Powertrain & Engine Architecture
At the heart of the LS 460 AWD is the 1UR-FSE, a 4.6-liter (4608 cc) naturally aspirated V8 engine. This engine utilizes Toyota’s D-4S direct-injection system, combining direct and port fuel injection for optimized combustion efficiency and power delivery. The engine features a double overhead camshaft (DOHC) valvetrain with Dual VVT-iE (Variable Valve Timing with electric motor), allowing for precise control of valve timing for improved performance and fuel economy. The 1UR-FSE produces 367 horsepower at 6400 rpm and 466 Nm (343.7 lb-ft) of torque at 4100 rpm. The engine’s robust construction and advanced technologies contribute to its smooth operation and reliability.
The engine is mated to an eight-speed automatic transmission, marketed by Lexus as “Super ECT.” This transmission offers smooth and responsive shifting, contributing to the overall refined driving experience. The AWD system is full-time, utilizing a viscous coupling center differential to distribute power between the front and rear axles, enhancing traction and stability in various driving conditions.
Driving Characteristics
The LS 460 AWD delivers a comfortable and composed driving experience. The 4.6-liter V8 provides ample power for effortless acceleration and highway cruising. While not a sports sedan, the LS 460 AWD can accelerate from 0 to 60 mph in approximately 5.9 seconds. The eight-speed automatic transmission contributes to smooth gear changes, and the AWD system provides confident handling in inclement weather. Compared to the rear-wheel-drive LS 460, the AWD version offers increased stability and traction, but with a slight increase in weight and fuel consumption. The gear ratios are tuned for a balance of performance and fuel efficiency, prioritizing smooth cruising over aggressive acceleration.
Equipment & Trim Levels
The LS 460 AWD typically came standard with a comprehensive list of luxury features, including leather upholstery, wood trim, a premium sound system, navigation system, power-adjustable and heated/ventilated front seats, and a power rear sunshade. Optional extras included a Mark Levinson premium audio system, adaptive cruise control, a pre-collision system, and a rear-seat entertainment system. The interior design emphasized comfort and elegance, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The LS 460 AWD features an independent multi-link suspension system at both the front and rear, providing a comfortable and controlled ride. Air suspension was available as an option, further enhancing ride quality and allowing for adjustable ride height. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock brakes (ABS) and electronic brake-force distribution (EBD) are standard features. The chassis is designed for rigidity and refinement, minimizing noise, vibration, and harshness.
Market Reception & Comparison
The Lexus LS 460 AWD was generally well-received by automotive critics, praised for its luxurious interior, smooth ride, and refined powertrain. However, some critics noted that the LS 460 AWD’s fuel economy was relatively low compared to some of its competitors. Compared to other LS 460 trims, the AWD version offered enhanced all-weather capability but came at a slight premium in price and fuel consumption. The LS 460 competed with other flagship luxury sedans such as the BMW 7 Series, Mercedes-Benz S-Class, and Audi A8.
Legacy
The Lexus LS 460, including the 2009-2012 facelifted model, has proven to be a reliable and durable luxury sedan. The 1UR-FSE engine is known for its longevity and relatively low maintenance requirements. In the used car market, the LS 460 AWD remains a popular choice for buyers seeking a comfortable, well-equipped, and reliable luxury sedan. While newer Lexus models have introduced more advanced technology and features, the LS 460 continues to offer a compelling combination of luxury, performance, and value.
