BMW 218i vs BMW Z4

What's the difference?

The badge might say one thing, but the 2 Series Gran Coupe sticks to the time-honoured template of being a compact yet comparatively practical three-box, four-door sedan, complete with a big boot.

More importantly, it drives and behaves like a BMW – which means sufficient-to-strident performance depending on grade, athletic dynamics and pleasing refinement on one hand, as well as a stiff price and a hard ride on the other.

A true BMW in name and nature, then..

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.

BMW is calling the F74 a new-generation 2 Series Gran Coupe, and there have been obvious and even profound changes throughout and underneath, including to some of the sheetmetal.

But this is not an all-new car by any stretch, with the glasshouse, doors and roof amongst many other body items carrying over from the F44.

That now remarkably Kia Cerato-esque nose ushers in new LED lighting motifs and an updated kidney grille, but whether they sit easily with the rest of the car is debatable. Redesigned tail-lights, different colours and new alloys make up the majority of the exterior changes.

Betraying the latest 2 Series Gran Coupe’s newness claims are near-identical dimensions, with that redesigned front end and bumpers contributing to a 20mm increase in the F74’s 4546mm length, while revised suspension and damper settings help account for the 25mm boost in height (to 1445mm). The BMW’s 1800mm width and 2670mm wheelbase remain the same.

There’s a higher level of newness to be found inside.

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.

During the media presentation at its launch, BMW described the 2 Series Gran Coupe as being almost as large as a 1990s E46 3 Series, and it is in all major dimensions except wheelbase.

Plus, being a front-drive-biased/transverse engine proposition instead of rear-wheel drive should make it roomier than the F74’s iconic ancestor.

The sense getting in is that this is certainly not too low or cramped as per a more-traditional coupe, with plenty of space for legs and shoulders, while even the optional sunroof fitted to our 218 left us with headroom to spare.

The redesigned dash is a visual and operational treat, with crisp, clear instruments, a logically presented and intuitive centre display screen offering fast and easy operation, excellent ventilation and ample storage. Full marks here.

Better still, attaining the perfect driving position is possible for most people, on brilliantly supportive front seats. This is the stuff BMW does right.

Improvement suggestions for the next update? Some people may complain about the somewhat less-than-premium feel of some of the lower-lying plastic trim; not everybody will love the swatches of colour stitching (we love it); why does the steering wheel have to be so wide-of-rim? Side and rear vision is restricted by fat pillars, rising shoulder lines and a shallow rear window; and there is quite a bit of road noise that enters the cabin at speed.

Still, even the back seat is sufficiently spacious for most users, with the sole exception of taller folk having to negotiate a sloping rear roofline. If you’re below 180cm, this should be fine. Most amenities minus overhead grab handles are also fitted.

Further back, the boot is surprisingly accommodating, with 430 litres of cargo capacity that’s enhanced by a 40:20:40 split-fold backrest, and the aperture should be big enough for bulkier loads, but the lack of a spare wheel will be bad news for many buyers. The supplied tyre-repair kit is just not good enough.

But, you know what is good enough? The engines BMW builds, that’s what.

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.

Three F74 powertrain choices are available for Australia in 2025. And none even remotely reflect what their respective badges imply on the boot.

The 218, for instance, is not powered by a 1.8-litre engine, but BMW’s long-lived B38 1.5-litre three-cylinder turbo petrol unit. Making 115kW of power at 6500rpm and 230Nm of torque between 1500rpm and 4600rpm, drive is channelled to the front wheels via a seven-speed dual-clutch transmission (7DCT).

With a kerb weight of 1420kg, the 218 has a power-to-weight ratio of 81kW per tonne, helping it achieve the 0-100km/h sprint time of 8.6 seconds, on the way to a 230km/h top speed.

Not enough? The 220 features the ubiquitous B48 2.0-litre (not a 2.2-litre) four-cylinder turbo petrol engine/7DCT combo, pumping out 150kW at 6500rpm and 300Nm from 1450-4500rpm. Tipping the scales at 1525kg for 98.4kW/tonne, its 0-100km/h time is 7.3s and top speed is 250km/h.

Want more? Stretching to the M235 xDrive sadly doesn’t mean a 3.5-litre in-line six, but a modified B48 2.0L/7DCT duo, delivering 233kW at 6500rpm and 400Nm from 2000-4500rpm to all four wheels. Result? Weighing just 50kg more than the 220, it boasts a heady 148kW/tonne, for a 0-100km/h of just 4.9s and a 250km/h v-max.

