Hyundai Ioniq 6 vs Mercedes-Benz CLA

What's the difference?

The Hyundai Ioniq 6 will stand out in any automotive crowd, thanks to its distinctive aero-influenced design.

It’s well-equipped for the money, surprisingly roomy, energy efficient and notwithstanding some niggles around the ride and steering feel, comes up to scratch dynamically.

Does it do enough to apply the thumb screws to the likes of Tesla's Model 3? I think it’s got a pretty good shot, and it will be interesting to see if EV buyers embrace the car’s unusual streamlined look.

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

Is the Mercedes-AMG CLA 35 the perfect choice in the sleek sedan’s line-up?

Well, if you are after outright performance, then the answer still clearly lies with the CLA 45. But for those that just want a little more pep compared to the standard CLA range, the 35 is undoubtedly the one to get.

It’s not without its flaws, though, commanding a $15,000 price premium over the CLA 250 and a tougher-than-we’d-like ride, but if you value a more engaging drive and a brisk 0-100km/h time, the CLA 35 should definitely be on your shopping list.

Lots of cars are said to be “shaped by the wind” but all you have to do is look at the Ioniq 6 to know that in this case it’s 100 per cent true.

In fact, images of the car in Hyundai’s wind tunnel show it performing more like a perfectly shaped wing than a four door sedan.

With a drag co-efficient (Cd) of 0.21 it’s slicker than the ultra low-drag Tesla Model 3 and Porsche Taycan. And while not conventionally pretty it’s certainly a striking and unusual design.

Flush door handles? Of course. Carefully sculpted spoilers front and rear? Yep. Active air flaps? Check. The RWD Dynamiq’s 18-inch alloy rims are shaped for aero efficiency, while the top-spec Epiq grade even swaps out conventional side mirrors for super-cool digital cameras and interior OLED screens.

And the sleek looks continue inside with a two-section dash divided horizontally by a swoopy winged insert and topped with a pair of 12.3-inch screens covering multimedia and instrumentation.

The look and feel is minimalist. A lot of the controls are on screen or digital, but a physical dial for audio volume gets a big safety and convenience tick. 

No gearshift in the bridge-like centre console. A rotary stalk is located behind the steering wheel on the right-hand side.

There’s configurable ambient mood lighting with six pre-selected themes and the materials used inside are suitably eco-friendly.

Cloth seat trim is recycled PET plastic, as is the headliner, the dashboard skin is manufactured using bio-ethanol, the carpet is made from recycled fishing nets (!), and bio paint (partially derived from vegetable oils) is used on the doors. 

Yes, there’s leather, but its dyeing process uses biodegradable flaxseed oil rather than conventional pigments, which is a good thing in terms of fewer harmful microorganisms in waste water, and is claimed to reduce CO2 emissions by 3.8kg per car. 

On the outside, recycled pigment paint made using ‘end-of-life’ tyres is applied to the body cladding, and bamboo charcoal pigment paint is used in the ‘Digital Green’ pearl colour option.

Speaking of which, there are seven other colours available; three more pearl shades - ‘Abyss Black’, ‘Ultimate Red’ and ‘Biophilic Ink’, as well a single metallic ‘Nocturn Gray’ and a solid ‘Byte Blue’. ‘Gravity Gold’ matt finish is the only extra-cost choice at $1000. 

From the front, the CLA 35 exterior oozes style and luxury.

Up front, the sleek and slender headlights emphasise the width of the fascia, while the large Mercedes logo sits proudly front and centre of the CLA’s nose.

There are subtle hints to the CLA 35’s sportiness too, with a slightly bulging bonnet and chiselled lower chin.

The grille is also unique on the 35, with a dual-horizontal slat design instead of the non-AMG CLA’s diamond pattern or the CLA 45’s Panamericana grille.

To my eye, the front of the CLA 35 is actually a bit too tame in styling for an AMG model. I prefer the in-your-face aggression of the CLA 45’s widened track and front grille, while the CLA 35 opts for more subtle styling cues. To each their own, though.

