Mercedes-Benz Eqc400 vs MG Im6

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.

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.

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.

I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.

It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.

Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.

And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.

The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.

The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.

Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.

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 IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.

That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.

There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin. 

The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.

There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.

The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.

Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.

There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990

The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.

Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.

There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.

There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.

Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.

Honestly, it’s a lot of stuff, and a lot of tech.

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.

This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.

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.

Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.

Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.

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. 

First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.

But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.

MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.

Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.

The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.

There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.

As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.

The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.

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 IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.
