Kia K4 in Australia: The Cerato Replacement Explained

The Cerato nameplate ended after more than two decades in Australia, replaced by the K4. If you own a Cerato, or if you are comparing small cars such as the Mazda3, Toyota Corolla and Hyundai i30, here is what changed and who the K4 suits.

Based on published specifications and reports; not our road test. Prices are before on-road costs and have changed since launch.

The short version

Body styles: sedan (2025) and hatchback (added for 2026).
Engines: a 2.0-litre petrol in lower grades and a 1.6-litre turbo petrol in the GT-Line.
Price: roughly $32,100 to $43,800 now, compared with $30,590 to $42,990 at launch.
Boot: about 508 litres in the sedan and 438 litres in the hatch.
Hybrid: none confirmed for Australia.

Body styles and grades

The K4 launched as a sedan in 2025, and a hatchback was added for the 2026 model year. Pricing and equipment are the same for both. The range includes S, Sport, Sport+ and GT-Line grades, with five grades reported in total. Current published pricing runs from about $32,100 to $43,800, compared with launch pricing of $30,590 to $42,990.

The jump from the cheapest to the most expensive K4 is more than $11,000. Decide early which features you actually want, because the top grade costs about as much as an entry-level SUV.

Engines

2.0-litre petrol: originally 112 kW and 192 Nm with a six-speed automatic and a claimed 7.4 L/100 km. A later, more efficient 2.0-litre with a CVT trades a little power for lower fuel use.
1.6-litre turbo petrol (GT-Line only): about 142 kW and 264 Nm, with an eight-speed automatic and a claimed 6.7 L/100 km.

Kia Australia has said it has lobbied for a hybrid K4, but one has not been confirmed.

A fuel-use example

Using the launch claims and an illustrative $2.00 per litre over 15,000 km a year:

2.0L at 7.4 L/100 km: about 1,110 litres, or roughly $2,220 a year.
1.6T at 6.7 L/100 km: about 1,005 litres, or roughly $2,010 a year.

The turbo GT-Line claims lower consumption and more power, but it also costs thousands more to buy, so the fuel saving of about $210 a year doesn’t pay for the upgrade. Choose the GT-Line for its performance and equipment, not for fuel savings. The updated 2.0-litre’s own claim should be checked on Kia’s current specification sheet.

Boot and practicality

The sedan’s boot is about 508 litres, which is large for the class. The hatch has about 438 litres with the rear seats up, and the hatch’s wide opening makes it easier to load bulky items. All hatch variants have a 47-litre tank. If you carry pushchairs or sports gear, test both body styles with your real items.

Features and driving feel

Kia Australia’s engineers developed a local suspension and steering tune for the K4, which reviewers have commented on positively. GT-Line adds sportier styling and extra equipment. Because “driving feel” is subjective, test it on roads you know, including rough surfaces.

K4 vs its rivals

	K4	Mazda3	Toyota Corolla	Hyundai i30 sedan
Launch price range (sedan)	$30,590 to $42,990	$30,470 to $42,470	$32,320 to $40,260	$29,000 to $41,500

The K4 launched at a higher price than the Cerato it replaced, by roughly $4,000 to $6,700 depending on the grade. Rivals have also changed prices since, so compare current drive-away quotes. Key points to weigh:

Warranty: Kia’s seven-year, unlimited-kilometre cover. See our warranty guide.
Fuel economy: a hybrid Corolla may use less fuel.
Space: the K4 sedan’s boot is generous.
Equipment per dollar: compare the specific grade you would buy.

Coming from a Cerato?

Expect a higher price, a new name and updated technology. If you are trading in a Cerato, get an independent valuation first. See how to buy a new Kia for how to compare quotes and trade-ins.

Who it suits

Commuters and small families who want a roomy sedan or hatch with a long warranty.
Buyers who want sporty looks without an SUV.
Drivers moving down from a larger car who want space without bulk.

Who might look elsewhere

If fuel economy is your priority, a hybrid small car or the upcoming Seltos hybrid may save more fuel, though a compact SUV costs more.

Test-drive checklist

Drive the 2.0L and the 1.6T back to back if you can.
Compare sedan and hatch loading with your gear.
Check rear-seat room for the tallest passenger.
Listen for road noise on coarse bitumen.
Ask for the drive-away price and the capped-price service schedule.

Frequently asked questions

Is the K4 the same as the Cerato? It replaces it, with a new name and updated design and technology. It is not a cosmetic update of the old car.

Is there a hybrid or electric K4? No hybrid has been confirmed for Australia.

Is the hatch more expensive than the sedan? Reports say pricing and equipment are the same.
