Mazda CX-3 vs MG Im5

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 MG IM5 Performance is fast, comfortable, quiet and super refined. Putting some minor spec and active safety niggles to one side, it offers the features, tech and price to match it with its well-credentialled and already popular mid-size EV sedan competitors. Is there room for one more? We think there should be.

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.

Playing spot the straight line on the outside of the MG IM5 is like an automotive design version of Where’s Wally? There aren’t many, in the midst of an unrelentingly curvaceous exterior treatment.

At close to five metres long and two metres wide the IM5 is appreciably longer (+211mm), a little wider (+27mm) and a bit taller (+33mm) than a Tesla Model 3. Think BMW 5 Series in terms of overall size.

And the soft-form shape is functional; the swoopy liftback boasting an ultra-slick 0.24 drag coefficient.

That said, I’m not convinced by the ‘Periscopic’ cameras informing the driver assistance systems from the front guards. They scream tacked-on afterthought. But a touch-only initial opening function for the flush door handles is cool and makes life easier.

The curves continue inside with soft-padded surfaces around the dash and doors, but the straight edge obviously came out for the 10.5-inch central media screen and vast 26.3-inch upper display. There are next to no buttons; even exterior mirror adjustment is directed from the screen to a multi-function steering wheel control.

System software (powered by a Qualcomm ‘Snapdragon’ chip) is lightning fast with a two-finger up and down swipe shortcut function on the central screen for ventilation and other functions.

The interior is light and bright thanks to the enormous panoramic sunroof. It’s been fine in cooler winter conditions during this test but it could be interesting to revisit in the heat of an Aussie summer

There are two interior colour schemes available - the ‘Highland Grey’ of our test car or ‘Dover Beige’ for those brave enough to live life with the threat of scuff marks on your shiny new car’s glamorous but vulnerably light interior.

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.

There’s plenty of breathing room up front and in terms of storage one of the first things worth calling out are the long but relatively narrow door bins. No good for anything above unusually slender bottles, even if they’re lying down.

No conventional glove box in the dash, but there is a large lidded box (cooled and heated) between the seats that doubles as a centre armrest. It’s supplemented by a big stowage area underneath the flying buttress style centre console.  

There are two cupholders in the centre console as well as a wireless device charging pad in front of them with a vaguely phone-shaped oddments bin alongside it.  

Move to the rear and the IM5’s 75mm wheelbase advantage over the Tesla Model 3 is clear. Heaps of knee and headroom for me at 183cm sitting behind the driver’s seat set to my position. 

But… the seat sits low which pushes your knees up into the air to the point where my thighs are not contacting the seat cushion. Even though the rear seat reclines to a certain degree it’s a problem compounded by a chronic lack of room for your toes under the front seat. Awkward.

There are map pockets in the front seatbacks, modest bins in the doors and a fold-down centre armrest with two cupholders. Adjustable ventilation in the rear of the front centre console always makes life in the rear seat more pleasant.

The car also houses ‘Strong Magnets’ at various points around the cabin and boot, with a configurable adapter able to lock a phone or tablet into place for the entertainment of, in our case, back seaters. 

Speaking of devices for entertainment, there are two USB-C sockets and a 12-volt outlet in the front and another USB-C and 12V in the back, so charging isn’t an issue. 

The IM5 is a liftback so the boot aperture is generous and a capacity of 457 litres with the rear seats up is decent for a car of this size, although that’s less than the Tesla Model 3 (594L) which has an additional well under the floor. 

Still, enough room for the largest (124L) and smallest (36L) suitcases from the CarsGuide three-piece luggage set with some room to spare.

The power tailgate can be operated hands-free via the key or an always welcome under bumper kick function.

Volume expands to 1290 litres with the rear seats folded and there’s a modest 18-litre ‘frunk’ under the bonnet.

The bad news is a repair-inflator kit rather than a physical spare wheel, but the better news is the IM5 Performance can tow a 1500kg braked trailer (750kg unbraked).

The IM range also features the ‘MG iSmart’ app allowing remote control of various functions including charging, checking vehicle location and route planning. 

At $80,990, drive-away, the IM5 Performance sits at the top of a three-grade line-up that starts with a 75kWh RWD Premium model at $60,990, followed by a mid-spec 100kWh RWD Platinum for $69,990, both drive-away.

Its most prominent competitor is arguably the Tesla Model 3 Dual Motor AWD ($80,900), with others including the BYD Seal Performance AWD ($68,798), Hyundai Ioniq 6 AWD Epiq ($86,500) and Polestar 2 Long Range Dual Motor Performance ($80,380).

Worth noting, too, the IM6 range - essentially the same car with a taller SUV body - has the same model walk-up and identical pricing.

Once you’ve crossed the $80K threshold it’s fair to expect a decent basket of standard fruit and aside from the dynamic and safety features we’ll get to shortly, the IM5 Performance comes to the party.

Highlights include a double-glazed panoramic roof, power-adjustable (12-way driver, six-way passenger) heated and ventilated front seats (also heated in the rear), dual-zone climate control, 20-speaker audio (with digital radio), 256 colour ambient lighting, a power tailgate (with hands-free function) and 20-inch alloy rims.

There’s also adaptive cruise control, a heated steering wheel, wireless Android Auto and Apple CarPlay, LED headlights, keyless entry and start, wireless device charging (50W), a 10.5-inch central control screen and a sweeping 26.3-inch upper screen; the right side for instrumentation and car data, the (touch-sensitive) left side for multimedia and other onboard functions.

