The Toyota 4Runner IV, specifically the facelifted version produced from 2005 to 2009, represented a significant evolution of Toyota’s popular mid-size SUV. The 4.0i V6 24V variant, equipped with a five-speed automatic transmission, occupied a prominent position within the 4Runner lineup, offering a balance of power, comfort, and capability. This iteration, built on the 120-series platform, catered to buyers seeking a robust SUV with a more refined driving experience than the base four-cylinder models. It was primarily marketed in North America, Australia, and parts of the Middle East, where demand for larger, body-on-frame SUVs remained strong.

Powertrain & Engine Architecture
The heart of the 4Runner 4.0i was the 1GR-FE 4.0-liter V6 engine. This engine, part of Toyota’s GR family, featured a cast-iron block and aluminum cylinder heads. It employed a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its respectable power output. The 1GR-FE utilized a multi-port fuel injection system, delivering fuel directly to each intake port. The engine’s 10:1 compression ratio was a compromise between performance and fuel efficiency. Paired with this engine was a five-speed automatic transmission, known for its smooth shifting and reliability. This transmission was designed to handle the engine’s torque and provide adequate acceleration for both on-road and off-road driving. The transmission featured overdrive for improved highway fuel economy.
Driving Characteristics
The 4.0i V6 with the automatic transmission delivered a comfortable and capable driving experience. While not a performance-oriented SUV, the engine provided sufficient power for everyday driving and towing. Acceleration from 0 to 60 mph typically took around 7.5-8.5 seconds. The automatic transmission’s gear ratios were tuned for a balance of acceleration and fuel economy. Compared to the five-speed manual transmission available on some 4Runner models, the automatic offered smoother shifts but slightly reduced responsiveness. The automatic also lacked the engine braking benefits of a manual transmission, particularly noticeable during downhill driving. The rear-wheel-drive configuration, standard on this trim, provided a more traditional SUV feel, while four-wheel drive was available as an option for enhanced traction.
Equipment & Trim Levels
The 4Runner 4.0i typically came well-equipped, even in its base form. Standard features included air conditioning, power windows and locks, a CD player, and cloth upholstery. Higher trim levels, such as the Limited, added features like leather upholstery, a sunroof, upgraded audio systems, and automatic climate control. Optional extras included a navigation system, rear-seat entertainment, and running boards. The interior design was functional and durable, prioritizing practicality over luxury. The 4Runner’s spacious interior comfortably accommodated up to seven passengers, depending on the seating configuration.
Chassis & Braking
The 4Runner IV utilized a traditional body-on-frame construction, providing a robust and durable platform. The front suspension featured a double wishbone design, while the rear suspension employed an independent multi-link setup. This suspension configuration offered a good balance of ride comfort and off-road capability. Braking duties were handled by ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The 4Runner’s relatively high ground clearance of 8.7 inches allowed it to tackle moderate off-road obstacles with ease.
Market Reception & Comparison
The 4Runner 4.0i V6 Automatic was generally well-received by automotive critics. It was praised for its reliability, spacious interior, and off-road capability. However, some critics noted that its fuel economy was relatively poor compared to newer crossover SUVs. Compared to the base 2.7-liter four-cylinder 4Runner, the 4.0i offered significantly more power and a more refined driving experience, but at a higher price point. Against competitors like the Jeep Grand Cherokee and Ford Explorer, the 4Runner stood out for its rugged construction and Toyota’s reputation for reliability.
Legacy
The 1GR-FE engine, in particular, has proven to be exceptionally durable and reliable. Many 4Runner 4.0i models have surpassed 200,000 miles with proper maintenance. The five-speed automatic transmission has also demonstrated good longevity. On the used car market, these 4Runners hold their value well, due to their reputation for reliability and capability. They remain a popular choice for buyers seeking a dependable and versatile SUV, particularly those who need a vehicle capable of handling both on-road and off-road adventures. The 2005-2009 facelifted models are often preferred for their updated styling and improved features compared to earlier iterations of the fourth-generation 4Runner.
