Mazda MX-5 vs Toyota GR Corolla

What's the difference?

Ultimately, the design and tech changes to the ND MX-5 will be the biggest day-to-day advantages of the updated model, because the mechanical changes don’t make themselves hugely obvious on the road.

If you’re into track days, it’s still a satisfying car to hustle as fast as you can, but it’s at its most accessible on winding roads for weekend drives, where the new differential and track DSC mode won’t come into play as much.

But in a world where accessible sports cars are becoming a rarity, there’s only one rear-drive convertible with a sticker price appropriate for financial mortals, and it’s a pretty damn good thing that it’s the ND MX-5.

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.

Alright, we’ve all seen ND MX-5s, you don’t need me to tell you about its proportions or explain its design elements to you in too much detail, so I’ll give you the headline changes.

At the front and rear are new pairs of LED head- and tail-lights, respectively… obviously, fitting into the spaces the old ones took up.

The DRLS and reverse lights have come off the bumpers for both, and are now part of the main lights at each end - no more DRLs in the front bumper, and the reverse lights have been replaced by reflectors.

There are new 17-inch wheel designs for the base and GT trim levels, too, and there’s a new colour - Aero Grey.

Inside, it’s a shame that the tan Nappa leather interior of the RF Black Roof can’t be had in a manual roadster, because it’s gorgeous, even though the inside still looks refined enough for a simple sports car in its base cloth trim.

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’.

One thing Mazda has significantly changed for the ND is the multimedia screen, now a larger 8.8-inch touchscreen running Mazda’s updated software.

It brings the MX-5 up to date without sacrificing simplicity and makes it a little easier to use. The physical dial and buttons for controlling the screen also remain. The USB-C ports are also new.

Oh, and the MX-5 is the first Mazda model to get Connected Services, which is coming to other Mazda models eventually.

Connected Services allows owners to find, lock, and get alerts for their cars from a phone app, even letting them set curfews to notify them if the car is started during certain hours.

Aside from that, another small tweak is the simplified instrument cluster, which aims to be easier to read even when the roof is open and the sun is bright.

The cabin isn’t built to be plush, it’s built for ‘Jinba Ittai’, Mazda’s philosophy that applies most strongly to the MX-5 which means ‘horse and rider as one’.

And trust me, you feel one with the horse- er, car, when there’s not ample room to move. It’s not restrictive, but it’s cosy. 

Everything’s quite well-placed and it’s not busy with buttons or features in here though, it’s made for focusing on driving. 

One downside is the lack of storage, not even a glovebox, in front of the passenger, and the central storage spot under where your elbow sits is tiny, good for keeping the key fob snug though. Also, the cupholders are able to be removed or swapped between the space behind your elbow, or above the passenger footwell.

There’s also a small storage space between the seats behind where your elbow would sit, though it’s tricky to access while you’re driving.

Then there’s the boot, which is usable for a small amount of luggage at 130 litres in the Roadster and 127L in the RF hardtop.

Finally, as a huge positive, probably the biggest advantage of the ND over any other convertible is how easy it is to open and close the roof in the Roadster. You can do it single-handed, which is great if it starts raining and you’re at a traffic light or able to quickly pull over.

The RF hard-top has a switch that automatically opens and closes the roof section.

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.

Up front, you get one option: a 2.0-litre naturally aspirated four-pot. It makes 135kW and 205Nm, and it’s a delightful little thing, driving the rear wheels only - as it should.

It used to be that the smaller 1.5-litre engine was the more revvy, keen option, rest its soul, but Mazda updated the 2.0-litre to be more eager (and deliver more power) at high revs and basically made the little 1.5-litre redundant.

Anyway, you can have it with a six-speed manual in any variant, or a six-speed automatic in GT guise if you find manual gearboxes difficult or a hassle.

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.

Mazda says the MX-5 uses 6.8L/100km as a manual Roadster, or 7.0L/100km with an automatic gearbox. Or, in the heavier RF 6.9L for a manual and 7.2L for auto.

Not great for a tiny car like this, but pretty good for a sports car!

It’s got a 45-litre fuel tank, takes premium 95 RON or higher, and while it should hypothetically be able to travel more than 600km with its on-paper claims, expect fuel use to sit closer to 8.0L/100km if you’re driving it anything like it deserves.

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.

It feels like every motoring journo under the sun (literally if the roof is off) owns or has owned an MX-5 of some sort.

And the first time you drive one, you might understand why. 

If you spend your days testing and driving a bunch of different cars that aim to be many things at once, it’s refreshing to drive something that aims to be one: fun.

That’s it, the MX-5 feels like it was built to be fun. Not for convenience, not for power, certainly not for the school run.

And fortunately its simplicity remains with this update. All Mazda has done to change the way it drives is attempt to improve the rear limited-slip differential and improve the steering a little by reducing friction in the rack, as well as improve throttle response.

Has any of that changed the way it feels to drive on-road? No, not massively, but the ND was already such a delight that Mazda could have kept this update to purely design and interior tech changes and it would have still been one of the best-value buys around in terms of fun.

The MX-5 still feels relatively softly sprung while still being a dynamic and communicative sports car that’s engaging to drive even at low speeds, and rewarding (or frustrating) to drive fast.

On tight, winding roads, the MX-5 is at home, its soft suspension keeps you humble with its shifting weight and its relatively meagre outputs keep your licence safe.

In fact, despite being slightly compromised as a daily drive, the MX-5 is still plenty of fun even in traffic, there’s something about the satisfying click as the shifter slips into gear, or the little rev matches heading back down through the cogs when approaching a red light.

The 2.0-litre four-pot is a keen unit, and the six-speed manual is light and easy to work with, plus its steering is light without sacrificing road surface feedback - that feedback can quickly turn into cabin noise on a coarse highway which could become a little irritating on a long trip.

But the MX-5 can still be plenty of fun on track, where you’re more likely to get the most out of its new limited-slip differential and Track DSC mode.

It’s equally frustrating and satisfying to hustle the MX-5 around the East Circuit at The Bend in South Australia, where the track is twisty, busy, and unforgiving. Get it wrong, and the MX-5 lurches or slides to let you know you’ve made an error. 

Get it right, however, and the little roadster glides through the corners, camber changes and even over apex kerbs smoothly and carrying impressive speed.

Plus, the electronic assistance won’t usually kick-in until you really need it, a welcome change from cars that are constantly trying to keep you from having fun behind the wheel.

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.

Mazda’s five-year, unlimited km warranty covers the MX-5, including five years of roadside assist.

Servicing costs are pre-set, with intervals every 12 months or 15,000km up to seven years or 105,000km. They cost between $447 and $638, averaging out at about $544 each.

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.
