What is it?
The K4 is Kia's all-new small car, replacing the Cerato. It launched in Australia in late 2025 with the sedan, with the hatch (K4 5-Door) following in 1H 2026. Wider, longer, and riding on the longest wheelbase in the segment (2,720 mm), it delivers class-leading 964 mm rear legroom. Two petrol engines, no hybrid for Australia at launch. 2.0 MPI four with 112 kW on a CVT is the entry, 1.6 turbo with 142 kW on an 8-speed auto is the GT-Line flagship. FWD across the range, 7-year unlimited km warranty.
The lineup runs from S 2.0 (sedan) at $30,590 plus on-roads, through to GT-Line Turbo (sedan) at $40,990 plus on-roads. Warranty cover sits at 7 years, unlimited km.

Should you buy the K4?
Reasons to buy
- Longest wheelbase in the small-car segment at 2,720 mm, delivering class-leading 964 mm rear legroom and a 508 L sedan boot. Twin 12.3-inch curved display layout pulled from Kia's EV lineup.
- Warranty: 7 years, unlimited km.
- 508 L boot, segment-competitive cargo space.
Reasons to wait
- No hybrid powertrain for Australia at launch. Corolla and Civic walk past on running cost. Base S uses wired CarPlay and Android Auto, not wireless.
- You want a hybrid powertrain (Corolla Sedan Hybrid or Civic e:HEV), or you prefer a hatch body straight away (the K4 hatch follows the sedan in 1H 2026).
- Hatch arrives 1H 2026, sedan first. ANCAP rating pending against the 2026 protocol. GT-Line Turbo is the pick if you can stretch, the base S 2.0 makes sense only on price.
- Top trim climbs to $40,990 plus on-roads.
