Mazda CX-3 vs BMW X4

What's the difference?

‘You get what you pay for’ comes to mind with the CX-3, which is interesting given it’s neither the newest nor most feature-packed SUV in its class.

The ageing light SUV does however offer one of the best-put-together experiences in a car of this size and its engine is powerful for the class. Build quality feels well above par and there aren’t any annoying inclusions that are becoming more common in new cars.

There aren’t many downsides unless you were hoping for a big screen and the ability to play around with software functions, but at this end of the new car spectrum, a car that drives this well and remains stylish a decade on should be applauded.

Put aside its relative (but forgivable) lack of efficiency and somewhat smaller boot than rivals, and the CX-3 nails everything it needs to.

Okay, so the BMW X4 xDrive30i is neither an ass nor an elbow, to be fair, it's more of a bulky shoulder muscle, or two.

I can't say I'll ever love the X4, the idea of it is a bit too weird for me, but I can't help admiring the way it looks and the way it drives.

It's a bit like a sedan on steroids - or an SUV on a diet, depending on your perspective - but that doesn’t take away from the fact that it’s fun to drive, comfortable and retains just enough coolness, and just enough practicality, to make it worthwhile.

For one, there’s the way it looks inside and out.

The Mazda CX-3 hasn’t remained the most popular car in its segment on price, so the fact its styling continues to age gracefully in the design-focused light SUV segment (aimed at young or first-new car buyers) must have something to do with it.

While it’s been lightly updated a couple of times since 2014, the CX-3 is still in its first generation and has stood the test of time.

Looking like a jacked-up Mazda2, the CX-3 brings some traditional aesthetic to a category peppered with more divisive and daring (but admittedly admirable) designs like the Hyundai Venue, Suzuki Ignis (RIP) or the cute but prohibitively expensive Jeep Avenger.

Some elements of the CX-3, like the chrome trim around the grille or the black plastic cladding along the bottom of the body and around the wheel arches, seemed in the past like they had the potential to age poorly, but Mazda’s design language has only slowly changed since 2015, and the CX-3 still looks at-home in the brand’s line-up.

It’s not the most adventurous - even inside its layout is quite basic - but it does give off a premium vibe and the fact it plays things a little bit safe means the CX-3’s broad appeal is undeniable.

So here's the thing. Obviously I have a personal beef with the existence of vehicles like this, but my eyes cannot deny the facts - the X4 looks fantastic. It's muscular, imposing and smooth all at once. Unlike the X6, a bigger and less visually successful attempt to play the same styling tricks with an X5, it doesn't have a ridiculous rear view that looks like it shoulders and buttocks have been fused (although it's hard to miss just how small the rear window is).

Even more impressively, there's no denying it looks better than the X3 that gave birth to it, so I can easily see why someone in a BMW showroom could be drawn to it. At least until they sit inside.

If the exterior style and eye-catching Sophisto Grey metallic paint don’t make an immediate impression then your eyes will surely widen at the interior, resplendent with bold Tacora Red seats, Aluminium Rhombicle trim finisher and the kind of sleek, classy styling that BMW excels in. 

Both the adjustable ambient lighting on the doors (we were partial to lilac) and door projectors that shot out what looked like robot wings onto the ground every time we hopped out of the X4 at night walked a fine line between futuristic cool and “parked out the front of a nightclub entrance” chintz, but over time the scales tipped more to the former. 

The big differentiator between the X4 and X3, of course, is the sloped coupé roof, a design feature that may make the X4 look a little cooler, but at the expense of cabin space, but more of that in a moment.

The Mazda CX-3 isn’t the most spacious light SUV on the inside, but from either of the front seats it’s clear a lot of thought has gone into the best way to make the cabin work.

For example, precious space hasn’t been wasted by two dedicated cupholders, instead there’s a cupholder in the central storage compartment that’s relatively easy to reach into.

Like its design and some of its features, the CX-3’s layout can’t hide its age - there are still big physical controls for the climate settings, the speedometer is a physical dial and the gear selector is a very traditional style.

Mazda’s soon-to-be-gone media control wheel persists in the CX-3, which is by no means a bad thing. It falls nicely to hand, as with many of the controls in the CX-3. Its seating position isn’t too high and the positions you’re able to get the seat and steering wheel into should accommodate most humans.

