Mercedes-Benz GLE-Class vs Kia EV9

What's the difference?

If you can get past the relatively steep asking price, the design appeals to you, and its slightly last-gen ergonomics work for you, then there’s a lot to like about the GLE. It’s a big, capable and comfortable cruiser, but given there are cheaper and more efficient options around, it would be a decision of the heart rather than the head.

Whether you think the EV9 GT is an over-priced mistake or the logical next step for a brand looking to move up in the world will depend on your point-of-view.

Kia has certainly extended the appeal of the EV9 range, but possibly in the wrong direction. Certainly the wrong direction if the goal is to add significantly more sales.

A cheaper alternative to the $97,000 EV9 Air would likely be a more popular choice from the point-of-view of Australian families considering replacing their diesel-powered SUVs with something that doesn’t rely on the chaotic fuel market. 

But that’s not really who the EV9 GT will appeal to. Instead, from the point-of-view of someone looking at a more expensive European option, whether it be an Audi Q8 e-tron, BMW iX or something else, the EV9 GT may be appealing in a very different way - assuming that they aren't driven by what badge is on the front.

Kia has certainly evolved beyond its ‘cheap and cheerful’ image or buying primarily for its long warranty. These days Kia is a mainstream brand, but whether it has enhanced its reputation enough to attract buyers willing to spend more than $130,000 will be decided in the showroom.

The GLE hasn’t changed massively since 2019, but sleeker lights and some tweaks around the face have helped it age relatively gracefully. As much as a 2.4-tonne SUV can be graceful.

There are still references to the original ML-Class the GLE succeeded, like the ‘coupe’ shape of the C-pillar that betrays the true SUV shape of the GLE.

The reshaped front-end has less black plastic on show, and its grille stays true to the pre-facelift design.

Inside, it’s just the steering wheel that’s new, everything else holds up well in terms of a design that’s also practical, though some would say it looks outdated given the many physical controls.

Surprisingly, given the price premium and flagship nature of the GT, there isn’t a lot to separate it from the slightly less expensive GT-Line.

It’s only when you look closer you notice subtle touches, like the ‘digital grille’, an illuminated section of the front of the car that extends the lighting signature when you start the car. The other obvious difference is the unique and huge set of 21-inch alloy wheels at each corner. The black design is offset by bright green brake calipers, which is a unique colour for the GT.

This signature fluro green colour is also on the seat trim, including contrasting stitching, as well as the GT badge on the (three-spoke) steering wheel that engages the most potent version of the electric motors.

The GLE is very easy to use because of those physical controls.

Save for the trackpad in the centre console that can be used like a laptop’s control mat - it’s a little fiddly - everything is easy to locate and adjust and the controls feel nice. The switches along the climate control row all feel nice and clicky, buttons in the centre console are big and obvious, and even the steering wheel’s haptic buttons are laid out sensibly.

The touchscreen’s software has been updated since launch during the facelift and it’s easy to navigate, but wireless Android Auto or Apple CarPlay are a good workaround.

The front seats, as well as being comfortable, are adjustable to an impressive degree for finding your driving position and there’s plenty of room and light to make the cockpit feel airy.

Storage isn’t at a premium, there’s plenty of space in door cards, the central storage bin, and the cupholders and phone charger can be hidden away.

Behind the front row, rear seat space is ample, though if you opt for seven seats the second row can be moved to accommodate a third row of passengers when needed.

In our test car, that isn’t the case, so the GLE’s cavernous 630 litres of boot storage is available. The second row can split 40/20/40, which is convenient for loading long items while four passengers are present.

Oh, but under the boot floor, despite some extra room for bits and pieces, no spare tyre. Big marks down for a car that absolutely has the space for one.

In terms of practicality, space and usability, the EV9 GT does a lot to justify its price tag, with a cabin the equal of anything the luxury brands offer, at least in terms of the level of equipment available.

The sporty seats have adjustable side bolsters to either hug you tight for dynamic driving or open up and let you get comfortable for relaxed commutes. The front seats are heated and ventilated and also include a two-way power adjustable leg rest, for even greater support.

Those in the second row are treated to two 'captains' chairs with heating and ventilation as well, plus a massage function and the leg rest, which creates a ‘business class’ vibe for the lucky passengers.

The second-row occupants also get sun blinds (albeit manual), separate air-conditioning controls and access to USB-C charging ports in the backs of the front seats.

Accommodation in the third row is a little tight, but if the second row compromises legroom slightly you’re able to fit six occupants in relative comfort.

Those in the front get their own sunroof but there’s a second, larger sunroof to bring light into the passenger section.

In terms of the multimedia system, it’s run through the twin 12.3-inch digital screens, which are housed in a single panel to create the impression it is one large display. This is the usual Kia system, which is very easy to navigate and has both Apple CarPlay and Android Auto integration, if you prefer. 

As a major plus, there are physical buttons for the climate control and a power/volume scroll wheel for the sound system. There’s also an on/off button for the car, which is a small feature but another welcome, user-friendly touch.

