The Lexus RX 350 (specifically the second generation, internally designated RX II, produced from 2006 to 2009) represents Lexus’s continued success in the luxury crossover SUV market. Building upon the groundbreaking first-generation RX, the RX II refined the formula with increased size, improved interior appointments, and a more powerful engine option. The 350 model, equipped with the 2GR-FE 3.5-liter V6 engine and a five-speed automatic transmission, was a mainstay of the RX II lineup, positioned as the volume seller offering a balance of performance, luxury, and fuel efficiency. This variant was particularly popular in North America, where the demand for larger, comfortable SUVs was high.

INTRODUCTION
The RX 350, as part of the second-generation RX (2006-2009), represented a significant step forward for Lexus in terms of size and refinement. The RX II was built on an evolution of the K-platform, known internally as the 1HX0, and aimed to provide a more luxurious and spacious experience than its predecessor. The 350 variant, with its 3.5-liter V6, became the most popular choice for buyers seeking a comfortable and capable luxury SUV. It slotted in above the base RX 300 (which continued in some markets) and below the hybrid RX 400h, offering a compelling blend of performance and fuel economy for the segment.
Powertrain & Engine Architecture
At the heart of the RX 350 lies the 2GR-FE 3.5-liter dual overhead cam (DOHC) V6 engine. This engine is a member of Toyota’s GR family, known for its reliability and smooth power delivery. The 2GR-FE utilizes multi-port fuel injection and a variable valve timing system (VVT-i) to optimize performance and efficiency. Producing 276 horsepower at 6200 rpm and 252 lb-ft of torque at 4700 rpm, the engine provided ample power for everyday driving and confident highway passing. The engine’s transverse mounting and all-wheel-drive configuration contribute to its balanced handling characteristics. Paired with the 2GR-FE is a five-speed automatic transmission. While not as technologically advanced as some of its competitors’ six or seven-speed automatics, the Lexus transmission was known for its smooth shifts and durability. The transmission was tuned for comfort rather than outright sportiness, prioritizing a relaxed driving experience.
Driving Characteristics
The RX 350 with the five-speed automatic delivers a comfortable and refined driving experience. Acceleration from 0-60 mph takes approximately 7.4 to 7.8 seconds, which is competitive for its class. The automatic transmission provides smooth, almost imperceptible shifts during normal driving. However, it can sometimes feel hesitant during quick acceleration or when downshifting for passing maneuvers. Compared to the RX 300, the 350 offers noticeably more power and responsiveness. The RX 400h, with its hybrid powertrain, provides even quicker acceleration but at the expense of fuel economy in certain driving conditions. The all-wheel-drive system provides excellent traction in various weather conditions, enhancing stability and confidence. The suspension is tuned for comfort, absorbing bumps and road imperfections effectively, but this can result in some body roll during cornering.
Equipment & Trim Levels
The RX 350 came well-equipped as standard, reflecting its luxury positioning. Standard features typically included leather upholstery, power-adjustable front seats, a premium audio system, automatic climate control, and alloy wheels. Optional extras included a navigation system, a rear-seat entertainment system, power-folding mirrors, and a moonroof. Trim levels varied slightly depending on the market, but generally, the RX 350 offered a range of options to customize the vehicle to individual preferences. Interior materials were of high quality, and the cabin was designed to provide a quiet and comfortable environment for both driver and passengers.
Chassis & Braking
The RX 350 utilizes a coil spring independent suspension system at all four corners. The front suspension features MacPherson struts, while the rear employs a double-wishbone setup. This configuration provides a comfortable ride and predictable handling. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The anti-lock braking system (ABS) is standard, enhancing safety and control during emergency braking situations. The steering is rack-and-pinion with hydraulic power assist, providing a responsive and precise feel. The RX 350’s chassis is designed to prioritize comfort and stability over sporty handling, making it well-suited for long-distance cruising and everyday driving.
Market Reception & Comparison
The Lexus RX 350 was widely praised by automotive critics for its comfortable ride, spacious interior, and refined powertrain. It consistently ranked highly in reliability surveys, further solidifying its reputation as a dependable luxury SUV. Compared to competitors like the Acura MDX and BMW X5, the RX 350 offered a more comfortable ride and a simpler, more user-friendly interface. However, some critics noted that its handling was not as sporty as some of its rivals. Fuel economy was generally considered average for the segment, with combined ratings around 21 mpg. The RX 400h offered better fuel economy, but at a higher initial cost.
Legacy
The second-generation Lexus RX 350, particularly the 3.5-liter V6 model, has proven to be a remarkably reliable vehicle. The 2GR-FE engine is known for its longevity and minimal maintenance requirements. Today, well-maintained RX 350s from this era can still provide years of dependable service. The used car market values these vehicles for their reputation for reliability, comfortable ride, and luxurious features. While not the most exciting SUV to drive, the RX 350 remains a popular choice for buyers seeking a practical, comfortable, and dependable luxury crossover.
