2021 Mazda 3 vs 2020

What's the difference?

Granted. The Mazda3 X20 Astina is an expensive mainstream-branded hatchback from Japan. This is not your aunt’s BJ 323 Protégé Shades.

Still, as with all the current-series BP 3s, the fundamentals are spot on – evocative design inside and out, obsessive detailing, superb quality, progressive engineering and delightful dynamics – in a safe, practical, reliable and brilliantly efficient package to boot.

We understand that, for some people, the X20 Astina strong but silent-type personality may be too understated. But the fact remains that it is a graceful yet forceful and fast grand touring hatchback when called upon, with all the athleticism and sophistication that implies.

Mazda’s hype around the Skyactiv-X powertrain promised Wonder Woman but the Diana Prince we have instead still makes it a marvel. Maybe you should hold on a little longer and wait for the more powerful model expected imminently. Either way, you’re in for something special. The 3’s controversy rages on.

The SkyActiv-X pushes the Mazda3 to new heights of refinement and reinforces the fact it’s still one of the best cars behind the wheel amongst its peers.

Mazda has made it subtle to a fault, so people will just have to believe you when you tell them this expensive little car pushes the bounds of how a non-turbo 2.0-litre engine can feel.

It’s great to see this new tech really does what it says it will do though, so we’re keen to see where Mazda can take it from here.

Here’s where the Mazda3 really starts making up ground.

Love it or hate it, the BP-series’ design is a statement of huge ambition, melding a svelte coupe-like silhouette with a broad stance, sinewy surfacing and startlingly pared-back detailing.

This is the brand’s boldest-looking small car since the 1993-1998 BA Astina (Lantis/323F/Allegro/Artis elsewhere) – a five-door coupe styled by an ex-Porsche designer involved with the 924, 944 and 928. Disclosure time: your author bought a ’96 1.8 manual recently and is in love with its styling.

Anyway… with hints of those as well as the epochal Alfa Romeo Alfasud, the latest Mazda3 looks like a million dollars – handy for a company wanting to move up in society – and so deserves to go down in history as one of Mazda’s bravest moves.

From a functionality point of view however…

There’s nothing interesting about the SkyActiv X’s design at all. In fact, from the outside, the only way you’d be able to tell this car apart from a regular Astina is the SkyActiv X badge on the back. There are no funky eco-look wheels, coloured pinstripes, or sticker-work as some other brands choose to go with.

I hope you weren’t trying to impress your neighbors with your damn-fangled engine tech then, because they’ll be none the wiser. Then again, they probably wouldn’t be able to tell a Hybrid Corolla apart from a regular one, so maybe subtlety is key here.

Inside is the same deal. There are no badges, alternate trims, or coloured highlights to let you know you’re in something a bit different.

The most significant change on the inside is buried two menus deep in the multimedia system. It’s a new energy monitoring screen to add to the fuel monitoring suite which shows you how power is being used in the car, and importantly, whether or not the engine is using the special combustion technology. There are some conditions on it which we’ll explain later.

So, it’s not special to look at, but does it need to be? Most people would say no. We all know the Mazda3 is a great looking car (arguably one of the best in this segment) whether you choose the sedan or hatch, so at least you won’t have to make a drastic style choice either way.

Here’s the deal. Mazda3 sales have been steadily declining globally, as with most small cars – because people no longer want low-riding hatchbacks when high-riding crossovers like the Nissan Qashqai cost barely anymore yet allow their drivers to lord it over others.

So, it makes sense that Mazda decided to make the newly-created CX-30 as the practical, jacked-up version of the 3, while the hatch became the sleek and interesting coupe-like alternative that said something about its driver. Mazda hasn’t said actually said as such, but it’s patently clear that this is a painstaking, design-led exercise.

Coupe-like. That means a comparatively low roofline, making entry/egress a stoop-forward affair. Actually, though, the 3’s not too bad, and is still quite painless to move in/out of. 

But not as painless as the smooth, soothing and stylish shapes of the dashboard. Flowing, integrated and minimalist in appearance, it’s as strong a design statement as the exterior. It’s also proudly Japanese in flavour, texture and intricate quality. As we’ve observed in the recent past, luxury European brands cannot achieve this level of aesthetics and craftspersonship at the Mazda’s price point. Just look at a base A3, A200 or 118i and their Les Mis levels of austerity. The Astina continues to close the gap.

