Hyundai I30 vs Toyota GR Corolla

What's the difference?

The updated Hyundai i30 N Line doesn’t look like or perform like a base model.

You really do get bang for your buck here with its features. It’s a good-looking hatch that’s fun to drive in the city or open road and while the multimedia system is basic and occupants will be squished in the rear row, everything else is a big plus.

The GR Corolla had a lot to live up to before, given the likes of the GR Yaris and GR86 fit their briefs so well.

Now, with a little more daily useability and a little more performance, the GR Corolla is even better at both sides of its Jekyl and Hyde personality.

The design memo seems to be to make the i30 N Line look sportier and more purposeful.

They've nailed the design. The i30 is a good-looking hatch that looks like it has European styling.

The reshaped grille features new air intake vents, and stylish V-shaped daytime running lights. The rest of the body looks sharply dressed with new side skirts, reshaped bumper, black side mirrors, dual exhausts and 18-inch alloy wheels.

The cabin has been refreshed with a black headliner, upgraded leather and suede upholstery with contrasting red stitching and an N Line steering wheel and leather gear shifter.

The dashboard features new materials and additional soft touchpoints that make the interior feel like it's not a base model at all.

The Corolla already looks more sporting than most hatchbacks even before the GR treatment, but a few tweaks up front, some wider wheel arches and a third exhaust exit at the back have this thing looking almost ready for a rallycross.

The only downside to that is the changes are relatively minor from some angles. If you weren’t aware of the GR version, you'd need to see the GR Corolla from the front or spot that exhaust to know something was up.

The update has, however, ushered in a change at the front bumper, where the air intakes have been adjusted for improved airflow “to the radiator, intercooler, brake ducts, sub radiator and automatic transmission fluid cooler”

In part, this was necessary to help cool the new automatic gearbox, though it does generally help with overall cooling.

While the GR Corolla looks the part, there’s more function to it. The air that passes in through the side intakes at the front is vented to a duct in the wheel arch that also cools the brakes.

It’s the same as the GR Yaris sibling in terms of the philosophy behind aerodynamics and cooling in many ways, though much of the Yaris is bespoke, where on the Corolla, parts have been attached to the standard body.

Like the outside, the inside of the GR Corolla is mostly the same bones as its non-hot-hatch relatives, but the aforementioned sports seats, leather trim and aluminium pedals are all fairly strong hints this isn’t quite ‘hire car spec’.

Like most hatches, the front row of the i30 benefits the most when it comes to leg- and headroom. Taller passengers will be most comfortable up front as the rear row doesn't offer all that much legroom. It's squishy behind my driving position and I'm only 168cm tall!

Access however is decent for both rows because of the wide door apertures, but it's a low car to get in and out of because of the 140mm ground clearance. Expect a couple of grunts after a gym session.

The seats in both rows are fairly well-padded and offer the most comfort on shorter journeys. Even with the new powered lumbar support on the drivers seat, fatigue can set in quickly on a longer trip.

Individual storage is excellent throughout the car with a large glovebox that can hold a thick manual, middle console, phone tray, four cupholders, a drink bottle holder in each door, two net map pockets and even a sunglasses holder!

Other than the Kia Cerato, the i30 has one of the largest boots compared to its rivals, at 395L, and it’s enough for road trips and a decent grocery haul. The taller boot lip means you can stack items too but you don’t get a spare wheel in this model, just a tyre mobility kit. The base model also doesn’t get a powered tailgate, but the lid is not heavy at all to operate.

The new digital instrument cluster looks great but the multimedia system is basic and there’s no satellite navigation, so you're reliant on the phone mirroring apps but these maintain a strong connection. The radio is a hit or miss but that’s typical for the grade level.

Charging options are great for a base model with a single USB-A port, three USB-C ports and 12-volt sockets, and a wireless charging pad to choose from.

As far as hatchbacks to build a daily-useable hot hatch upon go, the Corolla is a relatively solid starting point in terms of ergonomics.

Physical buttons and controls for things like climate are within reach for most functions of the car, though the multimedia touchscreen itself isn’t the most up-to-date.

The seats are comfortable but hold you firmly in place, and the steering wheel, pedals, and shifter are all in the correct positions for engaging driving - particularly important in the manual version.

The storage space is where the GR Corolla disappoints a little. There’s door card space for a water bottle, cupholders, the wireless device charger, but not really anywhere for larger items.

Behind the front row, adults will find themselves a little cramped in terms of kneeroom, while dark interior materials make the second row feel poorly lit.

Further back in the Corolla is the 213-litre boot, which is pretty small even for a hatchback, although Toyota lists a maximum 503 litres with the seats folded down.

