Mini 3D Hatch vs BMW Z Models

What's the difference?

The Mini 60 Years is another classic special edition Mini and its definitely one for the fans. I'm not at all fussed by it and would quite happily save my money for a standard Cooper S. The Mini is still one of the most playful, interesting cars from a mainstream car maker and while it doesn't please everyone with its size and weight, it's tremendous fun to drive.

It's the kind of car I could own and I always feel comfortable in - it's the perfect size for urban environments but is just as much at home belting down a freeway on a long trip or scooting down a B-road just because.

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.

Always readily identifiable, Mini updates always add detail without touching the main game. I quite like the indicators, which are big LED rings surrounding the headlights, but then again I'm a sucker for lighting. I think the Mini looks terrific in three-door form and the Union Jack rear lights have grown on me. They're a bit silly but in a good way, which kind of sums up the car. The British Racing Green looks pretty good, too. Amusingly, the puddle lamp even has a 60 Years flavour.

You can spot the Cooper S by the centre exhaust and the 60 Years has its own set of 17-inch alloys.

The cabin is pretty much the same apart from the particularly warm hue of the leather. It's a classic colour for British cars but works nicely. In the Cooper S, the panoramic sunroof is split in two, but the front section opens. It does make the car feel a bit bigger, which is handy given it's pretty tight in there. The piping is a nice touch, too, although the Piano Black on the dash was so last decade rather than so last century but at least there isn't a slab of tacky wood. The fact the interior is otherwise unchanged means there are other cheap touches that somehow fail to ruin the ambience.

Mini calls its version of iDrive 'Visual Boost' for some reason, and it's displayed via a 6.5-inch screen set in a big round dial ringed by changeable LED lights.

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.

Yep, it's a small car so expect things to be reasonably cosy. I fit in there fine but I am neither particularly tall nor broad. Taller folks will fit just fine in the front (but not too tall, don't be greedy) while larger people might find themselves uncomfortably close to their passengers.

The rear seat is bearable for children and patient adults on short trips. At least they'll be well hydrated because as well as the pair of cupholders up front there are a further three in the back for a total of five. The Mini joins the NC Mazda MX-5 as a car with a greater cup capacity than passenger capacity. Front seat passengers can keep the water topped up as there are also small bottle holders in the doors.

There are two USB ports in the front seat and a wireless charging pad that doesn't fit bigger phones under the armrest. If your iPhone is the smaller size, the combination of wireless CarPlay and charging pad is excellent.

The boot is surprisingly big for such a small car, beating many of its cheaper rivals with 211 litres with the seats in place and 731L with them folded down.

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 Z4 isn’t cheap, but it plays in a field of expensive Deutsche drop-tops. Our car was the mid-spec 30i which comes in at an MSRP of $104,900 (before on-road costs).

For that you’ll get a more highly tuned version of the base 20i’s four-cylinder turbocharged engine, producing 190kW/400Nm, 19-inch alloy wheels, M Sport brakes, Adaptive M suspension, and adaptive LED headlights.

That’s on top of the already impressively-specified 20i’s kit which includes dual 10.25-inch screens – one for the multimedia functions, the other as a digital dashboard, a head-up display, full Vernasca leather interior trim, auto-dimming rearview mirror, power adjustable and heated front seats with memory function, dual-zone climate control, 10-speaker 205W stereo, a Qi wireless charging pad, and adaptive cruise control as part of a marginally upgraded safety package (more on that in the safety section).

It’s a pretty plush set of equipment, although a challenging value proposition as the almost-as-well-equipped 20i starts from $84,900, a full $20k cheaper.

Rivals for this 30i model? You’ve got the soon-to-be-discontinued Mercedes-Benz SLC300 ($102,500), all-wheel drive Audi TT S quattro ($105,661), and, at a stretch, the entry-level Porsche Boxster ($122,960).

