Nissan 370Z vs BMW Z4

What's the difference?

It's hard not to be ageist when it comes to the current Nissan Zed, because 15 years in market (nine if we're generous) is a lengthy stretch in anyone's book. But somehow the 370Z is more than the sum of its parts. It has fantastic front-engine/rear-drive balance, an increasingly rare atmo engine, and a beautiful manual 'box. The value equation is decent, and it's nicely put together. Just don't expect to be dazzled with the latest safety, driver-assist and multimedia technology.

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.

If you want to go all the way back, the 370Z clearly takes its design direction from Datsun's star of the '70s, the original 240Z.

Inspired by Ferrari, and (along with the Toyota 2000GT) a sports-car breakthrough for the Japanese industry, the first Zed's front-engine, long-nose proportions have remained largely intact in successive iterations over the decades.

With a broad, flat nose, distinctively jagged headlights, and steeply raked rear profile, there's no mistaking the 370's signature stance, with pumped-up guards sitting over fat, 19-inch alloy rims.

Sharp-eyed car-spotters will notice the update's new design RAYS forged wheels, smoked front and rear lights, and a similar smoked finish on the exterior door handles.

A new colour, 'Cherry Red' also replaces 'Bordeaux Black' in an eight-shade colour palette. Our test example was finished in 'Gun Metallic'.

Inside, echoes of Zeds past abound, with a trio of hooded gauges (clock, voltmeter, oil temp) sitting in the centre of the dash top, and the tachometer in the middle of a cowled, three-instrument main cluster shaded by an exaggerated tube.

And aside from consciously retro design touches, some elements have been present inside the car for so long they're just... ancient.

For example, old-school orange graphics for the odometer, gear position and trip computer are dated, and the small (7.0-inch touchscreen) multimedia display has the feel of an early noughties edition of Tekken 6.

Forget a digital speedo or head-up display. A CD slot still sits proudly in the centre stack, and matt silver highlights scattered around the cabin are as on-trend as double denim.

And the steering wheel (joined with the instrument binnacle) adjusts for height, but annoyingly, not reach.

That said, friends and family who rode in the car during the week I had the keys all commented on the swoopy exterior and cozy cockpit feel of the interior. So, what do I know?

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.

Two seats means practicality is a relative term when applied to the 370Z. For example, getting in and out is an athletic exercise requiring gymnastic levels of flexibility and poise. As with most low-lying coupes, I found the outer hand on the A-pillar technique helps with swinging down into the car, or lurching up out of it.

Once ensconced behind the wheel, you're confronted with a relatively modest amount of storage space, running to a medium-size glove box, a lidded bin at the rear of the dividing console, a single cupholder, and door pockets incorporating recesses for small bottles only.

There are two lined recesses for soft bags or coats behind each seat, including a fold-out map pocket, but they're not exactly convenient for retrieving things when you're on the move. What's missing is a tray where you can easily stow things likes keys, coins or a phone.

There are also two 12-volt power outlets, a USB port and an aux-in audio connection.

Rear load space is limited to 195 litres, mainly due to the boot's shallow floor (an alloy space-saver spare sits underneath). It does incorporate a cargo blind and four tie-down hooks, but we only managed to squeeze in the largest (105-litre) suitcase from our three-piece hard set, or a combination of the two smaller ones (35 and 68 litres).

We also had a crack at stuffing in the CarsGuide pram (there is a top-tether hook provided for child seat fitment) and managed it with only a couple of beads of perspiration expended.

Forget the nappy-bag paraphernalia, though. The soft bags with all the baby stuff would have to go in the storage bays in the cabin behind the seats.

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 370Z is powered by an all-alloy, 3.7-litre (VQ37VHR), naturally aspirated, quad-cam V6, producing 245kW at 7000rpm and 363Nm at 5200rpm.

Serving in a vast array of Nissan, Infiniti, Renault and Mitsubishi models, the VQ V6 engine series has been around in various displacements for over 20 years.

It features the 'Continuously Variable Valve Timing Control System' (CVTCS) with 'Variable Valve Event and Lift' (VVEL) on the intake side. And while all that may sound new and ultra-high tech, it was actually introduced in 2007.

Transmission choice is between a seven-speed auto (with manual mode and paddles) or six-speed manual gearbox, as tested here. And this 2018 upgrade brings a high-performance clutch from Japanese specialist Exedy.

Drive goes to the rear wheels via a carbon-fibre composite drive shaft, connecting with a viscous limited slip differential (LSD).

