Kia EV6 vs Mercedes-Benz GLB-Class

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.

It’s easy to say the GLB35 doesn’t deserve to be called an AMG when looking at its credentials on paper, but get behind the wheel and it’s evident Affalterbach played a key role in making it feel as special to drive as it should be.

The GLB35 has all of the great qualities of the GLB250 and other GLB variants, but successfully adds a performance focus to make for an even more compelling package.

Indeed, the GLB35 proves you can pretty much have it all.

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.

With the boxy and therefore rugged-looking GLB laying some great foundations, it’s no surprise the GLB35 looks pretty damn good – to these eyes, at least.

Being an AMG model, it stands out from the crowd with an aggressive body kit, with the chunky bumpers, aerodynamic roof spoiler and racy rear diffuser all unique alongside the now-signature Panamericana grille insert.

A set of 20-inch alloy wheels with 255/40 tyres ups the ante at the side, where the carryover black plastic wheel-arch and skirt cladding serves as an obligatory reminder that this is an SUV.

Also of note are the nicely designed LED headlights and tail-lights, which literally light the way, but there’s no getting past the bespoke diffuser element, which integrates the sports exhaust system’s dual 90mm tailpipes.

Inside, the GLB35 is a technological tour de force, with a pair of 10.25-inch high-resolution displays proudly sitting side by side atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes-Benz’s MBUX multimedia system, which arguably remains the best there is today thanks its speed and breadth of functionality and input methods.

The GLB35 is also properly premium. Lugano leather upholstery covers the seats and armrests, while Nappa trims the sports steering wheel. Even the door shoulders and inserts get ‘cow hide’, although theirs is of the artificial variety.

Soft-touch materials are used for the upper dashboard, leaving hard plastics to the lower sections, which is what you’d expect for the price.

While the black headliner makes for a dark cabin, brightness comes from the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let’s not forget the pop of colour provided by the addictive ambient lighting.

And mercifully, scratch- and fingerprint-hungry gloss-black accents are limited to the surrounds of the turbine-style front air vents, dual-zone climate controls and centre console.

Unique to the GLB35 are Carbon Structure trim and stainless-steel sports pedals, just in case you forgot you weren’t driving a regular GLB.

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.

Measuring 4650mm long (with a 2829mm wheelbase), 1845mm wide and 1660mm tall, the GLB35 is more like the GLC43 in size than the GLA35, making it a mid-size SUV despite its small underpinnings. And that is good news for practicality.

Cargo capacity with the 50/50 split-fold third row stowed is more than solid, at 565 litres (VDA), but it can be increased to a cavernous 1800L with the 40/20/40 split-fold middle bench also not in use. If six or seven passengers are onboard, though, there’s very little room to move.

Nonetheless, the boot is still well packaged, featuring a huge aperture, no load lip, and a flat floor, which make loading and unloading bulkier items a hell of a lot easier. And even the load cover can be stored underfloor when out of action. How good.

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet on hand to make matters even easier, while the rear seats can be stowed from the boot.

While we’re on the topic, Mercedes-Benz says the third row can accommodate passengers up to 168cm tall, with the middle bench able to slide fore and aft by up to 140mm.

Yes, I'm too tall, at 184cm, but I can still sit in the very back, although not in total comfort. All in all, about a centimetre of legroom and negligible headroom and toe-room are on offer there for me.

That said, getting in and out in the first place is the real challenge here, with the middle bench unable to tumble forward for easy ingress and egress. Yep, you’re not going to look smooth either way. Children can deal with it, but adults won’t be thrilled.

Therefore, the middle bench is the place to be, even when it’s slid all the way forward. Behind my driving position, it offers about a centimetre of legroom, but this can be increased to several inches by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an inch of headroom. The latter is more impressive when you consider that’s what you get with the standard dual-pane panoramic sunroof fitted.

Even better, the second row can seat three adults at a pinch, partly thanks to the low transmission tunnel, which means there’s the right amount of space for six fully grown feet across the two footwells. It goes without saying children will again be fine.

Speaking of which, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, which makes the GLB35 a serious option for families that like to be sporty.

There are plenty of in-cabin storage options, with the large central storage bin featuring a pair of USB-C ports, while the glovebox is also quite useful, even if it is oddly shaped. And there’s also a sunglasses holder in front of the rearview mirror.

The centre console’s cubby isn’t really designed for storage, with it basically taken up by two cupholders, another USB-C port and a wireless smartphone charger.

The front door bins can accommodate one small and two regular bottles each, which is great, while their rear counterparts can take one small and one regular apiece.

Second-row occupants also have access to a fold-down armrest with another pair of cupholders, but being of the retractable variety, they’re flimsy.

These passengers also have two USB-C ports, with the pair folding out below a small cubby and air vents, which are found at the back of the centre console. Storage nets are also fitted on the front seat backrests.

And don’t worry; the third row gets in on the action, with two cupholders (one regular, the other small) splitting the seats, which have individual USB-C ports and device straps to the sides.
 

Priced from $88,535 plus on-road costs, the GLC35 currently sits atop the GLB range, above both the $59,900 GLB200 and $73,535 GLB250.

Standard equipment not already mentioned in the GLB35 includes dusk-sensing lights, rain-sensing wipers, power-folding side mirrors, black roof rails, rear privacy glass and a power-operated tailgate.

