Nissan Z vs BMW Z Models

What's the difference?

The Nismo turns up the wick just enough to justify its $20K premium over the brilliant regular Z.

Visual changes inside and out are one thing, but with tangible boosts in performance, handling and braking – with no detriment to ride quality or comfort – as a result of properly engineered upgrades, the RZ34 version deserves its place in Nissan’s sports car hall of fame.

Note, though, that good as it is, the Nismo is also a potent reminder of how solid a foundation the standard Z also is… especially in manual gearbox guise.

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.

Reinterpreting a classic via retro styling isn’t always successful – hello, 2001 Ford Thunderbird ­– but what Nissan has achieved with the RZ34, given it’s a pastiche of several Z greatest hits from the ‘70s, ‘80s, ‘90s and today, is truly masterful design.

Take the cab-backward silhouette, long nose and short wheelbase; it somehow manages to deftly capture the spirit of previous Z generations, without looking like a bad caricature.

Points especially go to the stunning nose and tail treatments that evoke both the ‘70s 240/260/280 as well as the sadly long-forgotten Mid-4 II concept car of 1987.

Slightly longer than the regular model, the Nismo’s nose is meant to evoke the early ‘70s Japan domestic market Fairlady ZG, with the G denoting “Grand Nose”. Fun fact: Fairlady first appeared on the 1960 Datsun roadster as deference to the Broadway musical (and later Audrey Hepburn film, presumably) ‘My Fair Lady’.

Anyway, besides scraping speed humps and driveways, the Nismo’s elongated front bumper promotes improved engine cooling and better aero flow, as do the side sills, larger wraparound three-piece spoiler and redesigned rear bumper/diffuser. The wider-yet-lighter back wheels are 10mm wider. And a glossy red stripe runs along the underside like Anna Nicole Smith’s lipstick.

Does it all look better than the simpler, purer regular Z? No. But they perform better. And isn’t that the point of a Nismo?

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.

So, just as the exterior is an anthology of past Z car stylings, the same also applies inside.

A mishmash of new and old as well, they also marry together harmoniously – after you’ve bent and contorted yourself inside nice and snug, on the racy yet not-too-unforgiving set of Recaro bucket seats.

The Z’s signature sloping roof and rising window line; a trio of dials that have been a hallmark of the series since the 240Z, a thin three-spoke steering wheel; a physical hand brake and a pair of old-school seat base angle adjuster knobs just like in sports cars from 20 years ago betray the Nissan’s ageing DNA.

But they set the mood, like hearing a favourite old track, though one remixed by a contemporary DJ to a modern beat.

Which means that you’ll be able to view whichever artist you like through the 8.0-inch touchscreen, either via Bluetooth audio streaming, Spotify or some such app.

Easy to decipher and simple to navigate (though no imbedded GPS is fitted), the Z’s dashboard also offers the essential surround-view parking camera (given how limited vision is as you’re sat so low with not much glass to peer out through), amongst a host of vehicle functions. You’re also privy to extremely useful blind-spot alert thoughtfully placed inside the car by the mirror mounts, four cupholders if you count the door-sited ones and surprisingly generous storage. Practicality, thy name is Fairlady.

For lightness and sensible packaging, we understand why Nissan’s sports coupe is strictly a two-seater proposition – and certainly a roomy enough one for the lucky pair at that.

However, it’s a shame Nissan doesn’t offer a 2+2-seater option in the form of a pair of occasional jump seats behind, as per the old Datsun days, as there seems to be just enough space for smaller folk – though as a pair of shelves, that area did prove very useful during our week with the Nismo.

Issues? Along with a sheer lack of grace entering and exiting the Z, poor overall vision and 350Z-era switchgear that are now old enough to drive themselves, finding the right driving position eluded this particular 178cm tester. The seats do a great job keeping you firmly fixed in place, and of course the wheel tilts and telescopes, but those pair of knobs were forever being twirled and fiddled with.

Oh, and simultaneously unlocking and opening the doors was also confounding, due to exterior door handles and pressure sensor not designed for Homo Sapien hands.

Further back, and as in the two previous generations Zeds, a brace bisects the luggage area. Rated at 241 litres VDA, it is wide and flat but a wee bit shallow. At least it adds another level of practicality and is big enough for those weekends away.

There’s no cover (though seeing what’s inside isn’t easy) and no spare wheel of any size is fitted.

Meanwhile, on the other side of the Nismo…

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.

Nissan sure knows how to make a great six-cylinder engine.

The Nismo’s internal combustion engine in question is the VR30DDTT – a twin-turbo V6 making four per cent more power and around 10 per cent more torque compared to the one found in the regular Z.

Power jumps 11kW and torque a handier 45Nm to 309kW @ 6400rpm and 520Nm between 2000rpm and 5200rpm respectively, providing extra punch as well as a slightly superior power-to-weight ratio of around 184kW per tonne.

That’s up 2kW/tonne, despite the Nismo gaining around 50 kilos, to 1680kg.

This has been possible thanks to extra turbo boost, revised ignition timing, improved cooling systems and updated engine management software.

