The SX4 Sedan is the saloon version of the SX4, Suzuki's third world-strategic model. It has the elegance and practicality of a saloon and – for its overall size – a particularly roomy interior, plus the convenience and utility of Suzuki's high-roof wagon, which is one of the core attractions of its vehicles. Suzuki sees the new saloon as an expression of "upright comfort-ism." The SX4 Sedan is stylish yet has the space to allow all occupants to sit with natural postures, and it also has the space that enables comfort expected of a notchback. A highly rigid body and rigid suspension mounts and links derived from the SX4 hatchback provide excellent driving dynamics.

Revolutionary design that is clearly different from traditional saloons' Exterior that is elegant around a comfortable interior. Dynamic bodylines that suggest precise and stable handling. The exterior is elegant and dynamic. Suzuki designers avoided the frills and low height of many saloons, and took on the challenge of creating a revolutionary design. Praised with the Swift, Suzuki's New Design concept, which is influenced by the latest European design trends, is also reflected in the SX4 Sedan. A trapezium form, wide treads and large wheels stress the solid structure of the body whilst a strong wedge shape and kicked up waistline project an active lifestyle look.
