2009-2012 Lexus LS IV Long (facelift ) 460 L V8 (380 Hp) Super ECT

The Lexus LS 460 L, specifically the facelifted version produced from October 2009 to 2012, represents the fourth generation of Lexus’ flagship sedan. Positioned as the long-wheelbase variant of the LS 460, it prioritized rear passenger comfort and luxury without sacrificing the performance expected of a full-size luxury vehicle. This iteration of the LS, known internally as the UVF40 series, continued Lexus’ commitment to refinement, technology, and reliability, competing directly with established German rivals like the BMW 7 Series and Mercedes-Benz S-Class. The “L” designation signifies an extended wheelbase, adding approximately 3.9 inches (100 mm) to the overall length, almost all of which benefits rear legroom.

Powertrain & Engine Architecture

The heart of the LS 460 L is the 1UR-FSE 4.6-liter V8 engine. This naturally aspirated powerplant utilizes a combination of direct injection (D-4S) and multi-port fuel injection to optimize combustion efficiency and power delivery. The D-4S system allows for both stratified charge operation at low loads for improved fuel economy and homogeneous charge operation at higher loads for increased power. The engine features a dual variable valve timing system (Dual VVT-iE) on both intake and exhaust valves, further enhancing performance and responsiveness. The 1UR-FSE produces 380 horsepower at 6400 rpm and 367 lb-ft of torque at 4100 rpm. Paired with this engine is Lexus’ eight-speed Super ECT automatic transmission. This transmission is designed for smooth and seamless shifts, contributing to the overall refined driving experience. The transmission features manual shift mode, allowing the driver some control over gear selection.

Driving Characteristics

The LS 460 L with the 4.6L V8 and eight-speed automatic delivers a comfortable and composed driving experience. While not overtly sporty, the engine provides ample power for effortless acceleration and highway cruising. The 0-60 mph sprint takes approximately 5.4 seconds. The eight-speed transmission is well-tuned, offering smooth and almost imperceptible gear changes. Compared to potential alternatives like the LS 600h hybrid, the 460 L prioritizes a more traditional, linear power delivery. The longer wheelbase contributes to a more stable and comfortable ride, particularly noticeable on uneven road surfaces. The steering is light and precise, but lacks the feedback preferred by more enthusiastic drivers.

Equipment & Trim Levels

The LS 460 L came generously equipped as standard. Typical features included leather upholstery, wood trim, a premium sound system (Mark Levinson was an option), navigation system, power-adjustable and heated/ventilated front seats, rear seat climate control, and a power-operated rear sunshade. Optional extras included adaptive cruise control, a pre-collision system, and an air suspension system that further enhanced ride quality. The interior design emphasized luxury and comfort, with high-quality materials and meticulous attention to detail. The facelifted 2009 model received minor interior updates, including revised trim materials and updated infotainment system graphics.

Chassis & Braking

The LS 460 L utilizes an independent multi-link suspension system at both the front and rear. An optional air suspension system was available, providing adjustable ride height and damping for an even more refined ride. The braking system consists of ventilated discs at all four corners, providing ample stopping power. Anti-lock brakes (ABS) and electronic brake-force distribution (EBD) are standard features. The car’s substantial weight (approximately 4332-4460 lbs) necessitates a robust braking system to ensure confident stopping performance.

Market Reception & Comparison

The Lexus LS 460 L was generally well-received by automotive critics. It was praised for its luxurious interior, smooth ride, quiet cabin, and strong engine. However, some critics noted that the car lacked the sporty handling characteristics of some of its European rivals. Compared to the LS 600h hybrid, the 460 L offered a lower price point and a more traditional driving experience. Fuel economy, while respectable for a full-size luxury sedan, was not a standout feature, averaging around 16 mpg city and 24 mpg highway. Reliability was a key strength, with the LS 460 L consistently ranking highly in consumer reports.

Legacy

The Lexus LS 460 L, including the 2009-2012 facelifted models, has proven to be a remarkably reliable vehicle. The 1UR-FSE engine is known for its durability and longevity, and the eight-speed automatic transmission has also proven to be dependable. On the used car market, these LS models represent a good value for buyers seeking a luxurious and reliable full-size sedan. Maintenance costs are generally reasonable, although preventative maintenance, such as regular fluid changes, is crucial to ensure long-term reliability. The LS 460 L remains a testament to Lexus’ commitment to quality and refinement.
