Mercedes-Benz GLB-Class vs Genesis GV80

What's the difference?

It’s easy to say the GLB35 doesn’t deserve to be called an AMG when looking at its credentials on paper, but get behind the wheel and it’s evident Affalterbach played a key role in making it feel as special to drive as it should be.

The GLB35 has all of the great qualities of the GLB250 and other GLB variants, but successfully adds a performance focus to make for an even more compelling package.

Indeed, the GLB35 proves you can pretty much have it all.

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.

With the boxy and therefore rugged-looking GLB laying some great foundations, it’s no surprise the GLB35 looks pretty damn good – to these eyes, at least.

Being an AMG model, it stands out from the crowd with an aggressive body kit, with the chunky bumpers, aerodynamic roof spoiler and racy rear diffuser all unique alongside the now-signature Panamericana grille insert.

A set of 20-inch alloy wheels with 255/40 tyres ups the ante at the side, where the carryover black plastic wheel-arch and skirt cladding serves as an obligatory reminder that this is an SUV.

Also of note are the nicely designed LED headlights and tail-lights, which literally light the way, but there’s no getting past the bespoke diffuser element, which integrates the sports exhaust system’s dual 90mm tailpipes.

Inside, the GLB35 is a technological tour de force, with a pair of 10.25-inch high-resolution displays proudly sitting side by side atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes-Benz’s MBUX multimedia system, which arguably remains the best there is today thanks its speed and breadth of functionality and input methods.

The GLB35 is also properly premium. Lugano leather upholstery covers the seats and armrests, while Nappa trims the sports steering wheel. Even the door shoulders and inserts get ‘cow hide’, although theirs is of the artificial variety.

Soft-touch materials are used for the upper dashboard, leaving hard plastics to the lower sections, which is what you’d expect for the price.

While the black headliner makes for a dark cabin, brightness comes from the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let’s not forget the pop of colour provided by the addictive ambient lighting.

And mercifully, scratch- and fingerprint-hungry gloss-black accents are limited to the surrounds of the turbine-style front air vents, dual-zone climate controls and centre console.

Unique to the GLB35 are Carbon Structure trim and stainless-steel sports pedals, just in case you forgot you weren’t driving a regular GLB.

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.

Measuring 4650mm long (with a 2829mm wheelbase), 1845mm wide and 1660mm tall, the GLB35 is more like the GLC43 in size than the GLA35, making it a mid-size SUV despite its small underpinnings. And that is good news for practicality.

Cargo capacity with the 50/50 split-fold third row stowed is more than solid, at 565 litres (VDA), but it can be increased to a cavernous 1800L with the 40/20/40 split-fold middle bench also not in use. If six or seven passengers are onboard, though, there’s very little room to move.

Nonetheless, the boot is still well packaged, featuring a huge aperture, no load lip, and a flat floor, which make loading and unloading bulkier items a hell of a lot easier. And even the load cover can be stored underfloor when out of action. How good.

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet on hand to make matters even easier, while the rear seats can be stowed from the boot.

While we’re on the topic, Mercedes-Benz says the third row can accommodate passengers up to 168cm tall, with the middle bench able to slide fore and aft by up to 140mm.

Yes, I'm too tall, at 184cm, but I can still sit in the very back, although not in total comfort. All in all, about a centimetre of legroom and negligible headroom and toe-room are on offer there for me.

That said, getting in and out in the first place is the real challenge here, with the middle bench unable to tumble forward for easy ingress and egress. Yep, you’re not going to look smooth either way. Children can deal with it, but adults won’t be thrilled.

Therefore, the middle bench is the place to be, even when it’s slid all the way forward. Behind my driving position, it offers about a centimetre of legroom, but this can be increased to several inches by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an inch of headroom. The latter is more impressive when you consider that’s what you get with the standard dual-pane panoramic sunroof fitted.

Even better, the second row can seat three adults at a pinch, partly thanks to the low transmission tunnel, which means there’s the right amount of space for six fully grown feet across the two footwells. It goes without saying children will again be fine.

Speaking of which, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, which makes the GLB35 a serious option for families that like to be sporty.

There are plenty of in-cabin storage options, with the large central storage bin featuring a pair of USB-C ports, while the glovebox is also quite useful, even if it is oddly shaped. And there’s also a sunglasses holder in front of the rearview mirror.

The centre console’s cubby isn’t really designed for storage, with it basically taken up by two cupholders, another USB-C port and a wireless smartphone charger.

The front door bins can accommodate one small and two regular bottles each, which is great, while their rear counterparts can take one small and one regular apiece.

Second-row occupants also have access to a fold-down armrest with another pair of cupholders, but being of the retractable variety, they’re flimsy.

These passengers also have two USB-C ports, with the pair folding out below a small cubby and air vents, which are found at the back of the centre console. Storage nets are also fitted on the front seat backrests.

And don’t worry; the third row gets in on the action, with two cupholders (one regular, the other small) splitting the seats, which have individual USB-C ports and device straps to the sides.
 

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.

The GV80 line-up has seen a model facelift for 2025 and the flagship’s powerful V6 engine now comes standard for all models. There's new tech and some design tweaks, too.

That means the price points are starting to creep a lot closer to their Euro rivals as the 3.5T Luxury AWD Coupe is priced from $136,000, before on-road costs.

However, despite only being offered in one variant for our market, the coupe is is ridiculously well-specified and you don't have to add luxury/enhancement packs at additional costs as you do on some of this car's rivals (I'm looking at you Range Rover).

In comparison, the closest rival, the BMW X6 xDrive40 MHEV, sits at $144,900 MSRP, and then the Range Rover Velar Autobiography comes in at $156,430 MSRP before the most expensive rival, the Mercedes-Benz GLE 450 4Matic Coupe, at $159,900 MSRP.

