Mercedes-Benz GLS vs Genesis GV80

What's the difference?

The GLS63 is an intimidating beast from afar, but it rewards its occupants in almost every way. Yep, there really isn’t a box it doesn’t tick without serious compromise, such is its breadth of capability.

If there was ever a Swiss Army Knife of cars, the GLS63 is definitely a contender for the title, one that makes it very hard to wipe the smile off your face. Just make sure you can fit it in your garage first…

I rarely drive luxury vehicles so it doesn’t take much to impress me. However, it’s clear to anyone with half a brain (even me) that the GV80 is a premium ride and in Black guise it’s even better, albeit by increments only and those perceived improvements largely hinge on styling tweaks to the Signature platform on which it’s based.

Does it tick all of the boxes that someone considering this type of vehicle would want ticked? Sure it does and then some. But there’s plenty of stiff competition in the form of other premium AWDs on the market nowadays and even some 4WD wagons that offer similar levels of prestige.

If the GLS63 was a Marvel superhero, it would undoubtedly be the Hulk. Simply put, it has road presence like few others. In fact, it’s frankly menacing.

Of course, the GLS is already pretty intimidating due to its sheer size and blocky design, but the GLS63’s full-fat AMG treatment takes it to another level.

Naturally, the GLS63 gets an aggressive body kit, with its purposeful bumpers, side skirts and rear spoiler serving as instant reminders of what you’re dealing with, but it’s AMG’s signature Panamericana grille insert that really hammers home the point.

Around the side, the GLS63’s 22-inch alloy wheels with staggered tyres (front: 275/50, rear: 315/45) make their presence known, positioned below the wheelarch extensions.

That said, some fun’s also had at the rear end, where the GLS63’s diffuser element integrates the foreboding sports exhaust system with quad tailpipes very neatly.

The focused Multibeam LED headlights also look the part, while the opposing LED tail-lights tie everything together outside quite nicely.

Inside, the GLS63 stands out from the GLS crowd with its sports steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are covered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

Of note, the doors bins are unfortunately of the hard plastic variety, which is very disappointing in a vehicle that costs this much. You would expect that cow hide would also been applied to them, but alas it isn’t.

The GLS63’s black headliner serves as an obligatory reminder of its sporting intent, and while it makes for a dark cabin, metallic accents are prominent throughout, while the optional trim (our test vehicle had carbon-fibre) mixes things up, alongside the ambient lighting.

And let’s not forget the GLS63 is still loaded with plenty of cutting-edge technology, including a pair of 12.3-inch displays, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes’ class-leading MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up arguably remains the best there is today thanks to its speed and breadth of functionality and input methods.

I most frequently test and review vehicles that are tall, bulky and have plenty of ground clearance – usually 4WDs – so the GV80 is, in my experience, a mild revelation.

Firstly, it’s low and sleek and practically oozes – yes, oozes – prestige. Word of warning here. If you don’t like black as a colour on your car you’re in the wrong place because the GV80 Black and GV80 Coupe Black are only offered with – you guessed it – a black exterior and interior.

Secondly, this G80’s interior is a plush mix of quilted Nappa leather upholstery with black suede inserts, black ash wood trim, an abundance of soft-touch surfaces and very impressive all-around fit and finish. The interior of the cabin makes a strong style statement but it’s not over the top.

Genesis Motors Australia also says it has used a range of eco-friendly materials, including leather upholstery and door trims dyed using recycled carbon-black extracted from waste tyres. So, there’s that.

The cabin more than matches its rivals, such as Audi Q7, BMW X5 and Mercedes-Benz GLE, in terms of pure styling and as for practicality? Well, keep reading…

Measuring 5243mm, 2030mm wide and 1782mm tall with a 3135mm wheelbase, the GLS63 is an upper-large SUV in every sense of the term, which means it’s also very practical.

For example, cargo capacity below the load cover is decent, at 355L, but stow the 50/50 power-split-folding third row via the boot and it’s very good, at 890L, or drop the 40/20/40 power-split-folding middle bench, too, and it becomes a cavernous 2400L.

Better yet, the boot’s aperture is almost square, and its floor’s flat, while there’s no load lip to contend with, making loading bulkier items even easier. Up to four tie-down points are also on hand (depending on seating configuration) to secure loose cargo.

