BMW M4 vs Nissan GT-R

What's the difference?

We cannot think of a faster or more invigorating four-seater luxury convertible for the money than the new M4 Competition.

Finally, after years of devastatingly fast droptops with remote steering and an unforgiving ride, the G83 generation discovers refinement and sophistication to go with its supersonic speed.

There’s terrific talent on tap here that no rival can even come close to right now. BMW is on a roll and this is the first M4 convertible that can sit proudly alongside the best of its classic M3 ancestors.

The GT-R of the famous R32 era was a direct response to immortals like the Audi Ur Quattro and Porsche 959 that preceded it in the 1980s.

But the Nissan’s true gift since then is that it has evolved over successive generations, to serve as a glimpse of what these long-discontinued European supercars might be like if they, too, were allowed ongoing development, rather than dropped.

As such, the last R35 GT-R as we know it in Australia is far from disadvantaged, even 15 years on from launch, because it was devised and developed outside of the usual constraints and compromises of mere mass production sports cars.

In 2022, then, the Nissan GT-R remains timeless and transcendental. It’s still an incredibly moving and thrilling driving experience… if you can get hold of one.

Hallelujah! The unloved folding hardtop is history and fabric is back in fashion in a BMW 3/4 Series-based convertible for the first time since the demise of the E46 convertible in 2006.

It improves the proportions and aesthetics out of sight while remaining superbly insulated. It’s also 40 per cent lighter to boot while liberating 80 litres of extra luggage space.

The roof requires just 18 seconds to drop away or erect again, and can be done so at speeds of up to 50km/h. And it looks great, with a taut fit that suits the BMW’s lithe lines to a tee. With all four windows dropped, it also does a fab impression of an American-style pillarless hardtop.

Roof up or down, the M4’s muscular styling has a tense sparseness to it that means business, reinforced by that oversized, M-specific kidney grille treatment that, admittedly, isn’t as divisive in real life. The smiley LED light wave out back also brings a friendlier tone, harmonising handsomely with the rest of the car.

This is probably the best-looking BMW convertible since the beautiful E46 era.

At its 2007 unveiling, R35’s design chief, Shiro Nakamura, revealed to your author that the GT-R had to express modern Japanese culture, singling out the giant robots of the Gundam genre.

It also had to look “mechanical”, something highlighted by the squareness and creases. He also mentioned something about “…withstanding fashion trends throughout its lifetime while evolving with the times”, calling out Porsche’s 911 as inspiration. Clearly the circular tail-lights connect with the Skyline originals of the 1960s.

Some 15 years later, mission accomplished.

Six years in the making and with the design locked in during 2004, the GT-R was nevertheless a global project, overseen by Mr Nakamura but with input from Nissan’s US (mainly the rear quarter view) and UK outposts (roofline). The latter remain as striking as ever.

Despite its blocky visage, the R35 boasts an impressive drag coefficient of 0.26 Cd, aided by particular airflow elements and helping it achieve a 320km/h top speed. While the GT-R’s body consists of steel, aluminium and carbon-fibre to contain kerb weight to a very reasonable 1751kg, the latter also partly makes up the platform, further assisting aero.

Hands down, this is the coolest supercar in the world. 

The M4 Convertible is not a paragon of space efficiency, given its footprint.

At nearly 4.8 metres long and 1.9m wide, the M4 Convertible casts a sizeable shadow on the road, which only really pays dividends for front-seat occupants inside.

Ours was fitted with a very handsome pair of $7500, two-tone M Carbon bucket seats up front, a sort of futuristic tombstone design with a fixed headrest that looks like they were created by and for Stormtroopers; they do provide all the electronic adjustability one would need in terms of fore/aft, up/down and lumbar support movement.

But, unless you really need their g-force-bracing support and love their outrageous appearance, they are monumentally obstructive to effortless entry/egress and overall hip comfort if you don’t possess a gymnast’s physique. In fact, at times, they can feel downright torturous, especially in the gusset area due to the pointless (ironically) hard central bulge bit. The standard front seat set-up is perfectly fine, offering all the comfort and support expected in a luxury convertible, with the added bonus of headrest adjustability.

