MG Im5 vs Ssangyong Rexton

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.

If KG Group can provide the long-term stability and new model investment that has eluded SsangYong for so long, the brand could have a promising future in Australia judging by the MY24 Rexton Adventure. It’s a solid package and what it lacks in benchmark ANCAP safety and third-row comfort is offset by a compelling driveaway price, generous warranty and national dealer network. So, if you’re looking for a feature-packed 4x4 seven-seater SUV for less than $55K, you might be pleasantly surprised by this competent Korean.

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.

With its 4850mm overall length and 1960mm width, the Rexton rides on a 2865mm wheelbase with a compact 11-metre turning circle.

Its smooth ride comes from four-coil suspension with double-wishbones up front and an independent multi-link arrangement in the rear. For those venturing into the rough stuff, it has 20.5 degrees approach and departure angles, 20 degrees ramp break-over angle and 203mm of ground clearance.

Looks are subjective, of course, but we reckon it has attractive and cohesive styling, with its prominent and ornate diamond-style grille complimented by distinctive side-body contours that can’t be mistaken for other SUVs.

The interior has a premium look and feel, with lots of exposed stitching along soft-touch seams and a tasteful blend of contrasting surfaces including chrome, satin chrome, piano black and textured patterns.

There’s good attention to detail and build quality is excellent, but there are some annoying design quirks like the need for the front passenger to access a touchscreen menu just to adjust the audio volume.

The second-row of seating has a/c vents in the centre console and is spacious even for tall people like me (186cm). When sitting behind the driver’s seat in my position, there’s about 60mm of clearance between my knees and the driver’s seat backrest, which combined with ample head and shoulder room makes for a comfortable ride.

By contrast, the third-row seating is strictly for young kids, as there are no adjustments for the second-row’s backrest angle or fore/aft base cushion positioning to accommodate taller frames like mine. The side windows in the thick rear roof pillar are also conspicuously small, which adds to a claustrophobic feel.

Fortunately, access to the third-row is made easier by the 60/40-split second-row, which can be folded and tumbled forward.

However, given I’ve found tolerable third-row comfort in some rival seven-seaters, the Rexton’s third-row is my only gripe for those with longer limbs.

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. 

With its 2130kg kerb weight and 2960kg GVM, our test vehicle has a sizeable load capacity of up to 830kg, which should be ample for five occupants and their luggage.

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer and its 350kg maximum tow-ball download is compatible with that requirement.

Plus, its generous 6460kg GCM (or how much it can legally carry and tow at the same time) means it can legally tow its maximum trailer weight while carrying its maximum car-load, which is a practical set of numbers for just about any recreational requirement.

Front-row cabin storage includes cup/bottle-holders and a small bin in each front door, plus a single glove box. The stylish centre console has a bin up front with sliding-lid, two cupholders in the middle with another sliding-lid, plus a box at the rear with hinged padded-lid that doubles as a driver’s elbow rest.

Those seated in the second-row get a cup/bottle holder and bin in each door, plus pockets on each front seat backrest. The fold-down centre armrest has two more cupholders and a handy hidden compartment that’s ideal for small items. Third-row occupants get storage bins on each side but no cup/bottle holders.

Accessing the cargo area through the power tailgate reveals 236 litres (VDA) of load volume with the third-row seats upright. This expands to 641 litres with the third-row folded flat and 1806 litres (or more than 1.8 cubic metres) with the second and third-rows folded.

The cargo area’s rear floor has a two-tiered design, with the top floor lying flush with the third-row seats when folded but it can be removed to reveal a lower floor that provides a second level of storage. There’s also a usefully large bin in the right-hand-side wall cavity. The only things missing are sturdy load-anchorage points at floor level to secure cargo nets or straps.

Our test vehicle is the new ‘Adventure’ model, which serves as the middle-grade offering between the entry-level ELX and top-shelf Ultimate.

It’s equipped with the same 2.2-litre four-cylinder turbo-diesel, eight-speed automatic and part-time 4WD as other Rextons, for a drive-away price of only $54,000 (our 'Space Black' metallic paint is a $595 option).

That pricing looks razor-sharp compared with mid-grade 4x4 seven-seaters offered by segment leaders like the Isuzu MU-X LS-U ($61,400), Ford Everest Trend ($66,790) and Toyota Prado GXL ($69,530).

