Kia Ev3 vs Mercedes-Benz EQB

What's the difference?

The GT-Line is relatively expensive, yes. The Air Standard Range isn’t groundbreaking even at under $50,000, no. But the sweet spot in the EV3 line-up is being able to pay $53,315 for the Air Long Range and come away with a roomy small SUV that can realistically cover almost 600km in the real world.

And it does everything properly, no big red flags or dealbreakers.

Its steering weight at speed on winding roads being the biggest complaint isn’t the end of the world for how otherwise comfortable the EV3 feels on-road.

Put it this way - I recently spent a few days in a Mini Aceman, a five-door electric SUV not too far from the EV3 in size. It is about as fast, and costs a little more, but it doesn’t have a lot more to offer in terms of features and it’s nowhere near as good on range with about 400km to its longer-ranged versions.

The EV3 might still have a bit of ‘sensible’ about it compared to some other electric small SUVS, but when it looks this cute and can get you an extra round trip out of the city compared to ‘Euro’ brands at the same price, it’s hard not to be impressed.

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

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.

Family resemblance is everything for Kia’s electric models, and the baby of the bunch so far definitely has lineage on show.

That’s a very good thing for the EV3, because as good as its specs are on paper, the way it looks is key to showroom (or on-road) appeal when it comes to convincing potential buyers.

At the same time as being seemingly made of sharp, angular elements, the EV3’s overall silhouette is relatively soft. Unfortunately, that means Kia’s ‘design philosophy’ (usually a relatively meaningless marketing line) is actually bang-on: Opposites United.

Inside and out, the EV3 is a direct descendant of the brand’s halo EV9 large SUV, and even in base Air specification looks like a properly premium small SUV.

Its narrow LED headlights and taillights were the stuff of Lamborghini concept cars just a few years ago, and its unique wheel designs and the use of contrasting coloured trim can impose either a modern, techy vibe or a bark-over-bite sporty image.

More marketing terms come out in the EV3’s face: Kia Star Map lighting and Tiger Face, respectively the way its lights seem to link ‘points’ together like a constellation map and the grille somewhat resembling a tiger’s nose.

There’s practicality in the design even from the outside - the gentle roof slope is only very slight to avoid eating into interior space, though it’s not the only way the car shrinks at the rear. The front track between the wheels is actually wider than at the rear, so the car is not only shorter but also narrower at the rear. It’s the first time Kia has ever implemented this ‘teardrop’ effect into a car, with the intention being to improve its aerodynamic efficiency.

Most of the colour schemes are decidedly subtle, the new Matcha Green hue looks better in person than can be captured on camera for example, but a new Teracotta colour is an earthy red that really stands out - I’m not sure it suits the car, personally.

In terms of colours inside, it's fairly muted and greyscale, but the mid-spec Earth comes with optional orange interior contrast trim that we weren’t sure would be available in the Australian market.

To invoke a cliche, the interior layout has the vibe of something you might imagine a spaceship cockpit looks like if you were a kid, but it doesn’t sacrifice any practicality by doing so. There are real buttons and switches visible, but only a few as the big screens dominate the driver’s side of the front row.

The look is helped by a series of recycled and “sustainable materials” including recycled PET and bio-based polyurethane. Kia’s aim is to “phase out the use of leather and continuously increase the use of bio-based materials”, so even the GT-Line doesn’t have real leather in it.

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.

Along with its general design, the EV3 also has the same focus on space efficiency as the much larger EV5 medium SUV and EV9 large SUV.

Kia compared the EV3 to the BYD Atto 3 and Volvo EX30 upon its global launch in Korea, and it’s stuck with the same comparison as it launches here.

In many exterior dimensions, the EV3 is smaller than the Atto 3, a medium SUV by sales category, while it’s larger than the EX30 in almost every way. However, interior dimensions are reported by Kia as being bigger than both cars in most aspects aside from the first row legroom, but even there only by about 10mm.

The EV3 is 4300mm long, 1850mm wide and 1560mm tall, and has a 2680mm wheelbase, but inside does feel like it’s a category upwards in terms of space.

Along with the roomy interior dimensions, there are plenty of handy spots to put things - a big central storage area and a higher one under the armrest, the device charger, door bottle holders - these and all the controls are generally within reach. 

The GT-Line loses a little bit of this storage space by turning the spot under the central armrest into a sliding table, which could be useful sometimes, but doesn’t seem to me as helpful as another place to put a drink, a wallet, keys, an avocado or whatever other trinkets you and your passengers may have.

The huge multimedia and driver display setup consists of two 12.3-inch screens and a 5.0-inch climate control screen in the middle. The centre climate screen is a little hidden by the steering wheel, but there are also physical climate controls also in the centre under the screen, so there’s nothing vital you can’t do in the EV3 easily.

There are also shortcuts to the main functions of the menu like navigation and media, Kia says tactile controls like that are important for keeping the car usable for a broad range of people.

In the second row, the EV3 feels pretty well suited to four adults for a reasonable trip - I’m 178cm and can sit behind my own seating position comfortably, though if I was too much taller my knees might rest on the hard plastic seat-back.

