2018 Mazda 3 vs Honda Civic

What's the difference?

The 3 is a terrific car and continues to improve with every yearly update, however minor. The uplift in the Neo Sport may not look like $1000 worth, but having that proper screen and reversing camera - along with standard AEB - starts to make sense over time.

In 2017, I said the pick of the range was the Maxx and I still reckon the Maxx Sport is the one to go for - it has a good package of safety equipment and a sensible spec list, without the frippery of the increasingly oddly priced Touring. The not-that-much-more SP25 is similarly specified, but only worth it if you want the extra power. Not everyone does.

The new i30 and forthcoming new Corolla are giving the Mazda3 more of a hurry-up these days, especially in price and spec but the i30 now has the driving dynamics to go with it. And with the Kia Cerato rapidly closing in, every little bit of competition is making the 3 a better car than before.

And it's still by far the best-looking car in the segment. For many, that's what will tip them over the edge.

A comfortable and convenient daily driver that ticks all the safety and tech boxes, the VTi-LX is a compelling offering given it is better value than the RS, and not overpriced for its spec level. 

What it lacks in an interesting powertrain it more than makes up for with its huge cabin space and well sorted ride. Whether you choose it or not could very well come down to the looks…

The 3's exterior design is still a winner to my eyes. Based on Mazda's Kodo design language, it looks great in just about any colour and the company's commitment to beautiful paint some years ago is still paying dividends.

It's a lovely, flowing design that looks best in the sedan and few cars in the segment are as genuinely pretty. About the closest you'll get for commitment to design is the Alfa Giulietta.

As you climb the range, the detailing in items like the lights and brightwork mark out the spec level, with additions like chrome exhaust tips and LED daytime running lights.

The range is available in seven colours - 'Sonic Silver', 'Jet Black', 'Deep Crystal Blue', 'Titanium Flash' (a sort of bronzey brown), 'Snowflake White' and 'Eternal Blue'. Mazda continues to be absurdly generous and offer those colours as no-cost options. 'Machine Grey' and 'Soul Red Crystal' (this one is a ripper) are a still-reasonable $300.

Unlike previous versions, there's no yellow or purple paint available.

Inside is well-executed but is a bit grey and drab, especially in the lower-spec versions. I recently drove a Touring with contrasting colour panels in the doors, but it was a deep rich red that barely stood out from the grey. 

Some touches, such as satin silver dash parts, do lift the colour a little but it's fairly nondescript. Mazda also persists with the frustrating single-dial-with-wings dashboard that I really don't like very much. Still, few others complain, so it's probably just me.

The look of the 10th-generation Civic is best described as polarising. There's a slew of hard angular edges pointing in all directions, which makes an overall design theme hard to pinpoint. The elegant curvature of the Mazda3, or the more conservative lines of the Hyundai Elantra and Subaru Impreza perhaps appeal to a wider audience.

As I mentioned earlier, the almost-as-well-equipped RS spec comes with some touches that could make all the difference here. The blacked-out bars across the RS’s front, side and rear compliment those angles a lot better, and the rear looks far more resolved with a spoiler (what are those rear light clusters pointing to?).

In comparison, the LX looks incredibly plain and, aside from those LED lights, it is honestly difficult to tell it apart from the VTi-L or even the base-model VTi. While subtlety might appeal to some, it’s an odd card to play for a flagship variant given the overall design of the Civic screams ‘look at me’.

The ‘Modern Steel’ grey colour of our test car rammed the plain-Jane look home. If it were my choice I’d go for the ‘Brilliant Sporty Blue’ as it suits the car’s angular aesthetic a little better. The only free colour is ‘Rally Red’.

The 17-inch alloys were also a topic of controversy in the office. Over my drive week I came to appreciate the milled-alloy with gloss-black highlight designs. Matt Campbell disagrees. I will concede they look smaller than 17-inches, likely due to the black highlights.

Inside is a better story. The angular design trend continues, but it’s all very ergonomic. None of the materials appear cheap or nasty, and there are more than a few soft finishes in the right places. It doesn’t have the symmetry of the Elantra’s interior, but I became very used to how comfortable it was.

Of particular note is the chunky, leather-bound steering wheel, and I have to give props to the low, sporty seating position.

Housed in the dash is a digital display which well laid-out, presents all the important information to the driver well, has a high frame-rate and seemed to never be subject to glare. It’s no premium bells & whistles experience like Audi’s Virtual Cockpit but is a nice addition nonetheless.

The 3 comes in two body styles - four-door sedan and five-door hatchback. The most popular is the shorter hatch, despite the loss of luggage capacity. The different boot space dimensions deliver 308 litres in the hatch while the sedan has 408 litres. For load capacity, the sedan is the clear winner.

