Mercedes-Benz Eqc400 vs Kia EV6

What's the difference?

When I was telling my colleagues about the Mercedes-Benz EQC my summary was, basically, it’s the best electric luxury car I’ve driven. 

It’s plusher than a Jaguar i-Pace, more polished than a Tesla Model X - indeed, it feels like a different kind of electric car to both of those models. It’s an impressive foray into the segment, and we can’t wait for the chance to put it against some like-minded electric European luxury SUVs at some point in the future.

It’s fair to say the Kia EV6 is not the most affordable mid-to-large electric SUV money can buy. Especially in the era of cheaper Chinese models.

It also lacks some of the practicalities of a few rivals. If that’s your focus and you’re dead set on buying a Kia, then the EV5 is the clear choice.

But that’s not the sole purpose of this car.

It doubles as family transport and a car for driving enthusiasts. It’s the sort of EV that can convert EV non-believers.

After a week with the EV6, it’s not a car I’ll forget easily. And I urge buyers looking in the EV space not to overlook this pioneering model. It’s a brilliant car to drive and the GT-Line RWD is the value pick of the whole line-up.

The Mercedes-Benz EQC is entirely different to what we expect from the brand, but it’s really what we expected all along when it came to an electric SUV from the Daimler stable.

It is sleek, streamlined and smooth, with panels that almost look like they’re formed from liquid. And it has the eco-edgy graphics you’d expect, with a specific grille treatment (yes, a real grille), headlights that are unlike any other Benz (they even have an LED that runs the width of the grille), and a rear-end style that looks almost like it was penned with another Stuttgart-based brand in mind… Porsche. I’m talking about Porsche.

But one thing that I really love about the EQC is its moustache. It's more prominent when the car is finished in white paint, but there’s a moustache that former Daimler chief Dieter Zetsche himself could be envious of. And he had one helluva soup strainer.

It is clearly made to be slippery, despite essentially sharing its underpinnings with the more conventionally angular - yet still rounded-edged - GLC SUV.

While it is a nicely styled gizmo, I found there are some things that could be annoying.

For instance, I was trying to plug in at night in a dark area, and while there is a small light above the charge port, other EVs have a light that actually illuminates the area where you’re plugging in. 

And also, the plug port is on the driver’s side. If, like me, you had to charge up with the car on the street, it just adds a little bit more anxiety to the whole situation. I shudder to think what could happen if the charger was hit by a passing car - folding the mirrors in is one thing, but you can’t fold the power cable! The lead for the charger is long, thankfully. 

I know, most people (maybe even all people!) who buy and EQC are going to have undercover parking in a garage or carport, but it’s still worth remembering that the filler isn’t on the kerb side like a number of other EVs. 

It has almost identical dimensions to that car: 4774mm long on a 2873mm wheelbase, with a width of 1884mm and a height of 1622mm. For context, GLC is 4669mm long, same wheelbase, a bit wider (1890mm) and just a little more height (1639mm).

What about interior design? Well it’s also familiarly different, with a number of changes to the materials used but still the same tech and comfort you’d expect. Check out the interior images in the section below.

When I first saw the Kia EV6, I have to admit I wasn’t a massive fan of the design. I was, and still am, a massive fan of the mechanically related Hyundai Ioniq 5. Perhaps one of the many reasons that model won Best Medium SUV Under $130,000 at the 2026 CarsGuide Car of the Year Awards!

But the 2026 facelift has given me a renewed appreciation of the Kia’s design.

The overall shape is the same but the front, which was arguably its least appealing angle, has been redesigned.

It’s 15mm longer thanks to the new front bumper design, and it has adopted a completely new headlight signature that's in keeping with the EV3, EV4, EV5 and EV9. The front looks meaner, more aggressive, but in a really hot way.

There’s also a new bumper at the rear but the tail-lights are pretty much the same.

Overall it’s a much sharper look, helping to breathe new life into the EV6.

The visual changes are more subtle inside, but it was already a nice cabin to begin with. The big changes include the new version of Kia’s dual-screen set-up which is more modern and centred than the previous version, and there’s more visually appealing graphics.

The other key change is the steering wheel. For GT-Line and GT grades, Kia’s dropped the polarising two-spoke wheel in favour of a sportier and more premium three-spoke, dual-tone wheel found in other models, including the EV3. The base Air retains the two-spoke wheel.

If you’re thinking the EQC looks like a seven-seat SUV, you’re wrong. It’s a five-seater, with a decent sized boot, too.

