Mercedes-Benz GLB-Class vs Mercedes-Benz Maybach

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.

It’s big, it’s bold and totally baller, but that’s kind of the point.

The Mercedes-Maybach GLS 600 might not win over many fans with its in-your-face design or its sky-high price tag, but there is definitely an appeal here.

Taking luxury to another level is no easy feat, especially in a Mercedes, but the attention to detail, lavish second row and butter-smooth V8 engine combine to turn the already-good GLS into this exquisite Maybach.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

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.

If you have wealth, why not flaunt it? I reckon that might be the philosophy of the Maybach designers back at HQ, and it kind of shows!

The styling of the Maybach GLS might be the most controversial thing about it. But honestly, I love it!

The liberal lashings of chrome, the three-pointed star hood ornament, and especially with the optional two-tone paintwork, it’s all just so over the top and in your face that it brings out a smile.

From the front, the Maybach is also distinguished by an imposing grille that gives it serious presence on the road, while the profile is characterised by massive 23-inch multi-spoke wheels – better park well clear of any gutters!

You’ll also notice the Maybach eschews the usual black-plastic cladding around the wheelarches and underbody found on lesser/cheaper SUVs in favour of body-coloured and gloss-black panels.

There is also a little Maybach badge on the D-pillar, which is a nice attention-to-detail touch. From the rear, there’s more chrome, while the dual exhaust outlets hint at the performance on offer. But it’s inside where you really want to be.

Everything in there is just a sea of soft-touch and premium materials, from the dashboard to the seats and even the carpet under your feet.

Though the layout of the interior mirrors the GLS, the extra detailing, like the Maybach-stamped pedals, unique multimedia surround and woodgrain steering wheel, elevates the cabin into something truly special.

And if you opt for the comfort rear seats, well they wouldn’t look out of place on a private jet.

The second-row seats also feature contrast stitching on the headrests, cushions, console and doors for that add a touch of class.

I can see the Maybach GLS might not be to everyone’s tastes, but it certainly stands out from the sea of samey-looking luxury SUVs out there.

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.
 

The Maybach GLS is based on Mercedes’ largest SUV offering to date, which means there is plentiful room for occupants and cargo.

The front row feels positively palatial, with heaps of head-, leg- and shoulder-room for six-foot (183cm) tall adults.

Storage options include generous door pockets with room for large bottles, two cupholders, a smartphone tray that doubles as a wireless charger, and an underarm storage cubby.

But the rear seats are where you want to be, especially with these second-row comfort seats fitted.

It’s rare when there is more room in the rear than the front, but it does makes sense for a car like this, especially when you consider the GLS this car is based on is a three-row vehicle.

The removal of seats six and seven mean there is more room in the second row, especially with the comfort seats fitted, allowing you to recline fairly flat and to get into a comfortable position.

Storage is also plentiful in the second row, with a bespoke centre console in our test car, the aforementioned drinks fridge, backseat storage and a nice door bin.

Open the boot and you will find 520 litres (VDA) of volume, which is plenty for golf clubs and holiday luggage.

However, if you opt for the rear seat refrigerator, the cooler box will eat into boot space.

The best things in life might come free, but the most luxurious things certainly come at a cost.

Wearing a price tag of $378,297, before on-road costs, the Mercedes-Maybach GLS 600 is probably out of the reach for most mere mortals, but there’s no denying Mercedes has thrown in a lot for the spend.

And with it positioned nearly $100,000 north of the Mercedes-AMG GLS 63 ($281,800) – with which it shares its platform, engine and transmission – you’d want to get a bit of bang for your buck.

Standard features include keyless entry, push-button start, Nappa leather interior trim, a head-up display, a sliding glass sunroof, power-closing doors, heated and cooled front and rear seats, and interior ambient lighting.

But, as the epitome of Mercedes’ luxury SUVs, the Maybach also scores 23-inch wheels, a heated woodgrain and leather steering wheel, open-pore wood trim and five-zone climate control – one for each passenger!

Handling multimedia duties is Mercedes’ 'MBUX' 12.3-inch touchscreen display, complete with satellite navigation, Apple CarPlay/Android Auto support, digital radio, a premium sound system and wireless smartphone charger. 

Rear seat passengers are also treated to an entertainment system with TV tuner so you can keep up with the Kardashians from the road, as well as a bespoke MBUX tablet with functions for climate, multimedia, satellite navigation input, seat controls, and more.

Sadly, the Samsung-branded tablet glitched out a few times while we were using different functions and required a reset.

No doubt, a software update can fix some connection issues, but it's still something that shouldn’t be happening in a high-dollar, ultra-lux SUV.

Options with the Maybach GLS are surprisingly limited, with buyers able to choose between different exterior colours and interior trims, second-row comfort seats (as fitted on our test car), and a rear champagne chiller box.

Look, nearly $400,000 for an SUV might seem like a lot, but you really are wanting for nothing with the Maybach GLS, and it's comparable in price to other high-end SUVs like the Bentley Bentayga and Range Rover SV Autobiography.