And they are 'list' prices (not including on-road costs) whereas the Rexton is 'drive-away-no-more-to-pay'.

The MY24 upgrades include a new dash layout and high-mounted 12.3-inch multimedia touchscreen with Apple/Android wired connectivity. There’s also a restyled dual-zone climate control hub with touchscreen, plus new lower body mounts for improved ride quality.

The Adventure brings numerous luxuries like a walk-up welcome system (mirrors unfold and puddle lamps illuminate), touch-sensing front door locks with walk-away auto door-locking, power tailgate and soft-touch synthetic leather seats with the fronts offering power adjustment, heating and cooling.

The second-row outer rear seats and steering wheel are also heated, plus there’s speed-sensitive power steering and tyre pressure monitoring.

These appointments are in addition to the base ELX’s generous standard equipment list including 18-inch 'diamond-cut' alloy wheels with 255/60 tyres and a full-size alloy spare, LED dusk-sensing headlights/DRLs/front fog lights/tail-lights, heated door mirrors, a four-way-adjustable leather steering wheel and 12.3-inch driver's digital instrument display.

There are also four USB-C ports (two front and two in second row centre console), three 12-volt outlets (front console box, second row centre console and cargo area), electric parking brake, reversing camera, front and rear parking sensors and more. It's fair to say the Rexton Adventure is feature-packed.

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 quiet and refined 2.2-litre, four-cylinder, turbo-diesel, which meets Euro 6 emissions standards, produces 149kW at 3800rpm and 441Nm across a 1000rpm-wide torque band between 1600-2600rpm. It provides energetic response in city and suburban use.

This engine is paired with an equally refined eight-speed torque converter automatic, with overdrive on its sixth, seventh and eighth ratios ensuring low-rpm operation and optimum fuel economy at highway speeds.

Sequential manual-shifting is available using the steering wheel-mounted paddles and there's a choice of three drive modes ('Power'/'Winter'/'Eco') which can be selected using a console button.

The part-time, dual-range 4WD system is controlled by a console dial, offering the choice of 2H (2WD high-range), 4H (4WD high-range) and 4L (4WD low-range). It also has an auto-locking rear diff to optimise traction as required.

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. 

SsangYong claims an official combined cycle average of 8.7L/100km. At the completion of our 307km test, which comprised mostly city and suburban driving with a bit of highway travel, mostly in Eco mode with up to five occupants on some trips, our figure calculated from fuel bowser and trip meter readings came in at 11.0L/100km.

Although higher than SsangYong’s claim, it was within the usual 2.0-3.0L/100km discrepancy between official and ‘real-world’ figures. So, based on our numbers, you could expect a driving range of more than 600km from its 70-litre tank, which is not bad. Based on the official figure, driving range extends to around 800km.

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 Rexton’s overall refinement and build quality are evident when you get behind the wheel. It offers good adjustability for driver comfort and the fundamentals of the vehicle are sound, as there were no red flags during our test.

The engine is smooth and quiet with good all-around performance, the automatic transmission shifts quickly and smoothly, the steering is nicely weighted and communicative, the brakes provide reassuring response and the ride quality is supple over bumps yet disciplined enough to provide good handling response.

It’s also pleasantly quiet at highway speeds, with low tyre and wind noise. Engine noise is also minimal, given that it requires only 1600rpm to maintain 110km/h, ensuring low-stress cruising.

Most of our driving time was spent in Eco mode, as we found performance in this setting more than adequate for our purposes. We did briefly use the Power mode but didn’t notice any significant change in response.

No ANCAP rating (as yet). Even so, it comes with numerous passive and active safety features highlighted by dual front, side and curtain airbags plus a driver’s knee protection bag (but no centre airbag between driver/front passenger).

There’s also AEB, lane assistance, blind-spot warning and rear cross-traffic alert, trailer sway control, hill descent control, front/rear parking sensors, reversing camera and more, but a notable absentee is speed-sign recognition and the cruise control is non-adaptive. There are also ISOFIX child seat anchorages on the two outer second-row seating positions plus top tethers for all three.

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.

Warranty cover is seven years/unlimited km warranty plus seven years roadside assist.

Scheduled servicing is every 12 months/15,000km whichever occurs first.

The first seven scheduled services run to $375 each, up to seven years/105,000km, for a total of $2625.
