2008 Lexus GS III (facelift 2008) Dimensions, Size & Specs

Compared to the previous generation GS II, the Lexus GS III facelift introduced in 2008 saw some subtle refinements in size and style. While the length remained roughly similar at around 4825 mm, improvements in width and height were made to offer better cabin comfort and a more aggressive stance. The adjustments mainly focused on enhancing the vehicle’s presence and aerodynamics without making it significantly larger. Changes in curb weight, now ranging from 1680 to 1875 kg, reflect additional features and structural reinforcements. Overall, the facelift refined the GS series within a familiar footprint, balancing luxury and sportiness with modernized styling.

The curb weight of the 2008 Lexus GS III facelift ranges from 1680 kg to 1875 kg (3704 to 4133 lbs), depending on the specific model and options such as engine type, drivetrain, and added features. This weight range is typical for mid-size executive sedans incorporating advanced safety and luxury elements. The relatively hefty curb weight provides a solid and stable driving experience, improving ride quality and road grip, but it can slightly impact fuel efficiency compared to lighter competitors. However, Lexus balances this by integrating efficient powertrains and technologies aimed at optimizing fuel consumption without compromising performance.

The Lexus GS III facelift from 2008 offers a luggage capacity ranging between 300 liters and 430 liters (approximately 10.6 to 15.2 cubic feet). This range depends on whether the rear seats are in use or folded down, as well as specific model variants. With this luggage space, the GS III can handle everyday grocery runs, business trips, or weekend getaways comfortably. The trunk size is competitive within its class, providing ample room for suitcases, briefcases, and other essentials. While the sedan body style limits very large or irregularly shaped cargo, the GS III strikes a practical balance for families and professionals alike.

Yes, the 2008 Lexus GS III facelift, with an overall length of 4825 mm (189.8 inches), width of 1820 mm (71.7 inches), and height of up to 1435 mm (56.5 inches), comfortably fits into most standard residential garage spaces. Standard garage dimensions typically range around 2400-3000 mm (94-118 inches) wide and at least 4800 mm (189 inches) deep, which accommodates the GS III with some room to spare for comfortable door opening and movement around the vehicle. However, owners should ensure their garage depth allows some margin to prevent tight squeezes, especially considering mirrors and additional clearance for passenger comfort.

The ground clearance of the 2008 Lexus GS III facelift ranges from 130 mm to 140 mm (about 5.1 to 5.5 inches). This relatively modest ride height is typical for luxury executive sedans, emphasizing lowered stance for improved handling and aerodynamics rather than off-road capability. Such clearance is adequate for most urban and highway conditions but may feel limited over very rough or uneven terrain, speed bumps, or steep driveways. Drivers should exercise caution in such environments to avoid undercarriage damage. However, this clearance contributes to the car’s smooth ride characteristics and stability at higher speeds.

The 2008 Lexus GS III facelift comes equipped with a variety of rim and tire size options that cater to different driving preferences. Rim sizes available include 7J x 17, 7.5J x 17, and 8J x 18, matched with tire sizes of 225/50 R17 or 245/40 R18. Larger 18-inch rims with wider tires typically enhance handling and road grip by providing a larger contact patch with the road, offering sharper cornering and improved stability at high speeds. Conversely, 17-inch wheels might provide a slightly softer ride due to taller tire profiles absorbing road imperfections better. Lexus balanced these choices to deliver both comfort and performance tailored to driver needs.

The interior headroom of the Lexus GS III facelift (2008) benefits from its height range of 1425 mm to 1435 mm (56.1 to 56.5 inches), offering comfortable space for most adult passengers. This overall height supports sufficient roof clearance in both front and rear seats, contributing to better occupant comfort on longer journeys. Width of 1820 mm (71.7 inches) translates to ample shoulder room, allowing three passengers to sit in the rear seat with reasonable space. Lexus focused on delivering an upscale experience with spacious seating and ergonomics that make the GS III suitable for both daily commuting and executive-level travel.

The 2008 Lexus GS III facelift competes in the mid-size executive sedan segment alongside the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6. Dimensionally, it aligns closely with these competitors, offering a length of 4825 mm (189.8 inches), width of 1820 mm (71.7 inches), and height roughly between 1425 and 1435 mm (56.1 to 56.5 inches). The GS III provides competitive interior space and luggage capacity, combining luxury with practicality. Lexus emphasizes reliability and comfort, which may appeal to buyers prioritizing long-term durability and a smooth driving experience. In contrast, European rivals may offer sportier driving dynamics or more cutting-edge technology features. Overall, the GS III balances size, comfort, and usability well within its class.

The 2008 Lexus GS III facelift has a maximum roof load capacity of 75 kg (165 lbs), meaning it can safely support roof racks, cargo boxes, or sports equipment such as bikes and skis up to this weight. This limit is designed to protect the vehicle's structural integrity and maintain stable handling characteristics. When using roof accessories, owners should ensure proper installation and weight distribution to avoid damage to the roof or interference with vehicle aerodynamics. The 75 kg capacity is typical for sedans in this segment and is sufficient for common roof cargo needs, making the GS III versatile for active lifestyles without compromising luxury.