Under the boot floor is a tyre repair kit, rather than a spare tyre. Keep that in mind if undertaking a road trip.

The 2025 Toyota GR Corolla comes in just one grade now, the highly-speced GTS, which starts from $67,990 plus on-road costs for the six-speed manual, but it's now available with an eight-speed automatic for $70,490.

Sounds like a lot for a Corolla, and it’s a little more than the $64,190 asking price the GTS manual wore before, but compare it to the highly-regarded Honda Civic Type R ($74,100) or the do-it-all VW Golf R ($70,590) and it lines up.

While the GTS has plenty of features for the price, they’re not all focused on the comfort of the interior.

For example, the synthetic leather and suede sports seats are manually adjustable, even though they are heated.

The 8.0-inch multimedia touchscreen is similar to that in the standard Corolla, too, plus dual-zone climate, USB-C ports, the wireless phone charger and JBL Audio system are all expected features of a hatchback at more than $60,000.

The GR Corolla does however gain heating for the leather-wrapped sports steering wheel, plus leather trim for the parking brake and shifter too. It also scores aluminium pedals.

There’s a lot more under the skin when it comes to the GR, some of which is visible via controls in the cabin, but we’ll come to that.

The updated i30 N Line has a new mild-hybrid powertrain that features a 1.5-litre 7 four-cylinder turbo-petrol engine and combines to produce 117kW and 253Nm of torque. This new combo means it has higher outputs than its nearest rivals and you get three drive modes, including Sport which makes those outputs feel even more prevalent.

Like its rivals, the i30 N Line is a front-wheel-drive, but it has a seven-speed dual-clutch transmission which can sometimes feel like it's confused in stop/start traffic.

The GR Corolla’s 1.6-litre three-cylinder turbocharged petrol engine is now a little torquier than before, with outputs now 221kW (at 6500rpm) and 400Nm (between 3250 and 4600rpm) thanks to an extra 30Nm.

The G16E-GTS engine can now drive the Corolla’s four wheels through a choice of gearboxes, either the existing six-speed manual or an eight-speed torque converter automatic.

As well as the usual drive modes, Eco, Normal and Sport, the Corolla’s GR-Four all-wheel-drive system can split the torque to the front or rear wheels via its limited-slip diffs.

Normal, Track and Gravel modes can distribute drive either 60:40 front/rear in Normal, 53:47 in Gravel, or variably depending on conditions and need for acceleration in Track.

Toyota hasn't provided a 0-100km/h time for the 2025 GR Corolla in either variant, but the auto should knock it over in under five seconds, with the manual taking a little longer.

The new engine coasts in neutral when you’re not accelerating to improve efficiency and it works for that purpose as my real-world usage of 6.3L/100km isn't too far off the official combined fuel cycle figure of 5.6L.

Based on the official combined fuel cycle and 50L fuel tank, you should see a theoretical driving range of up to 893km, which is downright respectable.

Toyota’s claimed fuel consumption for the GR Corolla with a manual gearbox hasn't changed from the previous 8.4L/100km, which isn’t bad for a sports car.

With the auto, Toyota says it burns through the fuel faster at a rate of 9.5L/100km.

In either case, the Corolla’s 50-litre fuel tank needs to be filled with premium 98 RON petrol, and theoretically could provide more than 500km of driving if conditions and your driving style are both perfect for efficiency.

Chances are, however, you’ll feel the need to put your right foot down a little harder than they did during WLTP testing, if for no other reason than to hear the turbo flutter when you lift off.

The new powertrain is impressively punchy and you almost feel like you’re driving a hot hatch when you hit the open road because it’s effortless to keep up and overtake when necessary. 

The steering is firmer than what you’d expect and that makes the car feel heavier than what it is. Cornering is great – barely any roll – but the suspension is not finely tuned, especially for regional roads. But the overall feel is sporty, so it’s forgivable. 

At lower speeds, the cabin is delightfully quiet and although the exhausts are thrumming with noise, you don’t really hear it! It’s only once you get on the open road that the road noise creeps up but you can hold a convo without raising your voice, so that’s still good.

The i30 is pretty low to the ground and that makes it easy to scrape the bottom of it, especially when you have a full car load, so take ramps and bumps at a slight angle.

Hatches are always the best for parking because you can park ‘em anywhere! The i30 N Line has front and rear parking sensors and a decent reversing camera, so it’s extra easy.

The GR Corolla isn’t as engaging to drive as the GR Yaris, it’s not as honed as one particular rival, the Honda Civic Type R, and it’s not as ‘nice’ as the Golf R.

