Kia EV6 vs Mercedes-Benz EQB

What's the difference?

The Kia EV6 Air offers comfort, a good range of features and beautiful handling for a ‘base model’, but it is a little pricey considering its competition.

Having said that, if you’re looking for an EV that will fit the family and has a stellar safety list – this is one to consider.

My son reckons the EV6 looks 'really cool' and he loves the space in the back seat.

I really liked the combustion version of this car, the GLB, for its funky style and flexibility and I was pleased to find how easily Mercedes has made the conversion to a fully-electric layout for the EQB.

Despite a tall price, the EQB 350 is a compelling option for those seeking something a bit more luxurious than the Tesla Model Y, something a bit larger than the Volvo XC40 Recharge, and something a bit smaller than the Audi e-tron or the EQC.

The main trade-off for this 350 variant is the loss of the seven-seat layout in favour of more performance. Instead it offers a huge boot, has a sufficient range for city-based buyers, and offers surprising levels of fun, too. 

Just make sure you’ve considered its rivals which may potentially offer more range or features for the same money.

The EV6 is cool and fun-looking, but being the base-model does mean you get plastic rather than body-coloured mouldings around the base of the car, which highlights its grade level.

The exterior hosts 19-inch alloy wheels and a full suite of LED lights but misses out on the upgraded Matrix headlights that the higher grades get.

The exterior's swoopy curves look aerodynamic and the chunkier rear balances out the sharper nose.

The interior looks well-made, and the mix of high-end cloth and synthetic-leather materials complement the futuristic exterior aesthetic.

The dashboard is headlined by a curved panel that houses the dual 12.3-inch tech screens and the floating centre console leans into that future vibe again.

There's a nice mix of touchscreen and physical buttons to satisfy a wide audience. Overall, while it’s not as flashy as its siblings, the cabin of the Air is very pleasant to look at.

The EQB has a very predictable design in that it doesn't stray from the combustion car’s formula. At all.

The only evidence from the outside this is the electric version is the blanked out grille, and closer observers might notice the rear light bar which cuts across the boot lid is different from the split tail-light design which appears on the combustion car.

Still, to my eyes, the GLB is a cool design with its upright boxy look bucking the curvaceous trend of most EVs, and, indeed, the rest of the Mercedes line-up. 

Its rebellious streak makes it one of the most appealing SUVs in Mercedes’ current range, and it comes with a bit of toughness which is missing from the EQA. 

If nothing else, it’s a completely different look from Tesla’s amorphous Model Y, and this may be enough to appeal to some.

Inside is identical to other Mercedes models which sit on the MFA2 small car platform, immediately setting itself apart with the big high-resolution screens, glitzy ambient lighting, as well as an abundance of chrome and gloss black.

It’s designed to impress from the first time you hop in, and there’s no doubt it does, but it may be a bit over-the-top for some, particularly fans of the more conservative Mercedes designs of eras past.

The chrome in particular becomes a bit of a problem, as it has an annoying habit of catching the reflection of the sun and sending it directly into the driver’s eyes.

It all feels as plush as a circa-$100,000 luxury car should though, with the ‘Artico’ seat trim being one of the better synthetic options on the market, and soft-touch surfaces throughout the cabin selling the Mercedes promise. 

The GLB toughness is even reflected in the chiselled out finishes in the door, dash, and centre console, helping to set it apart from the tamer EQA.

The software is also fast, high resolution, and well presented, which bodes well given the amount of screen real-estate, and the amount of customization is impressive, too.

Again, there are many who will prefer its look and feel to the Apple-store chic of the Tesla Model Y, or the pared back Scandinavian approach of the XC40 Recharge, but also those who won’t. Like many new Mercedes products, it continues to polarise buyers.

The space in the EV6 rivals much larger SUVs and tall families will rejoice with how much leg- and headroom you get in both rows.

The comfort for passengers is pretty good, with comfortable seats in both rows that feel well-cushioned. The floor in the rear is flat, which accommodates any middle-seaters.

Being the base grade, you don’t get electric front seats, which is a bit rough for its price point but the driver’s side does get powered lumbar support, which I appreciate on longer journeys.

Individual storage is fantastic for the class and the front gets two cupholders, a drink bottle holder in each door and glovebox and middle console. There are multiple storage nooks and a utility tray on the topside of the floating centre console (sized for items like keys, wallet, phone etc).

