Toyota GR Corolla vs Hyundai I20

What's the difference?

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

The i20 N hatch is so much fun, and not in a special occasion kind of way. It’s an affordable, compact performance car that’ll put a smile on your face no matter where or when you drive it. The Fiesta ST and Polo GTI have a worthy new playmate. I love it!

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’.

Hyundai’s current WRC challenger may be a coupe but this angry little five-door hatch absolutely looks the part.

We’re assured the N is the only current-generation i20 we’ll see in the Aussie market, and it runs with a relatively low (101mm) ground clearance, a grille pattern inspired by a chequered flag, black mirror shells, and menacing, angular LED headlights.

The ‘Satin Grey’ 18-inch alloys are unique to this car, as are the side skirts, raised rear spoiler, darkened LED tail-lights, a ‘sort-of’ diffuser under the rear bumper and a single fat exhaust exiting on the right-hand side.

There are three standard paint options - ‘Polar White’, ‘Sleek Silver’, and N’s signature shade of ‘Performance Blue’ (as per our test car) as well as two premium shades - ‘Dragon Red’, and ‘Phantom Black’ (+$495). A contrasting Phantom Black roof adds $1000.

Inside, the N-branded sports seats, trimmed in black cloth, featuring integrated headrests and blue contrast stitching, are unique to the i20 N. There’s a leather-trimmed sports steering wheel, handbrake lever and gear knob, as well as metal finishers on the pedals.

The 10.25-inch digital instrument cluster and same-sized multimedia screen look slick, and ambient lighting heightens the hi-tech mood.

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.

Although it’s just 4.1m long, the i20N is impressively space efficient with decent room up front and a surprising amount of head and legroom in the back.

Sitting behind the driver's seat, set for my 183cm position, I had plenty of head and legroom, although, understandably, three people across the back will need to be kids or understanding adults, on a short journey.

And there are plenty of storage and power options, including the wireless device charge pad in front of the gear lever, which doubles as an oddments tray when not in use, two cupholders in the front centre console, door bins with room for large bottles, a modest glove box and a lidded cubby/armrest between the front seats.

No armrest or air vents in the back, but there are map pockets on the front seat backs, and again, bins in the doors with room for bottles

There is a media USB-A socket and another for charging, as well as a 12V outlet in the front, and another USB-A power socket in the back. Hyundai suggests the latter could be handy for powering track day cameras. Great idea!

Boot space is impressive for such a compact hatch. With the rear seats upright there’s 310 litres (VDA) available. Fold the 60/40 split-folding rear backrest and no less than 1123 litres opens up.

A dual-height floor can be flat for long stuff, or deep for tall stuff, there are bag hooks provided, four tie down anchors, and a luggage net included. The spare is a space saver.

At $32,490, before on-road costs, the i20 N is to all intents and purposes the same price as Ford’s Fiesta ST ($32,290), and the VW Polo GTI ($32,890).

It’s offered in one spec only, and aside from the standard safety and performance tech, this new hot Hunday boasts a solid standard features list, including: climate control, LED headlights, tail-lights, daytime running lights and fog lights, 18-inch alloys, Bose audio with Apple CarPlay/Android Auto and digital radio, cruise control, nav (with live traffic updates), rear privacy glass, keyless entry and start (as well as remote start), sports front seats, the leather-trimmed sports steering wheel, handbrake lever and gear knob, alloy-faced pedals, auto rain-sensing wipers, power-folding exterior mirrors, plus 15W Qi wireless smartphone charging.

There’s more, like the 10.25-inch ‘N Supervision’ digital instrument cluster, plus a same-size multimedia touchscreen in the centre of the dash, a track maps feature (Sydney Motorsport Park is already in there), as well as an acceleration timer, g-force meter, plus power, engine temperature, turbo boost, brake pressure and throttle gauges. 

You get the idea, and it goes toe-to-toe with the Fiesta ST and Polo GTI.

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 i20 N is powered by a turbo intercooled 1.6 litre four-cylinder petrol engine, driving the front wheels via a six-speed manual gearbox and Torsen-type mechanical limited slip differential.

The all-alloy (G4FP) engine features high-pressure direct-injection and an overboost function, producing 150kW from 5500-6000rpm, and 275Nm from 1750-4500rpm (rising to 304Nm on overboost at max throttle from 2000-4000rpm).

And the engine’s mechanical ‘Continuously Variable Valve Duration’ set-up is something of a breakthrough. In fact, Hyundai claims it as a world’s first for a production engine.

Not timing, not lift, but variable duration of valve opening (managed independently of timing and lift), to strike the optimal balance between power and economy across the rev range.

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.

Hyundai’s official fuel economy figure for the i20 N, on the ADR 81/02 - urban, extra-urban cycle, is 6.9L/100km, the 1.6-litre four emitting 157g/km of C02 in the process.

Stop/start is standard, and we saw a dash-indicated average of 7.1L/100km over several hundred km of city, B-road and freeway running on the occasionally ‘spirited’  launch drive.

You’ll need 40 litres of ‘standard’ 91 RON unleaded to brim the tank, which translates to a range of 580km using the official figure and 563 kays using our launch test drive number.

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.

