Technical Superiority: The Foundation of the LX 600
GA-F Platform: Uncompromising Rigidity and Comfort
The 2023 LX 600 rides on the robust GA-F platform, which was introduced in the 2022 redesign. This platform is critical to achieving the Lexus Driving Signature, providing enhanced body rigidity for superior ride comfort and composed handling. Drivers will appreciate the predictable and balanced handling of the LX 600 during various maneuvers, both on and off the road. The platform also contributes to improved stability when venturing off the beaten path.
To balance exceptional off-road performance with refined on-road handling, the LX 600 utilizes a front high-mounted double-wishbone suspension. The suspension geometry and optimized coil springs work in harmony to deliver both vehicle stability and a comfortable ride. The suspension is engineered with a long stroke – 100 mm (3.93 in.) of bound and 145 mm (5.7 in.) of rebound – crucial for achieving exceptional performance across diverse terrains.
Twin-Turbo V6 Power and Direct Shift-10AT: Performance and Smoothness
At the heart of the LX 600 is a potent 3.4-liter V6 twin-turbo gasoline engine (V35A-FTS). This engine generates 409 horsepower (415 PS) and a substantial 479 lb.-ft. of torque. Importantly, the engine maintains peak torque across a broad rev range, up to approximately 3,600 rpm. This characteristic makes the LX 600 incredibly responsive and easy to control, whether navigating city streets or tackling challenging off-road trails at low speeds.
The engine is paired with the Direct Shift-10AT (10-speed automatic transmission), which combines the smooth launch feel of a torque converter with the direct acceleration sensation of a manual transmission. This is achieved through lockup activation across almost the entire operating range, except during initial start-up. The transmission’s close gear ratios and rapid shift times contribute to crisp and rhythmic gear changes, harmonizing with the engine’s sound to enhance the driving experience.
The wide gear ratio range of the 10-speed transmission further enhances both starting comfort and high-speed cruising efficiency. The low first gear ratio maximizes driving force at low speeds, providing a smooth initial launch and powerful low-speed off-road performance. For added durability in off-road environments, the automatic transmission is equipped with an oil pan guard, reducing the risk of damage from impacts to the undercarriage.
Lexus Driving Signature: Seamless On-Road Dynamics
The Lexus Driving Signature philosophy is further embodied in the LX 600 through the integration of the high-output twin-turbo engine, Electronically Controlled Brake (ECB), and Electric Power Steering (EPS) systems. These systems work together to deliver a driving experience characterized by seamless transitions between deceleration, steering, and acceleration. The Active Height Control (AHC) and Adaptive Variable Suspension (AVS) systems further enhance grip, traction, and control, providing a sense of confidence and security in all driving situations.
Active Height Control (AHC) and Adaptive Variable Suspension (AVS): Optimized Ride for Every Terrain
The Active Height Control (AHC) suspension is a key feature of the LX 600, allowing for adjustable ride height based on driving conditions. The system utilizes shock absorbers, gas and hydraulic springs, and metal springs to achieve a wide range of ride height positions. A spring rate switching device is incorporated in the rear suspension to minimize ride height adjustment time. The AHC system offers three on-road height settings (Normal, Hi1, and Hi2) and a Low setting for easier entry and exit.
The system intelligently adjusts vehicle height based on Drive Mode Select or Multi-Terrain Select settings, as well as transfer case status. Ride height information is conveniently displayed on both the gauge panel and the 7-inch touch display. Beyond ride height adjustment, AHC also actively responds to changes in vehicle posture, such as pitch and roll, optimizing spring rates to stabilize the vehicle during cornering, acceleration, and braking.
In off-road scenarios, the suspension automatically adjusts to Hi1 or Hi2 based on road conditions and Multi-Terrain Select mode. At higher speeds in Hi1 or Hi2 settings, the system automatically lowers the vehicle to enhance handling stability and minimize potential road surface interference. The suspension also adapts to driving style, softening for comfort over bumps in urban driving and stiffening for a flatter, more stable ride during cornering. The automatic vehicle lowering feature at standstill further enhances passenger convenience.
The Adaptive Variable Suspension (AVS) system employs linear solenoid valves for precise damping force control. This advanced system provides intricate and smooth adjustments based on road surface and driving conditions, further refining ride quality and handling.
Electric Power Steering (EPS) and Electronically Controlled Brake (ECB): Precise Control and Responsiveness
The Electric Power Steering (EPS) system in the LX 600 replaces traditional hydraulic systems with a motor and reduction gear. This allows for fine-tuned steering feel, offering light steering at low speeds (ideal for off-road maneuvering) and progressively weighting up at higher speeds. The EPS system ensures a linear and faithful response to driver input, contributing to the Lexus Driving Signature. The light steering feel at low speeds reduces driver fatigue, while the more substantial feel at higher speeds enhances confidence and control.
The Electronically Controlled Brake (ECB) system utilizes a sensor to precisely detect brake pedal input and modulates hydraulic braking force for more linear braking characteristics. When Multi-Terrain Select is engaged for off-road driving, the ECB system provides detailed braking control to maintain stability and minimize wheel slip or spin.
Wheels, Tires, and Rear Torsen® LSD: Optimized Traction and Performance
The LX 600 offers 22-inch forged aluminum wheels, the largest in the Lexus lineup, which contribute to both on-road and off-road performance. Exclusively on the F SPORT grade, a Torsen® Limited Slip Differential (LSD) enhances rear tire traction. During cornering acceleration, the Torsen® LSD optimally distributes driving force between the rear wheels based on load, maximizing control. In straight-line driving, it reacts quickly to changing road conditions, enhancing stability.
Heritage and Innovation: Building on a Legacy
The LX 600 proudly maintains the 2,850 mm (112-inch) wheelbase, a golden ratio carried over from the first generation LX in 1995. This wheelbase is a key factor in providing both exceptional off-road capability and a spacious interior. The LX 600 retains the impressive off-road geometry of its predecessors, including approach, departure, and ramp break angles, a 44-degree maximum stable inclination angle, a 45-degree climbing ability, and a 700 mm (27.5-inch) maximum river crossing depth.
