2012 Lexus RX III (facelift 2012) Dimensions, Size & Specs

The curb weight of the Lexus RX III facelift ranges from 1840 kg to 2110 kg (4058 to 4654 lbs), depending on the trim and equipment. This solid weight contributes to a stable and composed ride, typical of luxury SUVs, by providing a low center of gravity and enhanced road adherence. However, it may also slightly impact fuel efficiency compared to lighter crossovers but enhances overall safety and driving comfort.

With a ride height (ground clearance) of 185 mm (7.3 inches), the Lexus RX III facelift offers reasonable clearance for light off-road use and uneven urban terrain, such as speed bumps and potholes. While it’s primarily designed for on-road luxury SUV performance rather than heavy off-roading, this clearance ensures adequate protection and versatility for varied driving conditions without sacrificing comfort.

The Lexus RX III facelift delivers a practical cargo capacity ranging from 446 to 496 liters (15.7 to 17.5 cubic feet) with the rear seats upright. For greater flexibility, folding the back seats expands the storage volume impressively to 1570 liters (55.5 cubic feet). This makes the RX III a versatile SUV suitable for family trips, groceries, sports gear, or larger cargo needs.

The Lexus RX III facelift typically comes with rim sizes of 18 or 19 inches (7.5J x 18 and 7.5J x 19) paired with tires sized 235/60 R18 103V, 235/55 R19 101V, or variants thereof. Larger 19-inch rims usually provide a sportier aesthetic and improved cornering, while 18-inch rims favor ride comfort and better absorb road imperfections. The tire profiles and sizes strike a balance between grip, comfort, and handling suited for a luxury SUV.

Considering its length of 4770 mm (187.8 inches) and width of 1885 mm (74.2 inches), without mirrors, the Lexus RX III facelift generally fits comfortably into a standard single-car garage. The 2120 mm (83.5 inches) width with mirrors extended means some caution is needed when opening doors or maneuvering. However, its height between 1685 and 1720 mm (66.3 to 67.7 inches) is well within typical garage height clearances, making it practical for daily garage parking.

Compared to its predecessor, the RX II (2003-2008), the RX III facelift (2012-2015) is larger, offering increased length and width. While exact RX II dimensions vary slightly by year and trim, the RX III’s 4770 mm length and 1885 mm width represent a phase of growth aimed at improving interior space and road presence. This enlargement allows for enhanced passenger comfort and cargo capacity, reflecting evolving customer tastes in midsize luxury SUVs.

The Lexus RX III facelift positions itself as a midsize luxury SUV with a length of 4770 mm, width of 1885 mm, and luggage capacity up to 1570 liters. Compared to competitors like the BMW X5 and Audi Q7, the RX III is slightly shorter and narrower—X5s typically stretch beyond 4800 mm and Q7s are even longer. While the RX may fall slightly behind these rivals in sheer space and cargo volume, it emphasizes reliability, smooth ride quality, and luxurious features, appealing to buyers valuing comfort and refinement over maximum size.

The Lexus RX III facelift offers 18- and 19-inch wheel options with sizes of 7.5J x 18 and 7.5J x 19, matched with tire sizes such as 235/60 R18 and 235/55 R19. Larger 19-inch wheels typically improve handling responsiveness and cornering stability but might slightly reduce ride comfort due to lower-profile tires. The 18-inch wheels promote a smoother ride and better absorption of road irregularities, fitting well with the SUV’s luxury-oriented design.

The Lexus RX III facelift has a maximum weight ranging from 2410 kg to 2700 kg (5313 to 5952 lbs), depending on configuration. This figure includes curb weight plus allowable passengers, cargo, and optional equipment. These capacity figures ensure the SUV can comfortably handle a full passenger load with luggage or gear, maintaining safe handling characteristics and durability.
