Hyundai Ioniq vs Mercedes-Benz A-Class

What's the difference?

Just like the Kona EV, Hyundai's Ioniq is still one of the best EV options on the market today. It strikes an excellent balance by offering significantly more range and better energy consumption than the more affordable Nissan Leaf or MG ZS EV, while providing the familiarity of the Hyundai spec and drive experience at a price only a little higher than a top-spec Prius.

Its relatively high score is a product of these factors, but also the way in which its interactivity offers the early adopters the engagement they will be searching for.

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

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

The Ioniq follows in the footsteps of eco hatches before it. You'll note this car's similarity in profile to the Toyota Prius, both shaped as such to secure low drag figures and therefore better economy and longer range.

While the Ioniq is a little more sedate than the wacky angles of the current Prius, there's no getting around the fact it's not exactly a cool shape. You could say it's interesting, perhaps, in the way it warps the low-drag box to Hyundai's styling cues, but dorky nonetheless. The LED headlights help lift it  a little, but the filled-in grille and small 16-inch wheels hardly lend this car extra street cred.

The Ioniq is more a proof of concept for early adopters who care a little less about the way the car looks and a little more about its drivetrain and technology, which is clearly the  focus here.

This can be seen in the Ioniq's interior, which has been re-worked for its most recent update. The digital features are impressive, with the floating 10.25-inch screen now totally dominating its dashboard.

I also like how the brand has given the instrument cluster a more modern design, with a cool floating bridge element over the top to eliminate glare, and, as always, Hyundai has made ergonomic use of its excellent switchgear and tidy steering wheel from the i30 and Kona ranges.

The climate unit has lost its tactile dials, replaced by touch-panel controls, and the lack of a transmission under the centre console has allowed plenty of negative space for the brand to play with, in this case a huge storage bay. There are also elements from more recently launched Hyundai models, which help to tidy the centre space up further, like an upright wireless-charging bay and shift-by-wire drive selector, which all looks very modern and neat.

It's a step towards things to come from the newly minted Ioniq sub-brand, which will do a lot more of this stripped-back, space-saving stuff with its next vehicle, the Ioniq 5 SUV. For now, though, the Ioniq is good as a half-step into the future. It's not as outlandish as a Tesla Model 3, for example, and will better suit a buyer looking for something a bit more familiar that still has a futuristic edge.

Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

As mentioned, there's actually quite a lot of space in the Ioniq cabin, and the design has been further stripped back with its most recent updates.

The front seat seems a bit high for a hatch, although ergonomically everything is correct for the driver, with a good amount of adjustability in the seat back and wheel.

The big, bright multimedia touchscreen is easy to use, and the single centrally mounted volume dial is welcome, but I do sorely miss the dials  for adjusting fan speed and temperature. Touch-panel controls, to me at least, are always inferior.

As already mentioned, the centre-console area under the climate unit has been almost entirely deleted for the electric variant, granting the driver a little more knee room, and leaving a deep rubberised bay for loose objects, maybe even small bags. This area also houses two 12v power outlets and one USB port. The centre console has been re-worked to include a smart, space-saving upright wireless-charging bay for your phone, the shift-by-wire console, and controls for the heated and ventilated seats. This area also hosts two large bottle holders, and a large centre-console box.

As is usual with Hyundai models, there's also a large bottle holder in the door, alongside a practical bin.

Rear passengers are treated to decent legroom, about on par with what you'd expect in a hatchback. Headroom is a little limited, both for getting in and out, with the descending roofline, so if you have family or friends taller than my 182cm height, they might be less than pleased.

The rear-seat area gets bottle holders in the doors and in the drop-down armrest, although there are no power outlets, just dual adjustable air vents.

The hatch body of the Ioniq makes for a decent boot volume of 357 litres, enough for a large pram or, in the case of my testing, the largest of the CarsGuide luggage cases, with ease. Hyundai gives you a little satchel to tidily store the standard powerpoint to Type 2 charging cable. A Type 2 to Type 2 cable, which you will need to charge at public outlets (up to 7.2kW) is not included.

