BMW M240I vs Nissan Z

What's the difference?

With a six-cylinder sweetheart of an engine and a thrilling drive experience on offer, there are some seriously good reasons to consider the BMW M240i. But there are a couple of question marks over some of the finer details - none of them are deal-breakers, however.

So, back to the preposition I plotted at the beginning - does it make sense as a more affordable alternative to the M2? The answer is yes... but it's also, no.

I'd spend the extra money and get the M2, but power and presence matters more to me than it might to most. And then again, I'd probably buy a manual M2 Pure, which is not as far a stretch.

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.

From most angles the M240i looks fairly sporty, which is precisely the requirements for a driver-oriented two-door car. The styling of the body lends itself to the rear-drive underpinnings, with short overhangs at the front and the rear - but to my eye, it still looks a bit funny side-on, where the bubble top gives away its hatchback heritage (it's based on the 1 Series hatch).

New for the 2018 model are adaptive LED headlights, new L-shaped LED tail-lights, re-sculpted bumpers front and rear, and a new set of 18-inch wheels. On the whole, I think the appeal and appearance of the 2 Series coupe is getting better with age - a bit like a scrawny teen, it's slowly growing into its clothes. I guess that's what happens when you have a muscle man like the M2 for a big brother.

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?

What is perhaps the most peculiar thing about the 2 Series Coupe range is that from the back seat it feels almost more spacious than in the 1 Series hatch. Odd, right? And the access to the second row - by way of a pair of folding-and-electronic-sliding seats - is reasonably easy unless you're a plus-size adult.

If you do find yourself in that category, there's a good chance you won't want to be finding yourself in the back seats very often, as there isn't a whole lot of space - anyone pushing 183cm (six-foot) will find their hair brushing the head-lining and their knees bumping the seat ahead. There are only two seats, but they would be well suited to children or occasional adult use.

Up front is BMW’s 'Navigation System Professional' is standard in the M240i, with its large 8.8-inch screen offering touch capability as well as the clever dial controller between the front seats. The system has the new 'iDrive 6' software, just like you'll find in the new 5 series, and there is Apple CarPlay, which is cable-free in this iteration, but BMW asks buyers to pay $623 for the privilege.

The multimedia system also includes BMW ConnectedDrive capability, with emergency calling if you happen to have an accident, and real-time traffic information. When I was driving in to the office, I was alerted of a particularly bad snarl caused by a break-down, which I wouldn't have known otherwise. Clever! And the M240i has a 12-speaker harman/kardon surround sound system, which is good - but not great.

The red leather trim of our test car mightn't be to all tastes, but it certainly is eye-catching, and the quality of the 'Dakota' trim (I always wonder, was that the name of the cow(s)?) is excellent quality. There are front seat heaters, too. Height-adjustable seat belts would be nice, as would seat belt presenters - it's a bit of a reach back to retrieve your clicker, particularly for shorter drivers.

There is good storage on offer, with large enough door pockets for a bottle, though they aren't sculpted as such. There are cupholders in the front, but not in the back - between the two seats is a small storage tray, and there's no flip-down centre armrest between those rear positions, either.

The boot is a sizeable 390 litres, 30 litres larger than the 1 Series hatch, and because there isn't a spare wheel (the 2 Series, like all BMWs, uses run-flat tyres, and tyre pressure monitoring is fitted) there is no penalty to pay for boot depth. The rear seats fold down by way of triggers mounted in the cargo area, but if the headrests have been up on the back seats, they may snag when you drop them down.

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…

Nismo is short for Nissan Motorsport. It’s like what AMG means to Mercedes or HSV was to Holden. Which means, of course, that Australians love this sort of thing.

Last year, as limited editions, the first 100 Z Nismos sold out in under an hour, according to Nissan. Now it’s back more permanently, still from $94,000 before on-road costs, but without quite the exclusivity.

But, don’t worry. You still get the Nismo body kit and leather/Alcantara-clad cabin treatments, stronger performance and track-focused chassis upgrades, which include extra bracing, sharper steering, beefier suspension, bigger brakes and GT-R-spec wider wheels, compared to the regular Z. More on the engineering changes later on.

There are also Recaro sports seats, Nismo-branded digital instrumentation and steering wheel, additional drive modes and red trim highlights.

These come above the regular Z items like keyless entry/start, an 8.0-inch touchscreen, surround-view reverse camera, (wired-only) Apple CarPlay/Android Auto, Bluetooth connectivity, an eight-speaker Bose premium audio, active noise cancellation tech, dual-zone climate control, artificially amplified exhaust note and wider-yet-lighter 19-inch alloy wheels.

