Alfa Romeo Junior vs Mazda MX-5

What's the difference?

The Alfa Romeo Junior is a cute car that’s charming and smile-inducing. It deserves to sell well but ultimately this will come down to whether the Australian public is receptive.

There is plenty of competition out there and if you're wanting something design-led, it's hard to look past this without spending much more money.

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.

This is such a cute and tiny car with Alfa Romeo trying its hardest to sandwich all of its hallmark design traits in. It’s certainly a busy design on the outside which I don’t love right now, but I imagine I’ll grow to like it with time.

At the front there’s a special grille as standard that features Alfa Romeo script, plus an offset license plate and cool matrix LED headlights with the company’s ‘3+3’ lighting signature.

Around the side the 18-inch alloy wheels have a flower petal-like design, hidden second-row door handles, as well as a hidden serpent (Biscione) easter egg that’s laser etched into the C-pillar.

The rear of the Junior is my least favourite angle. It tries too hard to look more like a hatchback than a crossover SUV with the slanted rear window and the big black slab where the tail-lights are.

The twin exhaust pipes are a cute look, however, especially given the engine doesn’t scream performance credentials on paper.

Inside there’s an obvious attempt at making the cabin look and feel driver-oriented and sporty.

I like the seats which have a red section that runs down the backrest and onto the seat base. It helps break up the black finishes nicely.

Speaking of, however, there's a sea of black finishes throughout the rest of the cabin. I’d like to see some more silver or chrome accents as the glossy piano black may not age well.

There is interior ambient lighting around the cabin with a customisable colour, which looks great in low-light situations. It particularly pops in the large circular air vents which flank the dashboard and are shaped like cloverleaves.

If you look closely you may notice the Junior shares a lot of its physical switchgear with the related Jeep Avenger. Examples include the steering wheel buttons, gear selector, starter button and the physical climate control switches.

While there’s an argument to say that this cheapens the feel of the Junior, I’m thankful there is physical switchgear in this car to begin with. Plus, the Junior does look different enough as it is.

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 front seats in the Junior are very comfortable for longer drives. The driver’s seat in particular offers six ways of electric adjustability and a massage function. You don’t see features like that very often on a tiny SUV.

Ahead of the driver there’s a leather-wrapped steering wheel. It’s surprisingly slim which makes it nice to hold. There are also paddle shifters on the back which could be more pronounced.

As standard there’s a 10.25-inch digital instrument cluster which emulates analogue dials for the tachometer and speedometer. While the screen is high-res and clear, it’s interesting that Alfa Romeo chose to emulate dials in a digital way rather than just have physical ones, especially because you can’t change their appearance.

There’s a section in the middle that has a few different informative pages you can cycle through. I’d love to see more configurability given there’s limitless possibilities with a screen.

Moving across there’s another 10.25-inch screen for the central multimedia system. It certainly makes up for the lack of configurability in the digital instrument cluster and you can create and customise five different home page screens with a vast array of widgets. It’s fairly clever though at some point it feels like overkill.

There aren’t many menus or sub-menus to get lost in, however, the home button took me a while to locate. It’s above the touchscreen in a small pod of physical buttons alongside the hazard lights and door lock switch.

Underneath the touchscreen there’s a wireless phone charger, plus USB-C and USB-A charger ports.

The engine start button is mounted prominently on the centre tunnel with the lightswitch-like gear selector directly behind it. It’s mounted a little too close to the centre armrest which means craning my arm like a T-Rex to use it.

Other amenities up front include a deep console area with configurable cupholders, a sliding centre armrest with a cubby, as well as a tiny glovebox.

It’s very clear the second row of the Junior isn’t the focus. At 182cm tall I need to splay my legs on either side of the driver’s seat in my desired driving position. Despite this, toe room and headroom is adequate, even with the optional sunroof.

The second row isn’t a place anyone would want to spend too long in. Kids would likely suit better, plus there are top-tether points on all three rear seats and ISOFIX mounting points on the outboard rear seats.

Amenities are limited to a single USB-C port in the second row. There are no air vents or centre armrest. You need to make your own entertainment.

At the back there’s a hands-free power tailgate, which is rare for a vehicle of this size. Once it’s open, the available boot space is decent, especially for such a small car. There’s 415L of boot space with the rear seats upright.

The area itself is fine. There’s no load lip which allows you to get things in and out with ease, plus there’s a two-tier boot floor, allowing you to stow items under the floor away for prying eyes.

In terms of boot-related amenities there’s a 12V socket, a light and some hooks. It’s fairly standard back there.

