Mercedes-Benz GLB-Class vs Genesis GV80

What's the difference?

The new GLB is a worthy successor to the original. It has retained everything that made it such a unique proposition but improves where it counts - interior space and comfort, in-car and safety tech, standard features, powertrain, ride quality and, importantly, value-for-money.

The EV is the pick of the powertrains and while I didn’t get to drive it, the GLB250+ is the best value.

Servicing is expensive and the standard glass roof is a bugbear but if you can cope with those things, the boxy GLB is a terrific smallish family SUV.

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.

The original first-generation GLB was a standout when it comes to exterior design. It was boxy, upright and unlike anything else in the premium SUV segment. If you wanted a conventional Mercedes SUV you could opt for the smaller, bubble-shaped GLA or the larger, more sophisticated GLC.

But the GLB occupied its own space. Thankfully Benz has largely stuck with the script for the second-gen GLB, but they’ve modernised it.

Built on the new Mercedes Modular Architecture (MMA), the GLB is a full 98mm longer, has a 50mm longer wheelbase, is 27mm wider and 14mm shorter. And it does look noticeably lower to the ground compared to the old model.

While the square silhouette remains, Benz’s latest design direction is seen everywhere. The front end is more rounded now and has a large gaping low-set grille with an LED light bar running the width of the bonnet. It’s an acquired taste but I prefer the previous GLB face.

The rear is a much better angle for the GLB. Looking at it directly from the rear, it has pronounced shoulders that give it a lovely muscular look, and the curved tail-lights are a highlight.

Benz is leaning into its brand in a bid to stand out in an increasingly competitive global market. It’s doing this by using the iconic three-pointed star as a motif in the head and tail-light cluster, as well as the grille which is illuminated for some grades. I’m not sold on that element as it feels a bit over the top, but at least you won’t get confused about what brand of car it is.

Another design element I’m not sold on is the pop-out door handles. With car companies finding better solutions for handles, this seems out of touch.

Inside, everything feels upright. The integrated glass dash panel spans the width of the cabin, while brushed aluminium panels also feature. The signature Benz seat adjuster switches on the doors and the gorgeous air vent design have been upgraded successfully.

The three-spoke leather steering wheel in the GLB350 is a highlight - it’s the perfect width and well executed.

Overall the design is modern, tech focussed and very Benz.

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…

The extra length and width means more cabin space which is more apparent in the rear. But there is ample space up front, especially headroom.

The centre console sits up a little too high for my liking but it means you have under console storage with two USB-C ports, and a rubber mat so your phone doesn’t slide around.

It’s got a really deep central bin, while door cavities will only hold smaller bottles. You also get a wireless charger and two cupholders.

There is only a handful of buttons - hazard lights, volume, voice command and drive mode selection - under the central air vents. All other functions are found in the multimedia screen.

Benz has been a standout in the past decade with its MBUX multimedia system and the latest version is responsive, relatively easy to navigate (once you’ve located the key controls), and the graphics look super sharp and cool. The digital instrument cluster is similarly excellent.

Hopping into the second row, the seat base is set higher than the front seats for stadium seating. The seats have some bolstering but quite a lot of lumbar support.

There’s ample space in the second row, thanks to 68mm more space from the back of the seat to the front seat and an extra 34mm of headroom compared to the old car. I have ample knee, head and legroom behind my 183cm (six-foot) tall driving position, although my head is about the same height as the top of the window frame which impedes a little.

Amenities include smallish map pockets, two USB-C ports and knee-level air vents, which is always good to see. There’s a deep but skinny bottle holder on either side and a fold-down centre armrest that sits up a bit too high but it’s wide and has two shallow cupholders and a neat little phone holder.

Each of the 40/20/40 split seats folds via a pull strap at the seat base and the good news is you can adjust the second row backrest a little. The base is also on rails so it can slide fore and aft.

That is how you lower the seats to get into the third row, which is strictly for children. Benz has made it slightly easier for littlies to get back there but it is not a space for taller humans. In fact, Benz recommends up to 171cm tall at most.

One gripe is that there is no sunshade or blind for the massive standard panoramic fixed glass roof. Benz says it is tinted and has a film to reduce UV light and heat, but I’d say a few hours driving in Australian summer will challenge that. Benz isn’t the only brand doing this, but at least you can buy an accessory blind for your Polestar or Tesla. The fact is, not everyone wants a glass roof, especially in Australia, so this feature should be an option.

