Hyundai I30 vs Kia Cerato

What's the difference?

Big boots to fill? The Hyundai i30 Sedan N stomps its authority with charming confidence and admirable talent. It’s hard to believe one of the biggest challengers to the i30 N hatch comes from its oddly-styled booted cousin. It’s just as thrilling, immersive, enjoyable and easy.

Which means that, if you’re in the market for a performance hot-hatch, it’s time for the sedan version to step into the limelight and be on your shortlist. It’s another N superstar.

Kia has value and packaging on its side with the sleek and spunky Cerato GT sedan. There’s no shortage of standard gear, it comes with the latest multimedia and safety gear and the cabin and cargo area are spacious and practical.

The powertrain is a winner too. Which is why it’s such a shame that it’s let down so badly by the ride quality.

If you’re going to be driving on various road surfaces, or regularly driving long distance, check out the far more compliant Hyundai i30 N-Line instead.

But if you’ll only ever drive in urban areas – or enjoy the occasional back-road blast – and you can handle the firm ride, there’s still plenty to like about the Cerato GT.

Now, with hot hatches, more usually means less, with spoilers quite literally living up to their name by blighting an otherwise clean and attractive design. For some, anyway. Under the radar and all that.

But the attention-crazy (CN7) i30 Sedan – known otherwise as the seventh-generation Elantra pretty much most other places around the world – seems like the work of a protractor-brandishing origamian who would not down pencil and stop.

Which means that, in the N’s case, more might actually be more, because all the racy extras enhance the appearance of a very distinctively/divisively-designed sedan.

The blacked-out bumper treatment, red brake calipers, side skirts and handsome alloys draw the eyes away from the odd creases and angles that define the i30 Sedan.

The result is a striking four-door fastback that comes into its own. One might suspect the original drawings were of a slammed-down N, with the overtly sporty stuff removed for the necessary lesser grades that most people end up buying.

Which would be a case of less being less!

Anyway, let’s check out the interior.

When the fourth-gen Cerato sedan was revealed in US-market Kia Forte guise at the 2018 Detroit motor show, the design was praised for taking inspiration from the sleek Stinger performance sedan.

The facelift has arrived at just the right time to keep the Cerato fresh against the dominant Toyota Corolla, Mazda3 and new Volkswagen Golf.

The sharpened front-end styling features an eye-catching daytime running light signature and the headlights now connect with the redesigned, slimline Kia ‘tiger-nose’ grille in gloss black.

It’s a subtle, yet successful design refresh.

Inside, the Cerato is starting to look its age against rivals like the Golf and Mazda3. Those GT themed additions definitely lift the ambience of the cabin, but the dash layout feels a bit generic and the overall interior design is nothing flash. Especially when you consider the interior of some of Kia’s latest models, like the impressive Sportage medium SUV.

Germany's small hot-sedan rivals would struggle to match the i30 Sedan N’s sheer practicality.

Running on a newer-generation architecture also shared with the latest Hyundai Kona, the result is a substantially larger, longer and wider proposition than the 2017-vintage i30 N hatch.

Upshot? The driver and passenger have plenty of space to stretch out in, within a palpably more contemporary cabin than presented in the five-door version. It feels like a car from the next size and decade up.

Being the i30 flagship, the N Premium’s dashboard is also dressed up to look suitably upmarket, angled towards the driver and offering twin 10.25-inch screens, with N-specific configurable instrumentation right ahead of the driver. Blue-stitched leather trim and darker cabin elements also set a racier ambience.

Predictably, there’s a comprehensive performance monitor within the touchscreen with all sorts of vehicle and driving data, including a lap timer. Clever if distracting. You might also take note of the big red button under one of the steering-wheel spokes, cringingly labelled NGS for ‘N Grin Shift’.

It brings a modest 7.0kW power boost, lasting only 20 seconds. Great for instant overtaking oomph, presumably.

Speaking of fast driving, lowered sports seats provide sufficient bracing through tight corners and extra ceiling clearance for helmets, while feeling sumptuously supportive the rest of the time. They're quite terrific.

Beyond these, all the regular sensible features found in more-humdrum i30 Sedans – an excellent driving position, ample ventilation, decipherable controls and stacks of useful storage – are also present.

