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.