The boot can swallow 145 litres with all three rows up, increasing to 480L with the third row stowed and 1605L will all seats lowered. This is all decent for a smallish seven seater but if boot space is a priority then maybe have a look at a GLC.

There’s a floor mat and cargo blind but sadly no spare wheel of any kind, just a tyre repair kit, which isn’t great.

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.

Both mild-hybrid versions of the GLB are powered by a 1.5-litre four-cylinder turbo-petrol engine with 48-volt mild-hybrid tech that includes a 1.3kWh lithium ion battery.

The front-wheel-drive GLB200 delivers 120 kilowatts of power and 250 Newton metres of torque for an 8.7-second 0-100km/h dash time.

The all-wheel drive GLB220 4Matic gets a power and torque boost to 140kW/300Nm for a 7.5-second 0-100km/h time. Both petrol grades use an eight-speed dual-clutch automatic transmission.

For the EVs, the rear-drive GLB250+ delivers 200kW/335Nm and hits 100km/h from zero in 7.4 seconds.

The GLB350 4Matic ups that to 260kW/515Nm and a 100km/h dash time of 5.5 seconds.

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 GLB EVs uses a nickel manganese cobalt (NMC) battery with 85kW of usable energy.

Driving range and energy efficiency for the GLB250+ is a decent 570km and 15.5 kilowatt hours per 100km. The two-motor AWD GLB350 range drops slightly to 554km and uses 17.7kWh/100km

The EVs have four regenerative braking modes. After a long morning drive in the GLB350 I recorded 15.5kWh, which is solid.

The new GLB uses an 800-volt architecture supporting DC fast charging up to 320kW. Under the right conditions at a high-powered DC charging station, you can technically add up to 260km of range in 10 minutes, according to Mercedes.

AC charging capacity is available up to 22kW and there are four regenerative braking modes, as well.

When it comes to fuel economy in the mild hybrids, the GLB200 consumes 6.1 litres per 100km and the GLB220 sips 6.5L. This powertrain has the ability to use electric power to coast when cruising at highway speeds.

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.

I have driven the previous GLB250, which was a fun, punchy SUV. There’s no sporty second-gen variant yet, but if you’re after performance, check out the EV rather than the mild-hybrid.

I only drove the mild-hybrid briefly at the launch event so I’ll focus most of my impressions on the EV. The GLB220 4Matic is quick enough off the line, but there is some lag. Brakes are strong and the cabin is well insulted.

But for me, the EV is the clear pick.

Of the EVs I only drove the GLB350 4Matic as Benz didn’t have a 250+ available.

It’s very quick from a standing start, but not whiplash quick and that is perfectly appropriate for a family-friendly SUV. It delivers the power in a linear manner but when you put the foot down it is very responsive.

I couldn’t detect a massive difference between Comfort and Sport mode to be honest, but you get enough punch in Comfort.

The GLB is tall and top heavy so there is body roll but that’s fine for this sort of vehicle. You’ll notice the weight of this car if you push it into a tight bend at speed - it’s quite heavy and I felt a bit of lateral movement, but the traction control systems help keep the car in check. The grippy tyres help here, too.

Benz has worked hard to improve ride quality with the new-gen model and it shows. The drive route from Melbourne’s south-eastern suburbs to the Mornington Peninsula was littered with potholes, some that looked like they could cause serious damage. The GLB soaked up even some of the sharper holes like a pro. The ride at urban speeds is calm and measured.

The sound deadening measures have clearly helped as well as it is a much quieter cabin than its predecessor. All of this adds to the feeling that this GLB is a more refined, premium SUV than the old model.

I found the steering a little light and twitchy at the start of the drive but by the end of the day I noticed some heft to the feel, and it’s still direct.

The brakes in the EV are a little slower to respond than the mild-hybrid, which takes some time to get used to.

But overall, the drive experience is largely very positive.

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.

The GLB comes with Mercedes’ five-year, unlimited kilometre warranty, which is now the standard in the premium segment. The EV’s battery warranty lasts eight years or 160,000km, which is also pretty standard.

Services are required every year or 25,000km which is a decent interval.

Benz offers pre-paid service packages running for three, four or five years. The mild-hybrid is $3430 for three years, $4680 for four and $6300 for five years.

The EV is more affordable to service, costing $2525 for three, $3765 for four and $4440 for five years.

This is quite pricey compared to rivals. BMW’s iX3 is offered with a six-year pre-paid plan and it’s $2420. The Polestar 4 is free to service for the first five years.

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.
