The 2026 Kia K4 S is a five-seat front-drive hatch for buyers who want a straightforward daily car with a long warranty. It uses a 2.0-litre four-cylinder petrol making 110kW and 180Nm through a CVT automatic, claiming 6.1L/100km combined and 143g/km on the ADR 81/02 cycle. Practical points in its favour: a 438-litre boot, a 5-star ANCAP rating with autonomous emergency braking standard, and seven years of warranty. Two things worth knowing before you compare it with a sedan K4: the hatch's boot is 438 litres against the sedan's 508, and the hatch's fuel figure is slightly higher than the sedan's because it is a different body, not a different tune. Braked towing is 1,100kg.