The large shelf underneath the centre console easily accommodates a handbag and snacks for any kids in the back (or adults, no judgement).

Individual storage in the back is as good as the front, with plenty of spots to tuck away all of the paraphernalia that kids seem to attract. There are also two cupholders in a fold-down armrest, a drink bottle holder in each door and map pockets.

On the whole, my seven-year-old really enjoys being in the back seat because of the amenities and space he has. He finds the EV6 to be an easy car to get out of but we all struggle with the flush door handles! They can be terribly annoying to use as they don’t pop out on approach or when you unlock the doors. If you have your hands full and have little T-Rex hands like me, it can be awkward to open.

What isn't awkward to use is the technology! The 12.3-inch touchscreen multimedia system is quick to respond and the system itself is easy to navigate once you spend some time with it.

The 12.3-inch digital instrument cluster is semi-customisable but not as pretty in its graphics as it could be. It has two styles to choose from - white or black, and the white is a little too sterile for my liking.

The multimedia system features wired Apple CarPlay, Android Auto and built-in satellite navigation with map updates for 10 years.

Charging options are solid with a single USB-A and and two USB-C ports up front, a wireless charging pad and a two 12-volt ports to choose from. The rear enjoy a three-pin standard house port and two USB-C ports as well.

The back seat has a 60/40 split and it's handy that you can lower them from the boot with manual levers. The boot itself is a good size with 490L when all seats are in use but you miss out on a powered tailgate in this model.

The frunk storage also offers an additional 52L, which is perfect to keep any charging cables or the tyre mobility kit stored away.

This should be the GLB’s calling card. It’s a car with an ideal footprint, not as wide or as long as most mid-size SUVs, whilst also offering a larger cabin and boot.

The big drawback for this variant in particular is the lack of a seven-seat option, as the all-wheel drive requires the under-floor space which is required to give rear occupants legroom. 

It’s a shame, too, because I found the two rear seats in this car’s GLB combustion equivalent to be surprisingly accommodating for even adults.

As a result of these missing seats, though, the full volume can be exploited in the boot, which comes in at a whopping 495 litres.

It’s rivalled by the Model Y, which also has a cavernous boot, although it has a much larger storage area than the Volvo XC40. 

As an added bonus, there is a decent under-floor storage area which has enough space for all your charging cables, although there is no so-called ‘frunk’ with what is normally the engine bay taken up by cooling and auxiliary hardware. 

At first glance there’s so much going on under there, you’d be forgiven for thinking the EQB has an actual engine!

The cabin is also enormous as well as configurable. The EQB has massive rear doors (as it’s designed to be a seven-seater) to make it easy to get in and out of, and once you’re settled in, the amount of space for me (at 182cm) behind my own driving position is very impressive, with ample leg, arm, and headroom.

Rear passengers score the same nice synthetic leather seat and door trim as the front passengers, a bottle holder in each door, as well as two in a flip-out caddy on the drop-down armrest, two nets on the backs of the front seats, dual adjustable air vents, and power outlets on the back of the console. There is also a separate section of the split sunroof to benefit those in the back seat.

Up front the cabin is equally flexible, although it immediately seems odd that the front seats are manually adjustable. Almost unforgivable in a $100,000 car. 

At least the trim is comfortable, and again, the space is configurable for people of all shapes and sizes. 

Storage options include large bins in each door, a split-opening armrest console with USB-C outlets inside, a slide-open area underneath the climate unit, which houses a wireless phone charger and additional power outlets, as well as the usual glove box arrangement. 

Soft trims continue into the doors, although one small annoyance is the excess of chrome trim which has the unfortunate habit of reflecting harsh Australian sun into your eyes if it hits at the wrong angle.

The software is nice and quick, but can be cumbersome and over-complicated to operate at times, particularly when using the centre touchpad, or adjusting the dash with the small touch elements on the wheel. 

It is also notable the Apple CarPlay as-tested only took up a centre portion of the screen, and is not set-up for widescreen mode to take full advantage of the hardware.

Minor complaints aside, though, the EQB follows its combustion GLB twin in having by far one of the most flexible and configurable cabins in its class.

The EQB range kicks off from $87,800, before on-road costs, for the base 250, but the car we’re looking at for this review is the top-spec 350 4Matic, which wears a price-tag of $106,700.