As with all G20/G80 generation 3/4 Series, the M4’s interior is a welcome return to form for BMW, from the excellent driving position and superb build quality, to thoughtful switchgear placement, brilliant ventilation and ample storage. And iDrive is probably the best and most intuitive multimedia system out there, too, needing no special skill or distraction once mastered.

A quick note about the instrumentation. The 4 Series design digital readouts are prettier than the standard 3 Series' ugly standard screen that looks ex-Honda Civic. This one offers alternative views and is easy to read at a glance. But it still makes us pine for good old analogue dials. Remember when BMWs were the world leaders in dial design?

Some familiarisation is also required to figure out the M part of the M4, including the various driving and performance modes; they’re divided into Road, Sport and Track settings. Yet, thankfully, they’re all far simpler to get your head round than before, which required too much fiddly concentration, since – once quickly learnt – everything is possible with eyes-on-the-road promptness. A new M Mode button offers pre-determined shortcuts to whichever drive combinations are desired.

The roof is well insulated, meaning that previous-gen folding hardtop-owning prospective buyers shouldn’t be too sad about the fabric above their heads. On the go, front occupants can enjoy a variety of configurations, starting with snug coupe-style cosiness and security, moving to cool pillarless hardtop-style windows-only down cruising, to the full top-down convertible glory. The latter also brings minimal buffeting at speed unless you’re stuck out in the back. Roof-up vision isn't brilliant, though.

Strangely, with the M Carbon bucket seat options ticked, it’s actually easier for some people to get into the back than the front. Pulling a strap sees the front bucket seats (slowly) whir as far forward as possible to allow sufficient room for people to clamber onto the rear seats.

Once sat, it’s clear that longer-legged people will struggle. Knee room is OK (especially if the front occupants are feeling sympathetic by moving their seats forward), there’s surprisingly adequate head room for your 178cm tester when slightly slouched, big feet can be tucked beneath the front seats and scalps never have to touch the rear glass thankfully.

And at least BMW has tried to make life back there comfier for smaller people, due to rear-facing air vents with climate and directional control, two USB-C ports, a pair of cupholders, a centre armrest and some handy storage. The materials are of a high quality construction, too.

However, the fixed back rest is far too upright, the knees-up posture quickly gets tiresome, the cushion is firm and you’re sat on a slight angle pointing outwards. Claustrophobics won't be too happy either. Annoyingly there aren’t side window buttons either, meaning only the driver can lower or raise them. The two-seater back seat is best saved for short trips or kids.

Happily, once the roof is dropped, the hemmed-in feel vanishes, there’s not too much wind intrusion or buffeting with the side windows up and there’s a sense of shared freedom that only a four-seater convertible can bring. Going the full drop-top experience will ruffle more than hairdos at freeway speeds, though. An optional wind deflector can fix that issue for front-seat occupants, but it goes over the back seats, turning the M4 into a two-seater ragtop.

Further back, the 300-litre boot isn’t accessible from the cabin, meaning you can’t put much inside at all. BMW fits a hinged flap that needs to be down for the roof to work since it cordons off the roof storage part of the boot when folded in; when lifted, there’s a useful amount of space for luggage, and it’s a handy rectangular shape instead of an L-shaped slot, but obviously at the cost of convertible driving. You can’t have both.

Note that, compared to the previous folding-hardtop M4, this boot is some 80L larger. 

“We could have made the cabin much tighter, like a sports car, but we didn’t, because even though it is one of the fastest cars in the world, at the same time we wanted to make enough space to drive every day.”

Those are Mr Nakamura’s words from 2007 again, highlighting how user-friendly the GT-R’s cabin was designed to be.