But the GR Corolla is still an excellent car to drive, and it’s better for its update. In fact, the two major gripes I had with the pre-facelift car have been addressed.

I was in a unique position to be able to compare the old and new versions of the GR Corolla as I drove a MY 2024 version a week prior to the media launch for the 2025 model.

The first and probably biggest issue I had was that the Corolla’s suspension seemed like it must have been rather stiff and the body bracing quite rigid for a car riding on 19-inch wheels to let that much road noise and that many harsh bumps into the cabin.

Though it wasn’t mentioned before the on-road drive loop, the car felt more compliant without sacrificing ability and seemed much more suited to daily duties.

Toyota’s product team confirmed there had been tweaks made to the rear suspension geometry and that I wasn’t just imagining it.

The second issue is more for the sake of passengers who may be less agreeable to the three-pot thrum resonating along the exhaust underfloor.

Toyota has solved this by putting a slight mute on the pipes in the Eco drive mode, so the car is now just ‘a bit’ lairy rather than full boy racer.

Generally, it’s hard not to compare the GR Corolla to the smaller (but original) GR hatch, the Yaris. Especially having driven them back-to-back at the media launch.

Without leaning too much on that, I will say that while the Yaris feels like a rally car that's been modified to be road-legal, the Corolla feels more like a road car that was tweaked for rallying.

The Corolla stops just short of being too ‘raw’ for everyday use in most aspects, but it’s still very capable when it comes to driving fast. 

Like its suspension, the steering feel is dialled in for feedback without being too rough, and allows you to corner accurately without feeling like you need to second-guess or adjust inputs.

When it comes to handling, it doesn’t feel like the Corolla is entirely leaning on the Yokohama Advan tyres for grip, as it feels tied-down and doesn’t pitch and roll through corners.

The duality of the GR Corolla is helped by its drive mode and differential settings and even on track can help you lean into your own driving style.

While the rear-biased 30:70 setting previously made for a slightly tail-happy hot hatch, the new variable Track setting does a fabulous job of keeping the drive where it needs to be, though it turns out it’s also rather handy for sliding the Corolla around a wet skid pan.

Another neat trick is the GR’s handbrake, same as the Yaris, which can disconnect the rear diff when engaged so you don’t need to dip the clutch pedal in the manual version when indulging in handbrake turns.

It will set you back to 2WD mode when the drivetrain overheats, however, or at least when its sensors suspect the drivetrain has overheated - something that only happened after a lot of handbrake turning and spinning wheels as the hatchback slid sideways.

The Corolla’s brakes are ventilated 356mm front and 297mm rear discs, and doesn't lose stopping power even after plenty of tight, twisting road driving where the brakes and the sticky Yokohama Advan tyres copped a workout.

The new auto transmission is also a delight. It's calm during normal driving but snappy with shifts in Sport mode and set to manual gear selection. It won’t really cooperate on a rapid drive of its own accord.

The only criticism of the auto gearbox (aside from being less engaging than the manual, but that’s your own choice) is that the shift paddles behind the wheel feel a little plasticky, but I’m nitpicking at this point.

The Corolla’s not lacking in safety kit, with a healthy list of passive and active features as well as a series of seven airbags and three ISOFIX points along the rear seats.

ANCAP tested the non-GR Corolla in 2018 and awarded it five stars, though that score is now outdated. It’s not clear if the car’s updated tech would manage five stars again, though the car is clearly structurally sound.

Aside from the usual expectations like auto emergency braking (AEB), a blind spot monitor, parking sensors front and rear plus a decent reversing camera, the GR Corolla also has rear cross-traffic alert and Toyota’s ‘Safety Sense’ suite of active kit.

That includes a pre-collision safety system with pedestrian detection and cyclist detection in daylight, active cruise, intersection assist, emergency steering assist, lane departure and lane-trace assist, road sign detection for speed limits and auto high beam.

Hyundai offers the i30 with a five-year/unlimited km warranty, which is a normal term for the class and you can pre-purchase three-, four- or five-years worth for servicing and the five-year option cost $1795, which is competitive. 

Servicing intervals are okay at every 12 months or 10,000km, whichever occurs first.

Toyota offers a five-year/unlimited kilometre warranty plus an extra two-year warranty on the GR Corolla’s engine and driveline.

There’s also a capped price on the first three years of servicing for the GR Corolla at $310 per service.

The downside to the servicing arrangement is that intervals are six months or 10,000km, whichever comes first. That's more regular than a usual schedule and it means potentially pricier servicing for the seventh visit onwards.
