BMW Z Models vs MG MG QS

What's the difference?

The Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

What it lacks in driving panache it does make up for in terms of space and equipments, and there really is room for seven decent-sized humans on board. Combine that with a decade of warranty coverage, and the MG QS will no doubt be appearing on family shortlists.

The Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

You’re not going to miss the MG on the road, are you? For one, it looks pretty big, and pretty athletic, plus it’s got that bold front-end and grille design that, if I’m honest, I can’t tell if I like, or if it’s over the top. 

Elsewhere, though, it’s more traditional SUV styling, though there is some nice and gentle detailing in the body that makes it look less big, broad, and boring, and the slightly nose-forward design gives the QS something of an athletic stance.

Inside, it’s really quite nice. The twin screens look fantastic – and the subtle curve linking the two looks properly elegant – and there’s some lovely detailing in the through the dash panels, too, which also helps to break up the fact that there is simply a lot of dash here.

As always, I love the row of switches below the screen that act as shortcuts to the functions you need, when you need them, without having to rely on the screen all the time. 

But I'd encourage you to have a good squeeze of all the materials used. Some look like stitched leather, but are actually harder plastics in disguise.

The Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

The MG QS is a smidge under five-metres long, just over 1.9m wide and just under 1.8.m high, which puts it right in the seven-seat SUV ballpark.

That pays dividends in the backseat. I’m 175cm tall, and I had heaps of room to spread out, and I don’t only have my own air vents, but I have my own temperature controls, too.

It’s a big and airy space, and I’d have no problem spending some serious time here on a longer road trip.

But the big question is, what do those dimensions mean for third-row riders, and does it live up to its promise of being a true seven-seater?

Well, yes and no. The fact that the middle row is on rails helps massively, because you can slide it forwards to maximise leg room for backseat riders, and the one-touch entry (which folds the middle row up and forwards) makes actually climbing back there pretty simple, too.

But... it's still a space in which I wouldn't want to spend too much time. Its big enough for shorter trips, but it's still best for the smaller kids in the family.

Now, as is often the case with three-row cars, how much boot space you get very much depends on how many people you have onboard. With all three rows in place, you get a miserly 203L, fold the third row and you get 517L, drop both rows and you get 1052L.

You get introductory national drive-away pricing for the two-grade MG QS range, with the Excite yours for $46,990, and the Essence we’re testing sets you back $50,990 on the road.

In typical MG fashion, neither model is wanting for much in the spec department, but our Essence gets the lot and the kitchen sink.

Outside, there are 21-inch alloys, LED lighting with fog lights, a powered tailgate and a powered sunroof. Inside, there are leather seats which are heated and ventilated up front, tri-zone climate control and ambient interior lighting.

Tech is handled by twin 12.3-inch screens with wireless Apple CarPlay and Android Auto. There’s wireless charging, too, and a 12-speaker Bose stereo.

The top-spec model also gets all-wheel drive, adaptive suspension and six drive modes — Normal, Snow, Off-Road, Sport, Custom and Eco.

There are five exterior colours available on the QS, including Oxford White, Black Pearl, Camden Grey, Regency Green and Cashmere Silver.

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

Under this hood is a 2.0-litre turbocharged petrol four-cylinder engine, which produces 153kW and 360Nm. In this all-wheel-drive Essence, that power is channelled through a nine-speed automatic and sent to all four wheels.

I don’t have a zero to 100km/h time for this two-tonne-plus beast, but suffice it to say it won’t knock your hat off. I’m guesstimating just under 10 seconds.

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

Now MG reckons you will see 8.8L/100km on the combined cycle, which would give you a theoretical driving range of around 738km from its 65-litre fuel tank. For the record, we saw more like 11 litres.

That tank, by the way, demands 95RON fuel, so you won’t be troubling the cheapest pump at your local service station.

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

It all comes down to what you're looking for in your large SUV. Is it a vehicle that – against all odds – manages to somehow stir your emotions from behind the wheel, whether you're flying solo or you're riding with seven on board? Well, the MG QS won't do that.

But if you're looking for something big, comfortable, nicely trimmed and with just about every feature you can think of, then the MG QS ticks those boxes and then some.

But let's start with the not so good. The steering in the MG QS is super, super light, leaving it feeling largely disconnected from what's happening beneath the tyres, and giving the drive experience a weird and artificial vibe.

Now, it must be said that some drivers like that. A big car with light steering makes manoeuvrability easy in car parks and the like. But I don't. It makes me feel uninvolved in the drive experience.

The QS is equipped with Sport mode that does add heft to the steering, but which also appears to make the gearbox way to eager to shift down and hold a lower gear, adding a harshness to the drive.

It's also not a big engine, and this is a big car, and so there's a bit of delay when you first plant your foot as the engine figures out its next move, and you're always aware of the engine working fairly hard to get the QS moving along – though MG has done a good job of deadening much of that sound before it enters the cabin.

But if that's the not-so-good, there are still plenty of ticks in the MG's plus column. It's a largely smooth-riding, sweet-shifting proposition, the QS, and the space in all three rows is impressive, especially when the sliding second row is utilised to maximise the space where you need it.

The MG QS hasn’t yet been crash-tested by ANCAP, but all the expected safety kit is on board, including seven airbags, AEB, rear cross-traffic alert, adaptive cruise control, blind-spot monitoring, lane-keep assist and lane departure warning.

But be warned, it can bing and bong and random intervals. If it thinks you’re speeding, or that you’re not paying attention, and it is very, very annoying. Learn how to switch off the speed limit recognition and driver attention alert, and fast.

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.

It’s a tale of goods and bads in the QS ownership world. The good is a near market-leading 10-year/250,000km warranty (so long as you regularly visit an authorised service centre), and solid service intervals of 12 months or 15,000km, whichever comes first.

The bad is eye-watering service costs – including a whopping $2920 dollar service at the six-year/90,000km mark.

All up, seven years/105,00km of servicing will cost you $6336 in the 2WD, or $6962 in our AWD – the latter averaging out at close to $1000 per year.