The hatch's boot size isn't exactly a world-beater but it does feature a cargo cover to hide your valuables.

The interior dimensions are unchanged, meaning good if not outstanding rear leg room. The cabins are basically the same, so if you refer to our interior images, you'll note only minor differences.

The cup-holder count differs depending on which specification you choose. The Neo Sport has just two, for the front passengers. In the rest of the range there are two up front and two in the rear, with bottle holders in each door as backups. Some models feature extra storage space for books or devices but there's no sunglass holder until you reach the Touring.

The turning circle is a fairly standard 10.6 metres, so most suburban streets need a three-point-turn manoeuvre. Park assist is limited to beepers and the reversing camera.

Ground clearance when unladen is 160mm, so all but the steepest driveways won't present a challenge, but going off road is not on the menu. Kerb weights range from 1258kg for a Mazda3 manual Neo to 1336kg for an auto Astina.

Gross vehicle weight ranges from 1800kg to 1875kg.

Does the Civic sedan look a little… big to you? That’s because it is. It’s massive inside. But somehow, it shares a wheelbase with the hatch.

It’s kind of magic, but that’s one of Honda’s fortes. Big practical interiors with some hidden surprises.

What surprised me the most though, is the ridiculous rear legroom. I had leagues of space behind my own driving position. How can this be if it has the same wheelbase as the hatch? 

Well, some investigation revealed that despite its near-identical looks, the sedan's cabin is physically different from the hatch, and an additional 34 millimetres of legroom is granted in the back. It doesn’t sound like much but makes a world of difference.

It legitimately has far more legroom than even some ‘large' sedans I’ve driven and ridden in, and the centre seat could fit an adult-sized human in decent comfort for a long-distance drive. Impressive.

The boot is also close to largest in the class. With the seats up, there’s 517 litres (VDA) of space on offer, which compares very well with the Mazda3 (408L), Elantra (458L) and Impreza (460L) but is just barely eclipsed by the new Kia Cerato (520L).

In the cockpit too, there’s plenty of stowage space under the centre console including two large movable cupholders (although without those little variable edges, so a tilt-risk for small stuff) plus some smallish cubbies in the doors for front and rear passengers. These won’t hold larger belongings or bottles, but they’re sufficient for smaller objects like wallets, books or keys.

Everything is also very easy to reach, but the sunroof eats a little headroom which could be a challenge for those over 182cm tall. I also had to question the choice of not including a dial for volume control. There are wheel-mounted buttons and a touch interface on the screen itself. But that’s kind of clunky when you need volume down in a hurry.

Okay, so you’re looking at a sedan, so there’s a good likelihood you’re looking for a value offering. Because, if you were following the current impulse buying trends you'd be researching an SUV and, if you really cared about practicality, you'd be after a wagon.

Well, there’s no Civic wagon, but our VTi-LX sedan here is the top-spec car. Coming in at a before-on-road cost of $33,590 it competes with other small sedan flagships, the Mazda 3 SP25 Astina ($33,490), Hyundai Elantra SR Turbo ($31,290), Subaru Impreza 2.0i-S ($33,250) and the new Kia Cerato Sport+ ($28,290).

Accounting for most value factors, the VTi-LX stands up reasonably well. Featured is a full array of LED lighting (DRL, headlights and foglights), sunroof, dimming rear mirror (nice addition), leather appointed interior trim with heated seats and six-way power adjustable driver’s seat, 452-watt audio system with DAB+ and, built-in sat nav.

There’s also Apple CarPlay and Android Auto available through the 7.0-inch touchscreen, and unlike competitors, the odd addition of an HDMI port (you can hook everything from laptops to gaming consoles up to the main screen).

The native user experience on the touchscreen is far from best in the segment, however. It’s clunky and slow, and I had trouble finding some of the features. The implementation of Apple CarPlay was even kind of dodgy at times, with it crashing out occasionally.

I’ve never had trouble with competitor systems in Hyundai and Kia products and, while you’ll do without Apple CarPlay or Android Auto in the Mazda3, it’s still a much slicker system than the one in the VTi-LX.

One major value factor to consider is the ‘HondaSensing’ safety suite which makes the VTi-LX the only Civic to include all the key active safety items. This is a major value consideration, so keep an eye out for more details in the Safety section of this review.

From the VTi-L up you also get the convenience of push-button start and keyless entry. 

Sitting just below our VTi-LX is the RS spec level which I recently tested in hatch form. In sedan guise the RS costs $1800 less and is almost identically equipped apart from the safety suite which is worth every penny. Unless the relatively understated look of the LX is a deal breaker, my advice is to spend the extra cash.

