Infiniti Q30 vs Mazda CX-3

What's the difference?

The Q30 Sport is a left-field choice in the premium hatch segment. For those who don’t care about badge equity and are looking for something different, the Q30 provides maybe 70 per cent the feel of its well-established competition while offering decent value courtesy of standard safety and spec inclusions.

The biggest letdown is how much better it could be with just a little extra in every department. Even in this top-spec the drive experience is a bit generic, and it’s missing an up-to-date multimedia experience limiting its appeal to a younger audience.

Even with its promising mixed heritage, the Q30 hardly feels more than the sum of its parts.

It’s easy to see why the Mazda CX-3 remains such a favourite with small SUV buyers. The Evolve grade tested is dynamically capable, space efficient and well equipped for the money. That said, although I don’t like being ageist, as it starts to creep up on a decade on sale, the market leader is giving ground to the competition in key areas including design, fuel efficiency and refinement. It’s time for a new-generation model, but in the age of electrification, will there be one? In the meantime, this evergreen favourite remains a solid urban SUV option.

The Q30 drew more than just looks for its badge. It genuinely looks like a concept car from a motor show stand. Not the paper mache Mars rover early prototype kind, more like the six-months-before-production kind.

It’s all swoopy with curves cutting all down the sides, and Infiniti has done a good job imprinting the brand’s signature design queues – like the chrome-framed grille and notched C-pillar - on the front and rear three-quarter views.

It’s genuinely hard to tell it shares major componentry with the last-gen (W176) A-Class from the outside and I’d place the overall look somewhere between Mazda and Lexus’ design languages for better or worse.

While the front is swoopy and resolved the rear is a bit busy with lines everywhere and bits of chrome and black trim all over the place. The tapered roofline and high bumpers set it apart from your regular hatchback fare. 

It might grab the eye for the wrong reasons, but it certainly gives the Q30 a slick look when viewed in profile. I wouldn’t call it a bad looking car, but it is divisive and will appeal only to certain tastes.

Inside is simple and plush. Perhaps a little too simple when compared with the new (W177) A-Class with its entirely digital dashboard or the 1 Series with its M bits. One could even argue the Audi A3 has done ‘simplicity’ better.

The seats are nice in the two-tone white-on-black trim and the Alcantara roof is a premium touch, but the rest of the dash is a bit too basic and dated. There’s a smattering of buttons down the centre stack which are replaced with more intuitive touchscreen functions on most rivals, and the 7.0-inch touchscreen looks small, distantly embedded in the dash.

The materials are all nice to the touch, with most important touch-points clad in leather, but it also feels a little claustrophobic, with the abundance of dark trim, thick roof pillars and a low roof-line, especially in the back seat. The switchgear, which is mostly dropped straight out of a Benz A-Class, feels good.

You’re not going to mistake the current CX-3 for anything other than a Mazda, which speaks to the consistency of the brand’s design approach.

Tightly wrapped and neatly detailed the CX-3's exterior has aged well, and thanks to cosmetic tweaks over time it’s still looking clean and contemporary. 

The step up from 16-inch alloys on the lower Sport and Pure grades to 18-inch rims on this Evolve also lifts the look to a more mature, premium level.  

The interior is a simple, fuss-free environment, but in a small-SUV world moving rapidly towards slick integrated screens for multimedia and instrumentation, the CX-3 is showing its age.

The 8.0-inch media display stands proud in the centre of the dash, almost like an afterthought, and the instrument cluster, while okay from an ergonomic point of view, is dated by an analogue tachometer in the centre and LCD-style read-outs either side.

And although it’s always a subjective call, I’m guessing the Evolve’s white and tan interior trim combination won’t be to everyone’s liking, from an aesthetic or practicality point-of-view.

That said, the interior surfaces across the dash, doors and centre console flow into one another nicely, and brushed metal look highlights around key controls and vents enhance the quality feel.

Speaking of which, physical dials and knobs for adjustment of the ventilation system and audio volume is welcome. Maybe old-school is the best school?

However… the multimedia screen can only be accessed by a rotary dial in the front centre console once the car is mobile (it works as a touchscreen when you’re stationary).

Keenly aware there are various opinions on this set-up when it comes to safety. Touchscreens, by definition, take your eyes off the road ahead, so on one hand it makes sense to transfer control to the rotary dial.

