Infiniti Q30 vs Hyundai I30

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.

Big boots to fill? The Hyundai i30 Sedan N stomps its authority with charming confidence and admirable talent. It’s hard to believe one of the biggest challengers to the i30 N hatch comes from its oddly-styled booted cousin. It’s just as thrilling, immersive, enjoyable and easy.

Which means that, if you’re in the market for a performance hot-hatch, it’s time for the sedan version to step into the limelight and be on your shortlist. It’s another N superstar.

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.

Now, with hot hatches, more usually means less, with spoilers quite literally living up to their name by blighting an otherwise clean and attractive design. For some, anyway. Under the radar and all that.

But the attention-crazy (CN7) i30 Sedan – known otherwise as the seventh-generation Elantra pretty much most other places around the world – seems like the work of a protractor-brandishing origamian who would not down pencil and stop.

Which means that, in the N’s case, more might actually be more, because all the racy extras enhance the appearance of a very distinctively/divisively-designed sedan.

The blacked-out bumper treatment, red brake calipers, side skirts and handsome alloys draw the eyes away from the odd creases and angles that define the i30 Sedan.

The result is a striking four-door fastback that comes into its own. One might suspect the original drawings were of a slammed-down N, with the overtly sporty stuff removed for the necessary lesser grades that most people end up buying.

Which would be a case of less being less!

Anyway, let’s check out the interior.

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…

Germany's small hot-sedan rivals would struggle to match the i30 Sedan N’s sheer practicality.

Running on a newer-generation architecture also shared with the latest Hyundai Kona, the result is a substantially larger, longer and wider proposition than the 2017-vintage i30 N hatch.

Upshot? The driver and passenger have plenty of space to stretch out in, within a palpably more contemporary cabin than presented in the five-door version. It feels like a car from the next size and decade up.

Being the i30 flagship, the N Premium’s dashboard is also dressed up to look suitably upmarket, angled towards the driver and offering twin 10.25-inch screens, with N-specific configurable instrumentation right ahead of the driver. Blue-stitched leather trim and darker cabin elements also set a racier ambience.

Predictably, there’s a comprehensive performance monitor within the touchscreen with all sorts of vehicle and driving data, including a lap timer. Clever if distracting. You might also take note of the big red button under one of the steering-wheel spokes, cringingly labelled NGS for ‘N Grin Shift’.

It brings a modest 7.0kW power boost, lasting only 20 seconds. Great for instant overtaking oomph, presumably.

Speaking of fast driving, lowered sports seats provide sufficient bracing through tight corners and extra ceiling clearance for helmets, while feeling sumptuously supportive the rest of the time. They're quite terrific.

Beyond these, all the regular sensible features found in more-humdrum i30 Sedans – an excellent driving position, ample ventilation, decipherable controls and stacks of useful storage – are also present.

The same applies across the generous back seat area, which lacks nothing for expected amenities to help keep kids of all ages safe, comfy, hydrated, ventilated and connected, while the N’s slightly-smaller boot (down 10 litres over the regular i30 Sedan) is still large enough for most needs at 464L. Blame the chassis stiffness brace back there.

Meanwhile, a space-saver spare lives underneath the wide, flat floor.

Complaints? The longitudinal buttress that runs along the left side of the centre console by the front passenger seat can constrict knee movement. Driver rear vision is poor, while that sloping back-door aperture makes getting in and out a head-banging affair for taller or bouffant-wearing folk.

Otherwise, the i30 Sedan N boasts a well-resolved cabin.

Does it ever!

Regardless of whether we’re talking about a manual or auto, the facelifted i30 Sedan N for 2024 is only available in the one Premium grade, kicking off from $52,000, before on-road costs.

And though now costing a bit more than before, if it’s a booted hot-hatch experience you seek, then this Hyundai has few rivals. And all are all-wheel drive and not front-wheel drive.

The most obvious is the excellent, if slightly less-powerful, Subaru WRX, which – from just $45,990 for the manual – must be considered an incredible bargain. But the Sport auto version for $4000 extra more-closely mirrors the Hyundai’s specification.

After that… there’s Germany. Consider the Mercedes-AMG A35 sedan, but that represents a near-$40K jump. Plus, you’re also approaching $90K before you can get the Merc’s compatriot competitors – Audi’s sleek S3 quattro and BMW's M235i xDrive Gran Coupe – on the road.

This, then, leaves just the WRX as the Hyundai’s sole affordable four-door sedan alternative for hatch-averse buyers.

So, what’s changed in the i30 Sedan N for 2024?

Along with new LED lights featuring Hyundai’s now-signature full-width light bar, it gains new bumpers and alloys, a strengthened body structure, an array of detailed steering and suspension modifications, upgraded driver-assist safety tech and updated multimedia including USB-C ports.

Note, too, the arrival of real-time connected car services Hyundai calls 'Bluelink' that can locate your car or notify emergency services automatically if you’ve had a prang, among other handy things.

These come on top of all the regular N gear, like the striking body kit, electronically controlled suspension, mechanical limited-slip differential (LSD), bespoke performance driving modes, bigger ventilated brake package and special Michelin Pilot Sport tyres.

Premium also heralds the usual expected luxuries, such as adaptive cruise control, heated and vented sports front seats, leather upholstery, dual-zone climate control, ambient lighting, 19-inch alloys and pretty much all of the electronic driver-assist tech in Hyundai's cupboard. See the safety section below for an expanded explanation.