Just drilling into some of the 3’s interior details, the driving position is first class.

Thoughtful ergonomics, plenty of adjustability from the steering column and seat, arguably the greatest steering wheel in the business today due to its large, thin rim and classical three-spoke visage that’s just a delight to behold, and perhaps the most beautiful analogue-like digital instrument dials at any price point. Crisp, clear and pared back, you might imagine if Saab was still around this is what you might find in.

As we’ve mentioned in other reviews, the dials and surrounding air vents are reminiscent of the latter 944/968-era Porsche equivalents in their presentation. Gorgeous. So are the head-up’s colour data display, nifty little paddle shifters, stubby little auto gear lever (with the ‘+’ a pull-back action and the ‘–’ downshift a light push forward) and oiled tilt/telescopic column adjustment.

We’re talking about a range that starts from $26K here, folks!

Our $41K Astina’s red faux-stitched vinyl dash covering further provides a classy contrast to the smooth plastics and metal finishes peppering the cabin.

Keeping in mind this is a traditionally proportioned two-box C-segment hatchback, there’s sufficient space for four people, and a fifth at a squeeze. The front seats are well padded in the cushion, supportive in the backrest and fine even after hours behind the wheel. We must mention, too, that having a passenger seat-height adjuster is great. There’s ample space to stretch too. Storage is excellent, as is ventilation and the way everything is put together, and the overall sense and ambience is of premiumnness.

Much the same applies in the back, with a split/fold rear backrest that offers a comfy angle, while the cushion is also well padded. Knee room is fair, but headroom isn’t great if you’re tall, as the falling ceiling line reveals. Most amenities you’d expect are present back there, such as face-level air vents, access to USB charge points (located in the big bin between the front passengers), a folding centre armrest, cupholders and useful door pockets.

However, a few design-related flaws may irritate some people. Like the ultra-thick door pillar that limits the size of the back-door windows, creating elephantine blind spots for some passengers. It’s a bit gloomy back there as a result, and that’s not helped by some of the lower-lying plastic trim that are fine in a $30K hatch but seem a little cheap compared to an A3’s.

And then there’s the multimedia technology, which hasn’t been keeping pace with the latest offerings from other brands. Where is the wireless phone charger, WIFI hotspot and rear-seat USB ports? Passengers must lean forward and fumble with one of the two outlets sited up front, with ungainly cords getting in everybody’s way. And the sunken 8.8-inch widescreen is not big enough nowadays and already looks and feels dated in its operation.

Finally, there is the meagre cargo capacity. At just 295 litres, it might embarrass the Corolla hatchback’s 217L item, but it is roundly beaten by almost every other competitor. The aperture to put stuff in is large enough, with a long and wide flat floor that of course is extended when the 60/40 backrests are dropped, but the rake of the hatch and height of the load area eat away at those precious litres. The spare is a space-saver item underneath.

Overall, then, the interior is an aesthetic success and the limitations are there for everybody to see the moment they first climb inside – poor rear-seat vision, multimedia-related shortcomings, low roof line when exiting the back and that smallish boot.

Yet the Astina’s richness inside is obvious. Nobody will sit here and think they’re in a mid-ranking Corolla competitor. Not until they see the Mazda badge anyway. 

Again, no major changes to report here. The Mazda3 remains the same as before inside and out when it comes to dimensions. This means healthy space for front occupants, complete with lovely soft leather-clad trims on the doorcards and centre console for your elbows.

There are two smallish cupholders somewhat clumsily placed in front of the shift lever, a small binnacle in front of that, a large centre console box, and useful bins in the doors.

The pared back design makes for ergonomic button controls. Mazda’s dial-controlled media system takes a bit of getting used to, especially when using CarPlay or Android Auto, but some prefer it. Rear visibility is less compromised in the sedan as tested compared to the closed-in space which features on the hatch.

Back seat occupants get average legroom for the class, although they will benefit from the same relatively lavish soft leather-trimmed surfaces.

Boot space continues to be an issue for the hatchback with 295L, while opting for the sedan as tested here will well and truly solve the issue as it offers 444L.

