Mercedes-Benz Gls600 vs Audi E-Tron

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 e-tron S looks mean, feels premium, and blends serious power with surprising grace under pressure. I still can’t shake the feeling I had with the standard e-tron, though, that this car is an Audi sports SUV first and an electric car second, and its weight holds it back from being as fun to drive as I think some rivals are.

If you love Audi and you want to go electric without stepping into something too unfamiliar it’s a great option. If you want an electric car which takes full advantage of what the next generation of technology can offer, keep an eye out, there’s plenty of fresh metal on the way.

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 e-tron S looks properly mean, with its adjustable ride-height suspension and enormous wheels combining nicely with the extra subtle sporty highlights to make for a squat SUV which clearly means business.

The width is especially evident with those accentuated wheelarches and the lines set by the lower wing to draw your eyes out to its edges. In profile it's easy to see its long wheelbase and tapered rear roofline, giving even the SUV a slinkier frame than you may be used to when looking at the comparatively boxy Q5.

The thing that strikes me about Audi’s e-tron range, though, is how little a departure it is. It ambiguously slots somewhere above the Q5 and below the Q7, but sticks very closely to the German brand’s styling script.

Sure, it looks a bit lower to the ground, and a bit meaner than you might expect for an EV, but it’s not as much of a departure as Jaguar’s I-Pace or BMW’s iX.

I suppose the biggest advantage here is nobody is going to say the e-tron’s overall visage is controversial, and certainly, it will appeal to existing fans of Audi’s design.

Inside it follows much the same theme, with all the key touchpoints and styling elements nearly identical to other Audis in the range, if not very similar.

It feels like a sensible, refined place in the cabin, with the only whacky pieces being the extra touchscreen for the climate unit and the strange thumb-operated shifter mounted on a floating piece which looks and feels like it could be the throttle control for a jet engine.

The dash is a bit more integrated and modern than in the conservative Q5 or Q7, with the air vents leading to the digital instrument cluster as part of an aesthetic three-terrace design which runs across the entire dash and into the doors.

The screens which appear in place of wing mirrors take a bit of getting used to. Aside from those notable departures, the interior continues the theme of sticking closely to the Audi formula, providing a more modern space which will still be familiar to existing fans of the brand.

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.

As an electric vehicle, the e-tron has certain advantages over its combustion equivalents, and overall makes for an accomplished family-sized SUV. But there are areas where more could be done to take advantage of its high-voltage features and abundant footprint.

Up front in the cabin is a good place, with both occupants treated to lavish seats with plenty of head and legroom, great adjustability, and plenty of width in the cabin.

The finishes are beyond premium with thick chunks of well-padded leather meeting your elbows, hands, and knees at every point. As always the lovely Audi switchgear exists in most places, but the removal of solid toggles and buttons in favour of an extra touch panel feels unnecessary.

There’s still a physical volume knob, and while the climate touchscreen is plenty large enough to have a shortcut button for every function without needing a sub-menu, it feels like you have to move your eyes too far from the road to know you’re going to jab it in the right spot.

Even the main touch panel has an interesting haptic feedback effect for each press, designed to mimic the solidly-sprung button hardware the brand has used in the past.

The screen looks amazing and is fast and sharp, key hallmarks of computer hardware that's up to the task, although the resolution is so high the touch elements when using Apple CarPlay end up being a little small and hard to stab at while you’re trying to keep your eyes on the road.

For storage there’s a big bottle holder and bin in the doors, a large cutaway with a storage tray, dual bottle holders, and power outlets in the centre, with a further smallish storage area under the armrest console.

Unlike some EVs there’s no huge cutaway under what was traditionally considered the transmission tunnel, although there is a small bay with the USB-C ports.

The rear seat feels good for space, with an almost flat floor and decent legroom and width, although headroom could be better.

There are netted pockets on the backs of the front seats and decently-sized bottle holders in the doors, with a further set in the drop-down armrest.

The quad-zone climate with its own touch panel and adjustable centre vents is a nice touch in the rear, as is the set of USB-C ports below. The hard backings to the front seats and built-in sun blinds our car had will even be great for kids.

The boot measures in at 660 litres, which is high for the segment. It fit our three-piece CarsGuide demo luggage set with room to spare, and that's despite the massive battery pack under the floor.

There’s auxiliary storage, too, with a further bay under the boot floor and a second small tray situated under the bonnet, both useful for keeping your charging paraphernalia.

