MG Im5 vs Hyundai Imax

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.

It looks a bit old-fashioned in a ‘Tarago’ sort of way and is starting to show its age with a five-speed transmission and in lacking some of the latest safety features. However, if you need to regularly transport up to eight people and expect good comfort, economy, performance, practicality, reliability and warranty as part of the deal, then the iMax still has more than enough going for it to justify top three positioning on any people mover shopping list.

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.

Compared to the Kia Carnival, which looks like tomorrow’s people mover today, the iMax is looking more like yesterday’s as its tall and minibus-like dimensions are immovably defined by its iLoad commercial van birth twin. Even so, there is still plenty of practicality and ease-of-use inherent in this traditional design, including a bright and airy cabin with generous headroom for all.

The iMax rides on the same 3200mm wheelbase as the iLoad and shares many of its key dimensions along with power-assisted rack and pinion steering and four-wheel disc brakes. However, to provide better ride quality than the van’s leaf springs, for human cargo the iMax’s multi-link live rear axle rides on plusher coil springs. The Series II upgrade also includes restyled 16 x 6.5-inch alloy wheels shod with 215/70 R16C tyres and a full-size steel rim spare.

The large front doors open wide for easy entry and exit and with no console between the front seats the driver and front passenger can literally walk through to the passenger area. Sliding doors on each side, with large windows that can be propped open for extra ventilation, allow generous access to the second and third row seating. These bench seats provide ample head room and adequate shoulder and legroom for medium-sized adults, even with three across the back row, which is a refreshing change from many SUVs that treat third-row adults as extra baggage.

There’s also ample ventilation, with roof and floor-mounted air vents for the second and third rows linked to a separate control panel which allows passengers to adjust the fan speed and air-con temperature independent of the driver. Combined with generous headroom and large rear passenger side windows which can also be propped open, the iMax succeeds in minimising claustrophobic feelings particularly for those in the back row.

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. 

The iMax’s hefty kerb weight of 2230kg and GVM (gross vehicle mass) of 3030kg allows for a payload of 800kg and up to 125kg of that can be carried on the roof with a three-rack system. Eight average-sized adults on board would use up most of this payload capacity, so if they need to bring luggage it could easily surpass the payload limit. 

It’s also rated to tow up to 1500kg of braked trailer and with a GCM (gross combined mass) of 4530kg it can carry its maximum payload while doing it. However, you also need to keep in mind that the 150kg tow-ball download limit is included in the total payload, leaving 650kg rather than 800kg to play with. Even so, any vehicle that can tow its maximum trailer weight with a full payload gets a big tick from us, particularly one with a cavernous (VDA) 842 litres of cargo volume available behind the third row of seats.

An impressive array of storage solutions includes dual map pockets and a single bottle holder in each front door, a dash top storage compartment, dual glove box compartments, central dash dual retractable cup holders and an overhead felt-lined sunglass holder. Those seated in the second row get dual map pockets and single bottle holders in each sliding door plus mesh-type storage pockets on the rear of each front seat, while third row outer passengers get storage recesses and cup holders.

Our test vehicle was the premium grade with 2.5 CRDi turbo-diesel four cylinder engine and five-speed automatic transmission at $47,290 plus on-roads, with metallic paint an extra $695.

The Series II upgrade features minor styling tweaks and new equipment including driver and front passenger side (thorax) airbags, driver-front passenger climate control, an upgraded 7.0-inch touchscreen multimedia interface with connectivity including Bluetooth, 'Siri Eyes Free' (iOS) and 'Google New' (Android) but no Apple CarPlay, electric folding door mirrors, premium steering wheel and gear-knob, rear view camera and cruise control (on diesel auto only).

These upgrades boost what was already a well-appointed package including numerous passive and active safety features, tilt-adjustable steering wheel with audio controls, one-touch power front windows and a 12 volt dashboard power outlet to name a few.

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 iMax shares the same 2.5 litre common rail four cylinder turbo-diesel found in the iLoad and it’s just as well suited to moving people as it is to shipping heavy cargo. With 125kW at 3600rpm and a bountiful 441Nm of torque peaking at 2000-2250rpm, this refined and torquey engine uses its variable vane turbocharger (VGT) to good effect with great flexibility through the rev range.

The five-speed automatic with sequential manual shift option is the only transmission available with this engine and they are well matched. The torque converter’s stall speed and low 3.730 first gear combine with the 2.929:1 diff ratio to provide lively response from standing starts, making it well suited to stop-start city and suburban duties. The overdriven fifth gear allows economical cruising at highway speeds.

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. 

Hyundai claims a combined figure of 9.0 litres/100km but our numbers based on trip meter and fuel bowser readings came in at 11.8L/100km. Based on these ‘real world’ figures expect a fuel range of around 640km from its 75-litre tank.

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.

Impressive comfort, refinement and low NVH (noise, vibration and harshness) levels ensure the task of moving people is not a chore. The iMax is well designed for its specific role in life and gets the job done with a minimum of fuss. Loads varied from driver only up to six adult passengers during our test.

Although fitted with rear coil springs the tail stills feel a bit jittery over smaller bumps.

In city and suburban traffic it’s a surprisingly agile and energetic performer that belies its 2.2 tonne-plus kerb weight, with nicely-weighted steering, responsive braking and a sharp 11.22 metre turning circle.

Although fitted with rear coil springs the tail stills feel a bit jittery over smaller bumps and road irregularities when empty or lightly loaded, as those thick coils are designed to cope with a GCM of more than 4.5 tonnes. In other words, ride quality is at its best with a decent load on board.

Wind, tyre and engine noise are well suppressed. The resulting low cabin noise is a big bonus, particularly at highway speeds where conversations between front seat passengers and those in the third row can be conducted at normal voice levels. Along with its comfortable bench seating, this quietness makes longer journeys less tiring and more engaging for all passengers no matter where they’re seated.

Driver and front passenger comfort is excellent with all controls and dash contours thoughtfully placed.

The iMax’s tall highway gearing results in only 1800rpm at 100km/h and 2000rpm at 110km/h where maximum torque also resides. Driver and front passenger comfort is excellent with all controls and dash contours thoughtfully placed, plus supportive seating with inboard fold-down armrests. Those front seats provide a commanding view of the road and all external angles thanks to large door mirrors and a rear view camera.

Our only major gripes are that in wet weather the swept area of the left-hand wiper leaves the front passenger with more than half of their forward view obscured by unswept glass. It also shares the iLoad’s terrible static interference on AM band radio at times. And one iLoad feature we would like to see shared with the iMax is its automatic central-locking mechanism which locks all doors when vehicle speed exceeds about 5 km/h

The iMax falls one star short of the maximum five-star ANCAP crash safety rating. Even so it’s equipped with numerous passive safety features including front (and now) side airbags for driver and front passenger, full lap-sash seatbelts and head restraints for all passengers, ISOFIX child restraint anchorage points for the two outer seats on the second row and three top-tether child restraint anchorage points.

There’s also the usual electronic active safety features including brakeforce distribution (important for load luggers), rear parking assist and rear view camera with guidelines, but no auto emergency braking (AEB), blind spot detection or collision alert.

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.

Standard warranty is five-year/unlimited km, with scheduled service intervals of 12 months or 15,000km, whichever comes first.

A capped-price servicing scheme is in place, with $349 the standard rate ($499 for 60,000km service only).

Roadside Assist is complimentary for the first 12 months, plus there's an optional Roadside Support Plan for up to 10 years, 'Lifetime Service Plan' and 'Sat Nav Update Plan'.
