Mercedes-Benz S560 vs Hyundai Elexio

What's the difference?

Both of these vast vehicles are phenomenally comfortable - this is the kind of car that Mercedes does so well, and has done for decades. The S Class is rarely a disappointment but it's difficult to believe that such a big, heavy GT car can also dance the way the S63 does.

The S560 is far more weighted to being a GT - supremely comfortable with that active suspension, a growly, refined V8 and a cabin full of gadgets and comfort. The S63 is altogether more aggressive, to look at and to drive. Lopping the roof off both of them adds weight but, like any cruiser, also puts you out in the sun, the breeze and into your surroundings. Plus, in the case of the S63, you get more exhaust noise.

They're two very different cars and not just because of the engine. After all these years admiring it from afar, the S63 has delivered on my teenage expectations - fast, smooth and utterly mad.

The Elexio doesn't really push any boundaries in terms of its exterior design, its powertrain, or its battery. It doesn't drive itself. It doesn't look like a spaceship. And apart from some interior quirks, it's all pretty familiar in the way it goes about its business.

And I think maybe that's the point. Maybe that's what people are really looking for. Because Hyundai says this will be its best-selling EV in the country. And on our short test, we can't find too many reasons to disagree.

The S Class Coupe is obviously related to the sedan but manages a svelte appearance. Slimmer hipped and with a more Coke-bottle shape, the Coupe - if you squint a bit - has a bit of the classic old pagoda about it. Obviously you can't do pillars that slim anymore, but the glass roof takes away some of the visual weight inside and out. 

The cabriolet's roof is nicely integrated and looks good when it's  up, which isn't always the case.

They all look long, though. It's obvious to see why the cars all run on 20-inch wheels - anything smaller would look hilarious.

The cabin is a fairly sensible re-imagining of the E-Class. The big twin-screen layout of the dash and multimedia system seems a bit more at home here. The chintzy Burmester speakers in the doors let down an otherwise classy cabin, which steers clear of otiose vulgarity in looks and materials.

I don't want to sound boring, but the thing I really like about the Elexio exterior package is there's nothing too challenging about it. Some of the Hyundai Ioniq cars can be a bit more polarising (and, in the case of the Ioniq 6, a lot more polarising) but there's none of that going on here.

It feels very clean, fairly timeless and like it's going to age pretty well. In short, it looks like a familiar family SUV with only really the full-width light bar, the cubed headlights and a bit of an architectural flourish at the rear three-quarter – which actually reminds me a bit of the Kia EV5 – giving it a more modern edge.

The wheels are 20 inches, there are only a handful of fairly predictable colours and it all just feels really familiar. But, as I mentioned, things do get a bit more out-there in the cabin.

Let's start with the good. I really like the fit and finish. It all feels very high quality and the materials used are lovely, including the velvet-like fabric in the door panels. I also like the square-edged steering wheel.

But the not so good? Now, the central screen looks great, but it controls everything – and I do mean everything. Apart from the steering-wheel controls, I couldn't locate a single physical button in the cabin.

Well look, if you end up in the back of the S Coupe, it's not a riot of space. Obviously it has back seats (the SL doesn't even squeeze a jump seat into its considerable length) but they're for occasional, if luxurious, use.

The boot is a reasonably decent 400 litres, obviously the cabriolet loses a few litres with the roof folded. Front and rear passengers will both enjoy a pair of cupholders and the whopping long doors will each hold a bottle.

At just over 4.6m long, just under 1.9m wide, and just under 1.7m tall, the Elexio fits snuggly between the smaller Kona Electric and Bigger Ioniq 5 among Hyundai's electric family. In family vehicle terms, it's marginally shorter than the brand's petrol and hybrid-powered Tucson.

But owing to the magic of EVs and their flat floors, the Elexio feels massively spacious in the backseat. I'm 175cm, and had no trouble getting comfortable behind my own driving position, with plenty of leg and headroom. 

Tech is pretty strong, too. There are twin wireless charging pads up front, a total five USB-C ports, and a household style plug (which car companies call Vehicle to Load) located in the boot.

There's storage in the doors and centre console, including a storage drawer, and cupholders up front and in the pulldown divider that deploys over the middle seat in the back.

But the weirdest thing is the driver screen, which is the only straight-ahead access the driver has to things like speed or navigation directions. It's a very cool 3D-effect display, but it utterly disappears if you're wearing polarised sunglasses. 

That's actually pretty common with all head-up displays, but they usually are projected above a traditional driver's binnacle. In the Elexio, it's the disappearing screen or nothing.

