What cylinder is the 2000 Toyota 4Runner SR5?
The 2000 Toyota 4Runner SR5 uses a six-cylinder engine—the 3.4-liter V6 (5VZ-FE) that powers the SUV.
Engine configuration and specifications
Here are the core specifications that define the engine in the 2000 SR5. The model relies on a V6 configuration with Toyota's 5VZ-FE family, delivering a balance of power and reliability for a midsize SUV of its era.
Key engine specs include:
- Engine code: 5VZ-FE
- Displacement: 3.4 liters
- Configuration: 6-cylinder V
- Valve train: DOHC, 24 valves
- Fuel system: Sequential multi-port fuel injection
These specifications reflect the US-market SR5 models of the era, offering a robust acceleration profile for a mid-size SUV while maintaining reasonable fuel economy by 2000 standards.
Performance, transmission, and drivetrain
In performance terms, the 5VZ-FE was rated around 190 horsepower and about 235 lb-ft of torque, with output tuned for on-road drivability and off-road capability. It was typically paired with a 4-speed automatic transmission in most US-spec SR5s, with some 4x4 configurations offering manual gear selection in certain markets or trim packages.
Compared to later generations, the 3.4L V6 offered ample torque for towing and off-road use, helping the 4Runner maintain solid capability in the SR5 package. The SR5 badge denoted a mid-range trim with upgraded interior and exterior features, rather than changes to the engine itself.
Fuel economy and real-world use
Actual mileage varied with drivetrain (2WD vs 4WD), transmission, and driving conditions, but typical EPA-era figures for the 4Runner V6 hovered in the mid-teens in city driving and low- to mid-20s on the highway, with 4WD versions trailing slightly behind 2WD in efficiency.
Why the cylinder count matters
Choosing a six-cylinder engine like the 5VZ-FE gave the 2000 SR5 a good balance between power, torque, and durability for a family SUV that also sees light off-road use. The V6 configuration minimizes vibrations and provides smoother acceleration when carrying passengers or cargo.
Summary
In short, the 2000 Toyota 4Runner SR5 is powered by a six-cylinder, 3.4-liter V6 engine (5VZ-FE). This setup defined the model’s performance characteristics for the era and remains a common point of reference for buyers and enthusiasts assessing the vehicle’s capabilities and reliability.
