What's the difference?
Mazda calls the new CX-70 its "flagship" five-seat SUV, which also makes it yet another flag-bearer for the brands relentless push up market as part of its 'Mazda Premium' strategy.
It might have a different badge, but it's really a five-seat version of the brand's biggest and most expensive offering, the seven-seat CX-90.
And, for reasons that will become clear in a moment, it's something of a bargain, at least in the context of Mazda's plush large SUV range.
How so, you ask? Read on.
Yep, it’s like deja vu all over again! Yet another fresh name in the Aussie new-car market, but this time in the form of a sub-brand from a carmaker that itself feels like it’s only been around for five minutes (but has in fact been in market here for a decade or more).
We’re testing the MG IM5 Performance, the IM badge standing alone in other markets. There, as here, signifying a new level of equipment, performance and quality.
And we’ve been steering this top-spec, dual-motor AWD version of the pure-electric, five-door liftback IM5, priced and specified to challenge a rapidly expanding group of high-performance mid-size EV sedans now occupying local showrooms.
So, read on to see if this premium electric performer has what it takes to tempt you into a new option from the latest challenger brand to jump into the ever-intensifying, no-holds barred contest for your new-car dollars.
For mine, the CX-70 is the pick of Mazda's premium SUV range, and if you can survive without a third row of seats, it's significantly cheaper than its CX-90 twin, too.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
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.
Yes, the Mazda premium SUV range can look a little same-same, but Mazda insists there are critical differences.
That said, if you can immediately spot the difference between the CX-70 and CX-90 without taking a peek inside, you're doing better than me, given it is the same exact dimensions as Mazda's three-row flagship.
Sure, Mazda talks about things like this design being a “passion pursuer” that serves up "dignified performance” – all of which sounds utterly ridiculous – but the less marketing-speak version is that it looks like a shapely large SUV that ditches the boxy dimensions of a proper 4WD for a more sleek and swooping profile.
Inside, it's a plush and premium-feeling space, with lovely cabin materials, plenty of tech, and plenty of space.
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 CX-70 measures a substantial 5120mm long, 1994mm wide, and 1745mm tall, and it rides on a 3120mm wheelbase.
It will tow 2.5 tonnes no matter which engine you choose, and the expansive boot will swallow between 589 litres and 2015 litres, depending on how you configure the backseat.
All of that space translates to a hugely airy backseat experience, with the second row able to be fixed in a position that either prioritises leg room or boot space.
With the former, you've got tons of space in the second row. I'm 175cm, and my knee and leg room was ample, with only the intrusive tunnel that runs down the middle-centre of the cabin eating into leg room for the middle passenger.
There are also air vents and temp controls, twin USB charge ports, seat heating in the window seats and swathes of very nice materials.
The boot is massive, too. I can't even reach the back of the rear seats when I lean into it, and Mazda says it will swallow smaller surfboard or SUPs without needing to resort to roof racks.
Under-floor storage adds a bit more security for precious items, too.
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.
We'll drill down on this a little more in the practicality section, but it's important to note here that the CX-70 is the same size as the CX-90 – both are 5120mm long, 1994mm wide and 1745mm high — which means the only real difference between the two models is the third row of seats in the CX-90.
And, as it turns out, that's a very expensive pair of chairs. The CX-70 starts with the GT trim at $75,970 before on-road costs for the petrol or $77,970 for the diesel, and then climbs to the Azami trim, which is $82,970 or $84,970.
The CX-90, though, is $82,577 or $85,785 for the GT, or $91,461 or $93,030 for the Azami.
That makes the CX-90's third row at least a $6600 option, but as much as an $8000 upgrade. Mazda has made moves to address this, with a drive-away "plate clearance" that closes that gap, but we suspect those offers will become permanent fixtures to make the jump from 70 to 90 less ferocious.
Anyway, Mazda has thrown just about everything they've got at the CX-70. The GT kicks off with plenty of high-end gear, including 21-inch black alloy wheels, adaptive LED headlights, a panoramic sunroof and a handsfree powered tailgate.
Inside, there are twin 12.3-inch screens with Apple CarPlay and Android Auto, a 12-speaker Bose stereo, leather seats that are heated front and rear, three-zone climate control and a heated steering wheel.
The Azami then adds things like ambient lighting, black Nappa leather seats, which are now ventilated in the front, footwell lighting, body-coloured wheel arches and lower cladding and body-coloured door handles.
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.
You can have one of two engines in the CX-70, with the cheapest being a 3.3-litre, six-cylinder turbo-petrol, producing 254kW and 500Nm. There's also a 3.3-litre, six-cylinder turbo-diesel, making 187kW and 550Nm. Both are equipped with a 48-volt mild hybrid system to marginally reduce fuel use.
All models are AWD, and pair with an eight-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.
Petrol-powered cars will sip 8.1L/100km on the combined cycle, while the diesel drops that to 5.4 litres.
Both models get a 74-litre tank, meaning a theoretical driving range of around 900kms in the petrol, and almost 1400kms in the diesel.
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.
Interestingly, the CX-70 has been tagged as the expected smallest seller of Mazda's premium SUV range, but I reckon it just might be the pick of the bunch.
Every one of the CX-0 models (60, 70, 80 and 90) all get slightly different suspension tunes, and while you can find harsh edges in the other models, the CX-70 feels utterly composed and refined, at least on the smooth-ish roads of our launch test route.
Perhaps most surprising, though, is the CX-70's ability to hold its own on a properly twisting road. We expected lots of weight transfer and the high-pitched sounds of tyres screaming out in pain, but instead found Mazda's massive SUV served up grip, composure, and very little in the way of sea-swell-style body roll.
The two big six-cylinder engines also feel perfectly suited to a vehicle in this space. There's tons of power whenever you need it, and solid levels of refinement in terms of engine noise or diesel rattles.
For mine, the petrol engine is the pick though, feeing just a little smoother than the diesel option. The latter can feel a bit jerky at slower speeds, whether that's the power delivery or the gearbox, and it doesn't seem to happen with the petrol engine.
The biggest caveat, though, is that we haven't driven the CX-70 in its natural environment, the city and suburbs, so while it largely shone on flowing country roads, how it performs on roads like the ones near your place remains a bit of a mystery.
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.
The CX-70 hasn’t been ANCAP tested, but it does arrive with a pretty stacked safety offering, including a 360-degree-view camera, blind-spot monitoring, front and rear cross-traffic alert, and a total of eight airbags, including a knee airbag for the driver.
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.
Servicing is not particularly cheap in the CX-70, and the service intervals, at least in the diesel, feel a little short, too.
Buy that one, and you’ll be visiting the dealership every 12 months or 10,000kms, and the first five years of ownership will cost you $3298.
Petrol cars require servicing every 12 months or 15,000kms, and five years will set you back $3436.
The CX-70 is also covered by Mazda's five-year, unlimited-kilometre warranty.
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.
