Mercedes-Benz EQS vs Lexus ES350

What's the difference?

It’s unquestionably fast, certainly luxurious, but I’ll be honest, I don’t think the EQS is going to be for everyone. The styling will be challenging for some and the glittery interior tech offering might be a bit much, even for the more rusted-on Benz traditionalists.

Then again, shouldn't an electrified flagship be all about challenging the status quo, trying new ideas, and bringing new fans to the brand? If anything, I think that might be what the EQS does best.

The ES300h is outstanding in terms of ride comfort, refinement and value. If you’re looking for a true driver’s car then a Lexus RCF is probably a better tree to bark up, but if you’re looking to ferry passengers in a serene, prestigious and fuel-efficient way, then look no further.

We’re going to start with design, because from the outset it is a topic which simply must be addressed.

Mercedes has flipped the script when it comes to its next-generation design language worn by its dedicated range of ‘EQ’ electric cars. It follows a trend we’re seeing across the industry of larger, more amorphous vehicles which need the space to accommodate batteries, but also the aerodynamic traits to extend driving range and keep energy efficiency as high as possible.

The issue when it comes to the EQS is it essentially puts the iconic S-Class shape, refined over generations, in the bin, and replaces it with something a bit more challenging to the eye.

Gone are the angles, louvres, and deeply three-dimensional grilles, replaced by sleek rounded edges, wheels which reach to the very edges of the chassis, a blank, almost plasticky grille and a more liftback-like profile than one of a traditional sedan.

You’d better get used to it, too, because the smaller EQE is near identical in shape, a trend which will no doubt continue across other EQ models.

It’s the finer details that add character, particularly for the 53 with its AMG-leanings. The lack of shapeliness down the side makes the massive 22-inch wheels stand out more, and the rear three-quarter might be this car’s best angle, with a colour-matching spoiler flicking up off the small bootlid, and delicate badgework illustrating this car’s place in the world. Our car, which appeared in a silver shade timeless on Mercedes-Benz models, made the black AMG highlights on the front and rear bumpers shine, and some of the usual Benz shape is claimed back through the EQS’s LED light profile, both at the front and rear.

There’s no doubt it’s a step into the future, and an overall shape which is a marriage of both form and function. While looks are always subjective, I still think it may be a hard sell, even to some of the most committed fans of Mercedes design.

If you think all Lexus models look the same, then pop on over to the Audi, BMW or Benz websites and take a peek at their line-ups. Compared to the ranges from those prestige car makers, Lexus models look wildly different from each other.

Opinions on that ‘Spindle Grille’ are as polarising as views on politics or religion. Personally, I like how upfront and brave the grille design is, but what seems odd to me is that it’s almost as if this was the only place on the exterior where designers were allowed to be a bit adventurous. The rear, while cleanly styled is a bit plain. The bottom just doesn’t match the face.

The ES300h’s roofline in side profile is beautiful as it sweeps almost fastback-style to the boot lid. Again, not the most dramatic styling, but it’s still pleasing in the sense that the design flows well together. The same can be said for the fit and finish – the panel gaps are near-perfect.

This perfection continues into the cabin, where the materials and craftsmanship matches German prestige rivals in places (the door handles, leather and digital instrument cluster, for example), only to be let down in other areas which disclose its budget Toyota family connection (the air vents, steering wheel and display screen).

The ES300h’s interior design isn’t going to set everybody’s world on fire, but there will be those who adore its asymmetrical styling with different textured surfaces that fold, swoop and jut up against each other’s space. Have a look at the images, they’re of the Sports Luxury which sits above the Luxury in the two grade line-up.

The differences visually between the grades is minimal. The Luxury has 17-inch alloys, while the Sport Luxury has 18-inch.

New colours for this generation include Glacial Ecru (the sandy hue of our test car in the images) and Radiata Green. Both grades’ interiors come in a variety of colour schemes, including Black, Chateau, and Topaz. Exclusively for the Sport Luxury cabin is Rich Cream, too. The Sports Luxury steering wheel has wood trim.

One of the more peculiar design elements of the ES300h’s cabin design, and there are a few, are the controls for the drive modes and traction control. They sit like horns on the instrument cluster hood, as though these are things the driver will constantly be reaching for, when in reality most people will never touch the traction control button.

A new-generation car means new foundations, and the ES300h is built on the GA-K platform which underpins the Camry. The platform is part of the latest global architecture which Toyota and Lexus are now using to build its vehicles.

The dimensions of the ES300h, if you’re wondering if it will fit in your garage, are just under 5.0m long, 1.9m wide and 1.4m tall.

