Abarth 124 vs Mazda MX-5

What's the difference?

The Abarth 124 Spider is a flawed but dramatic little car that should put a smile and a big, fat Italian moustache on any weekend warrior’s face.

As long as you don’t expect it to do much more than that in terms of its daily driving ability, it hits the nail on the head as a spicy alternative to the well-rounded MX-5 formula.

Whether it hails from Hiroshima or not is irrelevant. Its ancestors would be proud.

Now, if only all of them had this Monza Edition’s glorious exhaust…

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.

I love the way the 124 looks. The more you pore over its small frame, the more you discover how different it is to its MX-5 counterpart.

It’s angrier. It’s more beautiful, and it’s definitely more Italian.

References to the original have been tastefully applied without transforming it into bloated caricature. These include the dual indents on the hood, the rounded-out light clusters, and the squared-off rear.

From there it goes beyond the original 124 and seems to take influence from contemporary Italian designs. I would argue there’s more than a little modern Maserati in this car’s tough wheelarches, scoopy mouth, rear light fittings and alloy wheel design.

The quad-exhaust pipes (actually just two tailpipes with four apertures) is arguably overkill, but adds a bit of extra aggression to this car’s rear. I’m not a fan of the oversized Abarth badgework on this car’s nose and rear. It removes a bit of subtelty from the equation, and the one on the bootlid is entirely unnecessary.

I’d also argue our test Monza Edition car looks best with its white paint and red highlights throughout. It’s also available in red and black.

The inside breaks the illusion a little. I’d argue not enough has been done to differentiate the 124 from its MX-5 roots here. It’s all Mazda switchgear.

There’s nothing wrong with that switchgear, of course. It’s well built and ergonomic, but I’d love to have something different to mix it up here. A Fiat 500 steering wheel… some switches that look cool but barely function properly… Just a little more of the Italian personality that’s so well expressed on the outside…

The seats are unique to the Abarth and are lovely, and the red highlights carry through them onto the dash and wheel stitching. The Monza edition has the official logo of the famed Italian circuit between the seats, with the build-number etched on it.

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.

When it comes down to a practicality score, it’s only fair to compare a car like this to its direct competitors. A sports car like this is never going to take on a hatch or SUV in the practicality stakes.

Even so, and just like the MX-5, the Abarth 124 is tight on the inside. I fit inside it perfectly, but there are problems.

Legroom is super tight for me at 182cm tall. I had to adjust to having my clutch foot at an angle, otherwise I’d smack my knee on the bottom of the steering wheel, a problem that also makes this car tough to clamber into. The handbrake takes up a massive amount of room in the limited centre-console space, and as to storage in the cabin? You may as well forget it.

There’s a tiny flip-up binnacle in the centre, shallow enough maybe for a phone and nothing else, a slot under the air-conditioning controls seemingly designed expressly for phones, and two floating cupholders between the seats.

There’s no storage in the doors, nor is there a glovebox. You do get a rather large storage area behind the cupholders, accessible through a hatch opening, but it’s a little awkward to use.

Once you’re in, though, this car fits like a glove in terms of ergonomics. The wheel is nice and low, the seats are surprisingly supportive and your elbow rests nicely on the centre, leading your hand to the excellent short-action shifter. Headroom is tight no matter which way you cut it, but it’s such a small car you hardly expect more.

How about the boot? It’s better than you might hope, but with just 130 litres on offer it’s still no more than a weekender. It’s also less than the Toyota 86/BRZ (223L) which also have back seats, always handy no matter how small they are.

There’s no spare to be found. The 124 has a repair kit only.

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.

Unlike the MX-5 and 86/BRZ combo, which offer a choice of naturally aspirated engines, the 124 carves its own path by dropping Fiat’s 1.4-litre ‘MultiAir’ turbo four-cylinder under the hood.

The word ‘turbo’ should rightly prick your ears in a car this size, but this this is hardly a high-performance unit when compared to its non-turbo counterparts.

Outputs are set at 125kW/250Nm. That power figure might seem a little low when compared to the new 2.0-litre MX-5 (135kW/205Nm) and 86 (152kW/212Nm), but the extra torque is welcome. It comes at a cost,  which we’ll explore in the driving section of this review.

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 124 has a bold-souning official combined fuel consumption figure of 6.4L/100km, which I overshot by quite a margin. At the end of my week, (involving truly mixed freeway/city driving) I landed on 8.5L/100km, which was exactly on this car’s ‘urban’ estimate, so take that as a realistic figure.

It’s also less than I’d expect to consume in an 86 and perhaps also the MX-5, so all-in-all it's not too bad.

The turbo Fiat engine requires a minimum of mid-grade 95 RON unleaded to fill a 45-litre tank.

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.

I drove the 124 up NSW’s Old Pacific Highway from Hornsby to Gosford at dusk on a Saturday. Talk about the right car in the right place at the  right time.

It was absolutely in its element, darting around tight hairpins, then blasting up straights, giving the short shifter a thorough workout. That new exhaust added 150 per cent to the theatre of it as each aggressive down-shift was accompanied by crackling, spitting and barking.

It’s an absolute joy, a proper nod to how cars used to be in the good old days of a ‘Sunday drive’, and thus a proper nod to the 124’s history.

And, of course, it has flaws. Many of them fall into the subjective category on a car like this, however.

Take the engine, for example. I’ve heard endless criticisms of it as laggy and annoying. And it is. Catch the wrong gear and get the revs too low and no matter how hard you stomp that go pedal, you will be stuck fighting a mountain of lag. Seriously. Several seconds of it.

Even trying to ascend my steep driveway had me concerned it was simply going to stall out in first gear.

It’s a bit strange, but then when you’re on the open road it’s worth relishing the challenge that it offers. Grab the wrong gear and this car will let you know how foolish you are. And yet, when you get it right it offers a surge of excitement in the straights that’s arguably far more dramatic than either the MX-5 or 86 can muster.

Another annoyance is the speedometer. It’s tiny and counts 30km/h increments all the way up to 270km/h. How fast was I going, officer? No idea. I have about two inches to tell whether I’m going between 30 and 90, so it’s anyone’s guess.

An obvious benefit of the MX-5 chassis is its go-kart handling, and it seems as though the excellent, fast and direct steering hasn’t been messed with, either. Sure, the suspension is a little crashy, and the convertible chassis a tad rattly, but it’s all part of being that much closer to the road. It would be tough to ask to find a better transmission with its fast, short action and sensible ratios.

Ultimately, the 124 is just plain (literally) old-fashioned weekend fun, offering a challenging but rewarding drive.

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.

It’s a shame that the 124 is only offered from Abarth with a three-year 150,000km warranty. Its counterpart MX-5 is now offered with a five-year unlimited promise, and Fiat could really do with a bit of positive warranty coverage right now.

You’ll need to service the 124 once a year or every 15,000km. Capped price servicing? Ha. No such thing over at Abarth, apparently. You’re on your own.

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.
