MG Im6 vs Mercedes-Benz Cle200

What's the difference?

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 CLE Coupe really feels like a car of the times. As the electric vehicle market continues to suck in resources, the days of endless variants and body styles is going to wane. But the truth is the CLE does a nice job of filling the demands that both previous C-Class Coupe and E-Class Coupe buyers are looking for.

It’s a stylish model with plenty of technology on the inside, so it should appeal to those who want something refined and elegant for their lifestyle. It has a hint of sportiness on road, without being overtly dynamic or uncomfortable; although Mercedes-AMG will cater to those buyers soon enough. And it offers the kind of space inside that buyers of both models will find acceptable (as long as they don’t have to climb into the back regularly).

The biggest challenge will be convincing C-Class customers to take the big jump up in price over the model it replaces, while at the same time convincing E-Class buyers that this is still something special and different given its similarities to the old model.

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.

Thankfully for the German brand its family look across its range means the CLE seamlessly integrates into both the C-Class and E-Class line-ups.

Mercedes does use some colourful language to describe the looks, with terms like 'sharknose' for the front end, and these ‘powerdomes’ on the bonnet, and there’s a swooping design that wraps around the tail to create a dynamic-looking vehicle.

The biggest question about design, though, is the size of the CLE, specifically how it compares to the two coupes it replaces. While based on the same basic underpinnings as the C-Class sedan, Mercedes has stretched and pulled the body to try and fill the space between it and the old E-Class Coupe.

The result is a car that is 164mm longer than the C-Class Coupe and +15mm longer than the E-Class overall, with the wheelbase stretched 25mm over the C-Class but actually 8mm shorter than the old E-Class two-door. It’s also 50mm wider than the previous C-Class but exactly the same width as the E-Class. So it’s definitely on the bigger size without actually matching up with either model it supersedes. 

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.

Not surprisingly given the exterior growth over the old C-Class Coupe, Mercedes is talking up the increased interior room and practicality. Which is crucial to the success of the CLE because in replacing both the smaller C-Class and larger E-Class coupes, it now needs to appeal to both audiences.

Front seat room is generous, with plenty of shoulder room and the seats offer good comfort and support. In the back Mercedes’ designers have managed to create 95mm more legroom than the old C-Class Coupe, but fractionally less than the E-Class Coupe (just 1mm less). The rear seats are wider than both outgoing models, both across the shoulders and the mid-section. Headroom has been increased by 10mm over the C-Class but decreased by the same amount compared to the E-Class.

Putting the measuring tape aside, while the rear seats are fine for short trips, the back of the CLE is clearly not the place to be and if you plan on using the rear seats regularly then you should be looking at one of the brand’s sedans.

As for the boot, at 420 litres it’s 60 litres bigger than the old C-Class but five litres smaller when compared to the E-Class Coupe; so once again there’s a trade-off between the two.

The initial range consists of just two models - the CLE200 and CLE300 4Matic, but an AMG variant, the CLE53 is due to follow soon (as is the expected-but-not-confirmed V8-powered CLE63), but not before the Cabriolet arrives. While the CLE300 Cabriolet was on hand for us to look at, we weren’t allowed to drive, so we’ll focus this review on the hard-top models.

The CLE200 is priced from $103,900 and the CLE300 is $124,900 (neither price includes on-road costs). While it’s hard to do a like-for-like comparison between the old models and this new one, the CLE is more than $20k more expensive than the old C-Class but around $9-12k cheaper than the equivalent E-Class Coupe.

For future reference, the CLE300 4Matic Cabriolet will be priced from $135,900.

Standard features on both models includes 19-inch alloy wheels, AMG Line exterior and interior packages, a panoramic sunroof, 64-colour ambient cabin lighting, heated front seats with memory function, a head-up display, a 12.3-inch digital instrument display, plus the latest MBUX infotainment system which runs through an 11.9-inch touchscreen as well as Burmester surround sound system. One of the key specification differences between the CLE200 and CLE300, aside from the powertrain, is the interior trim, with the cheaper model using synthetic leather while the more expensive one gets the genuine article.

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.

The CLE200 and CLE300 are both powered by four-cylinder turbocharged petrol engines, albeit in different states of tune, and each assisted by a mild-hybrid integrated starter generator.

The CLE200 Coupé makes 150kW and 320Nm and sends it to the rear wheels via a nine-speed auto transmission. While the CLE300 4Matic Coupé gets 190kW and 400Nm but also gets (as the name gives away) Mercedes’ 4Matic all-wheel-drive system.

While not really a hybrid in the conventional sense, the integrated starter generator adds an extra 17kW/205Nm boost when required while also helping to save fuel.

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.

Make no mistake, the integrated starter generator is a mild-hybrid system, so don’t expect to see miserly returns from the CLE. Instead, the official figures for the pair are quite close, despite the different drivetrains.

The CLE200 has a claimed fuel rating of 7.2L/100km, while the CLE300 uses 7.4L/100km.

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.

To judge the CLE on its driving merits you first need to understand where it fits within the broader Mercedes-Benz line-up. Put simply, while coupes are seen as sporty cars, the German brand has other models that are designed to appeal to driving enthusiasts; such as the upcoming AMG versions of this car and the AMG GT Coupe.

So within that context, the CLE200 and CLE300 do an admirable job of being stylish cruisers that feel at home in the city but not out of place on a winding country road. 

Sports suspension is standard on Australian delivered models, making it 15mm lower than overseas versions and fitted with firmer passive damping too. But still, it doesn’t translate to a dynamically agile and engaging sports coupe suddenly, instead it just gives the CLE a bit more sharpness when turning, at the expense of some comfort on pockmarked roads.

The engines perform nicely, the CLE200 feels adequately endowed with its 150kW/320Nm, so naturally the 190kW/400Nm CLE300 just feels like it has a bit more pep in its step. But I’d question the value of the all-wheel-drive system in a car like this, especially in Australia where the roads are rarely very slippery.

Both CLE models come with all the usual passive and active safety features you’d expect on a modern luxury car, including autonomous emergency braking, ‘Active Lane Keeping Assist’, ‘Active Brake Assist’, blind spot monitoring, traffic sign assist, active cruise control and Mercedes’ ‘Pre-Safe’ accident anticipation system. There’s also a ‘Parking Package’ with 360-degree camera view to keep you and those around you safe at low speeds.

There’s no ANCAP rating for this new model announced yet, but previously both the C-Class Coupe and E-Class Coupe were tested.

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.

The CLE is covered by Mercedes Australia’s usual five-year/unlimited kilometre warranty.

The brand offers pre-purchased service plans for maintenance covering three, four or five years, starting at $3325 then $4535 and then $6800.
