Mazda 3 vs Subaru Impreza

What's the difference?

Given how effortlessly it traverses the mainstream and premium small car classes, the Mazda 3 might be the best value small car on the planet.

With racy styling, sports car handling, classy interior presentation and impressive, intelligent efficiency, there’s plenty to sink your teeth into here.

Poor rear vision, a dark back-seat area and smallish boot aside, it doesn’t have any glaring faults.

In a world overrun with SUVs, props to Mazda for evolving the small car so brilliantly to mask a half-decade of existence. Continuous improvements have made the 2024 G25 Evolve SP Vision an essential small car shortlist proposition, regardless of price.

The 2024 Impreza delivers on all the key things which have made the nameplate so well regarded for the last 30-odd years.

The issue is, buyer expectations have moved on. Hatchbacks need to do more than ever to compete with small SUVs, and with today’s fuel prices it’s far more valuable to offer hybrid rather than all-wheel drive.

This is why, despite the sixth-generation Impreza being a tidy high-tech offering with an admirable commitment to safety, I think it will ultimately continue to shrink its market share. This Impreza really is one for the fans.

How is it that the current Mazda 3 is already five years old? This hatchback is still stunning, the sort of car you look back at when walking away.

The shape is sleek and almost coupe-like, with a shark-like nose, cab-backward-style long bonnet, upswept shoulder line and a fastback silhouette.

More importantly, it’s the way the light dances across the sculptured sides that draw the eyes in. Bereft of clutter, it makes you wish all mainstream manufacturers had the courage to be so daring.

We’ve said it before – the 'BP'-generation Mazda 3 (Axela in Japan) is the brand’s boldest C-segment hatch since the 1993 'BA' 323 (Astina/Lantis/323F).

But there’s a price to pay for such timeless beauty…

Over the years the Impreza has changed in its design and intention so much.

Once known primarily for its sporty sedan variants, today’s Impreza is a far more contemporary hatchback, forgoing the once wagon-like shape for something with the traditional bubble silhouette to align with its rivals.

For better or worse, it also syncs up with the rest of Subaru’s range, with the brand’s current design language on full show, but it also barely evolves from the previous-generation version from the outside.

It trades the chunky square light fittings from the previous car for something a bit more refined this time around, with a similar look and feel to the WRX and Outback.

Inside also gets a similar fit-out to other Subarus in the range, complete with a raised centre console, shapely dash, and the same huge screen from the Crosstrek and Outback which dominates the space and helps simplify things compared to the busy interior and multiple screens of the previous car.

It’s a cosy space with chunky comfortable seats and the signature bumper car steering wheel is a stand-out bit of Subaru design.

Even the base car with its plastic trimmed wheel and basic cloth trims in the door is basic in an almost refreshing way, but unlike some rivals manages to be comfortable, too, thanks to soft trims for your elbows in the doors.

There is a price to pay for all this quasi-coupe styling flair, and that’s a comparatively snug-feeling interior, though you’d never call it cramped.

Actually, the Mazda 3 is no less spacious than most of its competition in all but one area, with enough room even for 200cm drivers, along with sufficient shoulder width and ceiling height to match.

If you’re really tall, maybe that missing sunroof isn’t such a bad thing, after all.

Sat so low-down on cushy, enveloping front seats that offer plenty of comfort and support, this is the anti-SUV. Maybe Mazda should have called this the MX-3.

Sporty and spot-on, the driving position is a laid-back affair, with an emphasis on better ergonomics, as emphasised by the thoughtful placement of switchgear that’s all within easy reach, ahead of a beautifully flowing and layered dash. Proudly Japanese in flavour, it brings to mind functional minimalism.

Drilling into some of the 3’s finer interior details, the analogue-look digital instrumentation is super-legible, ultra-classy and gorgeously lit at night. As previously mentioned, the dials and surrounding air vents are reminiscent of the later Porsche 944 and 968.

It’s not just all for the sake of aesthetics, either.

Yes, it’s lovely, but the thinned-rim three-spoke steering wheel feels great to grip, with nifty little paddle shifters that are a delight to prod.