The silver paintwork of our test car probably doesn’t help, and if it was my choice I'd pick 'Sun Yellow' or 'Denim Blue' to stand out a bit more from the sea of black, grey and white German cars out there.

Move to the rear of the car though, and a large rear diffuser, big dual-exhaust outlets and a bootlid spoiler are much more befitting an AMG model.

Step inside the CLA and you will see it adopts the same dashboard design as all new-generation Mercedes vehicles built on the MFA2 platform, with the 'MBUX' dual-screen layout, large air-vents and central touchpad.

Our car was specced out with red-leather interior, which is a bit too loud for my tastes, but a two-tone black leather/titanium grey combo can also be had at no extra cost.

Sitting inside the CLA 35, you can tell it’s a modern car thanks to the clean layout of all the controls, while the screen-heavy dashboard definitely makes it feel tech-focused.

The Ioniq 6 is just under 4.9m long and the wheelbase is close to three metres, so no surprise there’s an impressive amount of space inside the car.

A flat floor enhances the roomy feel, plus controls for windows and mirrors are located in the centre console or on the dash rather than the front doors, which has allowed the armrests to be trimmed down for some extra breathing space.

As mentioned earlier, there’s no gearshift in the centre console, either. It takes the form of a rotary stalk on the right hand side of the steering column. It doesn’t take long to get used to and I found it pretty handy to use.

There are large bins in the doors with space for bottles, two cupholders in the console and a medium-sized lidded storage box (which doubles as a centre armrest) between the seats.

A lengthy tray underneath the main console keeps additional loose items under control and a generous glove box slides out from the dash rather than flipping open. So, there’s plenty of storage on offer.  

Move to the rear and it feels like you’ve teleported into the back of a stretch limo. With the driver’s seat set to my 183cm position there is huge legroom.

Hyundai says thanks to the use of high strength steel the backs of the front ‘relaxation’ seats fitted to the AWD models are appreciably thinner than normal, also increasing rear space.

Rear headroom is fine sitting in a normal, relaxed position, although sitting bolt upright my bonse grazes the headliner. 

Three abreast for adults will be okay for short runs, but not a goer for lengthy road trips. Three up to teenage kids will be fine, though.

Speaking of kids, parents will appreciate ‘Quiet Mode’ which limits audio to ‘25’ in front and mutes the rear. Perfect for uninterrupted sleep back there, or keeping the noise to a minimum for those furiously focused on their favourite game or a movie.

Backseaters are provided with bins in the doors, although the section scooped out for bottles is small, there are two cupholders in the fold-down centre armrest, netted map pockets on the front seat backs and a small slot for keys or a phone under the adjustable air vents at the rear of the front console.

Connectivity and power options run to three USB sockets in the front (one Type-A for media and charging, plus two Type-C for power only), a 12-volt socket under the front console, and two Type-C ports in the back. That’s plenty. 

Boot space is 410 litres (VDA), and the rear backrest split-folds 60/40 to liberate more room. Worth noting there are no tie-down anchors in the boot, but there is an underfloor storage compartment, plus a 45L ‘frunk’ under the bonnet of the RWD and a 14.5L storage space in the front of AWD models.

The boot lid is powered but there’s no spare, just a mobility kit. Grrrr!

If you want to hook up the tinny or camper trailer, towing capacity is 1500kg for a braked trailer and 750kg unbraked.

A bi-directional ‘Integrated Charging Control Unit’ (ICCU) allows for ‘Vehicle to Load’ (V2L) functionality on the inside and the outside of the car. There’s a house power-style three-pin outlet at the base of the rear seats or a simple adapter plugs into the charging outlet. Super-handy for camping, picnics, you name it.

Measuring 4695mm long, 1834mm wide, 1399mm tall and with a 2729mm wheelbase, the CLA 35 is definitely a sizeable sedan in the metal.

This actually makes the CLA 35 slightly longer and wider than a non-AMG C-Class sedan that measures 4686 and 1810mm respectively, but don’t expect the same level of practical interior space.

