Subaru BRZ vs Mazda MX-5

What's the difference?

Just in case you haven’t figured it out, we’re deeply in love with the BRZ tS. It’s a sublime beauty with a tantalising breadth of talent, while still being affordable and practical enough as an everyday run-around.

And, yep, even with the auto, the BRZ tS is its own and very special thing. Do it before coupes die out completely. 

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.

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

Compared to the previous model, the latest BRZ has similar proportions but has changed in a few important ways.

For instance, the body is about 50 per cent stiffer than before. The bonnet, front mudguards and roof are now aluminium, and the fuel flap is plastic. This helps bring a 4.0mm drop in the centre of gravity, which benefits handling and ride dynamics.

The BRZ is longer then the first-generation version by 25mm (at 4265mm), has a wheelbase that’s been stretched by 5.0mm (to 2575mm), is 15mm shorter (at 1310mm) and has wider rear tracks (at 1550mm), but overall width (at 1775mm) remains the same.

Being a tS, STI has fitted special badges around the car, different alloys and uprated (Brembo) brakes, amongst other things. And the changes are just as subtle inside.

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both, and are now part of the main lights at each end - no more DRLs in the front bumper, and the reverse lights have been replaced by reflectors.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

Is there anything more retro than sitting down low in a sports car with just centimetres separating your buttocks from bitumen?

This is the BRZ experience, but once sat snug, ensconced in superbly supportive sports seats, you forget all about the fumbled entry and graceless egress that awaits and instead revel in the moment.

Arms outstretched, hands gripping a perfectly-sized wheel, ahead of crisp electronic instrumentation, with controls so intuitively placed and presented that soon everything’s operated via muscle memory, Subaru has nailed the ergonomics.

Oh, and the joy of a handbrake lever! It's just so naturally and beautifully driver-orientated. 

Okay. Owners of the original (ZD6) generation will already know all this. So what’s changed? Besides nothing conceptually, basically everything executionally.

The dated old dash has been ditched for a dated – but much prettier – new fascia, that’s all horizontal layers and matt black plastic, just like Japanese sporty coupes were in the 1970s and ‘80s. Except for the 8.0-inch touchscreen, of course, which looks a little aftermarket with its low-res TomTom nav, but is easy to figure out and a cinch to use on the go.

The climate control and toggle switches are lovely to use, there’s bottle storage in each door and, as a bonus for going automatic, an extra beverage holder to the pair beneath the centre-console lids exists. This matters if you're regularly transporting thirsty passengers cramped out back. More on that in a moment.

Other than the contortions required to get in and out, the BRZ’s is actually shockingly practical – from the surprisingly good all-round vision afforded by all that glass area as well as thinner pillars and sleeker exterior mirrors than before, ample ventilation and handy storage, to front-seat comfort and a compliant ride.

Plus, you’ll soon learn that the frameless doors provide easier entry and exiting when their windows are down. You wouldn’t think twice about commuting in this baby. Cancel that expensive small SUV order now!

The tS’s extra suede-esque upholstery, baboon’s butt red starter button and STi instrumentation cluster lift the ambience above the cheap sports car vibe of the 2012 original, while the whole ensemble is superbly screwed, clipped and/or glued together.

Gripes? For such a recent model, the lack of a USB-C port anywhere in the BRZ is an oversight. There are no overhead grab handles to help haul yourself out. At speed there's too much road noise. And only the front passenger seat has a single-action slide-and-tilt motion with return for getting through to/from the back, meaning you’re forever grappling with seat levers if you need to enter/exit from the driver’s side.

Now, granted, the rear pair of seats are occasional-only for taller folk, but there’s every chance the '+2' element of the Subaru is the main reason you’d be pondering one of these over, say, the strictly two-seater MX-5.

At 178cm, your tester just about hits the height limit for back-seat accommodation. Actually, the cushion and backrest base are thoughtfully padded and angled, but scalps scrape ceiling and/or glass depending on posture, the front-seat occupants need to slide their chairs forward for knees to fit and there’s barely any space for bigger feet.

But then, this is not the point of a coupe. The fact the BRZ is fine for shorter trips adds another level of practicality, even if there are no grab handles or reading lights to access. And, thoughtfully, the cabin engineers created the centre console lid to remain open for rear-seat access to cupholders, two USB-A ports and a single aux (!) outlet.

That's why the auto's extra cupholder comes in so handy.

Further back, the one-piece backrest folds flat to boost cargo-carrying practicality and versatility, since the boot is a modest 201 litres in capacity. And, it’s now easier to do that thanks to a boot-sited backrest release. It beats having to clamber inside the car every time, as per the earlier generation BRZ.

Keep in mind the tS loses the other BRZ grades’ full-sized spare wheel, presumably in the name of dynamic precision. A tyre-inflation kit is a poor substitution in puncture-prone Australia.

Oh well. At least you’ll be in a pleasant and charming coupe environment whilst you wait for roadside assistance.

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.

Getting into an MX-5 is now a little more expensive, with the base manual Roadster up by $2310 to now start from $41,520 before on-roads.

The top-spec soft-top GT RS is now $51,640, or $2800 more than before.

Pricing for the RF hard top is also similarly bumped up, a base manual costing $46,250, and the most expensive GT RS at $56,140.

There’s also a Black Roof edition which comes with tan Nappa leather inside, but that’s only available in an automatic RF, which is possibly the biggest downside to the 2024 range.

