Hyundai Elexio vs Mercedes-AMG E63

What's the difference?

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 E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.

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.

The E 63 S has been massaged for 2021 starting with flatter headlights, AMG's now signature 'Panamericana' grille, and a high gloss black flap across the top of the curved 'Jet Wing' section defining the lower part of the nose.

At the same time, the vents on either end of it are larger and feature twin transverse louvers to guide cooling air to wherever it's needed.

It's all about what AMG calls 'optimised aerobalance' but the form is just as appealing as the function. The characteristic 'Power Domes' in the bonnet dial up the muscle, as do the fat wheel arches (+27mm each side), and 20-inch rims with distinctive aero inserts.

This car's optional exterior carbon package consists of a front splitter, side sills, a flash near the fender badges, the exterior mirror covers, the boot lid lip spoiler, as well as the lower apron around the redesigned diffuser and quad tailpipes.

New, intricately styled LED tail-lights are also flatter, but there's even more going on inside.

A new AMG sports steering wheel features three rounded twin-spokes with new switches on the bottom to control the car's dynamic set-up.

It also picks up a new take on the small touch-sensitive controllers used to adjust the instrumentation and manage other functions like phone calls, audio and the cruise control.

Not sure I'm in love with them at this stage. In fact, the words fiddly, imprecise, and frustrating come to mind.

Nappa leather covering the superb AMG sports seats, upper dash, and door beltlines remains standard, but the show-stopper is the 'Widescreen Cockpit' - twin 12.25-inch digital screens for the MBUX multimedia interface on the left and instruments on the right.

The instrument cluster can be set to 'Modern Classic', 'Sport' and 'Supersport' displays, with specific AMG read-outs such as engine data, gear speed indicator, warm-up status, car set-up, as well as a G-meter and 'RaceTimer.'

To borrow an official automotive design term, it looks schmick. Overall, with touches like open-pore black ash wood trim, and brushed metal highlights, the interior looks efficient but classy, with an obvious attention to detail in the layout and its execution.

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.

At just under 5.0m end-to-end the E-Class sits in the upper range of the mid-size luxury spectrum. And almost 3.0m of that is accounted for by the distance between the axles, so there's plenty of space inside.

The driver and front passenger are provided with heaps of room to breathe, and there's a surprising amount of space for those in the back as well.

Sitting behind the driver's seat set for my 183cm (6'0”) position I had more than adequate head and legroom. But access to and from the back is a struggle for full-size adults.

The rear doors open out a long way, but the limiting factor is the size of the aperture, necessitating excessive contortion of the head and limbs to fold in and out of the car.

Connectivity runs to two (power-only) USB-C sockets in the front centre storage bin, as well as another USB-C (for power and multimedia) and 12-volt power outlet in the centre console.

Speaking of the front centre storage bin, it's a decent size and has a padded split lid so it can double as an armrest. There are two cupholders in the front console, a generous glove box, as well as long door compartments with recesses for large bottles provided.

There's a pair of USB-Cs along with another 12-volt socket in the back, sitting under the climate control panel with adjustable vents in the rear of the front centre console. Nice.

The fold down centre armrest incorporates a lidded (and lined) storage box as well as two pop-out cupholders. Again, there are bins in the doors with room for smaller bottles.

The boot offers 540 litres (VDA) of volume, and is able to swallow our three-piece hard suitcase set (124L, 95L, 36L) with room to spare, or the substantial CarsGuide pram, or the largest suitcase and pram combined! There are tie-down hooks to help secure loads, too.

Don't bother looking for a spare of any description, a repair/inflator kit is your only option. And the E 63 S is a no-tow zone.

So, first of all, let's get the price out of the way. At $253,900, before on-road costs, this car's competitive set is a bruising, all-German trio comprising the Audi RS 7 Sportback ($224,000), BMW M5 Competition ($244,900), and Porsche Panamera GTS ($309,500).

And no surprise, it's loaded with all the luxury features you'd expect in this part of the market. Here are the highlights.

On top of the standard performance tech and safety equipment fitted to the E 63 S (covered later in this review), you'll also find: Nappa leather trim (seats, upper dash, upper door cards, and steering wheel), MBUX multimedia (with touchscreen, touchpad, and 'Hey Mercedes' voice control), 20-inch alloys, three-zone climate-control, interior ambient lighting, auto LED headlights (with 'Active High Beam Assist Plus'), eight “energising comfort programs” (with 'Energising Coach'), an 'Active Multicontour' front seat package, the 'Air Balance' package (including ionisation), and keyless entry and start.

Also included are the the 'Widescreen' digital cockpit (twin 12.25-inch digital screens), 13-speaker Burmester audio with digital radio, Apple CarPlay and Android Auto, a panoramic sunroof, adaptive cruise control, a head-up display, augmented reality satellite navigation, 'Parktronic' self-parking, electric front seats, seat cooling and heating front (heated rear), heated front centre armrest, a power-adjustable steering column, auto rain-sensing wipers, a wireless device charger, illuminated door sills, as well Amazon Alexa, etc, etc, etc.

And our test car also featured a couple of tasty options. An exterior carbon package ($7500), and AMG's professional grade ceramic composite brakes ($15,900), for an as-tested price of $277,300.

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 E 63 S is powered by the M178 version of the all-alloy 4.0-litre twin-turbo V8 engine used across numerous AMG models from the C-Class up.

Thanks in no small part to direct injection and a pair of twin-scroll turbos (located in the engine's 'hot vee' to optimise throttle response), this all-alloy unit produces 450kW (that's 612hp) from 5750-6500rpm, and 850Nm from 2500-4500rpm.

And as per standard AMG practice for its Vee engines, this car's powerplant was built from scratch by a single engineer in Affalterbach. Thank you Robin Jäger.

