2019 Kia K9 II Dimensions, Size & Specs

The curb weight of the Kia K9 II ranges between 1915 kg and 2165 kg (4220 to 4770 lbs), depending on trims and equipment levels. The heavier models generally include more luxury features and advanced technology, which can slightly dampen acceleration but improve ride comfort and stability. The weight classifies the K9 II firmly within the full-size luxury sedan segment, influencing handling dynamics and fuel efficiency accordingly.

The Kia K9 II comes with rim sizes of 18 or 19 inches and tire sizes of 245/50 R18, 245/45 R19 98W, and 275/40 R19 101W. Larger 19-inch wheels with wider tires offer enhanced grip and a sportier ride, whereas 18-inch wheels prioritize ride comfort and smoothness. The tire width and profile balance road handling with ride quality, contributing to the K9 II’s luxury driving experience.

A standard single-car garage typically measures about 3 meters (approximately 9.8 feet) in width and 6 meters (19.7 feet) in length. The Kia K9 II, at 5120 mm (201.6 inches) long and 1915 mm (75.4 inches) wide, will fit into most standard garages comfortably with some margin for opening doors and maneuvering. However, clearance may be tighter for garages with smaller interior dimensions or added storage encroachments.

Compared to the first-generation Kia K9, the K9 II is larger and more refined in dimensions. While exact predecessor measurements vary slightly, the K9 II’s length of 5120 mm (201.6 in) and width of 1915 mm (75.4 in) generally represent an increase, providing more interior space and a more dominant exterior presence. This size growth supports added luxury features and passenger comfort, as Kia positioned the II generation more firmly against established full-size luxury sedans.

The Kia K9 II is competitive in size with other full-size luxury sedans such as the Genesis G90, Mercedes-Benz S-Class, and BMW 7 Series. Its length at 5120 mm (201.6 inches) and width at 1915 mm (75.4 inches) align closely with these rivals, offering similar spaciousness and road presence. While some competitors may have marginally greater length or width, the K9 II’s dimensions sufficiently position it as a large and luxurious sedan in the premium market segment.

Although specific interior dimensions are not provided, the Kia K9 II’s large exterior size (5120 mm length and 1915 mm width) translates into a spacious cabin with ample legroom and headroom for both front and rear passengers. The vehicle’s wide stance and long wheelbase typically allow for comfortable seating positions, generous rear legroom, and a luxurious environment that rivals similarly sized luxury sedans. Kia’s emphasis on luxury features also enhances passenger comfort.

The Kia K9 II’s substantial size and curb weight (1915-2165 kg) generally mean fuel consumption is higher than that of smaller sedans due to increased mass and frontal area. In terms of handling, the weight and size provide stability at highway speeds and a smooth ride, but reduce agility and cornering sharpness compared to lighter, smaller vehicles. Suspension tuning and advanced technologies help maintain a balance between ride comfort and handling dynamics adequate for a luxury sedan.

The Kia K9 II offers tire options including 245/50 R18, 245/45 R19 98W, and 275/40 R19 101W, with rim diameters of either 18 or 19 inches. The 18-inch tires generally provide a more cushioned, comfortable ride ideal for luxury cruising, whereas the 19-inch options offer enhanced cornering grip and a sportier feel, but may transmit more road imperfections. The wider 275 mm tires improve traction and stability, especially at higher speeds or during aggressive driving.

The Kia K9 II, produced from 2018 to 2021, introduced a more contemporary and sophisticated exterior design with sharper lines and a more imposing front grille compared to its predecessor. It incorporated updated technology, safety features, and enhanced luxury appointments inside the cabin. The second generation also improved ride comfort through suspension upgrades and noise insulation, alongside expanded engine options. These enhancements helped the K9 II better compete in the full-size luxury sedan segment.
