Powertrain & Engine Architecture
The heart of the RX III 350 4WD is the 2GR-FE, a 3.5-liter (3456 cc) naturally aspirated V6 engine. This engine is a member of Toyota’s GR family, known for its durability and smooth operation. The 2GR-FE utilizes a 60-degree V-angle, contributing to its balance and reduced vibrations. It features a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for increased power output. Fuel delivery is managed by a multi-port fuel injection system, providing precise fuel metering. The engine produces 277 horsepower at 6200 rpm and 255.2 lb-ft of torque at 4700 rpm. The engine is paired with a five-speed automatic transmission, which was a carryover from the previous generation. While not as modern as some of its competitors’ six or eight-speed transmissions, it was known for its reliability and smooth shifts. The transmission’s gear ratios were tuned for a balance of fuel efficiency and responsiveness, prioritizing comfortable cruising over aggressive acceleration.
Driving Characteristics
The RX III 350 4WD offered a comfortable and refined driving experience. The 277 hp engine provided adequate power for everyday driving and highway cruising, with a 0-60 mph time of around 7.6 seconds. However, it wasn’t designed for sporty performance. The five-speed automatic transmission, while smooth, could sometimes feel a bit dated, especially when compared to newer transmissions with more gears. The all-wheel-drive system provided enhanced traction in inclement weather, making it a capable vehicle in a variety of conditions. The suspension was tuned for comfort, absorbing bumps and providing a smooth ride. Compared to the RX 350 with front-wheel drive, the 4WD version offered improved stability and handling, particularly on slippery surfaces. It wasn’t as fuel efficient as the FWD model, but the added security of all-wheel drive was a worthwhile trade-off for many buyers. The steering felt light and precise, making it easy to maneuver in city traffic.
Equipment & Trim Levels
The RX III 350 4WD typically came well-equipped with standard features such as leather upholstery, power-adjustable front seats, a premium sound system, and a navigation system. Available options included a panoramic sunroof, heated and ventilated front seats, rear-seat entertainment, and advanced safety features like adaptive cruise control and lane departure warning. Trim levels varied slightly depending on the year, but generally included base models and more luxurious versions with additional features. The interior design emphasized luxury and comfort, with high-quality materials and a user-friendly layout. The dashboard featured a prominent center console with a large display screen for the navigation and infotainment systems. Wood trim accents were common, adding to the upscale ambiance.
Chassis & Braking
The RX III 350 4WD utilized a robust chassis with a fully independent suspension system. The front suspension featured MacPherson struts, while the rear suspension employed a double-wishbone setup. This configuration provided a comfortable ride and good handling characteristics. Braking duties were handled by ventilated discs at the front and solid discs at the rear, equipped with an anti-lock braking system (ABS) as standard. The hydraulic power steering provided precise and responsive steering feel. The vehicle’s relatively heavy curb weight (around 4519 lbs) contributed to its stability but also impacted its agility. Stabilizer bars were fitted to both the front and rear suspensions to reduce body roll during cornering.
Market Reception & Comparison
The Lexus RX III 350 4WD was generally well-received by critics and consumers alike. It was praised for its luxurious interior, comfortable ride, and reliable powertrain. However, some critics noted that the five-speed automatic transmission felt outdated compared to competitors. Compared to other luxury crossovers in its class, such as the Acura MDX and BMW X5, the RX 350 4WD offered a more comfortable and refined ride, but it wasn’t as sporty to drive. Fuel economy was average for its class, with EPA estimates around 18 mpg city and 24 mpg highway. The RX 350 4WD’s reputation for reliability and low maintenance costs made it a popular choice among buyers seeking a long-term ownership experience. The Acura MDX offered a slightly more engaging driving experience, while the BMW X5 prioritized performance and handling.
Legacy
The Lexus RX III 350 4WD has proven to be a durable and reliable vehicle, with many examples still on the road today. The 2GR-FE engine is known for its longevity and relatively low maintenance requirements. Common issues are typically minor, such as oil leaks or sensor failures. On the used car market, the RX III 350 4WD holds its value well, thanks to its reputation for quality and reliability. It remains a popular choice for buyers seeking a comfortable, luxurious, and dependable crossover SUV. The RX III generation solidified the RX’s position as a leader in the luxury crossover segment, setting the stage for future generations of the model. Its blend of comfort, reliability, and all-weather capability continues to appeal to a wide range of buyers.