There is an armrest, places in the doors to put water bottles, and two USB-C plugs actually fitted into the seats. There’s also a little slot to put a phone that might be charging, though it could easily (and perhaps more usefully) fit other things instead.

Behind the second row is a generous 460L boot which puts other electric small SUVs to shame - the EX30’s is 318L and even the Atto 3’s is 440L. The EV3’s boot space extends to 1250L with the seats folded down.

The EV3’s boot floor can also drop down to accommodate taller items, plus there’s a 25-litre ‘frunk’ or under-bonnet storage space.

There’s no spare space-saver tyre, however, as is becoming disappointingly common.

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.

All three versions of the EV3 have the same drivetrain, the only difference being the smaller battery in the Air Standard Range.

The EV3 is front-wheel drive only, with a single motor at the front wheels putting out 150kW and 283Nm.

Differing weights between variants result in different 0-100km/h times, the quickest being the entry-grade Air Standard Range at 7.5 seconds, likely thanks to a smaller and lighter battery.

The Air Long Range takes 7.7 seconds, while the Earth and GT-Line both take 7.9 seconds.

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.

There are two battery sizes for the EV3, the 58.3kWh unit for the Air Standard Range and the 81.4kWh battery each of the Long Range variants is equipped with.

Of course, the Air Standard Range has the shortest electric driving range - 436km under WLTP testing. Its power consumption is a claimed 14.9kWh/100km.

The Air Long Range is the variant with the furthest electric driving range of the bunch, at 604km, as well as the same power consumption as the Standard Range at 14.9kWh/100km.

The Earth and GT-Line both wear the same set of figures, albeit lower distances and higher consumption than their more affordable counterparts. With 563km of electric range and 16.2kWh/100km consumption figures, they’re still able to cover very usable distances for real-world use.

Charging is the same across the line-up, with the supplied Type 2 AC charger working at a maximum 6.9kW on single phase or 10.5kW on three-phase power, and taking five hours and 20 minutes for Standard Range variants, or seven hours and 15 minutes for a Long Range from 10 per cent to 100 per cent.

On DC fast charging, with a CCS Type 2 charger, the EV3 charges as quickly as 29 minutes from 10 to 80 per cent in Standard Range, or 31 minutes in Long Range, when using a 350kW fast charger.

While we didn’t get a chance to properly run down the battery and test the EV3’s range, the drive route was relatively demanding with power consumption yet the EV3’s range didn’t plummet like you might expect on fast, steep and winding roads.

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 EV3’s arrival on Australian roads is not only important because it means we can test it in right-hand drive, but also because it’s had a localised ride and handling tune. Time for the proper judgement.

Kia Australia's local program lead for this is, as it has been for years, Graeme Gambold, and according to the brand he aimed for neutral balance with confidence-inspiring and responsive handling, and a linear, natural steering feel. And it’s pretty close to nailing all of that.

In town and on backroads, its ability to soak up bumps and handle rough surfaces is impressive. Not a lot of noise comes into the cabin in either case, too, a feat given the road surfaces. In fact, even with the radio off, the EV3 feels pretty well insulated from the outside, including wind noise.

It's cornering and handling is nice and predictable. It feels designed to be safe if you misjudge a corner, only gently understeering when you've come in a bit spicy.

The body doesn't roll or pitch dramatically, so the car feels planted and, as intended, flat through the bends.

But there’s one aspect to the tune in which the EV3 feels like it could do with a little more attention - its steering.

At low speeds, the steering is light enough, but at higher speed it feels a little heavy. I’m not sure if Gambold’s been going to the gym or if it’s that I haven’t really, but it feels like there’s some unnecessary resistance, regardless of drive mode or camber on the road, requiring a bit more input on the wheel than you'd like.

It does let the car down in terms of driving out on country roads, but fortunately it's not a dealbreaker on highways or in its intended city or suburban environments.

Otherwise, the EV3 is extremely pleasant, with its outputs and delivery feel about right for a small electric SUV, never feeling too slow or unruly. It doesn’t spin its wheels with too much torque, even on wet roads and when hustling out of a corner.

The paddles which allow you to adjust the intensity of the regenerative braking also mean you barely need to use the left pedal, which is a plus for increasing the available driving range.

Speaking of the left pedal, a sudden stop thanks to a surprise slow car around a blind corner went smoothly thanks to a decent set of brakes.

In all, the car is ergonomically sound from the drivers seat, with the positioning for the seat and steering wheel feeling comfortable and easy to adjust, though slightly better vision out the rear sides would be good.

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.

Kia’s seven-year, unlimited-kilometre warranty applies to the EV3, and though that was once industry-leading, it’s now being matched or overtaken by many rivals.

Roadside assistance is covered for one year but can be extended to up to eight years if serviced with an authorised Kia dealer.

Kia also backs the high-voltage equipment in the car with a more specific seven-year or 150,000km warranty, whichever comes first.

Australian servicing costs are pretty minimal in the EV3, with Kia offering well-priced pre-paid plans of three ($674), five ($1285) or seven years ($1897). Certainly some points for Kia on that one.

Service intervals are on the shorter side for an EV, at every 12 months or 15,000km, whichever comes 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.
