What's the difference?
When I say this is a rare review, I’m talking about the kind of rare that means you can’t even buy the car you’re reading about.
The 2026 Audi RS6 Avant GT you’re looking at in the pictures around this story is number 248 of 660. That’s six-hundred and sixty worldwide.
In Australia, there are only 22 RS6 GTs, and they’re all sold - at exorbitant prices, mind you, but we’ll get to that.
The RS6 GT is essentially a production version of the Audi RS6 GTO concept, built in 2020 and inspired by the Audi 90 quattro IMSA GTO race car, which means the RS6 GT carries a lot of ‘90 GTO’ in the way it looks. More on that shortly.
Aside from its extremely limited availability and its design package, there are some mechanical changes to increase the appeal of the RS6 GT, though whether any of its owners will put the on-road (or on-track) ability of this special wagon from Ingolstadt to the test remains to be seen.
A couple of days to live with one of the few RS6 GTs in Australia should reveal how special this car feels, and result in at least one example of the rarity being driven good and proper.
The dual-cab ute market and light truck market are potentially two very different landscapes.
While the dual-cab continues to storm the sales charts in Australia, there’s also a growing awareness among hardcore users of these vehicles, that a light truck might often be a better solution.
Better payloads and higher Gross Combination Mass ratings in an age of increasing legal and insurance concerns over overloaded vehicles, were once the light truck’s strong suit. But these days, vehicles like the full-sized US-made pick-ups and even the muscled-up Ford Ranger Super Duty have bridged or even exceeded that gap.
At which point, the light-truck’s benefits become the ease with which it can take on heavier jobs and the sheer size of the cargo and cabin area, not to mention those truck-specific qualities born of generations of refining a concept.
In Australia, it’s Isuzu that absolutely brains the opposition in sales terms. And part of the reason for that has been a realisation that not all would-be buyers want the hassle of the traditional truck-buying process of purchasing a bare chassis and then equipping it so suit their needs.
Which is where Isuzu’s RTW (ready To Work) concept comes in. You simply choose the truck you want, choose a tray, van or service body and then let Isuzu deal with it and phone you when it’s ready to collect.
It's so simple, it’s a wonder not everybody is doing it.
The other news is that Isuzu has finally updated its popular N Series fleet after about 16 years. A new cabin, extensive chassis changes, uprated engines, and all-new transmission, improved suspension and a new focus on safety are all headlines. But 16 years is a long time between drinks, so do the improvements make enough of a difference to keep the concept relevant in a changing market?
You’ll notice a number out of 10 on this review, you should ignore it.
Not only is it irrelevant because you can’t buy one, but the RS6 Avant GT isn’t a ‘brain’ car, it’s a ‘heart’ car. As much as a five-seat wagon can be, anyway.
Whether you think it’s overkill, overpriced, or overhyped, the GT is a celebration of a car that’s become such an icon for petrolheads. It’s also probably a marker for the end of an era, because we don’t see many V8 family cars getting about anymore.
Well done to Audi, the accounting team in particular, and if anyone who owns an Avant GT is willing to let me have another drive, my in-box is open.
Or I’ll just keep an eye out.
A truck like the NPR (or any other truck, really) is never going to replace a dual-cab ute in terms of its duality. While the latter can tend to weekday chores and be quickly reconfigured for weekend fun, the light truck has no such facility. Nope, it’s a workhorse. Period.
You need a fair bit of real estate just to park the Isuzu overnight and it certainly won’t fit in the typical supermarket car space. It’s hardly sporty to drive, either, although the latest upgrades have made it more user friendly in a total sense and safer than ever before.
But what it does do that a dual-cab ute can’t often do, is tackle bigger, heavier jobs with a fair bit of bandwidth still up its sleeve. And if the nine-to-five side of things is where you need to be, then a vehicle like this has to be worth a look. And if you consistently find that you’re sailing close to the wind in terms of exceeding a ute’s legal payload, towing capacity or GCM, then the extra bigness of a light truck could make a huge difference.
That’s especially so given the price tag. Okay, you’re not buying a lot of high tech for your money, but you are getting some seriously stout engineering and an expectation that you won’t be working the thing to death anytime soon.
Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.
“It looks like a toy car you’d get in a Kinder Surprise” was the first comment from my housemate upon seeing the $400K collector's item on wheels.
Harsh, but to anyone unfamiliar with the Audi 90 quattro IMSA GTO racer, there’s arguably too much going on with the RS6 Avant GT.
The red, grey and black decals, the chunky white 22-inch wheels, the flared and vented front fenders and the wing over the rear window… all of it is a lot to take in, but it’s very faithful to the IMSA car.
As pictured, the 90 quattro IMSA has the red around the bottom lip of the car, on the bonnet, and even its rear wind, the same as the red on the rear of the Avant GT.
Some of the black at the front of the car, where the bonnet and fenders are, is just exposed carbon-fibre rather than a black decal.
Short of the sponsors and racing numbers, the Avant GT does a fabulous job of paying homage to the 1989 race car. It just means you’re going to be the centre of attention anywhere you drive. Or park.
On that note, an alternative paint and graphic scheme in 'Mythos Black' (this car is 'Arkona White') was available to customers and is decidedly more ‘under the radar’. You have to wonder, though, if you opted for the subtle version of a car that pays homage to a fire-breathing IMSA car, would you feel like you took the coward's option?
Besides, you’re either keeping this car in some kind of temperature-controlled bubble, or (hopefully) spending most of your time around it in the driver’s seat. From there, you don’t have to grapple with the question of garishness.
The interior is, while elevated past standard RS6 vibes, a lot more subtle. Dark materials of microfibre, carbon, leather and the smudge-prone piano black (an Audi favourite) are joined by a relatively restrained serving of red in the contrast stitching and seatbelts.
It can’t be easy to make a light truck look fashionable, but Isuzu has done a reasonable job of making the thing look, at least, current. The lighting has all been changed to LEDs now, and the bold, angular face the truck presents looks pretty modern.
But new tech has also forced some design changes. The bull-bar that is part of the Tradepack deal, for instance, has been redesigned with changes to the main hoop. That’s all to accommodate the radar units inside each headlight that inform the front cross-traffic warning system of anything in the way.
Also notable is the attention to detail of the optional (rather than the alloy tray seen here) Australian-made service body. With a choice of internal layouts, the flip-up sides reveal a proper workshop on wheels when configured that way.
It’s also nice to see that all the clips and catches on the drop-side tray can be easily replaced if damaged.
You’ve bought a $400K collectible sports car capable of effortlessly deleting kilometres of highway with your family and enough luggage for a week. Usually a special edition driver's car at this price point is doing well if it has a place to put a phone and a water bottle, let alone phones and water bottles for four people - five if you really need.
Yes, in the performance car world, the Audi RS6 Avant has long been king of the convenience game and the GT holds onto that.
The seating position and ergonomics remains comfortable, the driver’s seat being manually adjustable means it can sit even lower, there’s decent storage in the door cards, cupholders are able to be hidden, the phone charger is under the armrest, there’s a spot for small items like keys, change or glasses and the rear seats have mostly the same alongside their own individual climate controls and heated seats.
Behind those, a 548-litre boot puts most performance cars to shame, but its 1658L space when the rear seats are folded down is unbelievable for something that you’d want to take to a race circuit.
The new cabin Isuzu has brewed up certainly brings the truck into the present, but it’s still very much a light truck in some respects. As in, it’s still a pretty good climb inside, although there are steps and handles to make that easier. The steering column still gets in the way as you swing your left leg inside, though.
The plastic surfaces would still make a car interior designer cringe, and the floor is vinyl and the seats cloth. But the three-abreast seating arrangement makes sense and, should you choose the dual-cab N Series option, there’s actually seven seats in all.
Cabin storage has obviously been a priority for Isuzu, and there are three large, netted overhead bins above the top of the windscreen, as well as bins and buckets across the width of the lower dashboard. Interestingly, each door has just a single, slim pocket and no bottle storage.
The centre console addresses that somewhat with a pair of cup-holders and a pen slot, while there’s also a large bin behind the seat on the bulkhead. There’s also an interior light that wouldn’t look out of place in an industrial kitchen.
