Powertrain & Engine Architecture
The heart of the 4Runner 2.7 4×4 was the 3RZ-FE inline-four cylinder engine. This 2.7-liter powerplant featured a cast iron block and an aluminum cylinder head, incorporating dual overhead camshafts (DOHC) and four valves per cylinder. The 3RZ-FE utilized a multi-port fuel injection system, delivering fuel directly to each intake port for improved efficiency and responsiveness. The engine produced 150 horsepower at 4800 rpm and 240 Nm (177 lb-ft) of torque at 4000 rpm. This engine was known for its durability and relatively simple design, making it easier to maintain. The 5-speed manual transmission was the only transmission option available with this engine configuration. It was chosen for its reliability and suitability for both on- and off-road driving.
Driving Characteristics
The 2.7-liter 4Runner offered a noticeably different driving experience compared to its V6 siblings. While the V6 models prioritized acceleration and towing capacity, the 2.7 focused on fuel economy and a more relaxed driving style. Acceleration was adequate for everyday driving, but it lacked the punch of the larger engines, especially when fully loaded or tackling steep inclines. The manual transmission provided precise control, but required more driver involvement than the automatic transmissions offered with the V6 options. The gear ratios were tuned for a balance of fuel efficiency and usability, with a relatively tall fifth gear for highway cruising. Off-road, the 4Runner 2.7 4×4 proved capable, benefiting from its four-wheel drive system and robust suspension, though it required more careful throttle control and gear selection than the more powerful versions.
Equipment & Trim Levels
The 2.7 4×4 trim level typically came standard with features such as air conditioning, power steering, and an AM/FM radio. Interior upholstery was generally cloth, with a durable and practical design. Optional extras included power windows and locks, a cassette player (later upgraded to a CD player), and alloy wheels. The dashboard layout was functional and straightforward, prioritizing ease of use over luxury. The 4Runner’s interior was designed to withstand the rigors of outdoor use, with durable materials and easy-to-clean surfaces.
Chassis & Braking
The 4Runner III utilized a body-on-frame construction, providing a robust and durable platform for off-road driving. The front suspension featured a double wishbone design, while the rear suspension employed an independent multi-link setup. This combination offered a good balance of ride comfort and off-road capability. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. An Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The steering system was a rack-and-pinion setup with hydraulic power assistance, providing precise and responsive steering feel.
Market Reception & Comparison
The 4Runner 2.7 4×4 was generally well-received by critics as a practical and affordable SUV. It was praised for its reliability, fuel efficiency, and off-road capability. However, some reviewers noted its lack of power compared to the V6 models. Compared to the 3.4-liter V6 4Runner, the 2.7 offered significantly better fuel economy but considerably less performance. The 2.7 was also a more attractive option for buyers who didn’t require the towing capacity of the V6. In terms of reliability, the 3RZ-FE engine proved to be exceptionally durable, with many examples exceeding 200,000 miles with proper maintenance.
Legacy
The Toyota 4Runner 2.7 4×4 has developed a strong following among enthusiasts and used car buyers. Its reputation for reliability and durability has made it a popular choice for those seeking a long-lasting and capable SUV. The 3RZ-FE engine is known for its longevity and relatively low maintenance costs. Today, well-maintained examples of the 4Runner 2.7 4×4 can still be found on the used car market, offering a compelling value proposition for buyers seeking a rugged and reliable SUV. While not as sought after as the V6 models, the 2.7 remains a capable and dependable vehicle, representing a solid entry point into the 4Runner lineage.