Under the false floor is the space-saver spare, which is to be expected, but what isn’t expected necessarily is the fact there’s also enough room there for the cargo cover when it’s not in use, which would be the case if six or more passengers are regularly onboard.

Moving into the power-sliding second row, the GLS63’s practicality is once again brought to the fore, with up to six-plus inches of legroom available behind my 184cm driving position.

There’s also two inches of headroom with the panoramic sunroof in situ, not to mention just enough toe-room. The GLS63’s small transmission tunnel and sheer width also mean three adults can be seated on the middle bench with few complaints.

Amenities-wise, the second row has map pockets on the front-seat backrest and a small fold-down cubby below the rear climate controls, with it containing two slots for smartphones and a pair of strategically placed USB-C ports.

The rear door bins can take one large bottle each, while a fold-down central armrest is also on hand, featuring a shallow tray and retractable (and flimsy) cupholders.

Alternatively, the $2800 Rear Seat Comfort Package fitted to our test vehicle subs in a tablet that can control the multimedia system, a wireless smartphone charger and a small cubby into the former, as well as a heated/cooled cupholder atop the rear of the centre console.

In the third row, it’s not quite as roomy if you’re an adult. With the middle bench in its most accommodating position, my knees still brush up against its backrest, which is to be expected given it’s primarily designed for children. I also have an inch of headroom there.

Nonetheless, getting in and out of the third row is relatively easy as the power-operated middle bench tumbles forward and provides just enough space to make entry and exit somewhat graceful.

When seated, rear occupants are treated to two USB-C ports and one small cupholder each, so they’re arguably taken better care of than those in the middle.

Child seats are well and truly accommodated, with four ISOFIX and five top-tether anchorage points fitted across the second and third rows, although the latter will inevitably prove to be a much tighter fit.

The driver and front passenger are still taken care of, with a front cubby taken up by two heated/cooled cupholders, a wireless smartphone charger, two USB-C ports and a 12V power outlet, while their door bins take one large and one small bottle each.

In-cabin storage options include the large central storage bin, which hides another USB-C port, while the glovebox is on the smaller side, with about a third of it taken up by the fragrance, which is pumped into the cabin to ensure the interior always smells its best.

The GV80 Black is the same size as the standard GV80 – 4940mm long (with a 2955mm wheelbase), 1975mm wide and 1715mm high – so nothing has changed there.

And because the Black treatment is all about the looks, inside and out, the interior remains the same as standard for roominess and practicality. So, let’s dive into it.

First up, the 27.0-inch multimedia touchscreen dominates upfront, which is handy because it’s from here you operate most of the GV80’s controls. Thankfully, though, there are some physical dials and buttons, as well.

That screen is big, the colours are clear and crisp and the on-screen controls are easy to use, even for a true luddite like me.

Same goes for the driver display and the 12-inch head-up display. Clear to read and versatile enough in configuration choices to set them up as you want.

Then, everything flows on from that well-appointed dash.

The steering wheel is heated and power adjustable. By the way, I still don’t see why a heated steering wheel is a thing in Australia. Nowhere on this continent is cold enough to warrant it.

All seats are soft but supportive and very comfortable as you’d expect in a prestige vehicle with an interior that’s replete with “rich textures and bespoke materials”, according to Genesis.

There’s adequate seating room all-around, but the third row is squeezy and best suited to children or other height-challenged people that you despise.

The front seats are 18-way power-adjustable, heated and ventilated. They even have a massage function – if that’s your particular cup of tea.

The second row has heated and ventilated outboard seats (with power-base tilt and backrest recline), and there’s a climate-control panel each for the second and third rows.

Charge points abound with USB and 12V options available in the front and second row.

There are plenty of storage options throughout the cabin including a glove box, sunglasses case, cupholders etc. But the door pockets are narrow and awkward to get anything in and out of. A minor annoyance, but an annoyance, nonetheless.

In terms of cargo area capacity, with all three rows up and in use there is a claimed 327 litres of space available, 727L with the power-folding third row stowed away, and 2147L with the second and third rows folded down and out of the way.

Worth noting for anyone who drives beyond city limits is the fact this vehicle does not have a spare wheel, it only has a tyre mobility kit attached by Velcro to the rear cargo area floor.

