Mercedes-Benz EQC vs Mercedes-Benz EQS

What's the difference?

When I was telling my colleagues about the Mercedes-Benz EQC my summary was, basically, it’s the best electric luxury car I’ve driven. 

It’s plusher than a Jaguar i-Pace, more polished than a Tesla Model X - indeed, it feels like a different kind of electric car to both of those models. It’s an impressive foray into the segment, and we can’t wait for the chance to put it against some like-minded electric European luxury SUVs at some point in the future.

Does electrification enhance the seven-seat SUV experience? In the case of the EQS450, the answer is yes. Smoother, quieter and with plenty of easy-flowing power, the brand's family-focused luxury electric SUV behaves exactly as you might expect.

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

The Mercedes-Benz EQC is entirely different to what we expect from the brand, but it’s really what we expected all along when it came to an electric SUV from the Daimler stable.

It is sleek, streamlined and smooth, with panels that almost look like they’re formed from liquid. And it has the eco-edgy graphics you’d expect, with a specific grille treatment (yes, a real grille), headlights that are unlike any other Benz (they even have an LED that runs the width of the grille), and a rear-end style that looks almost like it was penned with another Stuttgart-based brand in mind… Porsche. I’m talking about Porsche.

But one thing that I really love about the EQC is its moustache. It's more prominent when the car is finished in white paint, but there’s a moustache that former Daimler chief Dieter Zetsche himself could be envious of. And he had one helluva soup strainer.

It is clearly made to be slippery, despite essentially sharing its underpinnings with the more conventionally angular - yet still rounded-edged - GLC SUV.

While it is a nicely styled gizmo, I found there are some things that could be annoying.

For instance, I was trying to plug in at night in a dark area, and while there is a small light above the charge port, other EVs have a light that actually illuminates the area where you’re plugging in. 

And also, the plug port is on the driver’s side. If, like me, you had to charge up with the car on the street, it just adds a little bit more anxiety to the whole situation. I shudder to think what could happen if the charger was hit by a passing car - folding the mirrors in is one thing, but you can’t fold the power cable! The lead for the charger is long, thankfully. 

I know, most people (maybe even all people!) who buy and EQC are going to have undercover parking in a garage or carport, but it’s still worth remembering that the filler isn’t on the kerb side like a number of other EVs. 

It has almost identical dimensions to that car: 4774mm long on a 2873mm wheelbase, with a width of 1884mm and a height of 1622mm. For context, GLC is 4669mm long, same wheelbase, a bit wider (1890mm) and just a little more height (1639mm).

What about interior design? Well it’s also familiarly different, with a number of changes to the materials used but still the same tech and comfort you’d expect. Check out the interior images in the section below.

It’s a handsome SUV, and one that’s not immediately recognisable as electric — especially given there are little exhaust-pipe-mirroring design flourishes at the rear which make you look twice.

Aussie-spec cars get the AMG exterior treatment, which includes AMG alloys, aluminium-look side steps and the power-domed bonnet, but there's still nothing overly 'shouty' about the design, with the sleek, smooth body panels (accentuated by the hidden handles) making the EQS450 look smaller than it actually is.

Inside, it’s a super-comfy space to spend time, and the little fluffy pillows attached to the headrests should be standard in every car. The tech on offer is ample, too.

But it does all feel a little gigantic, with great swathes of wood panelling and massive screens, all of which make you feel bit like you’ve been shrunken down and are now living amongst the giants.

If you’re thinking the EQC looks like a seven-seat SUV, you’re wrong. It’s a five-seater, with a decent sized boot, too.

The luggage capacity is 500 litres, which is decent for a car of this size, but bear in mind there is no spare wheel under the boot floor. 

Rear seat space is reasonably spacious for someone my size (182cm) sitting behind their own driving position, with decent knee and toe space. Headroom is not terrific, though, and anyone taller will need to watch their head as they get in and out of the car as the top sill eats into space quite a bit. 

Any middle-seat passengers might find the room a little less likeable, as the transmission tunnel intrudes quite a bit. Those with big feet might find shoehorning themselves in and out a bit of a challenge as the sills are quite large, and our car even had optional ($1200) “aluminium-look running boards with rubber studs” - side steps, essentially. They get in the way, too.

But if you’re just sitting two abreast in the back the seat comfort is really good, the trim quality is excellent, and there is a flip down armrest with the storage bin and pop out cupholders. There are rear air vents (no climate control adjustment in the back, though, and no USB charging either), and there are two map pockets, plus bottle holders in the doors. Up front you will find a mix of familiar elements if you’ve sat in any recent Benz model, but a few unique finishes and trim elements that might be new to you.

There’s a beautiful horizontal fin theme that runs around the cabin, as well as the now-traditionally audacious looking Burmester sound system speaker covers. They don’t quite gel with the aesthetic, to my eye. 

The dash-top material - “fine surface texture”, as Benz calls it - is unlike anything else we’ve seen from the brand, it’s kind of like a soft silky slippery fabric trim. While there are lovely copper trim elements that just add something visually entertaining and appealing to the space.

