What engine does the 2026 Chevrolet Tahoe have? V8 options and mpg for Estero drivers

The 2026 Chevrolet Tahoe comes with two V8 engines, a 5.3L EcoTec3 and a 6.2L EcoTec3, plus a 3.0L Duramax turbo-diesel. Chevrolet’s published figures show which trim carries each engine and what mpg each one returns, and Group 1 Chevrolet Estero Bay sells the Tahoe to Estero drivers.

Every Estero buyer chooses among those three engines, and the choice comes down to power, fuel economy and towing. Chevrolet’s own specifications answer each of those questions.

Does the 2026 Chevrolet Tahoe come with a V8 at Group 1 Chevrolet Estero Bay?

Yes. The 2026 Tahoe is offered with a 5.3L EcoTec3 V8 and a 6.2L EcoTec3 V8, and Group 1 Chevrolet Estero Bay sells the Tahoe new at 10640 Chevrolet Way in Estero. Chevrolet’s own engine list for the 2026 model year names both V8s and the diesel. We sell new Chevrolet, including the Tahoe, Suburban and Silverado 1500, and we also offer used and certified pre-owned vehicles.

What power does the Tahoe’s 5.3L V8 make in the 2026 model?

The 5.3L EcoTec3 V8 makes 355 horsepower and 383 lb-ft of torque in the 2026 Tahoe. It is standard on every Tahoe except the High Country. Chevrolet’s EPA record pairs it with an automatic 10-speed transmission.

What does the Tahoe’s 6.2L V8 add over the 5.3L?

The 6.2L EcoTec3 V8 makes 420 horsepower and 460 lb-ft of torque. It is standard on the High Country and available on the RST, Z71 and Premier. Buyers who want the most power from a gasoline Tahoe will look here first.

What mpg does each 2026 Chevrolet Tahoe engine get for Estero drivers?

These are the EPA-certified figures for the 2026 Tahoe. The diesel returns the best mpg in both drive types.

The combined number is not a simple average. The EPA weights city driving at 55% and highway driving at 45% (U.S. Environmental Protection Agency, 2026). Florida’s urban Interstates are busy at rush hour, with TRIP reporting in June 2026 that 79 percent are congested during peak hours (TRIP, 2026). That makes the city figure a useful number for a daily Estero commute.

How does the Tahoe’s 3.0L Duramax diesel compare with the V8s on mpg?

The Duramax diesel gets the highest mpg of the three engines in every drive type. In 2WD it is rated 26 mpg highway and 24 combined, against 20 and 17 for either V8. In 4WD it is rated 22 mpg combined, against 17 for the 5.3L and 16 for the 6.2L.

The diesel makes the most torque of the three, at 495 lb-ft, while the 6.2L leads on horsepower at 420. The diesel is available on the LT, RST, Z71, Premier and High Country.

How much can the 2026 Chevrolet Tahoe tow with each engine?

Chevrolet’s published maximum is 8,400 lbs for a 2WD Tahoe with the 5.3L V8 and the Max Trailering Package. The 4WD version with the same engine and package is rated at 8,200 lbs. Those ratings are what a buyer should plan a boat or trailer around.

I arrived after having a negative experience at a Naples Chevy dealership and Shaun, Chris and financing provided a completely different experience. I highly recommend starting your car buying here because I guarantee you won’t shop elsewhere. They made what I felt like an impossible transaction so effortless and I couldn’t be more grateful. Very efficient and amazing. Again thank you all and if I purchase a new vehicle in the future I will certainly return! -Hollie”
