Mercedes-Benz Gls600 vs Lexus Lm500H

What's the difference?

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.

The Lexus LM 500h is luxurious, comfortable, practical, easy to drive and expensive. While it may appear to be the ultimate family car, with only four seats it's limited in terms of how many kids and their friends you can carry. On top of that, the privacy screen introduces accessibility issues to the kids you wouldn't encounter on other vehicles. If you are thinking of a Lexus people mover as your next family car I'd suggest looking at the LM 350h which has seven seats and no privacy screen. If you’re looking at a business class executive van the LM 500h would be perfect. 

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.

The LM 500h doesn't look real. More like a concept vehicle with its vertical face wearing that enormous grille. Feels like if you watched it for long enough you’d catch it transforming into some kind of robot. Yet, at the same time its styling is elegant and prestigious.

I have a confession to make. I used this Lexus as my office. Its interior is that comfortable and spacious. I'm also a parent and there were times where it was the quietest place to get some work done.

It also let me observe people's reactions as they walked past with their dogs not knowing what was going on inside behind those tinted windows. The people that noticed were clearly car enthusiasts as they knew what they were looking at and couldn't pass without gaping it awe.

The LM 500h’s interior is superbly plush with thick carpets, beautiful copper metallic trim and nappa leather seats.

As I’ve said, the cockpit up front is less luxurious than the extravagant first class section in the back behind that dividing wall.

And yes, I’ve seen large screens before but nothing that stretches the width of the vehicle.

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.

You might be able to take Lexus out of Toyota but it's very hard to take Toyota out of Lexus and this particularly applies to the practicality of the LM 500h.

Every day I discovered new compartments, tray tables and storage areas. There are so many cabinets, lockers and hidey holes that we almost left my belongings (an entire family of plushie toy capybaras) behind because there are so many places to check.

Of course, I'm talking about the rear compartment here because up front there's not much storage. In fact, it proved to be quite a problem in that I had nowhere to put my bag with somebody sitting next to me and no area behind the front seats to stow it, either.

Talking of seats, the LM 500h only has four of them, with two up front and two in the rear. Up front, the seats are supportive and large, but the rear seats - those are, well... have a look at the images.

We’re talking two large captain's chairs that look as though they’ve been removed from the first class section of a plane.

And while this might be suitable for businesses shuttling a couple of executives to and from meetings, for a family, even with two children, the extra couple of seats a third row offers would come in handy.

The LM 350h has seven seats over three rows and no privacy screen. A far better choice for families.

For device charging there are USB ports up front and in the rear. There are wireless phone chargers for those in the back seats but not up front.

The LM 500h has a cargo capacity of 752 litres with all seats in place.

The Lexus LM 500h sits at the top of its range and is without a doubt one of the most expensive people movers on Earth with its list price of $220,888.

As you would imagine the standard features list is as extensive as it is extravagant.

For starters, while the regular LM 350h has two rows of seating in the rear (seven seats all up, including the front two), the 500h has the third row removed and just two super luxurious and enormous fully reclining seats fill the entire space. It’s like a theatre back there.

That theatre theme keeps going with a media screen in the back so large it stretches the width of the vehicle. Seriously, it's a 48-inch screen to watch movies or connect to your device.

The sound system is probably the best I’ve experienced - a spine tinglingly incredible 23-speaker Mark Levinson set-up.

What else can I tell you? Those rear seats are upholstered in beautifully soft semi-aniline leather. They’re heated and ventilated with a massaging function and... ridiculously comfortable.

There’s four-zone climate control, windows which have an electronic shade that turns the glass opaque, there are wireless phone chargers in the doors and carpet throughout so thick you sink down into it as you step inside.

Our LM 500h was upholstered in the 'Solis White' leather which also brings contrasting and mesmerising copper metallic trim.

Oh, and there’s a wall with an electric glass screen that can be raised or lowered to separate the rear passengers from the driver.

I should have mentioned this earlier. The kids loved it, but these parents spent a lot of time telling the 10- and three-year old not to put the screen up again.

The rear occupants, aka the kids, can also lock the screen in place. Which they did, and so sound proof is the dividing wall that we can only just hear their uproarious laughter.

Up front, the cockpit is comfortable but it’s clear all the space and luxury is for those being driven around.

Still, the front seats are leather with heating and ventilation, there’s a 14-inch media screen and 12.4-inch digital instrument cluster, plus a head-up display. Sat nav, Apple CarPlay and Android Auto are also standard.

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 LM 500h is a petrol-electric hybrid with a 2.4-litre four-cylinder turbo-petrol engine which makes 202kW/460Nm and works in concert with two electric motors.

The front motor makes 64kW/292Nm and the rear makes 76kW/169Nm. The combined maximum power output of the two motors and the petrol engine is 273kW.

The LM 500h is all wheel-drive and has a six-speed automatic transmission.

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.

Lexus says after a combination of urban and open roads the LM 500h should use 6.6L/100km. In our own testing we found consumption was higher at 9.4L/100km.

Worth noting my driving environment was mainly a hilly suburban one filled with school drop offs. Achieved some personal bests this week, with one long run to Sydney’s outskirts, only to return in nightmarish peak hour traffic.

Premium (95 RON) fuel is required and the tank size is 60 litres. In theory the driving range is a smidge more than 900km, which drops to around 640km using our real-world average.

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.

Quite simply, driving the LM 500h is like piloting a limousine on stilts. Superbly comfortable, but with an elevated driving position that offers outstanding forward and side visibility, the LM 500h is an easy vehicle to drive for long periods of time.

A digital rear vision mirror means visibility behind is good and unobstructed by the privacy screen or the seats.

The drawbacks are down to the lack of space up front, with the driver’s chair limited in its ability to recline or slide back due to the bulkhead behind it.

And that's compounded by the lack of cabin storage for bags if the front passenger seat is taken.

As for the rear passengers there aren't many people movers offering this level of comfort, except perhaps the Zeekr 009.

Variable suspension that adjusts continuously keeps the vehicle composed and provides a high level of comfort for those in the rear. At the same time, the LM stays nice and flat through roundabouts while remaining civilised over speed bumps.

And then there's the acceleration, which, while not supercar-like is incredibly brisk for a van. The all-wheel drive system provides outstanding traction in wet and slippery conditions, too. 

Our family used the LM daily for everything from school runs to shopping trips and weekends away and not only was it fun to drive, our lucky rear passengers enjoyed sitting high and being able to see clearly out their windows along with the luxury of a giant movie screen.

The Lexus  LM 500h is yet to be tested by ANCAP so it doesn't have a safety assessment score. There is, however, a high level of safety tech onboard including AEB which can detect pedestrians, cyclists, motorcyclists and other vehicles, emergency steering assist, lane keeping assistance, road sign recognition, rear cross-traffic alert, front and rear parking sensors as well as six airbags.

For child seats there are ISOFIX points and top tether anchor mounts on the two rear seats. We have a forward facing child seat and found it easy to install.

A space-saver spare wheel is located under the boot floor.

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.

Lexus covers the LM 500h with a five-year, unlimited kilometre warranty. 

The Lexus Encore Platinum program is complimentary for LM owners for three years, providing 24-hour roadside assist, a loan vehicle or pick-up/return service at service time, 'On Demand' vehicle evaluation options, valet and airport parking benefits as well as exclusive offers and event opportunities.

Servicing is recommended annually or every 15,000 kilometres, and impressively, pricing is capped at $695 per service over five years.