The GV80 also has a power-operated tailgate.

The top-spec GV80 Black variants are based on the GV80 Signature 3.5T-GDi AWD and are only offered with that powertrain.

Our test vehicle, the seven-seat GV80 3.5T Black all-wheel drive SUV, has a Manufacturer’s List Price (MLP) of $136,250, while the five-seat GV80 Coupe 3.5T Black AWD has a MLP of $141,750. Both prices exclude on-road costs but include Luxury Car Tax where applicable.

Standard features onboard this test vehicle include:

• 27.0-inch OLED integrated multi-media touchscreen
• Wireless Apple CarPlay and Android Auto
• Built-in satellite navigation
• 18-speaker Bang & Olufsen audio
• 12.0-inch head-up display
• 18-way power-adjustable heated/ventilated/massage front seats
• Heated centre console
• Heated and ventilated second-row outboard seats (with power-base tilt and backrest recline)
• Second-row climate control panel
• Separate second- and third-row temperature control
• Power-operated tailgate
• Mood Curator (which is incidentally what I call the axe handle I keep by my bed for household protection)

Other features that set this Black variant apart from its stablemates include interior highlights such as a dark-tinted Genesis steering wheel logo, quilted Nappa leather upholstery (with black suede accents), welcome and goodbye animations, black ash real wood trim, black garnishes, bezels and switchgear and black aluminium speaker grilles.

Exterior highlights include black 22-inch wheels and brake calipers, black G-Matrix grille, dark-tinted Genesis front emblem and tailgate lettering and black body cladding.

All 2026 GV80s also get what Genesis calls a “Digital Key 2.0”, which enables users to lock and unlock front and rear doors and start the engine using a smart-phone or -watch. It can be stored on one device and shared with up to 15 devices.

Black is the exterior paint colour. Matt paint is optional and costs $2000.

The GLS63 is powered by a familiar 4.0-litre twin-turbo V8 petrol engine, with its version producing a thumping 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

This unit is mated to a nine-speed torque-converter automatic transmission and AMG’s fully variable 4Matic+ all-wheel-drive system with torque vectoring and a rear limited-slip differential.

This set-up also features Mercedes’ EQ Boost 48V mild-hybrid system, which actually gives a 16kW/250Nm electric boost in short bursts, such as when accelerating off the line.

Speaking of which, the GLS63 sprints from a standstill to 100km/h in just 4.2 seconds, while its top speed is electronically limited to 250km/h.
 

This Genesis GV80 Black has a 3.5-litre twin-turbocharged V6 petrol engine producing 279kW and 530Nm, matched to an eight-speed automatic transmission.

This SUV has an all-wheel drive system and an electronic limited-slip rear differential.

The GV80’s engine has plenty of punch and the auto is impressively cluey as well.

The GLS63’s fuel consumption on the combined-cycle test (ADR 81/02) is 13.0L per 100km, while its carbon dioxide emissions are 296 grams per km. All things considered, both claims are unsurprisingly high.

In our real-world testing, we averaged a fearsome 18.5L/100km over 65km of driving, split between highways and country roads, so not your usual mix. A very heavy right foot definitely influenced that result, but don’t expect to do too much better in a normal run.

For reference, the GLS63’s 90L fuel tank can be filled up with 98RON petrol at a minimum.

Official combined cycle (urban/extra-urban) fuel consumption is listed as 11.7L/100km.

On test we were seeing a dash-indicated 9.6-9.8L/100km but recorded an overall average of 12.4L/100km after a mix of city, highway and suburban driving.

The GV80 has a 80-litre fuel tank so, going by our on-test fuel figures, you can reasonably expect a driving range of about 645km from a full-tank.

Worth noting this car requires 95 RON premium fuel.

Frankly, the GLS63 has absolutely no right being as capable as it is. It’s a really big bus that’s legitimately convinced it’s a sports car half its size.

Being a GLS variant, the GLS63 has independent suspension consisting of four-link front and multi-link rear axles with air springs and adaptive dampers, but its party trick is the addition of active anti-roll bars.

In what feels like magic, the GLS63 is simply not intimidated by corners, despite having massive dimensions and a considerable 2555kg (kerb weight) to deal with.