The dashboard is home to a pair of USB charge-ports in the centre and the truck stuff continues with a wand for the exhaust brake and a knob near the steering column for a fast-idle setting. It’s also nice to see that even though Isuzu has adopted keyless entry and start for the N Series, the starter button resembles a conventional key and is located right where it should be in the side of the steering column.
What’s missing? Mainly a vanity mirror on either side of the cabin and a physical volume knob for the stereo. Oh, and paddle shifters would be nice too, especially when towing.
Externally, the Tradepack option gets you an aluminium drop-side tray, sturdy ladder racks, a tow bar, bull bar, toolboxes fitted below the tray between the axles and even a wash station for after-work clean ups.
The tray is fitted in Australia (many of the Ready to Work body options are also made here) and the load floor is a vast expanse of alloy with the ability to cope with small, heavy objects thanks to its high-impact materials. But the usual drop-side tray caveats apply including a high loading height, rattling from the sides and the legal requirement to lash everything down before hitting the road.
Meantime, part of the overall appeal of the Isuzu line-up is that there are something like 40 different permutations of cabin width, wheelbase, GVM, overall length and driveline.
But here’s perhaps the N Series’ greatest trick when it comes to being practical: While it’s easy to dismiss the vehicle for being too big and unwieldy, many operators would possibly find that the extra payload and real estate in the cargo area means that they might not need to tow a trailer every time they venture on to a job site. At which point, the dual-cab ute with a tandem trailer starts to look less convenient, especially if there’s any reversing or squeezing on to a tight site involved.
Oh, and if tight spaces really are an issue, the N Series’ sub-10m turning circle makes a typical dual-cab’s 12.5 metre turning circle look ridiculously ungainly. And that’s before we get to that trailer.
Typically for a vehicle like this, a full-sized spare tyre is included.
I’ve been told I’m not allowed to swear in CarsGuide reviews, so add your own expletive when I say, at $399,000, before on-road costs, the RS6 GT is expensive.
A ‘standard’ Audi RS6 Avant Performance costs $252,600, so you would really, really hope that warm feeling you get from owning one of only 22 GTs in the country is worth around $146,400. It’s very hard to imagine the physical changes to the car amount to that much money.
Of course, there’s plenty of kit in the RS6, anyway. But unique to the Avant GT is a carbon bonnet, carbon wing mirrors and carbon front fenders, a restyled spoiler, tailgate, and rear diffuser, 22-inch Audi Sport six-arm ‘Avus’-inspired alloy wheels (in white or black), RS ceramic brakes and black badging.
Inside, there are RS front bucket seats trimmed in leather, synthetic suede and carbon, contrast stitching in red, red seatbelts, black synthetic leather along the dashboard with open-pore carbon, rear window sunshades and a Bang & Olufsen 3D sound system from the 'Sensory Package' as standard.
There’s also ‘RS6 GT’ scuff plates, floor mats, puddle lighting and the individual number for each of the 660 cars on the centre console.
There’s also manually adjustable coil-over suspension and a GT-specifically-tuned quattro sport differential.
It’s cool, but is it an extra $146K cool?
For the price, you’re almost in Ferrari territory, or you’re ticking some options boxes on your Porsche 911 Carrera T. Suppose neither of those can comfortably take a family of four on a holiday to the snow and even feel safe driving on icy roads, though.
It does happen to be about the same price as the Mercedes-AMG GT63 S 4 Door, though whether that looks as good as the RS6 is debatable.
Like the rest of the N Series line-up, the NPR Tradepack model we’ve chosen to review here is available in a range of cabin widths and wheelbases and even a choice of Gross Vehicle Mass. But first, let’s break down the badge. In Isuzu-speak, N stands for the smallest family in the light-truck line-up. As such, it can be driven on a normal car license in Australia.
The P stands for the GVM, in this case that license-friendly 4.5 tonnes, although you can opt for the higher, 6.5-tonne GVM at which point an endorsed license is required.
And, finally, R is Isuzu’s in-house code for a truck that is two-wheel-drive and uses conventional steel-spring suspension rather than air suspension.
