Alfa Romeo Junior vs Mazda CX-30

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.

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

About to enter its fifth year in market the Mazda CX-30 is holding up well and this GT SP FWD grade delivers solid value relative to its key competitors, of which there are many. It’s also space-efficient, practical and performs well with top-shelf safety, decent refinement and good dynamic ability.

Alternately, it’s crying out for a hybrid powertrain to improve fuel efficiency, the interior form and function is starting to date and while it meets the market the ownership promise could be sharper. But this little SUV is still worthy of a spot on your new-car short list.

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.

Mazda continues to follow a disciplined design path with everything from the MX-5 sports car to the BT-50 dual-cab ute sharing key attributes like the brand’s signature trapezoidal grille, simple flowing lines and sleek head- and tail-lights, all wrapped up with a subtle hint of chrome here and there.

Car-spotters with the GT SP on their checklist should look out for 18-inch black metallic rims as well as black exterior trim, including the mirror caps. 

Inside, the CX-30 maintains Mazda’s restrained approach with smooth surfaces integrated across the multi-layer dash and primo leather-trimmed seats.

That said, this car is starting to show its age with the multimedia screen plonked on the top of the dash (in typical Mazda fashion) and a largely conventional instrument cluster.

Yes, the main dial is configurable courtesy of a central 7.0-inch TFT screen, but next to more recent arrivals boasting sleek, often twinned, flat screen displays the CX-30 looks and feels out of touch. 

Functionally, there’s a sensible mix of digital controls and physical buttons (points for audio volume and ventilation dials!), but… the multimedia screen can only be accessed by a rotary controller in the centre console once the car is mobile (it works as a touchscreen when you’re stationary).

Some say touchscreens take your eyes off the road so the controller makes sense, but with a sequential app like Spotify it can take a lot of twirls to get to where you want to go, which upsets concentration and takes your eyes off the road, anyway. I’d prefer the relative ease of a quick press on a screen.

Aside from all that, the materials used are high quality with soft-touch surfaces across key contact points and hard plastics confined to high-wear areas. 

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.

At just under 4.4m long, close to 1.8m wide and little over 1.5m tall (with a 2655mm wheelbase) the CX-30 is in the middle of the pack it competes with in terms of key dimensions.

And space up front is more than adequate, with an impressive feeling of roominess for a relatively small SUV.

For storage, there’s a large lidded box (which doubles as an armrest) between the front seats as well as a pair of cupholders in front of the gear-shifter with a bay for wireless device charging ahead of that.

The glove box is big, there are bins in the doors with room for decent size bottles and a drop-down tray for sunglasses sits overhead.

Move to the rear and the amount of space on offer is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, although three full-size adults across the back seat will be an uncomfortable proposition for anything other than short trips. A trio of up to mid-teenage kids will be fine.

Adjustable air vents at the back of the front centre console are a welcome inclusion for back-seaters and storage runs to a map pocket (weirdly, on the back of the front seat only), a pair of cupholders in the fold-down centre armrest and bins in the doors with room for smaller bottles.

In-cabin power and connectivity includes two USB-C outlets and a 12-volt socket in the front centre storage box. No USBs specifically for those in the rear, which is a miss for road trips and no 12V in the boot which can be handy when camping or picnicking.  

Speaking of the boot, cargo volume with the rear seat upright is okay for the class at 317 litres, which expands to a healthy 1479L with the 60/40 split-folding backrest lowered. For comparison the Kia Seltos coughs up 433L with the rear seat upright.

The space is illuminated, there are tie-down anchors to help secure loose loads and there’s a space-saver spare sitting under the floor.

And if you’re keen on towing a tinnie or similar you’re good to go for a 1200kg braked trailer (600kg unbraked).

The Mazda CX-30 G25 GT SP FWD weighs in at $43,140, before on-road costs and our test example features the optional ‘Vision Pack’, the details of which we’ll get to shortly, raising the price $1300 to $44,440. 

Alternate options around that price point include the Hyundai Kona Premium N Line 2WD ($42,500), Kia Seltos GT-Line FWD ($41,850), Mitsubishi Eclipse Cross Exceed 2WD ($40,990), Honda HR-V e:HEV L 2WD ($42,900, drive-away), Nissan Qashqai ST-L FWD ($42,690), Peugeot 2008 GT FWD ($44,490), Renault Arkana Techno FWD ($41,000), Suzuki S-Cross Plus FWD ($41,490), Toyota C-HR 2WD GXL Hybrid ($42,990) and Volkswagen T-Roc Style FWD ($40,590).

That’s quite the automotive smorgasbord, the resulting price and specification cage fight meaning every included feature counts and the Mazda heads into battle with some significant weapons in hand.

Specifically, dual-zone climate control, a head-up display, a 10.25-inch ‘widescreen’ multimedia display, 7.0-inch driver’s multi-information display, 12-speaker Bose audio (with digital radio), wireless Android Auto and Apple CarPlay, ‘Burgundy’ leather seat trim, heated front seats, leather trim on the gearshift and heated steering wheel, wireless phone charging, power-adjustable driver’s seat (with memories), a glass power tilt and slide sunroof and a power tailgate.   