Ample, sedan-like space is available up front, so people can get in and not feel cramped or hemmed in at all. This is in keeping with the old three-box Skyline philosophy. Australians can see it in the 1973 Datsun 240K, a distant cousin of the GT-R.

Back to 2022, with its fascia angled slightly to the right and the binnacle moving vertically with the steering column, the Nissan's whole focus is on driver welfare, and so making it a better sports car in the process. Storage is excellent, as is ventilation, while vision out is enhanced by the upright windscreen pillars and acutely rectangular side window shapes that offer their own brutalist ambience.

Just a few years ago, the equally squarish dash would have seemed laughably dated – and some of the details still are – but the physical switchgear feels fresh again after an endless wave of newer models with touchscreens and sub-menus that require fiddly prodding, when a button does the job better. That they’re weighty and mechanical in their operation adds to the GT-R’s mystique.

Being a T-spec, swathes of suede-like material also bring real class to the interior, along with the green-on-green colour scheme, chunky gear lever, thick-rimmed three-spoke wheel, hefty paddle shifters and exacting build quality. Actual 3D dials are lovely to behold as well.

Racy, tombstone-style electrically-actuated front seats, too, rise to the occasion, enveloping their occupants with an inviting sumptuousness that brings both comfort and support for hours on end. They also feature a clever curled knob that deftly takes care of reclining and fore-aft duties in one. Does any other car offer such an item?

Several seasons ago, Nissan overhauled the centre console, cleaning up the intimidatingly complicated switches and simplifying the various, customisable digital readouts that provide deeply intricate accounts of engine, driving, performance and vehicle operation data via arcade-game-like analogue-look dials. It’s really over-the-top techy and yet also mid-2000s cool, and that should thrill the curious teenager in us all. The fact that Polyphony Digital of Gran Turismo video-game fame helped develop all this just makes the R35 all the more cooler.

However, the Nissan parts-bin digital graphics, especially in the multimedia system, betray the GT-R's advancing years, as they’re so obviously steeped firmly in another era. They convey info efficiently, but they’re out of place in such as an exciting, hedonistic machine.

Plus, in keeping with a car that was released the same year the original Apple iPhone was, there’s no adaptive cruise control, digital radio and wireless smartphone charger, let alone Apple CarPlay/Android Auto of any description. But you’ll find Bluetooth connectivity as well as active noise cancellation tech at work in there, along with an 11-speaker audio system of outstanding sound quality, a USB port and... even a plug for your iPod.

Moving out to the rear, there are two seats bisected by a centre console that runs the length of the cabin, providing a natural armrest as well as a drink holder and home for a pair of Bose speakers.

The cushions are comfy enough, as are the well-angled backrests, and an average-sized person like your 178cm tester can rest back there for short periods in relative civility as long as they don’t sit too upright to avoid scalps touching the rear window.

Finally, further back, there’s a pleasingly long, deep and wide boot area, offering 315 litres of richly carpeted cargo capacity. A high loading lip and odd shape limit the amount of luggage you can put inside, however, while there’s no in-cabin access like a ski-port or folding backrests. It’s a separate compartment.   

But, like the rest of the Nissan’s cabin, the GT-R remains appealingly practical for a supercar. As Mr Nakamura said, “…you can use it for daily life, anywhere and anytime.”

To bring you up to date, the current GT-R has had to be discontinued in Australia because it fails to meet a recent Australian Design Rules stipulation that requires older-model new vehicles to be side-impact crash tested.

Don’t fret though, because a redesigned version of the current model is expected sometime in 2024, meaning that the next-generation model – probably dubbed R36 – will continue with an albeit revised version of the brilliant 3.8-litre twin-turbo V6.

More of the same, then. And we’re not complaining.

For Japan’s only mass-production supercar, conventional value-for-money parameters never applied to the R35 GT-R. From $193,800 (all prices are before on-road costs), the 419kW/632Nm, 2.7 seconds to 100km/h and 320km/h entry-level Premium significantly undercuts and outruns esteemed competition like the Porsche 911 Carrera (from $241,200) and Mercedes-AMG GT (from $294,077).

