The exterior design of the K4 features a sleek, fastback silhouette with a lower roofline and beltline than its predecessor. The overall design is more sporty than the outgoing Cerato too, incorporating Kia's 'Opposites United' design philosophy and its familiar Tiger Face front fascia.

The car has flush second-row door handles, black wheel arch cladding, and wheel sizes ranging from 16 to 18 inches depending on the trim.

Eight exterior colours are available including four new colours - Interstellar Grey, Fiery Red, Wave Blue and Honeydew. They join Clear White, Snow White Pearl, Steel Gray and Aurora Pearl Black, but only Clear White is available as a standard colour, all others are charged at a $600 premium.

Cloth seats are standard on the S and Sport trims, while artificial leather seats are available on the Sport+ and GT-Line trims. GT-Line vehicles gain embossed GT-Line details on seats, two-tone seats and a wide sliding sunroof

Rear seat passengers have access to twin USB-C ports, rear air vents and a storage cubby. Thanks to the increased dimensions of the K4 over the Cerato, rear legroom is increased by 56mm and space is increased for front row passengers who get greater head and shoulder room.

All trims also include a full complement of airbags, including a front Centre Side Airbag.

The inclusion of the Kia Connect system enables additional safety functions including emergency call and automatic collision notification.

A safety pack can be added to the base model K4 S to add a panoramic display with 12.3-inch instrument display and five-inch HVAC interface, plus dual zone climate control and additional AEB technology including junction turning and crossing, and direct/oncoming land change detection functionality.

The Sport, Sport+, and GT-Line variants also include Highway Driving Assist 2 (HDA 2), which combines adaptive cruise control and Lane Following Assist to keep the car centered in its lane, even through curves. HDA 2 also includes Lane Change Assist, which allows the K4 to autonomously change lanes under certain conditions.