Same goes for the physical volume knob and climate-control buttons, sidestepping the need to get distracted and frustrated by virtual sub-menus.

And having a conventional gear lever with old-school Tiptronic-style shifts suits the 3’s athletic vibe.

Plus, forward vision is A-OK, ventilation is faultless, storage is better than you might expect, and the fit and finish is as good if not better than any of this 3’s German premium opponents.

Out back, the split-fold rear backrest is set at a comfortable angle, the cushion is well padded, and you’re provided with USB ports, air vents, and an armrest with two cupholders. More thoughtfulness.

But while knee room is fair, rear headroom isn’t great if you’re tall or wear a beehive, as the falling ceiling line reveals.

Vision out is limited by that rising window line and fat pillars. Getting in and out of the back requires some contortionist moves. And the small windows mean it can be gloomier in the back than a Smiths album.

Finally, at just 295 litres, the 3’s cargo capacity is disappointing. Sure, it eclipses the Corolla hatch’s 217L cubby, but other rivals are far larger back there.

At least the floor is wide and flat and there are 60/40-split backrests for cabin access for longer items.

Note that a space-saver spare wheel lurks underneath. Mazda argues there’s always the closely-related CX-30 if you need (slightly) more space (317L).

Meanwhile, at the other end of the 3…

Living up to the adventure-ready Subaru promise, the Impreza's interior is quite functional.

Even though many controls have moved to the big central screen, there are individual buttons for temperature adjustment and a permanent touch function for fan speed on the lower third of the screen.

It would be nice to see a full set of physical buttons for climate functions, but this seems like a decent compromise.

Elsewhere there are large bottle holders in each door with a small accompanying pocket, two more rigid bottle holders in the centre console, a small tray behind them, and a huge armrest console box.

Under the multimedia screen there is a bay with a wireless phone charger, but like the Crosstrek, it is finished in a hard plastic material, which means your phone will easy slide around and out of the charging area in the corners, which seems like an oversight.

Adjustability is great, even in the base car, with flexible seats and a wide range of movement for the wheel, letting you easily find a suitable seating position. Width in the cabin is okay, but headroom is excellent.

The back seat offers a solid amount of room for myself behind my own seating position, at 182cm tall, but the middle position is no good for an adult thanks to the presence of a large raise in the floor to allow for the all-wheel drive system underneath.

Amenities for rear passengers are only okay in the base car, with a large bottle holder in the door and a further two in a drop-down centre armrest. There are no adjustable rear air vents or USB power outlets in the L, but outlets are added in the R and S.

Boot space is on the small side, with only 291 litres (VDA) on offer. The high floor means a limited amount of space with the luggage cover in place, although I was surprised to find we could fit the full three-piece CarsGuide luggage set once it was removed, so long as you’re okay not being able to see out the rear window.

Under the floor, the Impreza sports a space-saver spare wheel - a must-have for long-distance regional travellers.

Now in sixth-generation form, the 2024 Impreza range has been trimmed down to just one hatchback bodystyle and three trim levels - the base L, mid-spec R, and top-spec S.

True to Subaru form these variants are all priced quite close together, and the base L comes with pretty much all the kit you’ll need, with the R and S grades adding mainly luxuries to the equipment list.

Now starting from $31,490, before on-road costs, the Impreza is not as affordable as the previous-generation version, and while it manages to pack a relatively high level of standard equipment, some of its key rivals are a bit cheaper in a segment where every dollar matters.

For example, you can get into a hybrid version of Toyota’s Corolla (Ascent Sport Hybrid - $32,110) for similar money to the entry level 2.0L, the Kia Cerato can be had for under $30,000 (Cerato S Auto - $27,060) while the outgoing Hyundai i30 is significantly cheaper in its most basic trim level (i30 Auto - $26,000).

What might make you think twice is the Subaru’s standard all-wheel drive, where all of its rivals are front-wheel drive, but in an environment where fuel costs are high, I can understand why people would prefer to see a hybrid version instead.

Unlike the Impreza’s Crosstrek small SUV relation, there’s no ‘e-Boxer’ hybrid variant.