With a heavily sloped roofline, rear-seat comfort takes a hit. My 183cm (6.0ft) frame could not sit upright behind my driving position without tilting my head, while legroom was also slightly lacking.

With such large C-pillars and a small rear window, the second-row can actually feel a little claustrophobic for full-sized adults, but will seat children quite comfortably.

Second-row amenities include air-vents, two USB-C ports, back-of-seat storage nets, bottle holders in the doors, and two cupholders in the fold-down arm rest.

Just like at a music concert though, the best seats in the CLA 35 are up front, with plenty of room for heads, shoulders and legs.

The cabin is also much more light-filled up front, making for a more pleasant experience.

The front seats are electronically adjustable, as is the steering column, but the headrests are fixed.

Storage options include sizeable door bins, a centre console cubby, glove box, two cupholders and a wireless smartphone charger.

Boot space is 460 litres, but can expand with the rear split-fold 40/20/40 rear seats stowed.

Though the boot looks small and shallow on the outside, the aperture is actually quite large, and can easily accommodate a large suitcase with plenty of room to spare.

Priced at $85,500 before on-road costs, the CLA 35 sits $15,300 upstream of the CLA 250 but is $25,700 cheaper than the $111,200 CLA 45.

Standard equipment includes leather interior, dual-zone climate control, electronically adjustable front seats with heating and memory function, keyless entry and push-button start, 64-colour ambient lighting, and a wireless smartphone charger.

AMG specific appointments include 19-inch wheels, a flat-bottomed steering wheel, sports exhaust, high-performance brakes with silver-painted calipers, blacked-out exterior highlights, sports suspension, a racy bodykit and speed-sensitive steering.

Instrumentation is displayed on a 10.25-inch screen, which can be customised and features AMG readouts.

The multimedia system, which includes satellite navigation, digital radio and Apple CarPlay/Android Auto connectivity, is also outputted to a 10.25-inch screen, with inputs including touch, voice commands, centre touch pad or steering wheel controls.

Our test car also came with a ‘Mojave Silver Metallic’ paint finish and 'Vision Package', adding $1190 and $990 to the bottom line each.

The Vision Package adds LED headlights with adaptive high beams, a panoramic glass sunroof and surround-view monitor.

Straddling the lines between a small- and mid-size sedan, the CLA 35 doesn’t really have any direct competitors, which is reflected in its pricing that slots it between the Audi S3 and S4 sedans.

Though the CLA 35 features a long list of equipment, it is still a sizeable chunk of coin, costing more than the C300 sedan and Volvo S60 T8 PHEV, the latter boasting higher engine outputs.

The entry-grade Ioniq 6 is the rear-wheel drive Dynamiq, featuring a 168kW/350Nm permanent magnet synchronous electric motor on the rear axle powered by a liquid cooled lithium-ion battery.

The all-wheel drive Techniq and Epiq models feature an additional permanent magnet motor at the front for a combined output of 239kW and 605Nm.

Drive is fed to the wheels via a single-speed reduction gear auto transmission on the rear or both axles.

Powered by a 2.0-litre, turbo-petrol four-cylinder engine, the CLA 35 punches out 225kW/400Nm.

Drive is sent through a seven-speed dual-clutch automatic transmissions to the road via Mercedes’ '4Matic' all-wheel-drive system, enabling a 0-100km/h sprint in the 1603kg sedan in just 4.7 seconds. Top speed is electronically limited to 250km/h.

Though I didn’t get a chance to test the latter, the former certainly feels accurate when taking off from a freeway on ramp, however, there is some hesitation from the turbo in getting on boost.

Peak power comes in at 5800rpm, while maximum torque is available from 3000-4000rpm.

All versions of the Ioniq 6 carry the same 77.4kWh lithium-ion Polymer battery and the car’s 800V architecture allows it to use 350kW DC fast charging for a 10-80 per cent fill in 18 min.

The number of genuinely fast chargers available is increasing rapidly and that fill time is impressive.