The EQS is enormous, so it’s a good thing there’s huge amounts of interior space, even for what is ostensibly an S-Class, and with its bespoke electrified underpinnings, it also scores the kinds of innovations we like to see from electric cars.

These include things like a huge cutaway under the floating dash for extra storage, which the brand has seen fit to add elastic tie-downs so your objects don’t go flying in corners!

Storage up front is otherwise excellent with decent bins in the doors with height-limited sections for bottles, a flip open tray which houses the wireless charger and a set of fold-away bottle holders, and split-opening armrest console box which is deep and features yet another set of USB-C outlets.

Adjustability is great for front passengers, but ergonomically I found something a little weird about the digital dash. For me to rest my arms and hold the wheel, I had to set it so low the top of the wheel obscured the instruments, and if I set it high enough to see the full cluster, to comfortably hold the wheel my elbows would need to float above the armrests. Weird.

It doesn’t end there for the entirely touch-based controls either. While the (admittedly very cool-looking) wheel is packed full of buttons and touch sliders, they require near-surgical precision to operate with your thumbs, distracting while you’re driving, and the enormous centre screen’s main drawback is the fact CarPlay, for example, was not designed for the buttons and functions on the far left to be a metre away from where the driver’s hand is. Again, it’s distracting to have to lean out of your seat to hit the ‘back’ button on most context menus.

I would like to tell you at this point the Mercedes-Benz menus are mercifully simple to aid you with such an overwhelming system, but this isn’t true either. For some reason, there’s a ‘vehicle settings’ menu accessed easily through the main panel, or another menu with a separate set of key functions activated by a car-shaped shortcut button on the floating console. Why? Why aren’t these menus the same? I discovered this in my attempts to use the ‘raise vehicle’ function when faced with a steep driveway. You’re going to need to use this function often in a car measuring over 5.2 metres long, so hiding it in a confusing menu is an interesting choice.

The back seat is where the EQS should shine, and in terms of space it’s stellar. I can barely touch the seat in front of me when set to my own (182cm tall) driving position. It comes with some soft pillows which attach to the headrests, the sunroof extends back there nicely while not impeding on the great headroom, and the lavish trims all continue into the doors and seat bases, too.

The drop-down armrest has a trick pop-out bottle holder in it, and there are a further two on the doors. Amenity-wise rear passengers score four adjustable air vents with two climate zones adjusted via their own touch-panel, but I was interested to see there was a lack of screens back there.

This is particularly notable as most S-Classes are bought to be driven in rather than to drive, and the screens are so much in the front, I was expecting a matching offering for rear travellers. Not so.

You also can’t adjust the rear seats at all, and unlike some EVs coming out in this space, there’s no recliner mode for the full business-class experience.

The boot is much larger than in the smaller EQE, with the EQS making use of its extended dimensions nicely. The floor is fully flat, and has a secret compartment underneath for the storage of both your included Type 2 to Type 2 public AC charging cable, and Type 2 to wall-socket converter for garage charging.

With a total space of 580 litres, the EQS comfortably consumed our entire CarsGuide luggage set with space to spare.

The Lexus ES300h is a five-seater sedan, but it’s really designed to sit two comfortably in the back, given there’s a large driveshaft hump in the floor and that the outboard seats are divided by a fold-down control panel/armrest.

Legroom in the second row is ample. I’m 191cm tall, and I had about 20mm of space between my knees and the seat back when it was in my driving position. Headroom gets tight with that sloping roofline, but there’s just enough space thanks to the low hip point of the rear seats.

Cabin storage is excellent. The fold-down armrest for the rear seats has a storage tray and two cup holders, while the large centre console bin has a lid which can open towards the driver and also to the front passenger (I spent way too long marvelling at how it worked). There are two cup holders up front and decent-sized door pockets, too. Those rear doors open wide for easy exit and entry.

Boot space in the ES300h is 454 litres (VDA), beating the 410-litre cargo capacity of the BMW 530e.

As far as power outlets, you’ll find two USB chargers in the centre console storage bin and a Qi wireless charging pad, which is awkwardly situated making it hard to place larger phones onto it.

Yes, and don’t let anybody tell you any differently. The Luxury lists for $59,888 and the Sports Luxury is $74,888. Both are bargains when you consider the quality and features.

If it was my money, I’d go for the Luxury which is almost indistinguishable visually but doesn’t come with as many tech and convenience features as the Sport Luxury.

Still, the Luxury gets the 12.3-inch screen with sat nav, a 10-speaker Pioneer stereo system with digital radio, a head-up display, dual-zone climate control, wireless charging, 10-way power adjustable front seats, privacy rear windows, a moonroof, proximity key and LED headlights.