Still, standard equipment is high even on the base 2.0L. Included are 17-inch alloy wheels, LED headlights, a massive 11.6-inch multimedia touchscreen with wireless Apple CarPlay and Android Auto and you even get a matching wireless phone charger.

Elsewhere the base car gets cloth seats with manual adjustment, a plastic steering wheel, analogue instrument cluster with a small digital display, and importantly, the majority of Subaru’s very good active safety equipment is standard.

So, what do you get for stepping up the range? At $34,990, the 2.0R adds premium cloth seat trim, additional charging ports in the rear, eight-way power adjust for the driver, heated front seats, a leather steering wheel and shifter, steering responsive LED headlights, and LED fog lights.

At the top of the range, the $37,990 2.0S adds a 10-speaker audio system, built-in sat-nav, an electric sunroof, and synthetic leather seat trim.

The cabin tech, safety, and standard all-wheel drive are the real draws, but you have to want them. The Impreza isn’t the stellar value buy it once was.

When you think about it, shoehorning a big torquey engine in a light and agile small car is a recipe for fun. Ford did just that with the Escort RS2000 in the 1970s… and Mazda’s now an expert at it, too.

The engine in question is the G25, a 2.5-litre four-cylinder naturally aspirated twin-cam petrol engine, delivering 139kW of power at 6000rpm and 252Nm of torque at 4000rpm.

As this Evolve SP Vision hatch tips the scales at 1415kg, it makes for a healthy, and consequently very lively, power-to-weight ratio of over 98kW/tonne.

That’s if you decide to use all the available revs, which the six-speed torque-converter auto makes great use of.

Driving the front wheels, it offers a 'Sport' mode to extend the revs even more, which is keeping in line with this Mazda’s sporty character.

Less so is the company’s decision to ditch the old multi-link independent rear suspension system a few years back for a more prosaic torsion beam arrangement. We’ll get to how that affects ride and handling in a moment.

The Impreza is equipped with just one engine and transmission for its sixth-generation, a 2.0-litre (FB20) four-cylinder horizontally-opposed ‘boxer’ engine mated to a continuously variable automatic transmission, driving all four wheels via the brand’s signature ‘symmetrical’ permanent all-wheel drive system.

The FB series is a development of the successful EJ series engines which lasted from 1989-2021. This more recent engine has new material science, heads, and seals which have helped the brand push service intervals out to 12 months rather than six, and should address issues which the older engines developed over time.

Power is on-par, but not a stand-out in the segment, with peak outputs of 115kW/196Nm.

Mazda claims the G25 averages 6.6L/100km on the combined cycle… for a carbon-dioxide emissions rating of 154g/km. On a 51L tank, that gives a potential distance of over 940km!

Driven good and hard in our hands, we managed 7.5L/100km, which isn’t bad given the speed and conditions it was subjected to.

Plus, the Mazda’s happy on 91 RON 'standard' unleaded petrol.

One issue with having a non-turbo, non-hybrid 2.0-litre engine with all-wheel drive is relatively high fuel consumption. The Impreza has an official combined cycle fuel consumption figure of 7.5L/100km which is less than impressive in today’s market of hybrids and downsized turbocharged engines.

In my week of mostly stop-start city driving, the test example drank 11.1L/100km, which is disappointing.

Mercifully, it is capable of running on 91RON unleaded. For those who care, the CO2 output is officially 170g/km which is well above the 140g/km it would need to be at to avoid the wrath of incoming vehicle emissions regulations.

Ask yourself. What do you want from a new small car?

Since the first Familia of the early 1960s, Mazda’s been at it constantly, through the 1300 and 323 eras and into the modern age of the 3.

The Hiroshima brand knows its stuff. Space, practicality, comfort, ease, reliability and affordability. But a small car has to offer more, specifically in the way it makes the owner feel.

That’s why, while the Focuses, Lancers, Astras and Pulsars are gone, the 3’s still here. And it isn’t just the lush visuals inside and out that are, well, sensory-rich.

As older Alfa Romeo owners know, there’s something special about an engine that sounds alive, and the moment you push the 3’s starter, it purrs into life. That’s the first clue.

