Audi A6 vs Nissan Z

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 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.

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.

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?

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. 

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.

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. 

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?

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.

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.

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. 

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.

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.

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.