The luggage capacity is 500 litres, which is decent for a car of this size, but bear in mind there is no spare wheel under the boot floor. 

Rear seat space is reasonably spacious for someone my size (182cm) sitting behind their own driving position, with decent knee and toe space. Headroom is not terrific, though, and anyone taller will need to watch their head as they get in and out of the car as the top sill eats into space quite a bit. 

Any middle-seat passengers might find the room a little less likeable, as the transmission tunnel intrudes quite a bit. Those with big feet might find shoehorning themselves in and out a bit of a challenge as the sills are quite large, and our car even had optional ($1200) “aluminium-look running boards with rubber studs” - side steps, essentially. They get in the way, too.

But if you’re just sitting two abreast in the back the seat comfort is really good, the trim quality is excellent, and there is a flip down armrest with the storage bin and pop out cupholders. There are rear air vents (no climate control adjustment in the back, though, and no USB charging either), and there are two map pockets, plus bottle holders in the doors. Up front you will find a mix of familiar elements if you’ve sat in any recent Benz model, but a few unique finishes and trim elements that might be new to you.

There’s a beautiful horizontal fin theme that runs around the cabin, as well as the now-traditionally audacious looking Burmester sound system speaker covers. They don’t quite gel with the aesthetic, to my eye. 

The dash-top material - “fine surface texture”, as Benz calls it - is unlike anything else we’ve seen from the brand, it’s kind of like a soft silky slippery fabric trim. While there are lovely copper trim elements that just add something visually entertaining and appealing to the space.

There is a large covered centre console bin with 2x USB-C charge points and there is an additional USB-C upfront next to the wireless phone charger. The Mercedes touchpad system that aligns with the MBUX media screen is reasonably easy to get used to, but being a Benz there are plenty of options for usability - the centre screen is a touch-capacitive unit, or you can use the steering wheel-mounted controller on the left side of the wheel to control the middle screen. The right thumb controller manages the driver info screen.

It was mostly very easily managed, although the menus did get stuck at times for me - mainly in the section around the energy consumption. Plus I tried the whole “Hey, Mercedes” command thing, and it failed on numerous occasions. 

Under Australia’s vehicle categorisation, the Kia EV6 is classed as a large SUV. Which is not correct. Yes, it’s long and wide but it isn’t large. It’s medium. Also, is it an SUV? Or is it a low-slung coupe-style fastback? Perhaps a bit of both.

The EV6 has a decent amount of space in the cabin, but family-friendly practically might not be its strongest suit.

In the front row, headroom is limited. The sunroof is partly to blame for this, but the EV6’s front seats have always felt a little cramped for taller folks. Finding my perfect driving position took a bit longer as a result. Popping your sunglasses on your head is a no-no for a six footer like me. There is, however, plenty of space across the front of the cabin.

The front seats offer excellent upper body bolstering but could do with a little more for the thighs. But they are delightfully comfortable and look gorgeous.

The elevated centre console provides a high-set armrest and under that is a massive central bin, then there is a huge amount of open space underneath.

It houses two shallow and narrow cupholders with a phone charger, gear shifter, vehicle on/off and seat/steering wheel heating buttons. Yay buttons!

Climate control is managed via a digital panel separate to the main screen. It features smart dials that switch between air con and audio and sat-nav controls. Speaking of which, the air con flow is excellent.

Kia’s updated multimedia system brings it into line with other newer models. It’s a pleasure to use this system. Large tiles drill down into logical sub-menus, you can swipe every which way and the resolution is excellent. It’s also easy to navigate.

There are three USB-C charge ports under the centre stack.

Taller passengers might need to duck their head when getting in the second row, due to the lower sloping roofline. Once seated, the EV6 features that quirk of some older EVs where the rear seats are heavily bucketed and your knees sit up high because of the positioning of the under-floor battery. A lot of newer EVs keep the rear footwell free of battery packs to ensure more foot room and a more comfortable rear-seat experience.

There’s heaps of leg room behind my seating position, and headroom isn’t bad back there. It’s certainly better than the front. I had about 2.0cm between my head and the roof liner.

It feels a little dark back there due to the high window line, privacy glass and small rear window.

The rear seats are comfy but on the firmer side. There’s a fold-down arm rest with two shallow cupholders, and a small bottle will fit in the door.

You get two map pockets, USB-C ports on the back of both front seats, and chest-level side air vents.

You can lower the 60/40 split rear seats via a lower lever on the seat base. They fold almost flat, too. You can also lower the seats via a lever in the boot which is a handy feature.

