Infiniti Q30

Summary

Mazda3

We all know that X means buried treasure in the world of children’s book pirates, but it’s looking like it could hold similar relevance for what lies under the bonnet of future Mazdas.

We first officially heard about Mazda’s industry-leading Skyactiv-X technology at the brand’s Global Tech Forum in Germany two years ago, but now we’ve ventured back to Germany to drive it in production form ahead of its Australian arrival aboard a new flagship version of the Mazda3 early next year. 

No other manufacturer has managed to productionise compression ignition for a petrol engine, and with an underlying intention to make the combustion engine work better for everyday driving, in the face of the electric-focus of all other global brands, this could be the most exciting technological development of my career.

Why invest so much in combustion engines if every other major brand is beginning to treat them like yesterday’s news? While the Japanese government predicts that 52 per cent of new cars sold in 2030 will use some form of electrification in their drivetrain, the same data suggests 90 per cent will still use an internal combustion engine as at least an element of their drivetrain. That’s 90 per cent of the market, more than a decade from now.

Infiniti Q30

Welcome to the future - where your Mercedes-Benz is a Nissan and your Nissan is a Mercedes-Benz. 

Lost already? Let me catch you up. Infiniti is the premium arm of Nissan, in much the same way Lexus is the premium arm of Toyota, and the Q30 is Infiniti’s hatchback. 

Thanks to the state of various global manufacturing alliances the Q30 is mechanically, largely a previous-generation Mercedes-Benz A-Class, with a similar arrangement seeing the new Mercedes-Benz X-Class ute comprised largely of Nissan Navara underpinnings.

Recently, the Q30 has had its range of variants trimmed from a confusing five down to two, and the one we’re testing here is the top-spec Sport.

Make sense? I hope so. The Q30 Sport joined me on an 800km trip along the east coast in the height of summer. So, can it make the most of its German/Japanese roots? Read on to find out.

Verdict

Mazda38.4/10

Unlike most big technological advancements, this isn’t about extra performance or reinventing the wheel, it’s about Mazda’s bigger picture approach to deliver the best mobility solutions for right now, while still planning for electric and fuel cell vehicles in the future.

That may sound like a line straight out of the Skyactiv-X press release, but Mazda’s realistic approach to our continued dependence on combustion engines is commendable. 

My final judgement will have to wait until we know how much more it will cost over a regular Mazda3, but I can say the technology works really well and should really suit Australian conditions.

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


Infiniti Q306.9/10

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.

Is the Q30 Sport different enough that you’d consider it over its premium hatch rivals? Tell us what you think in the comments below.

Design

Mazda3

Aside from the stunning good looks of the new Mazda3, the only visual distinctions the Skyactiv-X version scores over a regular high-sec model are bigger exhaust tips like those seen on the latest version of the Mazda6, and a Skyactiv-X badge in place of the regular models’ Skyactiv-G. 


Infiniti Q307/10

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.

Practicality

Mazda3

It’s a similar story for practicality, except it’s completely identical to the regular Mazda3 this time. So expect the same decent interior packaging and convenience for four adults, with a 295L VDA boot and a space saver spare tyre under the boot floor. 


Infiniti Q306/10

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…

Price and features

Mazda3

This is probably the biggest question mark above the Mazda3 Skyactiv-X’s head for now, with all we know being Mazda Australia’s plan to launch it as a new top-spec version, so sit above the existing $36,990 G25 Astina flagship. 

How far above will be the clincher, and given it’s not likely to quite match the performance of the G25, it will depend on what value you place on outright driveability and a marginal fuel saving over the base 2.0-litre engine. 

Like the rest of the Mazda3 line-up, we also expect to see the Skyactiv-X with a choice of hatch or sedan bodystyles with either manual or automatic transmissions.


Infiniti Q307/10

If you’re shopping in this segment, there’s a good chance you’re not looking for a bargain buy, but the Q30 shines in some areas its competition doesn’t.

A promising start is the complete lack of a lengthy and expensive options list with items which should be standard. In fact, apart from a reasonable set of accessories and the $1200 premium 'Majestic White' paint, the Q30 has no options in the traditional sense.

The base Q30 scores 18-inch alloy wheels, LED headlights with high-beam assist, heated leather seats, flat-bottomed leather steering wheel, leather trim on the doors and dash, Alcantara (synthetic suede) roof-lining and a 7.0-inch multimedia touchscreen supporting DAB+ digital radio and built-in navigation.