Unfortunately there’s no spare wheel as standard in the Junior line-up. Instead there’s a tyre repair kit which is not super handy if you have a tyre blow out.

Thankfully you can purchase a space-saver spare wheel for the Junior Ibrida for $314 as a genuine accessory. It would be better if this came as standard given there’s the space for it.

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.

The Junior Ibrida is powered by a 1.2-litre turbocharged three-cylinder petrol engine with 48V mild-hybrid assistance.

In the six-speed dual-clutch transmission is a 21kW electric motor that’s fed by a 0.9kWh lithium-ion battery pack.

It’s worth noting that this is the exact same engine set-up that features in a growing number of Peugeot models locally, including hybrid versions of the 2008, 3008, 5008, 308 and 408.

Total system outputs are 107kW and 230Nm which is far from class-leading. Alfa Romeo claims the 0-100km/h sprint takes 8.9 seconds.

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 Junior Ibrida has a claimed fuel consumption of just 4.1L/100km, which is solid for a mild-hybrid vehicle.

There’s a 44L fuel tank which requires a minimum of 95 RON premium unleaded petrol.

During our 200km drive loop on the launch which consisted of mixed and spirited drive, we returned an average of 5.4L/100km. However, during one section with fewer twists and turns we saw an average of 4.0L/100km, which is incredible.

Using our as-tested fuel consumption there’s a theoretical range of 815km.

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.

Starting up the Junior Ibrida, the turbo three-cylinder engine roars to life with an off-beat, thrum-y sound.

If the engine is bone cold, it’ll stay on to get the fluids up to operating temperature. Once this happens it will happily switch off.

Initial acceleration is typically done on electric power alone and if you don’t press the accelerator too hard it’ll stay in EV mode at city speeds. It’s very electric-heavy for a car that’s technically only a 48V mild-hybrid.

At many points the engine switches off at speeds up to 80km/h, especially if you’re travelling on flat ground. Even at 100-110km/h, it’ll switch off if coasting.

Something to note is the electric motor is part of the six-speed dual-clutch transmission which means you can sometimes feel gear changes even when driving in EV mode. You do get used to this.

A positive of the electric motor being in the dual-clutch is it helps iron out awkward pauses and jerks that this type of transmission typically presents. It’s still not perfect though.

If you press the accelerator harder or the battery charge gets lower, it’ll inevitably fire up the three-cylinder engine. It makes a rorty note during acceleration which is fun to listen to.

The transition from electric to petrol is generally seamless. There can be a slight shudder when the three-cylinder first fires up at low revs, but I’ve experienced much worse in other cars.

There’s only one setting for regenerative braking, which is fairly strong and almost one-pedal-driving like. It takes a bit to get used to the feeling. You do still need to put your foot on the brake pedal to come to a complete stop.

With the combination of the petrol engine and electric motor, acceleration is far from break-neck but it’s far from slow. The fact it doesn’t have much power actually makes this car more endearing, especially because it’s rewarding to drive.

The steering in the Junior is communicative and direct. It's a joy to take corners in as the feel errs more on the lighter side. It almost has a Mini-like go-kart feel as the car feels so nimble.

Additionally, the ride is composed and settled, even at higher speeds on rough roads, which is rare for small vehicles. This is likely because the Junior only has 18-inch alloy wheels with a decent amount of tyre sidewall, rather than the low-profile 20-inch units that are offered in the Veloce Elettrica overseas.

On the highway the Junior’s cabin is surprisingly quiet. You can’t hear the three-cylinder once you’ve reached your set speed and there’s also minimal wind/tyre noise.

Lastly, the safety systems do a good job at working but not being annoying. The worst culprit is the intelligent speed limit assist which chimes when you go over the signposted speed limit.

If it does grate you too much, you can easily switch it off in a dedicated advanced driver assist system (ADAS) menu that can be reached via a shortcut button near the hazard lights. It’s as easy as that.

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.

Like other Alfa Romeos, the Junior is covered by a five-year, unlimited-kilometre warranty.

There’s also five years of roadside assistance as standard. An additional 12 months of coverage can be added for the lifetime of the vehicle every time you service at an authorised Alfa Romeo dealer.

Logbook servicing is required every 12 months or 15,000km, whichever comes first. The first five services are capped and total $3105.84, which averages out to around $620 each.

This seems pretty expensive for such a small car, but it's only a touch pricier than the Lexus LBX.

It’s clear maintaining this vehicle with its dual-clutch automatic transmission and mild-hybrid components is costly in the long run.

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.
