2027 Chevrolet Tahoe MPG, Engine Specs & Towing Capacity

The 2027 Chevrolet Tahoe offers three engines: a standard 5.3L EcoTec3 V8, an available 6.2L EcoTec3 V8, and an available Duramax 3.0L Turbo-Diesel inline-six. Each one targets a different priority — everyday capability, outright power, or long-haul efficiency — and each pairs with the same 10-speed automatic transmission.

What Engine Options Are Available for the 2027 Chevrolet Tahoe?

The 2027 Tahoe’s three powertrains produce 355 hp, 420 hp, and 305 hp respectively, with the diesel delivering the highest torque figure in the lineup at 495 lb-ft. Every engine pairs exclusively with an electronically controlled 10-speed automatic transmission and a Traction Select System that includes Tow/Haul mode.

5.3L EcoTec3 V8 — The Standard Engine

The 5.3L EcoTec3 V8 is standard on every trim except High Country, producing 355 hp and 383 lb-ft of torque. It uses Dynamic Fuel Management, which deactivates cylinders under light load to balance daily power demands against fuel efficiency. For drivers who want traditional naturally aspirated V8 response, it handles school runs, family road trips, and light towing without fuss — and it is the engine behind the Tahoe’s highest tow rating.

6.2L EcoTec3 V8 — The Power Upgrade

The 6.2L EcoTec3 V8 is standard on High Country and available on RST, Z71, and Premier. At 420 hp and 460 lb-ft, it gives the full-size SUV confident highway merging and strong passing response with a full cabin and cargo aboard. Independent testing of the 6.2L has produced 0–60 mph times in the 5.8 to 6.3 second range.

RST Performance Edition — New for 2027

The RST Performance Edition is the newest addition to the 2027 Tahoe lineup and the most powerful configuration Chevrolet offers in this SUV. It takes the 6.2L V8 and adds Chevrolet Performance induction and exhaust components, lifting output to 433 hp and 467 lb-ft of torque. Brembo heavy-duty front brakes are part of the package, giving the added power matching stopping capability.

Duramax 3.0L Turbo-Diesel — The Long-Haul Choice

The Duramax 3.0L Turbo-Diesel (engine code LZ0) is available on LT, RST, Z71, Premier, and High Country. This turbocharged inline-six produces 305 hp at 3,750 rpm and 495 lb-ft of torque at just 1,500 rpm — and that low torque peak is what makes it feel effortless under load.

The Duramax Diesel: EPA-Estimated Fuel Economy, Torque, and Range

Among the 2027 Tahoe’s powertrains, the Duramax 3.0L Turbo-Diesel is the efficiency choice, with an EPA-estimated 22 mpg city / 26 mpg highway / 24 mpg combined on two-wheel-drive models.^‡ Four-wheel-drive diesel models return an EPA-estimated 20 mpg city / 24 mpg highway / 22 mpg combined^‡ while still rated to pull up to 8,000 lbs with the Max Trailering Package.^§

The standout attribute of the Duramax is where its torque arrives. All 495 lb-ft is available at just 1,500 rpm, so the engine pulls heavy loads away from a complete stop without the driver working it hard. There is no need to rev deep into the tach to launch a trailer or climb a highway grade, and the result is a quieter, more composed cabin while towing.

With a 24-gallon fuel tank, two-wheel-drive diesel models offer an available EPA-estimated maximum highway range of up to 624 miles per fill-up.^‡ For drivers covering long highway miles between Waynesboro, Chambersburg, and Hagerstown, that efficiency translates directly into fewer fuel stops. For 2027, Chevrolet also expanded availability so the Duramax can be paired with Super Cruise hands-free driver assistance technology — previously a gas-V8-only combination.^¶

§ Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

Always obey traffic laws and stay attentive to the road. See your owner’s manual for system details and limitations.

What Is the Maximum Towing Capacity of the 2027 Chevrolet Tahoe?