The Sports Luxury takes all of that and adds a Mark Levinson 17-speaker sound system, leather seats, heated and ventilated 12-way power adjustable front seats, heated and power reclining rear seats, three-zone climate control, heated steering wheel, power rear sunshade and manual side rear window shades, gesture-open boot and cornering LED headlights.

The Sports Luxury also comes with noise reducing 18-inch wheels – they contain what’s called a Helmholtz resonator which cancels out the drone that can be produced when driving.

Is there anything missing? When I saw the rear fold-down armrest with the control panel I instantly thought the ES300h must have had seat-back screens, but nope. Also, it’s annoying that Lexus still doesn’t have Apple CarPlay and Android Auto as part of its package. This will change we hear, but it has been slow on the uptake.

The Lexus ES300h’s direct rival is the Infiniti Q70 Hybrid GT Premium for $82,900, but it also challenges the likes of Mercedes-Benz E-Class, which starts at $91,900, BMW’s 5 Series, which begins at $92,990, and the Audi A6, which kicks off at $81,900.

Given that the ES300h is hybrid-only, if you’re specifically looking for something with a petrol-electric powertrain, then there’s the BMW 530e or the Mercedes-Benz E350e.

In the electric era, do performance figures matter? AMG would argue a resounding ‘yes’ although I would argue the art for premium automakers like Mercedes is now in producing suspension setups that can handle the weight of batteries.

Regardless, the EQS has a dual-motor setup, capable of providing a whopping 484kW/950Nm in its standard form, or an even more incredible 560kW/1020Nm with the Dynamic Plus package. Look, you’re spending over $328,000 already, what’s an extra $8k or so to put pretty much any other four-wheeled object in your rear-vision mirror? With the Dynamic Package, a sprint time of 3.4 seconds is… brutal.

The four-wheel drive system is necessary to keep all that power under control. While some enthusiasts may be turned-off by the four-wheel steer function, I’d read on to the driving section to see why it’s not only worth having (try turning a 5.2-meter long sedan around without it) but also not as intrusive as you think it’s going to be in the corners.

As mentioned at the start of this review, in Australia the Lexus ES is only available with one powertrain variant – a petrol-electric hybrid.

This combines a 2.5-litre four-cylinder petrol engine making 131kW and 221Nm, with an electric motor that has an output of 88kW and 202Nm. The 244.8V nickel-metal hydride battery has been moved from under the boot floor in the previous generation car to under the rear seats, so it no longer eats into the cargo space.

The ES300h isn’t a plug-in hybrid, so battery recharging is done through regenerative braking.

A continuously variable transmission means seamless and smooth low-speed driving using just the motor, but under heavy acceleration the engine activates and you’ll hear that drone associated with CVTs.

Even at the official energy consumption of 23kWh/100km, the EQS’ drivetrain is essentially the electric equivalent of wielding a massive V8 under the hood. It’s not by any measure impressive, but then, with 107.8kWh of lithium batteries under the floor, it’s perhaps impressive it’s not worse than an Audi e-tron, particularly since the EQS weighs in at nearly three tonnes.

The battery is one of the largest on the market in Australia, offering the EQS a driving range of 585km on the WLTP cycle. Very impressive.

On the charging front, the EQS can charge at up to 200kW on DC thanks to an advanced cooling system, and on AC charges at 11kW in its stock form or 22kW with an optional $2490 upgrade. Again, at $328k, why wouldn’t you want the best charging system you can get for so little extra?

You can also package in a Mercedes-Benz branded wallbox for your home garage, valued at $1450 before installation costs.

To give you an idea of charging times: Expect a little over two hours (from 10 per cent) on a common 50kW DC public charger, nearly ten hours from an 11kW AC public charger, and a number not even worth mentioning from a home wall socket.

This is the point of a hybrid, right? To save fuel? The electric motor can power the car at low speeds around car parks or in bumper-to-bumper traffic, and I found that after 104km of both urban and open road usage my fuel economy in the Sport Luxury was 5.4L/100km.

Lexus’ official combined fuel economy figure for both the Luxury and Sports Luxury is 4.6L/100km.

The EQS is quite surreal to drive, and you’ll notice a whole bunch of odd things first.

Immediately the driving position will be surprising. It’s nothing like what a traditional sedan feels like. This is because you sit high in the EQS. This helps facilitate extra under-floor space for the batteries, but the way Benz puts it, this driving position is deliberately SUV-like to grant buyers the more desirable view of the road which they now (apparently) seek.

It has some oddities, as mentioned earlier, with the fixed digital instrument cluster, and the way the wheel can block it depending on your height, but on the whole I found visibility in the EQS to be pretty good, despite limitations out the distant rear window.