Drop to 400V (50kW charging) and that time increases to 73 min, while 7.0kW AC charging from 10 to 100 per cent will take close to 12 hours.

The ports behind the not-fuel flap are a Type 2 for AC and CCS Combo2 for higher powered DC charging.

And if all else fails, you’re also equipped with a portable charger/cable so you can access house power for a full charge in, wait for it… 34 hours 20 min.

Quoted WLTP range for the RWD Dynamiq is 614km, that number dropping to 519km for the more powerful, dual-motor Techniq and Epiq models.

The WLTP combined cycle energy consumption figure for the Dynamiq is 14.3kWh/100km, with the Techniq and Epiq models at 16.9kWh/100km.

A ‘Disconnector Actuator System’ (DAS) on the front axle of the AWD grades is able to automatically engage and disengage drive to the front wheels as required, to reduce mechanical drag, lower energy consumption and increase driving range.

On test, in the Dynamiq, over a mix of suburban, b-road and freeway running we saw an average of 16.1kWh/100km which is a pretty good result.

Officially, the CLA 35 sips 7.5 litres per 100km on the combined cycle, but we managed a 9.9L/100km figure in our week with the car.

The majority of our driving was done in inner-city environments, with the two trips down the freeway to seek out twisty country rounds.

Minimum fuel grade in the CLA 35 is 98 RON.

Hyundai claims the RWD Ioniq 6 Dynamiq will accelerate from 0-100km/h in 7.4 seconds, which is not hanging around, and it feels every bit that quick. 

In fact, it has more than enough performance for sharp response in the city and easy cruising on the highway.

Step up to the AWD Techniq or Epiq and you’re hitting 100km/h in just 5.1 seconds, which is properly rapid. 

A single-speed ‘shift-by-wire’ reduction gear auto transmission sits on the rear or both axles and you have the choice of ‘Normal’, ‘Eco’, ‘Sport’ and ‘Custom’ drive modes, which fine-tune power output, accelerator response, steering weight as well as power distribution between the axles on AWD models.

Hyundai’s ‘E-Active Sound Design’ (e-ASD) changes the ‘sound texture’ as you drive with a noise roughly approximating Luke Skywalker’s Landspeeder coming through the speakers.

It’s fun for a while, but I found myself turning it down, then off, for the majority of the launch drive. And in that silent mode you can feel and hear (or not?) the impact of the car’s super-slippery shape. No wind noise and only modest tyre rumble at 110km/h on the freeway. 

The Ioniq 6 sits on Hyundai’s ‘Electric Global Modular Platform’ (E-GMP) which features the flat battery pack mounted low down, skateboard-style, between the axles. 

Suspension is strut front, five-link rear, and although the set-up hasn’t been tuned locally, Hyundai Australia says it’s been involved in the development. 

The front seat remained comfy after hours behind the wheel, but it must be said bumps and thumps from typical highway surfaces made their presence felt on a regular basis.

That’s not unusual for a full electric vehicle, but with the RWD Dynamiq riding on relatively cushy Hankook 225/55 ventus S1 evo3 rubber, it’s surprising.  

In corners you can feel the effect of the car’s low centre of gravity with the battery and motor(s) mounted low in the chassis. It hunkers down and remains beautifully balanced and secure through sweeping bends.

But even though the car points nicely, a meaningful connection between the front tyres and your hands on the steering wheel is MIA. 

The physical brakes are vented discs at the front and solid rotors at the rear, adjustable through ‘Normal’ and ‘Sport’ settings, and they’re nice and progressive.

However, there’s more fun to be had with the regenerative braking, adjustable through three levels (‘Strong’, ‘Medium’, ‘Soft’) via steering wheel-mounted paddle shifters.

Move to the highest setting and you’re in ‘i-Pedal’ mode which means for the majority of the time easing off the accelerator is all that’s required to wash off speed before coming to a reasonably prompt halt.

In terms of ergonomics, the simple dash layout works well thanks to a sensible mix of digital and physical controls, the head-up display is crystal clear, and the big screens for media and instrumentation are hard to fault.