Isuzu says the Tradepack option with its large tray and fittings is a very popular one, so that’s what we’ve concentrated on here. That pack equates to all the drop-side tray, racks and fittings, so it’s a comprehensive add-on. Of course, you can take your NPR as a bare cab-chassis, too, and save by swapping over the tray and fittings from your old truck.
Beyond the nuts and bolts stuff, the NPR includes LED lights all-round, heated and powered exterior mirrors (and they’re huge), keyless entry and start, cruise control, steering-wheel mounted controls, climate-control air-con, a suspension driver’s seat and a tilt and reach adjustable steering column. There’s also a 10.1 inch multimedia screen in the centre of the dashboard, digital radio, sat-nav and wired Apple CarPlay and Android Auto connectivity.
The features that tell you this is still a truck and not a passenger car include the steel wheels, cloth seat trim and vinyl flooring.
As it sits, the NPR Tradepack costs $86,014 on the road, but that’s an all-up figure, and not one where you then have to arrange your own accessories and bits and pieces. It’s also within a few hundred dollars of the Ford Ranger Super Duty Super Cab which, perhaps not so coincidentally, has an identical GVM of 4000kg, GCM of 8000kg and slightly more towing capacity of 4500kg versus the NPR dual-clutch’s 4000kg.
Audi’s venerable 4.0-litre, twin-turbo V8 engine remains at the heart of the RS6, though in the GT there’s no more power than the RS6 Avant Performance.
That means 463kW of power and 850Nm of torque delivered to all four wheels via an eight-speed torque converter automatic and Audi’s ‘quattro’ all-wheel drive system, making the RS6 Avant GT capable of a 3.3-second sprint to 100km/h, according to Audi. Top speed is a blistering 305km/h.
All this in a car I took to Coles.
Believe it or not there’s actually a family connection between the 3.0-litre turbo diesel in the Isuzu NRL and the Isuzu D-Max dual-cab and MU-X SUV.
While the displacement of the D-Max remains, the unit in the light truck has been retuned to liberate more torque at lower engine speeds. In this case, that’s 129kW at 2860rpm and 430Nm of torque anywhere between 1450rpm and 2860rpm. That gives the engine great flexibility, but the transmission also plays a part.
That’s either a six-speed manual or a nine-speed dual-clutch unit. The latter has either manual or fully automatic shift modes, and it’s worth is backed up by the potential for lower fuel consumption thanks to the inherent efficiency in such a transmission as well as the three extra ratios.
Designed and made in-house at Isuzu, the brand says it’s confident the wet-clutch unit doesn’t carry the potential flaws of some other dual-clutch units we could name. That said, Isuzu has downgraded the towing capacity from 4.5 to four tonnes if the nine-speed is fitted.
And just like any good truck, there’s the provision for a power-take-off on the side of each transmission option, as well as an exhaust brake to help the mechanical brakes when fully laden.
Unlike many light trucks before it, the Isuzu doesn’t get stuck with a rigid front axle. Instead, you get a proper independent set-up with coil springs, while the rear end remains a live axle with leaf springs in the interests of carting lots of heavy stuff.
Do you care about this section of the review if you’ve bought one? Surely not.
Anyway, Audi claims 11.8L/100km in terms of fuel consumption and you’d better believe it’s 98 RON minimum.
It’s got a 72-litre fuel tank, which was depleted rather rapidly on test. While driving conditions weren’t ‘fair’ in terms of the test given the content demands of a short-term loan, there’s probably a realistic figure somewhere between the claim and the 17.9L/100km I achieved over a few days.
This is a cursed subject in the truck segment, because there’s just no standard pattern of usage, nor a typical loading scenario. Some trucks will spend their whole lives heavily loaded going from red light to red light, others will be less burdened and driven between regional towns.
But what we can tell you is that unladen and driven sensibly, this truck should be able to return fuel consumption figures in the low teens per 100km. Throw the full payload and a trailer on the back and head for hilly country and you could easily double that and then some.
As such, the range from the 100-litre fuel tank is going to vary enormously, but should be somewhere between 500 and 800km.
