Summary

Subaru WRX

For many folks around my age, the Subaru WRX holds a special place in the heart.

This is because those of us born from the late ‘80s to early ‘90s are the so-called “PlayStation generation.” Growing up at a time where videogames bridged the gap from 2D to 3D leads to a lot of imprinted memories, a lot of digital firsts, which wowed and inspired, and a lot of rapid-fire nostalgia as hardware advancements left once-thriving game franchises in the dust. 

It was also high time for the World Rally Championship's well-regarded Group A rally category, which forced manufacturers to make cars much closer to their production counterparts. It was frequently dominated by none other than the Subaru WRX.

Combine these two worlds and you end up with a lot of kids feeling like they could do anything in Subaru’s newfound performance hero from the comfort of their bedrooms, many of whom would go on to buy a second-hand one to slap P plates on as soon as they could.

It was a perfect storm and made the WRX the right car at the right time to put a previously small-time brand well and truly on the performance map.

The question with this test is: Should those kids, now in their late 20s or 30s, still be considering Subaru’s halo car? Or, now that it’s the oldest product in Subaru’s catalogue, should they wait for the imminent reveal of the new one? Read on to find out.

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.

Verdict

Subaru WRX7.5/10

Although it's now the oldest car in Subaru’s catalogue, there’s nothing really quite like the WRX on the market. This is a car which is true to its roots, a rugged performance stalwart that comes with dollops of fun and compromise in equal measure. 

Thanks to Subaru’s updates over the years, it’s fared better than some when it comes to technology and safety, but I’d still implore you to pick the manual to truly experience this car as nature intended.


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.

Design

Subaru WRX7/10

I think Subaru was gunning for subtlety with the non-STi WRX. For a performance car, the design is a little sedate, with the WRX looking perhaps a little  conservative to really stand apart from its Impreza sedan sibling, despite diverging from it some years ago.

There’s no mistaking the rally profile of the full-fat STi, with its huge wing and even bigger wheels, but here in the WRX premium it’s all a little toned down. Still, fans will love the absurd bonnet scoop, angry-looking alloys and quad exhaust. It’s stanced out a little by some flared bodywork, but the tiny lip spoiler at the back robs it of a bit of street cred. Perhaps it's to encourage you into the significantly more expensive STi…

Despite its relative age, though, the WRX still fits into Subaru’s lineup nicely. It has all the hallmarks; the small grille, the angled LED headlights, and the signature tall profile. The chunkiness is all there, too, both on the outside, with its flared bodywork and exaggerated scoop, and on the inside, with thick leather clad seat trim, and a chunky, satisfying steering wheel.

The abundance of red lighting in the dash cluster is reminiscent of the heyday of Japanese performance cars of years past, and while it’s not as plush on the inside as Subaru’s newer products, it’s not disappointing either, with nice use of soft trims.

The plethora of screens feels unnecessary, and the 7.0-inch multimedia unit is feeling very small now, compared to most more recent cars. At least the software has been updated since 2018 to have the more recent system used in the Impreza, Forester, and Outback. It’s simple and easy to use.

Compared to those Subarus, though, the WRX’s interior is feeling a little tired. It’s a bit small, and things like the CD drive and nastier plastic trims smattered around remind of days past for Subaru. It's a good thing the new WRX is coming soon.


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. 

Practicality

Subaru WRX7/10

Compared to the more forward-thinking designs in Subaru Global Platfrom vehicles, the WRX is feeling a little claustrophobic on the inside. Still, you could do much worse in a performance car.

Front passengers get nicely trimmed bucket-style seats with good side bolstering. Like a lot of Subarus, the seating position isn’t exactly sporty. You sit quite high, and for someone my 182cm height, it feels as though you’re peering down over the bonnet a little. Aside from that, height adjustability is pretty good from the electric seat, and there is a small bottle holder in the door, plus dual cupholders in the centre, a small centre-console box, and a small tray under the climate unit.

Overall, the dark trims in here conspire to make the WRX’s cabin feel a bit tight. This continues for rear passengers. The WRX really is a small sedan and room isn’t great for me behind my own driving position, with my knees touching the front seat. I have to duck a little to get under the sedan’s roofline to get in, and while the decent  trim continues, the seat feels a little high and flat.

Rear passengers get pockets on the backs of the front seats, a drop-down armrest with two cupholders, and a decent bottle holder in the doors. There are no adjustable rear air vents or power outlets, however.

Being a sedan, the WRX has a rather deep boot, coming in at 450-litres (VDA). This rivals some mid-size SUVs, but it’s worth noting the space isn’t quite as usable, with a small loading aperture, and it’s a little tight when it comes to the available height. Still, it consumed our largest 124-litre CarsGuide suitcase with ample space to spare.


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. 

Price and features

Subaru WRX7/10

The WRX Premium auto tested for this review is a sort of mid-spec variant. Wearing an MSRP of $50,590, it sits above the standard WRX auto ($43,990), but below the more hard-core WRX STi ($52,940 – manual only).

When you look for rivals, it’s a harsh reminder of the distinct lack of small performance sedans in today’s market. You might consider Subaru’s hero against the front-drive Golf GTi (Auto -$47,190), Skoda Octavia RS (Sedan auto - $51,490), and Hyundai i30 N Performance (manual only - $42,910). There’s a more direct rival coming soon in the form of the i30 N Performance sedan, which will also be available with an eight-speed dual-clutch auto, so look out for that in the near future, too.