A word of warning, though. An over-speed chime fires four times when you even marginally exceed the detected limit. It quickly becomes intensely annoying, the saviour being an off button in the vehicle settings menu. Downside is it defaults to ‘on’ every time you stop and re-start the car. Ugh!

The CLA 35 might not offer the outright thrills or breadth of capability of the CLA 45, but don’t think the cut-price AMG offers up a cut-rate driving experience.

From the driver’s seat, one of the cool things about the CLA 35 is that it doesn’t actually look any different from its more expensive sibling.

The drive-mode selector that is now embedded on the steering wheel is fantastic, a feature first seen on the Mercedes-AMG GT 4-door, and makes changing the driving dynamics on the fly an absolute breeze.

In fact, we think all cars where you can select drive modes should have a selector on the steering wheel like this, which lets you quickly and easily dial it up or down while keeping your hands on the wheel.

'Comfort', 'Sport', 'Sport+' and 'Individual' modes are available, while the transmission can also be put into manual mode independently for those that prefer to use the flappy paddles.

Suspension settings can also be tweaked regardless of which drive mode you are in, and it’s this level of customisability that we appreciate.

You want loud exhaust pops and the engine in full attack with manual shifting and the softest suspension? Sure, that’s doable here in the CLA 35. And toning it down to its most comfortable settings is just a flick of the wrist away.

The steering feels a little numb on centre and at slower speeds, though feedback picks right up with speed and is communicative enough when the road starts to get twisty.

Fitted with wide and sticky Michelin rubber, as well as the aforementioned all-wheel drive system, the CLA 35 is certainly not lacking in grip.

The suspension does an okay job of absorbing bumps, but uneven surfaces, like Melbourne’s tram tracks, can send uncomfortable jolts into the cabin if travelling quickly.

In fact, we think the ride comfort of the CLA 35 is probably its weakest aspect, offering not enough variability in its Comfort and Sport settings, and instead settling somewhere in between, regardless of drive mode.

The CLA 35 is ultimately still a fun and engaging sports sedan, though there are some sacrifices made to get it there.

The CLA 35 has not been tested by ANCAP or Euro NCAP, but the standard CLA range was awarded a five-star rating in September 2019.

Standard safety equipment in the CLA 35 includes autonomous emergency braking, automatic high beams, nine airbags, drive attention alert, blind-spot monitoring with exit warning, lane-keep assist, traffic sign recognition and tyre pressure monitoring.

The standard CLA also comes with these features, and was awarded 96 and 92 per cent respectively in ANCAP adult occupant and child occupant protection tests.

For the vulnerable road user and safety assist examinations, the standard CLA scored 91 and 76 per cent respectively.

ANCAP says the AEB system works from seven-200km/h.

Of note, adaptive cruise control is not standard in the CLA 35 like it is in the CLA 45. Instead, buyers will have to tick the 'Driving Assistance Package' box for the feature, which also comes bundled with cross-traffic alert and lane change assist.

Hyundai covers the Ioniq with a five-year, unlimited km warranty, with eight-year, 160,000km protection for the high-voltage battery. Both are industry standard these days.

There’s a lifetime servicing plan with maintenance intervals set at an impressive two years/30,000km. 

At this stage cost is $560 a throw, which is pretty handy when you consider the lengthy service intervals. 

A ‘Premium Roadside Support Plan’ is complimentary for the first 12 months and renewed annually while the vehicle is serviced by Hyundai.

Also complimentary is a ‘Sat Nav Update Plan’ which includes nine updates to be used within 10 years.

As with all new Mercedes-Benz models, the CLA 35 comes with a five-year/unlimited kilometre warranty, which is one of the best assurance periods offered by a premium carmaker.

It also comes with five years of roadside assist.

Scheduled service intervals are every 25,000km or 12 months, whichever comes first.

A three-year service plan is available for $2150 for new CLA 35 buyers, saving $500 when priced individually.

Four- and five-year plans are also available, and are priced at $4200 and $4950 respectively.
