Genesis GV80 vs Mercedes-Benz GLC-Class

What's the difference?

The Genesis GV80 Coupe is a rare breed – it comes packed to the gills with features, has great ownership benefits and can easily accommodate a large family in comfort.

The fuel economy isn’t great but it looks and acts the part of a true luxury SUV. My husband and son were impressed and enjoyed all of the features it has.

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.

At first glance, there’s not a lot that separates the external styling of the Coupe and SUV, at least in the front.

The biggest difference is obviously in the rear and it's here Coupe's design shines. The SUV sibling looks nice but is a little boxy at the rear and features a dicky-looking window. The Coupe's rear is pinched but it’s rather softly done compared to some rivals.

It manages to look sleek and sexy as coupes tend to be without losing any of its large road-side presence.

The 'Storr Green Matte' paintwork on our test car highlights the high-end feel, as does the huge LED external lights and chrome accents.

Head into the cabin and you'll find design elements which accentuate the width of the car – like the long air vent strip that runs the length of the dashboard, a wide centre console and the huge 27-inch OLED technology screen that houses the media system and instrument cluster. Even the touchscreen control panel for climate and seat functions is big.

Our test model has a cream-coloured suede headliner and quilted Nappa leather seats that look plush. Contrasting stitching and the seatbelts are a bright red (or dark orange, depending on who you ask) and the panoramic sunroof adds a bright and cheery element.

The ambient lighting surrounds a lot of the features, like the cupholders and the crystal rotary dials. In fact, when you pop the car into reverse, the light changes from whatever it was to red, which is neat.

As far as luxury cars go, this totally looks the part and while design is very subjective, I love how this looks inside and out. Let us know what you think of it in the comments.

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.

With all of its features offering comfort and luxury, practicality is pretty high for the GV80 Coupe.

The cabin feels almost cavernous up front for my 168cm height. As mentioned, the seats are very comfortable and there is a stretching function that briefly comes on during a longer journey to ease any fatigue in your lumbar.

The rear row is almost as large as the front and there's a limo-like quality to the legroom that taller individuals will enjoy. The headroom is good for the outboard seats but a taller adult will be hunched when sat in the middle. Keep that for a kid!

Amenities in this row are excellent with the powered outboard seats that feature heat and cooling functions, directional air-vents, climate control and retractable sun-blinds (my son's favourites). 

The individual storage is a little less than you might expect for such a large car, especially up front, as all options are on the shallow/small side.

There is a middle console (think of it as a tray), glove box, two cupholders, two drink bottle holders and a phone cubby that can be closed to keep things looking neat.

The rear row sees two map pockets, two cupholders and a storage cubby in the fold-down armrest, as well as some shallow bin storage.

Technology looks stellar, is easy to use and found throughout.

You're spoiled for choice when it comes to charging as there are four USB-C ports, three 12-volt sockets and a wireless charging pad to choose from. 

And new for 2025 is the UV-C feature, which sterilises whatever you place inside the middle console. Handy for anyone who wants to disinfect small items, like a phone, keys or wallet.

The multimedia system takes a while to get used to as the tech has been updated but once you do, it’s an easy system. You can access the media system via the touchscreen or the rotary dial. Climate control and seat functions are accessed via the large control panel that sits underneath, which is handy for when you're on the go. 

The GV80 Coupe has built-in sat nav, wired Apple CarPlay and Android Auto, as well as, a 12-inch colour head-up display.

Because of the sleek rear shape, the boot space sits at 644L when all seats are in use. It’s large enough for my gear and weekly errands and I like the powered tailgate's proximity feature. As long as you have the key fob, it will open when you stand at the rear. Great for when you have your hands full.

The loading space is level and the rear seat has a 40/20/40 split, which opens up storage options. But underneath the floor, there are heaps of cubbies for extra storage of smaller items and it’s here the tyre mobility and roadside assistance kits are housed.

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.

The power and torque figures aren’t the only numbers that have risen sharply, with the GLC63 clearly impacted by a double whammy of inflation and the usual new-car price rise.

The GLC63 now starts at more than $191,814 for the SUV and $198,415 for the Coupe, which represents a nearly $30k increase over the old V8-powered model, which was priced at $164,600 just two years ago. Even for luxury car buyers that’s a big jump, especially when you’re trying to convince people of the merits of the four-cylinder powertrain. 