There’s no doubt it’s a hefty price, even for an EV, and especially for a sort-of ‘small’ SUV. There’s more to consider, too. As I mentioned in the intro, the all-wheel drive system precludes the seven-seat layout in this top-spec car, and it has less range than the front-wheel drive model, too, dropping from 371km to 360km.

On the upswing, the dual-motor powertrain is far preferable to the so-so front-wheel drive option, and the 350 also gains an AMG-spiced bodykit and flat-bottomed steering wheel, as well as a panoramic sunroof.

Outside of the extra flair, the EQB 350 is almost as well equipped as you could hope, with the flashy dual-10.25-inch 'MBUX' screen set-up, Nappa leather steering wheel and interior appointments with Mercedes’ signature 'Artico' synthetic seat trim, LED headlights, ambient interior lighting with fully customisable RGB controls, dual-zone climate, a wireless phone charger, 20-inch alloy wheels, as well as keyless entry and push-start ignition.

Given the EQB’s dimensions it would seem its most direct rival is the Tesla Model Y, although it may not be a favourable comparison. 

At over $100,000 the EQB 350 is still more expensive than the top-spec Model Y Performance, which is even more powerful than our Merc here.

Other more indirect rivals include the Volvo XC40 Recharge (from $74,490 in twin-motor form), or less performance-oriented Lexus UX300e ($80,691 for the top-spec Sports Luxury), although neither are as large as the EQB, and the Lexus has about half the performance.

The EV6 Air is a single-motor rear-wheel-drive that produces a maximum power output of 168kW and 350Nm of torque.

The Air has the slowest 0-100km/h sprint time in the EV6 range at 7.3 seconds, but that’s honestly enough for my little family. It still feels pretty damn zippy when you put your foot down.

While the EQB 350 loses its valuable third-row seats, it gains a much more impressive drivetrain than the lesser EQB 250 variant. 

While that car has a so-so front-motor set-up producing 140kW/385Nm, the top-spec 350 sports a much more capable 215kW/520Nm dual-motor system.

This allows a 0-100km/h sprint time of 6.2 seconds, and while it’s not as fast as the entry-level Tesla Model 3, it’s still impressive for a 2153kg SUV.

The all-wheel drive capability also adds a level of confidence which can’t be matched by a front-drive, more on this in the driving section of this review.

Officially, you get a driving range of up to 528km (WLTP) from the 77.4kWh lithium-ion battery. However, the longest range I ever saw was 480km, which admittedly is still very good.

The EV6 Air has a Type 2 CCS port, which means you can benefit from plugging into a fast charger and the accepted voltage is a whopping 800v.

On a 50kW system, you’ll get from 10-80 per cent charge in 73 minutes and on a 350kW system, which charge time drops to just 18 minutes.

Expect it to take longer on AC charging, though. To get from 10-100 per cent on an 11kW system, it will take approximately seven hours and 20 minutes. On a standard house plug ... expect it to be on charge for around 30 hours.

The Air also has a vehicle to load (V2L) capability – meaning, it has a standard house three-pin plug port available to charge larger appliances while on the go. 

The official combined energy consumption is 16.5kW/100km (WLTP), and my usage came out at 16.02kW after a mix of open-road and urban driving this week.

Regardless of which version of the EQB is chosen, the SUV has a 66.5kWh lithium-ion battery pack, and in the case of our all-wheel drive 350, this grants it a 360km WLTP-rated driving range between charges.

My car was reporting around 350km of range at or near a full charge, while my week of testing produced a dash-reported consumption figure of just 18.2kWh/100km.

This is surprising for two reasons. Firstly, I subjected the EQB 350 to a significant amount of freeway testing during my time with it, which usually produces worse consumption numbers for EVs, but it actually bested its official 21.0kWh/100km official figure by a decent margin.

Secondly, I’m puzzled to find this car outperformed the smaller and lighter EQA 250 I had on test in 2021 in terms of overall consumption, and by a significant margin. Very odd.

When it comes to charging up, the EQB can be charged at a rate of 100kW on a fast DC charger, for a 10-80 per cent charge time in a claimed 30 minutes. 

On the slower but cheaper-to-install AC standard, the EQB has an 11kW inverter, allowing a convenient ‘slow’ charge time of 4.1 hours. Expect between 25 and 30 hours on a standard wall socket.