Slot the refreshingly old-school lever into Drive, and the G25 leaps into action, and, if you need it to, will keep pulling forward strongly, engine buzzing, like it’s on a mission.

That describes the torquey urge of this big 2.5L four, paired perfectly with the sensibly-geared auto.

We miss Mazda’s magnificent manual immensely, but the 3’s instant response reflects its favourable circa-100kW/tonne power-to-weight ratio.

And, as we’ve harped on in the past, the twin-cam unit’s extra oomph beyond 4000rpm delivers muscular high-speed responses akin to a good turbo – or a great old-school Alfa. You can keep your laggy dual-clutch transmissions, Europe.

Now, sweet, smooth and speedy performance is one thing, but having the chassis tuned with precise and fluid steering for tactile handling, and confident roadholding, backed by nuanced driver-assist and traction controls, are another.

There is a consistent and unifying control to the 3’s linear and forgiving dynamics, reminiscent of past masters like the Focus (and today’s brilliant Peugeot 308) that makes it a joy to drive enthusiastically through fast corners, with the knowledge that it won’t suddenly snap-oversteer and bite an unalert driver back.

For a Mazda, the ride is quiet enough, but there is still some droning transmitted through the cabin, via the Bridgestone Turanza (215/45) tyres, on coarse-chip bitumen surfaces.

And while suspension comfort is pretty impressive for the most part, larger bumps reveal the torsion beam’s limitations, as the car can occasionally thud over them in a way that we remember the multi-link rear end wouldn’t.

Anyway, what we’re saying is that, overall, the 3 Evolve SP Vision is an immersive and interactive driving experience that is right up there with the best of them.

Brawny performance, exquisite agility and a refinement that, collectively, have eluded every small Mazda in living memory until this generation’s 2019 debut. This 3’s right on the money. Still.

Have you driven a Subaru in the last 10 years? The drive experience here is pretty much uniform with the rest of the automaker’s range.

This means a lot of very appealing traits. For example, the new Impreza has a comfortable, compliant ride, really nicely weighted steering, and solid handling even on slippery surfaces courtesy of the all-wheel drive system.

The FB series engine also has a good bit of pull fairly early in the RPM range which makes it deceptively spritely, although power really hollows out the more you push it.

This makes it nice to drive around town, but less impressive when it comes to overtaking on the freeway.

This is reinforced by the continuously variable automatic which lends the engine a thrashy, rubbery character when pushed, but is nice and predictable at lower speeds.

The rev-happy engine is also quite noisy when a lot is asked of it, and like a lot of Japanese cars, but Subarus in particular, tyre roar picks up in the cabin above 80km/h.

It’s a comfortable and family-friendly drive, and I particularly like the way the plethora of active safety systems sit by the wayside and don’t interfere with the overall experience.

It is just a bit of a shame it doesn’t move the drive experience forward by a huge amount. The current Impreza doesn’t feel meaningfully different from the fifth-generation version which debuted in 2016.

The majority of active safety equipment is standard across all three Impreza variants including auto emergency braking up to freeway speeds with reverse auto braking, lane support systems, blind-spot monitoring with rear cross-traffic alert, traffic sign recognition, lead vehicle start alert, driver attention alert, and adaptive cruise control.

Stepping up to the 2.0R or 2.0S nets you the front parking camera for a 360-degree parking suite, and high-beam assist for the LED headlights.

Expect the usual traction, brake, and stability controls, alongside the more modern torque vectoring system and an impressive suite of nine airbags. The new Impreza is yet to be rated by ANCAP.

Mazda offers a five-year/unlimited kilometre warranty, with five-years roadside assistance… and that’s nothing special nowadays.

Service intervals are at 12 months or every 15,000km.

A fixed-price service scheme is available, averaging out to $434 annually over the first five years. Mazda shows pricing right up to 16 years and 240,000km on its website.

Subaru offers its fairly standard five-year and unlimited kilometre warranty on the Impreza, with 12 months of roadside assist included.

There is also a five-year fixed-price service program covering the first 75,000km, although it’s nowhere near as affordable as the Corolla or i30, coming in at an average annual cost of $464.64.

The Impreza needs to be serviced once every 12 months or 15,000km, whichever occurs first.