The future isn’t cheap, and the new Mazda3 wasn’t a cheap car to begin with.

The new SkyActiv-X engine will be sold in just one trim level, the top-spec Astina, and will carry a $3000 premium over an identical car with the old naturally aspirated 2.5-litre ‘G25’ powertrain.

It makes for an MSRP of $41,590 in automatic form, as tested here. Mazda’s new premium push has compounded with the extra cost of the new engine to put the price dangerously close to premium car levels. A new BMW 1 Series, for example, can be had for $45,990.

It has to be said at this Astina grade, Mazda packs in the equipment. Standard fitment includes 18-inch 'gunmetal' alloy wheels, an 8.8-inch multimedia display (not a touchscreen) with Apple CarPlay and Android Auto support, built-in nav, digital radio, and Bluetooth connectivity, a slick Bose audio system, leather interior trim, full LED front lighting, heated auto-folding wing mirrors, push-start ignition, keyless entry, a sunroof, and a 360-degree top-down reversing camera.

There are some above and beyond additions, too, like a holographic head-up display, semi-digital dash, and a truly thorough safety suite. Alarmingly though, despite the electrical system overhaul, this Mazda is still missing advanced connectivity like USB-C and wireless charging. Seems like a petty complaint, but still one I’m going to make in the context of an over $40K hatchback.

The SkyActiv-X grade has a mild-hybrid system backed by a lithium ion battery which helps to power on-board auxiliary systems and "assist the engine." Unlike hybrid tech from Hyundai or Toyota, however, this system does not directly drive the wheels.

This is the clincher, really. The problem this car will face is being unable to take buyers away from hybrid Toyotas which are far more competitively priced, boasting even better fuel consumption.

The X20 Astina is powered by a 1998cc 2.0-litre supercharged twin-cam four-cylinder petrol engine, delivering 132kW of power at 6000rpm and 224Nm of torque at 3000rpm.

It drives the front wheels via a six-speed torque-converter automatic transmission, with an 8.6 second time to 100km/h, on the way to a 216km/h top speed (in European-spec models). There is also a six-speed manual available, though not the all-wheel drive offered elsewhere.

The combustion process is what’s different to the regular 2.0-litre engine on which the Skyactiv-X is based upon.

Dubbed Spark Controlled Compression Ignition (SPCCI), it means the engine switches between normal spark ignition to diesel-like compression ignition combustion, by using a spark to trigger both types of combustion at different times during the fuel injection process – lean during the intake stroke and atomised fuel around the spark plug during the compression stroke. The Rootes-style supercharger, meanwhile, is there to boost low-speed response, not to reel in Honda Civic Type Rs.

There’s also the integrated starter generator and 24V lithium-ion battery – the latter stores regenerative brake energy to power the former – to help save fuel.

Here’s where it gets interesting. The SkyActiv-X X20 drivetrain is a 2.0-litre four-cylinder non-turbo petrol engine.

The trick? It blends the principles of spark plug ignition with that of diesel combustion ignition. Now to be clear, sparkless ignition would be the holy grail here, and that’s not quite what this engine does.

Mazda calls the tech spark-controlled compression ignition. It works by blending a lean mix of predominantly oxygen on the intake stroke in with a second injection of much richer fuel when the cylinder reaches close to its maximum compression. The spark plug then fires, and Mazda says this fuel mixture will then more fully combust thanks to the extra compression present.

According to Mazda at least, this means less wastage, more power, and cleaner emissions which are free of unburnt or partially burnt fuel.

Previous information had this engine feature a supercharger, and the brand's representatives confirm that some form of supercharging is present, however it is mainly "used as an air pump" for "ensuring an adequate supply of air is created" so that this new combustion cycle can take place.

Power has been boosted to 132kW/224Nm from the normal 2.0-litre’s 114kW/200Nm. Importantly, the peak torque figure arrives 1000rpm lower at just 2000rpm, getting close to the responsiveness of a turbo unit.

The SkyActiv-X is front-wheel drive only via an updated version of the brand’s six-speed torque converter automatic which is promised to be even more refined than its predecessor.

The new engine is also paired with a 24-volt mild-hybrid system which does not drive the wheels directly but assists the engine and auxiliary systems in the car.