Inside, satellite navigation with live traffic, Apple CarPlay and Android Auto support, digital radio, a 225W sound system with nine speakers, keyless entry and start, power-adjustable front comfort sports seats with heating and memory functionality, auto-dimming mirrors, illuminated ‘AMG’ scuff plates and ‘AMG’ floor mats feature.

As is commonplace for Mercedes-Benz models, the GLB35 has plenty of options with most expensive, so you could drive away with a vehicle that’s dearer than you originally thought.

But aside from a spare wheel and some safety equipment we’ll cover in a moment, the GLB35 doesn’t leave much to be desired, which is always a good thing.

Nonetheless, our test vehicle was finished in $1490 Iridium Silver Metallic paintwork, which is one of eight extra-cost exterior colour options.

As mentioned, the GLB250 is a unique proposition, so it’s only comparable rival, the more affordable but less sporty Land Rover Discovery Sport P250 HSE ($78,432).

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.

The GLB35 is powered by an uprated version of the GLB250’s 2.0-litre turbo-petrol four-cylinder petrol engine, with the AMG-fettled version producing a more substantial 225kW of power from 5800-6100rpm and 400Nm of torque from 3000-4000rpm (up from 165kW/350Nm).

This version is also matched to an eight-speed dual-clutch automatic transmission as well as Mercedes-AMG’s front-biased but fully variable 4Matic all-wheel-drive system.

Thanks to this combination, the GLB35 can sprint from 0-100km/h in just 5.2 seconds with launch control enabled, while its electronically limited top speed is 250km/h.

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.

The GLB35’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.3L per 100km, while its carbon dioxide emissions are 186 grams per km. All things considered, both claims are pretty decent.

In our real-world testing, though, we averaged a high 14.1L/100km over 75km of driving split between highways and country roads, so not your typical mix, then. A heavy right foot also played into that result, so expect a better return after a regular run.

For reference, the GLB35’s 60L fuel tank can be filled up with 98RON petrol at minimum.

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.

Don’t let the GLB35’s family friendliness fool you, this is an SUV that can get up and go.

The engine’s extra power and torque over the GLB250 are immediately felt behind the wheel, with the GLB35 accelerating with the vigour of an all-wheel-drive hot hatch, which makes sense given their similar claims.

And if you have one of the sportier drive modes engaged, the booming noise generated is also special – even if a lot of it is of the artificial variety, pumped into the cabin to make occupants feel like things are getting serious.

What is genuine, though, is the well-rounded transmission, which is characteristically quick with its upshifts. At the same time, it’s also relatively smooth, even at low speed, which has proven to be a challenge for dual-clutch units over time, but not here.

To earn the AMG badge, the GLB35 goes even further with other mechanical upgrades, including sports tunes for the suspension and steering.

Specifically, the GLB35’s independent suspension set-up not only consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers, but also introduces new steering knuckles, transverse control arms on the front axle, and a stiffened subframe.

The resulting ride is actually quite good. Yes, the extra firmness over the GLB250 is noticeable – particularly in the sportier drive modes that stiffen the adaptive dampers all the way – but it’s by no means a deal-breaker.

That said, it’s worth noting our test vehicle was fitted with the optional 21-inch alloy wheels ($1990), so the GLB35’s like to ride even better on its standard package.

This is remarkable considering the handling improvements made, with the GLB35 managing body roll and pitch better than the GLB250 when pushing hard into and around corners, coming out of which grip is plentiful thanks to the all-wheel-drive system.

Thankfully, the standard-fit high-performance braking package consisting of 350mm front and 330mm rear discs with four- and one-piston callipers respectively helped it wash speed away with ease when attacking the twisty stuff with intent, even with 1857kg (kerb) to deal with.

Also on hand is electric power steering, which is speed-sensitive and has a variable ratio in the GLB35. Basically, it’s quicker when you want it to be, remaining on the lighter side in hand until you engage one of the sportier drive modes and weight is increased markedly.

ANCAP awarded the GLB range its maximum five-star safety rating in 2019.

Advanced driver-assist systems in the GLB35 extend to autonomous emergency braking (AEB) with pedestrian and cyclist detection, lane-keep assist, blind-spot monitoring, rear cross-traffic alert, traffic sign recognition, driver attention alert, tyre pressure monitoring, hill-descent control, hill-start assist, park assist, a reversing camera and front and rear parking sensors.

Is anything missing? Well, steering assist, adaptive cruise control, active blind-spot monitoring and front cross-traffic alert form the optional Driving Assistance Package ($1990), which definitely should be standard at this price point.

And let’s not forget the two other noticeable absentees: surround-view cameras and high-beam assist. They’re annoyingly part of the optional Vision Package ($1190), which was fitted to our test vehicle.

Nonetheless, other standard safety equipment includes nine airbags (dual front, front-side, curtain and rear-side plus driver’s knee), anti-skid brakes (ABS), electronic brake-force distribution (EBD) and the usual electronic stability and traction control systems.

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.

As with all Mercedes-AMG models, the GLB35 comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

The GLB35’s service intervals are long, at every 12 months or 25,000km (whichever comes first). Better yet, it’s available with a three-year/75,000km capped-price servicing plan, but it costs $2750, with the third visit alone incurring a $1300 charge.
