Kia Cerato vs Mazda 3 Close

A Comprehensive Cars Comparison by Cars4us

The Kia Cerato and Mazda 3 have long been two popular choices for Australian small-car buyers, but they approach the segment from noticeably different directions. The Cerato focuses heavily on space, equipment and value, while the Mazda 3 brings a more premium cabin and a greater emphasis on design and driving refinement. Both have also been offered in hatch and sedan body styles, giving used-car buyers plenty of choice. For this Kia Cerato vs Mazda 3 comparison, we’re focusing on the Cerato Sport and Mazda 3 G20 to see which makes the stronger everyday small car.

Powertrain & Performance

Kia Cerato Sport

7/10

The Cerato Sport uses a 2.0-litre naturally aspirated four-cylinder petrol engine producing 112kW and 192Nm, paired with a six-speed automatic transmission.
It is a straightforward combination that works well for everyday driving, offering predictable performance around town and enough power for highway driving without trying to be particularly sporty.

Mazda 3 G20

7.5/10

The Mazda 3 G20 also uses a 2.0-litre naturally aspirated petrol four-cylinder, producing 114kW and 200Nm through a six-speed automatic.
The outputs are very close to the Cerato, but the Mazda distinguishes itself through the driving experience. Its steering, chassis balance and overall refinement give it a slightly more polished feel from behind the wheel.
Verdict: Performance is closely matched on paper, but the Mazda 3 provides the more refined and engaging driving experience.

Interior Comfort & Features

Kia Cerato Sport

7/10

The Cerato Sport takes a practical approach to its interior, with a straightforward layout and plenty of useful everyday technology.
A 10.25-inch touchscreen provides Apple CarPlay and Android Auto connectivity, while the cabin offers good storage and easy-to-use controls. It may not feel particularly luxurious, but it is functional and well suited to everyday use.

Mazda 3 G20

8/10

The Mazda 3 takes a noticeably more premium approach. Its dashboard design, materials and presentation give the cabin an upmarket feel compared with many small cars.
Its infotainment system is operated primarily through a rotary controller rather than relying entirely on touchscreen inputs. It can take some adjustment, but the overall presentation is clean and sophisticated.
Verdict: The Cerato offers plenty of useful technology, but the Mazda 3 has the more premium and polished cabin.

Space & Practicality

Kia Cerato Sport

8.5/10

Practicality is one of the Cerato’s biggest strengths.
The hatch offers 428 litres of luggage capacity, while the sedan increases that to a substantial 502 litres. That makes either body style a useful option for buyers carrying shopping, luggage, prams or other everyday cargo.
Passenger accommodation is also generous for the class.

Mazda 3 G20

7/10

The Mazda 3 trades some outright practicality for its more design-focused shape.
The hatch offers 295 litres of luggage capacity, making it noticeably smaller than the Cerato hatch. The sedan improves considerably with 444 litres, although it still falls short of the Cerato sedan.
Rear passenger space can also feel more enclosed, particularly in the hatch.
Verdict: The Cerato is the clear practicality winner, offering more luggage space in both hatch and sedan form.

Fuel Economy

Kia Cerato Sport

7/10

The Cerato Sport’s 2.0-litre petrol engine has claimed combined fuel consumption of around 7.4L/100km.
It is reasonable for a naturally aspirated small car, although buyers covering substantial kilometres may notice the difference compared with more economical alternatives.

Mazda 3 G20

8/10

The Mazda 3 G20 has a claimed combined consumption figure of around 5.9L/100km, depending on body style and specification.
That gives it a worthwhile efficiency advantage over the Cerato, particularly for commuters and drivers covering higher annual kilometres.
Verdict: The Mazda 3 is the more fuel-efficient choice and should cost less to fuel over longer-term ownership.

Safety & Driver Assistance

Kia Cerato Sport

7.5/10

Safety ratings for the Cerato vary depending on the specific grade and equipment fitted.
The Cerato Sport received a 4-star ANCAP rating under the assessment applicable to the model, while higher grades equipped with a more advanced autonomous emergency braking system achieved 5 stars.
That makes it important for used buyers to check the exact grade and safety specification of the vehicle they are considering.

Mazda 3 G20

8.5/10

The Mazda 3 achieved a 5-star ANCAP safety rating when assessed in 2019.
Its safety package includes a broad range of active driver-assistance technology, helping make it a strong choice for buyers who place a high priority on safety equipment.
Verdict: Against the Cerato Sport specifically, the Mazda 3 holds the advantage with its 5-star ANCAP rating.

Price & Value

Kia Cerato Sport

8.5/10

Value has always been central to the Cerato’s appeal.
The Sport combines a practical cabin, large boot and generous standard equipment with Kia’s seven-year new-car warranty when originally sold, with any remaining balance potentially adding appeal to later used examples.
That combination can make the Cerato particularly attractive for buyers prioritising practicality and equipment for their budget.

Mazda 3 G20

7.5/10

The Mazda 3 typically positions itself as the more premium alternative, with its cabin quality, exterior design and driving experience helping justify that positioning.
For used buyers, it can represent an opportunity to access that more upmarket experience without moving into a prestige badge.
Verdict: The Mazda feels more premium, but the Cerato makes the stronger value argument through its space, equipment and ownership proposition.

Our Verdict

Kia Cerato 7.6/10

Mazda 3 7.8/10

Final Verdict: Which Should You Choose?

Choose the Mazda 3 G20 if you prioritise cabin quality, driving refinement, fuel efficiency and safety. It feels like the more premium small car and is particularly appealing for buyers who value how their car drives and feels.

Choose the Kia Cerato Sport if practicality and value come first. Its larger boot, useful standard technology and spacious everyday layout make it an easy small car to live with.

Ultimately, the Kia Cerato vs Mazda 3 decision comes down to what matters most to you. The Mazda 3 offers greater refinement, while the Cerato gives you more space and practicality for your money.
