Subaru WRX vs Infiniti Q50

What's the difference?

The new-generation Subaru WRX is a more accomplished, complete and mature car than ever before. If all of that sounds good to you, you’re going to love it - but I’m also totally going to understand if that would put you off, because it isn’t necessarily the same sort of car we’ve come to expect it should be.

But as the latest example of the breed, the WRX - especially as a sedan - is an engaging, fun car to drive. I just think the wagon would ultimately prove a lot easier to live with.

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

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.

You are going to make up your own mind about the look of the Rex. Let me just say this - don’t judge it by the pictures. It looks a lot more, er, agreeable in person. 

I’ll admit it - I was a bit uncertain about whether I would like it. I saw the pictures online and thought it looked a bit awkward. Those squinty headlights, the hexagonal wheel arches, the tapered rear quarter panels and small tail-lights… All of that makes it a bit hard to pick a “good” angle of the car. 

But in person it is a more cohesive piece of automotive design than it might appear at first glance. And look, the choice by Subaru to fit the WRX with the more aggressive looking lower body kit/rugged plastic finishes to the sedan, rather than the wagon, might seem weird to you.

But the brand insists the decision was made because the WRX sedan is more aimed at those who want the more angry look, while the wagon is more aimed at parents and family buyers.

Now, look, I’m a parent, and a potential buyer of a WRX wagon, and I’m frustrated Subaru doesn’t have a wagon with that lower body effect package. It looks narrower and less purposeful on the road as a result, and there’s even more reason for that - the wagon is narrower in the body, with skinnier front and rear guards.

You might be fine with the look of the wagon, compared to the sedan. But I think it would have benefited from less of the Levorg look, and more of the real Rexxy raucousness the sedan gets.

Now, Subaru has said it might consider customer feedback if there’s enough customer demand for a more macho wagon. And hey, the brand has a history of listening to customers and making the cars more appealing as the generation evolves - think about the third-gen WRX which launched with a narrow body but soon fattened up to look meaner…

Other notes on the design: the WRX wagon has different wheels, which are fitted with narrower, less aggressive tyres - it runs Yokohama Blue Earth GT tyres in 225/45/18 size, while the sedan, in keeping with its more intentful bent, runs far superior Dunlop SP Sport Maxx 245/40/18 tread. As a result, the wagon has a narrower front track (1550mm vs 1560mm) and rear track (1545mm vs 1570mm).

I’d love to see a more hardcore looking WRX wagon. Tell me if you agree or disagree in the comments below.

For context, here are the dimensions of the new WRX in sedan and wagon body styles:

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.

Obviously with a proper station wagon as part of the range now, it’s a much more practical WRX than we’ve ever seen before. But that doesn’t mean the sedan is impractical - rather, both are really quite well packaged and thought out for the most part.

Let’s start at the back, with the boot space. Cargo volume for the wagon is 492 litres with seats up and 902L with the back seats folded down (and 1430L to the ceiling). The cargo capacity of the sedan is 411L (RS and tS) to 414L (base model).

Hopefully we’ll get a chance to see how they fare with the CarsGuide luggage and / or a pram soon, but the boot openings for both versions are big and the load lips easy enough to contend with. All models have a space-saver spare wheel, too.

Back seat space is good for anyone who isn’t much taller than me. I’m 182cm (6’0”) and found my head was almost brushing the ceiling in the sedan, but I had a bit more head room in the wagon. Leg room with the driver’s seat set for me was good, and the toe room was only just adequate (I’ve got pretty big feet). 

Storage in the back is okay, with map pockets, bottle holders in the doors, and a flip-down armrest with cup holders. 

Parents will appreciate the ISOFIX child seat anchor points in the outboard seats, three top-tether hooks, and adjustable air-vents in all grades - so long as you buy an automatic model (manual versions miss out on rear directional air vents). The top two variants also have heated outboard seats and rear USB ports to keep occupants of all ages happy.

Up front the space is good, with a roomy feeling cabin courtesy of big windows and thin windscreen pillars.

