When did 4Runner switch to V6?
The 4Runner first offered a V6 engine in the 1990 model year.
This marked a turning point for Toyota’s rugged SUV, shifting from an all-four-cylinder lineup toward more powerful, smoother V6 power. The move was gradual, with newer V6 options rolled out across generations to improve torque, towing, and on-road refinement while preserving the vehicle’s off-road capability.
Milestones in the V6 transition
Key moments when Toyota introduced or expanded V6 power within the 4Runner lineup:
- 1990 model year: 3.0-liter V6 option (3VZ-FE) added to the 4Runner, alongside four-cylinder engines.
- Late 1990s: Introduction of the 3.4-liter V6 (5VZ-FE) and broader adoption across trims, increasing torque and towing capability.
- 2010 model year (5th generation): Introduction of the 4.0-liter V6 (1GR-FE) for the latest generation, becoming the standard powerhouse in many trims.
These milestones illustrate a gradual evolution rather than a single abrupt change, aligning the 4Runner with Toyota’s broader V6 strategy while preserving its rugged character.
Current state: powertrains in the latest 4Runner
In the current generation, Toyota typically outfits the 4Runner with a 4.0-liter V6 that delivers strong low-end torque for off-road climbs and towing, paired with modern transmissions and drivetrain systems to maximize performance and reliability.
Why the move mattered
The transition to V6 power provided smoother operation, improved torque delivery, and better overall refinement without sacrificing off-road capability. It also aligned the 4Runner with Toyota’s broader V6 family, simplifying maintenance and parts availability across models.
Summary: The 4Runner’s V6 era began in 1990 and has evolved through successive generations, culminating in the current 4.0-liter V6 powering today’s models.