There is a large covered centre console bin with 2x USB-C charge points and there is an additional USB-C upfront next to the wireless phone charger. The Mercedes touchpad system that aligns with the MBUX media screen is reasonably easy to get used to, but being a Benz there are plenty of options for usability - the centre screen is a touch-capacitive unit, or you can use the steering wheel-mounted controller on the left side of the wheel to control the middle screen. The right thumb controller manages the driver info screen.

It was mostly very easily managed, although the menus did get stuck at times for me - mainly in the section around the energy consumption. Plus I tried the whole “Hey, Mercedes” command thing, and it failed on numerous occasions. 

The EQS450 stretches 5136mm in length, 1965mm in width and 1718mm in height. That's about the size of a Nissan Patrol and long enough to make it a proper seven-seater.

The middle row can be adjusted forwards or backwards, and with the front seat set to my 175cm driving position, I found I had ample head and knee room to get comfortable.

USB-A charge points abound, and there's wireless device charging, and because of the sheer size of the cabin, the storage options are plentiful. The central bin between the front seats, for example, seems styled on the Grand Canyon.

In the third row, though, things get a little tighter, but it’s perfectly good for kids. My knees were touching the seat in front, however, and it still requires some acrobatics to climb into.

At the rear, with all three seats in place, you'll find 245L of room (measured to the ceiling), growing to a maximum 1030L with the third row flat. Stow the second row, and you'll find a maximum 2020L of storage space – which, and take my word for it – is plenty.

One small quirk, though. While the second row is electric, stowing away at the touch of a button, the third row isn't. That means, when it's flat, you have to climb into the boot to pull it back up, or attack it from the rear door. Either way, it's more awkward than it needs to be.

Arguably the biggest hurdle the EQS450 has to clear is its asking price, which is a considerable $194,900, before on-road costs.

Inside, you'll find leather seats and trim, a big 12.8-inch central display (and a head-up display), a 12.3-inch digital instrument display, a Burmester sound system with 15 speakers, a panoramic sunroof and cooling and heating in the front seats.

Outside, there are 21-inch alloys, flush-fitting door handles, illuminated running boards and LED lighting, which Benz calls 'Digital Lighting', and offers 1.3m pixels of light per headlight.

The EQC has a power output of 300kW and it has 760Nm of torque, which is enough to see its claimed 0-100km/h acceleration pegged at just 5.1 seconds.

The EQC’s top speed is 180km/h (limited for the sake of the batteries), and it has an 80kWh lithium-ion battery pack.

It uses a pair of asynchronous motors - one front, one rear - and they can alternate to do what’s best in the situation - be it working in 2WD (RWD or FWD), or in AWD. 

If you’re thinking about an EQC as a towing option, the towing capacity is 750kg for an un-braked trailer and 1800kg for a braked trailer.

There are two electric motors delivering the driving power, one at the front axle and one at the rear, which will deliver a combined 265kW and 800Nm, fed through a single-speed transmission and with all four wheels being powered.

That's enough for a sprint to 100km/h of 6.0 seconds.

With an 80kWh battery pack and a Type 2 CCS plug (up to AC 7.4kW / DC 110kW) the charge times vary pretty greatly depending on what output you’re powering up from.

Mercedes-Benz says a DC fast charging station should be able to replenish the battery bank in 1 hour 22 minutes (at a maximum of 110kW, though some Chargefox stations offer charge rates up to 350kW) while an AC charging station (like you’d find in car parks) or Mercedes-Benz’s own Wallbox system should take about 12 hours 13 minutes.

Charging from a regular household powerpoint is a last resort option. It is claimed to take 46 hours 40 minutes from empty to full (230-volt outlet, 10-amp/2.3kW). I plugged in to a powerpoint in my house and the car’s info display was stating it would take 9.5 hours to achieve the remaining 16 per cent of charge. It didn’t get to 100 per cent before I had to unplug, however.

My not-so-urban test drive loop commenced with 97 per cent of battery charge and an indicated range of 363km available. The idea was to get a feel for the “range vs reality” of the situation, so I did it in Comfort drive mode with the climate control active and no intent to either thrash the vehicle or baby it to save battery.

My drive ended with 36 per cent indicated charge remaining, after I’d covered 231.6km. That means, based on the car’s own algorithm, that it would have covered 315km before the battery was depleted, which is a long way short of the claimed 434km range.

The indicated energy consumption was 20.8kWh/100km, which is ‘thirsty’ for an EV. On our recent electric car comparison test, the most efficient of our EVs - the Hyundai Ioniq Electric - used just 13.0kWh/100km. Yes, I know the EQC is a lot heavier (2425kg kerb weight), but even the Tesla Model 3 was notably more efficient (18.5kWh/100km) than the EQC over very similar terrain and driving.

However, our testing saw us return an even better consumption rate than Mercedes-Benz’s claimed figure, which is 21.4kWh/100km.

There's a huge 107.8kWh on board here, but the EQS450's driving range is a less impressive 483km. Maybe something to do with the 2918kg weight of this big SUV.