A base, before-on-road costs asking price (MSRP) of $168,400 for the e-tron S in SUV form puts this sporty model a step above two of its most notable rivals, the Mercedes-Benz EQC (currently tops out at $141,300), and Jaguar I-Pace (currently tops out at $155,550), but below the menacing, full-fat BMW iX M60 (at $222,900), or the incoming updated Tesla Model X Plaid ($206,449).

To be fair here, only the iX M60 and Model X are pitched as performance variants in their respective ranges, with the Mercedes and Jaguar lacking either an AMG or SVR model respectively to represent their performance line-ups.

To that end, the e-tron S ups the ante when it comes to its power output with an impressive 370kW/973Nm across three motors, two at the rear, and one at the front. More on this in the Drivetrain part of this review.

Suffice it to say, it’s a lot of power. The e-tron is high-spec across the range, too, with the S scoring massive 21-inch alloy wheels, ‘Valcona’ leather interior trim, a heavily digitised cabin consisting of a 12.3-inch digital instrument cluster, 10.1-inch multimedia touchscreen, and a second 8.6-inch touch panel for the car’s climate functions.

The e-tron S also gets wireless Apple CarPlay and Android Auto connectivity, with matching wireless phone charger, built-in navigation, a 16-speaker Bang and Olufsen sound system, full LED lighting for the head and tail-lights and throughout the cabin, quad-zone climate control, heated front seats with power adjust, and a panoramic sunroof.

Finally, the S also has performance enhancing features like progressive (variable ratio) steering and adaptive air suspension.

Obviously, with the high level of standard gear, there’s not as much to put on the options list, although our car also had the weird $3500 ‘Virtual Exterior Mirrors’ which grant it concept-car like cameras with adjustable touch-panels inside the car in place of standard wing mirrors.

I don’t like these, but Audi says nearly half of all e-tron buyers are choosing them. More on this later.

There’s also the option to upgrade the car’s AC charger from 11kW to 22kW which could be very appealing if you have a public station nearby capable of putting out such power. This option will set you back a further $6900.

The last item on the list is the 'Sensory Package' ($9600) which bundles improved Matrix LED headlights in with soft close doors complete with puddle lamps, extended Nappa leather trim in the cabin, rear sunshades and heated rear seats. Our car had this option pack, too.

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 S-branded e-tron sets itself apart from the rest of the range with a seriously powerful set of three motors. There are two on the rear axle, and one on the front axle.

The total combined output of this collection is 370kW/973Nm, which for a combustion car, would be unprecedented.

To be fair, these figures are under a ‘boost’ mode, with the car generating a still strong 300kW/800Nm in most situations.

The three motor drivetrain allows for an electric version of Audi’s ‘quattro’ all-wheel drive system which the brand says can react to changes in 30 milliseconds and move torque appropriately.

The system is rear-biased, and in the name of efficiency the front motor is only used when required under acceleration or cornering.

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.

The e-tron may be electric, but it’s also a performance car. To that end, its energy consumption, relative to the field, is behind the pace.

In fact, at a whopping 27.8kWh/100km, driving the e-tron around feels like the electric equivalent of steering a big V8.

It produced one of the highest consumption numbers I have seen from any EV during my time with it. Considering this number is even below the WLTP consumption number, which is 28.4kWh/100km, that's not great.

For comparison, the Mercedes-Benz EQC's official number is just 20.8kWh/100km, while the Jaguar I-Pace consumes 21.2kWh/100km according to the WLTP procedure.

Yes, they aren’t performance cars in the same sense, but it’s still a big difference.

I made sure to take it out and stretch the e-tron’s legs to assess its performance in its more sporty driving modes, but the majority of my time with the car was spent in a more comfort-oriented setting and with the regenerative braking set to maximum.

Possibly as a result of its real-world consumption, my car was showing about 350km of range on a full charge, a little below the official WLTP number of 364km, although it is worth noting the enormous 21-inch alloys do their part to reduce the range. The car ships with 20-inch wheels in Europe.

The good news is the e-tron is capable of charging fast, with its max DC charging speed set at 150kW (allowing for a 5.0-80 per cent charge time for its 95kWh battery of 30 minutes), and its AC charging speed set at 11kW, which allows a slow-charging time of around seven hours.

