2014 Lexus IS III (XE30) Dimensions, Size & Specs

The curb weight of the Lexus IS III ranges between 1590 kg to 1760 kg (3507 to 3881 lbs), depending on the trim and equipment. A curb weight in this range provides a good balance between structural rigidity and overall vehicle dynamics. It helps the car maintain solid road grip and stability while allowing for relatively agile handling. The weight also impacts fuel efficiency and acceleration; the relatively light weight for a luxury sedan helps the Lexus IS III deliver responsive performance with its engine options.

The maximum gross vehicle weight (GVW) for the Lexus IS III (XE30) falls between 2035 kg and 2130 kg (4489 to 4696 lbs). This includes the weight of the vehicle itself plus passengers, cargo, and fuel. Knowing the max weight is crucial for safety and legal driving. Exceeding this limit can impair braking, handling, and suspension performance, and may cause premature wear on components. It also impacts insurance and vehicle inspection requirements in some regions.

The Lexus IS III sedan offers a luggage capacity ranging from 306 liters to 480 liters (approximately 10.8 to 16.9 cubic feet) depending on the configuration and whether rear seats are folded. This capacity is competitive for the compact executive sedan segment, making it practical for everyday use and short trips. While some rivals may offer slightly larger trunks, the IS prioritizes a sporty design which sometimes limits trunk space. Still, it balances passenger comfort with sufficient cargo room.

The ride height, or ground clearance, of the Lexus IS III ranges between 130 mm to 135 mm (approximately 5.1 to 5.3 inches). This relatively low ground clearance enhances the car’s aerodynamic profile and improves handling by lowering the center of gravity. However, it means the vehicle is better suited for smooth road surfaces and may require caution over speed bumps or rough terrain. The ride height strikes a balance between sporty driving characteristics and everyday usability.

The Lexus IS III offers a variety of tire and rim sizes to suit different trims and driving preferences. Rim sizes range from 16 inches to 18 inches, including 7J x 16, 8J x 18, 8.5J x 18, 7.5J x 18, and 7J x 17. Tire options include 205/55R16 91W, 225/40R18 88Y, 255/35R18 90Y, 225/45R17, 225/40R18, and 225/35R18. These options allow buyers to prioritize comfort, grip, or sporty handling, with wider performance tires available on higher trims.

Yes, the Lexus IS III fits comfortably into a standard garage. Standard garages typically measure around 2.4 to 2.7 meters (7.9 to 8.9 feet) wide and 5.5 to 6 meters (18 to 20 feet) deep. With a width of 1810 mm (71.3 inches) and a length of 4665 mm (183.7 inches), the Lexus IS III leaves ample room for entry and exit when the mirrors are closed. However, with mirrors opened at 2027 mm (79.8 inches), careful maneuvering may be required in tighter garage spaces. Height at 1430 mm (56.3 inches) is no issue for most garages.

Compared to its predecessor, the Lexus IS II, the IS III (XE30) is slightly longer and marginally wider but maintains a similar height. The IS II was shorter — typically around 4620 mm (181.9 inches) in length — so the IS III's length of 4665 mm (183.7 inches) offers a bit more cabin space and trunk volume. The width has also increased slightly from about 1775 mm (69.9 inches) to 1810 mm (71.3 inches), contributing to improved interior shoulder room. Overall, the IS III embraces a more aggressive and modern stance, with subtle dimensional growth to enhance comfort without compromising sporty dynamics.

The Lexus IS III compares closely with key competitors such as the BMW 3 Series and Audi A4 in the compact luxury sedan class. The IS III's length of 4665 mm (183.7 inches) is slightly longer than some versions of the 3 Series (approximately 4624 mm) and similar to mid-model A4s. Width-wise, it is 1810 mm (71.3 inches), narrower than the BMW 3 Series (around 1827 mm) but comparable to the Audi A4 (about 1847 mm). Ground clearance is lower compared to these rivals, emphasizing its sporty character. Overall, the Lexus IS III is dimensionally competitive, combining sleek styling with practical interior space.