As for the boot, well, with all six seats in use there’s only 333 litres of space, which isn’t massive, but that’s why Kia sells the Carnival. For an SUV with seven occupants, 333L is alright.

If you only need five seats you can liberate a more generous 828L, which is really good. It’s a nice, roomy and open cargo space.

If you really need to carry a lot of stuff and not many people, you have 2393L with the second and third row seats stowed.

On top of this, there’s a small 52L frunk, which isn’t very big but it’s a good spot to stash the charging cable. Which oddly is not where Kia actually stores it, instead there is a small bag/box which is just velcroed to the boot floor.

Given the EV9 is a purpose-built electric vehicle, why is the charging cable not stored in a more integrated manner? It’s only a small detail, and Kia isn’t alone in doing this, but I still find it odd that carmakers haven’t found a better way to deal with the EV cable yet, especially when the frunk makes so much sense as a permanent storage spot.

Starting at $129,250 before on-road costs, the EV9 GT is the most expensive model Kia has ever offered in Australia.

Whether by accident or design it takes Kia into uncharted territory and legitimately has the brand competing with European alternatives. For example, the Volvo EX90 (from $124,990) is cheaper, as is a Polestar 3 (from $118,420) while the Audi Q8 e-tron (from $140,090) and BMW iX (from $142,900) are within $15,000.

That means that, perhaps for the first time ever, Kia will be cross-shopped against Europe's finest. Does it live up to that expectation?

Well, to help justify the price, the EV9 GT gets a more powerful motor, electronically controlled suspension and is loaded with technology and creature comforts inside.

This includes a standard six-seat layout, a 14-speaker Meridian Premium sound system, Kia Connect Telematics, in-built satellite navigation with 10 years of live traffic information and map updates, wireless phone charging and ambient mood lighting. But there is much, much more, as we’ll detail throughout the review.

So if you’re looking for an affordable EV to help take some financial pressure off, unless you’re stepping down from something European and very expensive, this won’t likely help.

But, if you’re looking for an upgrade in that $130k-$150k price range, and are ‘badge agnostic’ for that price, then maybe the EV9 GT is right for you. 

But no matter which way you look at it, this is an expensive Kia and it will be a real test for how far it has come if it can find buyers willing to spend this much on the brand once famous for cars $100,000 cheaper.

The GLE 450d’s 3.0-litre inline six-cylinder diesel engine is turbocharged, with a healthy 270kW and a brawny 750Nm to its name. That torque peaks all the way from 1350rpm to 2800rpm, by the way. Handy.

A nine-speed automatic transmission sends drive to all four wheels ('4Matic' in Merc-talk), while a 48-volt ‘mild-hybrid' system ('EQ Boost' in Merc-talk) means take-offs and shifts are aided by a bit of electric power.

Mercedes says the GLE can dispatch the 0-100km/h sprint in just 5.6 seconds, and that feels about right.

What’s under the bonnet, well technically underneath the front and back of the SUV, is what really separates the GT from the rest of the EV9 range.

The GT gets more powerful motors, boosting performance to 374kW of power and 740Nm of torque, which is a 92kW and 40Nm upgrade over the EV9 GT-Line.

Kia claims the GT can sprint 0-100km/h in just 4.5 seconds, nearly a full second faster than the GT-Line, and will keep going all the way to 220km/h. That’s really fast for such a big SUV, some might even say unnecessarily fast for a family-focused SUV, but given the asking price, adding extra performance is a logical move.

Mercedes claims a 7.4L/100km combined cycle (urban/extra-urban) fuel consumption figure for the big lug, but achieving that and making the most of its large 85-litre tank is a challenge.

We averaged 8.7L/100km on test but the trip computer showed as low as 8.0L/100km at one point. Get the GLE on the highway and fuel use plummets.

Theoretically you should be able to get about 1150km from a single tank, but realistically we wouldn’t plan trips any longer than 900km between fuel stations. 

Still impressive, given that’s about the distance between Melbourne and Sydney, or Sydney and Brisbane. Roughly.

The GT gets the same 99.8kWh battery as the GT-Line, but Kia claims the new flagship has a slightly longer driving range, but only 510km compared to 505km.

In the real world, the car’s own trip computer read around 480km when we collected it, but suggested with maximum efficiency (air-con off, driven in Eco mode, etc) we could reach more than 500km.

Energy consumption is rated 21.7kWh, but the EV9 GT was showing 24.2kWh on the trip computer. 

According to Kia, it can take up to 350kW of DC fast charging, which means a theoretical charging time from 10-80 per cent of just 24 minutes. Using a 50kW charger will extend that time to 83 minutes.

Again, in the real-world, using an Evie public charger we were able to add 42.1kWh in just under 34 minutes on a 75kW charger, taking the battery from 40 to 77 per cent.

A trip in the GLE feels like a welcome step back in time. Sure, coming in close to five metres long and two-and-a-half tonnes means it’s not a nimble steer, but the GLE strikes a nice balance of comfort and tactility that’s getting rarer.

