Maserati Quattroporte vs MG Im6

What's the difference?

Beauty is way more than skin-deep in the Quattroporte and while the 330 doesn't have the punch of the S, it's hardly that much slower. Maserati reasons you will want to spend the $25,000 saved on options, concentrating on the Italian craftsmanship rather than the outright performance available in the V8 or the efficiency of the less aurally attractive diesel.

As with any car of this type, you've got to want one in the first place, but for a big, beautiful sedan, there's nothing as good looking this side of an Aston Rapide. The Quattroporte 330 does nothing to dim the allure of Modena's big mover and, if you're that way inclined, nobody on the outside will ever know.

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.

Long, flowing lines mark out the Maserati as something quite different to its German, British and Japanese competition. This Quattroporte has increased in every dimension but the lines cover its size beautifully.

Big wheels, long wheelbase, low ride but it still looks like a sedan rather than pretending to be a coupe.

The elegance of the lines is complemented by a distinct lack of bling – there's little in the way of chrome work or shouty details. There's plenty satin finishes available and the beautiful paint, while available in pretty much any colour you like, is best kept to a restrained, deep hue. Or silver.

The cabin will doubtless age well. Classic shapes house a fairly conventional but hugely comfortable cabin. The front seats have heaps of adjustment and are large but supportive. Naturally, the leather is soft and supple.

The central screen isn't the dominant feature, like a 50-inch LCD screen in a small living room while buttons are kept to a minimum.

The rear seat is sensationally comfortable, with hectares of available space and a seat comfortable for either lounging or working.

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.

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.

Like the S, the 330bhp is powered by Maserati's twin turbo 3.0 litre V6, made with more than a dash of Ferrari involvement. As the name suggests, it produces 243kW and a chunky 500Nm. With just under two tonnes to shift, the ubiquitous eight-speed ZF automatic transmission whisks the Quattroporte 100km/h in 5.6 seconds, only half a second down on the 301kW V6 S.

Maserati claims 9.1L/100km on the combined cycle (with the help of stop-start), which seems reasonable given our figure of 10.8L/100km, which we got a with a mix of city and highway running as well as a very enthusiastic blast through some secret back roads.

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.

Just a few hundred metres behind the wheel is all it will take to convince you the Maserati belongs in the same class as the competition. It's incredibly quiet – courtesy of the acoustic double glazing – and all occupants benefit from supreme comfort.

While the 330 is 58kW down on the full fat V6, you won't really miss them. There's a fat torque curve, with all 500Nm available from 1750 to 5000rpm, meaning easy progress for the 5.2 metre sedan.

The Quattroporte has two sport buttons to choose from – one looks after the drivetrain and exhaust valving while the second stiffens up the Skyhook suspension.

With the first sport button pressed, you get a more lively throttle, sharper shifts and a glorious noise from the exhausts, although they are a long way from your ears.

It's still a fast car, with strong acceleration from standstill and in the gears, the power as linear as you like with no real turbo lag and a most un-turbo noise to go with the performance.

The only dynamic problem is the electric steering – it seems to get confused between your inputs and feedback from the road, the tyres feeling like they're 'nibbling' an uneven surface, tweaking the wheel in your hands. 

The assistance is a little spotty, too, unexpectedly changing weight. It's just a bit weird. In normal driving, you'll never notice it.

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.