There’s also adaptive auto LED headlights, 18-inch black metallic alloy wheels, radar cruise control (with stop/go), a reversing camera, auto-fold (and tilt) heated exterior mirrors and keyless entry and start. 

It’s an impressive and competitive equipment list for a small SUV under $45K, even before we get to the performance and safety tech covered later in the review.

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.

The CX-30 GT SP is powered by a 2.5-litre, naturally aspirated, four-cylinder petrol engine producing maximum power of 139kW at 6000rpm and peak torque of 252Nm at 4000rpm.

It’s a proven all-alloy unit featuring direct-injection as well as variable intake and exhaust valve timing with drive going to the front wheels via a six-speed auto transmission. 

The AWD version of the GT SP adds an electromagnetic multi-plate clutch pack (managed by a multitude of sensors) to selectively engage the rear wheels, as well. But its engine and transmission combination is identical to this FWD model’s.

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.

The CX-30 GT SP FWD’s official fuel consumption figure on the combined (urban/extra-urban) cycle is 6.6L/100km, the 2.5-litre atmo four-cylinder engine emitting 154g/km of C02 in the process.

It features fuel-saving stop-start and cylinder deactivation functions as standard and over a combination of city, suburban and some freeway running we saw an average of 8.4L/100km, which is average for an SUV in this class. A comparable hybrid package would easily better this result.

Based on the car’s 51-litre fuel tank theoretical range between refills is 772km, which drops to just over 600km using our real-world test consumption number. But the good news is this CX-30 runs happily on cheaper 91 RON ‘standard’ fuel.

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’s rare in 2024 to find a small SUV that doesn’t have at least one turbocharger attached to its engine, the CX-30’s 2.5-litre ‘atmo’ four being one of those increasingly scarce examples.

But Mazda’s been laser-focused on extracting maximum power and efficiency from its non-turbo petrol engines for yonks and this one stands up well.

It doesn’t have the low-down punch a turbo typically delivers but maximum pulling power arrives at a useable 4000rpm and it’s eager enough for easy city and suburban running as well as confident freeway cruising.

Although Mazda doesn’t quote an official number you can expect a sprint from 0-100km/h in around 8.5 seconds, which is quick for the class.

Worth noting engine noise and a raspy exhaust note make their presence felt under acceleration and the throttle isn’t as refined as it could be. Not a huge deal, but a slight jerkiness is evident on initial, especially moderate, acceleration.

The six-speed auto is smooth and fuss-free, the steering wheel paddle shifters on hand if you need to intervene and select a specific ratio. ‘Sport’ mode peps things up, causing the transmission to shift down earlier and up later. But it’s aggressive in that it often holds onto a gear for too long and you find yourself diving back to the default normal setting.

Tipping the scales at just under 1.5 tonnes, the CX-30 is underpinned by a MacPherson strut front, torsion beam rear suspension and ride comfort on typically pock-marked urban surfaces is average for the category. That is, a bit jittery over bumps and corrugations but there’s no bone-jarring going on here.

Steering feel and response is good and the grippy steering wheel helps with a connection to the front tyres. Speaking of which, the standard rubber is high-performance (215/55) Dunlop SP Sport Maxx 050 which is  grippy and commendably quiet. 

Push on into a corner and the CX-30 remains balanced and predictable with body roll well under control. Torque vectoring, by engine and physical braking, is also onboard to reel things in if you overstep the mark.

Braking is by discs all around, vented at the front and solid at the rear, and they wash off speed effectively with a satisfyingly progressive pedal action.

Vision is good, which combined with the CX-30’s compact dimensions and 10.6m turning circle, means parking is easy. Especially when you factor in the hi-res reversing camera and front and rear parking sensors. 

The CX-30 carries a maximum five-star ANCAP assessment from early 2020 when the car was introduced locally.

It scored a stunning 99 per cent in the adult occupant protection category and an impressive 88 per cent for child occupant protection.

Active (crash-avoidance) tech includes AEB (operating from 4.0-160km/h) as well as lane keep assist, lane departure warning, traffic sign recognition, intelligent speed assistance, blind-spot monitoring, front and rear parking sensors, rear cross-traffic alert, a reversing camera and tyre pressure monitoring.

Mazda’s ‘Vision Pack’ is also standard which includes a 360-degree camera view, ‘Cruising & Traffic Support’, driver fatigue monitoring and front cross-traffic alert.

The airbag count runs to seven - dual front and front side, full-length side curtains and driver’s knee.

There are three top tether points for child seats across the second row with ISOFIX anchors on the two outer positions.

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 covers the CX-30 with a five-year/unlimited km warranty which is the norm in the mainstream market, and it’s worth noting a growing number of competitors are now at six, seven or even 10 years, although the latter are typically conditional on authorised dealer servicing. Roadside assistance is provided for the duration of the warranty.

Service is recommended every 12 months or 15,000km and Mazda’s ‘Service Select’ program sets maintenance pricing out to seven years, the lowest over that period being $352 and the highest $626, for an annual average of $459, which is reasonable but not exceptional for the category.

For comparison, a similarly specified Toyota C-HR averages $330 per workshop visit over the same period.