To be fair, the central screen also displays speed and crucial information, but I hate having to turn my head to look at it. It's my least-favourite thing about Teslas, and if you're wearing polarised sunglasses, the Elexio ends up feeling a lot like that.

I do love that there is an actual control to select Drive, Reverse or Park, and I adore the addition of a physical stop/start button, too.

There's also an auto-opening boot which reveals a 506-litre space with the rear seats in place, and 1540 litres with the 60/40 split rear seats folded flat. Keep in mind there's no spare tyre taking up space, though. You'll be leaning on the repair kit should you get a flat.

The Elexio arrives with just the one grade for now, the Elite, and the pricing is a bit weird. It lists at $61,990, but is actually being offered for significantly less than that at launch, with a special $59,990 drive-away deal in place until around the end of March.

There is a cheaper Elexio grade coming sometime in quarter two this year, and it will be $58,990. But I reckon you can expect a sharp drive-away deal there, too, at least at launch.

How does that stack up? I think we have to go on permanent pricing, rather than any special offers, and that puts the Elexio above its main rivals in the BYD Sealion 7 ($54,990 for the Premium), the Tesla Model Y ($58,900 for the Premium Rear-Wheel Drive) and the Xpeng G6 ($54,800 for the Standard Range). Though the cheaper Elexio variant will help to narrow that gap.

There are significantly cheaper electric SUVs that fall into the mid-size category, too. Like the Geely EX5 and Leapmotor C10, both of which are less than $50k on the road.

Anyway, for now the Elite arrives with 20-inch alloys, cube-style LED projector lights, an auto-opening boot and Hyundai’s Digital Key, which allows you and up to 14 other people to use their phone as the key.

Inside, there’s leather seating that’s powered for driver and passenger and heated and ventilated up front. There’s also dual-zone climate, twin wireless charging pads and a household-style power point to power your devices.

Where it gets really interesting, though, is with its cabin tech, which is seriously bleeding edge. The entire dash, from in front of the passenger to pretty much the edge of the steering wheel, is dominated by a 27-inch screen that actually gives the passenger more real estate than the driver.

It's impressive stuff, with high-res games for the passenger to play (including the super-sharp Space Invaders), but there's also wireless Apple CarPlay and Android Auto, twin wireless charging pads, and a relatively small head-up display (only located within the binnacle) for the driver.

All four coupes and cabriolets ship with Daimler's formidable 4.0-litre twin-turbo V8. The S560 scores 345kW/700Nm to drive the rear wheels through Benz's own nine-speed automatic. With all of that available, the S560 will crack the ton in 4.6 seconds and make a wonderful racket on the way.

Moving on to the S63, the same engine delivers a massive 450kW/900Nm. The run from 0-100km/h is dispatched in just 3.5 seconds and if I thought the S560 made a good noise, the S63 with its standard sports exhaust makes a better one. Again, Mercedes' nine-speeder is along for the ride.

There’s just the one powertrain on offer here — with a front-mounted electric motor, so front-wheel drive, that produces 160kW and 310Nm. That makes the Elexio feel spritely enough, but it’s no rocket ship.

The lower-powered 560 drinks 98RON at the rate of 8.5L/100km for the coupe and 9.9L/100km for the heavier cabriolet.

The S63 ups the ante with 9.9L/100km for the coupe and an identical 9.9L/100km for the cab.

Our launch program contained some...er...spirited driving, which would explain the mid to high-teens fuel figures.

Delivering the driving power is an 88.1kWh LFP battery, which Hyundai says equates to a WLTP driving range of 546kms.

The Elexio’s E-GMP platform is a 400-volt architecture, which does limit DC fast charging to around 120kW – the Ioniq 5, for example, will charge in excess of 230kW. 

Hyundai says you’ll go from 10 to 80 per cent in around 38 minutes plugged into our fastest chargers. AC home charging is capped at 10kW.

Let's start with the S560. That smooth V8 rumble is all you'll ever hear if you just slot into drive and go for a leisurely spin. The nine-speed automatic continues to be a revelation to me - in the GLC63 it's good and here, once again, it's excellent, finding the right gear for the occasion and riding the fat torque curve. Other nine-speed autos are not very good at all.

The test route for the S560 played to the strengths of the car. It had some lovely winding roads, which brought the trick suspension into focus - the Magic Body Control with curve function is hilarious. While the active suspension works hard at all times to ensure the ride is smooth and drama free, the Curve mode (no, really) actually leans the car into corners.