The other thing to bear in mind is that the upgrade to this model has brought the Isuzus in line with Euro 6 emissions or their Japanese equivalent. So they now need AdBLue and there’s a 14-litre tank for that.
There’s something unfortunate about how good the Audi RS6 Avant GT is from behind the wheel. That’s knowing how few people will properly get to enjoy it.
Not just because only 660 were built, but also because the majority of those 660 owners will be too worried about how much they’ve just spent on an automotive rarity to properly take it for a burn on a road, or even a track.
The RS6 was always an icon of Germany's penchant for subtle-looking cars that just happen to be capable of embarrassing much more brash vehicles, but the GT does away with the pretence and sharpens its teeth a little.
The specifically tuned rear differential makes for a more rear-biased driving experience in Dynamic mode, which means more agile cornering and a more natural balance compared to the way the RS6 sometimes feels - like a family wagon.
Its rival, the BMW M5 Touring, can go full rear-drive, but the Audi doesn’t need that as an option. It feels more capable and composed; ready to obey commands without fuss. A set of Continental SportContact 7 tyres (285/30) help there on the grip front.
The suspension underneath, adjustable coil-overs with three settings, is unique to the GT and lowers the ride height by 10 millimeters. It’s stiffer, 30 per cent at the front and 80 at the rear, and you notice it.
There’s more control and much less body roll, but the trade-off is the RS6 Avant GT is a little less comfortable on Australia’s particularly rough roads. Its 22-inch wheels don’t help.
It’s not, however, crashy or rattly. The suspension still does a fine job of stopping the driver being jostled around, but there’s a decidedly firmer response to the surface underneath. Again, still very composed.
With the new suspension, steering the GT feels easier than memory would suggest and the baseline was already good. There’s no unnecessary weight, but there’s still decent feedback from the front wheels and accuracy is bang-on.
Throttle adjustment in the corners, too, is easier with the rear differential, and it means anyone who still had reservations about Audi and understeer can be proven wrong.
The drivetrain remains unchanged from the Performance, which is a good thing. The effortless acceleration, even in the more aggressive 'Dynamic' setting with the transmission set to 'Sport' is smooth but seemingly unending.
Fortunately, the 4.0-litre V8 under the carbon bonnet sounds delightfully burbly, so getting to the speed limit or overtaking is a little treat every time. While the steering wheel paddles are there if you really need to drive in anger, the eight-speed is fine left to its own devices.
A 2.0-tonne family wagon with a V8 up front, easy communicative steering, and sporty suspension that settles well over bumps but allows enthusiastic corner attacks?
The RS6 Avant GT is in limited company.
Actually climbing aboard the Isuzu is job one, and you’ll need the handles and step to do it safely. Then again, it’s probably no more testing than getting into a really low sports car in a degree of difficulty sense.
With that accomplished, you’re met with two things; the view out and the very un-car-like driving position. The first is fantastic for forward vision. And it’s not just the height advantage over other traffic. The cab-over-engine layout also means you’re almost at the very front of the truck, meaning you can see a lot more of what’s directly in front of you, even if it’s almost under your nose. Jumping back into a dual-cab ute for comparison emphasises the point enormously.
The driving position, meanwhile, might take more getting used to. The steering wheel is almost flat and you tend to sit pretty upright. Long-distance drivers will tell you this is actually great for long stints at the helm, and it honestly feels pretty natural after just a few minutes. But the steering column placement means there’s no chance of left-foot braking which some drivers (this one included) prefer.
Once you’re rolling, the dual-clutch transmission starts to feel pretty handy with short, sharp upshifts and a calibration that sees it keen to downshift on deceleration to help balance the vehicle, take the stress off the brakes and ensure that the engine is in its power band for when you next throttle on.
Speaking of which, the engine is not exactly overpowering, but it does produce the meat of its muscle in the right places, helped no end by having nine ratios to play with. And here’s an interesting point: The way the engine is installed in the NPR – and despite the fact that you’re sitting pretty much right on top of it – there’s less noise and vibration from the 3.0-litre than in an Isuzu D-Max ute. Obviously, low vibrations and less noise are factors in staving off driver fatigue, and clearly Isuzu knows how to achieve this.
