INTRODUCTION

The Lexus LS 460 L (2012-2017) represents the facelift of the fourth-generation LS, built on the XV40 platform. The “L” designation signifies the extended wheelbase version, offering significantly more rear passenger legroom. This model year brought revised styling, including a bolder front grille, updated interior materials, and enhanced technology features. The 4.6-liter V8 engine paired with an eight-speed automatic transmission and all-wheel drive was the flagship powertrain, emphasizing both performance and all-weather capability. It was positioned as the premium offering, above the standard wheelbase LS 460 and any hybrid variants.

Powertrain & Engine Architecture

At the heart of the LS 460 L lies the 1UR-FSE 4.6-liter V8 engine. This naturally aspirated engine utilizes a direct-injection and multi-port fuel injection system, maximizing both power and fuel efficiency. The engine boasts dual overhead camshafts (DOHC) with Lexus’s Variable Valve Timing with intelligence-Electric motor (VVT-iE) system, optimizing valve timing for improved performance across the rev range. The 1UR-FSE produces 370 horsepower at 6400 rpm and 473 Nm (348.87 lb-ft) of torque at 4100 rpm. The engine’s architecture is a 60-degree V-angle, contributing to a smooth and balanced operation. The engine is longitudinally mounted in the front of the vehicle. The eight-speed automatic transmission, marketed as “Super ECT,” provides smooth and responsive shifts. This transmission replaced the previous six-speed unit, improving both acceleration and fuel economy. The AWD system is full-time, utilizing a viscous coupling center differential to distribute power between the front and rear axles as needed.

Driving Characteristics

The LS 460 L 4WD delivers a driving experience focused on comfort and refinement. The 370 hp V8 provides ample power for effortless acceleration, achieving 0-60 mph in approximately 5.9 seconds. While not a sports sedan, the LS 460 L feels surprisingly agile for its size. The eight-speed automatic transmission is well-tuned, offering smooth gear changes and keeping the engine in its optimal power band. Compared to the standard wheelbase LS 460, the longer wheelbase of the “L” model results in a slightly softer ride, prioritizing rear passenger comfort. Compared to a hypothetical six-cylinder or hybrid LS variant, the V8 offers significantly more immediate power and a more traditional luxury car feel. The AWD system provides enhanced traction in inclement weather, making it a capable all-season vehicle.

Equipment & Trim Levels

The LS 460 L came standard with a comprehensive list of luxury features. Interior appointments included leather upholstery, wood trim, and a premium sound system. Standard equipment also included a navigation system, a rearview camera, heated and ventilated front seats, and a power-adjustable steering column. Optional extras included a Mark Levinson premium audio system, a rear-seat entertainment system, adaptive cruise control, and a pre-collision system. The “L” model also featured power-reclining rear seats with massage functions, further enhancing rear passenger comfort. Trim levels were relatively simple, with most options being added individually rather than packaged into distinct tiers.

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 an even smoother ride and the ability to adjust ride height. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated discs at all four corners, providing ample stopping power. The front brakes measure 358 mm, while the rear brakes measure 335 mm. An Anti-lock Braking System (ABS) is standard, along with Electronic Brake-force Distribution (EBD) and Brake Assist. The steering system is a rack-and-pinion setup with electric power steering.

Market Reception & Comparison

The Lexus LS 460 L was generally well-received by automotive critics. It was praised for its luxurious interior, smooth ride, and quiet cabin. However, some critics noted that its styling was conservative compared to its European rivals. Fuel economy, at 13.1 l/100 km combined, was considered average for a full-size luxury sedan. Compared to the standard LS 460, the “L” model offered superior rear passenger space, making it a popular choice for buyers who frequently transport passengers. Compared to the hybrid LS 600h L, the 460 L offered a more traditional driving experience and a lower price point, though with slightly lower fuel economy.

Legacy

The Lexus LS 460 L (2012-2017) continues to be a desirable used luxury car. The 1UR-FSE V8 engine is known for its reliability, provided it receives regular maintenance. While not the most fuel-efficient option in its class, the LS 460 L offers a compelling combination of luxury, performance, and dependability. The availability of genuine Lexus parts and a strong dealer network contribute to its continued appeal in the used car market. These models represent a high point in Lexus’s commitment to creating a refined and comfortable luxury experience.
