2025 MG RX9 Dimensions, Size & Specs

The 2025 MG RX9 offers a generous luggage capacity of 1026 liters (36.2 cubic feet) with the rear seats up, highlighting its practicality for everyday use and family outings. This volume is ideal for carrying large suitcases, sports equipment, or grocery loads without sacrificing passenger comfort. For longer trips or when more cargo space is required, folding down the rear seats can significantly enhance storage capacity, allowing bulky or oversized items to be transported with ease. Its cargo space positions the RX9 favorably among midsize SUVs, providing a versatile option that balances passenger comfort and practical storage solutions.

The MG RX9 has a width of 1967 mm (77.4 inches) and a height of 1786 mm (70.3 inches). The relatively wide stance improves stability during highway driving and cornering, and it enhances interior shoulder room, allowing adults to sit comfortably side-by-side without feeling cramped. The SUV's height provides ample headroom for passengers, contributing to an airy and spacious cabin experience. From a parking perspective, while the vehicle's width may require attention in narrow parking spaces, the height confirms the RX9 fits within typical garage door clearances. Drivers should still be cautious of height restrictions in parking garages or urban environments with low clearance.

Standard residential garages vary but typically measure about 2.4 to 3 meters (7.9 to 9.8 feet) in width and roughly 2 to 2.4 meters (6.5 to 7.9 feet) in height. With the MG RX9's width at 1967 mm (77.4 inches) and height at 1786 mm (70.3 inches), it generally fits comfortably within most standard garages in terms of overall dimensions. The SUV's width leaves just enough margin for door clearance while the height is well below typical garage door heights. However, owners should consider any custom garage features, additional items stored inside, or tight parking maneuvers. Also, the length of 4.98 meters (16.3 feet) fits most standard garage depths, but exact measurements of your garage are recommended for confirmed fit.

As the 2025 MG RX9 is the latest generation and MG’s flagship SUV launched in 2024 with no direct predecessor model in the RX series, there isn’t a previous generation RX9 to compare it to. However, compared to other previous MG SUVs such as the MG RX5, the RX9 represents a step up in both size and premium space offerings. The RX9 is larger in length, width, and height, translating to enhanced interior comfort, more seating capacity, and greater luggage volume. This new generation focuses on increased road presence, versatility, and upscale SUV features, significantly differentiating it from MG’s smaller SUV models and showcasing MG’s expansion into a more spacious, premium SUV segment.

The MG RX9’s dimensions place it firmly in the midsize SUV category, comparable to rivals such as the Toyota Highlander, Volkswagen Tiguan Allspace, and Hyundai Santa Fe. At 4983 mm (196.2 inches) in length, it is on the longer side, giving it an edge in interior space and third-row seating comfort. Its width of 1967 mm (77.4 inches) is competitive, providing ample passenger space without being unwieldy for urban driving. Height at 1786 mm (70.3 inches) also matches typical midsize SUVs, offering good headroom and a commanding driver view. The RX9’s luggage capacity of 1026 liters (36.2 cubic feet) is among the larger offerings in the segment, affirming its capability for family and cargo hauling. Overall, the MG RX9 balances spaciousness with usability, making it an attractive option in its class.

The MG RX9 offers rim options in 20-inch and 21-inch diameters. Correspondingly, the tire sizes available are 245/50 R20 and 255/45 R21. Larger rims with low-profile tires, such as the 21-inch option, tend to enhance handling precision and contribute to sportier road feel by reducing tire sidewall flex during cornering. However, they can also lead to a firmer ride over rough surfaces. The 20-inch rims with 245/50 tires offer a balanced compromise between ride comfort and performance, providing better impact absorption on uneven roads. These options allow owners to choose between comfort-oriented driving or more dynamic handling characteristics depending on preferences and typical driving conditions.

Specific curb weight figures for the MG RX9 have not been formally released. However, based on its size and class, it is estimated to weigh approximately 1800 to 2000 kg (3968 to 4409 lbs). A mid-to-high curb weight typical for a midsize SUV of these dimensions influences fuel consumption, acceleration, and braking performance. Heavier vehicles usually consume more fuel, particularly in city driving, but often provide better ride stability and a more solid feel on highways. The RX9’s weight is balanced to optimize both comfort and performance, utilizing modern engine technologies and lightweight materials where possible to maintain competitive fuel efficiency and responsive driving dynamics within its segment.

The MG RX9 is built as a spacious midsize SUV typically supporting 6 to 7 passengers, often configured in a 2-3-2 or 2-2-3 seating layout depending on trim and market. The nearly 5-meter length and wide body contribute to roomy interiors, providing ample legroom and headroom across all rows. This makes the RX9 an excellent choice for larger families or groups seeking comfort on longer trips. Its design prioritizes passenger space, including wide seats and generous shoulder room from its 1967 mm (77.4 inches) width. The SUV’s height ensures sufficient headroom, avoiding cramped sensations even for taller passengers seated in the third row.

Given the MG RX9’s substantial dimensions—length of 4983 mm (196.2 inches) and width of 1967 mm (77.4 inches)—it requires some adjustment when driving in tight urban settings or narrow streets. However, the SUV is equipped with advanced driver assistance technologies such as parking sensors, 360-degree cameras, and potentially automated parking systems that help mitigate challenges in close quarters. Its turning radius and visibility from the elevated driving position aid maneuverability. Drivers benefit from features designed to make city driving more comfortable and safer despite its larger footprint, making the RX9 practical for both open highways and crowded urban environments.