When I start talking about the GV80 Coupe's standard features I lose breath trying to list them all and you're about to learn why.

For comfort and luxury the Coupe is offered with crystal accents on its dials, Nappa leather upholstery, suede trims, a heated steering wheel and a panoramic sunroof.

The front seats are powered and feature a two-position memory function, lumbar- and side-bolster adjustments, extendable under-thigh supports, heat and ventilation functions... and a massage function.

Rear outboard seats are also powered and can be slide backwards/forwards and recline. They feature heat and ventilation functions as well.

Practical features include a powered tailgate with a proximity opening feature, retractable sun blinds (rear row), tri-zone climate control, keyless entry, push-button start, remote start and parking assist (via key fob), carwash and valet mode, and new for 2025, a biometrics system (fingerprint access for vehicle start and profile selection).

Technology includes a new 27-inch OLED screen that houses the multimedia system and instrument cluster, customisable ambient lighting, wired Apple CarPlay and Android Auto, over-the-air updates, satellite navigation, 12-inch coloured head-up display, digital rear view mirror, four USB-C ports, three 12-volt sockets, a wireless charging pad, Bluetooth connectivity and digital radio.

Phew... told ya there's a lot. Oh, and an 18-speaker Bang & Olufsen sound system. There. Done.

The GLB35 is powered by an uprated version of the GLB250’s 2.0-litre turbo-petrol four-cylinder petrol engine, with the AMG-fettled version producing a more substantial 225kW of power from 5800-6100rpm and 400Nm of torque from 3000-4000rpm (up from 165kW/350Nm).

This version is also matched to an eight-speed dual-clutch automatic transmission as well as Mercedes-AMG’s front-biased but fully variable 4Matic all-wheel-drive system.

Thanks to this combination, the GLB35 can sprint from 0-100km/h in just 5.2 seconds with launch control enabled, while its electronically limited top speed is 250km/h.

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.

The GLB35’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.3L per 100km, while its carbon dioxide emissions are 186 grams per km. All things considered, both claims are pretty decent.

In our real-world testing, though, we averaged a high 14.1L/100km over 75km of driving split between highways and country roads, so not your typical mix, then. A heavy right foot also played into that result, so expect a better return after a regular run.

For reference, the GLB35’s 60L fuel tank can be filled up with 98RON petrol at minimum.

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.

Don’t let the GLB35’s family friendliness fool you, this is an SUV that can get up and go.

The engine’s extra power and torque over the GLB250 are immediately felt behind the wheel, with the GLB35 accelerating with the vigour of an all-wheel-drive hot hatch, which makes sense given their similar claims.

And if you have one of the sportier drive modes engaged, the booming noise generated is also special – even if a lot of it is of the artificial variety, pumped into the cabin to make occupants feel like things are getting serious.

What is genuine, though, is the well-rounded transmission, which is characteristically quick with its upshifts. At the same time, it’s also relatively smooth, even at low speed, which has proven to be a challenge for dual-clutch units over time, but not here.

To earn the AMG badge, the GLB35 goes even further with other mechanical upgrades, including sports tunes for the suspension and steering.

Specifically, the GLB35’s independent suspension set-up not only consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers, but also introduces new steering knuckles, transverse control arms on the front axle, and a stiffened subframe.

The resulting ride is actually quite good. Yes, the extra firmness over the GLB250 is noticeable – particularly in the sportier drive modes that stiffen the adaptive dampers all the way – but it’s by no means a deal-breaker.

That said, it’s worth noting our test vehicle was fitted with the optional 21-inch alloy wheels ($1990), so the GLB35’s like to ride even better on its standard package.

This is remarkable considering the handling improvements made, with the GLB35 managing body roll and pitch better than the GLB250 when pushing hard into and around corners, coming out of which grip is plentiful thanks to the all-wheel-drive system.

Thankfully, the standard-fit high-performance braking package consisting of 350mm front and 330mm rear discs with four- and one-piston callipers respectively helped it wash speed away with ease when attacking the twisty stuff with intent, even with 1857kg (kerb) to deal with.

Also on hand is electric power steering, which is speed-sensitive and has a variable ratio in the GLB35. Basically, it’s quicker when you want it to be, remaining on the lighter side in hand until you engage one of the sportier drive modes and weight is increased markedly.

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.

For those concerned with safety, you needn’t worry as the GV80 Coupe has a maximum five-star ANCAP safety rating from testing done in 2021 and scored highly for its adult and child protection scores at 91 per cent and 88 per cent, respectively.

Standard safety features include rear cross-traffic alert, lane departure alert, lane keeping aid, traffic sign recognition, intelligent seatbelt warning, a head-up display, adaptive cruise control, blind spot monitoring, blind-spot view monitor, parking assist pilot, driver attention alert and safe exit warning.

Other features include child occupant alert, leading vehicle departure alert, tyre pressure monitoring, LED DRLs, a 360-degree view camera system and front and rear sensors.

The GV80 Coupe comes with AEB with forward collision warning, car, pedestrian, cyclist and backover detection which is operational from 5.0–200km/h (up to 85km/h for car detection).

The GV80 features 10-airbags, which is great for the class!

There are ISOFIX mounts on the rear outboard seats plus three top tethers and you might get three seats installed if they’re not too big but two will fit best.

As with all Mercedes-AMG models, the GLB35 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 GLB35’s service intervals are long, at every 12 months or 25,000km (whichever comes first). Better yet, it’s available with a three-year/75,000km capped-price servicing plan, but it costs $2750, with the third visit alone incurring a $1300 charge.

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.