Don't get me wrong, 483km is plenty to cover almost anyone's weekly commute (and then some), but early promises had pointed to a range of more like 600km.

When it comes time to plug in, you'll find the EQS450 is set up for 200kW DC fast charging, which should see you go from 10 to 80 percent charged in just 31 minutes.

Home charging is, of course, a slower proposition. A three-phase 11kW supply should take 10 hours, while a 7.0kW wallbox will be slower again, and more like 15 hours.

If you have a garage and a Wallbox connector, there’s no reason the Mercedes EQC couldn’t be a terrific option as a commuter, a second car, or even your primary vehicle. 

The thing with all electric cars is that it’s about settling into a rhythm. If you use the car to commute to work, maybe you can charge it there. Or you might have a solar array and charge at home.

No matter the situation, you’ll be getting a rather nice vehicle to live with, based on my week with the EQC.

It’s a plush car, that’s for sure. The silence it offers is truly relaxing, and there’s effortless torque to pull you away from a standstill. The way you can build pace to overtake, the rush of noise-free acceleration, is pretty astounding. Perhaps not as visceral as in a GLC 63 AMG, but it’s still an experience.

The steering is direct and doesn’t require much thought, though it does lack a little bit of feel. But it’s easy to predict and quick to respond, making for pleasant progress around town. It’s easy to park, as well, with a great surround view camera system, as well as front and rear parking sensors. And if you’re not confident, the car has semi-autonomous parking, too.

The brake pedal feel takes some acclimation, because it responds pretty well, but the action is hard to modulate at times. That is partly due to the brake regeneration system, which actively captures energy that would have otherwise been lost during braking. You can adjust the level of aggression of the regen brakes, too, by tapping either the up or down shift paddles. The most aggressive setting will almost pull you up to a halt from urban speed without any brake pressure required.

The suspension of the EQC feels more settled than the last GLC I drove, and that could be in part due to the extra weight and stiffness of the battery cell under the body. The centre of gravity feels low, and it feels stuck down to the road in most situations.

The ride is mostly fine, but with big 20-inch wheels and low profile tyres, it can jar on hard edges. I also noticed that it can feel a bit unsettled at higher speed, as the body moves around - from side to side - more than I would have expected. It deals well with undulation changes and big dips, and if the surface is good, so are the comfort levels in the cabin. 

The drive experience is, well, unremarkable. But I don’t want that to sound negative, because that's not how it's intended.

The EQS450 SUV does exactly what you expect a circa-three-tonne, premium electric SUV to do, and it does it all well.

It's powerful enough without being exhilarating, comfortable enough, and laden with enough tech to satisfy almost anyone.

It's just that it also doesn't exactly ignite the senses. But the question must be asked, what seven-seat family-focused SUV does? Few, if any.

So, surely the real test is if electrification has improved the formula here, and I'd argue that it definitely has.

For one, the EQS450 is properly whisper-quiet in the cabin, with Benz employing multiple sound-deadening techniques at once to lock out road noise. And with no pesky engine to interfere, the cabin is about as serene as they come.

The power delivery is predictably smooth and easy, too. There is no headline-stealing acceleration figure here, but the power is potent and plentiful, and more than enough for any real-world situation you might encounter.

The ride, too, is commendable. Aided by Mercedes' air suspension, it glides over all but the most broken road surfaces. And it is fitted with rear-axle steering, which really does cut down a turning circle that would otherwise surely resemble that of a cruise ship.

It feels heavy at times, though, and even the most high-tech suspension can't eliminate body roll entirely through tighter corners (physics and all that).

But unless you're really pushing – and why would you be – the cabin is calm, comfortable and cosseting.

So, exciting? Not really. But comfortable and calming, which are probably the traits its owners will value much higher.

The EQS450 SUV is yet to be ANCAP crash tested, but you can expect an extensive suite of active safety equipment, including AEB with pedestrian and cyclist detection and junction assist, adaptive cruise control, active lane keep assist, lane change assist and steering assist, traffic sign recognition and eight airbags.

It mightn’t have the same method of propulsion as a petrol or diesel Merc, but it has similar service requirements. You still need to take it to the workshop for maintenance every 12 months - or every 25,000km! - whichever comes first.

Owners can either pay as they go for servicing, or pay up front and bundle it into their finance. The upfront rate is $1350 for three years/75,000km. Pay as you go will peg you along at $450 (year one), $750 (year two), $450 (year three). 

When the EQC launched it came with a three-year/unlimited kilometre warranty plan, but that was recently updated to a five-year/unlimited km plan, bringing Benz inline with the likes of Korean luxury maker Genesis, not to mention the majority of mainstream car brands.

The Mercedes EQS450 is covered by Mercedes-Benz's five-year, unlimited-kilometre warranty, with servicing required every 12 months or 25,000km.

You can prepay your service costs, coming in at $2350 for three years, $3695 for four years or $4280 for five years.

The battery its covered for eight years or 160,000km.
