The Lexus RX 350L V6, produced from 2016 to 2019, represents a significant expansion of the RX line, adding a third-row seating option to the already popular luxury crossover. Positioned as a premium offering within the fourth generation (RX IV) of the RX series, the 350L aimed to cater to families requiring additional passenger capacity without sacrificing the Lexus hallmarks of comfort, refinement, and reliability. This variant utilized the well-established 2GR-FKS engine paired with an eight-speed automatic transmission and Lexus’s sophisticated all-wheel-drive system. The “L” designation signifies the extended wheelbase and body length necessary to accommodate the third row.

Powertrain & Engine Architecture
The heart of the RX 350L is the 2GR-FKS 3.5-liter V6 engine. This engine is a naturally aspirated powerplant featuring Toyota’s D-4S fuel injection system, combining direct and port injection for optimized efficiency and power delivery. The 2GR-FKS also incorporates Variable Valve Timing-intelligent Wide (VVT-iW) technology on the intake valves, further enhancing performance and fuel economy. The engine produces 290 horsepower at 6,300 rpm and 267 lb-ft of torque at 4,700 rpm. This power is channeled through a smooth-shifting eight-speed automatic transmission, a significant upgrade from the six-speed unit found in earlier RX models. The transmission is designed for both responsive acceleration and relaxed highway cruising. Lexus’s all-wheel-drive system, typically a reactive system, distributes power to the front wheels under normal conditions and engages the rear wheels when traction is lost.
Driving Characteristics
The RX 350L with the 3.5L V6 and automatic transmission delivers a comfortable and refined driving experience. While not a performance-oriented vehicle, the powertrain provides adequate acceleration for everyday driving situations. The eight-speed automatic transmission helps to keep the engine in its optimal power band, resulting in smooth and predictable power delivery. Compared to the standard RX 350, the 350L’s added weight due to the third row and extended body slightly diminishes acceleration. The gear ratios are tuned for fuel efficiency and comfort rather than outright speed. The all-wheel-drive system provides enhanced stability and traction in inclement weather conditions.
Equipment & Trim Levels
The RX 350L was generally well-equipped, even in its base trim. Standard features typically included Lexus Safety System+, which encompasses pre-collision system with pedestrian detection, lane departure alert with intelligent steering assist, and dynamic radar cruise control. Interior amenities included leather upholstery, power-adjustable front seats, a Lexus Display Audio system with a 8-inch screen, and a rearview camera. Higher trim levels, such as the Luxury and F Sport, added features like wood trim, upgraded audio systems (Mark Levinson), heated and ventilated front seats, and a panoramic sunroof. The third-row seats were relatively compact and best suited for children or smaller adults.
Chassis & Braking
The RX 350L utilizes a MacPherson strut front suspension and a double-wishbone rear suspension, tuned for a comfortable ride. The suspension is designed to absorb bumps and irregularities in the road surface, providing a smooth and isolated driving experience. The RX 350L features ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic brake-force distribution (EBD) are standard safety features. The steering is electrically assisted, providing light and precise steering feel.
Market Reception & Comparison
The RX 350L was generally well-received by critics and consumers alike. It filled a niche in the luxury crossover market for those needing a third row without opting for a larger, more cumbersome SUV. Compared to the standard RX 350, the 350L offered the added versatility of a third row, but at the expense of some cargo space and slightly reduced fuel economy. The 350L’s fuel economy of around 22 mpg combined was competitive with other luxury crossovers in its class. Reliability was a strong point, consistent with Lexus’s reputation.
Legacy
The 2GR-FKS engine paired with the eight-speed automatic transmission has proven to be a reliable and durable powertrain. The RX 350L continues to be a popular choice in the used car market, prized for its comfort, reliability, and spacious interior. While not the sportiest SUV, it offers a compelling blend of luxury, practicality, and dependability. Common maintenance items include routine oil changes, fluid flushes, and brake service. The Lexus RX 350L remains a strong contender for buyers seeking a well-rounded and dependable luxury crossover.
