Audi A6 vs Nissan GT-R

What's the difference?

I was thoroughly impressed by the Audi A6 Allroad 45 TDI quattro 2020 model. It is excellent on road, resolved and comfortable on unsealed surfaces, and very well packaged for family touring.

I’d personally have it in a heartbeat over a Q7 or any SUV, for that matter. I can understand why some buyers wouldn’t consider it, but if you’re someone who likes to think outside of the boxy SUV, then be sure to take a look at the Audi A6 Allroad.

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.

If this isn’t the best looking genre of car, I must have been blindfolded since birth. You might think differently - be sure to let me know in the comments section below.

But for me, I just love the idea of a station wagon that is beefed up with SUV styling cues, and the Audi Allroad formula has been en pointe for generations now. This latest A6 Allroad doesn’t disappoint, either, with all the elements you’d expect.

Things like the bulging contrasting wheel-arch liners, the rugged underbody protection bash plates, and even the silver roof rails and silver metallic side sill protectors with ‘quattro’ emblazoned upon them - it just all works. 

And being an Audi A6 wagon underneath the glittery bits, it’s a sizeable vehicle. The dimensions read like so: length - 4951mm; wheelbase - 2925mm; width - 1902mm; height - 1458mm, though that depends on the height of the air suspension. 

The A6 Allroad sits about 45 millimetres higher than the standard A6 Avant wagon (not sold in Australia). And the ground clearance also varies depending on the air suspension height setting, but it is officially recorded at 139mm - which isn’t very high at all, but that’s for the regular driving setup. In its raised height, that jumps by 45mm to 184mm. Nowhere near an off-road Toyota, but still high enough to stop the belly from scraping.

And there are other hardware bits to help you out if the going gets tough - out of sight is Audi’s ‘quattro’ all-wheel drive system with a self-locking centre differential that the brand says provides “superior traction and its high level of safety and agile handling”. There is hill descent control, and the infotainment screen can display the location, elevation, compass and driving angles, too.

As for the design of the interior? It’s high-tech Audi opulence and comfort at its best. Check out the interior pictures to see what I mean.

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. 

Technical. Practical. Glorious. Three words I’d use to describe the cabin of the Audi A6 Allroad. 

The cockpit isn’t anything out of the ordinary for an Audi of the modern era, and as such it will feel familiar to you if you’ve been in or around any of its more recent stablemates. It also means that you’ll find yourself in a high-end, high-tech and highly pleasant interior. The materials used are beautiful and of a high standard. They look very nice and it is an extremely pleasant place to be. And you can hate on me if you want, but I’m sold on brown leather. Yummo!

It will take some time for you to get to grips with the dual-touchscreen layout of the cabin, but once you get the hang of it, it becomes second nature.

The media screen is very easy to use, the menus are simple to learn, and over my week there were absolutely no issues with Apple CarPlay - either when connected via USB, or when used wirelessly.

The second screen below controls a lot of the main functions of the air conditioning system, and while I’m not a huge fan of using a screen to touch through temperature and fan controls, this one has haptic feedback and is well positioned - it’s not as much of a glance away from the road as in, say, a Land Rover or Range Rover. There’s also a volume knob which is good, and quick buttons for Drive Select and demister for front and rear windscreens.

In terms of the practicalities, there are bottle holders in the doors, a pair of cup holders between the front seats, a covered centre console bin with Qi wireless phone charging (remember not to leave your phone in there!) and there are two USB ports in there, plus a SIM card slot and SD card slot as well.   

The seat comfort is very good - there’s electric adjustment on both seats with lumbar adjustment, and the driver’s seat gets memory settings as well. The electric steering wheel adjust is a nice touch as well, and there’s a remote boot release trigger, too.

There are twin sunroofs, and the front one can tilt and slide while the rear one is fixed. It helps lighten things up a bit if you have the optional dark headlining, which I personally wouldn’t choose.

Rear seat space is excellent. Sitting behind my own 182cm driver’s seat position, I had easily enough legroom, headroom and shoulder room - in fact, the rear pew is so accommodating, it could easily fit three of me across - but foot space is a little tight due to the large transmission tunnel. 

Those in the back are well catered for – there are 2x USB ports, a pair of large door pockets with bottle holders, twin mesh map pockets, a flip down armrest with storage and cupholders, and our car had quad zone climate control (as part of the optional Premium Plus package - standard is three-zone climate), plus there are centrally mounted directional air vents and in the door pillars at face height. Our tester also had those optional manual sunblinds, which would certainly help those in the back get some shut-eye on longer trips. 

The centre section of the rear seat can be split folded down on its own as well – so you have 40:20:40 rear seat folding, which is great for skis or snowboards. Plus there are two ISOFIX child seat attachments and three top-tether points available for baby seats. And one of the most excellent additions to any car ever – illuminated seat belt buckle receivers. It just makes it that much easier to see at night.

If you need to fold down those rear seats, there are boot-mounted triggers. That’ll help expand the luggage capacity from the standard 565 litres (VDA) to an expansive 1680L (VDA). The cargo hold easily fit the three CarsGuide suitcases (124L, 95L and 36L) with room to spare.

There is no Audi Allroad seven seater, though. And that’s potentially where something like a Q7 makes more sense, depending on your intent. 

