2017-2020 Lexus IS III (XE30 facelift ) 300 V6 (260 Hp) AWD ECT

The Lexus IS 300, specifically the AWD variant equipped with the 260 horsepower V6 and 6-speed automatic transmission (ECT), represents a significant iteration of the third-generation (XE30) IS model line. Introduced with the 2017 facelift, this configuration was produced through the 2020 model year. Positioned as a mid-range offering within the IS family, it bridged the gap between the base 200t model and the high-performance IS 350. The XE30 generation, built on the Lexus New Global Architecture (AN21), aimed to refine the IS’s driving dynamics and interior quality while maintaining its reputation for reliability and luxury.

Technical Specifications

INTRODUCTION

The Lexus IS 300 AWD, introduced as part of the XE30 facelift in 2017, offered a compelling blend of performance, luxury, and all-weather capability. It slotted into the IS lineup between the more affordable IS 200t (turbocharged four-cylinder) and the more powerful IS 350 (3.5-liter V6). The facelift brought revised styling, including a more aggressive spindle grille and updated interior trim. The IS 300 AWD aimed to appeal to buyers seeking a refined driving experience with the added security of all-wheel drive. Production continued until 2020, making it a relatively short-lived but significant variant within the XE30 generation.

Powertrain & Engine Architecture

At the heart of the IS 300 AWD lies the 2GR-FKS 3.5-liter naturally aspirated V6 engine. This engine is a member of Lexus’s GR family, known for its durability and smooth power delivery. The 2GR-FKS utilizes both direct injection (D-4S) and port injection to optimize combustion efficiency and reduce emissions. The D-4S system allows for precise fuel delivery at both low and high engine speeds. The engine also features Dual Variable Valve Timing with intelligence (D-VVT-i) on both intake and exhaust valves, further enhancing performance and fuel economy. Paired with this engine is a six-speed automatic transmission (ECT – Electronically Controlled Transmission) specifically tuned for smooth shifts and responsive acceleration. The transmission is designed to work seamlessly with the all-wheel-drive system, distributing power to all four wheels as needed.

Driving Characteristics

The IS 300 AWD delivers a comfortable and composed driving experience. While not as overtly sporty as the IS 350, the 260 horsepower V6 provides ample power for everyday driving and confident passing maneuvers. The six-speed automatic transmission offers smooth and predictable shifts, although it may not be as quick-shifting as some of the newer eight or ten-speed automatics found in competitors. The all-wheel-drive system provides enhanced traction in inclement weather, making it a practical choice for regions with snow or rain. Compared to the rear-wheel-drive IS 300, the AWD variant exhibits slightly more understeer, but this is a trade-off for increased stability. The gear ratios are optimized for a balance of acceleration and fuel efficiency, with a focus on providing usable torque in the mid-range.

Equipment & Trim Levels

The IS 300 AWD typically came well-equipped with standard features such as Lexus Safety System+, which included 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 7-inch screen, and Bluetooth connectivity. Optional extras included a Mark Levinson premium sound system, a larger 10.3-inch display screen, navigation, and blind-spot monitoring with rear cross-traffic alert. Trim levels were relatively streamlined, with most IS 300 AWD models offering a similar level of standard equipment. Packages were available to add specific features, allowing buyers to customize their vehicle to their preferences.

Chassis & Braking

The IS 300 AWD utilizes a double-wishbone front suspension and an independent multi-link rear suspension, both designed to provide a comfortable ride and precise handling. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock brakes (ABS) and Electronic Brake-force Distribution (EBD) are standard features. The AWD system itself adds some weight compared to the rear-wheel-drive models, which slightly impacts handling dynamics. The suspension tuning is geared towards comfort, but still offers a reasonably engaging driving experience.

Market Reception & Comparison

The IS 300 AWD was generally well-received by automotive critics, who praised its comfortable ride, refined interior, and standard safety features. However, some reviewers noted that its performance was not as exhilarating as the IS 350, and its fuel economy was not class-leading. Compared to the IS 200t, the IS 300 AWD offered a significant power upgrade, but at a higher price point. Against competitors such as the Acura TLX and BMW 3 Series, the IS 300 AWD offered a compelling value proposition, particularly for buyers prioritizing reliability and luxury. Fuel economy figures averaged around 22 mpg combined, which was typical for a V6-powered all-wheel-drive sedan of its time.

Legacy

The Lexus IS 300 AWD, with its 2GR-FKS engine and six-speed automatic transmission, has proven to be a reliable and durable powertrain combination. The 2GR engine family is known for its longevity, and the six-speed automatic is generally considered to be a robust transmission. On the used car market, these models hold their value relatively well, thanks to Lexus’s reputation for quality and reliability. While not a particularly rare or collectible variant, the IS 300 AWD remains a popular choice for buyers seeking a comfortable, well-equipped, and dependable luxury sedan.