Likewise, if you were canny enough to nab one of the 28 examples of the T-spec imported to Australia (out of only 100 globally) from $256,700, then congratulations; you might double your money selling it right now. Rivals with similar performance include the Aston Martin Vantage from $299,462, BMW M850i xDrive from $285,900, Jaguar F-Type 5.0L V8 R P575 AWD from $270,265 and Porsche 911 Turbo from $404,900.

The T-spec fills the gap between the $199,800 Premium Luxury and 441kW/652Nm Nismo from $378,000; the latter ushers in substantial body, chassis, engine, suspension and braking modifications gleaned from GT3 racing experience, that helps shave 0.2s while boosting V-max by 10km/h. Along with the 911 Turbo, this puts the Nissan in league with the Lamborghini Huracan, BMW M8, Aston Martin DB11, Mercedes-AMG GT R, Ferrari Portofino, Maserati MC20 and McLaren 570S. And that’s before considering the even-lighter SV flagship.

Value, then, is relative.

Soaring resale potential aside, whether the T-spec brings nearly $70,000 worth of enhancement to the GT-R experience is debatable. And nowadays, academic.

As in all grades, you’ll find active torque transfer AWD, adaptive dampers, composite ceramic brakes, selectable driving modes, limited slip differential, gearshift paddles, dual-zone climate control, cruise control, an 8.0-inch multimedia touchscreen with satellite navigation, 11-speaker Bose sound system, keyless entry/push-button start, auto LED headlights, rain-sensing wipers, heated/electric mirrors, Brembo brakes, 20-inch Rays wheels wrapped in Dunlop SP Sport Maxx tyres, a carbon-fibre engine brace, titanium exhaust system, heated and powered front seats and semi-aniline leather applied to the upholstery, steering wheel, gear shifter, dashboard and door trims.

The T-Spec meanwhile, scores Brembo carbon ceramic rotors measuring in at 410mm (up 20mm) and 390mm (up 10mm) front and rear respectively, gold-painted 20-inch alloys and a carbon-fibre spoiler, while a dark green hue, quilt-stitched Alcantara roof lining, suede A-pillar trim and special kick plate finishers complete the interior changes. It also brings back two historic colours from the early-2000s R34 – Midnight Purple and Millennium Jade.

Also redolent of the first decade of the millennium are a distinct lack of modern active and driver-assist safety systems, so you won’t autonomous emergency braking (AEB), lane support systems, blind-spot monitoring or adaptive cruise control. Instead, your lot is limited to six airbags, anti-lock brakes with electronic brake-force distribution and brake assist, stability and traction controls, active cornering headlights, a hill holder, front and rear parking sensors, a reverse camera, tyre-pressure monitors and 20-inch runflat tyres. The latter means no spare wheel is fitted.

Progress does not wait for anybody or anything – even a Japanese supercar from 2007.

Here is a summary of Australian-market outputs and prices for the M3 and M4 convertible autos, with the prices in brackets being approximate inflation-adjusted figures for today.

1999 E36: 236kW/350Nm 3.2L in-line six-cylinder engine (I6), $152,000 ($266,000 in 2022); 2003 E46: 252kW/365Nm 3.2L I6, $158,000 ($240,000); 2008 E93: 309kW/400Nm 4.0L V8, $183,442 ($240,000); 2014 F83: 317kW/550Nm 3.0L twin-turbo I6, $178,430 ($202,000).  

In 2022, the G83 M4 Competition lives up to its name in more ways than one, with a 2993cc 3.0-litre double overhead cam direct-injection twin-turbo I6 known as the S58 series, which is itself derived from BMW’s B58 modular family of engines. Its 375kW is delivered at a lofty 6250rpm, while there’s a 650Nm plateau of torque between 2750rpm and 5500rpm.

