2007 Lexus LS IV Dimensions, Size & Specs

The width of the Lexus LS IV is 1875 mm, which translates to approximately 73.8 inches or 6.15 feet. This width provides generous shoulder room for passengers and contributes to the vehicle's stable and planted handling characteristics. The relatively wide stance helps ensure a comfortable ride and enhances the luxury feel by allowing more space inside the cabin for features and seating comfort.

The height of the Lexus LS IV is 1465 mm, which is roughly 57.7 inches or 4.8 feet. This height is typical for a luxury sedan of this class, striking a balance between an elegant low profile and sufficient headroom inside the cabin. The lower height also assists in reducing aerodynamic drag, thereby improving fuel efficiency and contributing to a sleek exterior appearance.

The curb weight of the Lexus LS IV ranges from 1945 kg to 2270 kg, translating to approximately 4,287 to 5,005 pounds. This weight range reflects variations in trim levels, optional equipment, and drivetrain configurations. The relatively heavy weight is typical for a luxury sedan equipped with numerous comfort, safety, and technology features, contributing to a solid, stable ride at higher speeds.

The Lexus LS IV has a maximum weight or gross vehicle weight rating (GVWR) between 2495 kg and 2730 kg, which is approximately 5,499 to 6,018 pounds. This rating includes the weight of the vehicle itself, passengers, cargo, and fuel. Such high GVWR values ensure that the LS IV is built to handle substantial loads comfortably while maintaining performance and safety standards expected from a flagship luxury sedan.

The luggage capacity of the Lexus LS IV ranges from 420 to 565 liters, which is roughly 14.8 to 20 cubic feet. This spacious trunk volume is quite generous for a luxury sedan, allowing owners to carry substantial amounts of luggage or shopping comfortably. The variability in luggage space depends on certain trim levels and optional equipment that might slightly reduce cargo space, but overall, the LS IV offers excellent practicality alongside its luxurious cabin.

The Lexus LS IV features a ride height or ground clearance of 145 mm, equivalent to approximately 5.7 inches. This relatively low clearance enhances vehicle aerodynamics and stability on the road, contributing to a smooth ride and excellent handling characteristics expected from a flagship luxury sedan. However, it also means the vehicle is less suited for rough or unpaved roads, focusing more on comfort and on-road performance.

The Lexus LS IV comes with rim sizes of 8J x 19 inches or 7.5J x 18 inches, paired with tire sizes of 245/45 R19 or 235/50 R18, respectively. Larger 19-inch rims with low-profile tires typically enhance handling performance and road grip, ideal for sporty driving dynamics. Conversely, the 18-inch wheels with slightly taller tires prioritize ride comfort by providing more cushioning over bumps and imperfections. Lexus offers these options to balance driving pleasure with luxury comfort, depending on customer preference.

Fitting the Lexus LS IV into a standard garage is generally feasible but can be tight due to its length and width. With a length of 5030 mm (198 inches/16.5 feet) and width of 1875 mm (74 inches/6.15 feet), it occupies substantial space. Standard residential garages in many regions are around 6 meters (20 feet) deep and 2.4 to 2.7 meters (8 to 9 feet) wide. While the LS IV fits within these dimensions, maneuvering might be snug, especially considering door clearance and space to open doors fully. Owners should measure their garage carefully to ensure comfortable access.

The Lexus LS IV (2006-2009) exhibits notable dimensional changes compared to its predecessor, the LS III (1994–2000). The LS IV is longer, at 5030 mm compared to approximately 4975 mm of the LS III, making it about 5.5 cm (2.2 inches) longer, enhancing rear legroom and interior spaciousness. The width increased to 1875 mm from roughly 1875 mm (unchanged), maintaining a wide and stable stance. Additionally, the curb weight rose from about 1870 kg to as much as 2270 kg reflecting added safety, technology, and luxury features. Overall, the LS IV offers a more spacious and refined experience while retaining the flagship luxury sedan stature of its predecessor.

The Lexus LS IV competes with full-size luxury sedans such as the Mercedes-Benz S-Class, BMW 7 Series, and Audi A8. Dimensionally, the LS IV’s length of 5030 mm (198 inches) and width of 1875 mm (74 inches) are competitive, often slightly longer than some rivals, which emphasizes its spaciousness. Its luggage capacity of up to 565 liters (20 cubic feet) is also comparable or superior to competitors, reflecting strong practicality. Lexus emphasizes smooth ride quality, reliability, and plush interiors over outright sporty handling found in German rivals. The combination of size, luxury features, and reputation for reliability makes the LS IV a compelling alternative in this elite segment.
