2009 Lexus LS IV (facelift 2009) Dimensions, Size & Specs

The curb weight of the Lexus LS IV (facelift 2009) ranges from 1955 kg to 2290 kg (approximately 4310 to 5049 pounds), reflecting the weight of the vehicle with standard equipment and all necessary fluids but without passengers or cargo. The maximum weight—meaning the total allowable weight including passengers, cargo, and the vehicle—is between 2495 kg and 2795 kg (about 5501 to 6160 pounds). This weight variation depends on the specific model, trim, and equipment fitted. The relatively high curb weight underscores the car's sturdy build, luxurious features, and advanced safety equipment, all of which contribute to a solid and refined driving experience.

The Lexus LS IV (facelift 2009) offers a ride height or ground clearance of 145 mm (approximately 5.7 inches). This level of clearance strikes a balance between luxury sedan styling and practical usability, enabling the vehicle to navigate most urban and highway environments with ease. While not designed for off-road conditions, the 145 mm ground clearance helps maintain a low center of gravity which benefits handling and stability, resulting in a smooth, composed ride. This clearance, however, requires drivers to be mindful of speed bumps and steep driveways to avoid scraping the underside.

The facelifted Lexus LS IV offers different wheel and tire configurations depending on the trim and options. The rims come in sizes 8J x 19 inches and 7.5J x 18 inches. Correspondingly, the tire sizes are 245/45 R19 for the 19-inch wheels and 235/50 R18 for the 18-inch wheel setup. These tire sizes complement the car's large and luxurious stance, offering a balance between ride comfort and handling performance. The availability of larger 19-inch wheels enhances style and road grip, while the 18-inch setup may provide a slightly softer ride quality.

The luggage capacity of the Lexus LS IV facelift ranges between 420 to 560 liters (around 14.8 to 19.8 cubic feet), a generous space for a luxury sedan. This capacity allows for ample storage of luggage and shopping bags, comfortably accommodating the needs of travelers and daily commuters alike. Compared to other vehicles in the full-size luxury segment, this cargo volume is competitive, often surpassing some German rivals like the Mercedes-Benz S-Class and BMW 7 Series, especially when rear seats are folded or configured for extended storage. The trunk design is practical, making loading and unloading easier despite the wide opening.

The Lexus LS IV (facelift 2009), with a length of 5060 mm (199.2 inches) and width of 1875 mm (73.8 inches), is a sizable full-size sedan. Standard single-car garages generally measure around 3000 mm to 3300 mm (10 to 11 feet) in width and 5400 mm to 6000 mm (18 to 20 feet) in length, so the LS IV should fit lengthwise with some room to spare. However, due to its width nearing 1.9 meters, comfortable side clearance might be limited depending on garage width and any storage or obstructions inside the garage. Overall, the LS IV will fit in a standard garage typical in North America and Europe, but maneuvering may require careful attention.

Compared to its predecessor, the third-generation Lexus LS (produced until 2006), the LS IV facelift 2009 brought subtle dimensional updates while maintaining the fundamental luxury sedan proportions. The fourth generation LS measures 5060 mm (199.2 inches) in length, slightly longer than the previous generation, which was around 5000 mm (196.9 inches). The width at 1875 mm (73.8 inches) is also marginally wider than before, improving interior space and road presence. Height varies slightly between 1455 mm and 1480 mm (57.3 to 58.3 inches), comparable to the predecessor. Overall, these dimensional changes translate into a more spacious and imposing vehicle without drastically altering the familiar silhouette.

The Lexus LS IV (facelift 2009) stands tall among flagship luxury sedans like the Mercedes-Benz S-Class, BMW 7 Series, and Audi A8 of the same period. Dimensionally, it is competitive with a length of 5060 mm (199.2 inches), width of 1875 mm (73.8 inches), and height ranging from 1455 mm to 1480 mm (57.3 to 58.3 inches). Its luggage capacity of 420 to 560 liters also matches or surpasses many rivals, delivering excellent practicality. The vehicle emphasizes ride comfort, reliability, and a refined interior. While German rivals may emphasize sportier handling or high-tech features, the LS IV offers a smooth, quiet ride and top-tier craftsmanship, making it a solid choice for buyers seeking Japanese luxury.

Thanks to its generous dimensions, the Lexus LS IV (facelift 2009) offers a spacious and luxurious interior environment. Its length and width contribute to ample legroom and shoulder room for both front and rear passengers, important for comfort during long trips. The height, while modest for a full-size sedan, still allows for a comfortable seating posture. Inside, Lexus integrates high-quality materials, advanced technology, and ergonomically designed seats, often heated and ventilated, to complement the spacious cabin. The overall size provides a sanctuary feel with excellent noise insulation, making it a quintessential full-size luxury sedan experience.

The tire and rim sizes of the Lexus LS IV facelift and their interplay are crucial to balancing performance, comfort, and aesthetics. The available 19-inch rims paired with 245/45 R19 tires provide a sportier stance and enhanced grip by offering a wider contact patch and lower profile tires, which improve handling responsiveness and cornering stability. Meanwhile, the 18-inch rims with 235/50 R18 tires prioritize cushioning over sporty dynamics, providing a softer and more comfortable ride by better absorbing road imperfections. Choosing between these tire and rim sizes allows buyers to tailor the LS's ride characteristics to their preferences without sacrificing the luxury feel.