Base models get cloth seats, while GT and GT RS models get heated leather seats. The GT RS also comes with stiffer Bilstein dampers, Brembo front brakes, a bracing strut between the front suspension towers and a DSC-Track mode. The difference there is noticeable, so it's worth the extra spend for the more keen driver.

The higher overall costs bring updated tech, a new 8.8-inch touchscreen and a new limited slip-diff in manual versions, plus tweaked mechanicals like improved acceleration response and lower steering rack friction.

But they do look a tiny bit different too.

Under the BRZ’s bonnet is the same 2.4-litre horizontally-opposed ‘boxer’ four-cylinder petrol engine, with double overhead cams and direct-injection.

Power is rated at 174kW at a heady 7000rpm while the 250Nm torque maximum kicks in at 3700rpm. Tipping the scales at about 1310kg, the power-to-weight ratio is an impressive 133kW/tonne.

The boxer engine drives the rear wheels only via a six-speed manual or, in this case, an Aisin-supplied six-speed torque-converter automatic transmission with paddle shifts.

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 BRZ is not tuned to save money at the petrol bowser.

What did we manage? Air-con on always and driven hard often with fuel-sapping performance testing included, our not-fully-run-in tS returned a commendable 10.2L/100km, while the car’s trip computer read out was 9.7L/100km.

Subaru says owners of the automatic model should expect to average 8.8L/100km on the combined cycle. Choosing to go manual bumps that up to 9.5L/100km.

As a result, the carbon-dioxide emissions rating is 201g/km (auto) and 217g/km (manual).

Note that filling the BRZ auto’s 50-litre fuel tank with the required 98 RON premium unleaded petrol should eek out nearly 570km between refills using the combined cycle figure.

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.

The brilliant thing about the BRZ/GR86 twins is they’re just so great to drive regardless of transmission.

And, after a week behind the wheel of the BRZ tS auto, there are even unique benefits to make a very strong case in its favour over the admittedly incredibly satisfying manual.

The numbers tell a compelling story.

With an impressive 133kW/tonne (or thereabouts) thanks to a larger engine (with 18 per cent more power and 20 per cent more torque than before) and a tight-ratio six-speed auto, the BRZ springs off the line with an almost frenetic liveliness, providing snarly, punchy performance right to its lofty 7500rpm red line.

Select manual mode and the auto will also hold bounce off the rev limiter.

Okay. It’s still not sports car fast, per se, with relatively modest outputs and a 0-100km/h time in the mid-six second bracket, but what there is works hard to make you feel like you’re going very quickly. That said, the BRZ will bowl along at quite a cracking pace.

Select 'Sport' mode, and there’s even more urgency, with the sweetly-calibrated auto hanging on to its ratios a little longer. Here’s where the Tiptronic-style lever/paddle shifters come into play, allowing for that extra level of interactivity.

Even with out test car's odo well under 1000km, this boxer engine has a very deep set of lungs and a lot of bandwidth to explore.

The generational change that saw the swapping out of the old 2.0-litre for this torquier 2.4L seems to be for the benefit of the auto.

And that’s not even the best bit.

The BRZ skates along with an Olympian’s confidence and control, providing an agility and grace reserved for Porsches, Lotuses and the like.

And it’s not just the wonderfully tactile steering at work either, because this possesses that rare seat-of-the-pants connection that makes the driver feel like part to the car.

Suspension is by MacPherson struts up front and a double-wishbone arrangement. Subaru reckons weight distribution is a close-to-ideal 53:47 front/rear.

Like all second-gen BRZ/GR86 models, the architecture underneath is loosely based on Subaru’s small-car platform that dates back decades, though it has been significantly updated and improved along the way.

If you love the sort of driving where you long to sense the road, corner with the throttle and swing out the rear of the car using just your hips, then the tS is your sort of sports car.

From the brilliant brakes to the nuanced tune of the traction control systems, balanced precision is the name of the game here. It tingles senses like an ASMR sensation. The fact this is as an auto does not change anything.

And, you know what? The uprated STI dampers even seem to benefit ride quality, because while the tS is obviously a taut and muscular drift-ready machine, the suspension is never too stiff or hard, allowing this BRZ to be more than capable as a commuting machine.

Yep, even over craggy inner-urban pot-holed and tram-lined roads, the Subaru’s comparative comfort and sophistication only endeared us to it even more.

So, surely there are downsizes, right? Well, the Michelin Pilot 4 215/40R18 tyres sure love to amplify road noise inside. This is not a quiet car over some of our coarser bitumen surfaces, and it can quickly become tiresome.

And… that’s it for criticism from a driving point of view. The BRZ tS can put a smile on your face just like MX-5s and Caymans can. Even/especially the auto if you will seek to schlepp around in one every single day with a minimum of fuss.

And all for around $52K drive-away. Bargain. Where do we sign up?

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 ND MX-5 actually scored five stars with ANCAP back in 2016, even though its score has now expired. It’s not obvious how well it would fare under newer, stricter tests, given the small car’s lack of advanced driver assistance - not that that’s a bad thing in the case of a sports car.

Still, for a two-seat convertible, the MX-5 has a decent list of kit to keep you safe including front and side airbags, alerts for driver attention, blind spots, lane departure and rear-cross traffic, parking sensors and a reversing camera, belt pretensioners and side-impact door beams and even automatic Smart City Brake Support.

All Subaru BRZs come with a five-year/unlimited kilometre warranty, as well as one year’s free roadside assistance. Service intervals are at 12 months or 15,000km, whichever comes first.

There is five years/75,000km of capped-price servicing available, with the first starting from around $365, then stretching to $586, $460, $825 and $380 for an average of $523.

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.
