Mazda CX-3 vs Smart 3

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.

The #3 Brabus is very nearly one of the great bargains of 2024, with the sort of style, luxury, features, performance and grip you’d expect from the much-more-expensive GLA AMG 45. It’s that good.

What would make it great is a sunblock for the hot glass roof on a sunny day, Australian road tuning for the infuriating ADAS tech and a revised steering tune that didn’t make it feel inconsistent at times.

See past these, though, and the #3 Brabus exceeds expectations.

We’re glad Smart is back.

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.

Smart says Mercedes designed the #3 and it shows.

In silhouette, or when glanced peripherally, it could be the love child of the A-Class and EQA. Only the friendly face betrays its non-Benz heritage.

Longer and wider than the #1, it is also 80mm lower – achieved via a lower ride height, flatter seats and a thinner floor.

Helped by a 35mm wheelbase stretch, it provides a nicely-balanced and proportioned crossover, with a decent drag coefficient of 0.27. The Brabus’ big wheels also fill out the arches very nicely.

Key length/width/height/wheelbase dimensions are 4400mm/1844mm/1556mm and 2785mm, respectively.

Unusually for a coupe/crossover mash-up, there’s slightly more room inside compared to the upright donor model.

Let’s take a longer look in there.

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.

On first approach, you ask yourself whether the #3 is a crossover or a small-to-medium SUV. The low roof and cool frameless doors certainly suggest the former, as do the comparatively small apertures.

That said, with the windows down, those sash-less doors help entry and egress.

Once ensconced inside a long if slightly narrow cabin, the #3 offers ample room for even the tallest adults up front, as well as a reasonably spacious back seat area, though you’d call that more of a '2+1' seater given the lack of girth for three. Most folk shouldn’t struggle to find the right driving position, either.

Presumably keen to impart a generic Mercedes vibe, the #3’s interior is somewhat reminiscent of a GLA’s, albeit from last decade – down to the pronounced T-shape dash featuring a trio of circular vents in the middle, a standalone screen above and (unconvincing) metal-look plastic trim below.

Understandably, like so much of the Brabus, this might appeal to aspiring A45 AMG owners, but it seems oddly dated, given the advanced electrification going on underneath.

Likewise, none of the minimalism cleverness of the ForTwo city-car original is referenced, even digitally. A lost opportunity, really. The OG Smart is an icon.

Meanwhile, ahead of the driver, a narrow digital strip looks twee and cheap, as if ripped from a Japanese 'Kei' car. It’s a strange design detail for a $71K SUV.

Still, the #3’s cabin layout is largely a success, and much of that is due to the first-class quality and finish. Unlike some of the aforementioned Benzes of the previous decade, squeaks and rattles are notable by their absence.

Depending on your body, the racy sports seats up front are either perfectly bolstered or far-too snug, but they provide a decent level of comfort and support. And they position you just right for controlling the centre display, which dominates all.

The 12.8-inch touchscreen feels slick, responsive and right-sized for the car. At first, it can also seem like info-overload and perhaps a bit cheesy with its animal animations, but real thought has gone into it to provide an extraordinary level of functionality.

Across the top are icons for access to media, sat-nav, apps and camera view settings, while the bottom row is for various climate and trip info. While somewhat logically presented, the charging-station list seemed outdated and/or at-times incorrect in our test car.

Mercifully, the Smart has a row of short-cut buttons for 'Vehicle Modes' (including turning off the infernal lane assist and one-pedal accelerator/braking), 'Driving Mode' ('Eco'/'Comfort'/'Sport'/'Brabus'), glass demisters, climate and display-off.

Annoyingly, the latter is closest to reach, revealing the #3’s left-hand drive market bias, as the driver must stretch across to access the first two (and more important) settings.

There are also several handy screen-activated modes including 'Entertainment Mode' that temporarily leaves the accessories and climate control on; 'Rest Mode' reclines the driver’s seat down flat and dims the interior lights; 'Energise Mode' is designed to pep you up; and 'Pet Mode' keeps a climate-controlled atmosphere while deactivating all buttons that a stray paw might press. Clever.

There’s lots more besides, and using the touchscreen is better in this than most other Chinese vehicles, but it remains fiddly and distracting.

It’s also worth pointing out that the fixed glass roof needs a blockout for Australia. A Smart spokesperson said an aftermarket cover is available, but as supplied to us, sitting under it over a run of hot days is almost unbearable without a hat. This is not good enough.

Thankfully, the other basics are all A-OK.

The climate system coped well the hot sun bearing down through the glass, plenty of useful storage makes up for the disappointingly shallow glove box, while the chilled centre console and massive door bins proved especially handy.

USB access is easy, the wireless Bluetooth/Apple CarPlay performed more consistently than in any recent test vehicle and the standard Beats audio brings brilliant sound.

