MG Im5 vs Mazda CX-80

What's the difference?

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.

The Mazda CX-80 Touring G40e will do everything you ask of it and outside of pricey ongoing costs, there’s not much to annoy. It’s too large for my small family of three and if it’s kid stowage that you’re looking for, a people mover might offer better practicality and comfort than what this does. Would it be a model that you jump through hoops to get? Maybe not, but it still has a place as family hauler and is easy to drive.

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.

I've said it before but Mazda SUVs all look like scaled versions of each other to me and the CX-80 looks ridiculously similar to every other larger SUV model in the Mazda stable with the long pronounced nose that features sharp LED lighting and its general robust size.

The rear is where it differs with the proportions becoming a little bulbous but it’s practically shaped and overall is a nice-looking family SUV at the kerb side.

Head inside and the interior is pleasant with its high-quality trims and heavy-handed styling that matches the exterior dimensions with big panelling and air-vents up front to balance out the long width of this dashboard.

However, the whole car tends to lack personality for a model that’s a part of Mazda’s ‘premium SUV’ range. It's nice but doesn't add anything new.

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. 

Seven-seat SUVs tend to really be a 5+2 combo, where the rear two seats are for kid- or emergency-use only. You'll be pleased to find that all passengers enjoy a decent amount of space in each row in the CX-80. The third row is still a little cosy for an adult but my 6ft2 brother managed to get back there without too many grumbles. However, we all giggled as he sort of fell in due to the lack of handholds (sorry, Mack).

Otherwise, the 170mm ground clearance and wide door apertures make it an easy SUV to get in and out of. The doors are heavy and sometimes miss their 'hold' position if you open them too quickly, making them swing back. My eight-year-old got whacked a few times because of it!

Amenities and storage are best in the first and second rows with front occupants enjoying those heated seats, two USB-C ports, a 12-volt socket and wireless charging pad. You also get dual-zone climate control, and powered seats with adjustable lumbar support. The seats are well-padded but fairly narrow and short in the base, making it easy to fatigue on longer journeys.

Storage includes a large glovebox that can hold a manual and a fair bit more, a shallow but handy middle console because of its dual-opening lid and a total of four drink holders. There's a sunglasses holder but not much else for smaller loose items.

In the second row you get two map pockets, a small storage bin in each door and a total of six drink holders. There's also individual reading lights, two USB-C ports, climate control, directional air vents, a fold-down armrest and retractable sunblinds (always a winning feature in my house).

The third row gets four drink holders, two USB-C ports and two directional air vents.

Feedback from my passengers (kids and adults alike) hasn't been great for the air-conditioning system with all complaining how long it took for the rear two rows to cool down. The low and awkward positioning of the air vents also prevents direct air flow to passengers. The third row is impacted by this as the passenger's legs cover them.

The rest of the technology is solid with the multimedia system offering a rotary dial operation. The system hasn't seen any recent updates, so if you're familiar with the Mazda system, you'll get along just fine.

The built-in satellite navigation is simple enough to use and the wireless Apple CarPlay is easy to connect to. There's also wireless Android Auto. Call connections remained consistent but feedback was that there seemed to be a fair bit of background noise on my end during calls.

Rounding out the interior is the boot space which offers a level loading space, retractable cargo blind and underfloor storage which houses the tyre repair kit. There's also a 12-volt socket and 220-volt/150W AC socket housed on a side panel.

With all three rows up, you get 258L of capacity and that figure jumps up to 566L when the third row is stowed. The CX-8 offered more boot space but the CX-80 is still respectable for the annual family road trip. Plus you get a powered tailgate function in the Touring model, which is always appreciated.

Mazda offers a choice of five CX-80 grades and for almost all of them, you get the option of a new mild hybrid petrol or diesel, or a plug-in hybrid powertrain.

The Touring G40e model on test for this review is second-from-the-bottom and has a petrol mild-hybrid powertrain. It is priced from $61,950 before on-road costs and the Artisan Red Metallic paintwork our test model has adds $995 to the price tag.

