Lexus NX300 vs Mercedes-Benz Gls600

What's the difference?

The Lexus NX 300h F Sport is both a comfortable and luxurious family hauler that is held back by just a few things.

Of course, gripes like the underwhelming dynamics might not be an issue for all, but the less-than-stellar fuel economy (for a hybrid, at least), disappointing practicality and fiddly multimedia will affect all potential buyers.

However, this is balanced out by loads of equipment and premium appointments for a reasonable price, which should put the Lexus NX on your shopping list if you are keen for an inner-city premium SUV cruiser.

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.

Lexus might have been known for drab and dowdy styling in the past, but the NX’s sharp aesthetic is head turning and attention grabbing in all the right ways.

Though the NX first hit Australian showrooms in 2014, after six years we reckon it wouldn’t look out of place strutting down a catwalk, and can easily hold its own in the design department against the likes of the Audi Q5, BMW X3 and Mercedes-Benz GLC.

From the front, you can’t miss the trademark Lexus spindle grille, which, with its trapezoidal shape, gives the illusion of a wider and more aggressive car.

The high-set, slender headlights also gives the NX a wide stance, while the sweeping daytime running lights and sharp bumper design give the impression that the NX is cutting through water.

In profile, the NX is characterised by a strong shoulder line, chiselled lower doors and narrow glasshouse, while the black plastic wheelarch cladding hints at its SUV status.

The black trim detailing on the tail-lights almost make it look like the NX has narrowing cartoon eyes from the rear, but the subtle diffuser and large bumper soften its look a little.

If you can’t tell, we dig the aesthetics of the NX, especially the subtle exterior features such as crystal-like front foglights and the unique side mirror design.

Step inside and those neat little design touches continue.

From the almost folded fabric-like design of the door trims to the soft-touch surfaces throughout, the NX’s cabin oozes luxury, class and quality.

The centre stack shape mirrors the front grille’s trapezoid shape, while all the buttons and switchgear have a nice heft and weight to them, and are laid out in an easy-to-use, ergonomic fashion.

Sure, look a bit closer and you might see some carryover items from lower-end Toyota models, such as the cruise control stalk but, be honest, if we didn’t point it out, would you have even noticed?

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 4660mm long, 1870mm wide, 1645mm tall and with a 2600mm wheelbase, the NX puts it foot firmly into the mid-size SUV class.

Front occupants can easily get comfortable thanks to seats with a wide breadth of adjustment, while drivers also get a telescoping steering wheel that automatically raises when the car is turned off for easier ingress/egress.

Generous door bins up front will swallow large water bottles and any other paraphernalia, while two deep cupholders are found between the driver and front passengers.

If you want to tuck any items out of sight though, the glovebox and centre console bin will do the job, but there is also a hidden compartment where the driver’s touchpad palm rest.

Lift up the flap and your precious valuables can be hidden away, but look underneath the flap and it doubles as a handheld mirror to check you don’t have any food in your teeth before a date.

The outer two second-row seats offer ample room for six-foot-tall passengers, and – even with the front seats in our preferred position – there is plenty of legroom in the back.

Like most vehicles, the middle seat is a bit compromised, but in the NX it feels especially narrow and uncomfortable.

This isn’t helped by the middle seat’s seat belt, which comes down from the roof and intrudes well into the backrest of the neighbouring seat when not in use.

It makes loading the NX full of passengers tricky as there is a bit of shuffling around to get all the belts in place and passengers comfortable.

Our advice? Use the NX as a four-seater and just fold down the centre armrest, which also exposes two cupholders, for extra comfort.

Other rear seat amenities include air vents and storage pockets in the doors, the latter of which will accommodate water bottles or small items.

Open the boot and the NX will swallow 475 litres of volume, which can expand to 1520L with the rear seats folded down.

Boot space is down on its rivals, with all of the German models offering at least 550L of volume.

In real-world terms, this means the NX’s boot won’t close with a large- and medium-sized suitcase sat side-by-side, but has no problem with smaller cases.