The EV6 Air handles itself really well, it's been hit by torrential rain and didn’t skip a beat.

The Air really grips the road and distributes the power through the rear wheels evenly. Even at higher speeds, there’s no wobble and it feels stable when you accelerate. 

Steering is on the right side of firm and makes the Air feel very zippy when navigating tight city streets.

There are three levels of regenerative braking available, as well as a one-pedal function called iPedal, which is probably the best I’ve sampled and I like how responsive it is in stop-start traffic. However, when using this function on hills, I still hover over the brakes as it can still roll forward a bit. 

The cabin can get really loud from road noise at higher speeds, but it seems to come from underneath the carriage, rather than through the windows. The suspension is well-cushioned but not spongy.

Parking the EV6 isn’t an issue once you get used to the rotary gear selector and the reversing camera is super clear. You get a 360-degree system on higher grades but the Air does come with front and rear parking sensors.

This is where the 350 version of the EQB shines. This car is a beast to drive with plenty of power available at your right foot, and incredible amounts of traction to match from its torque-vectored all-wheel drive system. 

This lets it be rapid, but not scary, and despite its square and upright body, might surprise you when it comes to carving a few corners.

Like many EVs, the EQB’s weight feels low and centred, but it appears the suspension has been adjusted to remove any bouncy quality, which might come with the additional weight added over the combustion variants, with nearly 500kg of lithium batteries under the floor.

In fact, the ride is also one of the things which impressed me most about the EQB. It even has huge 20-inch AMG wheels, yet it dealt with bumps of all shapes and sizes in an impressive manner, keeping the body under control, and communicating remarkably little in terms of vibration or unpleasantness into the cabin.

The steering offes a nice balance of feel and electrical assistance, a trait which combines with the EQB’s convenient size to make for an easy SUV to park and manoeuvre.

When it comes to the EQB’s traits as an electric car, there are several modes available to alter the experience. 

Using the paddle shifters, there are several regenerative braking settings to choose from. While none of them are a ‘single pedal’ mode, the D- mode is pretty strong, and clearly contributed to the EQB’s surprisingly good energy consumption in my time with the car.

Activating D+ mode, which can be combined with a sporty driving setting, tones down the regenerative setting almost completely and feels as though it unleashes more potential from the potent electric motors. 

While the sportier settings made the 2WD EQA I tested last year feel a little twitchy and prone to wheelspin, the all-wheel drive system keeps this well under control in the larger EQB for impressive acceleration characteristics.

The breadth of this SUV’s ability is perhaps its most impressive attribute. It can feel comfortable and tame around town, with alarming speed and tenacity when attacking the open road should you so desire. 

Sure, it’s not as whiplash-inducing as some of its rivals, particularly the Volvo XC40 Recharge or Tesla Model Y, but for a luxury SUV like this it’s more than what you could ask for. 

The EQB scores a thorough suite of active safety equipment including freeway-speed auto emergency braking (7.0-200km/h), lane keep assist with lane departure warning, blind-spot monitoring with rear cross-traffic alert, as well as one of the best adaptive cruise systems on the market.

In the event of an impact, the EQB scores dual front, side, and head curtain airbags (the side and curtain bags cover both rows) as well as a driver’s knee airbag. There are the usual dual outboard ISOFIX child seat mounting points on the rear row, as well as three top-tether points.

The EQB scored a maximum five-star ANCAP safety rating to the current 2022 standards, but this rating only covers the base 250 variant. It scored highly across all criteria.

The EV6 comes with a leading seven-year/unlimited-km warranty. The battery covered by a separate seven-year/150,000km term, but this is a smidge shorter than some of its rivals.

You can pre-purchase either a three-, five-, or seven-year servicing program, priced at $721, $1382 and $2045, respectively. All of which are reasonable for the class.

The seven-year program runs up to a max 105,000km.

Servicing intervals are more in line with a fuel-based car at every 12 months or 15,000km, whichever occurs first.

Mercedes offers a five year and unlimited kilometre warranty, with five years of roadside assist. The high-voltage battery components are also covered by a separate and industry-standard eight-year and 160,000km warranty.

Service intervals are once every 12 months or 25,000km and the service plan costs an average of $440 a year for the life of the warranty which is expensive for an EV, especially considering Polestar offers free servicing for the first five years, and Volvo’s electric offerings are around half the cost over the same period.
