How much horsepower does a 5.7 iForce have?
The 5.7 i-Force V8 delivers 381 horsepower.
In context, this 5.7-liter, naturally aspirated V8 has powered Toyota’s full-size pickups and SUVs for years, notably the Tundra and Sequoia. It’s prized for strong low- and mid-range torque and proven durability, even as Toyota expanded its powertrain lineup with newer hybrid options.
Engine specifications at a glance
Below are the core figures fans and buyers typically reference when evaluating the 5.7 i-Force V8. This list provides a concise snapshot of output and basic design characteristics.
- Horsepower: 381 hp at 5,600 rpm
- Torque: 401 lb-ft at 3,600 rpm
- Displacement: 5.7 liters
- Configuration: V8
- Common applications: Toyota Tundra and Sequoia (generation-to-generation use varies)
These specifications reflect the engine's typical production setup and output in its traditional gasoline-powered form.
Context and how it compares to newer powertrains
As Toyota added the i-Force MAX family, the company introduced a modern 3.5-liter hybrid V6 that sits alongside the 5.7-liter V8 in the lineup. For quick comparison, the newer powertrain achieves:
- Horsepower: 437 hp
- Torque: 583 lb-ft
- Drivetrain: Hybrid twin-turbo V6
The 5.7 i-Force V8 and the i-Force MAX represent two paths within Toyota’s approach to power: a durable, high-torque V8 for traditional gasoline-powered applications, and a newer hybrid setup that emphasizes higher peak output and improved efficiency.
Summary
The 5.7 i-Force V8 is officially rated at 381 horsepower with 401 lb-ft of torque, a configuration that has served Toyota’s Tundra and Sequoia models with durable, steady performance. By contrast, the latest i-Force MAX hybrid delivers 437 horsepower and 583 lb-ft of torque, illustrating Toyota’s broader strategy to offer both proven V8 powertrains and modern hybrid performance.