There are two engine specs in the 3 range. Both are equipped with Mazda's 'i-Stop' stop-start technology but goes without the 6's 'i-Eloop' regenerative braking battery charging tech. Every model comes with a choice of gearbox, either a six-speed manual or six-speed automatic. The automatic is a traditional auto rather than the dual-clutch you might find in a Golf.

Both engines run on standard unleaded, use a standard oil type. Oil capacity is model dependent, and can be found in the owners manual. An oft-asked question is whether the 'SkyActiv' engine uses a timing belt or chain - we can report the engines are both chain-driven.

The Neo Sport, Maxx Sport and Touring all come with the 2.0-litre SkyActiv with 114kW and 200Nm of torque.

The SP25, SP25 GT and SP25 Astina are, as the name suggests, equipped with the larger 2.5-litre motor which churns out 138kW (almost exactly 200 brake horsepower in the old money) and 250Nm.

Towing capacity is rated at 1200kg braked and 600kg unbraked regardless of engine size.

The diesel vs petrol argument has long since been settled with the demise of the punchy but not particularly popular XD. So you won't have to worry about a diesel particulate filter replacement any more. There is no LPG or turbo sport edition, like the unruly old MPS3 performance car.

Performance figures vary between the two engines - the SP25 auto should complete the 0-100km/h acceleration test in just under eight seconds, with the 2.0-litre cracking it in around nine seconds. The manuals will likely be a tenth or so slower.

Up this end of the Civic hierarchy, there’s just the one drivetrain. A 1.5-litre turbocharged petrol engine, producing 127kW/220Nm, mated only to a CVT auto. The Civic is front-drive only and, much to the dismay of old-school Civic fans, there's no manual option in sight.

That engine puts it middle of the pack compared to small sedan competitors. The enthusiast’s choice may be either the Mazda3 SP25 with a naturally aspirated 2.5-litre (138kW/250Nm) or the Hyundai Elantra SR Turbo which has an impressive 1.6-litre turbo (150kW/265Nm). Both of those can be had with a six-speed auto or DCT respectively (or, better yet, a six-speed manual option on either).

But the Civic still outshines the Cerato’s ordinary-all-round 112kW/192Nm 2.0-litre offering (which is also a bit thirsty) and Subaru’s infamously underpowered 115kW/196Nm non-turbo 2.0-litre engine which is also asked to pull a much heavier AWD layout.

Fuel-consumption figures vary slightly between the models. While the 3 has never been a fuel-economy star, as years have gone by its mileage has improved.

Official figures suggest that the 2.0-litre burns petrol at 5.8L/100km for the auto and 5.9L/100km for the manual, while the 2.5-litre consumes 6.1L/100km for the auto and 6.5L/100km for the manual.

Our own statistics suggest these ratings are a little on the optimistic side, which is no great surprise. We regularly get about 8.0L/100km in the 2.0-litre (a neat 12.5km/l) and around 11L/100km for the 2.5 (around 9km/l).

Fuel-tank capacity is 51 litres, regardless of engine size, and there's no need for premium fuel.

As I've already said, Mazda doesn't offer an oil-burner anymore as diesel fuel economy just isn't the drawcard it used to be.

Honda’s smaller engine choice and CVT is designed to be frugal. On the combined cycle, Honda claims the VTi-LX will drink 6.0-litres to 100km. There’s not too much variation in the field with Mazda also claiming 6.0 for the SP25 Astina, and at the other end of the scale, there’s Kia’s Cerato which is touted to drink 7.4L/100km.

After a week of driving over a tank of petrol I scored 7.7L/100km which is closer to (but surprisingly less than) Honda’s urban estimate of 8.0L/100km.

Despite being turbo'd the VTi-LX will happily drink bargain-basement 91 unleaded, and the tank holds 47 litres.

These days the 3 jostles at the head of the pack for driving dynamics. The MY17 model scored Mazda's new 'G-Vectoring' technology, which subtly sharpened the steering. This, along with tweaks to the front and rear suspension, has delivered a driving experience that is hard to fault. While it would be nice to have a bit more performance (the SP25 is still no fireball), it's fun to drive if you have a bendy road ahead of you.

Most of the time, though, you're in the urban grind and it is here that the 3 excels. The steering is light, accurate and  cleverly geared. The auto is a good one and even in town the light clutch of the manual makes progress easy and unfussed. Forget about the Eco mode, though - it's doughy and slow.

Over the years, Mazdas in general, but in particular the 3, have suffered from poor insulation, resulting in road noise invading the passenger space. 

Past reviews of mine, and many others, will rail against the cabin noise. Things have gotten better and continue to do so. Where in the past occupants would suffer from tyre rumble and a cacophony of suspension noise, particularly from the front, that's no longer the case. 