Driving the rear wheels is a Mercedes-Benz based nine-speed torque-converter auto. Upgraded and retuned for track use, it includes a Sport+ mode providing speedier shift responses. Aided by the new launch control function, we managed a tidy 4.5 seconds from standstill to 100km/h.

Sadly, though, there’s no manual option as per the regular Z.

What else is unique here? Underneath, the platform might date all the way back to the 350Z of 2003, but Nismo has really worked some of its magic.

Along with the retuned dampers, everything else has been stiffened up – including the anti-roll bars, springs, bushes and even the steering rack mounts – to help deliver more controlled and linear steering. There’s extra underfloor bracing at the front, centre and rear of the car, thicker brake rotors and model-specific Dunlop SP Sport Maxx GT600 tyres that are wider at the back, on gloss-black RAYS alloys.

Continuing to use a double-wishbone front and multi-link rear suspension set-up, the Z’s front/rear weight distribution is 56/44 front/rear.

Now, the Nismo was our favourite version of the previous 370Z by some margin. How does it all square up in RZ34 guise?

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.

Not surprisingly, the Z Nismo needs to drink from the 98 RON premium unleaded petrol fountain.

Nissan reckons owners should expect to average 10.4L/100km (for 242 grams per kilometre of carbon dioxide emissions) on the combined cycle (and 15.0 and 7.7 L/100km for the urban and extra-urban ratings respectively.

This figure is almost half a litre worse than the non-Nismo Z’s 9.8L/100km result, but still substantially better than the six-speed manual base grade’s 10.8L, despite the latter being some 33kg lighter.

With a sizeable 62L tank, you might be able to average just under 600km between refills.

For the record, we achieved 11.9 litres per 100km in a mix of urban, freeway and performance driving which is not too bad at all given how often we fanged this thing.

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.

Nissan does plenty of things really well, and the Nismo is no exception.

Firing up the VR30DDTT 3.0-litre twin-turbo V6 is also a reminder of how brilliant the brand’s six-cylinder engines are. They tingle all the right sensory areas, starting with the baritone rumble at idle.

What a portent of what’s to come!

Nismo’s massaging of the engine, combined with upgraded clutch packs and a retune of the nine-speed auto’s software, results in stronger, hungrier and angrier acceleration, no matter which of the three driving modes you’ve selected. Even in Normal, the Nissan leaps off the line. In Sport, its appetite for speed is palpable. In Sport+, this thing is eating up the tarmac. Somehow, in an EV era where 4.5s to 100 is ho-hum, the (electronically enhanced but who cares) guttural exhaust bellow seems to amplify the action and thrills.

And spills. For five of our seven days together, the heavens poured. Now, in Normal mode, the Nismo was as benign and controlled as you’d hope in wet conditions, the driver-assist tech metering out just enough torque and braking to seamlessly keep the car humming along. Ever-present but always nuanced, they’ll help make your commute a safer and more relaxing one.

Selecting Sport loosened things up markedly, with the driver needing to be ready to counteract with steering, seating and throttle, though still with a safety net to keep the car from going totally out of whack; Sport+, meanwhile, is not for amateurs or the distracted. This is serious, tail-wagging waywardness that should only be fully explored with experience and care.

Later in the week, Launch Mode in Sport+ on cold but dry bitumen also requires super concentration, as we discovered attempting to extract the fastest acceleration time. Sideways in a straight line at 100km/h-plus is not for the faint hearted.

Beyond all-out performance and drama, the Nismo soars with weighty yet linear and precise steering, resulting in satisfying, hunkered-down handling that is the hallmark of a great sports car. Really tight turns can be taken at impressive speeds, but there’s about 1.7 tonne of muscle to manipulate, so the real fun can be found blasting along a snaking set of more open corners, where the Z’s inherent thrust, poise and grip come into play, all to the symphony of that bi-turbo V6.

That the suspension can feel both firm and supple at the same time is another arrow in the Nismo’s bow.

Nissan isn’t pretending this is anything but a rousing and rapid grand tourer with track aspirations, so the fact there’s also comfort and sophistication to be enjoyed just shows the sheer bandwidth of this particular Z.

Downsides? There’s always a wall of sound, be it mechanical or noise intrusion from the rubber and/or bitumen. The Nismo is rarely quiet. The extended front spoiler seems to summon up speed humps and bumps you never knew existed. The adaptive cruise control’s inability to resume in heavy stop/start traffic betrays this car’s 350Z-era tech. And the lack of a manual transmission, we reckon, is a missed opportunity for an even greater degree of interactive sports car driving.

Still, the Nismo delivers exactly what the brand promises, and continues to improve a firm favourite for speed and drama.

But the gap between Nismo and regular model is smaller than the one that existed in the preceding 370Z, which means that – if $100K driveaway is too steep – you’re already driving something elevated in the standard Z. Particularly if you yearn for a manual.

It’s all good.

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. 

Your wallet’s pretty secure as well.

Like all Zs, the Nismo is subject to a warranty period of five years with unlimited kilometres, while service intervals are fixed at every 12 months or 10,000km – whichever occurs first. There is also five years of roadside assistance.

Nissan also provides pre-paid maintenance plans that can save up to $245 over three years, as well as capped-price servicing. At the time of publishing, the capped-price service appointments cost between $347 and $950 depending on the year of ownership.

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.