Out back, most people under 180cm should at least avoid scraping that glass ceiling, and there’s a reasonable amount of room for boots and long knees if the front occupants are sympathetic, but you’d be stretching the truth calling the rear seat packaging SUV-esque.

On the other hand, it’s beautifully presented, boasts a comfy and supportive backrest/cushion for outboard passengers and even a do-able centre pew for shorter-distance riders.

And it provides every expected amenity, including air vents, USB-C ports, door storage, a folding centre armrest with cupholders, and overhead handles/lighting/coat hooks.

And while we’ve already complained about the glass roof, it floods the cabin with light, to make it seem airier than it is. Narrow front seats with a see-through slit further enhance this feeling.

Further back, the 370-litre boot is reasonably long and surprisingly deep thanks to a removable upper floor that’s good for stuffing the optional home charging cables in.

And, of course, it can be extended to 1160L via the split-fold backrests to provide extra loading practicality. And there’s even a small (15L) amount of storage under the bonnet.

Maximum towing capacity is 1600kg for a braked trailer.

Though originally brought to market by Mercedes, Smart was never pitched as a premium brand, as it is now.

Back in the late ‘90s, Smart was an early attempt at better urban mobility. The ForTwo was a tad over 2.5 metres long by 1.5m wide and 1.5m tall.

Today, the #1 and #3 share their modular EV platform with Geely’s other small crossovers, including the Volvo EX30 and Zeekr X, while a stretched version underpins the related Polestar 4.

While the #1 starts from a sharp $54,900 (all prices are before on-road costs) for the Pro+, at the other end of the spectrum, the #3 Brabus flagship, with dual motors for all-wheel drive (AWD) and Porsche 911-style acceleration, will set you back $70,900.

Not bad, given it also includes a body kit, extra driving modes, beefier suspension, stronger brakes and retuned traction controls.

Now, that might sound steep against the growing choice of more-affordable EV alternatives out there, but consider that most of the cheaper ones are significantly slower, less sporty and/or not as highly equipped, including the Hyundai Kona Electric, Jeep Avenger and Mini Countryman.

The #3 Brabus’ fiercest foe, the bestselling Tesla Model Y in top Performance guise, is more powerful but costs $12K more and is slightly slower from 0-100km/h.

The $70K Volvo EX30 Twin Motor Performance Ultra costs $1K less and matches the Smart performance-wise as they share the same tech, but it’s considerably smaller.

Meanwhile, the closely-related Zeekr X is $6K cheaper but looks bizarre and is still largely unknown in Australia. At least Smart has that long-time Merc association to fall back on.

In fact, it is distributed by the latter’s biggest dealer group globally, LSH Automotive.

Speaking of which, how does the #3 Brabus stack up against the similar Mercedes EQA and other luxury EV rivals? The less-powerful Merc 250+ is $14K more, has less kit and is nowhere near as powerful. Same goes for BMW iX2, Lexus UX300e and Volvo C40 Recharge (alias EC40).

The #3 Brabus seems to be in a goldilocks zone of premium, performance EV SUVs. The most expensive Smart offers thoughtful value for money. For a change, the car actually lives up to its name.

Predictably, it’s also well stocked, with matrix LED headlights, electric heated/vented front seats, a 12.8-inch touchscreen, head-up display, 640W Beats audio, a foot-actuated powered tailgate, 360-degree camera views, the full advanced driver-assist safety enchilada, auto parking assist, 20-inch alloys and a panoramic glass roof.

Unfortunately, fitted on every Smart, that last one does not come with a factory built-in sunblock, which is completely unacceptable under our hot Australian sun. And no crossover or SUV should be without a spare wheel, either.

These are the #3’s only real deal-breakers.

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.

The #3 Brabus employs one permanent magnet synchronous electric motor per axle, for dual-motor, all-wheel drive performance via a single-speed ‘transmission’. 

They provide plenty of poke, totalling 315kW of power (115kW front, 200kW rear) and 543Nm of torque (200Nm front, 343Nm rear).

Tipping the scales at 1910kg, this means the Brabus delivers an impressive power-to-weight ratio of 165kW/tonne – enough for it to scoot from zero to 100km/h in 3.7 seconds, on the way to a 180km/h top speed.

To put those figures in perspective, the similarly-priced VW Golf R only manages 156kW/tonne and 4.8sec to 100.

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.

All #3s headed to Australia for now are fitted with the larger of the two battery packs available – a 66kWh lithium nickel cobalt manganese (NCM) item.

In the Brabus, it is rated to average up to 415km of WLTP-certified range, which is between 20-40km shy of the mid-spec Premium version.

Smart says the WLTP average energy consumption is 17.7kWh/100km. Our 3000km-old test car’s trip computer displayed a life-cycle average of 14.6kWh/100km since delivery.

