The Lexus LX 450d, specifically the facelifted model introduced in 2015 and continuing through October 2021, represents Lexus’s entry into the full-size luxury diesel SUV segment. Built upon the foundation of the Toyota Land Cruiser J200 platform, the LX 450d was primarily aimed at markets outside of North America, where diesel engines enjoy greater popularity. This variant, powered by a 4.5-liter turbocharged V8 diesel engine producing 272 horsepower and 650 Nm (479 lb-ft) of torque, coupled with a six-speed automatic transmission and full-time all-wheel drive, offered a blend of luxury, capability, and relatively improved fuel economy compared to gasoline-powered LX models. It occupied a mid-to-upper position within the LX lineup, offering a compelling alternative to the petrol V8 options.

Powertrain & Engine Architecture
The heart of the LX 450d is the 1VD-FTV, a 4.5-liter V8 diesel engine. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A sequential twin-turbocharger setup, coupled with an intercooler, enhances both power and torque output. The engine also features a dual Variable Valve Timing-intelligent (VVT-i) system, which adjusts valve timing on both the intake and exhaust sides to improve efficiency and responsiveness. The six-speed automatic transmission, while robust, is a somewhat older design compared to the eight or ten-speed automatics found in more contemporary luxury SUVs. It’s known for its reliability but can feel less refined in terms of shift smoothness and gear selection compared to newer transmissions.
Driving Characteristics
The LX 450d offers a distinctly different driving experience compared to its gasoline-powered siblings. The substantial torque available from low engine speeds (650 Nm between 1600-2800 rpm) provides effortless acceleration and strong pulling power, particularly useful for towing. While the 0-60 mph time of around 8.2 seconds isn’t particularly quick by modern standards, the engine’s responsiveness makes it feel more powerful in everyday driving situations. The automatic transmission, while reliable, can sometimes hunt for gears, especially during highway cruising. The LX 450d’s considerable weight (2510-2840 kg) is noticeable, impacting handling agility. However, the sophisticated full-time all-wheel-drive system provides excellent traction and stability in various conditions.
Equipment & Trim Levels
The LX 450d typically came well-equipped, reflecting its luxury positioning. Standard features generally included leather upholstery, power-adjustable front seats with heating and ventilation, a premium audio system, a navigation system, and a suite of safety features like ABS, stability control, and multiple airbags. Higher trim levels added features such as a rear-seat entertainment system, adaptive cruise control, and a more luxurious interior finish. Optional extras often included a sunroof, upgraded wheels, and various cosmetic enhancements.
Chassis & Braking
The LX 450d utilizes a body-on-frame construction, inherited from the Land Cruiser, providing exceptional durability and off-road capability. The suspension consists of double wishbones at the front and a multi-link setup at the rear. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The LX 450d’s substantial weight necessitates a robust braking system, and the ABS helps maintain control during hard braking. Stabilizer bars are present on both axles to reduce body roll during cornering.
Market Reception & Comparison
The LX 450d was generally well-received in markets where diesel SUVs were popular. Critics praised its powerful engine, comfortable ride, and luxurious interior. However, some noted the somewhat dated automatic transmission and the vehicle’s considerable weight. Compared to the gasoline-powered LX 570, the 450d offered improved fuel economy, making it a more attractive option for drivers covering long distances. Against competitors like the Range Rover and BMW X5, the LX 450d offered a unique blend of luxury, off-road capability, and diesel efficiency.
Legacy
The Lexus LX 450d has proven to be a reliable and durable SUV, benefiting from Toyota’s reputation for engineering excellence. The 1VD-FTV engine, while complex, is generally considered robust when properly maintained. On the used car market, the LX 450d holds its value relatively well, particularly examples with low mileage and a full service history. Its combination of luxury, capability, and diesel efficiency continues to appeal to buyers seeking a distinctive and long-lasting SUV.