Additional features that won't necessarily be music to purists' ears include 'Active Noise Cancellation', and 'Active Sound Enhancement'.

The former monitors and measures engine sounds, using the audio speakers to produce "acoustically opposing signals to cancel undesirable sounds". So, okay, maybe filtering out the messy noise is a good thing.

But at the same time Active Sound Enhancement employs "digital signal processing to enhance the engine note, using the vehicle's sound system to augment or modify the spectrum of select powertrain sounds in the cabin". Yuck.

I can cop a tube that channels a bit of genuine engine noise into the interior, but in this context, the phrase 'digital signal processing' is a turn-off.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.6L/100km, the 370Z emitting 249g/km of CO2 in the process.

Over roughly 250km of city, suburban and freeway running, we averaged 15.6L/100km, at the bowser. Far from miserly.

Minimum fuel requirement is 95 RON premium unleaded, although Nissan says "for optimum performance" you should stump up for 98 RON. And just to rub it in, you'll need 72 litres of it to fill the tank.

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.

The Nissan 370Z is actually the car many want the Toyobaru 86/BRZ to be. I can sense some of you spluttering out a sweary response to that notion. But hear me out.

If you, like many others, think the 86/BRZ would be perfect with an extra 50kW/80Nm, just bolt on a turbo or supercharger, and voila. You'll get that extra grunt, but remember, the 86/BRZ was conceived to be light, tactile, and, not least of all, affordable.

Up the outputs and you light the wick on an engineering arms race that should also lead to bigger brakes, an engine with more exotic pistons and a tougher bottom end, a stronger gearbox and clutch, a beefier diff, sturdier chassis, fatter rims and rubber... the list goes on, and on. Until you end up with something very much like the spec, weight, and price of the 370Z.

That's not to say this car isn't a fun drive. It is. Just don't expect the quick reflexes of an MX-5 or 86/BRZ.

Despite light-weighting tricks like an aluminium bonnet and all-alloy suspension, the 370Z weighs in at a not inconsiderable 1467kg. And although its 3.7-litre V6 develops a solid 245kW/363Nm, first impressions are dominated by its hollow mid-range.

Much as I love the free-revving nature of a naturally aspirated engine, there's no denying a modern turbo typically delivers lots of torque low down, with peak power also available within a useful rev range.

All the action here is at the top end, with maximum torque arriving way up at 5200rpm, and peak power taking over at a nose-bleed 7000rpm (the rev ceiling is 7500rpm). Not exactly an easily accessible sweet spot.

The gearbox is a sweet reminder of what a pleasure it is swap ratios in a top-notch close-ratio manual.

But there's still so much to like about this evergreen Zed. Its classic front engine/rear-drive layout results in a 53/47 front to rear weight distribution and the car feels balanced and beautifully predictable.

Suspension is double wishbone front, multi-link rear, and ride comfort, even over choppy bitumen surfaces is surprisingly good. On the flip-side, rumble coming up from the Bridgestone Potenza RE050A rubber (245/40 f / 275/35 r) is always noticeable, and often intrusive.

The steering is supported by old-school hydraulic power assist and while connection with the front wheels is impressive, overall feel is light. Hello 'Merica.

The gearbox is a sweet reminder of what a pleasure it is swap ratios in a top-notch close-ratio manual, and hats off to Exedy for producing a wonderfully progressive clutch. Personal preference was to turn off the standard 'SynchroRev Match' function, because I like having a go at the ol' heel 'n' toe tap dance myself.

Brakes are ventilated front and rear with almost equal size rotors (355mm f / 350mm r) clamped by four-piston calipers up front and two piston units at the rear. They are reassuringly powerful and consistent.

Age has not wearied the 370Z's ergonomics. Although the lack of a digital speedo and no reach adjustment for the steering column is annoying, the sports seats are snug and comfortable, the moderately chunky wheel feels great, and all the major controls are simple to use. Who needs slick screens and 'piano black' finishes?

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. 

Nissan offers a three year/100,000km warranty, which isn't exactly ground-breaking in the age of Kia's seven year/unlimited km commitment.

But it does include 24-hour roadside assistance for three years, and Nissan's 'myNissan Service Certainty' capped-price servicing program applies for up to six years/120,000km.

The scheduled maintenance interval is six months/10,000km, with charges ranging from a low of $283, to a high of $831 (100,000km), averaging out to roughly $428 per service.

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.