The only options are a $2000 sunroof and $595 premium paint.

That’s all pretty compelling value-for-money, especially for a car this size… and abilities. More on that later.

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.

Make no mistake. Under the bonnet beats the absolute heart and soul of the Hyundai i30 Sedan N.

The engine carries over from before – a 1998cc 2.0-litre turbocharged four-cylinder direct-injection unit, making 206kW of power at 6000rpm and 392Nm of torque between just 2100 and 4700rpm.

Tipping the scales at 1475kg, the resulting power-to-weight ratio is an impressive 140kW/tonne. And, don’t forget, pressing the N Grin Shift unleashes an extra bit of power, bumping the total up to 213kW for a 20-second burst.

The 0-100km/h sprint time takes 5.3 seconds, on the way to a 250km/h top speed.

Refreshingly, traditionalists can still choose a six-speed manual (albeit with a rev-matching function), or eight-speed wet-type DCT dual-clutch auto transmission, and both drive the front wheels via an electro-mechanical limited-slip differential.

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.

The i30 N DCT’s official combined average consumption is 8.3 litres per 100km, for a carbon dioxide emissions rating of 194g/km.

Around town, that consumption figure shoots up to 11.8L, and drops to 6.3L outside of urban areas. Add 0.2L apiece for the less-efficient (but more-engaging) manual version.

Filling the 47L tank, with 95 RON premium unleaded petrol, you could exceed 565km between refills on average.

With a combination of gentle highway schlepping and blasting through the hills around the fast Murray River-area rural roads, our trip computer indicated a commendable 10L/100km – given this car’s 250km/h performance.

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.

Out about the hilly roads around Albury/Wodonga, the i30 Sedan N feels in its absolute element. The mixture of long open straights and tight corners really show off Hyundai’s incredible chassis tuning capabilities.

i30 Sedan N improvements for 2024 include brakes with better cooling and resistance to fade, stronger engine mounts for improved agility, more insulation, reduced vibrations, upgraded steering components for even more-precise handling and tweaks to the stability control system for more-effective operation.

Suspension is by McPherson-style struts up front and a multi-link rear-end arrangement.

Aided by an active variable exhaust note (which is quite nicely applied), the 2.0-litre four-pot twin-scroll turbo has a deep set of lungs, providing a decent wad of torque as it revs out fast and freely to its 6000rpm red-line. As you might expect, this is deceptively rapid.

Whether driving the solid and well-oiled six-speed manual – surely one of the best in the business and truly a great thing – or super-slick eight-speed DCT, there’s a delightful amount of muscle and speed for the money.

We’re also fans of the steering’s poise and response, resulting in hunkered-down handling that belies this car’s substantial length and width, backed up by lots of feel and feedback.

Throw in delightfully strong and effective braking, and the i30 N is incredibly alert and agile for something so big.

The trade-off of all this athleticism is a consistently firm – though not harsh – ride, as well as some road and tyre-noise intrusion when cruising comfortably along the highway.

As an everyday commuting proposition, the i30 Sedan N is right on the money.

Out on the racetrack, however, it's like on something a little bit more illicit, for things really start coming alive, with the N’s polished chassis set up revealing a satisfyingly vivid bandwidth of capability.

In 'Normal' mode, the front end feels reassuringly planted with minimal understeer, while the rear possesses a playful lightness that allows for progressive back-end lift-off if desired.

The i30 is so exquisitely tuned and pliable it makes amateurs feel like professionals.

Select 'N' mode and the electronic limiters loosen, for proper oversteer fun if that’s your thing, controlled and reeled right back in by meaty, confidence-boosting steering, providing improbably fluent handling for a sedan this size.

Slicing through tight bends and long arcs alike, the Hyundai’s sheer dynamic precision, consistency and discipline are deeply impressive. And intoxicating. We didn’t want to stop.

It may not look like a hot hatch in the prime of its life, but the i30 Sedan N sure behaves like one. And all for just $52K. Cheers, Hyundai!

As with all i30 Sedans, the N does not score an ANCAP rating because it's not available in Europe. The hatch, on the other hand, managed a maximum five stars back in 2017.

Hyundai is pretty confident the sedan would score highly, too, due to a raft of standard driver-assist safety items, including Hyundai’s 'Forward Collision Avoidance Assist' (version 1.5) featuring AEB with pedestrian and cyclist detection, blind-spot monitoring, safe-exit warning and rear cross-traffic alert.

There is no speed operation data for the AEB and lane-assistance systems at this time.

As well, the N owner also scores driver-attention warning, intelligent speed limit assist, adaptive cruise control with full stop/go, rear occupant alert, six airbags, electronic stability control, anti-lock brakes with 'Brake Assist' and electronic brake-force distribution, tyre pressure monitors, rear parking sensors, a rear view camera, dusk-sensing headlights, auto high beams, rain-sensing wipers and front/rear parking sensors.

As with all i30 Sedans, the N’s back seat comes with two ISOFIX points as well as a trio of top tethers for straps.

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.

The i30 Sedan N brings a five-year/unlimited kilometre warranty, as well as one year of roadside assistance.

Service intervals are at 12-months or 10,000km (not at every 15,000km like the regular i30 Sedan), with service pricing published on Hyundai’s website.

Over the first five years, the standard scheduled cost is $1795, or an average of under $360 annually.