Our Sport adds a 10-speaker Bose audio system (which could have been better…) dual-zone climate control, a fixed panoramic sunroof, fully-electric front seats and Nissan’s 360-degree ‘around view monitoring’ parking suite.

It might have premium aspirations, but value-wise Q30 is still specified like a Nissan.

The standard safety suite is also reasonably impressive, and you can read more about it in the safety section of this review.

Our Q30 Sport comes in at a total of $46,888 (MSRP) which is still premium money. The price pits it against the BMW 120i M-Sport (eight-speed auto, $46,990), Mercedes-Benz A200 (seven-speed DCT, $47,200) and fellow Japanese premium hatch act - the Lexus CT200h F-Sport (CVT, $50,400).

Herein lies the Q30’s biggest problem. Brand recognition. Everybody knows the BMW and Benz hatches by virtue of their badges alone and the Lexus CT200h is known by those who care about it.

Even without the extensive options list, it makes the price of entry against such established competition tough. While you might see a couple of them around Sydney, the Q30 is a relatively rare sight which garnered more than a few quizzical looks in the towns of NSW’s mid-north coast.

The standard spec is also missing the all-important Apple CarPlay and Android Auto connectivity. It rendered the 7.0-inch multimedia screen clumsy and largely useless, although the old-fashioned built-in nav gives peace-of-mind when you’re out of phone reception range.

If you have an Apple phone you can make use of the iPod music playback feature via the USB port.

Engine & trans

Mazda3

What’s compression ignition again? It’s basically how a diesel engine works, by using extreme pressure instead of spark plugs to burn fuel. Skyactiv-X still uses spark plugs, but only to kick off the ignition process and act as a safety net for cold starts and other edge cases, while extreme compression makes for much more effective combustion, which means improved efficiency. 

This combustion efficiency means the engine can use a much leaner fuel-to-air mixture, and make more power and torque with less fuel and even less wasted fuel out the exhaust. Mazda describes it as delivering diesel-like torque and fuel consumption, with the power, responsiveness and refinement of a petrol. Or in other words, one step away from turning water into wine... 

Mazda is calling the process Spark Controlled Compression Ignition (SPCCI), and the extreme pressures required to make it all happen are created by higher static compression ratio (but less than a typical diesel), much higher fuel pressure and boosted air pressure entering the combustion chamber. 

Key to managing all these heightened parameters (and the very technological advancement that makes it all possible) is an ultra sensitive in-cylinder pressure sensor that has been developed specifically for this task. 

Delivering the boosted air pressure is a Roots-type supercharger - or what Mazda describes as a high-response air supply - which was chosen over other air pump designs like a turbocharger or the Miller-cycle supercharger previously used in Eunos models because of its instantaneous boost delivery and breadth of efficiency.

Speaking of breadth of efficiency, perhaps the biggest plus for average motorists is that the engine’s efficiency zone has multiplied, meaning the difference between city and highway consumption, leadfoot drivers and my Dad, heavy and empty loads etc will be far less than a typical petrol engine.

This all represents a continuation of core principles we’ve seen from the start of Mazda’s Skyactiv era. That is, to make an existing engine type work better under everyday driving conditions rather than targeting outright performance.

The Skyactiv-X era starts with a 2.0-litre based on the regular Skyactiv-G engine, with the same 1998cc capacity. Other capacities are planned, with the eventual reborn rotary looking increasingly Skyactiv-X along with a straight-six version for a new CX-9 in a couple of years. Smaller versions are unlikely due to the economies of scale involved with such technology in a smaller and therefore cheaper car. 

Mazda is making two versions of the Skyactiv-X 2.0-litre for now, one with 16.3:1 compression designed for Europe that favours Premium unleaded petrol, and one 15:1 version aimed at the US with their abundance of lower grade unleaded. 

Unlike conventional engines, it’s the lower compression version that will deliver the biggest benefits, because Skyactiv-X relies on the usually “bad thing” pinging to do its best. 

We’re set to get the Euro-spec one in Australia, which unfortunately means we won’t quite be getting the very best Skyactiv tech again.

The Euro-spec engine puts out 132kW at 6000rpm and 224Nm from just 3000rpm, which on paper sounds about halfway between the existing Skyactiv-G 114kW/200Nm 2.0-litre and 139kW/252Nm 2.5-litre petrol engines.

The engine also incorporates a mild hybrid system, but don't be confused by the H-word, there's no electric drive element. It simply means its got a cleaver alternator that only engages when needed and on deceleration to reduce efficiency-sapping drivetrain friction,

Pop the bonnet and you’re confronted by the biggest engine cover you’ve ever seen, but unlike most, this one is equipped with labeled latches that encourage you to have a look underneath. This encouragement continues with a clever little retention hook to hold the cover up against the bonnet while you’re poking around.

