combined (4WD); the two gas V8s run 16 to 17 mpg combined depending on drivetrain. These are 2026-certified figures for unchanged 2027 powertrains, cited from fueleconomy.gov, since Chevrolet has not yet published a separate 2027 certification for the Tahoe.

What is the Tahoe's fuel tank size?

24.0 gallons across every engine and trim.

What is the 2027 Tahoe's warranty?

3 years/36,000 miles bumper-to-bumper, 5 years/60,000 miles powertrain, and 6 years/100,000 miles against rust-through, with roadside assistance also covered for 5 years/60,000 miles. Scheduled maintenance intervals and the GM Oil Life System are covered in full on the maintenance page.

Is the 2027 Tahoe the same size as the 2026 model?

Yes. Body, glass and sheet metal carry over unchanged for 2027, so every exterior and interior dimension on this page applies equally to a 2026 Tahoe of the same generation.

How much cargo capacity difference is there between Tahoe trims?

None by trim — maximum cargo volume, behind-second-row and behind-third-row figures are the same across the lineup. What changes by trim is seating configuration, not cargo capacity.
