Nissan GT-R vs BMW 6 Series

What's the difference?

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.

This isn't a car for everyone's tastes, but if you fit in to the buyer group that just doesn't really know what they want in a luxury car, it could be the perfect fit for your family. The 6 Series GT is a practical large prestige car, albeit one that will likely find very few buyers.

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. 

There is no denying the 6 Series GT looks better than the old 5 Series GT. It isn't as frumpy, it looks more sporty, and to me it appears to have grown into its identity with more conviction than its predecessor.

That said, I don't necessarily like the look very much - it's a bit like a BMW X6 that has been rounded off a little and lowered down substantially. But I can appreciate some of the finer design aesthetics that it offers up: the frameless windows are a nice touch, and the swooping roofline looks smoother than a duck's back.

Other things like the active grille shutters and the air breathers ahead of the front doors are nice functional touches, and to my eye it lives up to BMW's hope of it looking "smooth but muscular". You can get the 630i with either the M Sport package, like you see here, or the more sedate Luxury Line, which is, well, more luxurious looking.

The M Sport styling and equipment package you see in the images here - with M aero kit and 19-inch wheels (ours had been upgraded to optional 20s) - help out with the athletic look of this very big vehicle.

It's huge in fact. The length of the 630i is 5091mm long, it measures 1902mm wide and sits at 1538mm tall, with a lengthy 3070mm wheelbase.

All that equates to a lot of room in the cabin, and what a sumptuous and delightful place it is to be - leather, wood and plush finishes abound.

“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.”

Now, I said before that this is a bit like an X6, but it has heaps better interior space than that SUV.

As soon as you slide into the driver's seat, you feel like your inside a large car. The cabin space is plentiful, and there's an abundance of storage on offer, too: there's a split-lid armrest between the seats, a pair of cupholders, a phone storage nook with wireless charging, and big door pockets with bottle holsters.

In the back you have access to door pockets, a flip-down armrest with cupholders (that middle part of the seat can fold down completely to allow storage of longer items), and there's excellent room on offer. How many seats in the BMW 6 Series GT? Five - like, five full-size seats.

Because the roofline doesn't rake as sharply as a four-door 'coupe', headroom is excellent for adults (even of the 183cm variety, like myself), and legroom and toe room are equally very good. This is bigger in the back than a 5 Series, but maybe not as plush as a 7 Series… so I guess it makes sense numerically for its nomenclature.

Of course you get climate control in the front (and in the rear if you option it), and the materials are excellent. The media screen is tablet-style, proudly displaying 10.25 inches of high-def real estate that is both touch-capacitive and controllable by way of the central rotary controller with touchpad. And get this - you can even use gestures to control certain elements like volume, swiping and changing tracks… but you have to option that.

The fully digital instrument display is bordered by a set of incomplete dial rings, which is just odd. BMW, back yourself - your buyers can handle just having a digital screen in front of them, particularly when it's as good as this one.

This grandiose hatchback's boot is commodious - with the back seats in place it has a huge 610 litres of cargo capacity, which extends to 1800L with the 40/20/40 seats folded down using the quick release levers in the boot area.

There is no spare wheel (the BMW range is fitted with run-flat tyres) but it does have a secondary hidden storage area under the boot floor for hiding items or stowing wet gear, bathers/swimmers or muddy clothes.

For context, the X6 has 580L seats up, 1525L seats down.

The BMW 6 Series Gran Turismo range starts off with the model tested here, the 630i. It has a list price of $123,500 before on-road costs - and that's whether you buy the M Sport Line or the Luxury Line.

That's quite a lot of money. And while it has a lot of equipment to help justify the cost, the smarter dollars will probably find their way to a more affordable 5 Series.

Standard gear in this spec includes adaptive air suspension with multiple drive modes, a colour head-up display, semi-autonomous parking, adaptive cruise control with steering assistance, auto high-beam LED headlights with LED daytime running lights, DAB+ digital radio, a 16-speaker harman/kardon sound system, a 12.3-inch driver information screen and a 10.25-inch media display with sat nav, Bluetooth and 'BMW ConnectedDrive' online services.

Hey, you even get a panoramic sunroof as standard! Plus there are things like an active rear spoiler, two USB ports and four 12-volt outlets, leather trim, heated front electric seats, electric steering wheel adjustment, keyless entry, push-button start, and an automatic boot.

It also comes loaded with active safety assistance functions - we'll get to that in the safety section below.

Things it's missing at this price point? Well, heated seats are an option, but bundled nicely into the 'Comfort Package' ($3000) which was fitted to our car. The pack includes heated seats front and rear, quad-zone climate control, electric sunblinds for the rear side windows, and electric seat back adjustment. Oh, and BMW continues to gouge consumers $623 for Apple CarPlay (which seemingly didn't work in our car).

The only other 6 Series GT model available is the 640i xDrive, which is again available with the choice of M Sport or Luxury body styling. It's also pretty exxy, with a list price of $148,900, but gets a more performance-focused drivetrain, as well as extra equipment: essentially the Comfort package, plus vented front seats, interior fragrance (eight options), memory settings for the front seats, 20-inch wheels and metallic paint.