As with all of the UKL2/FAAR transverse-engine front-to-AWD platform models from non-electric Minis through to sub-X3/3 Series BMWs, you’ll find MacPherson-style struts up front and a multi-link independent rear end out back.

If you’re reading this outside of Australia, you may notice that none of the current F74 models offer mild-hybrid tech, in contrast to their European counterparts. And don’t go expecting any manual gearboxes either, unfortunately.

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.

OK, so is the 2 Series Gran Coupe cheap to run?

BMW reckons the 218 and 220 will average 6.3 and 6.7 litres per 100km, which means combined average carbon dioxide emissions ratings of 143 and 152 grams/km respectively.

Filling the 49L fuel tank with 95 RON premium unleaded, that translates to around 775km in the 218, and 730km in the 220 between refills.

Predictably, the M235 xDrive uses more, at 7.7L/100km for a CO2 rating of 176g/km. That’s a distance of about 635km.

Over our launch run, which took us from Sydney’s Circular Quay to Wollongong, the 218’s trip meter was reading in the high 8s and about 10 for the M235.

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.

Earlier, we mentioned that the 2 Series Gran Coupe is way more expensive than fine alternative sedans like the Mazda3 and Toyota Corolla.

And while that still stands, there is a remarkable solidity and refinement difference between those and the BMW that helps justify the premium. And nowhere is this more evident than from behind the wheel.

Sat on body-hugging seats and clutching that (too chunky) steering wheel, there is a sense of sporty occasion, backed up by quality trim and an aroma of expensiveness.

For a turbo three-cylinder car weighing 1.5 tonnes, the 218 does a lot with a little, offering spirited off-the-line acceleration and pleasingly lag-free throttle responses at lower speeds. You’d never call it fast, but it is a quick point-to-point urban mover. Only the unavoidable three-pot thrum lets you know you’re in the lowest mechanical spec. And, also, the delay at freeway speeds in building momentum when overtaking.

Which is why, for less than five per cent extra, the 220 with the 2.0-litre four-cylinder turbo would probably make a better buy. Sadly, that isn’t on sale yet in Australia, so we missed out on driving it during the Sydney launch. But in the scores of other BMWs and Minis we’ve tested this in, it’s a cracking little powertrain.

Whether the big leap (nearly $25K worth) to the M235 is worth it depends on how fast you drive and how much you value/need AWD. This is a terrifically muscular machine, since it provides rapid performance via a tidal wave of power, even with the lightest flex of your right foot. On-point and on-brand, this fun and fiery flagship possesses the grand-touring spirit that the rakish design and tech-heavy engineering promise.

To that end, in both the 218 and M235, the steering makes the driver feel connected to the car, resulting in precise and controlled handling. The driver-assist safety tech is beautifully calibrated and nuanced in its intervention, and the brakes are second-to-none.

What is also on-topic for a BMW is the firm suspension, despite the adaptive dampers fitted as standard equipment.

It isn’t stiff or overly uncomfortable, but bumps are certainly always felt, and they’re accompanied by fairly constant road-noise drone over some surfaces.

As such, you’re constantly reminded that dynamic athleticism is the priority here, rather than sumptuous comfort. We’ve experienced much worse from BMW, but a magic-carpet ride isn’t what’s in store for the 2 Series Gran Coupe owner.

So, what’s our verdict then? The 218 is a rorty little tryer that never fails to involve the driver, while the M235 ushers in an elevated level of acceleration, grunt and grip. We suspect that the 220 will be the Goldilocks-zone happy medium.

For (largely) better as well as for (occasionally) worse, these drive and feel like a BMW should.

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. 

Here, however, is where BMW can do a bit better.

While the five-year/unlimited-kilometre warranty is where most premium brands are, it falls short of several Asian alternatives. Roadside assistance is for just three years and there is no capped-price servicing.

Service scheduling is also condition-based, meaning the vehicle will alert the driver when a service is imminent. This may not suit everybody, and we always recommend at least every 12 months or 10,000km, just to be on the safe side.

BMW does offer pre-paid service packs that take in basic maintenance for the first five years at $2369 or $3782, including brake-pad replacement, which works out to be about $475 and nearly $760 annually respectively. There is also a cap on mileage during that time frame: 80,000km.

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.