Behind the front seats it’s a little more spartan. Space is at a premium, with my 178cm frame fitting in the back seat just enough that I had a fair bit of headroom, but my knees were able to brush the seat in front, set to my own driving position.

There are no ports for charging or vents in the second row, but the fold-down armrest has a clever fold-away cupholder. The window shoulder is a little high for young kids to properly see out, but there’s enough light that it doesn’t feel cramped.

The boot is similarly diminutive, a 264-litre space becoming 1174L with the second row folded down. Compare it with the Hyundai Venue and its 355-litre boot, or the Toyota Yaris Cross and its 390 litres, and the CX-3’s simple, well-constructed interior starts to lose points.

For a car that is very much a mid-sized SUV on the outside, the interior can feel a bit too snug, like you’re driving a compact car that’s tried on a suit a few sizes too big (for reference, I’m 175cm tall - above-average height drivers may find the snugness soon turns to claustrophobia). 

While comfortable - it is BMW we’re talking about, after all - there’s not an overly abundant amount of headroom available, a feeling that becomes more pronounced should you shut the big moon roof.

My two children felt slightly too close to “you’re annoying me” distance from one another, which is to say this isn’t really the kind of car you should be getting if you plan on regularly ferrying about passengers in the rear who are bigger than a child. But I really don't think many people with kids would choose the X4 over the X3.

Boot space also takes a hit when compared to the X3 (550 litres versus 525-litres in the X4 - I was surprised the difference wasn't larger - although that expands to 1430-litres with the rear seats folded down. 

The boot opening is also mouth-shaped, which makes packing in wide-load items more of an issue.

Cupholders are plentiful - two in the front, two in the rear, and bottle holders in each door - and there’s a decent-sized storage cubby in between the front two seats. 

The sloped roof, and big fat A pillars, also result in the X4 being a bit more pinched at the rear, which is not especially great for visibility, with the vehicle’s blind spots taking some getting used to.

Cost-wise, the X4 is roughly in the same ballpark as the other cars in this strange sub-segment, but when you add in optional extras - metallic paint, panorama glass sunroof and BMW Laserlight headlights among them - the base price of $95,900 plus on-road costs sneaks up to $101,800, which is is no small figure. 

It’s also a considerable $8000 more than the SUV-shaped X3, meaning you’re essentially getting the same car, but with less cabin and boot space, for more money. To be fair, this is just part of a long tradition of the style-conscious buyer being willing to pay more for less, one that the invention of the coupe pretty much invented.

That kind of money also makes exclusions like adaptive cruise control, heated seats and wireless charging a bit of a head-scratcher.

Still, there’s plenty to love, including an M Sport kit that comes standard with the X4 (a suspension/brake package and various styling embellishments), butter-soft Tacora Red Vernasca leather seats (Sport adjustable for the driver and front passenger), 20-inch M light alloy double-spoked wheels, a head-up display, adaptive LED headlights, and an automatic tailgate. 

There’s also a generous high-resolution 12.3-inch control display and digital 12.3-inch instrument display, the former operated by touch or via the rotary iDrive Touch Controller. 

Cable-free Apple CarPlay and Android Auto are also available, but BMW allows you the option to use its iDrive system instead, just in case you're some kind of mad Munich fanboy - or you hate Apple. 

The Mazda CX-3 is still powered by a 2.0-litre, naturally aspirated, four-cylinder petrol engine, as has been the case for years. Its outputs remain at 110kW/195Nm.

It drives the front wheels only, via a six-speed automatic transmission.

Now, prepare to be confused. In the past, the 3.0 in the xDrive3.0i nomenclature might have led you to believe you'd bought a BMW with a 3.0-litre straight six engine. But in this case, you have not, the 3.0 just means you have a more exciting version of the 2.0; a TwinPower turbo 2.0-litre inline four-cylinder engine, making 179kW and 353Nm that the xDrive system delivers to all four wheels. 

The claimed zero to 100km/h time of 4.9 seconds feels completely realistic as this engine has plenty of poke. Put it in the Sport setting and you'll get some serious shove. Indeed, the switch between Comfort and Sport is very noticeable and changes the character of the car entirely.

The transmission is an eight-speed conventional torque converter automatic gearbox that’s both smooth and responsive. 

Mazda claims the CX-3 sips 6.3 litres of fuel per 100km, minimum 91 RON petrol, though on test the small SUV returned an 8.1L/100km figure under a mix of urban, highway and some dynamic driving.