The dashboard is dominated by that large 11.6-inch touchscreen, and it looks typically bold and colourful from Subaru. It’s mostly a really usable screen, with some hard buttons for the dual-zone temperature settings, demister, and volume and tuning knobs as well. The button that’s missing that I found myself cursing was air-con recirculation - it’s instead two touchscreen presses away.

There’s the requisite smartphone mirroring tech with wired Apple CarPlay and Android Auto, and the top models have sat nav. The top two specs also have a CD player hidden in the centre console bin, which is odd - but maybe the customer who appreciates built-in nav also likes CDs still… what was I saying about this car appealing to an older demographic…?

Storage is okay up front, with bottle holders in the doors, cup holders between the seats, that centre console bin, and a good glovebox. But a lack of wireless smartphone charging is a disappointment, and the section in front of the gear selector is too small for most smartphones.

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.

Gone is the old 2.0-litre engine of the previous WRX, and in its place is a 2.4-litre turbo-petrol four-cylinder ‘Boxer’ horizontally-opposed motor, with a power bump for this generation.

It now pushes out 202kW of power (at 5600rpm) and 350Nm of torque (from 2000-5200rpm), which represents a modest 5kW increase and the torque figure is dead on what it used to be.

You might be scratching your head at that, thinking Subaru has somehow made a mistake. The engine has 20 per cent greater displacement, but yet no significant difference in terms of the outputs? 

I questioned the brand’s boss and engineers about this, and they said “you don’t drive a spec sheet”. That is to say, the usability and drivability of the new engine is where you notice the more linear delivery of the torque, so admittedly, it’s not a wow-factor moment … until you drive the car.

There is a choice of a six-speed manual gearbox (sedan only), or a continuously variable transmission if you choose the wagon or one of the auto variants. Subaru insists it’s not like the CVTs of old, and in fact insists upon calling this gearbox the Subaru Performance Transmission. It has paddle shifters and throttle blipping, and eight ‘ratios’ available, with stepped ‘shifts’ as you accelerate decelerate.

It still sends power to all four wheels using Subaru’s symmetrical all-wheel drive system - manual versions come with a locking centre diff and viscous limited slip diff, where CVT models run a variable torque distribution system.

If you’re wondering, the 0-100km/h time for the manual is 6.0 seconds (identical to the last WRX) and the auto is 6.1 seconds (was 6.3). The auto figure is for both sedan and wagon.

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.

What price do you pay for WRX levels of performance when it comes to the pump? That’ll depend on the transmission you choose.

The automatic versions are better on the official combined cycle, with a stated figure of 8.5 litres per 100 kilometres. Choose the manual sedan and that figure jumps to 9.9L/100km.

On the test loop for the launch - which was hardly what I’d call “regular roads with a normal driving manner” - I saw 13.4L/100km indicated on the dashboard of the manual sedan, and an impressive 9.8L/100km for the auto wagon.

All models have a thirst for the good stuff, though, with 95RON premium unleaded required.

Fuel tank size is decent at 63 litres, so even if you’re driving it pretty hard you should be able to get more than 450km to a tank. 

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.

If you’ve scrolled down past all the other sections of this review to the driving part, I understand who you are. You’re the sort of person who actually cares about how a WRX drives – and the good news is that his new generation model drives very, very well. Well, actually, that depends on what you define as a good drive.

If you are after the immature, extremely enjoyable edge-of-your-seat experience that we’ve come to expect from the WRX, then you might think this new generation model has gone soft. And in some ways it has. 

The wagon, for instance, has a different suspension tune to the sedan. And it is indeed softer – and that’s intentional. Subaru says the buyer type for the Sportswagon is one who expects a level of comfort and ease of use that isn’t necessarily high on the priority list of the customer looking at the sedan.

As such, the sedan model has a more rigid suspension setup with stiffer springs and firmer dampers to ensure that the boy/girl racer is still appeased by the drive experience. And in the sedan you do feel a lot more of the road surface below you, with a firmer, more unapologetic ride. Where as in the wagon it is more disciplined and comfortable in almost every single situation.

