Hyundai Ioniq 6 vs MG Im5

What's the difference?

The Hyundai Ioniq 6 will stand out in any automotive crowd, thanks to its distinctive aero-influenced design.

It’s well-equipped for the money, surprisingly roomy, energy efficient and notwithstanding some niggles around the ride and steering feel, comes up to scratch dynamically.

Does it do enough to apply the thumb screws to the likes of Tesla's Model 3? I think it’s got a pretty good shot, and it will be interesting to see if EV buyers embrace the car’s unusual streamlined look.

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.

Lots of cars are said to be “shaped by the wind” but all you have to do is look at the Ioniq 6 to know that in this case it’s 100 per cent true.

In fact, images of the car in Hyundai’s wind tunnel show it performing more like a perfectly shaped wing than a four door sedan.

With a drag co-efficient (Cd) of 0.21 it’s slicker than the ultra low-drag Tesla Model 3 and Porsche Taycan. And while not conventionally pretty it’s certainly a striking and unusual design.

Flush door handles? Of course. Carefully sculpted spoilers front and rear? Yep. Active air flaps? Check. The RWD Dynamiq’s 18-inch alloy rims are shaped for aero efficiency, while the top-spec Epiq grade even swaps out conventional side mirrors for super-cool digital cameras and interior OLED screens.

And the sleek looks continue inside with a two-section dash divided horizontally by a swoopy winged insert and topped with a pair of 12.3-inch screens covering multimedia and instrumentation.

The look and feel is minimalist. A lot of the controls are on screen or digital, but a physical dial for audio volume gets a big safety and convenience tick. 

No gearshift in the bridge-like centre console. A rotary stalk is located behind the steering wheel on the right-hand side.

There’s configurable ambient mood lighting with six pre-selected themes and the materials used inside are suitably eco-friendly.

Cloth seat trim is recycled PET plastic, as is the headliner, the dashboard skin is manufactured using bio-ethanol, the carpet is made from recycled fishing nets (!), and bio paint (partially derived from vegetable oils) is used on the doors. 

Yes, there’s leather, but its dyeing process uses biodegradable flaxseed oil rather than conventional pigments, which is a good thing in terms of fewer harmful microorganisms in waste water, and is claimed to reduce CO2 emissions by 3.8kg per car. 

On the outside, recycled pigment paint made using ‘end-of-life’ tyres is applied to the body cladding, and bamboo charcoal pigment paint is used in the ‘Digital Green’ pearl colour option.

Speaking of which, there are seven other colours available; three more pearl shades - ‘Abyss Black’, ‘Ultimate Red’ and ‘Biophilic Ink’, as well a single metallic ‘Nocturn Gray’ and a solid ‘Byte Blue’. ‘Gravity Gold’ matt finish is the only extra-cost choice at $1000. 

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 Ioniq 6 is just under 4.9m long and the wheelbase is close to three metres, so no surprise there’s an impressive amount of space inside the car.

A flat floor enhances the roomy feel, plus controls for windows and mirrors are located in the centre console or on the dash rather than the front doors, which has allowed the armrests to be trimmed down for some extra breathing space.

As mentioned earlier, there’s no gearshift in the centre console, either. It takes the form of a rotary stalk on the right hand side of the steering column. It doesn’t take long to get used to and I found it pretty handy to use.

There are large bins in the doors with space for bottles, two cupholders in the console and a medium-sized lidded storage box (which doubles as a centre armrest) between the seats.

A lengthy tray underneath the main console keeps additional loose items under control and a generous glove box slides out from the dash rather than flipping open. So, there’s plenty of storage on offer.  

Move to the rear and it feels like you’ve teleported into the back of a stretch limo. With the driver’s seat set to my 183cm position there is huge legroom.

Hyundai says thanks to the use of high strength steel the backs of the front ‘relaxation’ seats fitted to the AWD models are appreciably thinner than normal, also increasing rear space.

Rear headroom is fine sitting in a normal, relaxed position, although sitting bolt upright my bonse grazes the headliner. 

Three abreast for adults will be okay for short runs, but not a goer for lengthy road trips. Three up to teenage kids will be fine, though.

Speaking of kids, parents will appreciate ‘Quiet Mode’ which limits audio to ‘25’ in front and mutes the rear. Perfect for uninterrupted sleep back there, or keeping the noise to a minimum for those furiously focused on their favourite game or a movie.

Backseaters are provided with bins in the doors, although the section scooped out for bottles is small, there are two cupholders in the fold-down centre armrest, netted map pockets on the front seat backs and a small slot for keys or a phone under the adjustable air vents at the rear of the front console.

Connectivity and power options run to three USB sockets in the front (one Type-A for media and charging, plus two Type-C for power only), a 12-volt socket under the front console, and two Type-C ports in the back. That’s plenty. 

Boot space is 410 litres (VDA), and the rear backrest split-folds 60/40 to liberate more room. Worth noting there are no tie-down anchors in the boot, but there is an underfloor storage compartment, plus a 45L ‘frunk’ under the bonnet of the RWD and a 14.5L storage space in the front of AWD models.

The boot lid is powered but there’s no spare, just a mobility kit. Grrrr!

If you want to hook up the tinny or camper trailer, towing capacity is 1500kg for a braked trailer and 750kg unbraked.

A bi-directional ‘Integrated Charging Control Unit’ (ICCU) allows for ‘Vehicle to Load’ (V2L) functionality on the inside and the outside of the car. There’s a house power-style three-pin outlet at the base of the rear seats or a simple adapter plugs into the charging outlet. Super-handy for camping, picnics, you name it.