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

We’ll get to the major change under the bonnet shortly, but another significant alteration for this latest C 43 is the price.

It now starts at $134,900 (plus on-road costs), which pushes it well above its market rivals, the BMW M340i xDrive and Audi S4, which start at $104,900 and $106,200, respectively.

However, Mercedes has added more technology under the bonnet and loaded the C 43 up with standard equipment, including its '4Matic' all-wheel drive system, adaptive damping, rear-wheel steering and 20-inch alloy wheels.

In terms of creature comforts, the C 43 is well-appointed, with leather upholstery, a head-up display, augmented reality navigation, a panoramic sliding sunroof, and a Burmester 3D surround sound system.

There are two option packages for the C 43. The 'Digital Light Package' costs $2400 and adds Multibeam LED headlights with 'Ultra Range' highbeam, 'Adaptive Highbeam Assist Plus' as well as active light function and cornering light function.

The 'Performance Ergonomics Package' includes AMG Performance front seats, an AMG Performance steering wheel in Nappa leather and microfibre and the 'AMG Track Pace' system for an additional $5200.

The Ioniq electric has a single motor on the front axle producing 100kW/295Nm. It's the least powerful EV in Hyundai's range, but still out-punches cars like the Toyota Prius on raw power. It drives the front wheels via a single reduction-gear transmission, and the Ioniq electric also has re-worked regenerative braking for its most recent update.

This is powered by a huge-for-its-size 38.3kWh lithium-ion battery pack under the floor.

The biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

The huge 38.3kWh battery pack and official combined energy consumption of 15.7kWh/100km, grants the Ioniq electric an impressive 311km (WLTP) range. As already mentioned in the pricing section, this lets the Hyundai electric hatch strike a good balance for urban commuters, however, under our mostly urban testing, it's an even better story.

For context, electric cars are far more efficient when operating in an urban scenario than they are on the open road. This is because they can regenerate energy more often and are less susceptible to losses from drag. The Ioniq has a superb regenerative-braking system, which can be completely customised to the user's preference. Want to drive it with no regen braking (like a normal car)? You can. Want to have the full eco experience, and have the car's motor bring it to a halt even without using the brake pedal, thereby maximising the amount of energy recouped? You can absolutely do that, too.

For most of my week, I stuck the Ioniq in its maximum regenerative setting and was very impressed to find it return an efficiency rating of 12.3kWh/100km. Not only is this number well below its claim, it's by far the most efficient electric car I have driven, and the only one I haven't tried yet is the brand-new MG ZS EV.

Colour me very impressed. The Ioniq charges via the most popular socket, the European Mennekes Type 2 combo. On DC, the Ioniq can charge as fast as 100kW allowing for a charge time of 54 minutes from empty to 80 per cent. On AC, its max charge input is a frustratingly low 7.2kW, making for a charge time of six hours and five minutes (more expensive rivals will charge at 11kW or even the max 22kW),  while from a 240v wall outlet (~2.3kW) it will charge in 17 hours and 30 minutes.

My single charge session was at a council-supported clean-energy Tritium charger with a max output on DC of 112kW. It charged my Ioniq from about 35 to 80 per cent in 32 minutes, and cost around $7.

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

The Ioniq's familiar Hyundai switchgear makes it largely feel like the brand's i30 from behind the wheel, and this is a very good thing. This car is immediately ergonomic and user friendly, although the seating position is a little high, preventing it from feeling particularly sporty.

The Ioniq emits a pleasant choral tone at low speeds, which enhances the perception you're steering something from the near future. It also helps alert pedestrians nearby, which was one of my pet peeves about the silent Tesla Model 3. The noise is interesting enough that you'll have people peering closely at it to figure out what's going on. It even gets louder as you accelerate, as though the motor is making it and it's not entirely artificial. Cool.

