Infiniti Q30 vs Infiniti Q50

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.

The Q50 Red Sport is a premium sedan that's great value, with a cracker of an engine. While Infiniti has improved the ride and steering, it still feels to me that the engine is too powerful for the wheels and chassis to handle. But if you're looking for something of an untamed beast, this car could be for you. Just don't say we didn't warn you.

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.

The Q50 Red Sport looks cranky from front on, which I like in a car. Yes, the grille is simplistic and gaping, the nose is a bit bulbous, and sure, side on the car looks like a Lexus IS 350, but those rear haunches and the aggro body kit with its front splitter and boot lid spoiler make for an impressive looking four-door sedan.

The update brought restyled front and rear bumpers, those red brake calipers and the dark chrome 20-inch rims and new LED tail-lights.

Inside, the cabin is an asymmetrical paradise (or hell, if you're a bit OCD like me) full of sweeping lines, angles, as well as different textures and materials.

The red stitched quilted leather seats are an addition that came with the update, so is the new steering wheel and the ambient lighting.

The 'Sunstone Red' colour of our test car is also a new hue which looks a bit like Mazda's Soul Red. If red is not you, there are other colours – hope you like blue or white or black or grey because there's 'Iridium Blue', 'Midnight Black', 'Liquid Platinum', 'Graphite Shadow', 'Black Obsidian', 'Majestic White' and 'Pure White'.

The Q50 has similar dimensions to the IS 350: both are 1430mm tall, the Infiniti is 10mm wider at 1820mm,  120mm longer at 4800mm, and has a wheelbase that's 50mm longer at 2850mm.

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…

The Q50 Red Sport is a five-seat four-door sedan and is vastly more practical than its two-door Q60 Red Sport sister, in that I can actually sit in the back seat. The Q60's coupe styling looks amazing, but the sloping roofline means headroom is so severely limited that it reduces the rear seats to a place to throw your jacket.

True, I'm tall at 191cm, but in the Q50 Red Sport I can sit behind my driving position with legroom to spare and more than enough headroom.

Boot space is good at 500 litres, which is 20 litres more than the luggage capacity of the IS 350.

Storage throughout the cabin is good with two cup holders in the rear centre fold-down armrest, two more up front and bottle holders in all doors. A large centre console storage bin and another big storage area in front of the shifter are great for keeping junk under control and your valuables covered.

Maybe sit down for this next bit. The Q50 Red Sport lists for $79,900. Are you okay? Do you want a moment? Remember, though that only seems like a lot because it's not a Benz or a BMW. Truth is the value is pretty good – better than a German car of the equivalent size and grunt.

Look at the standard features list: 8.0-inch and 7.0-inch stacked touchscreens, the 16-speaker Bose 'Performance Series' stereo system, digital radio, road noise cancellation, sat nav, 360-degree camera, leather seats, power adjustable from sports seats, dual-zone climate control, proximity key, sunroof, auto wipers and adaptive LED headlights.

The 2017 update brought new standard features to the Red Sport including, red stitching on the seats and dash, quilted leather seats, new 19-inch alloy wheels and red brake calipers.

Don't forget that the bang-for-buck factor is strong with the Red Sport, too. In that nose is a twin-turbo V6 that makes almost as much grunt as the BMW M3 for about $100K less. Even the 340i, which Infiniti says is a Red Sport rival, is $10K more. Truth is though, the Lexus IS 350 is the real rival to the Q50 Red Sport.

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.

Inside the Q50 Red Sport's nose is a 3.0-litre twin-turbo V6 petrol engine and it is a beautiful thing. To me this car is piece of technologically sophisticated jewellery that cradles a precious gem that pumps out 298kW/475Nm.

But I have my concerns... you can read about those in the driving section.

Shifting gears is a seven-speed automatic which delivers drive to the rear wheels.

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.

Infiniti says the V6 petrol engine in the Q50 Red Sport should use 9.3L/100km if you're using it on a mix of highways, urban streets and country roads. We only had the Q60 Red Sport for 48 hours and after a couple of days of Sydney city commutes and a trip to the Royal National Park our trip computer was reporting 11.1L/100km.

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.

Perhaps the biggest complaint we had about the previous Q50 Red Sport, which launched in 2016, was that it felt as though the chassis wasn't up to the amount of grunt running through it, and those rear wheels struggled to transfer the oomph to the road without losing traction.

We experienced the same issue again in this new car. I was breaking traction, not just in 'Sport+' and 'Sport' modes, but in 'Standard' and 'Eco', too. That was happening without pushing it hard and with all electronic traction and stability aids on.

If I was 18 I'd declare to the world I'd found my dream car - something that always wants to 'light 'em up' given half a chance. But like that one mate who always gets into trouble on a night out it's only funny when you're young.

A truly great performance car is planted, balanced and able to deliver the grunt to the road effectively. The Nissan R35 GT-R is the perfect example – a brilliant piece of machinery, a weapon of a performance car and with a chassis matched perfectly to its engine.

And that could be the issue with Q50 Red Sport - that engine feels overpowered for the chassis, and wheel and tyre package.

We also felt the previous Q50 Red Sport's ride, with its constantly adapting 'Dynamic Digital Suspension', was overly busy. Infiniti says it has developed the suspension system further and it does feel as though the ride is more comfortable and composed.

Steering was another area that we weren't overly impressed with when we drove the previous car. Infiniti's 'Direct Adaptive Steering' (DAS) system is super sophisticated and was the first in the world not to have any mechanical connection between the steering wheel and the wheels – it's all electronic.

The new Q50 Red Sport uses the upgraded 'DAS 2' and while it feels better than before, it's only in Sport+ mode that it seems most natural and accurate.

The Q50 was given the maximum five-star ANCAP rating in 2014 and the amount of advanced safety equipment which comes standard on the Red Sport is impressive. There's AEB, that works forwards and when you're reversing, forward collision and blind spot warning, lane keeping assistance and moving object detection.

There are two ISOFIX points and two top tether anchor points in the back row, for child seats.

The Q60 Red Sport doesn't come with a spare tyre because the 245/40 R19 tyres are run flats, which means even after a puncture you should be able to keep driving for about 80km. Not ideal in Australia where distances are seriously vast.

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 Q50 Red Sport is covered by Infiniti's four year/unlimited kilometre warranty with servicing recommended every 12 months or 15,000km.

Infiniti has a scheduled servicing program which will cost $1283 (in total) for three years.
