Two powerplant configurations will be offered: a new, twin-turbo 3.5-liter V6 that makes up to 389 horsepower and 479 lb-ft. of torque; and that engine paired with a bellhousing electric motor system called the i-FORCE MAX, to give a combined output of 437 horsepower and 583 lb.-ft. of torque. Both configurations will be mated to a new 10-speed automatic transmission.
The new multi-link rear suspension replaces the previous truck's leaf springs with coil springs. This helps raise the Tundra's towing capacity to 12,000 pounds, 17.6% over the previous generation. The maximum payload is 1,940 pounds, an improvement of more than 11% from the previous generation.