With its 48-litre fuel tank, that means you’re realistically likely to get about 550km to a tank, though theoretically given Mazda’s efficiency claim a 760km trip on a single tank would be possible - if you could recreate the test lab conditions.

The X4’s 65-litre tank needs to be 95-octane at a minimum, and BMW’s claimed combined fuel consumption is 7.9 litres per 100km. The temptation to use its rorty little engine is going to push you higher, though - you chose the one with the 3.0 badge on it after all - and we averaged 10.9 litres per 100km in our week together, which was mainly city driving, to be fair. 

The light SUV category is an interesting one, as it feels somewhat like a gateway to bigger SUVs for those who get a taste of the higher seating position. But in city and urban areas, a light SUV should be as much car as someone needs - unless they have two kids or a bunch of equipment to get around with.

This comes down to the fact cars like the CX-3 are more efficient and easier to manoeuvre than their larger counterparts. And as light SUVs go, the CX-3 feels solid, confidence inspiring and more capable when outside its inner-city comfort zone.

Its naturally aspirated engine is big for the class. Even if it doesn’t feel the punchiest off the line it offers plenty of flexibility at higher speeds and makes overtaking on the highway feel less daunting than it would otherwise be in a car this small.

Its steering is light, which is an advantage in everyday driving, but has enough feedback that more dynamic driving is still engaging. It’s not sportscar-sharp, but you wouldn’t want it to be.

While its age would suggest the CX-3 should feel unrefined compared to newer small cars and light SUVs because of what lies underneath, Mazda’s work on the little SUV over the years has resulted in a car that feels mature and capable.

The suspension isn’t perfect, but it manages low-to medium speeds elegantly and does a decent job of maintaining stability at high speeds. It feels better than you’d expect from a car this size on the highway.

The 1294kg kerb weight and small-enough 18-inch wheels mean there’s not too much weight to manage, and there’s enough cushion in the tyres that harsh bumps don’t come crashing into the cabin.

While the CX-3 feels refined for its class, don’t expect a dead-quiet ride, as some road and wind noise make their way in above 80km/h. Then there’s the fact its engine and transmission will sometimes need to get a bit raucous when accelerating quickly. Aside from this, the CX-3 around town and in suburban areas feels nice and calm.

The impressive trick that BMW continually pulls off with its SUVs is giving them the same sensual, muscular steering as its sedans, and an impressively similar ride and handling balance.

The steering is the highlight here, but it's also noticeable how planted to the road it feels.

The X4 speaks to its looks, in fact, by feeling sportier and more alive to drive than you'd expect an X3 to be.  

This is less an SUV for soccer mums and dads, and more a bastard love-child that’s into loud leather and bright neon - a CEO who dressed punk rock-lite on weekends, if you will. 

If those weekends are bereft of child taxiing and loading up the boot with several tons of kid stuff, then you’ll have a blast in the X4. 

A 2018 test gave the X4 a five-star ANCAP safety rating, and an easily located button on the dash brings up the vehicle’s safety suite if you’re the kind of driver who likes to make a few adjustments. 

A 360-degree camera offers multiple viewpoints and is a godsend when parking the X4, since the cabin makes the car feel smaller than it actually is on the outside, and the range of safety features on offer are more than adequate. 

Those include autonomous emergency braking, dynamic braking lights, dynamic stability and traction control, rear-cross traffic alert, speed limit information and hill descent control. 

Mazda offers a five-year, unlimited kilometre warranty, which is behind the curve for a mainstream brand these days. Rival brands like Kia and Hyundai offer seven years, for example, with some offering up to 10.

Servicing is undertaken every 12 months or 15,000km, whichever comes first, with servicing costing between $353 and $633 per visit. Total cost over the first seven years currently sits at $3233, averaging $462 a service, which is pricey considering the relatively simple mechanicals under the CX-3.

Mazda says there are more than 150 certified service dealerships across the country, with a tool to find the most convenient one for you. Given the CX-3’s advanced age, chances are there won’t be too many mechanical issues that haven’t been worked out in the last decade.

Despite all the brouhaha about other car manufacturers offering more generous warranty periods - seven years for Kia, for example - BMW has not shifted its stance, still offering its standard three-year unlimited-kilometre warranty. Frankly, it's just not good enough.

BMW also offer a Service Inclusive package for $2010 that covers owners for five years, or 80,000km.