This EV is silky smooth to drive and accelerate. Like other Hyundai electric cars, it doesn't have the unleashed electric torque of a Tesla, but it feels  well attuned to driving around in an urban scenario, with viscous acceleration and regenerative braking. I was surprised to discover how heavy it feels, though.

I was expecting it to be heavier than its hybrid or PHEV counterparts but compared to the hybrid Prius I drove only a week or two prior, the electric Ioniq feels obese.

Upon closer examination, the Ioniq electric weighs 200kg more than the Prius, at 1575kg. It doesn't sound outrageous but it's enough to have this little car's suspension wallowing and occasionally crashing over bumps that wouldn't bother its hybrid versions or, indeed, the Prius.

This is perhaps emblematic of the issues facing smaller EVs like this. To get more than 300 kilometres of range, they need a lot of heavy batteries. Manufacturers can better hide this with the existing heft and better suspension travel of SUVs. The Kona EV, for example, feels less hefty than this little hatch.

Regardless, the electric motor dispatches with the Ioniq's weight easily when you really want to accelerate, and while it doesn't provide the hold-on-for-dear-life acceleration of Teslas, it's more than enough for a daily commuter. Unlike the Prius, the Ioniq does genuinely feel pretty sporty in the corners, thanks to steering that's on the heavier side, and a firm, responsive damper tune.

The regenerative braking is particularly good on the Ioniq. Using paddle-shifters usually reserved for changing gears, the Ioniq instead lets you  alter the amount of regenerative braking available. Feel like coasting a bit faster? Flick the Regen braking off. Feel like maximising economy and range? Max it out in the drive mode of your choosing, and you can use it as essentially a ‘single pedal' car (you can go or stop by using the throttle alone).

It even has an auto mode, which I found to be pretty intuitive. Paired with a few different display options to let you get superior feedback on how you're tracking with battery usage, it's brilliant, and more electric vehicles should take note.

So, this is an eco-focused electric car that is reasonably engaging to drive if a little heavy. Most importantly for the electric era, it's highly interactive, helping you really understand how your inputs are affecting its battery usage, and how you can better drive it to maximise range.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

The C43 gets a comprehensive list of safety equipment that leaves little out. Obviously there are the usual passive safety items, like 10 airbags, including dual-front combined pelvic/thorax airbags and a front centre bag that drops between the front seat passengers to minimise the chances of a head clash.

Also included as standard is autonomous emergency braking front and rear (covering speeds between 7.0-200km/h), adaptive cruise control with active stop/go, a 360-degree parking camera, 'Active Parking Assist', 'Active Lane Keeping Assist', 'Blind Spot Assist' and, of course, anti-lock brakes with 'Brake Assist' and 'Adaptive Brakes' with Hold function and electronic stability control.

Also included are dusk-sensing LED lights, rain-sensing wipers and run-flat tyres with tyre pressure warning.

The C43 also comes equipped with Mercedes’ 'Driving Assistance Package Plus', which adds even more safety gear. This includes 'Active Blind Spot Assist', 'Active Brake Assist with Cross-Traffic Function', 'Active Emergency Stop Assist', 'Active Lane Change Assist', 'Active Lane Keeping Assist', 'Active Steering Assist', and 'Active Stop-and-Go Assist'.

While the C43 hasn’t been specifically crash-tested, the latest C-Class was rated by ANCAP with a five-star score for all models except the upcoming C 63 S E Performance.

Hyundais are all covered by a competitive five-year and unlimited-kilometre warranty, which includes 12 months of roadside assist. The roadside assist is topped up for an additional 12 months with every genuine service, and the battery pack in EV models like the Ioniq is covered for eight years or 160,000km.

Hyundai's service pricing is amongst the best in the business, and with less moving parts, the electric Ioniq is the cheapest in the range with the first five services for the life of the warranty fixed at just $160 per 12 monthly or 15,000km interval.

The C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.