Boot space might be lacking in the NX, but the hybrid system’s batteries have to go somewhere, and at least Lexus offers up two big bag books and tie-down points.

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.

Propelling the Lexus NX 300h F Sport is a petrol-electric mild-hybrid powertrain, combining a 114kW/210Nm 2.5-litre naturally aspirated four-cylinder petrol engine with two electric motors – 105kW/270Nm unit for the front axle and a 50kW/139Nm unit for the rear wheels.

The total system output is measured at 147kW, which is sent to all four wheels in our test var via a continuously variable automatic transmission (CVT).

The zero-to-100km/h acceleration takes 9.2 seconds thanks to a fairly hefty 1895kg kerb weight.

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).

Official fuel consumption figures for the Lexus NX 300h is 5.7/ litres per 100km, though we managed a 7.6L/100km figure in our week with the car.

Our driving consisted exclusively of inner-city driving for groceries and just two trips down the freeway upon collecting and returning the car due to Melbourne’s lockdown rules.

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.

Though the Lexus NX might look sporty and dynamic from the outside, don’t be mistaken into thinking Lexus’ mid-size SUV is anything other than a comfy cruiser.

Steering remains light and lifeless in its default ‘Nomal’ drive mode, but even in ‘Sport S’ and ‘Sport S+’, weighting feels artificial and numb.

What this means is that the NX 300h F Sport is a joy to manoeuvre around town at low speeds, but is found lacking when the speedo climbs and the roads get a bit twisty.

Likewise, a stab of the throttle is met with a spike in revs and engine noise as the powertrain switches from its electric motor to internal combustion engine, but the expected thrust-burst never comes.

CVTs are generally tuned for better fuel economy, not a sporting drive, so it makes sense that the NX is a little more hesitant and lethargic to get up to speed, but the transmission does suffer from that ‘elastic’ feel where it can be slow to ‘shift up’ if it thinks you are wanting a sporty drive.

However, these shortcomings are especially evident when stacking it up next to the new Toyota RAV4 hybrid.

The NX is underpinned by Toyota’s MC platform, shared with the old RAV4, whereas the fifth-generation mid-size SUV that launched in 2019 is updated with a TNGA platform.

Much of our aforementioned criticisms in driving dynamics and snoozy drivetrain are fixed, or at least alleviated, in the latest Toyota RAV4, so here’s hoping the next-gen NX rumoured to break cover soon will be a welcomed step forward.

And while the current Lexus NX is certainly not the last world in SUV driving dynamics, it’s not trying to be.

As a daily runabout for the family, the NX is comfortable and predictable – just what some families might be after.

The suspension does a great job at soaking up road imperfections and little bumps you might find on your journey, helped by the comfy seats and great interior sound insulation.

What is noticeable though, is overcoming large bumps or any change in elevation at speed, where the NX 300h’s hefty weight means it takes just a touch longer to get settled again.

The cabin also feels a bit fussy from the driver’s seat, with the multimedia especially being fiddly and hard to navigate when on the move.

We reckon a rotary controller like those found on a BMW, or even better multimedia software as seen with a Benz, could go a long way in fixing Lexus’ multimedia woes.

Having said that, the system is compatible with Android Auto, and is laid out well on the widescreen, so you could easily forgo the annoying touchpad and janky software for a better experience.

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.

Like all new Lexus vehicles, the NX 300h F Sport comes with a four-year/100,000km warranty, along with roadside assist over the same period. A six-year anti-corrosion is also part of the aftersales assurance package.

Scheduled service intervals are every 12 months/15,000km, whichever comes first.

The first three years/45,000km of scheduled servicing is capped at $495 for each annual service, which falls under the brand’s Encore service that also entails pickup and delivery of the NX, loan car, and wash and vacuum.

Lexus ownership also means owners will be access to exclusive events, dinners and drive days, as well as promotions from partner hotels.

Although servicing costs are relatively cheap for the first three years, Lexus’ four-year/100,000km lags behind luxury brand leaders Mercedes-Benz and Genesis, who both offer five-years/unlimited kilometre assurances.

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.