The difficult bit is that the wagon in top-spec guise has even more intent to its suspension, because it is offered with the adaptive chassis control system. That means that it rides as firmly as the sedan when it’s in its sportiest drive mode setting. So, if you are after a more aggressive drive and you want a station wagon version of the WRX, then unfortunately you’re going to have to opt for the top spec wagon. That’ll leave some customers upset, because the extra $10,000 may not be easy to come by.

You need to consider that the tyre package is different between the two body styles as well. Even in the top-spec version of the wagon, you get a less aggressive tyre, and that means that it doesn’t have the same level of aggression in corners and isn’t as grippy, either. The easy solution in my mind would be to select the wagon but see if I could option a set of the sedan's wheels and tyres to improve the drivability and grip in the corners.

That isn’t to say that there isn’t enough grip, just that you can feel the wagon shimmy more in tight corners than is noticeable in the sedan, which has a significantly more sticky road presence. The Dunlops do it justice. The Yokohamas? Not so much.

The steering in both models is quite light and quite darty, and while I wouldn’t say that it’s the best steering of any car in its class, it does seem to be an improvement over the existing model. The drive modes can affect the way the steering behaves, and if you do happen to choose the top spec tS version then you can individually adjust the steering (as well as the suspension, power train, air conditioning, and safety systems). Even so, in the wagon the steering is still more likely to exhibit a bit of push-on understeer in tighter, faster bends. Not as evident in the sedan.

What about the elephant in the room then – it’s a bigger engine but with not a big power increase and has zero per cent torque adjustment over the existing model.

It is a better engine than before – like I said, it lacks that whip-crack personality of the old one, and it has removed a bit of the guesswork as to when you’ll be able to get the turbo to sing the tune that you wanted to. But, it is more linear in the way that it builds speed, and while it isn’t as visceral experience (a sports exhaust option would definitely be welcome, Subaru Australia!), it is a more refined and easy car to drive fast.

The other elephant in the room (yes it’s a big room) is the CVT automatic. This isn’t a new transmission – the last WRX auto had a CVT – but this one has been significantly reworked for a more aggressive characteristic and it is noticeably better. I wouldn’t say that it’s as technically pleasing as a dual-clutch automatic, especially in spirited driving, but it is definitely well suited to the character of the new car.

The auto does have paddle shifters so you can take matters into your own hands, and Subaru boasts that the up- and down-shift response times have been significantly improved. However, I didn’t like that the paddle shifters still overruled me in some situations - I felt like it took a bit of control out of my hands (no doubt in the name of mechanical sympathy, but even so, this is a sports car, right?).

The manual version remains a pick for those who really want to drive their WRX as a WRX ought to be driven. It’s the most engaging of the drivetrain options, and the shift action has been improved over the last model to offer a quicker feel between the gates, and the clutch action is nicely weighted as well. It is a serious shame that Subaru has missed the opportunity to sell a manual Sportswagon version of the WRX, and I sincerely hope that the brand rethinks that strategy at some point in the future. I know that for potential customers like myself, that would make the car even more appealing as a station wagon.

So, in summary, the fifth generation WRX is a more mature and high-tech drive experience than ever before. That comes at the expense of the larrikin nature of the earlier versions – but it isn’t necessarily a bad thing if you ask me.

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.

Subaru offers a five year/unlimited kilometre warranty covering the car, but just be aware that if you drive your car on the track, you might void that. Subaru says it has no plans to follow the lead of Hyundai N to cover track driving, but insists the brand will back its customers. 

Either way, the warranty cover is par for the course these days, and roadside assistance is included for one year from purchase. Other rivals offer years more coverage.

What has improved for this generation of WRX is the servicing situation.

There is capped price servicing for five years or 75,000km, meaning the intervals are finally set at 12 months/15,000km - no longer the pesky six-month/10,000km maintenance schedule of the previous model.

It depends on whether you choose manual or auto as to what price you’ll pay for maintenance, but there’s not a whole lot in it. The six-speed manual versions average $487 per annum over the five-year capped price period, while the auto versions are a little more affordable to maintain, at an annual average of $473.

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.