While it's now the oldest Subaru on sale by quite a margin, the WRX has been augmented in recent times to offer more up-to-date features.

Standard are mean-looking 18-inch alloys clad in skinny Dunlop Sport rubber, full LED lighting, Subaru’s typical assault of screens, including a smallish looking 7.0-inch multimedia touchscreen (mercifully with updated software since I last drove this car), a 3.5-inch multifunction display in the instrument cluster, and a 5.9-inch dash-top-mounted  display screen, digital radio, Apple CarPlay and Android Auto connectivity, a CD player (how quaint), leather-accented interior trim, eight-way adjustable power seat for the driver, heated seats for front passengers, dual-zone climate control, and privacy tint for the rear windows.

The continuously variable automatic makes up the majority of WRX sales, so I’m told, which is particularly disappointing to hear. Especially given it’s a $3200 jump over the manual, and tarnishes the drive experience. More on this in the Driving section.

The WRX also comes with a safety suite that is impressive for a car of its vintage, which we’ll look at in the Safety section. Getting on it may be, but the WRX is surprising in how well it holds its own on the value front.


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.

Engine & trans

Subaru WRX8/10

The WRX’s engine is a tuned-up version of Subaru’s signature horizontally opposed “boxer” four-cylinder. In this case it’s a 2.0-litre turbo unit (FA20) producing 197kW/350Nm, ample for a little sedan like this.

Disappointingly for me, our particular WRX premium was an automatic, and it’s not a great one. While most performance cars will drop in a lightning fast dual-clutch, or at least have the decency to offer a classic torque converter with clearly defined ratios, Subaru falls back on its rubbery continuously variable automatic, as derided in the rest of its mainstream range by enthusiasts.

We’ll explore this more in the Driving section of this review. It’s not as bad as you think it’s going to be, but it still doesn’t belong in a car like this.

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.

Fuel consumption

Subaru WRX8/10

Fuel consumption is likely to be at the bottom of your list of concerns when it comes to a small performance sedan, but on the official/combined testing cycle, this car will consume a claimed 8.6L/100km of mid-shelf 95RON unleaded.

Over our week of mostly urban testing, our car produced an unsurprising 11.2L/100km, which is actually under the official urban number of 11.8L/100km. Not bad for a performance car, really.

The WRX has a relatively large fuel tank for its size at 60-litres.


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.

Driving

Subaru WRX8/10

It truly pains me that this car is an automatic. Don’t get me wrong, I’m okay with an automatic performance car. Dual-clutch iterations of cars like the Golf R are great, but the WRX automatic is a CVT.

This transmission isn’t great in the brand’s regular range, let alone in a performance application, where snappy response and a predictable, linear riding out of the rev-range are really necessary to extract maximum enjoyment.

I was surprised to find the CVT isn’t as bad as I thought it would be. Perhaps through sheer torque, the WRX does hammer into its 2400rpm peak torque band rather quickly, for an immediately impressive 0-100km/h sprint of around six seconds, but it’s beyond this point where you’ll start to get dull, rubbery, and occasionally hesitant response from the accelerator. Not particularly appealing attributes when you’re carving up a few corners.

Handling-wise, the WRX is excellent with its robust all-wheel-drive system and firm-to-a-fault suspension. This makes it a true joy to fling around bends, with equally firm and rewarding steering giving you a truly organic and controlled handle on what’s going on at the wheels.

Subaru’s boxer engine gives the WRX a signature gruff sound under acceleration, with some turbo noise to boot, but with this particular transmission you won’t be getting the satisfying turbo blips you can extract with a swift kick of a clutch pedal in the manual.

Driving it around town every day is a little rough, with a brittle and busy ride, while the heavy steering will get on your nerves when you’re just trying to park the thing. 

The firm ride, large wheels, and slim tyres makes the cabin noisy at all speeds, and occasionally sends shockwaves through the front of the car if you’re unfortunate enough to hit a pothole. It’s hardly the most pleasant companion to have on a freeway.

Honestly, if you’re after an automatic performance car, there are better options out there both in terms of response and everyday comfort, although none are quite like a WRX. I’d implore you to pick the manual if you can, it’s a better, more engaging experience in every way.


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.

Safety

Subaru WRX8/10

In good news for the WRX, Subaru’s signature EyeSight suite is mostly present here, albeit a slightly older version than the one that appears in its newer products. Regardless, key active items include auto emergency braking (works to 85km/h with brake-light recognition), lane-departure warning with lane-keep assist, blind-spot monitoring with rear cross traffic alert, adaptive cruise control, and auto high beams.

It misses out on reverse auto braking from more modern Subarus but features active torque vectoring to add to the standard suite of electronic aids like traction, brake, and stability controls.

The WRX has a maximum five-star ANCAP safety rating, although it dates way back to 2014, well before active safety items were even considered.


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

Ownership

Subaru WRX7/10

Subaru offers a competitive five-year and unlimited-kilometre warranty promise.

Annoyingly, the WRX requires six-monthly or 12,500km service intervals, a hold-over from Subarus past. It’s not cheap, either, with each six-monthly visit costing between $319.54 and $819.43 (ouch) for the first 10 visits covering five years of ownership. It averages out to $916.81 per year for the first five years. These are numbers which rival some premium European options.


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.
