2007 Lexus LS IV Long Dimensions, Size & Specs

The Lexus LS IV Long offers a luggage capacity that ranges from 420 to 565 liters (approximately 14.8 to 20 cubic feet). This variability depends on the seating configuration and optional equipment that might affect trunk space, such as additional luxury or safety packages. The upper limit of 565 liters is quite generous for an executive sedan, allowing for multiple suitcases or large items, making it practical for extended trips where both passenger comfort and cargo volume are essential.

The curb weight of the Lexus LS IV Long varies from 2025 kg to 2290 kg (approx. 4464 to 5048 lbs), depending on trim and features installed. Its maximum authorized weight lies between 2465 kg and 2755 kg (about 5434 to 6073 lbs). The relatively heavy weight is typical for a large, luxurious sedan equipped with advanced safety and comfort technologies. While the weight contributes to a smooth and stable ride, it can slightly affect acceleration and fuel efficiency. However, Lexus balances the vehicle with powerful engine options and suspension tuning to maintain excellent handling characteristics despite its size.

The Lexus LS IV Long comes equipped with rims sized at 7.5J x 18 inches, 8J x 18 inches, or 8J x 19 inches depending on the trim and optional packages. Correspondingly, tire sizes include 235/50 R18 or 245/45 R19, designed to provide a blend of comfort, grip, and performance. Larger rims and tires on the 19-inch option enhance road handling and aesthetic appeal but may slightly influence ride softness compared to 18-inch wheels. The tire sizes and rim configurations were chosen to optimize the ride quality expected in the luxury full-size sedan segment.

The ride height (ground clearance) of the Lexus LS IV Long ranges from 135 mm to 145 mm (approximately 5.3 to 5.7 inches). This relatively low clearance supports better aerodynamics and handling characteristics typical for a luxury sedan, delivering a smooth and composed ride on paved roads. However, this modest ground clearance means the vehicle is best suited for urban and highway driving rather than rough or unpaved surfaces. Drivers should exercise caution over speed bumps or steep driveways to avoid scraping the undercarriage.

With an overall length of 5150 mm (202.8 inches) and width of 1875 mm (73.8 inches), the Lexus LS IV Long is a large vehicle that may challenge standard garage dimensions. Standard single-car garages typically range from 5400 to 6000 mm (213 to 236 inches) in length and around 2800 mm (110 inches) in width, so it will generally fit lengthwise but leaves limited extra space for storage or opening doors fully. Moreover, careful maneuvering might be needed in narrower or shorter garages. Homeowners with compact garages should measure carefully to ensure comfortable accommodation of this longwheelbase luxury sedan.

When compared to its predecessor (the Lexus LS III 2000-2006), the LS IV Long gained noticeable increases in length and interior space. The LS IV Long’s 5150 mm length notably surpasses the previous generation's approximate 5050 mm, adding roughly 10 cm (4 inches), primarily benefiting rear-seat legroom and overall passenger comfort. The increased length mostly results from the long-wheelbase designation, enhancing rear-seat luxury features such as extra legroom and improved ride quality. Width and height remained relatively stable between generations, so the main dimension gain focused on extending cabin length for a more prestigious chauffeur-driven experience.

The Lexus LS IV Long stands competitively among full-size luxury sedans of its era in terms of size and weight. For example, the 2007 Mercedes-Benz S-Class (long wheelbase) has a length of approximately 5250 mm and weight close to 2100-2300 kg, slightly longer but broadly similar in mass. The BMW 7 Series also shares comparable dimensions, though with slightly more aggressive weight-saving strategies. Overall, the Lexus LS IV Long's dimensions at 5150 mm length and weights up to 2290 kg position it solidly within the market segment, offering a balance of spaciousness, prestige, and heft that emphasize comfort and safety rather than outright sporty lightness.

The Lexus LS IV Long’s height varies from 1465 mm to 1480 mm (57.7 to 58.3 inches) depending on vehicle configuration and suspension setup. This height ensures sufficient headroom for front and rear passengers, which is critical in a luxury sedan designed for comfort. The slightly elevated roofline compared to sportier sedans means passengers, especially those in the rear long-wheelbase section, benefit from generous vertical space that reduces any sense of confinement. Though not classified as a tall vehicle, this height is well optimized to provide an airy, spacious cabin feel while maintaining sleek styling.

The Lexus LS IV Long (produced between 2006 and 2009) is a flagship full-size luxury sedan emphasizing a blend of traditional Japanese craftsmanship and modern technology. Designed to provide supreme rear-seat comfort, it features an extended wheelbase compared to standard LS models, enhancing legroom and ride quality for rear passengers. Technologically, it offers advanced safety features such as adaptive cruise control, pre-collision systems, and premium comfort elements including ventilated seats and high-end audio. Its engine options focus on smooth power delivery complemented by a sophisticated suspension setup that balances ride comfort with controlled handling, making it a preferred choice for executive or chauffeur-driven use.
