2016 Lexus RX IV Dimensions, Size & Specs

The Lexus RX IV has a body width of 1895 mm (74.6 inches). When including the extended side mirrors, the overall width increases to 2180 mm (85.8 inches). This extra width with mirrors extended is important to consider when parking in tight spaces or narrow garages. The wide stance improves stability and a commanding road presence while parking sensors and cameras assist with maneuvering given the width.

The Lexus RX IV stands between 1685 mm and 1720 mm tall (66.3 to 67.7 inches). The slight variation depends on factors such as wheel size and suspension setup. This height offers a balanced combination of interior headroom and a sleek SUV profile for refined aerodynamics. Despite its height, the RX IV retains good roofline styling, minimizing wind noise and drag while providing a comfortable upright seating position.

The curb weight of the Lexus RX IV ranges from 1915 kg to 2205 kg (4221 to 4860 lbs). The weight variation depends on engine type, drivetrain configurations (e.g., front-wheel drive or all-wheel drive), optional equipment, wheel size, and trim levels. Being a midsize luxury SUV, the RX IV balances luxury features and safety components while striving to optimize weight for performance and fuel economy.

The Lexus RX IV has a maximum gross weight ranging between 2500 kg and 2840 kg (5512 to 6263 lbs). This weight includes the vehicle's curb weight plus passengers, cargo, and any additional load. The higher end of this spectrum accommodates models with all-wheel drive and more robust equipment, ensuring safe operation under maximum load conditions.

In standard configuration, the Lexus RX IV offers a luggage capacity between 176 liters and 553 liters (6.2 to 19.5 cubic feet). Folding down the rear seats significantly increases this capacity to between 1612 liters and 1656 liters (56.9 to 58.5 cubic feet). This flexibility in cargo space caters to everyday urban needs as well as bulky item transportation, making it suitable for family outings or road trips.

A standard residential garage typically measures about 2440 mm (8 feet) wide and 4880 mm (16 feet) deep. The Lexus RX IV, with a length up to 5001 mm (196.9 inches) and mirror-open width of 2180 mm (85.8 inches), fits in most garages lengthwise only if mirrors are folded. While the body width of 1895 mm (74.6 inches) fits comfortably, the mirror width requires careful maneuvering or folding the mirrors to avoid scraping the garage walls. Its height of up to 1720 mm (67.7 inches) also fits typical garage door heights without issue.

Compared to the RX III generation, the RX IV is generally larger and more refined in dimensions. The RX IV's length ranges between 4890 mm and 5001 mm (192.5 to 196.9 inches), marginally longer than RX III which had lengths closer to approximately 4800 mm (189 inches). The width and height also increased slightly for the RX IV, enhancing interior space and road presence. These incremental size increases result in more cabin comfort, increased cargo space, and improved ride quality without sacrificing maneuverability.

The Lexus RX IV's dimensions place it comfortably in the midsize luxury SUV segment alongside rivals such as the BMW X5, Audi Q7, and Mercedes-Benz GLE. For example, the RX IV's length (up to 5001 mm) is generally comparable or slightly shorter than the Audi Q7 and BMW X5, which often exceed 5000 mm. Its width of 1895 mm without mirrors is competitive, providing ample interior space while still being manageable in urban environments. The RX IV emphasizes a balance between luxury space and daily usability, with competitive luggage capacity that meets or exceeds many rivals.

The Lexus RX IV comes equipped with rim sizes including 8J x 18, 8J x 20, and tire sizes such as 235/65 R18 and 235/55 R20. Larger 20-inch wheels (8J x 20) with 235/55 R20 tires contribute to a more commanding stance, improved handling, and a sportier aesthetic. Meanwhile, 18-inch wheels with 235/65 R18 tires prioritize comfort and a softer ride quality. These options allow owners to choose between performance-oriented setups or more comfort-focused driving characteristics.
