Mercedes-Benz GLC-Class vs Kia EV9

What's the difference?

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

The Kia EV9 GT-Line earns some serious family points with its practical and luxuriously appointed cabin. Each row enjoys ample amenities and space and you can’t discount the ability to fit five child seats!

That’s where similarities with its Carnival sibling end because the driving performance is too mixed for my liking. Some of its safety features don’t react well in real-world situations but if you’re looking for an electric car that will fit a big family, this ticks that box.

My son thinks the EV9 is really cool with the ambient lighting and two sun roofs. He also loves having his own climate control and sun-blinds, so he gives it a 10/10.

The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

To be frank, the EV9 resembles a Lego car on steroids, but it turns heads. I’ve had more looky-loos peeking into the windows this week than any other car I’ve driven.

Once you get over the (very) square shape, there are some awesome design aspects to be had.

Like the flagship exclusive Matrix LED headlights and 'Ocean Blue Matte' paintwork that feels velvet-like under your hands. The black 21-inch alloy wheels and their aerodynamic covers look futuristic and cool.

The pronounced nose looks wide-set because of the positioning of the tall headlights separated by a strangely blank panel in the middle.

In fact, the whole exterior incorporates a slew of blank panels which reinforce the square look.

The flush auto door handles, big windows and dark roof give some cool-kid cred. The digital side mirrors are not for everyone but as a driver, you get used to them. The tech looks as though it's come straight out of sci-fi movie!

The interior is downright plush with the premium-looking upholstery and customisable 64-colour ambient lighting.

The dashboard has floating panels which create a cool 3D effect and even the badge on the steering wheel is illuminated.

There is a plethora of soft touchpoints throughout and the black headliner helps make the cavernous cabin feel almost cosy.

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

It’s large and you have ample space throughout the car. Even third rowers don’t miss out.

It feels quite van-like with the high seat positioning and extending centre console but you get a great view out of the massive windows.

The electrically-adjustable front seats are very comfortable but the mesh ergonomic headrests are a little too comfy!

The boxy steering wheel is nice to use but cut into my vision of the climate control screen from my driving position. I felt like I was looking around it a lot.

Individual storage is fantastic in all three rows. Up front you get a little pocket in the armrest and a huge shelf underneath the centre console.

The glove box is large, but curiously, has a small aperture. There are retractable cupholders in the centre console utility tray and drink bottle holders in each door.

The middle row has two drink bottle holders, four cupholders, two map pockets and a deep but narrow storage cubby at the back of the centre console.

Third rowers are not forgotten, either, with four cupholders and directional air vents to enjoy.

Amenities are great throughout the car and my son loves having the retractable sun-blinds and his own climate control in the middle row. It’s also an easy car to get in and out of, which we both enjoy!

The middle row's 60/40 split is a practical touch and they can be shifted manually or electrically with a one-touch button for access to the third row.

Speaking of which, there is an okay amount of room for my 168cm (5'6") height in the third row (if you push the middle row forward a smidge). And it doesn’t feel claustrophobic thanks to the wide windows.

If you have a pile of kids to shove in this car, you’ll be happy that this row also features two ISOFIX child seat mounts and two top tethers.

I wouldn’t want to be climbing into the third row to buckle in a kid, so reserve these seats for older kids.

The technology looks good but is simple to use which is always a good combination. There are plenty of charging options to choose from with each row getting two USB-C ports, while the front also enjoys a 12-volt socket and a wireless charging pad.

The touchscreen multimedia system is responsive and easy enough to use but the controls on this panel can be difficult to see and use. They’re not always responsive.

I like the satellite navigation and the way the head-up display pulls through the directions. There’s wired Apple CarPlay and Android Auto, too.

The digital instrument cluster is mildly customisable and easy to read. There is a little control panel on the driver’s door which houses the buttons for most of the added seat functions. But it’s hard to read as all the buttons are almost identical.

The boot is a good size when all seats are in use at 333L, which is plenty for my day-to-day errands, but pop the third row down and that jumps up to 828L.

Not as big as you might expect in a car of this size but that’s the compromise of going electric. The batteries have to go somewhere.

You do get a 52L frunk at the front, for cable storage. The loading space is level and you only get a tyre repair kit rather than a physical spare but it’s handy having the powered tailgate.

There are three variants for the EV9 and our test vehicle is the flagship GT-Line model that will cost you $121,000, before on road costs. That makes it the most expensive Kia to date, with the top-spec Carnival Platinum diesel only costing $67,580 (MSRP).

However, it’s nearest rival, the Mercedes EQS450 SUV, sits at $194,900 making the EV9 look downright cheap with the $73,900 price difference.

Yes, you could argue the badges would always offer a little price difference but Kia has made a true flagship model in the GT-Line because it is stupidly well-specified. It’s almost a case of what doesn’t it come with!

In terms of luxury appointments, occupants enjoy two sunroofs and two-toned synthetic leather upholstery. The electric front seats feature heat and ventilation functions, adjustable lumbar support and the driver gets a massage function.

The front seats have a relaxation mode, which I liken to the reclining seats in business class (someone send me on a trip to confirm!).

If you recline, add the sounds of nature feature and pop on the massage function, it’s like you’re in a day spa. Delightful.

The middle row outboard seats are also heated and ventilated which adds a lot of comfort and there’s a heated steering wheel, too.

Other standard equipment includes 21-inch alloy wheels, flush door handles, digital side mirrors, privacy tinted rear glass, pixel matrix LED headlights, 14-speaker Meridian premium sound and remote parking assist.