Note, however, that going Recaros means ditching the regular Z’s seat heating and electric adjustment including lumbar support. And there’s no spare wheel in either grade… just a tyre-repair kit. Boo.

For your $100K-driveaway, from an equipment perspective anyway, the Nismo does stretch the value argument almost to breaking point, so it’s a good thing that the Z still looks so good. And there’s lots of beautiful engineering underneath that pretty skin too.

The 3.0-litre turbocharged six-cylinder engine is good for a stonking 250kW of power and 500Nm of torque, which is well good for a car of this size. So good, in fact, that BMW claims a 0-100km/h sprint time of 4.6 seconds - just 0.3sec slower than the M2. Sounds like money well saved - you'd have to spend quite a bit more on other German coupes to get this sort of performance.

Shifting gears is an eight-speed automatic with a sport mode, manual mode and paddles, with drive being sent to the rear wheels.

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?

BMW claims fuel use of 7.1 litres per 100km, with emissions rated at 163g/km. I didn't quite get that, with my mix of highway, stop-start and spirited steering returning a consumption number of 8.1L/100km. I'm going to call that better than fair, considering the grunt on offer.

You'll need 52 litres of 95 RON premium unleaded to fill the tank.

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.

If you want to feel on edge, you really ought to take a no-holds-barred spin in the BMW M240i. I mean, ideally, you'd want a closed road or a race track - but a quiet twisty road could be enough to entice your inner enthusiast.

The 3.0-litre turbo six is superb, with plenty of push - you've got to keep an eye on the instruments to make sure you're not moving too quickly: it's that fast. What a shame that those outside of the car get to hear more of it than those in the cabin, though: there is a nice chortle and some crackle on the overrun, but you only get to really hear that if you have the windows down, or you're standing to the side as the car drives past you.

The automatic transmission can be a little tentative in its most sedate mode, but the paddles can fix that, allowing you to bounce off the rev limiter without overriding your choices, bad as they may be.

No doubt this is a brilliant driver's car.

It has staggered width Michelin Pilot Super Sport tyres - 225/40 up front and 245/35 at the rear - around the 18-inch wheels (7.5-inch at the front, 8.0-inch at the rear), but to be honest it could do with even more at the back, because when the engine's 500Nm of torque comes on from 1520rpm all the way up to 4500rpm, you'll be asking a lot of those rear rubbers to keep a grip on the road.

The traction control system does a decent job of keeping things under control - if that's what you want - but the Sport+ setting allows a bit more slip at the back, making for a pretty fun experience in corners. The brake pedal is a little soft under foot, but pulls the car up pretty well.

The adaptive M suspension is changeable based on the drive mode chosen, with Sport and Sport+ setting the chassis up for corner carving over comfort, while Comfort is, er, more comfortable. That isn't to say it is plush, with the rear-end in particular still offering some abrupt reactions to sharp-edged bumps.

No doubt this is a brilliant driver's car - one you won't find the limits of, nor appreciate the abilities of, unless you find yourself on a race track or a closed road. But it also doubles as an amenable commuter, dealing with the droll days of driving to and from work without much hassle at all.

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.

There is no Euro NCAP or ANCAP crash-test rating for the Nissan Z Nismo

Standard safety features include AEB with pedestrian detection (though no operating parameters could be found about this system), 'Predictive Forward Collision Warning', lane departure warning, blind spot warning, rear cross-traffic alert, high beam assist, tyre pressure monitoring sensor, traffic sign recognition and adaptive cruise control with full-stop (but no resume) functionality.

What’s missing? There is no active lane-keep assist tech to nudge you into line, and you won't find parking sensors nor a front-centre airbag.

But the Z does have dual frontal, side chest and head-protecting airbags, a surround-view camera, anti-lock brakes with electronic brake-force distribution and brake assist, stability control, traction control, hill-start assist, front and rear parking sensors, LED headlights with light sensitivity and rain-detecting wipers.

There is also a child seat tether point on the passenger seat, but the Nismo ditches the other Z’s ISOFIX alternative.

BMW's standard warranty program spans three years/unlimited kilometres, with the same period of cover for roadside assistance. There's a basic five-year/80,000km service plan available for $1340, which covers annual vehicle checks, oil changes, filters and plugs, and labour costs. The car's condition-based service system will tell you when it thinks it needs maintenance.

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.