AMG calls the nine-speed transmission used in the E 63 S an MCT, which stands for Multi-Clutch Technology. But it's not a dual-clutch, rather a normal auto transmission using a wet clutch as opposed to a conventional torque converter, to connect it to the engine on take-off.

Drive goes to all four wheels via Merc's '4Matic+' AWD system, built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the E 63 S emitting 280g/km of CO2 in the process.

That's a pretty hefty number, but in line with this car's proportions and performance potential.

And Merc-AMG has gone to great lengths to minimise fuel use. As well as the standard 'Eco' stop-start function, in the 'Comfort' drive program cylinder deactivation becomes active, the system able to drop four cylinders anywhere between 1000 to 3250rpm.

There's no physical hint of half the cylinders leaving the party. The only clue is a blue icon on the dash indicating a temporary shift to V4 operation.

Despite all that effort, however, we saw a dash-indicated 17.9L/100km over a mix of urban trundling, highway cruising, and some spirited dynamic assessment.

Recommended fuel is 98 RON premium unleaded (although it'll run on 95 at a pinch), and you'll need 80 litres of it to fill the tank. That capacity translates to a range of 650km according to the factory claim, and 447km using our real world result.

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.

AMG's major goal with this upgrade of the E 63 S was to maintain its dynamic response and ferocious performance, but dial in the extra comfort customers had said they wanted.

So, the 4Matic+ AWD system has been fine-tuned for more smoothness as has the Comfort option in the dynamic set-up. But we'll investigate that shortly.

First, that 4.0-litre turbo V8 in the nose is claimed to slingshot this roughly 2.0-tonne sedan from 0-100km/h in just 3.4 seconds, and it feels every bit that fast.

With 850Nm available from 2500-4500rpm and nine gear ratios to help keep you operating in that Goldilocks band, mid-range thrust is monumental. And thanks to the bi-modal sports exhaust it sounds beautifully brutal.

The nine-speed auto's wet clutch, as opposed to a conventional torque converter, is designed to save weight and optimise response. And while some will tell you an auto with one input shaft is never going to be as fast as a dual-clutch with two, shifts are rapid and direct. The wheel-mounted shift paddles are larger and set lower, as well.

The AMG 'Ride Control+' suspension with multi-chamber air suspension and adaptive damping is amazingly good. The underlying set-up is by multi-links front and rear, and despite riding on big 20-inch rims wrapped with low-profile, high-performance Pirelli P Zero rubber (265/35 fr - 295/30 rr) the Comfort setting is incredibly... comfortable.

Slip into 'Sport' or 'Sport+' and the car immediately feels tauter but far less compliant and forgiving. An impression reinforced by the engine, transmission, and steering shifting to a more buttoned-down mode at the same time.

The standard dynamic engine mounts play a big part here. Able to make a soft connection for maximum comfort, but switch to a rigid link when required.

But no matter which mode you're in, the car is well damped and feels beautifully balanced in quick cornering. And the E 63 S's electro-mechanically-assisted variable-rate steering is progressive, feelsome, and accurate.

The 4Matic+ AWD system is built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

Torque distribution happens imperceptibly, the big V8 putting its power down emphatically, with various electronic systems tieing up the loose ends as you aim up for the next corner.

 There's even a 100 per cent RWD Drift mode available in the Race setting, but without a race circuit at our disposal this time around that'll have to wait for another time.

The optional ceramic brakes feature huge rotors and six-piston front calipers, and stopping power is immense. And the good news is they operate quickly but progressively at normal pottering around town speeds. No warming up required to get them in an optimal temperature zone (as can be the case with other ceramic set-ups).

The three-pointed star's white-coated boffins have gone to town on the E 63 S, and the car is as good as it currently gets in terms of active and passive safety technology.

You could argue this car's dynamic ability is its strongest contributor to crash-avoidance. But a broad suite of features, specifically designed to keep you out of trouble includes, forward and reverse AEB (with pedestrian, cyclist, and cross-traffic detection), traffic sign recognition, 'Attention Assist', 'Active Blind Spot Assist', 'Active Distance Assist', 'Active High Beam Assist Plus', 'Active Lane Change Assist', 'Active Lane Keeping Assist', and 'Evasive Steering Assist.' That's a lot of assists.

There's also a tyre pressure monitoring and pressure loss warning system, as well as a brake priming function (monitors release speed on the accelerator pedal, moving pads factionally closer to the discs when required), and brake drying (when the windscreen wipers are active the system periodically applies just enough brake pressure to wipe water off the brake rotors to optimise wet weather efficiency).

But if an impact is unavoidable the 'Pre-Safe Plus' system is able to recognise an imminent rear-end collision and fire up the rear hazard lights (at high frequency) to warn following traffic. It will also firmly apply the brakes once the vehicle is stationary to minimise the risk of whiplash injuries if the car's then hit from behind.

If the potential crash is coming from the side, 'Pre-Safe Impulse' inflates air chambers in the side bolsters of the front seat backrest (within a fraction of a second) moving the occupant to the side towards the centre of the car, away from the impact area. Amazing.

As well as that, there's an active bonnet to minimise pedestrian injuries, an auto emergency call function, 'Crash Response Emergency Lighting', even a first aid kit and hi-vis vests for all occupants.

For the record, the current E-Class received a maximum five-star ANCAP assessment in 2016.

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.

All AMG models sold in Australia are covered by Mercedes-Benz's five year/unlimited km warranty, with 24-hour roadside and accident assistance included for the duration.

Recommended service interval is 12 months or 20,000km, with pricing for a three-year (pre-paid) plan set at $4300, a $950 saving overall relative to its three year, pay-as-you-go 'Service Solutions' capped price program.

And if you're happy to fork over a little more up-front, there's a four-year service deal at $6300, and five years coming in at $7050.
