Audi S5 vs MG Im6

What's the difference?

The Audi A5 remains a convincing option in the premium mid-size sedan category, even with the near-$10K price increase over its equivalent grade A4 predecessor.

Even in its base spec, it’s a lovely thing to drive and adds enough new kit to be a reasonable option when it comes to value. In terms of tech usability, it stands out from rivals. Practicality is still king for Audi.

But for the heart-over-head types, the S5 is fast and fun while remaining a comfortable cruiser and the price is decent. On a personal note, a six-cylinder wagon? That's a big yes from me.

For the time it’s available, it’s hard to go past the value on offer in the S5 Edition One. Getting an AWD V6 with that kind of capability for under $100K is something that's sure to tempt buyers. If it doesn’t, we need to take a good look at ourselves.

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.

The A5 incorporates Audi’s new design language in a way that makes the 2026 model stand out from Audi’s older offerings, but we won’t know how well it works in the family until more new-gen Audi cars arrive.

For now, the A5 is a generally handsome car. It very much looks like an Audi from the front, even a recent A4 if you only very quickly glanced.

The aforementioned S line styling does plenty in making even the base Audi A5 look like a properly luxe thing. There were a few double-checks at the launch to make sure drivers were getting into the right cars.

Fortunately the new car’s designers refrained from busying up the car with trim, the only big features being the side vents at the front.

But even in Avant form the S5 looks athletic, quad-exhausts in the lower bar and the angular rear bodywork moving away from the previously softer, more rounded look Audi had gone with before.

Inside, the changes are arguably more obvious. The A5 is now much more ‘screeny’ than before, especially if optioned with the passenger-side touchscreen.

It’s still decidedly Audi in its layout and design, with geometric shapes on the steering wheel, screen housing, door cards and even on the gear shifter, which is no longer the more traditional handle-type.

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.

…and that gear selector is a bit indicative of the new A5’s interior. It’s now more of a switch that requires a little more attention than the traditional shifter, just like the way the more screen-focused interior requires a little more of your eyeball time than physical buttons.

Don’t get me wrong, as far as screens in modern cars go, Audi seems to have made it as easy as possible to use the new-gen software in the A5. The menus are clear, there are good shortcuts and there’s no lag… but buttons are always better when your focus needs to be on the road.

Fortunately the driver display is nice and clear, it’s a good update on Audi’s ‘Virtual Cockpit’ and you can set it to display important information without looking too busy.

Ergonomically, the way the central screen is angled towards the driver, the centre console layout and the small control panel on the door for lights, mirrors and the like all seem to be well considered and mean you don’t have to awkwardly reach for anything.

There are a few quirks specific to the A5 and S5, one being that if you opt for the panoramic sunroof, it comes with a transparency switch rather than a physical cover, so it doesn’t do much to keep the light out.

It’s also good to note that the passenger screen - again, if optioned - turns to privacy mode when playing media so as to not distract the driver. Pretty handy!

Behind the front row, a regular-sized adult should have enough room to sit comfortably for a decent amount of time without feeling cramped. The light through the sunroof comes in handy here.

Behind that is a 445L boot in Sedan form, or 1299L with the rear seats folded down. As an Avant, the space increases to 448L and 1396L respectively.

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 Audi A5 is powered by a four-cylinder turbo-petrol engine which powers the front wheels via a seven-speed dual-clutch automatic transmission. It makes 150kW of power and 340Nm of torque, and should, Audi says, propel the A5 to 100km/h in 7.8 seconds before (eventually) reaching a top speed of 248km/h.

The S5, in all its variants, is powered by a 3.0-litre turbo-petrol V6 which is assisted by a mild hybrid system. It produces 270kW and 550Nm, sending that to all four wheels via a similar seven-speed dual-clutch.

The S5 is much quicker as a result - 100km/h comes along in just 4.5 seconds according to Audi, before reaching a 250km/h top speed.

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.

Audi claims the A5 uses 6.9 litres of fuel per 100km, which should theoretically deplete the 56-litre fuel tank after 811km of driving. We couldn’t test this on the launch, but reaching claimed fuel efficiency figures remains an elusive challenge.

The S5, according to Audi, comes with an impressive 7.1L/100km figure in Sedan form, or 7.2L/100km as an Avant. That’s 788km and 777km of theoretical driving range if you’re up for a challenge.

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.

One of the first press cars I ever drove as an even younger lad than I am now was the circa-2017 Audi S4.

Without the perspective of all the many, many cars I've since driven, that S4 blew my mind a little bit with its combination of capability and refinement.

Now, with the context of most of the cars available to the Australian buyer in mind, it’s reassuring to get into this new generation and find that the mid-size Audi torch has been gracefully passed on.

Audi says the new generation, sitting on its new platform, has more focus on balanced driving dynamics, steering precision and steering feel. Without sacrificing comfort, Audi wants the A5 to be a sharper driver’s car.

It might not gel with the Euro tradition of a rear-drive executive sedan given the base A5 is front-wheel drive - the brand of course focusing on its quattro all-wheel drive system - but the A5 is decidedly agile for its size. 

Compared to the S5 especially, as the A5’S 1770kg plays the S5’s 2025kg in Sedan form (2040kg as an Avant). It’s a noticeable weight difference, and it makes the A5 more playful without getting properly ragged.

It also rides on smaller 19-inch wheels and would overall probably make for the better daily driver. Even without the all-wheel-drive traction and extra power the S5 offers, the A5 makes a good case for properly plush commuting. Its 150kW isn’t lacking by any means, and that 340Nm does plenty to help when overtaking.

Its suspension feels well damped, keeping the road’s imperfections out of the cabin without numbing the ride and leaving you without feedback. The steering is similarly direct without being too heavy, making the A5 feel athletic for its size.

But for all the A5’s strengths, there is something undeniable about a six-cylinder European sedan (or wagon). The S5 is heavier, sure, and therefore not as naturally nimble, but it makes up for it. And it’s not just the extra power and mild-hybrid assistance.

It’s a great highway cruiser for a start, but it also adds the confidence of all-wheel drive to a trip, which proved extremely useful on the very rainy winter day we tested it. It holds up well on rough surfaces despite the bigger wheels and extra heft, plus it doesn’t feel out of hand when cornering fast, rolling into a predictable understeer rather than quickly losing traction.

But if you’re in any way conscious of your budget, consider the Edition One. It doesn’t lack any of the key things that make the S5 great, and you get to pocket enough money to buy a second used car.

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.

Audi’s five-year/unlimited kilometre warranty is starting to fall behind the industry standard, though is about normal for a premium brand. On top of this, customers can opt to purchase extra years of warranty up to a maximum nine years which costs $3590.

Audi does also offer 12 years of bodywork manufacturing warranty against corrosion or perforation. There’s also five years of Audi roadside assistance.

Servicing intervals for the A5 come in at every 15,000km or 12 months, with customers able to purchase fixed-price servicing plans at a discount compared to paying per service.

A five-year servicing pack for the A5 Sedan is $3360, and for the S5 it’s priced at $3540.

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.
