2026 Toyota Tundra i-FORCE vs. i-FORCE MAX: Which Should You Choose?

Published September 24, 2026

Freeman Toyota compares the 2026 Toyota Tundra i-FORCE and i-FORCE MAX powertrains, including horsepower, torque, EPA-estimated fuel economy, towing considerations, and trim availability.

The standard-output i-FORCE produces 389 horsepower and 479 lb-ft of torque, while i-FORCE MAX produces 437 net combined horsepower and 583 lb-ft of torque. The Tundra SR uses a lower-output i-FORCE calibration, so output should be confirmed for the specific grade. Choosing between the two powertrains involves more than comparing output. The specific trim, drivetrain, fuel-economy estimates, towing and payload requirements, equipment, and price can all matter.

Towing capacity is configuration-specific. More horsepower and torque do not automatically result in a higher tow rating, so shoppers should verify the published rating for the specific Tundra configuration they are considering.