OK, so far, so good. But does the X20 Astina deliver diesel-like fuel economy?

The answer is… sort of. We drove ours in searing summer heat, air-con on, and always more than one person driving, mostly around the city and suburbs, but also out on the open road, and with some very spirited performance testing.

Mazda’s tests show the X20 averaging an official figure of 5.5 litres per 100km, for a carbon dioxide emissions average of 135g/km, while we managed a pretty good 7.9L/100km at the pump. Past tests with diesels produced similar numbers, when the regular petrol equivalents were in the high 8s and up. We’d consider this a qualified success given the demanding conditions it was subjected to, but not the panacea some of the company’s hype would have us believe.

Note, too that the X20 must drink 95RON premium unleaded, though the cheapest petrol around at the moment – 94 RON E10 ethanol – is fine too.

Fitted with a 51-litre tank, over 925km between refills is possible.

All this new technology claims to cut 1.1-litres per 100km from the combined cycle fuel figure of an equivalent 2.5-litre Mazda3, down to a total of 5.5L/100km for the automatic (as tested).

Real world figures tell an interesting story. While my recent test of the 2.5-litre car produced a blow-out of 8.4L/100km, three days of driving the SkyActiv-X around in mixed conditions had it produce a much lower figure of 6.4L/100km.

So not only was the new engine more responsive, it was much closer to its claimed number on fuel, too. Emissions (often the real reason for advances in engine tech these days… ) have also dropped markedly from 152g/km of CO2 to 135g/km.

Interestingly, the SkyActiv-X engine requires 95 RON mid-grade unleaded petrol in Australia, contrary to previous information which suggested not only would the technology run on base 91, but it would actually run better.

Mazda says the 95 requirement is due to the high sulfur content of our entry-level fuel (a comment frustratingly echoed by other manufacturers), and it’s more a durability issue than one of octane. The brand’s representatives assured us 95 RON does not significantly affect the combustion ignition process.

As with all Mazda3s the SkyActiv-X has a 51 litre fuel tank.

Any doubts surrounding the latest Mazda3’s ability to compete with upmarket European alternatives should by now be fading, given the Astina’s design, engineering and safety.

For the most part, the good news keeps on coming on the road as well – but a level of expectation management is required if you’re expecting a supercharged hot-hatch performer, because this simply is not that sort of car.

Mazda makes a lot of noise about how much quieter and more refined its vehicles are even compared to the last generation released in the mid-2010s. This is no more obvious than in the Mazda3, with an interior that is as quiet and as isolating as the best of them. We’re talking Golf and Lexus, if you need reminding.

However, this may cause some disappointments in other areas, because the X20 Astina is almost shy about the way it delivers its substantial performance.

The powertrain is surprisingly smooth and hushed for a Mazda engine that thrives on revolutions to perform, with an effortless flow to the way the car sets off and accelerates. In fact, the X20 launches off the mark with quite a bit of urge – and without lag or hesitation from the eager transmission – building up speed quickly.

What is missing is the turbo wallop of, say, a Golf TSI or Focus EcoBoost engine. Instead, there’s a very definite groundswell of performance. Like its non-X siblings, the 3’s 2.0-litre atmo engine relies on revs for power, but in the X20, usefully more torque seems to come on stream at the same time, so once on the move, throttle response is really willing and able. Certainly, stronger than that 0-100km/h time of 8.6s suggests. And you don’t need to visit the red line and endure the regular 2.0-litre’s metallic howl as a result. Get used to squeezing the accelerator in the mid ranges, and you’ll realise just how fast this can be.

Mazda has already released an uprated X20 specification in Japan, raising the power and torque outputs to 140kW and 240Nm. If punchier and more dramatic performance is the upshot, then we’d welcome that. The Skyactiv-X’s charms blossom with familiarity.

If the Astina’s power delivery is nuanced, its handling is delicate, with steering that’s light yet measured and involving, providing accurate and flowing roadholding that remains consistent and controllable even as speeds rise. Bumps don’t faze the suspension, which just sticks gamely to the road. The Mazda walks a fine line between being luxurious and feeling sporty, with an unruffled agility that’s very satisfying for keen drivers to explore.