Plus the 640i has Sport+ settings - it's probably the wrong car for those - and 'Integral Active Steering' to couple with the all-wheel drive system.

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.

Under the bonnet of the 630i is a 2.0-litre four-cylinder turbocharged petrol engine, which produces 190kW of power (at 6500rpm) and 400Nm of torque (from 1550-4400rpm). It uses an eight-speed automatic transmission, and is rear-wheel drive.

That may not seem a lot considering the size of this machine, but consider that some of the steamiest four-cylinder hot hatches have nearly the same outputs, and you realise this engine offers up a far-from slouched approach to propulsion.

The 640i xDrive has a 3.0-litre six-cylinder turbocharged engine with 250kW of power and 450Nm of torque. It gets the same eight-speed auto, but as the xDrive naming indicates, it's all-wheel drive.

But this is the one you'd prefer if you want to hit highway speed in a hurry - the 0-100km/h claim is 5.3 seconds, where the 630i takes a full second longer (6.3sec) according to the company.

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.

BMW claims fuel use of 7.0 litres per 100 kilometres, and you'll need to use 95RON premium unleaded when you fill up.

On my trip with the car, I saw about 9.0L/100km across mostly high-speed driving - some freeway, some highway, some country back road touring, and quite a bit of corners and city stuff thrown in as well. I think that's pretty respectable.

What wasn't so great was the lack of premium fuel in some of the 'away from civilisation' places on my route home. Keep that in mind if planning your own GT long-distance cruise.

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.

I'll put this out there - if you like to drive, there are BMW models for less than this one that will put a much bigger smile on your face. Like, a 440i Gran Coupe, or even just a 330i sedan…

But if you're in BMW's target market - that being older executive buyers who want space and luxury as a priority over thrills at the wheel, you could do a lot worse.

That's because the 6 Series GT lopes along the highway without fuss - the engine easily coping with the demands of overtaking moves, the adjustable drive modes allowing a light steering and wafting suspension feel to wile away the kilometres.

There are 'Comfort' and 'Comfort Plus' modes, but the latter is a bit too spongy and can be boaty feeling. The Comfort setting is made for the highway.

It is actually pretty agile for its dimensions.

If you decide to deviate from the straight sections, you'll be able to explore a little bit of dynamic range, especially when you dial up the 'Sport' mode, which changes the damper settings, steering weight, throttle and transmission response, and even the digital dials in front of the driver to a more aggressive look.

Our car had the 'Integral Active Steering' setting, which is a variable ratio steering system that includes rear steering - that essentially helps make is more turnable in corners at highway speed, and easier to park at lower speeds. It's difficult to say whether the assistance is excellent or not short of driving a car without the tech, but to this tester it was hard to hide the size and weight (1835kg kerb weight) of the vehicle.

That isn't to say it's clumsy or lumbering - it is actually pretty agile for its dimensions, though it makes a lot more sense on long drives and coastal cruises than it does in the narrow and twisty alpine roads of the Snowy Mountains Highway that I tested it on.

There's good grip from the tyres, and strong response from the powertrain - but if it were my money, and I had to have a 6 Series for whatever reason, I'd be looking towards the 640i model, which has a thumping six-cylinder with 250kW/450Nm - certainly an engine that would be more at home in this car. Plus that model comes with AWD.

The BMW 6 Series GT range has a five-star Euro NCAP crash test score based on 2017 testing, but it hasn't been scored by ANCAP.

There's the usual array of airbags - dual front, front side, full-length curtain and driver's knee airbags are included, plus parking sensors all around, and heaps of safety tech including the 'Driving Assistant Plus' package with lane departure warning and lane keeping assist, forward collision warning, auto emergency braking (AEB) front and rear, blind-spot monitoring and rear cross-traffic alert, and adaptive cruise control with stop and go.

That's all great stuff, and so is the 360-degree camera system with adaptive display - so, if you're reversing and you turn the wheel to one side, the image on screen will move, too. It'll also go between a birds-eye view and a backing-up perspective, and that can take some getting used to.

What was less convincing in terms of the user experience was the rear auto braking, which seemed to be scared of the car's own shadow. On multiple occasions the car jammed on the brakes when reversing out of driveways on to empty streets - be it in the normal height, or the raised height setting.

The 6 Series GT has dual ISOFIX anchor points and three top-tether points are there and ready for baby seats or child seats.

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.

BMW runs a condition-based servicing plan, which means the car will tell you when it needs servicing. But you can rest assured it won't (theoretically) cost you much, with the brand's 'Service Inclusive' pack. It covers you for basic maintenance as and when required for five years/80,000km. According to BMW, that includes "annual vehicle checks, oil changes, all filters, spark plugs and labour costs for the duration of the package".

BMW offers a three-year/unlimited kilometre warranty plan, and you get the same cover for roadside assistance.
