What Tahoe has the most horsepower?
The Chevrolet Tahoe’s most powerful variant is the one equipped with the 6.2-liter V8 engine, producing 420 horsepower (with about 460 lb-ft of torque). Other available powertrains—the 5.3-liter V8 and the 3.0-liter Duramax diesel—offer lower horsepower figures.
Powertrain overview
Chevrolet offers three primary engines in the Tahoe lineup for recent model years: a 5.3L V8, a 6.2L V8, and a 3.0L Duramax turbo-diesel. Each engine is paired with a 10-speed automatic transmission and shapes performance, towing capability, and efficiency across trims.
Engine options and horsepower
Here are the horsepower figures for the current Tahoe engine lineup to compare power levels across options.
- 5.3L V8: 355 horsepower
- 6.2L V8: 420 horsepower
- 3.0L Duramax turbo-diesel: 277 horsepower
In short, if maximizing horsepower is the goal, the Tahoe with the 6.2-liter V8 is the peak option, followed by the 5.3-liter V8 and then the diesel when considering horsepower alone.
Performance implications
The numbers tell part of the story: the 6.2L V8 not only delivers the highest horsepower but also about 460 lb-ft of torque, which translates to stronger acceleration and robust towing capability. The Duramax diesel emphasizes high-torque efficiency and long-range economy, while the 5.3L V8 offers a balanced blend of power and everyday usability.
Summary
For the maximum horsepower in the current Tahoe lineup, choose the model equipped with the 6.2L V8 engine, rated at 420 horsepower and 460 lb-ft of torque. This engine is available on higher trims, making it the most powerful option among the Tahoe’s gasoline offerings. The 5.3L V8 and the 3.0L Duramax diesel provide appealing alternatives depending on priorities like efficiency or towing needs.

Key LTZ upgrades include perforated leather seats (heated and ventilated front seats), an upgraded Bose audio system, Magnetic Ride Control, and advanced safety features like Lane Change Alert with Side Blind Zone Alert.