A kerb weight of 1920kg means the M4’s power to weight ratio is an impressive 195.3kW/tonne, helping its published 0-100km/h time of 3.7s. For a few grand extra, the company will up the top speed by 30km/h, to 280km/h.

BMW says the engine includes cooling and oil supply systems designed for extreme lateral forces at high speeds, while the exhaust uses electrically controlled flaps for a more raucous noise.

Power is channelled to all four wheels continuously via an eight-speed M Steptronic transmission with a trio of shift programs. The AWD system features an active differential to better transmit torque to all four wheels, while drivers can choose one of three, progressively more rear-wheel drive (RWD) biased modes: 4WD, 4WD Sport and 2WD – the latter being a pure RWD set-up.

Other related changes the M4 boasts over regular 4 Series models include special stability and traction control tuning, a double-joint spring strut front axle with unique axle geometry and variable-ratio steering, a five-link rear axle featuring its own kinematics and elastokinematics, M-specific adaptive dampers, a configurable braking set-up according to feel and response, and forged M light-alloy 19-inch alloys up front and 20-inch items out back.

Choosing the AWD-only convertible over the equivalent AWD coupe adds 145kg (and 195kg compared to the RWD coupe), though this is partly offset in two ways over the preceding, folding-hardtop M4 Convertible: firstly, using the soft top drops weight by 80kg; and secondly, while the AWD system does add 50kg, it’s at a lower centre of gravity, thus naturally improving vehicle dynamics.

Which are electrifying, by the way.

Does it get better than this?

The GT-R’s VR38DETT is already steeped deeply in motoring folklore. it really is one for the ages.

But just in case, here are the salient facts. It's a handmade 3799cc 3.8-litre 90-degree V6, with intercooled twin turbochargers, double overhead cams and variable valve timing, pumping out an incredible 419kW of power at 6800rpm and 632Nm of torque from 3300-5800rpm.

Tipping the scales at an entirely admirable 1751kg (kerb), the GT-R boasts a power-to-weight ratio of 239kW per tonne, helping it scream to 100km/h in 2.7s, on the way to a top speed of 320km/h. There’s a launch control system to help the latter out.

Drive is delivered to all four wheels via a six-speed dual-clutch transmission with a trio of modes depending on the level of performance desired, courtesy of Nissan’s traction and yaw-based ATTESSA AWD system. This features an electro-magnetic clutch and 1.5-way mechanical LSD to shuffle between 50 and 100 percent of torque rearwards. Suspension is double wishbones up front and a multi-link out the back.

Weight distribution to 53/47 front-to-rear.

We managed 12.1 litres per 100km in a mixture of urban, freeway and rural-road driving, including plenty of performance testing. This is a two-tonne M4 convertible capable of supercar speeds, after all. In that context, the economy is more than acceptable. No doubt the stop/start engine function (at idle) helps here.

For the record, the official combined-average claim for this Euro 6-rated BMW is 10.4L/100km, for a carbon dioxide emissions average of 237 grams/km. Thanks to a fuel tank that holds 59 litres of 98 RON premium unleaded petrol, it can manage an average of almost 570km between refills.

Given the Euro 5 emissions-rated GT-R’s prodigious performance, a 15.3 litres per 100km result in a mix of urban, freeway and performance driving is actually not too bad. Again, it's all relative.

Nissan’s claims are 12.0L/100km (and 17.2L/100km and 9.0L/100km for the urban and extra-urban runs respectively), for a carbon dioxide emissions average of 281 grams/km.

A sizeable 74 litres of 98 RON premium unleaded petrol is what the recommended tipple is, allowing over 615km between refills.

Marvellously.

Earlier, we said that the previous M4 (and some earlier M3 generations) never hit the dizzy heights the best like the E46 managed.

The reason why is bandwidth. Not WiFi bandwidth, but rather the newfound breadth of capability that the G83 model has acquired.