The same applies across the generous back seat area, which lacks nothing for expected amenities to help keep kids of all ages safe, comfy, hydrated, ventilated and connected, while the N’s slightly-smaller boot (down 10 litres over the regular i30 Sedan) is still large enough for most needs at 464L. Blame the chassis stiffness brace back there.

Meanwhile, a space-saver spare lives underneath the wide, flat floor.

Complaints? The longitudinal buttress that runs along the left side of the centre console by the front passenger seat can constrict knee movement. Driver rear vision is poor, while that sloping back-door aperture makes getting in and out a head-banging affair for taller or bouffant-wearing folk.

Otherwise, the i30 Sedan N boasts a well-resolved cabin.

As mentioned, the red stitching throughout, chunky steering wheel and sports seats are welcome additions to the GT cabin.

There are soft-touch materials on the top of the dash but hard plastics on the dash fascia. 

There’s no fully digital instrument cluster, but it has a 4.2-inch LCD display in the cluster showing fuel economy and the like. No complaints with the analogue dials and there’s a digital speedo if required.

The update ushered in Kia’s latest multimedia system to the Cerato and it’s a winner thanks to cool graphics, logical menus and its ease of use.

There’s quite a sizable central storage bin and glovebox, while the console houses a key slot, two sizeable cupholders and a second spot for devices adjacent to the charging pad.

The front sports seats look sexy, have excellent side and body bolstering and they’re firm, but comfortable.

A 600mL bottle will just fit into the doors, bit it’s tight.

Sitting behind my six-foot (182cm) frame in the rear, legroom is adequate but toe room is tight. My head was about an inch away from the headliner due to the sloping roofline. The rear seats are also firm.

The Cerato has lower rear air vents, one USB-C port, a map pocket on the passenger side, a central rear armrest with two cupholders, and bottles slot into the doors easier than they do up front.

Kia offers a temporary spare wheel housed under the boot floor. The boot is long, offering an impressive 502 litres (VDA) of cargo space, which is more than other small sedans like the Subaru Impreza (460L VDA) and the Hyundai i30 (474L VDA).

Lower the rear 60/40 seats via the levers in the boot and that space increases further, but they don’t fold completely flat.

The GT is priced at $35,290 before on-road costs regardless of whether you opt for the four-door sedan (as tested here) or the five-door hatchback, though be aware that Kia Australia regularly runs drive-away pricing campaigns.

There’s not a lot of competition in the warmed-up small car market these days. A number of carmakers have slimmed down their small-car line-ups in the face of falling sales.

Kia’s closest rival is also its mechanical sibling, the Hyundai i30 N-Line sedan and hatch. The Hyundai is cheaper by more than $2500, but the more generously equipped i30 N-Line Premium sedan is a little over $2000 more expensive than the Cerato GT.

The Mazda3 GT sedan and hatch could also be considered a rival and pricing is about on par with the Kia.

Other lower grades in the Cerato range run from $25,490 to $30,640 (MSRP).

The GT benefits from the more premium powertrain offering in the Cerato line-up – the 1.6-litre turbocharged four-cylinder engine shared with the i30 N-Line and the recently discontinued Veloster Turbo.

The GT bodykit adds sporty styling flourishes like a black front and rear diffuser, boot spoiler, dual exhaust, black external mirror caps, red highlights and 18-inch GT alloy wheels. 

This theme carries through to the cabin too with features like alloy sports pedals, flat-bottom perforated leather sports steering wheel and leather-appointed seats with red stitching and embossed GT logo.

As the range flagship, the GT also has the most standard equipment. It comes with a sunroof, eight-way power driver’s seat, wireless device charging, an eight-speaker JBL premium sound system, heated and ventilated front seats and dual-zone climate control air conditioning.

The only option fitted to the test car was Snow White Pearl premium paint for $520.

Make no mistake. Under the bonnet beats the absolute heart and soul of the Hyundai i30 Sedan N.

The engine carries over from before – a 1998cc 2.0-litre turbocharged four-cylinder direct-injection unit, making 206kW of power at 6000rpm and 392Nm of torque between just 2100 and 4700rpm.