There’s more and it’s clear this car at least matches or betters its direct competitors for included equipment.

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 MG IM5 Performance is powered by an electric motor on each axle - the rear (372kW/500Nm) more powerful than the front (200kW/300Nm), for overall outputs of 572kW (that’s close to 770hp) and 802Nm of pulling power.

The official term for that amount of grunt is… a lot. And we’ll get to what it means on the road in the Driving section shortly.

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 MG IM5 Performance features an 800-volt electrical architecture which means the 100kWh NCM battery can accept a DC peak charge of close to 400kW.

Only snag is the highest you’ll currently find in Australia is 350kW. But even at that rate you’ll still be looking at a 30-80 per cent charge in just over 15 minutes. Maximum AC charge rate is 11kW.

Claimed range is 575km (WLTP) which is less than the Tesla Model 3 Dual Motor AWD at 629km.

Over a week of city, suburban and some freeway running we saw average energy use of 20.6kWh/100km which is on the high side for an EV of this size but maybe not for one with this kind of performance potential. 

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.

First things first, the IM5 Performance is supercar fast. This 2.3-tonne five-seater blazes from 0-100km/h 3.2 seconds and with its dual motors combining to produce 572kW/802Nm, eye-widening performance always resides underneath your right foot.

But it’s not all about straight line speed. Ride comfort is excellent. Underpinned by an all-new platform, the IM5’s suspension is by double wishbones at the front and multi-links at the rear. But the key to its bump and rut smoothing ability is air suspension and ‘continuous control’ active damping.

Fold in double-glazing on the full-length glass roof and side windows, as well as active noise cancellation and you have a serene interior environment at any speed. Also worth noting the front seats are great; as grippy as they are comfortable.

Not only that, despite its relative heft, this mid-sizer steers well, too. Not the last word in road feel but it points accurately and the standard rear steering helps with prompt (but never jerky) cornering turn-in. Flick to ‘Sport’ mode and the IM5 is up for some enthusiastic running.

The rear wheels can turn up to 12 degrees in the opposite direction to the fronts at slow speed, which makes for a usefully tight 10-metre turning circle. But above that, at lesser angles, it adds extra stability and decisiveness in the way the car steers through even tight, twisty sections.

Rubber is top-shelf Pirelli P Zeros on 20-inch alloys (245/40 fr - 275/35 rr) and it grips hard, especially in the wet weather over much of the test period. Braking is solid, as it needs to be, with ventilated discs all around and four-piston callipers at the front. 

No adjustable regen braking but you can feel the ‘Cooperative Regenerative Brake System’ (CRBS) doing its thing when you lift off the accelerator. 

The physical rear view is modest thanks to the slope of the back window reducing its functional area for the driver to that of a 1950s VW Beetle. Even the interior rear-view mirror is tiny and folds up into a recess in the headliner if you’d prefer life without it.

But that’s where a rear camera view popping up on the upper screen display (accessed via the right-hand steering wheel click control) comes in handy. Side camera views are also available as is a 360-degree overhead view, which makes parking straightforward.

If you need more parking help there are various self-parking modes including a nifty ‘Curbside’ function that will realign the car hands-free if you’re parallel parked too far out from the kerb.

In a similar vein, a ‘Rainy Night’ mode projects left and right rear views onto the main screen using AI to enhance clarity and highlight pedestrians and cars.

Overall the ADAS (Advanced Driver Assistance Systems) are relatively unobtrusive but we found ourselves switching off the incessant overspeed chime that sounds for 10 seconds if you creep over the indicated speed limit, even when the system has misfired on the correct speed. For example, 40km/h school zones on a Sunday.

The over-zealous driver distraction warning also occasionally issued a visual and audible slap on the wrist when I was looking straight ahead. Tellingly, there’s a specific quick screen for turning both these functions off, but it kinda defeats the purpose of having them in the first place.

We also found the adaptive cruise control to be hesitant in multi-lane environments, reducing speed occasionally because the system seemingly believed a car was set to merge, when it wasn’t.

No independent ANCAP safety assessment at this point but there’s a full suite of active safety tech onboard including AEB, lane departure warning, blind spot detection, rear cross-traffic alert & braking, forward collision warning, lane-change assist, tyre pressure monitoring and heaps more. And we touch on how it all operates in the Driving section above.

There are no less than nine HD cameras, 12 ultrasonic sensors and three millimetre-wave radars on duty.

If a crash is unavoidable there are seven airbags including full-length side curtains and a front centre bag. Multi-collision brake also minimises the chances of subsequent impacts after an initial crash. There are also three top tether points and three ISOFIX child seats anchors across the second row.

All right on the pace for this part of the market and the IM5’s competitive set.

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 MG IM5 Performance is covered by a seven-year/unlimited km warranty, which is a plus, but the catch is it’s conditional on authorised dealer servicing. Go elsewhere and the term drops to a more common five years/unlimited km. The drive battery is covered for eight years/160,000km, which is the norm in the Aussie market

Servicing is required every 12 months or 20,000km with charges averaging $586 per workshop visit for the first five years, which is on the high side for an EV, even at this price point, the average bumped up by a more than $1400 doozy at year four.

MG IM models are sold (with service available) through all of MG’s 100-plus dealerships across the country, so no concerns there.