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.

Powering the Mercedes-Maybach is a 4.0-litre twin-turbo petrol V8 – the same engine you will find in many AMG products like the C 63 S and GT coupe.

In this application, the engine is tuned to produce 410kW and 730Nm, which is admittedly less than you get in something like the GLS 63, but the Maybach isn’t designed to be an outright powerhouse.

With drive sent to all four wheels via a nine-speed automatic transmission, the Maybach SUV will accelerate from 0-100km/h in just 4.9 seconds – also helped by a 48-volt mild-hybrid 'EQ Boost' system.

Though not designed for outright grunt, the Maybach GLS’s engine is nicely tuned to deliver smooth power and seemless shifting

The Maybach is more than a match for rivals such as the Aston Martin DBX (405kW/700Nm), Bentley Bentayga (404kW/800Nm) and Range Rover P565 SV Autobiography (416kW/700Nm).

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.

Official fuel consumption figures for the Mercedes-Maybach GLS 600 are pegged at 12.5 litres per 100km, and it’s recommended to fill up with 98 RON premium unleaded, so be prepared for a big fuel bill.

This is despite the 48-volt mild-hybrid tech that lets the Maybach coast without using fuel in certain conditions, and extends start-stop functionality.

In our brief time in the car, we managed to get 14.8L/100km. Why is the Maybach so thirsty? That’s simple, it’s weight.

All the cool features like Nappa leather interior, woodgrain trim and 23-inch wheels add weight to the overall package, and the Maybach GLS tips the scales at nearly three tonnes. Ouch.

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.

While you might not find many owners of the Maybach GLS in the driver’s seat, it’s nice to know it can hold its own in the driving dynamics department.

Don’t get me wrong, this won’t give the AMG-blessed GLS 63 a run for its money, but the Maybach SUV is far from dull.

And the engine plays a large part in this. Sure, it’s not as savage as some AMG models, but there is still plenty of grunt to come out of corners with enthusiasm.

The tune of the engine is obviously weighted towards smoothness and comfort, but with 410kW/730Nm on tap there is enough there to make things feel urgent.

The nine-speed automatic transmission also has to be called out, as it is calibrated in such a way that the shifts are imperceptible. There’s none of that mechanical jerkiness and clunkiness involved in swapping cogs, and it just makes the Maybach GLS feel that much more luxurious.

The steering, while straying a towards numb, still offers plenty of feedback so you know what’s happening underneath, but it’s the active body control that works to keep this hefty SUV in check in the bends.

The best bit, though, has to be the air suspension, which floats the Maybach GLS over bumps and uneven roads like a cloud.

The front-facing camera can also read the terrain ahead and set-up the suspension for incoming speed bumps and turns, taking comfort up to a whole new level.

All this is to say, yeah, the Maybach might look like a boat, and cost as much as a boat, but it doesn’t actually feel like a boat behind the wheel.

But really, are you buying this car because you want to be the driver? Or are you buying one because you want to be driven?

In the second row, it’s as close as you’ll get to a first-class flight on the road, and the seats are genuinely plush and cosy.

It’s eerily quiet and supremely comfortable in the second row, leaving you free to carry on with important business like drinking your champagne or uploading to the 'gram.

And while I usually suffer from a bout of motion sickness within minutes of looking at a phone in a car, I didn’t feel such ill effects in the Maybach GLS.

Even after about 20 minutes scrolling through Facebook and emails while being driven around, there was no sign of a headache or queasiness, which is all thanks to how well the suspension is tuned and the active anti-roll technology doing its thing.

The Mercedes-Maybach GLS 600 has not been tested by ANCAP or Euro NCAP, and therefore doesn’t wear a safety assessment rating.

Despite this, the safety equipment found on the Maybach is comprehensive. As standard, there are nine airbags, a surround-view camera system, autonomous emergency braking (AEB), tyre pressure monitoring, traffic sign recognition, front and rear parking sensors, rear cross-traffic alert, and automatic high beams.

Mercedes’ 'Driving Assistance Package Plus' is also included, bundling adaptive cruise control, lane-keep assist and blind-spot monitoring.

The 'Urban Guard' suite also adds an alarm, tow-away protection, parking damage detection, and an interior motion sensor, which can send notifications to your 'Mercedes Me' app.

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.

Like all new Mercedes models sold in 2021, the Maybach GLS 600 comes with a five-year/unlimited kilometre warranty with roadside assist over that period.

This is class-leading in the premium segment, with only Lexus, Genesis and Jaguar able to match the warranty period, while BMW and Audi serve up assurance periods lasting only three years.

Scheduled servicing intervals are every 12 months or 20,000km, whichever occurs first.

While the first three services will cost owners $4000 ($800 for the first, $1200 for the second and $2000 for the third service), buyers can opt to save some money with a pre-paid service plan.

Under the service plan pricing, three years of maintenance will cost $3050, while four- and five-year plans are on offer at $4000 and $4550 respectively.