Tipping the scales at 1475kg, the resulting power-to-weight ratio is an impressive 140kW/tonne. And, don’t forget, pressing the N Grin Shift unleashes an extra bit of power, bumping the total up to 213kW for a 20-second burst.

The 0-100km/h sprint time takes 5.3 seconds, on the way to a 250km/h top speed.

Refreshingly, traditionalists can still choose a six-speed manual (albeit with a rev-matching function), or eight-speed wet-type DCT dual-clutch auto transmission, and both drive the front wheels via an electro-mechanical limited-slip differential.

While all other Cerato grades use a 112kW/192Nm 2.0-litre naturally aspirated petrol engine, the GT benefits from a spicier powertrain.

Under the bonnet is the Hyundai Group 1.6-litre T-GDI four-cylinder turbocharged petrol engine delivering 150kW of power at 6000rpm and 265Nm of torque at 1500-4500rpm. This is the same tune as the Hyundai i30 N-Line.

This is paired with a seven-speed dual-clutch automatic transmission that drives the front wheels. Lower grades use a six-speed torque converter auto. Kia dropped the manual from the S and Sport grades as part of the update.

The GT differs from the rest of the Cerato range as it has multi-link rear suspension, instead of a torsion beam setup. Both the suspension and steering have been tuned for dynamic driving. More on that later.

The i30 N DCT’s official combined average consumption is 8.3 litres per 100km, for a carbon dioxide emissions rating of 194g/km.

Around town, that consumption figure shoots up to 11.8L, and drops to 6.3L outside of urban areas. Add 0.2L apiece for the less-efficient (but more-engaging) manual version.

Filling the 47L tank, with 95 RON premium unleaded petrol, you could exceed 565km between refills on average.

With a combination of gentle highway schlepping and blasting through the hills around the fast Murray River-area rural roads, our trip computer indicated a commendable 10L/100km – given this car’s 250km/h performance.

According to Kia, the Cerato GT sedan uses 6.9 litres of fuel per 100km on the combined cycle. The GT hatch uses 0.1L less.

After a week of mixed driving in the Cerato GT, we recorded a combined fuel consumption figure of 9.0L/100km – a fair bit more than Kia’s claim.

The GT emits 157g/km of CO2 (official combined).

Out about the hilly roads around Albury/Wodonga, the i30 Sedan N feels in its absolute element. The mixture of long open straights and tight corners really show off Hyundai’s incredible chassis tuning capabilities.

i30 Sedan N improvements for 2024 include brakes with better cooling and resistance to fade, stronger engine mounts for improved agility, more insulation, reduced vibrations, upgraded steering components for even more-precise handling and tweaks to the stability control system for more-effective operation.

Suspension is by McPherson-style struts up front and a multi-link rear-end arrangement.

Aided by an active variable exhaust note (which is quite nicely applied), the 2.0-litre four-pot twin-scroll turbo has a deep set of lungs, providing a decent wad of torque as it revs out fast and freely to its 6000rpm red-line. As you might expect, this is deceptively rapid.

Whether driving the solid and well-oiled six-speed manual – surely one of the best in the business and truly a great thing – or super-slick eight-speed DCT, there’s a delightful amount of muscle and speed for the money.

We’re also fans of the steering’s poise and response, resulting in hunkered-down handling that belies this car’s substantial length and width, backed up by lots of feel and feedback.

Throw in delightfully strong and effective braking, and the i30 N is incredibly alert and agile for something so big.

The trade-off of all this athleticism is a consistently firm – though not harsh – ride, as well as some road and tyre-noise intrusion when cruising comfortably along the highway.

As an everyday commuting proposition, the i30 Sedan N is right on the money.

Out on the racetrack, however, it's like on something a little bit more illicit, for things really start coming alive, with the N’s polished chassis set up revealing a satisfyingly vivid bandwidth of capability.

In 'Normal' mode, the front end feels reassuringly planted with minimal understeer, while the rear possesses a playful lightness that allows for progressive back-end lift-off if desired.

The i30 is so exquisitely tuned and pliable it makes amateurs feel like professionals.