But when you’re using a sequential app like Spotify, it can take a hell of a lot of twirls of that controller to get to where you want to go.

Soon you’re grinding your teeth in frustration which upsets concentration and your eyes are well-and-truly off the road, anyway. 

For what it’s worth, I’d prefer the relative ease of a quick press on the screen rather than having to go ‘around the horn’ to hit your favourite track or podcast.

Infiniti calls the Q30 a “crossover” rather than a hatchback and this is best reflected through its pumped ride height. Rather than hugging the ground like the A-Class or 1 Series, the Q30 sits propped up, almost like a small SUV.

There’s also the QX30 which is an even more pumped version of this car complete with plastic guards in the vein of Subaru’s XV. The QX30 is also your only way to all-wheel drive now that the Q30 is front-wheel drive only. 

While the extra ride height means you won’t have to worry about scraping expensive body panels on speedbumps or steep ramps you won’t be wanting to get too brave off the tarmac.

Interior space is fine for front passengers with plenty of arm and legroom, but back seat passengers are left with a small, dark space which feels especially claustrophobic. Headroom is not great no matter which seat you’re in. In the front seat I could almost rest my head on the sun-visor (I’m 182cm tall) and the back seat was not much better.

Rear passengers do score nice seat trim and two air-conditioning vents though, so they haven’t totally been forgotten.

There’s average amounts of storage up front and in the back, with small bottle holders in each of the four doors, two on the transmission tunnel and a tiny trench – useful for keys maybe – in front of the air-conditioning controls.

Even the centre console box is shallow, despite a large opening. Once I had collected enough loose objects on my trip I started to run out of room for things in the cabin.

There are nettings on the back of the front seats and an odd extra one on the passenger’s side of the transmission tunnel.

Power outlets come in the form of a single USB port in the dash and a 12-volt outlet in the centre box.

The boot is a much better story despite the swoopy roofline with 430 litres of space available. That’s bigger than the A-Class (370L), 1 Series (360L), A3 (380L) and CT200h (375L). Needless to say, it ate up two large duffle bags and some extra items we brought with us for our week-long trip.

This is due to its impressive depth, but it does come at a cost. The Q30 only has the sound system’s base and an inflator kit under the boot floor. There’s no spare for long distance trips.

One irritation I have to mention is the shift-lever, which was annoying in its tilt-shift operation. Often when trying to change to drive from reverse or vice versa it would get stuck in neutral. Sometimes I wonder what’s wrong with a shifter which locks in position…

At just under 4.3m long, less than 1.8m wide and a little over 1.5m tall the CX-3’s footprint is squarely city-sized, and no surprise it shares the Mazda2’s 2570mm wheelbase because it’s underpinned by the same platform as the small hatch.

But there’s more than enough breathing room up front and storage options are creative.

Rather than the ubiquitous single storage box between the front seats the CX-3 offers up an adjustable multi-compartment arrangement, with cupholders and bottle retainers ready to flick into position in multiple locations. 

It’s still covered with a padded lid which doubles as an armrest, and there’s also a generous glove box and bins in the doors with space for large bottles, even an overhead drop-down glasses holder.

Move to the back and there’s a surprising amount of head, leg and shoulder room for an SUV of this size. Sure, it’s no limo, but sitting behind the driver’s seat set to my 183cm position, I was pretty comfortable.

Best for two full-size adults in the rear, although a third can squeeze in for short, relatively uncomfortable journeys. Three up to mid-teenage kids will be fine.  

Rear storage includes bottle shaped cavities in the doors, a map pocket on the back of the front passenger seat only (a weird Mazda habit) and dual pop-out cupholders in the fold-down centre armrest.

No adjustable ventilation outlets in the rear, but in a car this compact, their absence isn’t as big an issue as it might be elsewhere.

For power and connectivity, there are two USB-A sockets in the front (one media, one power-only) as well an SD card slot, an ‘aux in’ jack and a 12V outlet. No power options in the rear, which won’t play well with the kids.

With the back seat upright, boot capacity is an okay 264 litres. Enough to accommodate either the largest 124L or the smaller 95L and 36L suitcases from out three-piece set. But not all of them together.

With a bit of not so gentle persuasion, the large CarsGuide pram just squeaked in, but lower the 60/40 split-folding rear backrest and available space expands to 1174L.