Of course, being a premium European car, there is an extensive options list. Our car was fitted with the excellent and probably-worth-the-money M Sport differential ($2400), as well as the rudely priced M seat belts (literally just the M pattern embroidered in - $560!) and interior ambient lighting package (lovely, perhaps not worth $550).

The Z4 is only offered in five colours, three of which – including our car’s Black Sapphire – come at a cost of $2000. The red interior, surprisingly, is a no-cost option.

If you’re keeping track that brings the car you’re looking at here to $110,410. Not cheap, and it doesn’t have six-cylinders - but given its other attributes explored later in this review, the fact that it still manages to undercut an entry-level Boxster is actually reasonable.

The Cooper S has the usual 2.0-litre turbocharged four (the Cooper has a 1.5-litre turbo three-cylinder), serving up 141kW and 280Nm. Power finds its way to the front wheels via a seven-speed twin-clutch transmission and will push the 1265kg Cooper S to 100km/h in 6.8 seconds.

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.

Mini reckons you'll get 5.6L/100km on the combined cycle. Maybe you could if you don't drive it like I did (I got an indicated figure of 9.4L/100km).

The Mini has stop-start to help cut fuel use around town and launch control to ruin those efforts.

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.

Driving a Mini is a unique experience. Almost no other car on sale today has the combination of that far-away, near-vertical windscreen and an A-pillar that is almost slim by today's standards. The side of the car is almost fifty percent glass, so vision is terrific. 

It had been a little while since I drove a Mini Cooper S so I was looking forward to the Mini bounce that I've always loved and my wife despised. Somewhere along the way, that bounce has faded somewhat, to the point where my wife says she doesn't mind it anymore. That must be a good thing, because while the ride is more refined, it's still a blast to drive, even if you're just getting around in traffic.

The Mini just loves point and squirt driving. The quick, well-weighted steering helps you swing the nose in and out of gaps and the handy slab of torque from the 2.0-litre ensures you stay out of trouble while doing it. The Mini also loves haring down a country road, the more secure-feeling ride belying its short wheelbase. The weight of the car probably helps keep things on the straight and narrow. It's pretty clever to make the car feel grown-up while also maintaining its sense of playfulness.

The driving mode switch doesn't make a huge amount of difference, with Sport mode adding a few apologetic pops from the exhaust.

Complaints are few, but there are too many buttons on the steering wheel and to my mind are all in the wrong place. By necessity, the controller for the media screen is practically on the floor and is crowded in by the cupholders and huge handbrake lever. But that doesn't mean Mini should take away the handbrake.

I have my reasons.

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.

Convertibles and safety don’t often fall in the same sentence, unless its one where a concerned relative is trying to convince you not to buy one.

In any case, the Z4 benefits from four airbags (dual front and dual side), as well as the expected electronic stability controls. That optional M Sport differential will have the added bonus of preventing any unexpected slip and slide at the rear.

On the active side the Z4 gets ‘Driving Assistant’ which includes forward collision warning (FCW), lane departure warning (LDW), rear cross traffic alert (RCTA), and rear collision warning. The 30i grade also gets 'active cruise control with stop & go' which allows for full auto emergency braking (AEB) with pedestrian and cyclist detection. Not on the spec sheet, but apparently present in the car I drove was some form of traffic sign recognition (TSR) and lane keep assist (LKAS).

A nice high-res reversing camera displayed on the massive touchscreen is a welcome standard addition.

Considering the meagre safety specification of most convertible cars, the Z4 30i shines with a half-way decent active safety suite. But you can forget ISOFIX child-seat anchor points. There aren't any. 

As with parent company BMW, Mini only offers a three-year/unlimited kilometre warranty with roadside assist for the duration. You can buy an extension to five or hold your breath during negotiations with a dealer.

Servicing is condition-based - the car will tell you when it needs one. You can buy a servicing package that covers the basics for five years for about $1400 or step up to the near-$4000 option which throws in consumables like brake pads and wiper blades.

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.