Yes, while even the slowest examples of previous M3s and M4s remained thrilling, with blisteringly potent acceleration accompanied by a soaring exhaust soundtrack, the post-E46 models seemed to become almost too obsessed with the pursuit of performance. Thunderous V8s and twin-turbo V6s are all good and well, especially when they provide explosive responses, but there’s more to sports cars than sheer bloody-minded speed.

More specifically, though the handling and roadholding were outstanding, the previous M4’s steering didn’t feel as connected or one with the driver, instead seeming a little remote and detached. Conversely, even with adaptive dampers on offer, the suspension (on Australian roads) lacked sufficient isolation from bumps and thumps, and so was never settled or calm. It was all too nervous and edgy, like a drug-addled athlete who’s indulged in too much partying.

Thankfully, the curse is broken with the latest iteration, even in the heaviest and slowest version like our M4 Convertible as tested, pushing out boundaries to thrilling effect once more.

With the newly-simplified and logically presented M performance modes only a push of a button away, the driver now no-longer has to concentrate on what setting they’re in, and instead just immerse themselves in the experience of accelerating, steering, cornering, braking and controlling this incredible sports convertible.

Tremendously strong in regular Road mode, the M4’s performance certainly lives up to the legend, stepping up into the supercar realm when Sport or Track are chosen, hunkering down as it thrusts towards the horizon with relentless speed and determination, accompanied by the gorgeous twin-turbo six’s revs as they soar towards the red line. The ultra-alert eight-speed auto’s operation is equally seamless, displaying uncanny intuition in its selection of the right ratio at exactly the right time.

These are all incremental improvements over what has come before. But what’s really changed is how rock-solid the BMW feels as it belts along at speed, magnetised to the motorway regardless of weather, its new AWD engineering keeping everything steady and planted. No more tetchiness to unnerve the driver.

Which makes the feel and fluency of the chassis even more remarkable, given that now all four wheels are driven. The very opposite of leaden or inert, the superbly weighted steering is instead light and alive in your palms, as you carve through corners with pin-point precision. Some might find it a bit too eager to change direction at first, but we reckon BMW has judged the balance just right. Its sheer agility is as life-affirming for driving enthusiasts as it is immersive. Bravo, BMW.

With so much grip and control, this is not to say that the driver can’t hang the M4’s tail out every-which-way, since the chassis set-up allows for progressive oversteer, even in Road mode, along with as much drifting as your courage allows where safe. As with the best sports cars, the M4 is as steerable from the seat of your pants as it is using the throttle.

Finally, there’s the M Adaptive chassis tune, that at long last broadens the M4’s repertoire from motorway grand tourer and rural-road blaster to city slicker and urban warrior, thanks to the suspension’s ability to better-absorb a much wider array of terrible road surfaces. Comfort now lives up to its name, with the ride – though still firm – no longer hard or crashy around town, ushering in a new level of civility that won’t fatigue or aggravate you or your occupants. We're so happy to report this progress.

One area where BMW might want to keep improving, though, is the abundance of road noise intrusion over certain coarse chip bitumen. While easily muffled by the sweet sounds of the twin-turbo six, banging audio system or dropping the roof, it now seems more obvious that the rest of the car has smartened up so much.

A small fly in an otherwise hugely satisfying ointment.

Nothing you've driven before is like the experience of familiarising yourself with a GT-R, going from initial intimidation to trust and cooperation. This is a supercar for all moods and seasons.

Above all, though, and even without the launch control activated that helps it get to 100km/h from zero in 2.7 seconds (making it still one of the fastest production cars in the world), the Nissan is ferociously fast.

That’s no shock at all, but what is further imprints on you the GT-R’s outstandingly broad capabilities, since it can pussyfoot about in Comfort mode like any reasonably well-sorted grand-touring sports sedan, like a tame lion. In such circumstances, the car's mechanical congeniality is testimony to the sheer scale of engineering talent going on behind the scenes.

Choose Sport or Race modes, and the forces that the 3.8-litre twin-turbo V6 unleash are nothing short of seismic, swelling up and subsuming you in a tidal wave of relentless thrust that just doesn’t let up. With the exhaust wailing and the scenery blurring by, it is starkly clear that the GT-R is a supercar of tremendous speed.

