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.
Configure the SThe Kia K4 S Sedan is the entry grade of Kia Australia's Cerato successor in four-door form. It runs a 2.0-litre naturally aspirated four-cylinder making 110kW and 180Nm through a six-speed automatic, sipping 6.0L/100km combined. The sedan body adds a generous 508-litre boot and a longer 4710mm body versus the hatch, making it the pick for buyers who want extra luggage room. The base S without the optional Safety Pack carries a five-star ANCAP rating and six airbags.
Configure the S SedanThe 2026 Kia K4 Sport is $36,690 RRP, which is the recommended retail price, before on-road costs. For that you get a five-seat petrol hatchback with a CVT, driving the front wheels. Fuel use is 6.1L/100km on the combined cycle from a 47-litre fuel tank, and the boot holds 438 litres with the seats up. Braked towing is 1,100kg, and unbraked is 610kg, so think small box trailer rather than anything heavy. It suits someone after a practical everyday hatch with a long warranty behind it.
Configure the SportThe Kia K4 Sport Sedan steps up from the base S with 17-inch alloys and added equipment while keeping the efficient 2.0-litre petrol four and six-speed automatic (110kW/180Nm, 6.0L/100km combined). In sedan form it offers a 508-litre boot and a 4710mm body, giving it more luggage space than the hatch. The Sport and all grades above it carry a five-star ANCAP rating with eight airbags.
Configure the Sport SedanThere's 438 litres of boot space with the seats up in the 2026 Kia K4 Sport+, a five-seat petrol hatchback running a CVT and driving the front wheels. It's $39,090 RRP, which is the recommended retail price before on-road costs. Fuel use is 6.1L/100km on the combined cycle from a 47-litre fuel tank, and it'll tow 1,100kg braked. The claimed 0-100km/h time is 9.8 seconds, so it isn't built for quick sprints. It suits someone after a practical hatch with a long warranty for everyday commuting and the odd small trailer.
Configure the Sport+The Kia K4 Sport+ Sedan is the top non-turbo grade, adding artificial leather seats, an auto-dimming mirror and other comfort kit while retaining the 2.0-litre petrol four and six-speed automatic (110kW/180Nm, 6.0L/100km combined). The sedan body provides a 508-litre boot and a 4710mm overall length. It is a five-star ANCAP vehicle with eight airbags.
Configure the Sport+ SedanThe 2026 Kia K4 GT-Line is a five-seat petrol hatchback for people who want a practical everyday car that can handle the commute, the shopping and the odd weekend away. It's $43,790 RRP, which is the recommended retail price, before on-road costs. Fuel use is 7.4L/100km on the combined cycle, and the boot holds 438 litres with the seats up. It'll also tow 1,100kg braked. With a 47-litre fuel tank and front-wheel drive, it suits a small family or a couple who mostly stick to sealed roads and want room for luggage without stepping up to an SUV.
Configure the GT-LineThe Kia K4 GT-Line Sedan is the flagship four-door, swapping in a 1.6-litre turbocharged four producing 142kW and 265Nm through an eight-speed automatic. It pairs sportier styling, 18-inch alloys and uprated brakes with the sedan's roomy 508-litre boot and 4710mm body. Combined fuel use is 6.7L/100km and it carries a five-star ANCAP rating with eight airbags.