“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.

Under the bonnet of the Audi A6 Allroad is what Audi labels the ‘45 TDI’ - a 3.0-litre turbo-diesel V6 engine that produces 183kW of power (from 2750-4500rpm) and 600Nm of torque (from 1500-3000rpm).

The engine is only available mated to an eight-speed torque-converter automatic transmission and Audi’s renowned ‘quattro’ all-wheel-drive (AWD) system. 

Audi claims this 1980kg wagon can run from 0-100km/h in just 6.5 seconds, on its way to a top speed of 250km/h. It is a hummer of an engine - more on that in the driving section below.

Towing capacity is pegged at 750kg for an unbraked trailer, and maxes out at 2500kg for a braked trailer.

Should Aussies feel short changed when it comes to the engine options here? Arguably, yes - and that’s despite the powertrain offered here still being a stormer. 

There’s only one spec available Down Under, and even it doesn’t get the most up-to-date emissions tech. There isn’t AdBlue urea treatment (meaning this is a Euro 5 engine), and our cars have essentially been de-specced to miss out on the latest 48-volt mild-hybrid tech, which is standard on all grades of the A6 Allroad in Europe. Maybe that is part of the reason the cost is down, this time around. 

And while the outputs of the 45 TDI in Australia are pretty decent, other markets have the A6 Allroad offered in 50 TDI (210kW/620Nm) and 55 TDI (257kW/700Nm) trims. Remember, though - this is a very niche player here. 

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.

Audi claims the 45 TDI powertrain in the A6 Allroad will use 6.6 litres per 100 kilometres. That’s the official Australia fuel consumption figure on the combined-cycle test. CO2 emissions are claimed at 174g/km.

During my time in the Audi A6 Allroad I saw an average fuel use return of 7.4L/100km - which was taken over highways, back roads, unsealed roads and twisty bits. There was even some urban stop-start in there, too. I think that’s pretty darn good for a car of this size.

Fuel tank capacity is 63 litres, meaning a real-world range of 851km based on my fuel consumption.

As mentioned above, the A6 Allroad is a mild hybrid model in other markets, but not in Australia. We don’t even get the Euro 6-compliant version here, as there’s no incentive for it to be offered locally - as in, there’s not even AdBlue treatment. 

There’s no electric version (though you might want to look at the all-new Audi e-tron)  or plug in hybrid, and no petrol model either.

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.

Here’s where the A6 Allroad separates itself from, say, an Audi Q5 or Q7. It’s a low-slung wagon, made for touring on country roads, doubling down on dirt backtracks and cruising comfortably on the freeway.

It’s not as upright as a Q5 or Q7, and that means it has a lower centre of gravity - so it feels more hunkered down, more settled into the surface below.  

And in the case of the A6 Allroad, there’s adaptive air suspension all around to cushion the car from what lies beneath. For the most part, that air suspension is superb - it absorbs big bumps and lumps very well, though the oversized 21-inch optional wheels can’t disguise sharp edges from those in the cabin. 

The general compliance is very good, and as I found out first hand, you can easily soak up hundreds of kilometres without feeling the affects of the road underneath you - even over bumpy country back roads and lumpy dirt sections.

The steering could be better; it’s a little bit vague and heavy on centre at higher pace, but at lower speeds it is light and amicable. Very easy to park despite its size, and easy to manoeuvre around town, too.

The engine builds pace with superb linearity, and it’s very quiet and refined as well. There is a tiny bit of turbo lag at lower speeds or from a standstill – but it is completely manageable and never feels like it’s sluggish at all. The 0-100km/h claim of 6.5 seconds seems achievable, too. 

The eight-speed automatic transmission was mostly very smart and well sorted - although in other VAG models with this engine family/eight-speed auto, the transmission never felt quite as busy at higher speeds. I noticed it shuffling between seventh and eighth gears more than I was expecting, given how much torque the engine has. It’s not annoying at all, and nor is it unrefined, and could well have something to do with attempting to save fuel rather than leaving it in top gear.

During night driving, the optional HD Matrix LED headlights were exceptional - among the best headlight technology that I’ve ever encountered. The ‘matrix’ technology means they can blank out oncoming traffic or cars in front of you while keeping the high-beam on in other areas. The auto headlights with auto high beam worked very well, too.

The plan was never to do a serious off road review, but I did do some driving on unsealed roads and found the Allroad to be excellent. 

Through slippery unsealed corners it exhibited excellent traction, though you can feel the weight of the car shifting from side to side when you pivot through corners. There was a touch of skittishness over mid-corner bumps, but again that could be more to do with the big wheels than anything else.

I came away thinking that if you had your eyes closed, you wouldn’t even know that you were on dirt or gravel. It really is an exceptional car across sealed and unsealed roads. 

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.

Audi offers a three-year/unlimited kilometre warranty, which is as good as BMW, but not as good as Lexus (four years/100,000km) or Mercedes-Benz, Volvo and Genesis (five years/unlimited kilometres). It’s falling behind in the luxury sphere.

The company offers reasonably priced capped price ownership plans for maintenance. Purchasers can roll in the cost of either a three-year service plan ($2170) or a five-year plan ($3300). That covers off the usual service items due every 12 months/15,000km.

Roadside assist is included for the period of the new car warranty.

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.
