How much horsepower does a Toyota Tundra 3.5 twin-turbo have?
The Toyota Tundra's 3.5-liter twin-turbo V6 delivers up to 437 horsepower in the hybrid i-Force MAX setup, and 389 horsepower in the standard non-hybrid version.
That difference arises from whether Toyota pairs the gas engine with an electric motor and battery in the i-Force MAX, delivering more power and peak torque. The following outlines the two main horsepower figures and what drives the difference.
Powertrain options and horsepower
Below is a concise breakdown of horsepower figures by configuration.
- Non-hybrid 3.5L twin-turbo V6: 389 horsepower, 479 lb-ft of torque.
- i-Force MAX hybrid: 437 horsepower, 583 lb-ft of torque.
Both variants use Toyota's 10-speed automatic transmission and are offered with 4x2 or 4x4 drivetrains, which affect overall performance and efficiency but not the advertised engine outputs themselves.
Context and availability
The hybrid i-Force MAX version has been available since the Tundra's 2022 redesign and is typically found on higher trim levels (such as Limited, Platinum, and TRD Pro). If you are shopping, check the window sticker or Toyota's official spec sheet for your exact model year to confirm horsepower, torque, and drivetrain options for your build.
Summary
In short, the Toyota Tundra’s 3.5-liter twin-turbo engine offers two primary horsepower figures depending on configuration: 389 hp in the standard non-hybrid setup and 437 hp in the i-Force MAX hybrid setup, with higher torque in the hybrid variant. Always verify the exact specs for your specific model year and trim, as configurations and numbers can vary by market.