The EV6 Air RWD’s boot can swallow 490 litres of cargo, and that drops to 480L for all other grades.

The boot area allows for a decent amount of usable space but the sloping tailgate means you won’t fit tall items.

Under-floor storage is limited but could easily fit flatter items like a charging cable. It also houses the tyre repair kit which is sadly what you get instead of any form of spare wheel. The boot also has a number of bag hooks, speakers and a light.

A front storage compartment under the bonnet can take 52 litres in the RWD grades, dropping to 20L in AWD versions.

One of the challenges for Kia and the EV6 is price and positioning. In the four years since its launch, the price of EVs of a comparable size has come down considerably.

You can get a medium-to-large electric SUV in the low-$40K range these days from one of a number of new Chinese players.

But not many of those cars have the same focus on driveability as the EV6.

Wisely, Kia has kept prices essentially as they were as part of the 2026 facelift. Each grade has only gone up by $70 apiece.

The EV6 kicks off with the Air RWD (rear-wheel drive, single motor) from $72,660, before on-road costs. The GT-Line RWD (the grade I will focus on for this review) costs $79,660 and the GT-Line AWD (all-wheel drive, dual motor) is $87,660 - an $8000 jump from the RWD.

It tops out at $99,660 for the performance-honed GT.

This pricing puts the EV6 somewhere between the new crop of affordable EVs like the BYD Sealion 7, Zeekr 7X and more premium offerings like the BMW iX3 or Audi Q4 etron.

It’s closer in price to another sporty EV, the Cupra Tavascan ($60,990-$82,490), as well as the Kia’s mechanical cousin, the Hyundai Ioniq 5 ($76,200-$115,000).

The facelift ushers in new standard gear including fresh 19 to 21-inch alloy wheel designs, vehicle-to-load (V2L) functionality, new twin 12.3-inch driver and multimedia screens, updated software with enhanced graphics, wireless Apple CarPlay and Android Auto (it was previously wired) and over-the-air updates.

Other standard gear in the base Air includes reclining rear seatbacks, synthetic leather seats, manual front seat adjustment, five USB-C ports, a wireless phone charger, a retractable cargo cover, six-speaker audio, digital radio and dual-zone climate control.

The GT-Line RWD I am testing adds a 14-speaker Meridian audio system, heated and ventilated front seats, a heated steering wheel, ambient lighting, alloy sports pedals, a sunroof, hands-free power tailgate, eight-way power driver and front passenger seats, synthetic black suede/white leather seats and remote park assist.

The flagship GT gains special sports bucket seats, two more USB-C ports in the rear, heated rear seats and a bigger dollop of performance.

When you look at the base pricing compared to the fully-loaded standard kit of the more affordable EVs, it doesn’t look like great value. But the GT-Line RWD is the pick of the EV6 grades as it isn’t missing much. You could also argue the overall build quality, gripping performance (more on that in the Driving section), reliability and Kia’s extensive dealer network is worth the extra spend.

The EQC has a power output of 300kW and it has 760Nm of torque, which is enough to see its claimed 0-100km/h acceleration pegged at just 5.1 seconds.

The EQC’s top speed is 180km/h (limited for the sake of the batteries), and it has an 80kWh lithium-ion battery pack.

It uses a pair of asynchronous motors - one front, one rear - and they can alternate to do what’s best in the situation - be it working in 2WD (RWD or FWD), or in AWD. 

If you’re thinking about an EQC as a towing option, the towing capacity is 750kg for an un-braked trailer and 1800kg for a braked trailer.

The EV6 has a range of powertrains depending on the grade. The Air and GT-Line RWD have a single motor set-up offering 168kW of power and 350Nm of torque, and the GT-Line AWD dual-motor pumps out 239kW and 605Nm.

Kia has boosted power in the high-performance GT by 18 kilowatts to a bonkers 448kW.

These figures are higher than some cheaper rivals and on par with other similarly priced EVs.

The 0-100km/h sprint time for the rear-drive grades is 7.7 seconds, dropping to 5.3 seconds for the GT-Line AWD, while the GT can do it in a blistering 3.5 seconds when engaging Launch Control.

With an 80kWh battery pack and a Type 2 CCS plug (up to AC 7.4kW / DC 110kW) the charge times vary pretty greatly depending on what output you’re powering up from.

Mercedes-Benz says a DC fast charging station should be able to replenish the battery bank in 1 hour 22 minutes (at a maximum of 110kW, though some Chargefox stations offer charge rates up to 350kW) while an AC charging station (like you’d find in car parks) or Mercedes-Benz’s own Wallbox system should take about 12 hours 13 minutes.