If you intend to park on the street or live in a unit where installing charge infrastructure is impossible, I would strongly recommend you consider the 22kW AC charging upgrade which will cut the AC charge time in half.

While there are few public stations currently capable of the full 22kW in Australia, it will future-proof your car for ideal convenience charging for when they're more commonplace. 

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.

Does the e-tron live up to the promise set by sporty Audis which have come before it? The answer is interesting.

There is no doubt the e-tron S is rapid, at times absurdly so. If you stick it in the required S mode and hunker the suspension down, planting the accelerator makes its claimed 0-100km/h sprint time of 4.5 seconds suddenly very real.

It lurches ahead without so much as a squeak from its enormous tyres, grabbing the road with its front axle as it warps you forward.

So yes, this electric performance car is no doubt quick. It is also heavy. Weighing in at a tare mass of 2830kg, the e-tron S is quite literally massive.

The trouble is, while its powerful electric motors are great at overcoming this gravitational obstacle in a straight line, it’s in the corners and at low speeds where you feel every bit of it.

The e-tron crashes over larger bumps, it’s suspension struggling to deal with the combination of its weight and low-profile tyres, while it can also feel cumbersome in the corners around town.

The suspension is better at levelling things out once you gain a bit of pace, and the tyres work with the all-wheel drive system to put in a Herculean effort when carving up bends at speed, but there’s the ever-present lurch of weight always working against you.

This feeling isn’t helped by the steering tune, which even in its most comfort-oriented setting feels hefty and slow to turn. In the default sport mode, ‘dynamic’, it takes effort to push this car around corners.

Despite the unsettling feeling of it, though, the car holds on for dear life, and I never once felt as though the tyres were remotely in danger of breaking traction when put under pressure.

Is it a performer, then? Absolutely, there’s something mind bending about a vehicle so heavy going so quickly.

Does it feel fun to drive? Less so. I enjoyed the connectivity of the Porsche Taycan offers at speed more than I enjoyed the e-tron S, and its weight and girth demand a nice wide piece of tarmac for you to really wring it.

It’s far from a darty and engaging car like the Q5 can be despite its mammoth power outputs.

Elsewhere, the drive experience feels very Audi, though. The touchpoints and feedback are mostly familiar, as are the software and ergonomics.

The virtual wing mirrors are more of an inconvenience than anything else. This car is already hard to see out of, with big C-pillars and a tall belt line, and the digital exterior mirrors offer what feels like a limited angle of vision and make it extra hard to see out at night.

Some things fall to the wayside a little. The e-tron’s drive system almost hides the regenerative braking setting several menus deep, which, once activated, allows you to set it using the paddle-shifters on the wheel.

Audi says the regen will account for nearly 30 per cent of the car’s range, which is odd because even at the highest setting it feels a bit mild, relying on the user to manually operate the brake for a ‘blended braking’ mode to make up the difference.

It’s a bit of a stretch from the single-pedal driving modes offered on some rival cars.

My theory here, as with this car’s look and feel, is the e-tron is primarily designed to be familiar to an existing Audi customer, or someone coming out of a purely combustion premium rival.

The regular e-tron range is considered very safe by ANCAP which awarded it a maximum five stars with strong scores across all categories in 2019, although it does exclude the S which was not released at the time of testing. 

The S has the same suite of active safety features as the rest of the range, though, which includes freeway-speed auto emergency braking (up to 250km/h) with pedestrian, cyclist detection, and intersection assist, lane departure warning with lane keep assist, blind-spot monitoring with rear cross-traffic alert, adaptive high-beams, adaptive cruise control (with eco-assist and stop-and-go functions), as well as a clear exit warning.

The 360-degree camera suite is welcome, as is airbag coverage for the front, side for both front and rear rows, as well as curtains.

ISOFIX points feature on the rear outboard seats, and there are top tethers across all three rear seats.

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.

Audi has followed its Volkswagen parent in upgrading its warranty to five years and unlimited kilometres, finally leaving BMW and its three-year warranty behind.

The e-tron’s high-voltage battery components are covered by a separate eight-year and 160,000km warranty, but the big win, especially in this premium segment, is the first six years of servicing (covering three 24 monthly or 30,000km visits) is free.

Oh, and your public charging is largely free for the same period too, as Audi throws in a six-year ChargeFox subscription.

Six years pretty much cost-free? Audi, how far you’ve come.
