2018 Mazda 3 vs Mazda CX-3

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.

With the obvious exception of Two and a Half Men, things are usually popular for reason, and that is they're good. And the CX-3 deserves to be duking it out for the top sales spots in the segment.
 
It's a city car, of course, and so it shines brightest in the urban jungle, but its stylish design and top-class safety offering are pretty sizeable selling points for Australias's city dwellers. 

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 good news is, it still looks very good. But mostly because it hasn't really changed.

And that's no bad thing. In fact, we think it might be the best-looking option in its segment - something that has hurt its sales not at all - owing mostly to its swooping, perfectly-proportioned exterior that makes the CX-3 look both fashionable and fast.

Mazda’s littlest SUV is unashamedly built for the city, but the use of black body cladding lends a vague sense of ruggedness to its design, while the power-domed bonnet hints at sportiness - even if it never quite materialises from behind the wheel. 

Climb inside, and the CX-3’s interior is simple and unfussy, with a padded panel that runs the length of the dash breaking up the harder plastics. It's a clean and premium-feeling design, and only the materials in places would prevent it from looking at home on a far more expensive model.

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.

You can basically split the city-size SUV field into two categories: small and smaller. And the CX-3 falls into the latter category. The 4275mm long, 1765mm wide and 1550mm tall CX-3 is based on the Mazda2 city car, so while it might be the most stylish in its segment, it’s not the most practical. 

Life is good for front seat riders, though, where the cabin doesn’t feel tight at all. There are two cupholders on offer, along with two USB points and a 12V power source, and each of the front doors has room for bottles.

Things do get tighter in the backseat, where even a single (bulky) car seat can swallow up most of the available space - something I know from personal experience. Best stick to two grown-up passengers back there, too, as shoulder room feels much tighter than legroom.

Backseat riders are at the mercy of the driver and front passenger when it comes to entertainment or climate, with no USB outlets or air vents. But there are two ISOFIX attachment points, one in each window seat in the back. 

Boot space is a roadtrip-limiting 264 litres with the 60/40 split rear seats in place, but that number grows to a usable 1174 litres when they're folded flat.

CX-3 pricing kicks off with the Maxx from $22,890, but that money will buy you a manual transmission (which nobody wants). Instead, our automatic-equipped test car lists at $24,890 in front-wheel drive (FWD), and $26,890 for the all-wheel drive (AWD) version.

That money will secure you 16-inch alloy wheels, keyless entry (and push-button start) outside, while inside you'll find cloth seats, manual air-con, cruise control and sat nav, along with a leather-wrapped gear shift, handbrake and steering wheel - the latter with wheel-mounted controls.

Tech is covered by a 7.0-inch colour screen that pairs with a six-speaker stereo, and also arrives with internet radio apps - but no Apple CarPlay or Android Auto.

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.

The CX-3’s naturally aspirated 2.0-litre petrol engine produces 109kW at 6000rpm and 192Nm at 2800rpm - plenty in a car that weighs 1282kg - sending that power to the front wheels (though an AWD option is available) via a six-speed automatic transmission.

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.

Offical claimed fuel use is pegged at a frugal 6.1 litres per hundred kilometres on the combined cycle, with emissions a claimed 146g/km of C02. The CX-3’s 48-litre fuel tank will accept cheaper 91RON fuel, too.

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 great white shark has evolved over millions of years to become the perfect apex predator, perched at the very top of its food chain. Just so long as you keep it in the ocean. Drop one in the Serengeti, for example, and things aren't looking quite so rosy for old Jaws.

And it’s the same with Mazda’s little CX-3, only in fast-forward. The city SUV segment has only had the a handful years to complete the evolution process, but its been every bit as effective. Keep the CX-3 in its natural, urban habitat and it feels positively meant to be. 

The engine feels perky and smooth if you use gentle inputs, the steering is light and direct, and its diminutive dimensions make it an absolute doddle to park just about anywhere.

Vision from up front is great, and it’s a mostly quiet and smooth drive across the city’s blacktop.

Vision from up front is great, and it’s a mostly quiet and smooth drive across the city’s blacktop. It shines on twisting roads, too, where the firm-ish suspension inspires confidence, and the smooth surge of the naturally aspirated engine shifts the little CX-3 in and out of corners with ease.

But venture outside the city walls and it feels out of its depth. This is not designed as a long-distance cruiser. For one, the engine can get a little loud and unrefined when you really plant your foot, and with the rear seats in place, the boot is really only big enough for a pair of soft bags - big, hard suitcases need not apply. Road noise, too, creeps in at freeway speeds. Like a shark in the Serengeti, then.

But it should surprise nobody that CX-3 shines brightest in town. And if you’re city-dweller, the CX-3 is a popular choice for a reason.

It's hard to fault the safety package on the CX-3 Maxx, which is overflowing for a car at the price point.

Expect six airbags (dual front, front-sides and curtain), which are joined by rear parking sensors, a reversing camera and a clever AEB system that works in forward and reverse. 

Blind-spot monitoring and rear cross-traffic alert round out the standard safety list, helping earn the CX-3 the maximum five-star ANCAP safety rating when crash tested in 2015.

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.

Mazda has not followed the long-warranty lead of Hyundai, Kia and others, instead offering a three-year/unlimited km warranty. The CX-3 will require a trip to the service centre every 12 months or 10,000km - a trip that should be made less painful thanks to capped-price servicing, with service pricing listed on Mazda's website.