The Touring is more affordable than some of its rivals, including the Toyota Kluger GXL at $70,440 MSRP and Hyundai Santa Fe Elite at $62,500 MSRP. However, these two models are full hybrids and the Santa Fe has a slightly longer features list for only a little bit more money which makes it better value overall.

The great thing about Mazda is once you move up from the entry grade, you often benefit from a host of great standard features that would usually come as part of a package or cost extra with other brands. For example the Touring gets leather upholstery, heated and powered front seats and a wireless charging pad, which isn't too bad for a grade that sits towards the start of the range.

There are some solid practical features like the keyless entry and start, rain-sensing wipers, dusk-sensing headlights, powered tailgate, three-zone climate control, retractable sunblinds (second row) and 360-degree view camera system.

Tech feels well-rounded with a 10.25-inch multimedia system, six USB-C ports, two 12-volt sockets, a 220-volt/150W AC socket, satellite navigation and wireless/wired Apple CarPlay and Android Auto.

In terms of value within the CX-80 range, the Touring G40e is the pick of the litter.

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.

 The CX-80 Touring G40e model has an eight-speed auto transmission and all-wheel drive via a 3.3L turbo-petrol in-line six-cylinder engine coupled with a 48-volt mild hybrid system that produces up to 209kW of power and 450Nm of torque.

It’s not ridiculously powerful but pick up is great and there's more than enough to move the CX-80's big body around and support a 2500kg braked towing capacity.

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 Touring G40e model has a 74-litre fuel tank and an official combined fuel cycle usage of 8.4L/100km, which gives you a theoretical driving range of up to 880km.

The mild-hybrid system works well enough that I didn’t hit double digits for fuel usage despite not being shy on using the power while hauling cargo and people on a mix of open road and urban trips.

My real-world use popped out at 9.3L/100km and while the diesel variant has much more efficient outputs and range, this result is pretty good for such a massive SUV.

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 Touring G40e model is pleasant, if a little boring, to bum around in. Boring may be too strong a word but there's not much that gets you excited about the driving experience. The Touring performs and has decent power through most situations but it lacks a certain edge. It's not particularly sporty, nor does it sound mean when you put your foot down.

It's nice and does what you expect it to do.

The ride comfort is good with cushioned suspension with enough road feedback but people in the back will jostle a bit over the worst of the bumps.

Road noise can creep in at higher speeds and third rowers will struggle to be a part of the conversation but overall the cabin is refined for longer journeys.  

Visibility is mostly good because of the big windows but the wider pillars mean I check my blind spots very carefully, as the side mirrors seem a tad too small for the bulk of the car.

The CX-80 has a small turning circle of 11.6m and most of the time it never feels like it lumbers, but when you’re manoeuvring it in a tight car park the steering can feel heavy and a three-point turn starts to feel clumsy.

A saving grace is the excellent quality of the 360-degree camera system which takes out some of the puff from parking it. The CX-80 fills a space and it’s one you'd be careful to park so you don't get crowded.

At the time of this review the new Mazda CX-80 hasn’t been tested with ANCAP and is thus unrated but it has 10 airbags which is great for a big family SUV and includes side-chest airbags for the second row and curtain airbags that extend to the third row.

The Touring G40e model features a robust list of standard safety features including auto emergency braking (AEB), safe exit assist, front and rear cross-traffic alerts, blind-spot monitoring, driver attention alert and monitoring, forward collision warning, lane keeping aid/departure, front and rear parking sensors, a 360-degree camera system, traffic sign recognition, intelligent seatbelt warning and a tyre pressure monitoring system.

The adaptive cruise control is one of the most user-friendly I’ve sampled recently and other than a sensitive lane keeping aid, all systems follow that user-friendly vibe.

There are a total of five top-tether points and two ISOFIX child seat mounts. The width of the middle seat means you should be good to fit three child seats side by side if they're not too large.

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.

The CX-80 is let down a bit by its ongoing costs.

Mazda offers the CX-80 with a five-year/unlimited kilometre warranty which is fairly standard. A number of its rivals are offered with up to seven-year terms these days.

You get a five-year servicing program with services averaging $694, which makes it on the more expensive side, but servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