Charging from a regular household powerpoint is a last resort option. It is claimed to take 46 hours 40 minutes from empty to full (230-volt outlet, 10-amp/2.3kW). I plugged in to a powerpoint in my house and the car’s info display was stating it would take 9.5 hours to achieve the remaining 16 per cent of charge. It didn’t get to 100 per cent before I had to unplug, however.

My not-so-urban test drive loop commenced with 97 per cent of battery charge and an indicated range of 363km available. The idea was to get a feel for the “range vs reality” of the situation, so I did it in Comfort drive mode with the climate control active and no intent to either thrash the vehicle or baby it to save battery.

My drive ended with 36 per cent indicated charge remaining, after I’d covered 231.6km. That means, based on the car’s own algorithm, that it would have covered 315km before the battery was depleted, which is a long way short of the claimed 434km range.

The indicated energy consumption was 20.8kWh/100km, which is ‘thirsty’ for an EV. On our recent electric car comparison test, the most efficient of our EVs - the Hyundai Ioniq Electric - used just 13.0kWh/100km. Yes, I know the EQC is a lot heavier (2425kg kerb weight), but even the Tesla Model 3 was notably more efficient (18.5kWh/100km) than the EQC over very similar terrain and driving.

However, our testing saw us return an even better consumption rate than Mercedes-Benz’s claimed figure, which is 21.4kWh/100km.

All EV6 grades get a bigger under-floor lithium-ion battery, up from the 77.4 kilowatt hour unit in the previous model to 84kWh.

Driving range is up more than 50km in rear-wheel drive variants to 582km in the Air and 560km in the GT-Line, according to the WLTP testing cycle.

The GT-Line AWD’s range is now 522km (up from 484km), and the range-topping dual-motor GT offers 450km of range - a 26km increase.

All EV6 grades have vehicle-to-load charging via a port under the rear seating row or by using an extender for the external CCS Type 2 charging port.

Maximum DC charging is 10.5kW but the EV6 supports AC charging infrastructure up to 400 and 800 volts.

Using a 50kW fast charger should take 80 minutes to get from 10 to 80 per cent full, while a 350kW charger takes 18 minutes. Slow AC charging at home with three-phase power should take about seven-and-a-half hours.

Official energy consumption varies between grades. The Air RWD is 15.9kWh/100km, GT-Line RWD is 16.9kWh, GT-Line AWD is 17.7kWh and GT is 20.9kWh.

The car’s trip computer recorded an efficiency figure of 19.1kW/h when I handed it back, but I engaged in some enthusiastic driving. Factoring in the usable battery capacity (80kWh), the EV6 GT-Line RWD’s theoretical range is 473km.

It has multi-mode regenerative braking that is exceptionally smooth, including one-pedal driving, various EV sounds to choose from and a utility mode function to save battery life.

There’s even a soft close function for the charge flap that’s integrated nicely in the driver’s side rear tail-light.

If you have a garage and a Wallbox connector, there’s no reason the Mercedes EQC couldn’t be a terrific option as a commuter, a second car, or even your primary vehicle. 

The thing with all electric cars is that it’s about settling into a rhythm. If you use the car to commute to work, maybe you can charge it there. Or you might have a solar array and charge at home.

No matter the situation, you’ll be getting a rather nice vehicle to live with, based on my week with the EQC.

It’s a plush car, that’s for sure. The silence it offers is truly relaxing, and there’s effortless torque to pull you away from a standstill. The way you can build pace to overtake, the rush of noise-free acceleration, is pretty astounding. Perhaps not as visceral as in a GLC 63 AMG, but it’s still an experience.

The steering is direct and doesn’t require much thought, though it does lack a little bit of feel. But it’s easy to predict and quick to respond, making for pleasant progress around town. It’s easy to park, as well, with a great surround view camera system, as well as front and rear parking sensors. And if you’re not confident, the car has semi-autonomous parking, too.

The brake pedal feel takes some acclimation, because it responds pretty well, but the action is hard to modulate at times. That is partly due to the brake regeneration system, which actively captures energy that would have otherwise been lost during braking. You can adjust the level of aggression of the regen brakes, too, by tapping either the up or down shift paddles. The most aggressive setting will almost pull you up to a halt from urban speed without any brake pressure required.

The suspension of the EQC feels more settled than the last GLC I drove, and that could be in part due to the extra weight and stiffness of the battery cell under the body. The centre of gravity feels low, and it feels stuck down to the road in most situations.