Ride quality will vary hugely depending on what’s on board. We tried the NPR with a full load of gear on the tray, taking it almost to its payload limit. At that point, the ride was actually quite compliant, and the only odd sensation is that of having your backside right over the front axle.
The other mantra held dear by fleet managers is that the best way to reduce breakdowns is to take the driver out of the equation as much as possible. That explains the dual-clutch transmission, for one, but it also perhaps explains why the NPR is set up to be actually very easy and simple to drive. It’s definitely scarier to look at than to pilot. And that turning circle is something else!
There’s no current rating from ANCAP for the A6 in general, let alone this specific RS6, but there’s a decent suite of safety equipment and tech to keep you worry-free in the GT.
Eight airbags and more than 30 driver assistance systems from the RS6 are of course present in the GT, including adaptive cruise control, lane-keep and warning, emergency brake assist and cross-traffic alert.
Audi’s also got surround view cameras for parking, which also includes warnings for approaching vehicles or objects, plus there are preemptive measures the car can take in an impact like tightening the seatbelts or braking to avoid a second collision.
The second row also has three top tethers and ISOFIX anchor points on the outboard seats for mounting child seats.
You can absolutely thank OH&S legislation for the huge leaps in active and passive safety that vehicles like the Isuzu have made in recent years.
Although this class of vehicle is not required to be crash tested (and, therefore, there’s no safety star rating available) even a scant knowledge of physics suggests that sitting the passengers up high in a vehicle with a strong chassis is a very good start when it comes to crash safety.
Passive safety is also helped by an airbag for both driver and the two front-seat passengers in the case of the three-seat variant we’ve looked at here. But only the outboard passengers get a three-point seat-belt, and the centre position gets a simple lap-belt.
There are also side intrusion bars in the doors as per passenger-car best practice and the overhead storage space features a safety net. There are no side-curtain airbags, but again, that high seating position makes the N Series inherently safer for passengers in a typical side impact.
But it gets better with a long list of driver aids, most of them straight out of the current passenger-car playbook. Running changes to the vehicle over the years have seen the addition of autonomous emergency braking (AEB), anti-skid brakes, stability control, a driver attention monitor, a distance warning system for vehicles in front, brake-force distribution and lane departure warning.
New safety tech this time around includes front cross-traffic alert and braking, mis-acceleration (pedal-error) mitigation, traffic and speed-sign recognition, a distance warning system that also advises of the speed of the car in front and improvements to the rear camera system.
And yet, there’s probably more work to be done here. We’d like to see a standard 360-degree camera and tyre pressure monitoring as well. These are both available at extra cost right now, but really should be standard on a vehicle like this. Rear cross-traffic alert is also missing, but that’s more about standardising the sensors and their calibration on a huge range of rear-body designs, apparently.
There’s also an apparent tech gap to be bridged, too, and right now only the dual-clutch-equipped version gets the speed limiter and adaptive cruise control, while the conventional manual does not.
Isuzu is also making a big noise about the new electronic park brake which can be used in an emergency to bring the vehicle to a complete, controlled stop if necessary.
Audi’s five-year/unlimited kilometre warranty is below industry par, though most premium brands are in the same boat.
Twelve years of bodywork warranty against corrosion is also included, as is a five-year run of free Audi roadside assistance.
Five-year service plans can be purchased, or customers can buy back-to-back two-year extensions for the warranty, servicing and roadside assistance.
Despite the hard life many trucks are destined to live, Isuzu offers a standard six-year/250,000km warranty on the cabin and chassis of this model. The rear RTW body (whatever form that takes) is covered for three years. There’s also a three-year warranty on genuine accessories provided they were installed by a certified fitter.
Service intervals are every 25,000km, 12 months or 5000 hours of operation, whichever comes first. There’s also six years of roadside assistance thrown in.
Isuzu offers a range of service agreements ranging from the basic package right up to a plan that covers everything including wiper blade replacement.
There are currently 84 Isuzu dealers or authorised service outlets around the country, including some pretty far flung spots, so service and parts should be less of a problem than for some other brands.
Mechanically, Isuzu has worked to reduce servicing times, including the use of sealed-for-life wheel bearings.