Practical features include a powered tailgate, extendable sun visors, retractable sun-blinds and three-zone climate control.

The technology is upmarket with dual 12.3-inch digital screens covering instrumentation and multimedia. There's also a 5.0-inch ‘quick-look’ climate control panel. A full tech run-down will come later.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

The EV9 GT-Line is a pure-electric AWD with dual motors, one located at each end of the car, producing a maximum power output of 283kW and 700Nm of torque. It has a lithium-ion battery with a big capacity of 99.8kWh.

Overall, the EV9 GT-Line is powerful and capable of sprinting from 0-100km/h in just 5.3 seconds. That’s impressive for such a heavy car with a 2500kg (braked) towing capacity.

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

It's a hulk of a thing to have to move around and the motors perform brilliantly, but my energy cycle figure surprisingly came out at only 21.4kWh, after mostly open-road driving.

The official combined energy cycle is 22.8kWh, so that's a solid result.

The driving range is up to 505km, which takes the sting out of any range anxiety.

The EV9 features a Type 2 CCS port as well as an 11kW AC charger and you can get from 10 to 100 per cent in just over nine hours.

On a 50kW DC charger, you’d see that time drop to just 83 minutes to get from 10 to 80 per cent and it will shrink to 24-minutes on a 350kW charger.

A cool feature is the vehicle-to-load capability, so you can charge and/or power larger appliances on the go. Hello camping!

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

Strangely for a large SUV, this car feels most at home in an urban environment. It’s in the city where it feels nimble and easy to manoeuvre. Zippy even, and you don’t notice it’s size.

But it’s a different story on the open road. 

At higher speeds there is a lot of movement in the body and thanks to its floaty suspension the amount of roll in corners starts to make it feel cumbersome.

It has the power to handle mountain driving or overtaking, but remains a bit unsure of itself in these situations.

The steering is responsive and concise, which makes for a nice driving experience in the city and navigating a car park.

The cabin gets very little noise thanks in part to sound-absorbing acoustic glass and foam in the tyres. It makes for a fairly pleasant journey overall.

As a passenger, though, I began to suffer motion sickness thanks to the digital side mirrors! Not an issue when I’m driving, but even my husband, who has an iron stomach, commented on how distracting they are.

It’s nice having a column shifter, as it helps open up the storage in the centre console but it can make pressing the push-start button a bit awkward.

The EV9 has a decent 12.4m turning circle and is relatively easy to park. The 360-degree view camera system is clear and I love having the front and rear parking sensors on this big boy.

But to access the front camera, you have to be in Drive. You can’t select it on the touchscreen, which is a pain when you’re manoeuvring into a tight space.

If you’re not confident, the EV9 also features an updated park itself feature which means you can park it remotely from your key fob. 

The EV9 has an extensive safety list and the blind-spot view monitor, which pops a video feed of your blind spot onto your dash, is a stand-out feature.

Standard safety items include blind-spot monitoring, lane departure alert, daytime running lights, forward collision warning, side collision warning, rear-cross collision warning, rear cross-traffic alert, intelligent seatbelt reminders, a 360-degree view camera system, as well as front and rear parking sensors.

There are other items but I need to call out their sensitivity issues.  

The driver attention monitor doesn’t always activate when you have sunglasses on and alerts you via multiple warning sounds and alerts on the instrument cluster.

The lane keeping aid is rather aggressive, which makes for a jerky on-road experience, and the adaptive cruise control with stop/go functionality isn’t nice to use.

Even on the shorter distance setting, it slows down way too fast when approaching a car in front.

Also, annoyingly, this model features all the warning chimes and alerts that are linked to the traffic sign recognition tech.

Go over the speed limit by one kay, chime. Enter a school zone, several chimes. If the speed sign changes, chime. If the traffic sign changes, you guessed it, CHIME.

Suffice it to say I don’t like this feature.

There's an option in the car set-up menu that turns off the warning sounds but keeps the important sign information. However, it's not permanent and has to be selected every time you turn on the car.

In better news, the Kia EV9 has just been awarded a maximum five-star ANCAP safety rating and features nine airbags which includes curtain airbags covering all three rows and side chest airbags for the second row.

Usually, you only see side chest airbags on the front row, so this is great! It also sports a front centre airbag to protect the front row from head clash injuries.

The EV9 has autonomous emergency braking with car, pedestrian and cyclist detection as well as junction turning assist.

It's operational from 10 to 80km/h but surprisingly, the car-to-car avoidance is only operational from 10 to 60km/h.

That upper speed figure usually sits closer to 160km/h. Unless there is a typo on ANCAPs website…

Families will rejoice that there is a total of four ISOFIX child seat mounts (two in the middle row and two in the third row) plus a total of five top-tether anchor points.

The car is large enough to accommodate five child seats and there’s plenty of room for front passengers when a 0-4 rearward facing child seat is installed on the middle row.  It’s pretty much a people mover at this point!

The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.

The EV9 comes with a seven-year/unlimited km warranty, while its battery is covered for seven years, 160,000km. It’s normal to see an eight-year battery warranty term for EVs, though.

You can pre-purchase a three-, five-, or seven-year servicing plan, priced at $706, $1351 and $1997, respectively.

The seven-year schedule costs an average of $285 per service, which is good, but servicing intervals are more in line with a fuel-based car at every 12 months or 15,000km, whichever occurs first.