The ride is mostly fine, but with big 20-inch wheels and low profile tyres, it can jar on hard edges. I also noticed that it can feel a bit unsettled at higher speed, as the body moves around - from side to side - more than I would have expected. It deals well with undulation changes and big dips, and if the surface is good, so are the comfort levels in the cabin. 

This is where the EV6 excels. There’s a lot more competition out there now, but the good news is the EV6 still impresses on the road.

I am purely focusing on the GT-Line RWD for this section as it’s the grade I had for a week.

It’s not brutally quick from a standing start, but it offers a nice, linear build up of speed. It adds speed quite quickly when at pace and this is more than enough poke for most people.

If you are intent on more power and speed, but without stretching to the GT flagship, the GT-Line AWD might be your cup of Jarrah. Although that is an $8000 premium over the RWD.

If you want to save the cash the RWD has drive modes ('Eco', 'Normal', 'Sport', 'Snow', 'MyDrive'), so you can add some spice with Sport mode.

The EV6’s precise steering has a little weight to it and good feedback.

On dynamically engaging roads the EV6 doesn’t feel its two-tonne weight. It has loads of grip when you lean into a corner and remains flat through the twisty stuff. There’s the tiniest hint of lateral movement in the car but there’s a lack of top-heavy body roll.

Thanks to the rear-wheel drive configuration, it’s also playful. The rear flicked out briefly when turning in wet conditions, but otherwise the stability control keeps everything in check.

This car has clearly been engineerd by driving enthusiasts for driving enthusiasts.

The ride quality is a little jittery on uneven roads. It’s not cushy like the EV5. You will feel tram/train tracks, potholes and random bumps. I detected a little vibration through the steering wheel on crumby roads. The Continental Premium Contact 6 (255/45 R20) tyres have a decent sidewall but they can’t soak up everything.

As well as being dynamically excellent, it’s also a lovely cruiser on smooth freeways and roads.

Other related points - it has a large turning circle (11.6m) and visibility is impeded by enormous B- and C-pillars, small rear windows and a middle-seat headrest.

The EV6 doesn’t gain anything too new from a safety perspective with this update but it comes standard with the usual driver aids like auto emergency braking with car, pedestrian, cyclist and junction turning, lane keep assist, ‘Lane Following Assist’, blind-spot collision warning and assist with rear cross-traffic alert and assist, safe exit warning, multi-collision braking, adaptive cruise control, a speed limiter, reversing camera and front and rear parking sensors.

The lane keeping aid tugs a little at the wheel and it subtly moves the car to the left line marking on motorways, but it’s not too intrusive.

There are seven airbags including a side centre airbag, three top tether anchors and two ISOFIX points.

The EV6 was awarded a maximum five-star rating from ANCAP back in 2022 and that rating should carry over until it expires at the end of 2028.

As with any modern Kia - or Hyundai and Genesis for that matter - I turn off a bunch of the driver aids as soon as I get behind the wheel to ensure I remain sane. Thankfully, there is a configurable favourite button (a star) on the steering wheel that takes you straight to the driver safety menu, otherwise you have to dig through multiple menus.

I turn off the infuriating overspeed warning and the driver attention alert every single time I drive this car because they are so deeply annoying.

If safety features are too distracting to leave on, are they really safe?

It mightn’t have the same method of propulsion as a petrol or diesel Merc, but it has similar service requirements. You still need to take it to the workshop for maintenance every 12 months - or every 25,000km! - whichever comes first.

Owners can either pay as they go for servicing, or pay up front and bundle it into their finance. The upfront rate is $1350 for three years/75,000km. Pay as you go will peg you along at $450 (year one), $750 (year two), $450 (year three). 

When the EQC launched it came with a three-year/unlimited kilometre warranty plan, but that was recently updated to a five-year/unlimited km plan, bringing Benz inline with the likes of Korean luxury maker Genesis, not to mention the majority of mainstream car brands.

The EV6 is covered by Kia’s solid seven year/unlimited kilometre warranty and it has a battery warranty of seven years or 150,000 kilometres, whichever occurs first.

The service schedule is every 12 months or 15,000km.

Kia offers service plans of three, five and seven years with pricing for Air and GT-Line of $728 for three years, $1391 for five years and $2055 for seven years.

The GT is a little pricer at $842, $1570 and $2319, respectively.

This pricing isn’t astronomical, but it is more expensive than the Cupra Tavascan and MG IM6.

Kia has 147 dealerships across the country covering metro, urban and rural areas and all of them service EVs.