Unusually for a manual car, the i20 N features a launch control system (with an adjustable rpm setting), which we found fiddly to get working, but with or without it, Hyundai claims a snappy 0-100km/h time of 6.7sec.

And it’s such a pleasure to steer a car with a slick-shifting manual gearbox. The six-speed unit features a rev-matching function accessed via the press of a racy red button on the steering wheel. 

Buf for those who prefer an old-school, double-shuffle, heal-and-toe tap dance across the pedals, the relationship between the brake and accelerator is perfect. 

And if you’re keen on Walter Rohrl-style left-foot braking, to help steady the car or steer it in fast cornering, the ESC is switchable through to Sport mode or completely off, allowing fuss-free simultaneous brake and throttle application.

There’s even a shift-timing indicator near the top of the instrument cluster, with colour bars closing in on each other as the tacho needle pushes towards the rev limiter. Fun.

Engine and exhaust noise is a combination of a raspy induction note and adjustable crackle and pop out the back, courtesy of a mechanical flap in the exhaust system, adjustable through three settings in N mode.

Traditionalists may not be thrilled by the addition of in-cabin synthetic enhancement of all of the above, but the net effect is thoroughly enjoyable.

It’s worth remembering in this context N stands for Namyang, Hyundai’s sprawling proving ground south of Seoul where the car was developed, and the Nürburgring where this go-fast i20 was fine-tuned.

The body has been specifically reinforced at 12 key points, along with additional welds, and “bolt-in underbody structures” to make the i20 N stiffer and more responsive.

The strut front, coupled (dual) torsion beam rear suspension has also been set up with increased (neg) camber and a revised anti-roll bar at the front, as well as specific springs, shocks and bushings.

A compact, mechanical LSD is added to the mix, and grippy 215/40 x 18 Pirelli P-Zero rubber was produced specifically for the car and is stamped ‘HN’ for Hyundai N. Impressive.

The end result is outstanding. Low-speed ride is firm, with suburban bumps and lumps making their presence felt, but that’s what you’re signing on for in a hot hatch at this price point.

This car feels balanced and well buttoned down. Power delivery is agreeably linear and at a fraction over 1.2 tonnes the i20 N is light, responsive and nimble. Mid-range urge is strong.

Steering feel is good, with assistance from a column-mounted motor taking nothing away from an intimate connection with the front tyres.

The sports front seats proved grippy and comfortable over long stints behind the wheel, and playing with the multiple N drive modes tweaking the engine, ESC, exhaust, and steering just adds to the involvement. There are twin N switches on the wheel for quick access to custom set-ups.   

And that Torsen LSD is brilliant. I tried my best to provoke a spinning inside front wheel on the exit of tight corners, but the i20 N just puts its power down without so much as a chirp, as it rockets towards the next bend.

The brakes are 320mm vented at the front and 262mm solid at the rear. Calipers are single piston, but they’ve been beefed up and fitted with high-friction pads. The master cylinder is bigger than the standard i20 and the front rotors are cooled by lower control arm mounted air guides blowing through vented knuckles.

The launch i20 N fleet of around half a dozen cars copped an hours long hot lap pounding at Wakefield Park Raceway, near Goulburn NSW without drama. They’re well up to the task. 

One niggle is a large turning circle. The data sheet says 10.5m but it feels like the car is carving a wide arc in U-turns or three-point turns.

A 2580mm wheelbase between the bumpers of a 4075mm car is substantial, and the steering’s relatively low gearing (2.2 turns lock-to-lock) no doubt has a lot to do with it. The price you pay for quick turn-in.

Although it hasn’t been assessed by ANCAP or Euro NCAP, the headline on active safety tech in the i20N is the inclusion of ‘Forward Collision-Avoidance Assist’, which is Hyundai-speak for AEB (city and urban speed with pedestrian detection).

And from there it’s assist city, with ‘Lane Keeping Assist’, ‘Lane Following Assist’, ‘High Beam Assist’, and ‘Intelligent Speed Limit Assist.’

Followed by all the warnings: ‘Blind Spot Collision Warning’, ‘Rear Cross-Traffic Collision Warning’, ‘Driver Attention Warning’, and ‘Parking Distance Warning’ (front and rear).

The i20 N also features a tyre pressure monitoring system and a reversing camera. But if, despite all that, a crash is unavoidable there are six airbags on-board - driver and front passenger front and side (thorax), and side curtain - as well as three top tether points and two ISOFIX locations across the back row for child seats.

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.

Hyundai covers the i20 N with a five year/unlimited km warranty, and the ‘iCare’ program includes a ‘Lifetime Service Plan’, as well as 12 months 24/7 roadside assist and an annual sat nav map update (the latter two renewed free-of-charge each year, up to 10 years, if the car is serviced at an authorised Hyundai dealer).

Maintenance is scheduled every 12-months/10,000km (whichever comes first) and there’s a pre-paid option which means you can lock in prices and/or fold service costs into your finance package.

Owners also have access to the ‘myHyundai’ online portal providing details on the car’s operation and features as well special offers and customer support.

Service for the i20 N will set you back $309 for each of the first five years, which is competitive for a hot hatch in this part of the market.