Those of you who remember the video game Wipeout 2097 will be big fans of Curve mode. As you approach a corner, you turn the wheel and then the car leans into the bend. This isn't active damping reading the road, it's the outside suspension lifting the car and the inside lowering it, so the car feels like it's gliding, like a hovercar. It's wild but oddly calming. Mercedes reckons it's great for those who get car sick. As I didn't have my wife on hand to test this theory - she chucks at the first sign of a corner - I couldn't verify this claim. That will have to wait.

The S63 AMG is a completely different proposition. The air suspension is more than up to the job of helping smother the effects of the car's considerable weight, meaning that no matter what you're up to, the car feels reasonably light on its feet. It never feels small, though, commanding the respect of the driver and plenty of space from other road users.

And boy, do you need some space if you kick the S63 into Sport mode. In true AMG style, the electronic reins relax and the big luxury coupe cheerfully kicks off. The tail will wriggle under an unsympathetic right foot, that signature V8 roar, crackle and hiss filling your ears. The S63 is always the harder-feeling car, but it delivers with a more sporting drive than the S560.

Being the generous soul I am, I volunteered to return the S63 to its home for the evening rather than consign it to the back of a truck. On the back roads I took to reach the highway, it was rock solid - fast, predictable and a lot of fun. Once I found the boring straight bits, it turned into a supremely comfortable cruiser, ticking along in ninth at the legal limit (and being Melbourne, it was very much the legal limit), dispatching overtaking with barely a flex of a toe. 

The active cruise took the stress of keeping away from the State Revenue Office's clutches while being quiet and utterly pleasant.

Ok, let's skip to the good part quickly. I really like the way the Elexio drives. Honestly, Hyundai (and, to be fair, Kia, Porsche, Polestar, Tesla, some German brands and Leapmotor with the new B10, amongst others I'm surely forgetting) are restoring my faith in how an EV can feel from behind the wheel.

It turns out they don't have to feel soft and saggy and come with a light sense of seasickness as standard. They can be engaging, connect you to the car and to the road below, and attack corners with some athleticism, too. 

And so it is with the Elexio, which – to be fair – has a spec sheet that reads a bit like a bedtime story, such is the lack of excitement in the numbers. A two-tonne-plus, front-wheel-drive family SUV that produces less power than a Toyota Camry doesn't exactly quicken the pulse.

And it's true that the flat-footed acceleration on offer won't knock your cap off (though it feels perfectly perky enough to get you up and moving). But the numbers don't tell the whole story here.

A sports car this ain't, but its driving nature perfectly suits the ethos of the car. The ride can feel a little harsh at times, but irons out most road imperfections to the point that you notice them, but they're not uncomfortable.

The steering is direct without being overly aggressive –though I prefer the sportiest setting with the heavier feel – and the body roll is minimal, too.

In fact, you can push the Elexio harder than you might think along twister roads, with plenty of confidence-inspiring stability and without too much complaint from the tyres. Because there's not a huge amount of power underfoot, and this is going to sound absolutely crazy, but it gave me (much-heavier) Mazda MX-5 vibes, in the sense that you can really feel like you're driving it without feeling like you're going to get yourself in too much trouble.

There’s a long list of safety stuff aboard the Elexio, including nine airbags and just about every active safety system you can imagine.

They seem better tuned than some of Hyundai's competitors too, without being too overzealous. That said, overspeed warnings remain an auto industry scourge.

Particularly clever is a system Hyundai calls 'Forward Collision-avoidance Assist 2', which shows just how far modern AEB (or autonomous emergency braking) systems have come. 

Once, and not so long ago, a vehicle could automatically apply the brakes if it sensed a collision ahead. Hyundai's system, though, not only works in both directions, but also detects pedestrians and cyclists as well as cars, and works when you're pulling out of a junction and it detects fast-moving oncoming traffic. It also detects traffic coming in either direction when you're travelling straight through an intersection, and when you're changing lanes.

The Hyundai Elexio wears a full five-star ANCAP safety rating, though one stamped 'tested in 2024'. The data was actually taken from the crash-test result of the related Kia EV5.

Mercedes offers a three-year/unlimited-kilometre warranty with roadside assist for the duration.

The company also offers both service plans (where you pay up-front as part of the vehicle purchase) and capped-price servicing on the coupes. Servicing over three years is in the order $2500.

The Elexio is covered by Hyundai’s new seven-year, unlimited-kilometre warranty, provided you service with Hyundai. If you don’t, then it's five years of coverage.

Service intervals are a pretty luxurious 24 months or 30,000kms, and Hyundai’s service plans will see you paying $779 at the two-year mark, and another $1118 at the four-year mark, which puts your annual cost at around $475.

I'd say that's about average, with the happily extended service intervals counterbalanced by slightly higher servicing costs than you might find with some competitors.
