Hyundai Sonata vs Toyota GR Corolla

What's the difference?

The updated Sonata N Line looks beautifully modern from its new face to the refreshed cockpit, while remaining a ‘driver’s car’ with good dynamics, and a sporty engine. 

The Sonata isn’t an ideal family car, however. This is down to a lack of practicality. Although the cabin is fairly roomy, if that roofline wasn’t so coupe-like and cabin storage was better, and the boot had a large hatch opening, and the ride height was more elevated then it would be a great family car. Oh, I’ve just described an SUV.

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.

So, we’ve established that the Sonata N Line is a sedan and that means if you’re still reading this you are, a) A Sonata owner looking to trade the old one in for this new one, b) Driving another type of sedan such as a Toyota Camry or Volkswagen Passat and looking to update your trusty steed with one from Hyundai or c) Not in the market for an SUV.

Whatever the reason, sedans lend themselves to being sleek and sophisticated in their styling just by being lower to the ground than SUVs and generally longer than sports cars.

The Sonata N Line is long at 4.91m end-to-end. That’s only 8.0cm shorter than the gigantic Hyundai Palisade which has eight seats. I know… it bends the mind.

This new Sonata N Line looks even wider than the previous version, too, with that broad flat bonnet meeting the Seamless Horizon LED strip.

Fact is the Sonata N Line is 1.86m across - exactly the same as the previous version. Remind me never to wear a 'seamless horizon' T-shirt on days I’m feeling rotund. 

If you look closely at the photos you can see the hidden LED headlights flanking the large, dark and low-set grille.

The rear of the new Sonata looks so different from the previous version, too, with its boot lid spoiler and LED tail-lights. 

The menacing body kit comes with the N Line grade and accentuates the sporty nature of this car. It’s a good thing it has an engine to back up the looks, but more on that later.

Inside, the Sonata has been given the new 12.3-inch curved screens and a digital climate control display, while the steering wheel is new and adorned with the Hyundai 'Morse Code' badge (the letter H is four dots in Morse Code). It’s a premium and modern looking cockpit topped off with suede and leather leather N Line sports seats.

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’.

Sedans might be sleek and sophisticated but practicality is not typically their strength because their low height means passenger access isn’t as easy as it is with an SUV, but mainly because the cargo carrying ability is limited by the relatively small boot opening.

Still, the Sonata N Line does have a big 480-litre boot and cabin storage has been improved thanks to the gear shifter being relocated to the steering column and freeing up space in the centre console for stowing items and a wireless phone charger.

Rear legroom is also good. I’m 189cm tall and I can sit behind my driving position with space to spare. Headroom back there is also good thanks to contoured heading which has a ‘carved out’ section for extra space.

Along with the wireless phone charger there are two Type-C USB ports up front and another two for the second row.

There are four cupholders (two up front and two in the second row) and decent sized bottle holders in the doors.

This lack of practicality compared to an SUV or even a station wagon means the Sonata N Line really isn’t the perfect family car.

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 Sonata N Line comes with a 2.5-litre turbo-petrol four-cylinder engine making 213kW and 422Nm, which is plenty of oomph, and it all goes to the front wheels through an eight-speed dual-clutch automatic transmission.

So no, there’s not a diesel version nor an all-wheel drive version, but this sporty engine suits the Sonata N Line perfectly.

That said a hybrid variant would be good seeing it’s 2023.

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.

As we were saying above there’s no hybrid variant of the Sonata N Line and there should be. Actually there is, but Hyundai says it isn't available for the Australian market.

So, this turbo-petrol four-cylinder is all we have and according to Hyundai it uses 8.1L/100km on the combined cycle.

When we tested it at the launch our trip computer was reporting exactly 8.1L/100km, but the roads were clear, the traffic was nowhere to be seen, so you can expect that consumption to climb higher if you’re commuting around the city.

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 Sonata N Line’s performance matches its sporty looks. That turbo-petrol engine is responsive and provides great acceleration, the transmission shifts fast and the steering is nicely weighted and accurate. 

Add to this better rigidity in the car’s structure in this updated model and a feeling of stability thanks to this being a sedan with a low centre of mass and you have a dynamic and enjoyable vehicle in your hands.

Sure it doesn't have the sky-high visibility that comes from the pilot’s seat of an SUV, but the Sonata N Line is for those who like to drive but still want the practicality of four doors, back seats and a boot.

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.

The Sonata N Line is covered by Hyundai’s five-year, unlimited-kilometre warranty. 

Servicing is recommended annually or every 10,000km. There’s no capped price serving but you can buy a 'Lifetime' or a five-year plan that work out to be between $350-$400 on average a year. 

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.