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 entry-grade Ioniq 6 is the rear-wheel drive Dynamiq, featuring a 168kW/350Nm permanent magnet synchronous electric motor on the rear axle powered by a liquid cooled lithium-ion battery.

The all-wheel drive Techniq and Epiq models feature an additional permanent magnet motor at the front for a combined output of 239kW and 605Nm.

Drive is fed to the wheels via a single-speed reduction gear auto transmission on the rear or both axles.

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.

All versions of the Ioniq 6 carry the same 77.4kWh lithium-ion Polymer battery and the car’s 800V architecture allows it to use 350kW DC fast charging for a 10-80 per cent fill in 18 min.

The number of genuinely fast chargers available is increasing rapidly and that fill time is impressive.

Drop to 400V (50kW charging) and that time increases to 73 min, while 7.0kW AC charging from 10 to 100 per cent will take close to 12 hours.

The ports behind the not-fuel flap are a Type 2 for AC and CCS Combo2 for higher powered DC charging.

And if all else fails, you’re also equipped with a portable charger/cable so you can access house power for a full charge in, wait for it… 34 hours 20 min.

Quoted WLTP range for the RWD Dynamiq is 614km, that number dropping to 519km for the more powerful, dual-motor Techniq and Epiq models.

The WLTP combined cycle energy consumption figure for the Dynamiq is 14.3kWh/100km, with the Techniq and Epiq models at 16.9kWh/100km.

A ‘Disconnector Actuator System’ (DAS) on the front axle of the AWD grades is able to automatically engage and disengage drive to the front wheels as required, to reduce mechanical drag, lower energy consumption and increase driving range.

On test, in the Dynamiq, over a mix of suburban, b-road and freeway running we saw an average of 16.1kWh/100km which is a pretty good result.

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 the RWD Ioniq 6 Dynamiq will accelerate from 0-100km/h in 7.4 seconds, which is not hanging around, and it feels every bit that quick. 

In fact, it has more than enough performance for sharp response in the city and easy cruising on the highway.

Step up to the AWD Techniq or Epiq and you’re hitting 100km/h in just 5.1 seconds, which is properly rapid. 

A single-speed ‘shift-by-wire’ reduction gear auto transmission sits on the rear or both axles and you have the choice of ‘Normal’, ‘Eco’, ‘Sport’ and ‘Custom’ drive modes, which fine-tune power output, accelerator response, steering weight as well as power distribution between the axles on AWD models.

Hyundai’s ‘E-Active Sound Design’ (e-ASD) changes the ‘sound texture’ as you drive with a noise roughly approximating Luke Skywalker’s Landspeeder coming through the speakers.

It’s fun for a while, but I found myself turning it down, then off, for the majority of the launch drive. And in that silent mode you can feel and hear (or not?) the impact of the car’s super-slippery shape. No wind noise and only modest tyre rumble at 110km/h on the freeway. 

The Ioniq 6 sits on Hyundai’s ‘Electric Global Modular Platform’ (E-GMP) which features the flat battery pack mounted low down, skateboard-style, between the axles. 

Suspension is strut front, five-link rear, and although the set-up hasn’t been tuned locally, Hyundai Australia says it’s been involved in the development. 

The front seat remained comfy after hours behind the wheel, but it must be said bumps and thumps from typical highway surfaces made their presence felt on a regular basis.

That’s not unusual for a full electric vehicle, but with the RWD Dynamiq riding on relatively cushy Hankook 225/55 ventus S1 evo3 rubber, it’s surprising.  

In corners you can feel the effect of the car’s low centre of gravity with the battery and motor(s) mounted low in the chassis. It hunkers down and remains beautifully balanced and secure through sweeping bends.

But even though the car points nicely, a meaningful connection between the front tyres and your hands on the steering wheel is MIA. 

The physical brakes are vented discs at the front and solid rotors at the rear, adjustable through ‘Normal’ and ‘Sport’ settings, and they’re nice and progressive.

However, there’s more fun to be had with the regenerative braking, adjustable through three levels (‘Strong’, ‘Medium’, ‘Soft’) via steering wheel-mounted paddle shifters.

Move to the highest setting and you’re in ‘i-Pedal’ mode which means for the majority of the time easing off the accelerator is all that’s required to wash off speed before coming to a reasonably prompt halt.

In terms of ergonomics, the simple dash layout works well thanks to a sensible mix of digital and physical controls, the head-up display is crystal clear, and the big screens for media and instrumentation are hard to fault.

A word of warning, though. An over-speed chime fires four times when you even marginally exceed the detected limit. It quickly becomes intensely annoying, the saviour being an off button in the vehicle settings menu. Downside is it defaults to ‘on’ every time you stop and re-start the car. Ugh!

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.

Hyundai covers the Ioniq with a five-year, unlimited km warranty, with eight-year, 160,000km protection for the high-voltage battery. Both are industry standard these days.

There’s a lifetime servicing plan with maintenance intervals set at an impressive two years/30,000km. 

At this stage cost is $560 a throw, which is pretty handy when you consider the lengthy service intervals. 

A ‘Premium Roadside Support Plan’ is complimentary for the first 12 months and renewed annually while the vehicle is serviced by Hyundai.

Also complimentary is a ‘Sat Nav Update Plan’ which includes nine updates to be used within 10 years.

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.