The active anti-roll bars make the GLS63 so much easier to drive fast through the twisty stuff, almost eliminating body roll, taking one key variable out of the equation for the driver. Active engine mounts are also fitted, helping to settle things even further.

The electric power steering on hand is also good. It is speed-sensitive and has a variable ratio, which basically makes the set-up more direct when it needs to be. It’s typically light in hand, too, until one of the sportier drive modes is engaged and extra heft is added.

So, handling is scarcely believable, which means the ride must be compromised, right? Yes and no. With the adaptive dampers in their softest setting, the GLS63 is very compliant. In fact, we’d say it feels luxurious when compared to other high-performance SUVs.

That said, our test vehicle was fitted with the optional 23-inch alloy wheels ($3900), which look the part but expose sharp edges and other road imperfections, not to mention generate noise easily heard inside. Naturally, feedback is exacerbated in the sportier drive modes.

Anyway, there’s more performance, and the GLS63 has the rest in spades. Its engine is a powerhouse in every sense of the word. It’s so powerful, in fact, that it hilariously hunkers down off the line or when suddenly accelerating at low speed.

Thanks to the mild-hybrid system, wads of torque is available from the get-go, making for a highly responsive driving experience, even in those rare moments when the engine isn’t on song.

While not as characterful as some of the other members in the 63 series, the GLS63 still makes some thoroughly entertaining noises, with its sports exhaust system popping like mad while on the overrun.

All of this ability is very well and good, but you need to be able to pull up quickly, and the high-performance braking package (400mm front and 370mm rear discs with six-piston fixed callipers and single-pot floating stoppers respectively) mercifully does exactly that.

An excerpt from my initial drive notes on the GV80 Black read "smooth, slick (too slick?), impressive open-road cruising, plush, couch on wheels”. All sound points but there’s even more to this car.

For a big wagon, the circa-2345kg GV80 gets off the mark nicely with a crisp throttle response and it punches along at a fair clip once on the move. There’s little to no noise from the outside world, other than the low-key rumble of the V6 and it’s easy to hit the speed limit without realising.

The power-adjustable steering wheel can be dialled in for a preferred position and while this weighty AWD still exhibits minor body roll through tighter corners that characteristic can be restrained somewhat via the Sport drive mode for better suited suspension behaviour and controlled with sufficiently precise steering.

Ride and handling are well sorted out with the GV80’s all-wheel drive system and an electronic limited-slip rear differential giving the driver welcome levels of confidence in a variety of driving conditions.

Turning circle is listed as 11.98m and this car doesn’t feel unwieldy on busy suburban streets.

A few niggles. Digital rear-view mirrors are not among my favourite features in cars as they offer a headache-inducing fish-eye view of the world not to my liking and such is the case in this GV80.

Speaking of views, because the GV80 is low and sleek, it doesn’t afford the driver the levels of visibility I’m used to getting in the taller, more upright vehicles I most frequently review.

All-around, however, the GV80 is a smooth daily driver, with plenty to like about it and just a few foibles.

The Genesis GV80 3.5T Black does not have an ANCAP safety rating because it has not been tested.

As standard it has 10 airbags (including side curtain airbags) and driver-assist tech includes forward collision-avoidance assist, lane keep assist, highway driving assist, smart cruise control, a surround-view monitor and more.

The second row has ISOFIX child-seat anchors in the two outboard seats, and three top-tether points.

As with all Mercedes-AMG models, the GLS63 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 GLS63’s service intervals are relatively long, at every 12 months or 20,000km (whichever comes first). Better yet, it’s available with a five-year/100,000km capped-price servicing plan, but it costs $4450.

Every new 2026 GV80 is covered by a five-year/unlimited km warranty and five years' roadside assistance. If the car's serviced at an authorised Genesis dealer this coverage increases to 10 years.

Servicing, scheduled for every 12 months or 15,000km, is free for the first five years or 75,000 km, whichever occurs soonest. Genesis offers a concierge and courtesy vehicle service for five years with the complimentary service.

There are 11 Genesis dealers in Australia - Five in Sydney (including a CBD 'studio'), two in Melbourne and one each in Brisbane, The Gold Coast, Adelaide and Perth.