Select 'N' mode and the electronic limiters loosen, for proper oversteer fun if that’s your thing, controlled and reeled right back in by meaty, confidence-boosting steering, providing improbably fluent handling for a sedan this size.

Slicing through tight bends and long arcs alike, the Hyundai’s sheer dynamic precision, consistency and discipline are deeply impressive. And intoxicating. We didn’t want to stop.

It may not look like a hot hatch in the prime of its life, but the i30 Sedan N sure behaves like one. And all for just $52K. Cheers, Hyundai!

The 1.6-litre turbo engine is a ripper and it’s been put to good use in Hyundai’s i30 N-Line and Veloster Turbo.

It’s just as willing and responsive under the bonnet of the Cerato GT, but they each perform quite differently.

Accelerating from a standing start, there’s mild turbo lag in the Cerato, and some torque steer when accelerating hard.

Once up and running it’s quick, and the seven-speed dual clutch snaps through the gears smoothly while still allowing it to rev freely.

It’s the type of powertrain that is utterly unbothered by things like steep ascents. The Cerato GT just keeps pushing on, without losing momentum.

The downside of that is that the engine is super noisy when pushed and the Kia just doesn’t have sufficient noise suppression materials to counter that. Because of this, it lacks the refinement of its i30 N-Line cousin and the Mazda3.

Steering is weighted on the heavier side but it’s direct and the car goes where you point it.

Like many Kia models, the Cerato GT benefits from an Australian-specific steering and suspension tune. Kia doesn’t have a full performance hot hatch to line up with the i30 N, but the engineers seem to have tuned the suspension to be just as capable as the full-fat i30 N.

That certainly aids dynamic driving in the Cerato GT. It hugs corners and grips the road, avoiding any skipping and with only a hint of body roll.

However, we think Kia’s engineers have made the damper settings too firm, because the Cerato GT’s ride is harsh in virtually all driving environments.

A new, freshly laid road surface in an urban area without any speed bumps was the only time the ride was comfortable during our week with the car.

It crashes over potholes and it’s loud and jarring when you unexpectedly encounter a sharp rut. There’s a bit of vibration through the steering wheel too.

This is disappointing, especially when you consider that the i30 N-Line has a much more supple ride and is the sort of warmed-up hatch or sedan you could easily live with day to day.

We briefly drove the i30 N hot hatch just before we got into the Cerato GT and even that has a more tolerable ride quality than the Kia.

The Cerato GT achieved a five-star ANCAP crash safety rating in 2019 and it applies to all Cerato variants built after June 2021, except the S and Sport which have four stars because the autonomous emergency braking system offered as standard in those grades can’t detect vulnerable road users like pedestrians and cyclists.

Standard safety for the GT includes auto emergency braking (AEB) with pedestrian and cyclist detection, forward collision warning, rear occupant alert, driver attention assist, rear cross-traffic alert with collision avoidance, blind spot detection and collision avoidance assist, adaptive cruise control, lane keep assist with lane follow assist steering, safe exit warning, front and rear parking sensors and a reversing camera.

At one point, the AEB kicked in pulling out of a parallel street parking spot because it detected a vehicle that had already driven past the car and was several metres ahead.

Kia’s lane keep assist system is generally impressive and functions without issue, but it pulls on the wheel a little. It’s not jolty like systems offered by some other brands.

When lane keep and follow assist are active, it can be fiddly to switch them both off. If you hold the steering wheel-mounted button down, the follow assist stays on but the lane keeping deactivates, so you just have to keep holding the button down until the lane and steering wheel icons in the digital display eventually disappear.

The i30 Sedan N brings a five-year/unlimited kilometre warranty, as well as one year of roadside assistance.

Service intervals are at 12-months or 10,000km (not at every 15,000km like the regular i30 Sedan), with service pricing published on Hyundai’s website.

Over the first five years, the standard scheduled cost is $1795, or an average of under $360 annually.

The Cerato, like all Kia models, is offered with a seven-year/unlimited kilometre warranty, and one-year free roadside assist which extends year by year if you service with Kia (up to eight years).

It also comes with a seven-year capped-price servicing plan that costs approximately $3234 over the seven-year period.

Servicing intervals for the Cerato GT are every year or 10,000km, whichever comes first.