Properly equipped, the 2027 Chevrolet Tahoe tows up to 8,400 lbs.^§ That maximum belongs to one specific build: the 5.3L EcoTec3 V8 with rear-wheel drive and the Max Trailering Package. Without the trailering hardware, most ratings start lower — which makes equipment selection the single most important decision for buyers planning to pull a camper or a boat.

Towing Capacity by Engine and Drivetrain

The diesel is the exception worth knowing: in rear-wheel drive it carries the same 8,200-lb rating with or without the Max Trailering Package. On every other configuration, the package is what raises the number. Payload varies by build, so confirm the figure on your vehicle’s door-jamb label before hitching up.^§

What the Max Trailering Package Adds

The Max Trailering Package also brings the Advanced Trailering Package. Key integrated features include:

For families near Greencastle and Gettysburg pulling ski boats, horse trailers, or travel campers, this trailering setup is what turns a tow rating on paper into confidence on a steep grade.

How the 6.2L V8 Compares on Power and Towing

At the top of the gas lineup, the 6.2L EcoTec3 V8 brings 420 hp and a towing ceiling of 8,200 lbs with the Max Trailering Package.^§ The 5.3L actually holds a 200-lb advantage at the very top of the tow chart — 8,400 lbs against the 6.2L’s 8,200 — so the engine that tows the most is the standard one, not the optional one.

What the 6.2L buys is response rather than capacity: noticeably quicker acceleration and stronger passing power when the Tahoe is loaded with passengers and gear. The trade-offs are at the pump. The 6.2L asks for premium 91-octane fuel to reach its rated output, and in four-wheel drive it returns an EPA-estimated 14 mpg city / 18 mpg highway against the 5.3L’s 15 / 19.^‡ Buyers who want maximum pulling capacity should start with the 5.3L and the Max Trailering Package; buyers who want the strongest throttle response should start with the 6.2L.

The 2027 Chevrolet Suburban offers the same three engines if you need the longer wheelbase.

EPA-Estimated MPG by Engine and Drivetrain

EPA-estimated fuel economy for the 2027 Chevrolet Tahoe ranges from 14 mpg city / 18 mpg highway on 4WD 6.2L V8 models to 22 mpg city / 26 mpg highway on 2WD Duramax diesel models.^‡ Engine choice and drivetrain are the two variables that move the number most.

Keeping your Tahoe’s tire pressures correct, its air filter clean, and its oil fresh is what keeps real-world results tracking close to these EPA estimates over the life of the vehicle.

Common Questions About 2027 Tahoe Performance and Towing

What is included in the Chevrolet Tahoe Max Trailering Package?

The Max Trailering Package includes an extra-capacity cooling system, an integrated trailer brake controller, Hitch Guidance with Hitch View, and Blind Zone Steering Assist with Trailering. It also brings the Advanced Trailering Package, which adds the Smart Trailer Integration Indicator — the system that runs trailer light checks and monitors trailer tire pressure from the center display.^¶

Can the 2027 Chevrolet Tahoe tow a travel trailer or wake boat?

Yes. With maximum towing ranging from 7,600 lbs to 8,400 lbs depending on engine, drivetrain, and equipment, the 2027 Tahoe handles medium-to-large travel trailers, wakeboard boats, horse trailers, and utility haulers.^§ Matching the build to the trailer matters more than the headline number — the 8,400-lb rating requires the 5.3L V8, rear-wheel drive, and the Max Trailering Package.

What is the difference in driving feel between the Duramax diesel and the 6.2L V8?

The Duramax delivers its 495 lb-ft of torque at just 1,500 rpm, which produces strong, effortless pulling right off the line without heavy engine revving. The 6.2L V8 makes its 420 hp higher up, at 5,600 rpm, offering rapid acceleration and a throatier exhaust note for drivers who want performance-oriented power.

Do all 2027 Chevrolet Tahoe models come with a 10-speed automatic transmission?

Yes. Every 2027 Tahoe engine — the 5.3L V8, the 6.2L V8, and the Duramax 3.0L Turbo-Diesel — pairs with an electronically controlled 10-speed automatic transmission featuring driver-selectable Tow/Haul mode.