Over the years, Nissan has improved the dual-clutch transmissions operation, reducing the driveline's abrupt clunkiness that marred earlier versions, for a smoother and yet still bolt-action rifle-rapid shifter that serves to facilitate all that walloping performance. In the sportier modes, with the configurable dampers, torque split and traction settings unshackled, a ham-fisted driver can still illicit a thump from the gearbox as it clumsily engages the ratios required, but overall, it’s a far-more seamless mover and shaker than before.

As you’d expect, the steering walks a fine line between agility and heft, responding calmly yet quickly, for direct and decisive handling. The GT-R feels hunkered down at all times, and it seems to dig in even more as you turn up the wick, unfazed by turns or the state of the road below.

What’s impressive is just how deceptively fast this is, since the car glides along so effortlessly. Yes, there is the engine's alluring aural soundtrack to remind you of the vast speed you potentially might be doing, but the chassis’ incredible control numbs your sense of speed.

While the suspension is set up for firmness, the adaptive dampers help calm the ride, bringing a sophisticated suppleness over most urban terrain. There isn’t much ground clearance at 107mm, but the double wishbones and multi-link arrangement does a terrific job filtering out the bad stuff. Furthermore, backed up by fiercely instantaneous brakes, the Nissan never feels nervous nor unsettled.

Sure, it’s far from quiet, with a decent amount of road noise droning through over some types of country roads, but it’s rarely challenging or distracting. The large turning circle is one of the few faults, in an otherwise satisfying driving and dynamic experience.

It's important to note that, though the styling has hardly changed over the years, the GT-R has evolved and developed for the better over time. For a supercar, its range stretches from benign to ballistic and from mellow to unmerciful, with towering confidence and control.

There are 28 very lucky drivers in Australia right now, wondering whether the replacement will also display Miss Congeniality and Conan the Barbarian with such charming authority. Drive a GT-R to realise how close to greatness it remains to this day.

There is no Euro NCAP or ANCAP crash-test rating for the Nissan GT-R.

Standard safety features include six airbags (a driver’s knee airbag, dual frontal, side chest and head-protecting airbags for the first and second row), rear view camera, parking sensors, anti-lock brakes with electronic brake-force distribution and brake assist, stability control, traction control, tyre-pressure monitors, LED headlights with active cornering and light sensitivity and rain-sensing wipers.

Given the GT-R’s age, you shouldn't expect nor find AEB, forward collision warning, front- or rear cross traffic alert, lane departure warning, lane keep assist, blind spot monitor or any other modern driver-assist tech. This Nissan is from when Silverchair's Straight Lines topped the charts.

There are, however, two ISOFIX points as well as two top tethers for straps in the rear seat area.

We feel here is where the company drops the ball.

Trailing all of its main luxury car rivals (except Porsche) by two years, BMW only offers a three-year/unlimited kilometre warranty, as well as three years of roadside assistance.

BMW says its vehicles’ servicing is condition-based, depending on how they’re driven and other factors, with a dash warning appearing to let the driver/owner know when it’s time. We advise servicing your M4 annually or at every 10,000km, just to be sure.

No capped-price servicing system is offered. However, as long as the first one is paid for before the first service on a new vehicle, the ‘BMW Service Inclusive Basic packages’ is available at extra cost, covering scheduled servicing for three years/40,000km or five years/80,000km.

No prices are published for M models like the M4, but a normal 4 Series costs from $1800 for the five-year/80.000km package. You can bet an M4’s will cost more.

The warranty period is for five-years/100,000 kilometres, with service intervals fixed at every six months or 10,000km – whichever occurs first. There is also five years of roadside assistance.

Unlike all other Nissans officially imported in Australia, there is no capped-price servicing for GT-R. And it requires specially trained service technicians so contact Nissan to find out which dealers can carry out the task.