Tie-down anchors to help secure loose loads is a plus and a speed-limited space-saver spare sits under the boot floor.

And if you need to hook up a small boat or other lightweight trailer, the CX-3 Evolve is rated to 1200kg (braked) and 640kg (unbraked).

At $31,050, before on-road costs, the G20 Evolve sits in the middle of a five-model CX-3 line-up, which starts with the $G20 Sport ($26,800) and finishes with the G20 Akari ($38,620).

It competes with nine other light SUVs, and to the end of November 2023 has more than doubled the sales volume of its nearest competitors.

Supply constraints may have played a part, but the CX-3 Evolve is way ahead of its direct rivals, the Hyundai Venue Elite ($28,750), Kia Stonic GT-Line ($30,790), Toyota Yaris Cross GXL Hybrid ($33,000) and VW T-Cross 85TFSI Life ($30,990).

Aside from the safety and performance tech we’ll get to shortly, standard equipment includes auto LED headlights and DRLs, rain-sensing wipers, climate control, cruise control, a leather-trimmed steering wheel, an 8.0-inch multimedia screen, six-speaker audio with digital radio plus Android Auto (wired) and Apple CarPlay (wireless) connectivity, sat-nav, keyless entry and start, front and rear parking sensors, a reversing camera and 18-inch alloy wheels.

Standard seat trim is white synthetic leather with tan synthetic suede inserts (also applied to the doors and dash).

That’s a pretty handy roll-call of included features in this part of the market, which meets or exceeds similarly priced competitors.

For 2019 the Q30 has had its list of engines trimmed from three to just one. The diesel and smaller 1.6-litre petrol engines have been culled, leaving a 2.0-litre petrol.

Thankfully, it’s a strong unit producing a once-V6-range 155kW/350Nm across a wide band from 1200-4000rpm.

It feels responsive and isn’t let down by a slick-shifting seven-speed dual clutch automatic transmission.

The new-generation A-Class equivalent, even in 2.0-litre A250 guise produces less torque with outputs of 165kW/250Nm, so for the money the Infiniti scores a solid serving of extra punch.

The CX-3 is powered by a 2.0-litre, four-cylinder petrol engine sending drive to the front wheels via a six-speed auto transmission.

The all-alloy unit features direct-injection and variable valve timing to produce 110kW at 6000rpm and 195Nm at 2800rpm.

Over my week-long test the Q30 returned a figure of 9.0L/100km. I was a little disappointed with this figure given much of the distance covered was cruising at freeway speeds. 

It’s made worse when you pitch it against the claimed/combined figure of 6.3L/100km (not sure how you could achieve that…) and the fact that I left the irritating stop-start system on for much of the time.

For a leader in the luxury hatch class consider the Lexus CT200h which makes full use of Toyota’s hybrid drive and pitches a fuel consumption figure of 4.4L/100km.

The Q30 has a 56-litre fuel tank and takes a minimum of 95 RON premium unleaded.

Mazda’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 6.3L/100km, the 2.0-litre four-cylinder emitting 143g/km of CO2 in the process.

That’s an impressively small emissions figure for a 2.0L petrol engine, more in line with smaller-capacity engines.

Stop-start is standard and over a week of city, suburban, and some freeway running, we averaged 7.4L/100km (at the pump), while the car’s on-board computer indicated 7.1L/100km for the same period.

Minimum fuel requirement is 91 RON ‘standard’ unleaded (or E10) and you’ll need 48 litres of it to fill the tank.

Using the official number, that translates to a driving range of around 760km, which drops to roughly 650km using our real-world figure.

Thanks to its shared underpinnings with the A-Class the Q30 Sport drives largely like you would expect a premium hatch to drive. It’s just lacking a bit of character.

The engine is responsive, the transmission is fast and the availability of peak torque from just 1200rpm will lead to spinning the front wheels if caution is not applied. Power is no real issue.

Although Infiniti says it has tuned the Q30 in Japan and Europe, the ride has an undeniably Germanic flavour. It doesn’t feel quite as tight as the A-Class or 1 Series but it doesn’t feel as soft as the CT200h, so it strikes a decent balance.

The Q30 uses MacPherson strut suspension in the front and multi-link at the rear, more suited to a premium car than the torsion bar rear on the new Benz A 200.

The wheel has a nice amount of feedback, and thankfully doesn’t use the larger Q50’s strange ‘Direct Adaptive Steering’ which has no mechanical connection between the driver and the road.

