What engine is in the iforce max Tundra?
The i-FORCE MAX in the Toyota Tundra uses a 3.4-liter twin‑turbo V6 hybrid powertrain that delivers about 437 horsepower and 583 lb-ft of torque. This setup combines a gasoline engine with electric motors to maximize both performance and efficiency.
Powertrain overview
The i-FORCE MAX pairs a 3.4-liter twin-turbo V6 gasoline engine with an integrated hybrid system. The electric motors assist the gasoline engine, boosting output and peak torque, especially at low RPMs. The hybrid configuration is paired with a 10-speed automatic transmission, and the system is designed to enhance towing capability and off-road performance without sacrificing everyday drivability.
Core specifications
Key specifications of the i-FORCE MAX powertrain are listed below for quick reference:
- Engine: 3.4-liter twin-turbo V6
- Hybrid system: gasoline engine paired with electric motors integrated into the driveline
- Horsepower: 437 hp (combined output with hybrid system)
- Torque: 583 lb-ft (combined output with hybrid system)
- Transmission: 10-speed automatic
- Drivetrain: available with 4WD (part-time or fullt-time configuration depending on trim)
Together, these elements yield strong acceleration and high torque at low engine speeds, supporting both heavy towing and confident off-road driving.
Comparisons with the standard i-FORCE
To understand how the i-FORCE MAX differs from the non-hybrid version, consider these points:
- Gasoline engine: Both use a 3.4-liter twin-turbo V6, but the standard (non-hybrid) i-FORCE produces around 389 hp and 479 lb-ft of torque.
- Hybrid boost: The i-FORCE MAX adds electric motors to lift total output to about 437 hp and 583 lb-ft of torque.
- Transmission: Both configurations use a 10-speed automatic transmission.
- Capability: The hybrid MAX variant generally offers higher towing and payload capacities due to the extra torque and electric assist.
In short, the MAX variant emphasizes higher peak outputs and stronger low-end torque through hybridization, at the cost of a higher starting price compared with the non-hybrid i-FORCE version.
Performance notes and availability
Introduced with the redesigned Tundra in 2022, the i-FORCE MAX powertrain has remained the top-tier option across the lineup, including various trims and off-road-focused models. The engine is designed to deliver robust mid-range acceleration, steady highway performance, and substantial towing capability, making it a cornerstone of the Tundra’s updated powertrain family.
Summary
In the Toyota Tundra, the i-FORCE MAX is powered by a 3.4-liter twin-turbo V6 hybrid system that produces 437 hp and 583 lb-ft of torque. The hybrid setup pairs with a 10-speed automatic transmission and 4WD capability, providing strong towing and off-road performance. The standard i-FORCE version uses the same basic V6 architecture but without the hybrid electric boost, delivering roughly 389 hp and 479 lb-ft of torque. The MAX variant represents Toyota’s top-tier powertrain option for the Tundra, combining efficiency with impressive on-road and off-road capability.