During our week with the Brabus, we managed an average of 19.4kWh/100km, and that was over a 95km period of sustained highway driving at 114km/h with cruise control on and climate control set at 18 degrees (to combat the radiant heat from that glass roof).

With a big 22kW AC charger and 150kW DC charger capability, the former will replenish that 66kWh battery in about 32 hours using a home plug or 10 hours with an optional 7.0kW Wallbox, while the latter will need just over an hour from 10-80 per cent with a common 50kW DC charger.

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.

Whatever notions ‘Smart’ might evoke, the #3 Brabus obliterates them. This is no buzzy little city-car runabout, but a surprisingly mature and athletic driving machine. This is a seriously rapid performer.

A trio of driving modes give you a hint of what you’re in for. Eco is lightness and fluff. Not very Brabus, but smooth and calm enough for relaxed commuting. And it’s far from slow, scooting off the line with zip and zest. Enough for most.

Comfort is actually a good all-round setting to be in, with an eager yet controlled level of performance. Strong acceleration and instant accelerator reaction show you mean business – if you’re in the mood. Still civilised and serene otherwise.

Sport ups the ante, as you’d expect, providing a decent whack of speed and immediate response. Actually, this is enough to keep up with most sports car costing thrice the price, while maintaining the driver-assist safety net. Fun without the fear.

Brabus mode is off-the-leash fury, turning the #3 into a convincing AMG alternative thanks to blistering thrust and a powerful punch across the spectrum. More (artificial) noise, more drama, more speed, more fireworks. The 'Launch Control' pins you to your seatback.

Yet even in the latter setting, the Smart behaves with a maturity beyond the brand’s reputation, capable of quick corners with exceptional (AWD-enhanced) body control and roadholding grip, without a punishing ride.

Underneath, a unique suspension tune for the MacPherson-style struts up front and multi-link rear end keep the Brabus hunkered down more effectively at speed.

And even in pouring rain, there are no complaints about the Brabus’ assured and confident handling. Yes, the suspension is firm, but it’s far from uncomfortable, so, an acceptable trade-off.

Plus, though not strictly one-pedal driving, the regenerative braking pressure is enough for slowing down and speeding up in the ebb and flow of traffic in its strongest mode.

Where we’re less happy is in the #3’s steering. It brings three weight modes to the table – but only two are useful, 'Light' and 'Standard'. Super-easy yet not totally devoid of substance, Light is great for around town and general commuting.

But when you lean on it at speed, the steering, whilst crisp and reactive, is not always linear in feel or motion, especially when accelerating at the same time, as you might when coming out of a fast corner.

Depending on how hard you are on the accelerator, there can be a visible step when turned from the straight ahead that can be quite disconcerting. It’s a bit like when slurping in a lumpy bit in a smoothie.

So, what about 'Sport' mode? Here, the steering is just as described above, but with added weight and not much more. Not worth it. Best is Standard mode.

Another disappointment is the advanced driver-assist safety (ADAS) tech’s state of tune. It’s in a state, literally.

The intrusive and apparently non-permanently switch-off-able lane-keep systems, especially, end up resisting what the driver intends, and even fight to steer the car where it thinks it needs to be. This is frustrating and potentially dangerous.

It’s been reported that Geely, and not Mercedes, undertook the development of these ADAS systems. We’re getting sick of (mostly Chinese) manufacturers rolling the arm over and imposing this sort of nannying and ultimately counter-intuitive driving interference tech.

This needs to be fixed. It stops the #3 Brabus from being a great performance bargain.

The #3 range scores a maximum five-star ANCAP crash-test safety rating. It managed high-80s to 90 per cent in all disciplines – Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User and Safety Assist systems.

A full suite of ADAS is fitted, from Autonomous Emergency Braking (operable from 5.0-150km/h car-to-car) with junction, cross-path, pedestrian, cyclist and motorcyclist detection (5.0-85km/h), lane-keep assist (from 65-180km/h) and cross-traffic alert (front and rear), to blind-spot warning and traffic-sign recognition tech.

You’ll also find adaptive cruise control (with stop/go function), highway and traffic jam assist, automatic parking assist, front and rear parking sensors, 360-degree camera and adaptive high beam assist.

Included, too, are seven airbags (dual front, side chest, side head and front-centre), along with two ISOFIX child-seat fixtures and child-seat anchorage points in the back seat.

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.

The #3 offers a (decidedly-average) five-year or (disappointing) 130,000km warranty, whichever comes first. There is also roadside assistance available for free during this period.

Given other EV manufacturers are going seven and even 10 years in the case of MG, with most including unlimited kilometres, this could be better.

Scheduled maintenance is every 12 months or every 20,000km.

Smart provides a pre-paid four-year/80,000km service plan for $3120, which comes to $780 annually. This seems quite expensive for an EV, even a premium one.