Earlier, we said the cabin is remarkably quiet – and not just by Mazda standards. That MacPherson-style front/torsion beam rear end might seem simple on paper, but it manages to provide a civilised and sophisticated ride. Some of the bigger bumps reveal a slight firmness to the chassis tune, but the car isn’t crashy or loud around town, simply gliding along with confidence and ease.

Where the Mazda3 loses some of its edge is in its poor rear vision, which can make parking it in tight spots a little harder than it needs to be. There aren’t the clear views out of most urban SUVs, making the latter’s ascension in the sales charts understandable.  

That’s the price of that coupe-like silhouette.

I wasn’t sure what to expect. How does a different injection method feel?

After three days behind the wheel I can confidently say most people won’t really be able to tell the difference, but that’s not to say there isn’t one.

Quite the opposite in fact. This new engine’s bump in power and more readily available peak torque are notable.

I spent most of my drive time with the energy monitor screen set, so I could try to understand how this new engine reacted to my inputs. The combustion ignition (SPCCI) mode is working most of the time. It doesn’t run at idle, and Mazda says it won’t run at ‘high loads’, but it seems to always be on past about 1200rpm in normal driving.

Once it reaches that point, the revs surge up quickly, almost like a turbocharged engine. It’s not quite as full-on with its surge of power, but it is very noticeable.

It gives this car a kind of comfortable pulling power kick which is at least on-par, but probably better, than the equivalent 2.5-litre engine (without being able to test them side-by-side), despite its higher power figures.

I wish I could tell you there was some big ‘wow factor’ moment here. Like it sounds really great once it’s on song, or it has a snapping-on feeling like Honda’s once-lauded VTEC. But it doesn’t. This engine has a unique tone, sure, but it’s quiet and subtle, and the delivery of power is quite linear.

In fact, the whole drive is notably smooth and refined. A cut above the rest of the Mazda3 range. The engine sounds distant, even when pushed, and the transmission has been smoothed out further between gears and re-calibrated to better deal with the new powerplant’s readily available bump in power.

As always, Mazda’s 'i-Stop' stop/start technology is one of the best on the market, to the point where you won’t even notice it’s there. The efficiency of this system has apparently been given a boost by the new 24V hybrid system, but again, there’s little tangible difference in terms of how it feels.

The energy monitor really made me wish this car was just a traditional hybrid. I don’t doubt whatever comes next will be. it would be a truly fantastic step forward to blend the benefits of this engine with a true hybrid drive for even lower consumption.

The drive experience imparts a sense the SkyActiv-X simply does what it claims to do. It’s a shame there’s nothing particularly exciting for driving enthusiasts (apart from how cool the tech is), but it really lives Mazda’s current ethos of constantly tweaking and improving what it has to work with, without any radical changes to what consumers expect behind the wheel.

The same excellent suite of active safety items available on other Mazda3 Astina variants is offered here, meaning freeway-speed auto emergency braking (AEB), reverse AEB, lane keep assist with lane departure warning, blind spot monitoring, rear AND front cross traffic alert (uses sensors to see around objects which might block your view when pulling out), traffic sign recognition, as well as adaptive cruise control with stop and go function.

On the expected side of things there are seven airbags, the expected brake, stability, and traction controls, as well as dual ISOFIX and three top-tether child seat mounting points across the rear seat.

Unsurprisingly, the Mazda3 carries a maximum five-star ANCAP safety rating as of 2019.

Mazda offers a five-year/unlimited kilometre warranty as well as roadside assistance on all Mazda3s, as well as capped-price servicing, scheduled at every 12-month or 10,000km intervals.

Published online, the prices for the X20 vary between $344 and $374 annually, and are listed for up to 16 years/160,000km. Note, however, that additional scheduled maintenance items that must be replaced or attended to will increase that price as the vehicle ages.

All Mazda3s, including this new variant, carry a five-year, unlimited kilometre warranty promise competitive with competitor marques, including five years of roadside assist.

Service pricing was not available at the time of launch, although Mazda told us it shouldn’t stray far from the current 2.5-litre engine option which costs between $315 and $359 on alternating years for the life of the warranty.

Service intervals should also remain the same at 10,000km or 12 months whichever occurs first.