Sound-wise AMG has created a bespoke soundscape for its electric models, two soundscapes, in fact. One sounds like a facsimile of a distant, digitised, V8 (weird) while the other is a bit more sci-fi. I can’t decide which one I really like, but props to the brand for thinking of individual sounds for things like accelerating, regenerative braking, as well as turning the car off and on. There’s even a humming tone for when the car is idling. 

AMG says “it doesn’t work without sound” and I suppose it does add some sort of feedback to the experience which would otherwise be missing. I’d rather have it than not I suppose is the take-away here.

The acceleration is completely over-the-top in Sport or Sport+, allowing you to move such a large vehicle forward in an almost comically quick fashion. It has the sudden urge of a Tesla, but with an element of grace that follows courtesy of the adaptive suspension which, not only settles the ride, but keeps the car comfortable.

It is the suspension though which sets cars like the EQS (and even rivals from BMW) apart from the likes of Tesla. The ride in the EQS is superb, befitting the heir apparent to the S-Class throne. It’s hard to find a ride so void of issues, particularly in the everyday Comfort drive-mode. It’s not just the fact I can’t complain about brutality from this car’s oversized 22-inch wheels, but also there has clearly been delicate work conducted to control the rebound, body-roll, and jiggle which can occur as a result of moving around a near-three-tonne chunk of aluminium, steel, lithium and leather at enthusiastic speeds.

This settled ride combines gloriously with the four-wheel steer system to make the EQS a keen corner carver, despite gravity constantly working against it.

I was surprised to find the four-wheel steer system to be pretty much identical in feel to the system also employed in the EQE and new C43, in that it is unobtrusive to the overall feel of the car, only helping to add a little extra turn-in to the corners when need be.

In a vehicle as long as the EQS it’s a bit more noticeable, and requires a moment of brain-adjustment, as the car (bizarrely) goes exactly where you point it, requiring no over- or under-adjustments, the grip from the enormously capable four-wheel drive system refusing to let any shift under sensible driving conditions. 

So, it’s comfortable enough to be an S-Class, fast enough to be an AMG, but I must say there is something a bit clinical about how it attacks the road. Missing some of theAMG drama we’ve become so used to from the brand’s combustion range, perhaps?

Two words: quiet and comfortable. Well that’s three words, but that sums up the ES300h on the road. Yes, rivals may have intelligent adaptive air suspension and leather made from free range cows, and they are supremely tranquil and sumptuous places, but challenging them is this ES300h.

Even with its regular shock absorbers and steel-spring suspension, the ride was outstanding for its comfort and composure on the worst roads Sydney could throw at it over the week we tested the car.

Front and rear seats were supportive and comfortable over long distances, too. From a driver’s perspective the experience was serene – this was an easy and relaxing car to pilot.

I’m not a huge fan of petrol-electric hybrid powertrains, but it suits the seamless personality of the ES perfectly, adding to the smoothness of the ride as it slipped silently through traffic.

Just don’t expect the ES300h to be rewarding from a dynamic driving perspective. The steering was heavy and a little numb, and while the handling was good, I felt disconnected from the road. And whenever I needed to move quickly the combustion engine would splutter to life and the CVT would begin to drone.

The Lexus ES300h was awarded the maximum five-star ANCAP rating when it was tested in September 2018. Coming standard on both the Luxury and Sports Luxury grades are 10 airbags, AEB with pedestrian detection, lane keeping assistance and adaptive cruise control.

By stepping up to the Sports Luxury you’ll also get adaptive high beams which is fair enough, but you’ll also gain equipment which really should be on the base grade, too, such as blind spot warning and rear cross-traffic alert - which come standard on a Camry SL for half the price.

While there’s absolutely no doubt the ES300h is safe, it lags behind in autonomous technology which is present in cars such as the E-Class.

You’ll find two ISOFIX mounts and three top-tether anchor points across the second row which we used for our four year old and his car seat.

Like many electric cars, the warranty on the EQS is twofold. Firstly, there is the whole vehicle warranty, which from Mercedes-Benz is five years and unlimited kilometres, but the high-voltage battery is covered by a separate, and quite healthy, ten-year, 250,000km promise.

Benz throws in a three-year subscription to ChargeFox, offering owners free charging for the duration (to give you an idea, it cost me about $30 to charge the EQS to nearly full from 20 or so per cent).

Service intervals are surprisingly standard, at 12 months and 15,000km, and the EQS’ pre-paid service program is $1750 for three years, $2750 for four years, or $3250 for five-years, working out to about $650 a year. Far from the cheapest we’ve seen for an EV, but chump change for owners considering the up-front cost of this vehicle.

The ES300h is covered by Lexus’ four-year/100,000km warranty. Servicing is recommended every 15,000km or 12 months. There is no capped-price servicing scheme.
