Hyundai Sonata vs MG Im6

What's the difference?

The updated Sonata N Line looks beautifully modern from its new face to the refreshed cockpit, while remaining a ‘driver’s car’ with good dynamics, and a sporty engine. 

The Sonata isn’t an ideal family car, however. This is down to a lack of practicality. Although the cabin is fairly roomy, if that roofline wasn’t so coupe-like and cabin storage was better, and the boot had a large hatch opening, and the ride height was more elevated then it would be a great family car. Oh, I’ve just described an SUV.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.

So, we’ve established that the Sonata N Line is a sedan and that means if you’re still reading this you are, a) A Sonata owner looking to trade the old one in for this new one, b) Driving another type of sedan such as a Toyota Camry or Volkswagen Passat and looking to update your trusty steed with one from Hyundai or c) Not in the market for an SUV.

Whatever the reason, sedans lend themselves to being sleek and sophisticated in their styling just by being lower to the ground than SUVs and generally longer than sports cars.

The Sonata N Line is long at 4.91m end-to-end. That’s only 8.0cm shorter than the gigantic Hyundai Palisade which has eight seats. I know… it bends the mind.

This new Sonata N Line looks even wider than the previous version, too, with that broad flat bonnet meeting the Seamless Horizon LED strip.

Fact is the Sonata N Line is 1.86m across - exactly the same as the previous version. Remind me never to wear a 'seamless horizon' T-shirt on days I’m feeling rotund. 

If you look closely at the photos you can see the hidden LED headlights flanking the large, dark and low-set grille.

The rear of the new Sonata looks so different from the previous version, too, with its boot lid spoiler and LED tail-lights. 

The menacing body kit comes with the N Line grade and accentuates the sporty nature of this car. It’s a good thing it has an engine to back up the looks, but more on that later.

Inside, the Sonata has been given the new 12.3-inch curved screens and a digital climate control display, while the steering wheel is new and adorned with the Hyundai 'Morse Code' badge (the letter H is four dots in Morse Code). It’s a premium and modern looking cockpit topped off with suede and leather leather N Line sports seats.

I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.

It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.

Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.

And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.

The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.

The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.

Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.

Sedans might be sleek and sophisticated but practicality is not typically their strength because their low height means passenger access isn’t as easy as it is with an SUV, but mainly because the cargo carrying ability is limited by the relatively small boot opening.

Still, the Sonata N Line does have a big 480-litre boot and cabin storage has been improved thanks to the gear shifter being relocated to the steering column and freeing up space in the centre console for stowing items and a wireless phone charger.

Rear legroom is also good. I’m 189cm tall and I can sit behind my driving position with space to spare. Headroom back there is also good thanks to contoured heading which has a ‘carved out’ section for extra space.

Along with the wireless phone charger there are two Type-C USB ports up front and another two for the second row.

There are four cupholders (two up front and two in the second row) and decent sized bottle holders in the doors.

This lack of practicality compared to an SUV or even a station wagon means the Sonata N Line really isn’t the perfect family car.

The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.

That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.

There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin. 

The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.

There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.

The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.

Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.

There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990

The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.

Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.

There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.

There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.

Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.

Honestly, it’s a lot of stuff, and a lot of tech.

The Sonata N Line comes with a 2.5-litre turbo-petrol four-cylinder engine making 213kW and 422Nm, which is plenty of oomph, and it all goes to the front wheels through an eight-speed dual-clutch automatic transmission.

So no, there’s not a diesel version nor an all-wheel drive version, but this sporty engine suits the Sonata N Line perfectly.

That said a hybrid variant would be good seeing it’s 2023.

This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.

As we were saying above there’s no hybrid variant of the Sonata N Line and there should be. Actually there is, but Hyundai says it isn't available for the Australian market.

So, this turbo-petrol four-cylinder is all we have and according to Hyundai it uses 8.1L/100km on the combined cycle.

When we tested it at the launch our trip computer was reporting exactly 8.1L/100km, but the roads were clear, the traffic was nowhere to be seen, so you can expect that consumption to climb higher if you’re commuting around the city.

Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.

Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.

The Sonata N Line’s performance matches its sporty looks. That turbo-petrol engine is responsive and provides great acceleration, the transmission shifts fast and the steering is nicely weighted and accurate. 

Add to this better rigidity in the car’s structure in this updated model and a feeling of stability thanks to this being a sedan with a low centre of mass and you have a dynamic and enjoyable vehicle in your hands.

Sure it doesn't have the sky-high visibility that comes from the pilot’s seat of an SUV, but the Sonata N Line is for those who like to drive but still want the practicality of four doors, back seats and a boot.

First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.

But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.

MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.

Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.

The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.

There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.

As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.

The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.

The Sonata N Line is covered by Hyundai’s five-year, unlimited-kilometre warranty. 

Servicing is recommended annually or every 10,000km. There’s no capped price serving but you can buy a 'Lifetime' or a five-year plan that work out to be between $350-$400 on average a year. 

The IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.
