The Toyota 4Runner III, specifically the facelifted version produced from 1999 to 2000, represented a significant evolution of Toyota’s popular mid-size SUV. This generation, known internally as the 180 series, continued the 4Runner’s reputation for ruggedness and reliability while incorporating more refined features. The 2.7-liter 16V (150 hp) Automatic variant occupied the entry-level position in the 4Runner lineup during these years, offering a more affordable and fuel-conscious option compared to the more powerful V6 models. It was primarily marketed towards buyers seeking a capable SUV for daily driving and light off-road use, prioritizing practicality and value over outright performance.

INTRODUCTION
The 1999-2000 Toyota 4Runner III facelift brought subtle but important updates to the already successful third-generation model. The 2.7-liter engine paired with an automatic transmission was a key component of the lineup, designed to appeal to a broader customer base. This configuration offered a balance between affordability, fuel efficiency, and the 4Runner’s inherent off-road capability. Positioned as the base model, it provided a stepping stone into the 4Runner family, allowing buyers to experience the vehicle’s core attributes without the higher price tag of the V6 options. The 4Runner continued to be a mainstay in the North American SUV market, known for its body-on-frame construction and durable mechanicals.
Powertrain & Engine Architecture
The heart of this 4Runner variant is the 3RZ-FE 2.7-liter inline-four cylinder engine. This engine is a naturally aspirated, gasoline-powered unit featuring a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The 3RZ-FE utilizes a multi-port fuel injection system, delivering fuel directly to each intake port for improved combustion efficiency. The engine’s 9.5:1 compression ratio contributes to its respectable power output for its displacement. The automatic transmission paired with this engine is a four-speed unit, designed for smooth and reliable operation. While not offering the quickest acceleration, this transmission provided convenient shifting and adequate performance for everyday driving. The transmission was chosen for its durability and ease of use, aligning with the 4Runner’s overall focus on practicality.
Driving Characteristics
The 150 horsepower and 240 Nm (177 lb-ft) of torque produced by the 2.7-liter engine and automatic transmission combination resulted in a driving experience focused on usability rather than outright speed. Acceleration was adequate for merging onto highways and navigating city streets, but it lacked the punch of the V6 models. The four-speed automatic transmission, while smooth, had relatively wide gear ratios, which could sometimes result in the engine feeling strained during uphill climbs or when carrying a full load. Compared to the five-speed manual transmission available on some 4Runner models, the automatic offered less driver engagement but greater convenience. 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 in challenging conditions.
Equipment & Trim Levels
The 2.7-liter Automatic 4Runner typically came standard with features such as air conditioning, power windows and locks, and an AM/FM stereo. Interior upholstery was typically cloth, with a durable and practical design. Optional extras included features like a CD player, upgraded sound system, and alloy wheels. Higher trim levels, such as the SR5, offered additional features like cruise control, a tilt steering wheel, and upgraded interior trim. The base model prioritized essential features, keeping the price point accessible to a wider range of buyers. The dashboard layout was functional and straightforward, emphasizing ease of use and durability.
Chassis & Braking
The 4Runner III utilized a robust body-on-frame construction, providing a solid and durable platform. The front suspension featured a double wishbone design, while the rear suspension employed an independent multi-link setup, offering a comfortable ride and good handling characteristics. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. Anti-lock braking system (ABS) was standard, enhancing safety and control during emergency braking situations. The chassis was designed to withstand both on-road and off-road use, providing a stable and capable platform for various driving conditions. Stabilizer bars were included to reduce body roll during cornering.
Market Reception & Comparison
Critics generally viewed the 2.7-liter 4Runner as a sensible and practical choice for buyers who didn’t require the extra power of the V6 models. Fuel economy was a key selling point, as the four-cylinder engine offered better gas mileage than its larger counterparts. However, some reviewers noted the engine’s lack of power, particularly when fully loaded or towing a trailer. Compared to the 3.4-liter V6 4Runner, the 2.7-liter model offered a more affordable entry point but sacrificed performance. The 2.7-liter engine was also generally considered more reliable and less prone to costly repairs than the V6, making it an attractive option for budget-conscious buyers.
Legacy
The 3RZ-FE engine, found in this 4Runner variant, has earned a reputation for exceptional reliability and longevity. Many examples of this engine are still running strong today, even with high mileage. The 4Runner III, in general, is highly regarded for its durability and off-road capability, making it a popular choice in the used car market. The 2.7-liter Automatic model, while not the most sought-after trim, remains a viable option for buyers seeking a dependable and affordable SUV. Its simplicity and robust construction contribute to its continued appeal, and parts availability remains good, making maintenance relatively straightforward. The 4Runner’s enduring popularity is a testament to Toyota’s commitment to building vehicles that stand the test of time.