None of it feels particularly sharp in terms of inputs or feedback, but it’s easy and predictable to a point where even winding back-roads are effortless to flow through.

The big diesel engine feels almost lazy, but it’s just so effortless in getting things moving as it strives to sit close to idle whenever possible. Because of that, there’s little noise from the engine bay even under reasonable acceleration, and the powertrain is helped by that 48-volt system which makes stop-starts from the lights super-smooth.

The mild-hybrid also helps smooth out power delivery, to the point where the only time the GLE feels clunky is the occasional lag when shifting from Drive to Reverse or vice versa.

The test car’s suspension isn’t the optional airbag set-up, but the non-adaptive steel does fine in terms of comfort and soaking up harsh surfaces. And even the big 21-inch wheels aren’t too bad over sharp bumps.

With smaller wheels (more tyre cushioning) and the air suspension, it feels like the GLE would ride gorgeously.

Its body control is predictable on smooth roads, and if you’re careful you steer the hefty SUV through tight, winding roads easily, but consistently rough surfaces can make the GLE feel unsettled for a short period of time.

There’s an overall softness to it that means gentle off-roading is possible, and the tyres are thick enough to make it comfortable. You won’t find yourself being tossed around on a flat enough gravel road.

On paper the EV9 GT sounds great if you’re into performance - 374kW and 740Nm is a lot for any type of car, even a big SUV. There’s no questioning that the EV9 GT is very, very fast, with that near-instant surge forward when you squeeze the accelerator in ‘GT’ mode.

But it is probably worth questioning the value of such a powerful and fast electric SUV, given the EV9 is clearly focused on being family friendly rather than a track weapon. To be perfectly candid, I rarely used the ‘GT’ mode because it just doesn’t suit the vast majority of driving conditions you’ll find yourself in driving an electric SUV.

I mean, you’ll never have an excuse for dropping the kids off at school late, but you’ll also likely rarely find yourself in a situation where you need to launch 0-100km/h in 4.5 seconds too. Obviously the performance is nice to have and helps to justify the asking price, but in day-to-day driving it doesn’t really make a significant difference to the EV9 experience.

Because, when you don’t unleash all that performance, you find yourself in a very quiet and refined SUV. The cabin is well insulated from the outside world, so you do get a sense of luxury, which is a major positive.

The electronically controlled suspension does a nice job of providing a comfortable and relaxed ride even on the big 21-inch alloys. It also does a good job, most of the time, of hiding the weight of such a big, electric SUV, so the chassis and suspension development team have done a great job.

The digital mirrors were also helpful during this test. The first time I tested an EV9 with them I found them a bit odd to use, as the angle you’re looking at on the screen isn’t the actual perspective of the situation. But this time around I quickly adapted to them and can see the merits of such technology.

The EV9 GT has everything Kia can include from a safety perspective. That includes airbag coverage for all three rows (including a centre airbag between the front passengers), ISOFIX and top tethers for all four rear seats and Matrix LED intelligent front lights. 

There’s also all the usual active safety systems, including autonomous emergency braking, lane keeping assist, safe exit warning, intelligent speed limit assist, driver attention warning, blind spot monitoring and 'Highway Drive Assist 2 with Lane Change Assist'.

That latter system, the ‘Drive Assist’ is good in theory, but Kia, like parent company Hyundai, still has some work to do on better calibrating and integrating some of these active safety elements. Yes, it’s great they have added the ability to mute the annoying speed limit sign recognition chime, but the Highway Drive Assist is still too jerky and adds a lot of unnatural weighting to the steering that makes freeway driving require more attention at times, rather than relieving the pressure on the driver.

This isn’t something specific to the EV9 either, it’s pretty typical across both the Kia and Hyundai range. While these systems are difficult to get right, it can be done, so a bit more work is needed to make it feel more seamless.

But overall, the EV9 GT comes loaded with all the safety equipment, both passive and active, that you should demand from a family-focused SUV, so credit to Kia for that.

Servicing isn’t cheap at Mercedes, even in the context of this market segment. A three-year service plan for the GLE costs $4045, while five years is $8055. That’s $1348 or $1611 per service respectively. The later services in those five years will of course be much more expensive and bring the average up.

Intervals are every 12 months or 25,000km, but Mercedes’ five-year/unlimited-kilometre warranty means anything major that goes wrong in that time should be covered - always read the fine print.

The brand’s Australian website lists 67 Mercedes-Benz dealers that can service your car.

The EV9 is covered by the usual seven-year, unlimited kilometre warranty, albeit with the battery only covered for seven years/150,000km.

Service internals are 12 months or 15,000km, whichever comes first, and Kia offers pre-paid servicing plans from three to seven years. The three year plan will set you back $723, five years $1379 and seven years $2038.

That means the average cost actually increases the longer you’re covered, but even over seven years your yearly average is only $291 in maintenance.

One major positive for the brand’s owners is Kia has grown to 147 dealers nationally, with coverage across both metro and urban areas, with all service centres able to work on EVs. That means you’ll get the same ease-of-service whether you buy a petrol, diesel or electric Kia.