If you’ve driven a decently-specified A-Class before the drive experience will feel familiar. The added ride height seems to remove a bit of feel from the corners, however.

There’s also the inclusion of three drive modes – Economy, Sport and Manual. Economy mode seems to be the default with Sport simply holding gears for longer. Steering-wheel mounted paddle-shifters could be used to mill through the seven gears in 'Manual' mode, although this didn’t add much to the experience.

The addition of active cruise control and adaptive high beams proved to be fantastic for reducing fatigue on long highway stints during the night, but the lack of a padded surface on the inside of the transmission tunnel proved uncomfortable for the driver’s knee on longer trips.

I persisted with the stop-start system to test it, but it proved slow and irritating. Under normal circumstances it would be the first thing I’d turn off.

Visibility was also a bit limited out the rear three quarter courtesy of the low, swoopy C-pillars.

The CX-3’s compact size makes it easy to steer through tight city and suburban streets. 

It weighs in at just under 1.3 tonnes, which is marginally lighter than most of its key competitors, and acceleration is sprightly with the 0-100km/h covered in less than nine seconds.

Close to 200Nm of pulling power is plenty for a car in this class and unusually for a non-turbo engine, peak torque arrives at a relatively low 2800rpm, so there’s ample mid-range urge.

The downside is the 2.0-litre, four-cylinder engine makes its presence felt inside the cabin, with mechanical noise noticeable even at around-town speeds. Not a conversation stopper by any means, but it’s there.

No complaints with the six-speed auto transmission. It’s smooth and the ratios keep the car in its performance sweet spot nicely. It also shifts into sequential ‘Manual’ mode if your prefer or need to call the shots.

Electric ‘drive-by-wire’ throttle response is smooth, but flick the console-mounted rocker switch to ‘Sport’ and things become more urgent, with the transmission shifting down earlier and holding on to ratios longer.

The steering is evenly weighted for easy parking and road feel is good. Speaking of parking, a 10.6m turning circle is large-ish for such a diminutive SUV, but surprisingly, not out of line for the category.

Suspension is by struts at the front and torsion beam at the rear, and despite the CX-3’s relatively short wheelbase and the Evolve’s bigger 18-inch wheels, ride comfort over typically pock-marked urban roads is surprisingly good. The Toyo Proxes R52A (215/50) tyres are also quiet and reassuringly grippy.

Braking is by generous ventilated discs at the front and solid rotors at the rear, and they’re more than up to the task of calmly washing off speed in this city-sized SUV. 

The front seats proved comfy and supportive on test, although you’ll have to step up to the next Touring grade to score electric adjustment for the drive or lumbar control of any description.

The CX-3 had a maximum five-star ANCAP score from 2015 to 2022, but the independent safety body’s assessments have a seven-year shelf life and the compact SUV is currently ‘unrated’.

That said, active (crash-avoidance) tech is up to the mark with AEB (forward and revers with front pedestrian detection), blind-spot monitoring, lane departure warning, front and rear parking sensors, rear cross-traffic alert, a reversing camera and smart city brake support (front and rear) included.

If a crash is unavoidable, there are six airbags onboard (dual front, dual front side and side curtain), the CX-3 showing its age somewhat with the absence of the now increasingly common front centre bag designed to minimise head injuries in a side impact.

There are three top tethers for baby capsules/child seats across the rear row with ISOFIX anchors on the two outer positions.

As with all Infiniti products, the Q30 is covered by a four-year/100,000km warranty and a three-year service program can be purchased with the car. Pricing was not available for the 2019 Q30 model year at the time of writing, but its 2.0-litre turbo predecessor averaged $540 per service once a year or every 25,000km.

Credit where credit is due, the Q30 edges out the European competition by a year of warranty length and general service pricing. This market segment is still wide open for a manufacturer to take the lead offering five or more years of warranty coverage.

Mazda covers the CX-3 with a five-year/unlimited-kilometre warranty, which is the current market standard. Roadside assist is included for the duration. 

Recommended service interval is 12 months/15,000km, and the average annual cost for each workshop visit, for the first seven years, is $438.

An average under $450 is alright, but Toyota’s capped price figure of $195 per workshop visit for the first five years of C-HR ownership puts it in perspective. Mind you, Toyota’s charges step up considerably after that fifth year.