Unless you’re a Mazda engineer you’re likely to be baffled by the array of hoses, ducts and wiring, but you might get a kick out of spotting the supercharger.

There’s less to be said for the transmissions though, with versions of the existing six speed manual and torque converter automatics deemed up to the task, with the new engine’s increased efficiency zone negating any increase to the ratio count. The ratios have been adjusted to suit the new output characteristics, and while the ratios are yet to be published, there’s a narrower spread across the six with what feels to be taller first and sixth gears.


Infiniti Q307/10

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.

Fuel consumption

Mazda3

All this hooha about fuel savings, and Mazda is yet to confirm an actual figure for Australia. We do know the hatch is rated at 4.5L/100km in manual and 5.3L/100km in auto according to the NEDC, which is historically close to the figures generated by the ADR 81/02 test we go by in Australia. 

If it comes close to matching the NEDC figure it will be a win, sitting comfortably under the 6.4L/100km (manual) and 6.2L/100km (auto) figures currently applied to the Skyactiv-G 2.0-litre Mazda3 hatch

While the Australian-spec Skyactiv-X engine is expected to align with Europe rather than the US, and therefore be tuned to deal with Premium 95 RON unleaded, it’s still unclear if it will accept the cheaper Regular 91 RON unleaded.


Infiniti Q306/10

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.

Driving

Mazda3

What’s probably most amazing about Skyactiv-X is that you can’t really tell there’s anything special going on under the bonnet. 

Push the start button and it gets going like any other petrol Mazda, although perhaps quieter. 

Move off from rest and there’s no significant difference to the way it feels. 

When I drove the prototype version of this drivetrain, there was a slight pinging under light throttle as it transitioned from spark to compression ignition, but I’m pleased to confirm that the extra two years of calibration has tuned this down to the tiniest occasional diesel sound, and it all feels a bit like a smooth diesel that’s more responsive than you expect.

The European-spec Skyactiv-X 2.0-litre’s outputs suggest it should be closer to the existing 2.5-litre in terms of performance, but in reality it feels closer to the 2.0 litre.

My perception is likely to be clouded by the Skyactiv-X’s specific transmission gearing, but it could also be because it’s able to do the same job with less revs and therefore not sound like it’s working so hard. 

First gear feels quite tall with either transmission, and we also found the auto and manual were only sitting on 3500rpm in sixth at 160km/h on the Autobahn. 

Mazda doesn’t specify performance figures, so it would be handy to put all three alongside each other from a standing start. But then, that’s not what Skyactiv-X is all about, it’s more about performing better under light throttle and incidental bursts of acceleration. 

We can’t wait to put it to the test over some hilly terrain and familiar territory when it hits Australia early next year.


Infiniti Q307/10

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.

Safety

Mazda3

The existing Mazda3’s maximum five-star ANCAP safety rating will almost certainly be carried over, and the high level of safety gear fitted to the existing G25 Astina is also likely to be matched. 

This means front and rear airbag coverage, front and rear AEB, front and rear cross-traffic alerts, lane keeping assistance and blind-spot monitoring


Infiniti Q307/10

The Q30 scores some decent active safety goodies alongside the usual refinements. Active safety items include auto emergency braking (AEB) with forward collision warning, blind spot monitoring (BSM), lane departure warning (LDW) and active cruise control.

There’s also Nissan’s signature ‘Around View Monitor’ 360-degree reversing camera which sounds more useful than it is. Thankfully there is also a standard reversing camera.

The Q30 carries a maximum five-star ANCAP safety rating as of 2015 but has not been tested to the more demanding 2019 standards.

The rear seats also benefit from two sets of ISOFIX child seat mounting points

As previously mentioned, there’s no spare wheel in the Q30 Sport, so best of luck with the inflator kit if you end up with a flat in the outback.

Ownership

Mazda3

Service pricing is also yet to be confirmed, but Mazda engine development boss Eiji Nakai assures CarsGuide that the new engine will not need servicing more frequently or cost any more to service than existing Skyactiv-G engines.  

So expect the same 12month/10,000km intervals, with five year/50,000km capped servicing plan totalling just under $2000 over that period.  

Like all new Mazdas, the recently upgraded five-year, unlimited kilometre warranty will apply to the 3 Skyactiv-X. 


Infiniti Q308/10

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.