That also means it's more expensive than all of its key competitors, including the BMW X3 M Competition, Maserati’s Grecale and the outgoing, petrol-powered Porsche Macan GTS.

To help explain some of this price increase Mercedes-Benz Australia has opted for a high level of standard specification for local cars. Standard equipment includes 21-inch alloys, AMG composite braking, a panoramic sliding sunroof, a unique AMG steering wheel, power-adjustable sports seats in Nappa leather, a head-up display, dual-zone climate control, wireless smartphone charging and a Burmester 3D Sound system.

Also included is the AMG Track Pace suite, for those who want to unleash their GLC on the racetrack.

There’s also a limited run, AMG Edition 1 Package available too, for an additional $12,900. On the outside you get Manufaktur graphite grey magno paint, foiling with colour gradation and large AMG logo on the sides, an AMG Aerodynamics Package, unique alloy wheels with Edition 1 and AMG branding, yellow brake calipers and an AMG fuel filler cap in silver chrome with AMG lettering. 

Inside there’s AMG Performance seats, AMG Nappa leather in black with yellow contrasting stitching, AMG illuminated door sills,  carbon-fibre AMG trim highlights, yellow seat belts and a unique AMG Performance steering wheel wrapped in carbon-fibre and microfibre.

The GV80 model facelift sees all variants enjoy a powerful 3.5L twin-turbo petrol V6 engine that produces 279kW of power and 530Nm of torque.

The Coupe is an AWD, features an eight-speed auto transmission and can do a 0-100km/h sprint in just 5.7 seconds.

It also has different terrain modes and a braked trailer towing capacity of 2722kg. Whether you’d use this car for that sort of stuff is another matter.

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.

Aye, here's the rub, as the hefty power comes with a thirsty gullet.

The official combined fuel-cycle consumption figure is a hefty 11.7L/100km and my real-world usage came out at 11.4L/100km after doing a lot of open-road trips this week.

I haven’t held back using the power but it's thirsty compared to its rivals which mostly sport mild-hybrid powertrains.

Based on the large 80L fuel tank and official combined fuel cycle consumption figure this car's theoretical driving range is 684km.

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.

The GV80 Coupe has a deep well of power to dip into and fantastic pick up. The power delivery feels effortless and it’s easy for urban and open-road driving.

The GV80 isn't as dynamic on the road as some of its rivals when it comes to the ‘sporty’ factor and you notice that the most when you hit high winds or tackle a tight turn, as there is some roll, but on the whole it’s a smooth ride. Think of it as more ‘stately’ than sporty.

The cabin is mostly quiet but wind noise can creep in at higher speeds.

The wide windows and high ride mean the visibility is very good and so is the sound quality from the 18-speaker Bang & Olufsen audio system. Every school run is a concert!

The GV80 Coupe is large car and will fill out a parking space but it’s not hard to park because the 360-degree view camera system is so good and the projected parking guidelines add assurance in a tight spot. 

There is a remote parking assist feature, where you can move the car remotely from your key fob, which is great for those times someone parks a bit too close and there’s not enough door clearance to get in.

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.

The GLC63 comes standard with a comprehensive suite of safety features including 'Distronic' (Mercedes’ name for adaptive cruise control), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Traffic Light Assist' and 'Adaptive Highbeam Assist'. It also includes Mercedes’ 'Pre-Safe' accident anticipation system - which pre-tensions the seat belts and will even play a white noise to protect your ears if it senses a crash is imminent.

A parking system that includes a 360-degree camera and active parking assist is also included.

The GLC range was awarded a five-star ANCAP rating in 2022, which pre-dates the latest testing protocols, so doesn’t provide a like-to-like comparison for vehicles tested after that date.

The GV80 Coupe comes with a five-year/unlimited km warranty and complimentary servicing for five-years or 50,000km, whichever occurs first.

There is also complimentary roadside assistance through Assist Australia for five years.

Since this is a turbo, the servicing intervals are a little annoying at every 12 months or 10,000km but it’s rare for a car brand, let alone a luxury one, to offer anything for free. What Genesis offers is a real plus.

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.