The noisy suspension issues have been sorted in various ways across the whole Mazda fleet and the 3 is now a much quieter, if not class-leading, proposition. But it does come close.

The Civic presents a strange dichotomy between the luxury spec and its sporty frame. As mentioned earlier, you sit nice and low in the Civic, and you have this chunky, well weighted steering wheel, giving you the illusion of sportiness at the helm.

It lives up to that by feeling nicely planted in the corners. This is largely due to all Civics having a more sophisticated independent rear suspension. Thankfully, it’s not a stiff tune either. It’s well sorted over bumpy stuff, there’s not a rattle to be heard in the cabin, and you don’t have to cringe every time you spot an incoming car park speed bump or unfortunately-positioned pothole.

The engine won’t exactly have you setting lap-times, however, and it’s a tad noisy in the cabin when it comes to really getting the power down somewhere past 2500rpm. 

Then, there’s the CVT. It truly isn’t the worst CVT I’ve ever driven (I’m looking at you, 1998 Nissan Micra…) and in terms of actual driving the experience isn’t dulled much. You should know it creates a slightly unpleasant rubbery characteristic, where your inputs feel delayed because it takes time for the CVT to react to changes through the driveline. 

For example, when laying off heavy acceleration, it will keep accelerating for half a second after you’ve taken your foot off. It’s a minor issue, but a noticeable one.

It also produces an annoying high-pitched whining sound at low speed and when you come to a full stop. You won’t be bothered by this if you drive around with the (actually great) 10-speaker stereo on most of the time, but you shouldn’t have to rely on it.

In terms of your ability to alter the engine’s characteristics, there’s an ‘Eco’ button which seems to make the CVT fight you as you try to extract revs out of it, and a sport mode on the transmission which seemed to make the accelerator a little more responsive and forced the CVT to act a bit more like a traditional auto.

Paddle-shift appears on the VTi-LX and RS grades but while the ‘gear changes’ they trigger didn’t have a long delay on them, they proved unsatisfying anyway.

This is where the VTi-LX shines above the rest of the Civic range. Finally arriving at this top-spec grade is the ‘Honda Sensing’ safety suite.

This includes Auto Emergency Braking (AEB) with Forward Collision Warning (FCW), Lane Departure Warning (LDW) with Lane Keep Assist (LKAS) and Road Departure Mitigation (RDM) as well as the welcome addition of Adaptive Cruise Control.

It’s a shame you have to spec all the way to the top of the range to get AEB (available across all Mazda3 variants), but as I said earlier, it’s worth the extra $1800 over the RS.

I could argue the Forward Collision Warning system was a little too sensitive, but as it just had large flashing light on the dash and a mild beep, it was really just comforting to know it would alert me in a real emergency.

All Civic sedans feature three top tether child seat attachment points across the back seat, with ISOFIX anchors on the outer rear positions, and carry a five-star ANCAP safety rating as of April 2017.

Rural buyers (who probably aren’t looking at a luxury Civic anyway) will be dismayed to know there’s only a space saver spare under the boot floor.

Mazda offers a three-year/unlimited kilometre warranty, with roadside assist subject to an additional yearly charge. So if you're worried about a flat battery or running out of fuel, the extra $90-$100 per year is a good investment. You can also purchase an extended warranty from your dealer.

Those worried about service costs will be pleased to know Mazda offers capped-price servicing. Your dealer expects to see you every 10,000km or 12 months, whichever comes first, and the prices are listed on the Mazda website, varying slightly between between engine types (by about $30 per service).

The 3 enjoys good resale value, with a check of our price guide suggesting a 2014 Neo will fetch between 65 and 75 per cent on a private sale, suggesting you'll have few issues when you need to shift a second-hand machine.

From what I've seen of older 3s, durability seems pretty good, even when in the hands of people who aren't all that careful with their cars. The 3 seems to suffer from few reliability issues. A quick swing through the usual internet forums uncovered no obvious common faults or defects. A search for automatic transmission problems, injector or transmission failure or other common problems yielded few genuine results. If you keep up with the maintenance, things seem fairly trouble-free for the current 3.

Diesel-engine problems are clearly a thing of the past, with no diesel offered.

Where is the Mazda3 built? An excellent question - all 3s come from Mazda's Japanese factories.

Honda offers a five-year/unlimited kilometre warranty across its range. This is great but should be the minimum.

It compares well in this segment to fellow Japanese competitors, the Mazda3 and Subaru Impreza, which fall behind with outdated three year/unlimited kilometre warranties. 

Hyundai is bang-on par with a similar five year/unlimited kilometre warranty, but the bar to beat, as ever, is Kia with its seven-year/unlimited kilometre promise on the Cerato.
